this seems like a simple question but I couldn't find the answer. If I have a component path "pathToComponent", how can I validate that it is valid? Right now I am resorting to using try/catch, but surely there is a more elegant way?
boolean function isValidComponent( required string pathToComponent ){
try{
var metaData = getComponentMetaData( arguments.pathToComponent );
return true;
}
catch( any e ){
return false;
}
}
Thanks!
If you want to test if the component path can be used to create a component, use:
boolean function isValidComponent( required string pathToComponent ) {
try {
createObject("component", ARGUMENTS.pathToComponent);
return true;
}
catch(any) {
}
return false;
}
If you want to access the component physically, use:
string function getComponentLocation( required string pathToComponent ) {
var normalizedPath = replaceNoCase(ARGUMENTS.pathToComponent, ".", "/", "ALL");
var resolvedPath = expandPath(normalizedPath);
var fileLocation = (resolvedPath & ".cfc");
return fileLocation;
}

i want to filter the search string entered in a way that it doesn't accept anything other than the matched string for Searching.
Here is my Controller code:
public ActionResult SearchProduct(string SearchString)
{
FlipcartDBContextEntities db = new FlipcartDBContextEntities();
if(ModelState.IsValid)
{
// if ModelState is true
string noResult = "Search Result Not Found";
var products = from p in db.Products select p;
if (!String.IsNullOrEmpty((SearchString).Trim()))
{
products = products.Where(s => s.ProductName.Contains(SearchString));
return View(products.ToList());
}
else
{
ViewBag.Message = noResult;
return View(new List<Product>());
}
}
else
{
ModelState.AddModelError("", "Search not successful");
}
return View();
}
"Search Result Not Found" is displaying only for null entry..but i want it to display for any other characters that doesn't matches the search string.
How do i do that?
Try this:
if(ModelState.IsValid)
{
// if ModelState is true
string noResult = "Search Result Not Found";
//ternary expression to return a new list if Search string is null or empty
var products = string.IsNullOrEmpty(SearchString.Trim())
? new List<Product>()
: db.Products
.Where(s => s.ProductName.Contains(SearchString));
//set viewbag message if list is empty
if(!products.Any())
{
ViewBag.Message = noResult;
}
return View(products.ToList());
}
else
{
ModelState.AddModelError("", "Search not successful");
}
how to return some value from actions??
I tried this:
var t = this.send("someAction", params);
...
actions:{
someAction: function(){
return "someValue";
}
}
actions don't return values, only true/false/undefined to allow bubbling. define a function.
Ember code:
send: function(actionName) {
var args = [].slice.call(arguments, 1), target;
if (this._actions && this._actions[actionName]) {
if (this._actions[actionName].apply(this, args) === true) {
// handler returned true, so this action will bubble
} else {
return;
}
} else if (this.deprecatedSend && this.deprecatedSendHandles && this.deprecatedSendHandles(actionName)) {
if (this.deprecatedSend.apply(this, [].slice.call(arguments)) === true) {
// handler return true, so this action will bubble
} else {
return;
}
}
if (target = get(this, 'target')) {
Ember.assert("The `target` for " + this + " (" + target + ") does not have a `send` method", typeof target.send === 'function');
target.send.apply(target, arguments);
}
}
I had the same question. My first solution was to have the action put the return value in a certain property, and then get the property value from the calling function.
Now, when I need a return value from an action, I define the function that should be able to return a value seperately, and use it in an action if needed.
App.Controller = Ember.Controller.extend({
functionToReturnValue: function(param1, param2) {
// do some calculation
return value;
},
});
If you need the value from the same controller:
var value = this.get("functionToReturnValue").call(this, param1, param2);
From another controller:
var controller = this.get("controller"); // from view, [needs] or whatever
var value = controller.get("functionToReturnValue").call(controller, param1, param2); // from other controller
The first argument of the call() method needs to be the same object that you are running the return function of; it sets the context for the this reference. Otherwise the function will be retrieved from the object and ran from the current this context. By defining value-returning functions like so, you can make models do nice stuff.
Update I just found this function in the API that seems to do exactly this: http://emberjs.com/api/#method_tryInvoke
Look this example:
let t = this.actions.someAction.call(this, params);
Try
var t = this.send("someAction", params);
instead of
vat r = this.send("someAction", params);
Just use #set for set value which you want to return
actions:{
someAction: function(){
// return "someValue";
this.set('var', someValue);
}
}
I have following regex route, which allows me to use pagination - to parse URL and also build it:
; route "product-{brand}"
product.type = "Zend_Controller_Router_Route_Regex"
product.route = "product-([a-z\-]+)(?:/page/(\d+)/?)?"
product.defaults.module = "default"
product.defaults.controller = "products"
product.defaults.action = "product"
product.defaults.page = "1"
product.map.1 = "brand"
product.map.2 = "page"
product.reverse = "product-%s/page/%d"
Everything is working fine, however, I need to get the rid of default page. Currently we are migrating old web to the Zend and we need to preserve old links because of current google positions, etc.
