Is there a CSS equivalent of .live() in jQuery?

Is it possible to apply CSS styles to dynamically created elements?

Let's take a look at a basic example of what I am trying to achieve:

$(document).ready(function() { 
    $('#container').html('<p id="hello">hello world</p>');
    // The code snippet below is not working as expected. 
    $('#hello').css("background-color", "#FFF");
});

I have this requirement because I want to add background colors to alternating rows in a dynamically generated table:

$("#results-table tr:even").css("background-color", "#FFF");

This jQuery line is specifically needed for dealing with IE8 and older versions, which do not support the use of `nth-child` CSS selectors.

Answer №1

It appears that your code is functioning correctly. Please ensure that you do not have multiple elements with the same ID.

Update: Check out your revised code without any duplicate IDs here: http://jsfiddle.net/FhTU7/

Final revision: Both your HTML background and element background are set to white.

Answer №2

Instead of directly applying the CSS properties, you can also opt to assign a class to the even rows.

$("#results-table tr:even").addClass("alt");

This code snippet includes CSS for setting the row colors and a separate styling for alternate rows.

<style type="text/css>
tr {
    background: #fff;
    color: #000;
}

tr.alt {
    background: #000;
    color: #fff;
}
</style>

Answer №3

To define the new element as a variable, you can do the following...

$(document).ready(function() { 
    var $newElem = $('<p id="greeting">Greetings to the world</p>');
        $newElem.css({
            backgroundColor: "#fff"
        });
        $('#container').append($newElem);
});

Another option is to use appendTo method like this...

$(document).ready(function() { 
    $('<p id="greeting">Greetings to the world</p>').appendTo('#container').css({
        backgroundColor: "#fff"
    });
});

Alternatively, if you create the elements correctly, you can apply the original CSS in the end like so...

$('#container').append('<p id="greeting">Greetings to the world</p>');
