how can i get only the cheque number(AA12GH56) not the other texts, here is my code:

HTML:

<p>your cheque number is :AA12GH56 <br /> your bank credit balance is :32,999</p>

Javascript:

$(document).ready(function(){
  $('p').click(function(){
    var cheque_no=$(this).text();
  });
});

You should use javascript's regular expressions if you can't modify the html. I recomend this page to learn: http://www.javascriptkit.com/javatutors/redev.shtml

If you can modify the html I would put the cheque number inside a span with a proper class name (or id):

<p>
  your cheque number is <span id="cheque-number">:AA12GH56</span> <br /> 
  your bank credit balance is :32,999
</p>

so the javascript would be:

$('p').click(function(){  var cheque_no=$(this).find("#cheque-number").text();  });  });

    You should modify your code so that he can still click anywhere on the `

    ` and still get just the `cheque-number`.

Either a regular expression or a precision .split is what you need. I'm a fan of the latter technique -- what it loses in brevity it makes up in clarity.

var cheque_no=$(this).text().split(':')[1].split('your')[0];
cheque_no = $.trim(cheque_no); // remove whitespace

  • @Chango I agree; I prefer your `span` approach. However, I assumed that OP couldn't modify the source HTML for some reason. – Blazemonger Dec 05 '11 at 14:42
