Hi guys. I am trying to do some real time validation, but because there are so many records, I am going to try and do a regex expression. Basically, I have an if statement which displays a tick if the condition is correct. What I need to do is have the expression check for the input in the following format
LOL - Laugh Out Loud
DWM - Dont Worry

So basically, the format should be 3 capital letters, followed by a space, hash, space, and then some other words. So I grab the input

var phase = $("input[name='phase']").val();

Then I need to try and get the regex expression

if(isValidExpression){
}

function isValidExpression(phase) {
      var pattern = new RegExp(??);
      return pattern.test(phase);
}

What would the regex for this format be?

Cheers

Nick

I tested this one over at Rubular (http://rubular.com - brilliant Regex testing site), and it seemed to do the job:

\A[A-Z]{3} - [A-Za-z]\z

Kool, didnt know about that site, will be helpful in the future. I have added it so its like

var pattern = new RegExp(\A[A-Z]{3} - [A-Za-z]\z);

But thats giving me a syntax error. I dont know if I need extra () somewhere?

I'm not sure exactly how the RegExp object is expecting to receive it, but IIRC you can simplify the process by just using forward-slashes and removing the new RegExp call altogether:

var pattern = /[A-Z]{3} - [A-Za-z]+/;

Also, the RegEx is modified a little from before. It wasn't working as a direct translation to Javascript (not sure if that was an error on my part, or a difference between Ruby and Javascript). It should work for you like this.

I recommend taking a poke around this tutorial for more information.
