CSS背景颜色和文本随jquery / javascript改变

Question

Having trouble with a piece of code to change both the background color and text color when a link is clicked.....

<div id="main_nav">
    <ul class="navigation">
        <li class="tab1"><a href="javascript:void(0);">My Account</a></li>
        <li class="tab1"><a href="javascript:void(0);">Available Times</a></li>
        <li class="tab1"><a href="javascript:void(0);">Completed Jobs</a></li>
        <li class="tab1"><a href="javascript:void(0);">New Jobs [<span class="menu_count2"></span>]</a></li>
        <li class="tab1"><a href="javascript:void(0);">Todays Jobs [<span class="menu_count"></span>]</a></li>
    </ul>
</div>

This is the jquery....

$(document).on('click', '.tab1', function(){
    $('.tab1').css({'background-color' : '#5B1762'});
    $('.tab1 a').css({'color' : '#fff'});
    $(this, '.tab1').css({'background-color': '#ccc'});
    $(this, '.tab1 a').css({'color': 'red'});
});

This changes the background color but the text remains white as in the css file.

Answer 1

You are coding $(context, selector) instead of the $(selector, context) , change:

$(this, '.tab1').css({'background-color': '#ccc'});
$(this, '.tab1 a').css({'color': 'red'});

To:

$(this).css({'background-color': '#ccc'});
$('a', this).css({'color': 'red'});

Answer 2

Could be done that way too:

$('.tab1').click( function(){
    $('.tab1').css({'background-color' : '#5B1762'}).find('a').css({'color' : '#fff'});
    $(this).css({'background-color': '#ccc'}).find('a').css({'color': 'red'});
});
