Finding and replacing content between brackets with jQuery

Question

I have a requirement to place text between brackets using jQuery; the content will be updated once an action occurs e.g. search.

The structure is: -

<h2>Placeholder Text Placeholder Text Placeholder Text ()</h2>

Answer 1

You can use the indexOf method:

text = $("h2").text();
pos1 = text.indexOf("(");
pos2 = text.indexOf(")");
newText = text.substring(0, pos1 + 1) + myText + text.substring(pos2);

The above assumes that one and only one pair of brackets is to be found in the text.
