jQuery .load() function

I'm generating table rows "N" times. If the user clicks "add row" buttons, I'm adding rows 开发者_Go百科in the table.

So, I need to load one external file in one TD. How can I load an external page by class and not ID?

For example

$('.classname').load('ajax/help.html');

When you generate the td, you should have a reference (or be able to get one) and either load the file then. If you want to load the file later, give each td a generated, unique ID and then link a button or whatever to that td. If your scenario is different, amend your question and ill update my answer.