With default "page", I'm getting always /page/1, without it Zend "cannot assemble" URL.
How to not display page 1 in URL ?
Finally, I've managed to achieve this, but only by rewriting Regex assemble method.
I'm simply overriding two methods.
Class extension:
class Utils_Router_Regex extends Zend_Controller_Router_Route_Regex
{
// instantiate
public static function getInstance(Zend_Config $config)
{
$defs = ($config->defaults instanceof Zend_Config) ? $config->defaults->toArray() : array();
$map = ($config->map instanceof Zend_Config) ? $config->map->toArray() : array();
$reverse = (isset($config->reverse)) ? $config->reverse : null;
return new self($config->route, $defs, $map, $reverse);
}
// in this case, we are using $this->_reverse as array from config
public function assemble($data = array(), $reset = false, $encode = false, $partial = false)
{
//// EXTENSION PART !!!
if( !isset( $data[(string) $this->_reverse->pagemap]) ) { // if not set url helper
$reverse = $this->_reverse->base;
} else { // if set in url helper
$reverse = $this->_reverse->paginator;
}
/// end of extension part
if ($reverse === null) {
require_once 'Zend/Controller/Router/Exception.php';
throw new Zend_Controller_Router_Exception('Cannot assemble. Reversed route is not specified.');
}
$defaultValuesMapped = $this->_getMappedValues($this->_defaults, true, false);
$matchedValuesMapped = $this->_getMappedValues($this->_values, true, false);
$dataValuesMapped = $this->_getMappedValues($data, true, false);
// handle resets, if so requested (By null value) to do so
if (($resetKeys = array_search(null, $dataValuesMapped, true)) !== false) {
foreach ((array) $resetKeys as $resetKey) {
if (isset($matchedValuesMapped[$resetKey])) {
unset($matchedValuesMapped[$resetKey]);
unset($dataValuesMapped[$resetKey]);
}
}
}
// merge all the data together, first defaults, then values matched, then supplied
$mergedData = $defaultValuesMapped;
$mergedData = $this->_arrayMergeNumericKeys($mergedData, $matchedValuesMapped);
$mergedData = $this->_arrayMergeNumericKeys($mergedData, $dataValuesMapped);
if ($encode) {
foreach ($mergedData as $key => &$value) {
$value = urlencode($value);
}
}
ksort($mergedData);
$return = #vsprintf($reverse, $mergedData);
if ($return === false) {
require_once 'Zend/Controller/Router/Exception.php';
throw new Zend_Controller_Router_Exception('Cannot assemble. Too few arguments?');
}
return $return;
}
}
Then you can define which sprintf string to use:
hodinky.type = "Utils_Router_Regex"
hodinky.route = "hodinky-([a-z\-]+)(?:/page/(\d+)/?)?"
hodinky.defaults.module = "default"
hodinky.defaults.controller = "products"
hodinky.defaults.action = "hodinky"
hodinky.map.1 = "znacka"
hodinky.map.2 = "page"
hodinky.reverse.paginator = "hodinky-%s/page/%d" ; assebmly with paginator
hodinky.reverse.base = "hodinky-%s/" ; assebmly without paginator
hodinky.reverse.pagemap = "page" ; "page" map key
If you have better solution, please let me know.
I'm Using EmailValidator for Validation:
<mx:EmailValidator id="Email_Validator"
source="{txtEmail}"
property="text" required="false"/>
And My Code is:
var isValidForm:Boolean=true;
var validatorArr:Array = new Array();
validatorArr.push(Email_Validator);
var validatorErrorArray:Array = Validator.validateAll(validatorArr);
isValidForm = validatorErrorArray.length == 0;
if(isValidForm)
{
//.....
}
It is working fine. But I want domain should be "gmail.com" if some other, validation should return false.. How can I achive this?
I think Regular Expressions are usefull.. But I dont Know to use the same in flex?...
If all you are testing for is "gmail.com", you don't need to use regular expressions at all. A simple
if (txtEmail.text.indexOf ("gmail.com") < 0) doStuff();
// index < 0 => address does not contain search string
would be enough.
Nonetheless, ActionScript 3 has the RegExp class to provide regular expression functionality. See this tutorial.
Use a component
checkout this
public class TextInputEmail extends TextInput
{
private var emailValidator:EmailValidator = new EmailValidator();
private var validator:ValidationResultEvent;
public function TextInputEmail()
{
super();
this.emailValidator.source = this;
this.emailValidator.property = "text";
this.addEventListener("enter", this.validate);
}
private function validate(event:Event):void
{
validator = emailValidator.validate();
if (validator.type == ValidationResultEvent.VALID)
{
this.errorString = "";
} else {
this.errorString = validator.message;
}
}
}
error strings are in build in Package.
