Populating text input in Coldfusion - coldfusion

I'm trying to do the following (amongst many other attempts), and have validated that #myVar# holds data and is current in the scope, but nothing works. Any ideas how to populate a text input in Coldfusion? Many thanks in advance!
<cfoutput>#myVar#</cfoutput>
<script>document.getElementById("text1").value = #myVar# </script>

The easiest way is with the value attribute of an input tag.
<form>
<input name "fred" value="flinstone">
etc
If you want to populate it dynamically, use cfoutput.
<cfset myVar = "flinstone">
<cfoutput>
<form>
<input name "fred" value="#myVar#">
etc
or is that not the question?

Your closing </cfoutput> is too early, where you're trying to output the value inside your javascript should also be wrapped in the cfoutput.
<cfoutput>
#myVar#
<script>document.getElementById("text1").value = "#myVar#";</script>
</cfoutput>

Is your value a string or an integer? If its a string you will need wrap the value in quotes.
Additionally you will want to use the jsStringFormat() function to ensure any quotes are escaped.
<script>document.getElementById("text1").value = "#jsStringFormat(myVar)#"; </script>

How to remove the attributes in div tag without class,id and style rest of attributes need to be delete using coldfusion?

I have attribute like this.
Example:
<div class="issue-document" id="assr_0335-5985_1991_num_76_1_1619" itemprop="hasPart" itemscope="" itemtype="https://facebook.com>
<cfset mystring = 'This is some text. It is true that <div class="issue-document" id="assr_0335-5985_1991_num_76_1_1619" itemprop="hasPart" itemscope="" itemtype="https://facebook.com">Harry Potter</div> is a good, but is better'>
<cfset MyReplace = ReReplaceNoCase(mystring,"<div [^>]*>","","ALL")>
<cfoutput><pre>Original string: #mystring#
Without link: #myreplace#</pre></cfoutput>
I need to remove only itemscope and itemprop like this rest of the attribute like id,class, style i don't want to remove using coldfusion in regular expression. Can any one please help to find the solution.
<cfset myReplace = reReplaceNoCase(mystring, '\b(itemscope|itemprop)="[^"]*"', "", "all")) />

Trying to dynamically output form fields returns URL values

If there is a better way to go about this (which is quite likely), please let me know how to go about it.
I'm working on some code that is supposed to dynamically set the form variables as regular variables so that we can be lazy and not have to refer to the variable with form.somevariable name.
That part works perfectly. Until I start testing for URL conflicts in which a URL variable has the same name. For instance. . .
I have a form that passes two variables; FirstName and LastName. If I hit the page, the form shows up, I input a first and last name and click submit. The code works perfectly.
However, if I have URL variables with the same names, the code reports the url variable values instead of the form values.
Some sample values;
url.FirstName = Joe
url.LastName = Black
form.FirstName = Steve
form.LastName = White
My code that exposes the form variable will correctly find the form field names, but then when I 'evaluate' the value of the given form field, it will return the value of the URL variable of the same name rather than the form variable.
What I am really wanting (as I described briefly up above) is to have code that automatically converts client, URL and Form variables into 'regular variables' so that you don't have to write lots of extra code grabbing them later on. Frameworks like CFWHEELS and ColdBox do this by default, but at the company I work out, we aren't using any of them. I need it to expose the URL variables, but give presidence to form variables if they have the same name, because they are likely to be intended to do an update or such.
The code follows Feel free to ignore the code for the URL and client variables if you wish as they don't directly affect how the form code works, I have tested with them commented out and I get the same result. I provided all of it to give a more complete idea of what I have been toying with so far. Please note that I don't normally use 'evaluate'. There is probably a better way to go, but I don't know what it is.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++
First Name
Last Name
URL variables:
<cfloop index="i" list="#paramsurl#">
<cfset myDynVar = Evaluate(i)>
<!--- Let's output the dynamically created variable as a test --->
#i# = #myDynVar#<br />
</cfloop>
<cfoutput>
<b>Field Names:</b> #Form.FieldNames#
<p>
<b>Field Values:</b><br>
<cfloop INDEX="TheField" list="#Form.FieldNames#">
#TheField# = #Evaluate(TheField)#<br>
<cfset TheField = Evaluate(TheField)>
</cfloop>
</p>
Lets try and output the two form fields without using the "form." notation<br>
FirstName : #FirstName# <br />
LastName : #LastName#
</cfoutput>
The client variables currently available are:
<cfset nVarCounter = 1>
<cfloop list="#GetClientVariablesList()#" index="whichClientVar">
#whichClientVar# : #client[whichClientVar]#<br />
<cfset whichClientVar = Evaluate(whichClientVar)>
</cfloop>
You should always scope your variables. When you use evaluate it runs through the scope order and it pulls the values out of the url scope before it gets to the form scope
You can use associative array notation to pull the data (as seen below).
<cfoutput>
<b>Field Names:</b> #Form.FieldNames#
<p>
<b>Field Values:</b><br>
<cfloop INDEX="TheField" list="#Form.FieldNames#">
#TheField# = #form[TheField]#<br><!--- specify form scope --->
<cfset myField = structKeyExists(url,TheField) ? url.TheField : form.TheField>
</cfloop>
</p>
</cfoutput>
You can 'copy' the values from form scope and url scope into the variables scope by using structAppend().
structAppend( variables, form, true );
structAppend( variables, url, false );
In the first line, any element of the form scope is copied to the variables scope and if a variable already exists with the same name in variables scope, it will overwrite that value with the value from the form scope.
In the second line, elements form URL scope are copied to variables scope but if a variable already exists in the variables scope, it is NOT overwritten.
You can do this for ANY scope and any other ColdFusion structure. You can also reorder them so that one scope has precedence over the others.
In CF 10 or Railo 4, you could use the defaults() function of the Underscore.cfc library to succinctly accomplish what you're trying to do. Example:
// instantiate Underscore library
_ = new Underscore();
// copy values from form and url scopes into the variables scope
_.defaults(variables, form, url);
This function "fills in" any undefined values in the first struct to the values in the subsequent structs. It works from left to right, so in this example it gives precedence to values in form over the values in url.
Disclaimer: I wrote the Underscore.cfc library.
Please refer to the following Adobe documentation for order of precedence:
http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec09af4-7fdf.html
If you want to reverse this precedence for some reason you should be able to just set all of your FORM fields into the variables scope...
Maybe something like ...
<cfloop collection=#form# item="varName">
<cfset SetVariable("variables.#varName#", evaluate("FORM." & varName))>
</cfloop>
Thanks for all of the great ideas.
Following is what I ended up going with.
<cfset scopes = "url,client,form">
<cfloop list="#scopes#" index="i">
<cfloop list="#structKeyList( evaluate( i ) )#" index="j">
<cfset structInsert( VARIABLES, j, evaluate( i & '["' & j & '"]' ), true ) />
</cfloop>
</cfloop>
<cfoutput>
Lets try and output the two form fields without using the "form." notation and make sure that the URL variables are NOT over writing the Form ones<br>
FirstName : #FirstName# <br />
LastName : #LastName#<br />
</cfoutput>
<cfdump var="#VARIABLES#" abort="1" label="Combined Variables Scope stuff" />

