Please find the below sample code,

</cfif>

<textarea id="#myName#"

name="#myName#"

rows="#local.fields[myName].rows#"

cols="#local.fields[myName].cols#"

onkeydown="maxlength#myName#(this,'#local.fields[myName].MaxLength#');maxlength1#myName#(this);"

onkeyup="maxlength#myName#(this,'#local.fields[myName].MaxLength#');maxlength1#FmyName#(this);"

>#IIF(len(local.fields[myName].value), DE(URLDecode(local.fields[myName].value)), DE(local.fields[myName].DefaultValue))#</textarea>

</cfcase>

<pre>#IIF(len(local.fields[myName].value), DE(URLDecode(local.fields[myName].value)), DE(local.fields[myName].DefaultValue))#</pre>

</cfif>

</cfdefaultcase>

</cfswitch>

function maxlength#myName#(textarea,maxLength){

var mainString = textarea.value;

var len = mainString.length;

if (len >= maxLength) {

textarea.value = textarea.value.substr(0, maxLength);

return false;

}

}//end maxlength

function maxlength1#myName#(textarea){

str = textarea.value;

newStr = str.replace(/[&#]/g, "" ); // error 'Invalid CFML construct found on line' , occurs here

if(isNaN(newStr)){

newStr = "";

} else{

}

textarea.value = newStr;

}//end maxlength

</script>

</cfoutput>

My goal is : I should not be able to enter special characters '#' and '&' in the textarea. I thought the following piece of code would stop me from entering # and & in the text area :

newStr = str.replace(/[&#]/g, "" );

However I'm getting error ,

Invalid CFML construct found on line newStr = str.replace(/[&#]/g, "" );

Please help me.

Thanks,

Vishnu

Vishnu, you have a couple of problems there. First the compilation error is because you're passing in as the first argument some characters (the regex) that form a string--and a string in cfml must be enclosed in quotes.

More important, though, the cfml replace expression doesn't work with regular expressions. (Did you find some resource suggesting it would? Where is it?)

Instead, consider the rereplace and rereplacenocase functions. See the docs starting at https://helpx.adobe.com/coldfusion/cfml-reference/coldfusion-functions/functions-m-r/replace.html. See especially the first example, which you can also run online at the Cffiddle site. Then see still more on the topic at https://helpx.adobe.com/coldfusion/developing-applications/the-cfml-programming-language/using-regular-expressions-in-functions.html

Let us know how things go.

# is reserved for variable use in CF. To use it in a regular expression in a function like you are, I believe you need to use a double-hash: ## So,

newStr = str.replace(/[&##]/g, "" );