I hope this helps you better...:-)
I'm not too sure how to do this. I need to validate email addresses using regex with something like this:
[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*#(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+(?:[A-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)
Then I need to run this in a jQuery function like this:
$j("#fld_emailaddress").live('change',function() {
var emailaddress = $j("#fld_emailaddress").val();
// validation here?
if(emailaddress){}
// end validation
$j.ajax({
type: "POST",
url: "../ff-admin/ff-register/ff-user-check.php",
data: "fld_emailaddress="+ emailaddress,
success: function(msg)
{
if(msg == 'OK') {
$j("#fld_username").attr('disabled',false);
$j("#fld_password").attr('disabled',false);
$j("#cmd_register_submit").attr('disabled',false);
$j("#fld_emailaddress").removeClass('object_error'); // if necessary
$j("#fld_emailaddress").addClass("object_ok");
$j('#email_ac').html(' <img src="img/cool.png" align="absmiddle"> <font color="Green"> Your email <strong>'+ emailaddress+'</strong> is OK.</font> ');
} else {
$j("#fld_username").attr('disabled',true);
$j("#fld_password").attr('disabled',true);
$j("#cmd_register_submit").attr('disabled',true);
$j("#fld_emailaddress").removeClass('object_ok'); // if necessary
$j("#fld_emailaddress").addClass("object_error");
$j('#email_ac').html(msg);
}
}
});
});
Where does the validation go and what is the expression?
UPDATES
http://so.lucafilosofi.com/jquery-validate-e-mail-address-regex/
using new regex
added support for Address tags (+ sign)
function isValidEmailAddress(emailAddress) {
var pattern = /^([a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+(\.[a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+)*|"((([ \t]*\r\n)?[ \t]+)?([\x01-\x08\x0b\x0c\x0e-\x1f\x7f\x21\x23-\x5b\x5d-\x7e\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|\\[\x01-\x09\x0b\x0c\x0d-\x7f\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))*(([ \t]*\r\n)?[ \t]+)?")#(([a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.)+([a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.?$/i;
return pattern.test(emailAddress);
}
if( !isValidEmailAddress( emailaddress ) ) { /* do stuff here */ }
NOTE: keep in mind that no 100% regex email check exists!
This is my solution:
function isValidEmailAddress(emailAddress) {
var pattern = new RegExp(/^[+a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/i);
// alert( pattern.test(emailAddress) );
return pattern.test(emailAddress);
};
Found that RegExp over here: http://mdskinner.com/code/email-regex-and-validation-jquery
$(document).ready(function() {
$('#emailid').focusout(function(){
$('#emailid').filter(function(){
var email = $('#emailid').val();
var emailReg = /^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/;
if ( !emailReg.test( email ) ) {
alert('Please enter valid email');
} else {
alert('Thank you for your valid email');
}
});
});
});
Lolz this is much better
function isValidEmailAddress(emailAddress) {
var pattern = new RegExp(/^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/);
return pattern.test(emailAddress);
};
I would recommend that you use the jQuery plugin for Verimail.js.
Why?
IANA TLD validation
Syntax validation (according to RFC 822)
Spelling suggestion for the most common TLDs and email domains
Deny temporary email account domains such as mailinator.com
How?
Include verimail.jquery.js on your site and use the function:
$("input#email-address").verimail({
messageElement: "p#status-message"
});
If you have a form and want to validate the email on submit, you can use the getVerimailStatus-function:
if($("input#email-address").getVerimailStatus() < 0){
// Invalid email
}else{
// Valid email
}
Javascript:
var pattern = new RegExp("^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*#[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$");
var result = pattern .test(str);
The regex is not allowed for:
abc#gmail..com
abc#gmail.com..
Allowed for:
abc.efg#gmail.com
abc#gmail.com.my
Source: http://www.mkyong.com/regular-expressions/10-java-regular-expression-examples-you-should-know/
We can also use regular expression (/^([\w.-]+)#([\w-]+)((.(\w){2,3})+)$/i) to validate email address format is correct or not.
var emailRegex = new RegExp(/^([\w\.\-]+)#([\w\-]+)((\.(\w){2,3})+)$/i);
var valid = emailRegex.test(emailAddress);
if (!valid) {
alert("Invalid e-mail address");
return false;
} else
return true;
Try this
function isValidEmailAddress(emailAddress) {
var pattern = new RegExp(/^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/);
return pattern.test(emailAddress);
};
you can use this function
var validateEmail = function (email) {
var pattern = /^([a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+(\.[a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+)*|"((([ \t]*\r\n)?[ \t]+)?([\x01-\x08\x0b\x0c\x0e-\x1f\x7f\x21\x23-\x5b\x5d-\x7e\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|\\[\x01-\x09\x0b\x0c\x0d-\x7f\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))*(([ \t]*\r\n)?[ \t]+)?")#(([a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.)+([a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.?$/i;
if (pattern.test(email)) {
return true;
}
else {
return false;
}
};
Native method:
$("#myform").validate({
// options...
});
$.validator.methods.email = function( value, element ) {
return this.optional( element ) || /[a-z0-9._%+-]+#[a-z0-9.-]+\.[a-z]{2,4}/.test( value );
}
