如何使用javascript从动态表中获取特定的单元格值

Question

I have a table showing records from database. There is a dropdown for selecting a particular user in each row. On change, it should show the corresponding values of the new user.

When I'm selecting a particular user from the dropdown, it should match the col1 and col2 value with the user selected and return col3 value. What I want is to get the col1 and col2 value of that particular row. How can I do it ? Please help me.

You want to use live('click', function() . This will apply on dynamically created elements.

For example, you may try something like;

$('#your_table_id .some_class_in_a_row_to_click').live('click', function(){
    $(this).siblings().each(function(){
      var column = $(this).find('.some_class_for_column_with_data');
      var data = column.text();
      alert(data);
    });
});

You may apply this on a table having some columns. Clicking on some column with class some_class_in_a_row_to_click will alert text on another column in that row having class some_class_for_column_with_data
