how to manipulate strings in jQuery (especially, finding sub-string in a string)

Question

let's say, for instance, I have this

<h2>I don't love Programming</h2>

I'd like to remove 'don't' from the text inside the h2 tag.

So far, I've done this

var content = $(h2).text();

That's allow me to get the text 'I don't love Programming'. But I need a way to locate don't and replace it by something else or simply remove it.

Thanks for helping

You can use the replace function:

var content = $(h2).text().replace("don't", "");

To come up with:

I love Programming

If you want to remove all instances of a string from given string, you can use regex with /g modifier:

var content = $(h2).text().replace(/don't/g, '');

@Caspar: jQuery is also javascript at its core. The replace function is what you need to use there :)

I agree completely with your answer, replace however is not a jQuery function. Just as a sidenote: the answer has just partially something to do with jQuery.
