how to get a table value that inside an iframe

I am trying to get values from a table that lives inside an iframe using jquery but so far with no luck.

i have tried this code:

$('#childframe').contents().bind("dblclick", function() {
var code = $('#childframe').contents().find('.priceName').text();
alert(code);
return false; }):

but i am getting the text of the entire td for that column. because i am using gridview sap.net control i can't set the ID for that td and I am forced to define the CssClass to "pric开发者_JAVA技巧eName".

"childframe" is the ID for my iframe.

This should get you the text for the element that is double clicked:

$('#childframe').contents().bind("dblclick", function() {
    alert($(this).text());
});

Here's a working example: http://jsfiddle.net/K9P9q/30/

EDIT

If you're having a difficult time getting this to work, here's another suggestion (this assumes that you control that page being loaded in the iframe).

1. Do your click binding in the iframe itself. This should simplify the jquery binding code.
2. In your click handler function within the iframe, invoke a function on the parent and pass the text of the selected TD to the parent. Example below.

jQuery inside iframe

$('#[tableIdHere]').bind("dblclick", function() {
    parent.HandleTdDoubleClick($(this).text());
});

Hander inside parent

function HandleTdDoubleClick(txt)
{
    alert(txt);
}
