Question

OK, this is an embarrassingly simple question. Why doesn’t the following jQuery example work? Obviously it is supposed to change the ‘a’ in the table to ‘hello’.

HTML code:

    <table id='table1'>
      <tr>
          <td>a</td>
          <td>b</td>
      </tr>
    </table>​

JavaScript (JQuery) code:

    $("#table1 td:contains('a')").innerHTML="hello";

Answer 1

use the html function like this

 $("#table1 td:contains('a')").html("hallo");

if you want use innerHTML (is a DOM method, not a Jquery Method), you have to select the DOMElement first.

jQuery(document).ready(function(){
    $("#table1 td:contains('a')").each(function(){
    jQuery(this)[0].innerHTML = "Hallo";
    });
});
