how to get a particular cell value from dynamic table using javascript

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.

Rather than querying the DOM to extract data, have you considered returning the data from the server in an alternate form (eg. JSON)? Trying to extract tabular data out of a table sounds like bad design to me. — Flash

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
