Jquery search for brackets?

[rockinaway]

I have a bit of text as follows:

 

'this is my text. I want to (change this).'

 

Basically I want to search this var for brackets and then alter the information inside the brackets and finally output the new var.

 

I've been trying to use regex, but I'm not very good with the expressions :/

 

How would I do this?

Any help?

Yes, I think you would need to use regex and javascripts replace function.

 

Without testing I think it would go something along these lines:

 

var inputText = 'this is my text. I want to (change this).';
var outputText = inputText.replace(/\([^)]*?\)/g, "(new variable)");

 

Hope this helps,

Joe

Okay, thanks. How would I search the string first though? And then if the brackets are there, replace the content?

Use the javascript match to search for brackets, and only execute the replace if they are found. Something along the lines of

 

var inputText = 'this is my text. I want to (change this).';
if(inputText.match(/\([^)]*?\)/g))
   {
        var outputText = inputText.replace(/\([^)]*?\)/g, "(new variable)");
   }
else
   {
       alert('No brackets found');
   }
