A guide on using jQuery to cycle through every row of every table on an HTML page

I am trying to figure out the correct syntax for nesting two loops within each other in jQuery. The first loop should iterate over each table in an HTML page that does not have any IDs or classes, while the second loop should go through each table row of the currently targeted table by the first loop.

My current jQuery code is not working and I suspect it may be due to incorrect syntax. Here is what I have:

$(document).ready(function(){
    $('table').each(function(){
        $(this + ' tr').each(function{
            // Change style of this table row
        });
    });
 });

Answer №1

Here is a method to target specific elements within a table using jQuery:

$(document).ready(function(){
    $('table.rep').each(function(){
        $('tr', this).each(function{
             // change style of this tr
        });
    });
});

Another way to achieve the same result is by using the find method:

$(document).ready(function(){
    $('table.rep').each(function(){
        $(this).find('tr').each(function{
             // change style of this tr
        });
    });
});

If you only need to loop through all table rows without nesting loops, you can simply do the following:

$('table tr').each(function(){
    // change tr style
});

Answer №2

Alternatively:

$('table.rep tr').each(function(){
    ...        
});

Answer №3

<script>
    $(document).ready(function () {
        $('table.rep').each(function () {
            $(this).find('tr').each(function () {
            // Implement your desired functionality here
            });
        });
    });

 </script>
