Struggling a bit with selecting only the first child within a li tag that contains a link.
HTML:
<ul class="dropdown-menu" role="menu" aria-expanded="true">
<li role="presentation" class="dropdown-header">Label</li>
<li><a href="#">Choose Me</a> </li>
</ul>
JavaScript:
dropdown.find('.dropdown-menu li:first-child a').focus();
In this scenario, it is unable to select beyond the list item labeled "Label".
To target a specific element in jQuery, you can utilize the eq method.
The
eqmethod reduces the set of matched elements to the one at the specified index.
$('body').find('.dropdown-menu li a').eq(0).css('color','red');<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="dropdown-menu" role="menu" aria-expanded="true>
<li role="presentation" class="dropdown-header">Label 1</li>
<li role="presentation" class="dropdown-header">Label 2</li>
<li role="presentation" class="dropdown-header">Label 3</li>
<li><a href="#">Select Me</a> </li>
</ul>Another approach is to use the :first pseudo-selector.
The :first selector narrows down the set of matched elements to the first one in the selection.
$('body').find('.dropdown-menu li a:first').css('color','red');
$('body').find('.dropdown-menu li a:first').css('color','red');<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="dropdown-menu" role="menu" aria-expanded="true>
<li role="presentation" class="dropdown-header">Label</li>
<li><a href="#">Select Me</a> </li>
</ul>Additionally, you can use the $.each method to find and modify the color of the first li element that contains an anchor tag.
$('ul li').each(function(){
if($(this).find('a').length>0){
$(this).find('a').css('color','red');
return false;
}
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="dropdown-menu" role="menu" aria-expanded="true>
<li role="presentation" class="dropdown-header">Label 1</li>
<li role="presentation" class="dropdown-header">Label 2</li>
<li role="presentation" class="dropdown-header">Label 3</li>
<li><a href="#">Select Me</a> </li>
</ul>How about using
