With the url string below, I need to find the value of the parameter named construction.
<cfset understand = "http://www.example.com/ops.cfm?id=code&construction=148&construction=150&Building=852&Building=665&Building=348&Building=619&Building=625&Building=626&_=1426353166006&action=SUBMIT">
<cfset understand2 = "http://www.example.com/ops.cfm?id=code&construction=AVENT+Construction+Site&construction=Signore+upper+constructions&Building=852&Building=665&Building=348&Building=619&Building=625&Building=626&_=1426353166006&action=SUBMIT">
I then want to check if the value is numeric or a string. I am doing this:
isDefined('understand') and isnumeric(understand)
But it always returns "NO".
Seems like a good case for REGEX, but that's not my strength. If you are always looking for the value of the same item (construction), you could take advantage of the underlying Java and use the STRING.split() method. Then use the Coldfusion val() function to see what you get. The following solution assumes that 0 is not a valid value. If it is then you have more work to do.
<cfscript>
target=understand;
//target=understand2; //uncomment to try the second values
token="construction=";
potentialValues = target.split(token); //creates an array of values using the token as a separator
for (item in potentialValues )
{
writeoutput(val(item) & "<br />"); //val will grab the numerical value and ignore everything that follows. No number will become 0
}
</cfscript>
Try this:
constructionIsAt = find(understand, "construction");
characterAfterConstruction = mid(understand, constructionIsAt + 13, 1);
if isNumeric(characterAfterConstruction) {
code for numeric
}
else {
code for non numeric
}

I am trying to use multiple characters as the delimeter in ColdFusion list like ,( comma and blank) but it ignores the blank.
I then tried to use:
<cfset title = listappend( title, a[ idx ].title, "#Chr(44)##Chr(32)#" ) />
But it also ignores the blank and without blanks the list items to diffucult to read.
Any ideas?
With ListAppend you can only use one delimiter. As the docs say for the delimiters parameter:
If this parameter contains more than one character, ColdFusion uses only the first character.
I'm not sure what a[ idx ].title contains or exactly what the expected result is (would be better if you gave a complete example), but I think something like this will do what you want or at least get you started:
<cfscript>
a = [
{"title"="One"},
{"title"="Two"},
{"title"="Three"}
];
result = "";
for (el in a) {
result &= el.title & ", ";
}
writeDump(result);
</cfscript>
I think there's a fundamental flaw in your approach here. The list delimiter is part of the structure of the data, whereas you are also trying to use it for "decoration" when you come to output the data from the list. Whilst often conveniently this'll work, it's kinda conflating two ideas.
What you should do is eschew the use of lists as a data structure completely, as they're a bit crap. Use an array for storing the data, and then deal with rendering it as a separate issue: write a render function which puts whatever separator you want in your display between each element.
function displayArrayAsList(array, separator){
var list = "";
for (var element in array){
list &= (len(list) ? separator : "");
list &= element;
}
return list;
}
writeOutput(displayAsList(["tahi", "rua", "toru", "wha"], ", "));
tahi, rua, toru, wha
Use a two step process. Step 1 - create your comma delimited list. Step 2
yourList = replace(yourList, ",", ", ", "all");
I have a code where the values are coming as:
a,b,c from database..
now i want to remove c from the string based upon condition, c can be at any place, 1st, last or middle.
i am using replace to do it like this:
<cfset answer = Replace('a,b,c','c','','all')>
This works but it leaves a trailing comma at the end or at the start or 2 commas in middle breaking the whole string, what can be my approach here
<cfscript>
input = 'a,b,c';
foundAt = listFind(input, 'c');
answer = foundAt ? listDeleteAt(input, foundAt) : input;
writeOutput(answer);
</cfscript>
Run this code LIVE on TryCF.com
See: List functions
OR use REReplace(). The solution was just one google search away: Regex for removing an item from a comma-separated string?
function listRemoveAll(list, item) {
return REReplace(list, "\b#item#\b,|,\b#item#\b$", "", "all");
}
I was trying to have the value as 456,987,214.
But For me it is coming like without comma.