is there a way to add some spacing to cfmail type=text emails in Coldfusion when using variables only?

I'm a little in awe on how my first Cfmails are looking.
Problem is, I'm using variables for both text and content and I would still like to have some sort of spacing.
For example, if I have:
<cfprocessingdirective suppresswhitespace="No">
<cfmail
TO="#Local.User.email#"
FROM="..."
SERVER="..."
USERNAME="..."
PASSWORD="..."
WRAPTEXT="80"
SUBJECT="#tx_automailer_register_subject# - #Local.User.Comp#">
#tx_automailer_default_hello#
#tx_automailer_register_info#
#tx_automailer_register_iln#: #Local.User.iln#
#tx_firma#: #Local.User.firma#
#tx_ansprechpartner#: #Local.User.ansprechpartner#
#tx_adresse#: #Local.User.adresse#
#tx_plz#: #Local.User.plz#
#tx_ort#: #Local.User.ort#
...
The only place this looks nice is my cfc :-) In the mail itself everything is going bazooka.
Question:
Is there a way to space this? I have also tried to space according to length of variables, but this also does not really do any good and I'm not really keen on doing math for this...
Thanks for help!
The only option may be to post process the content. Build up the pretty content in a cfsavecontent, then run through cleanup function.
<cfprocessingdirective suppresswhitespace="No">
<cfsavecontent variable="message">
#tx_automailer_default_hello#
#tx_automailer_register_info#
#tx_automailer_register_iln#: #Local.User.iln#
#tx_firma#: #Local.User.firma#
#tx_ansprechpartner#: #Local.User.ansprechpartner#
#tx_adresse#: #Local.User.adresse#
#tx_plz#: #Local.User.plz#
#tx_ort#: #Local.User.ort#
</cfsavecontent>
<cfmail
TO="#Local.User.email#"
FROM="..."
SERVER="..."
USERNAME="..."
PASSWORD="..."
WRAPTEXT="80"
SUBJECT="#tx_automailer_register_subject# - #Local.User.Comp#"
>#cleanupTextMessage(message)#</cfmail>
<cffunction name="cleanupTextMessage" output="false">
<cfargument name="content" />
<!--- remove whitespace at beginning of each line --->
<cfset arguments.content = reReplace(arguments.content, "^\s+", "", "all") />
<!--- replace any multiple whitespace characters with one space --->
<cfset arguments.content = reReplace(arguments.content, "\s+", " ", "all") />
<cfreturn arguments.content />
</cffunction>
You might actually be able to nest the cfsavecontent inside cfmail, or create a custom tag that does savecontent and function actions.
Note: I was answering under the assumption the question was "how to make code look good without affecting the resulting text message". If you were trying to do something different with the resulting text output let me know.
You can use HTML To do it by adding the TYPE="html" to your cfmail attributes. Then put in a "pre" tag if you want that sysprint type look. as in
<pre>
#tx_automailer_default_hello#
#tx_automailer_register_info#
....
</pre>
Or you could add a table as in:
<table
<tr>
<td>#tx_automailer_default_hello#</td>
</tr>
<tr><td>
#tx_automailer_register_info#
</td>
If you want to stick with plain text you need to make sure you have tabs/spaces counted correctly and that none of your lines is longer than 80 chars (or they will wrap..without a beat too).
If you're set on plaintext email and are confident that the recipient will be using a fixed-width font, you can use lJustify() to align your text and pad with spaces.
Left justifies characters in a string of a specified length.
#lJustify(tx_automailer_register_iln & ":",32)# #lJustify(Local.User.iln,25)#
#lJustify(tx_firma & ":",32)# #lJustify(Local.User.firma,25)#
#lJustify(tx_ansprechpartner & ":",32)# #lJustify(Local.User.ansprechpartner,25)#
#lJustify(tx_adresse & ":",32)# #lJustify(Local.User.adresse,25)#
#lJustify(tx_plz & ":",32)# #lJustify(Local.User.plz,25)#
#lJustify(tx_ort & ":",32)# #lJustify(Local.User.ort,25)#

