Removing all <tr> from a page using JQuery

I have a table with multiple <tr>. Some of them has set class on them.

I have <tr> with no class, with class="Failure" and with class="Error" (it's a JUnit html report).

I want to put a button on the page and after click on it to remove all 开发者_Python百科tr with the defined class on them (Failure and Error).

I have tryed something like this:

$("tr").remove(":contains('Failure')");

Thanks

If you mean with class Failure or Error, do this:

$("tr.Failure,tr.Error").remove();   // remove those with either

If you mean with both classes:

$("tr.Failure.Error").remove();   // remove those with both

For both of these, you can move the selector to the .remove() as you had it:

$("tr").remove(".Failure,.Error");  // remove those with either

or:

$("tr").remove(".Failure.Error");  // remove those with both

jQuery makes selecting elements by a class name very easy with element.class-name syntax. Just select the <tr> elements with the class you want, and remove them:

$('tr.Failure,tr.Error').remove();

The :contains selector doesn't match class names, only the text within the element.

Suggest you read up on your jQuery selectors.

Should look like:

$('tr.Failure, tr.Error').remove();

These guys are correct dude, if you wanted it with a button:

$('.button-class').click(function() {
    $('tr.Failure, tr.Error').remove();
    return false;
});

Also if you wanted to remove the ones without a class:

$('.button-class').click(function() {
    $('tr').each(function() {
        if ($(this).hasClass('Error') || $(this).hasClass('Failure'))
        {
        }
        else
        {
            $(this).remove();
        }
    });
});

('.button-class').click(function() 
{
 $('tr').each(function() 
 { 
  if(!$(this).is('.Failure,.Error'))
     $(this).remove();
 });
});