Here is my code, Did i mistake anything
const string price = "^\\d{3},\\d{3},\\d{3}$";
string pricelist = query.price.ToString();
string price1 = "";
if (System.Text.RegularExpressions.Regex.IsMatch(pricelist.ToString(), price))
{
price1 = query.price.ToString();
}
I noticed it, it is number what you intended to format why not using angular built-in formatting feature like: {{price | number}}
Online Demo
If you want to format this with C# then you can format it using .Net built-in formatters like:
double value = 1234567890;
Console.WriteLine(value.ToString("#,#", CultureInfo.InvariantCulture));
// outputs 1,234,567,890
Try this simple Method:
Just pass your value like this ,
double value = double.Parse(query.price.ToString());
string price1= value.ToString("#,#", CultureInfo.InvariantCulture);
Output will be like 123,456,789
Try this simple method: Just pass your value like this, then you will get the output as you want.
double value = double.Parse(query.price.ToString());
string price1= value.ToString("#,#", CultureInfo.InvariantCulture);
Output will be like 123,456,789
I would like to convert the following C++ method to a regular expression match/replace string pair. Is it possible to do this in a single pass, i.e. with a single call to a regex replace method? (such as this one)
std::string f(std::string value)
{
if (value.length() < 3)
{
value = std::string("0") + value;
}
value = value.substr(0, value.length() - 2) + std::string(".") + value.substr(value.length() - 2, 2);
return value;
}
The input is a string of one or more digits.
Some examples:
f("1234") = "12.34"
f("123") = "1.23"
f("12") = "0.12"
f("1") = ".01"
The only way I've been able to achieve this so far is by using 2 steps:
1. Apply a prefix of "00" to the input string.
2. Use the following regex match/replace pair:
Match: (0*)(\d+)(\d{2})
Replace: $2.$3
My question is, can this be done in a single "pass" by only calling the Regex replace method once and without prepending anything to the string beforehand.
I believe this isn't possible with a single expression/replacement, but I'd just like someone to confirm that (or otherwise provide a solution :) ).
I hope this will help. (Change a bit again) x3.
string a_="123456";
a_="14";
a_="9";
string a = regex_replace(a_,regex("(.*)(.{2})|()"),string("$1.$2."));
//a = regex_replace(regex_replace(a,regex("^"),string("00$1$2")),regex("(.+)(.{2})"),string("$1.$2"));
//a = regex_replace("00"+a,regex("(.+)(.{2})"),string("$1.$2"));
float i=atof(a.c_str());
if(!(i))//just go here for 0-9
{
i=atof((string("0.0")+a_).c_str());
}
cout<<i<<endl;
return 0;
I am using ColdFusion 9.0.1.
I am trying to test whether a user has provided a non alphanumeric value. If they have, I want to return false. I'm pretty sure I am close, but I keep getting an error:
Complex object types cannot be converted to simple values.
I've tried multiple ways of making this work, but I can't get it to work.
Specifically, I want to allow only a through z and 0 through 9. No spaces, or special characters.
Can you help me tweak this?
<cfscript>
LOCAL.Description = trim(left(ARGUMENTS.Description, 15));
if (len(LOCAL.Description) lte 4) {
return false;
} else if (reMatchNoCase("[^A-Za-z0-9_]", LOCAL.Description) neq "") {
return false;
} else {
return true;
</cfscript>

reMatchNoCase returns Array which cannot be compared to the string, use ArrayLen() on the result in order to find out if there any matches
There is actually another problem in your code. First line will produce an error if the length of the description is less than 15, which means that the first IF is obsolete since it will always be false.
reMatchNoCase("[^A-Za-z0-9_]", LOCAL.Description) neq ""
It is because ReMatchNoCase returns an array, not a simple string. Either check the array length, or better yet, use ReFindNoCase instead. It returns the position of the first match, or 0 if it was not found.
You can also try the following approach:
<cfscript>
local.description = trim(local.description);
return reFind("(?i)^[A-Z0-9_]{5,}$", local.description)?true:false;
</cfscript>
I'm late to the party but reFindNoCase is the optimal solution in 2021. Here's how I would handle the code in the original question:
// best practice not to have a local var name identical to an argument var
var myValue = trim( left( arguments.description, 15 ) );
// return false if myValue is less than 4 or has special characters
return(
!len( myValue ) lte 4 &&
!reFindNoCase( "[^a-z0-9]", myValue )
);