How to determine if a full name has a space in it?

I have a field that a user can input first and last name to fill out my form. Sometimes, users put on their first name and that results in empty fields in my database. PLEASE keep in mind that I cannot change this method completely because this form is part of a bigger project and it is being used by other websites of my company.
This is the part of the code that i need the validation around it. I already have a validation that ensures that the filed is not empty but I need on more to ensure that the field has two items in it separated by space.
<input name="fullname" class="fullname" type="text" value="#fullname#" maxlength="150"/>
<cfif fullname eq '' and check2 eq 'check2'>
<br /><span style="color:red">*you must enter your full name</span></cfif>
The check2 eq 'check2' is checking if the form was submitted already to ensure a user submitting their data twice.
I thought of using regular expressions to do that but unfortunately I am not very familiar with how to use regx in CF9 and the documentation online through me off a bit.
I was also thinking to use "Find" or "FindOneOF", any thoughts on that?
Also, I am trying to avoid using JQ,JS etc, so please try to keep your suggestions based on CF code IF possible.
Any help or different suggestions on how to tackle this issue will be very appreciated.
No regex is needed for this. A slightly simpler solution:
<cfset form.fullname = "Dave " />
<cfif listLen(form.fullname," ") GT 1> <!--- space-delimited list, no need for trimming or anything --->
<!--- name has more than one 'piece' -- is good --->
<cfelse>
<!--- name has only one 'piece' -- bad --->
</cfif>
You could do something like this for server side validation:
<cfscript>
TheString = "ronger ddd";
TheString = trim(TheString); // get rid of beginning and ending spaces
SpaceAt = reFind(" ", TheString); // find the index of a space
// no space found -- one word
if (SpaceAt == 0) {
FullNameHasSpace = false;
// at least one space was found -- more than one word
} else {
FullNameHasSpace = true;
}
</cfscript>
<cfoutput>
<input type="input" value="#TheString#">
<cfif FullNameHasSpace eq true>
<p>found space at position #SpaceAt#</p>
<p>Your data is good.</p>
<cfelse>
<p>Did not find a space.</p>
<p>Your data is bad.</p>
</cfif>
</cfoutput>

ColdFusion, Setting a POST variable

Im editing my first ColdFusion script .... I have a form which has <input type="hidden" name="name" value="1">.
On the processing page i want to take that value and set it as a POST variable so i can send it onto another page.
I know how to do it in PHP, like so
$_POST['somename'] = $_POST['name']
How would i do that in CF?
Following the idiom in your php code, you can do something like this:
<cfset form['somename'] = form['name']>
...or, if in cfscript:
form['somename'] = form['name'];
If you're concerned about the existence of the variable, you can precede the assignment with <cfparam>:
<cfparam name="form.name" default=""><!--- assuming blank ok as default --->
<cfset form['somename'] = form['name']>
...or in script:
param name='form.name' default='';
form['somename'] = form['name'];
Of course you can also wrap the assignment in a conditional:
if( structkeyexists(form,'name') ){
form.somename = form.name; // dot notation alternative to bracket syntax
}
This all begs the question of what exactly you're trying to achieve with this approach.
The ColdFusion syntax is similar. "Post" variables are available in the system structure FORM, and "Get" variables in the system structure URL. Like in PHP, values can be accessed using associative array notation. You can also use dot notation (for valid field names)
<cfset otherVariable = FORM["variableName"] >
<cfset otherVariable = FORM.variableName >
i want to take that value and set it
as a POST variable so i can send it
onto another page.
I am not quite sure what you mean there. Typically, you do not need to reassign FORM or URL values. You simply reference the variable in your code.
<cfoutput>
Go To Other Page
</cfoutput>
You can try this by checking if the post variable is set and then storing it with scope of FORM.
<cfif isdefined ("FORM.name")>
<cfset FORM.somename="#FORM.name#">
</cfif>
