CSS: Only apply the style to elements that have both specified classes, without affecting any elements with other classes

Here is the code snippet I'm using to inject a style that should be applied to a Div containing both the styles: .noindex and .ms-wpContentDivSpace

<script>
$(document).ready(function(){
$('.noindex, .ms-wpContentDivSpace')..css({
   overflow: auto,
   height : '150px'
});
});
</script>



<style> 
    .autoScrolListViewWP 
    {   
        HEIGHT: 150px; 
        OVERFLOW: auto 
    } 
</style>
<script> 
    $(document).ready
    (
        function()
        { 
            $('.noindex, .ms-wpContentDivSpace').addClass('autoScrolListViewWP');
        }
    );
</script>

However, I want the new CSS class autoScrolListViewWP to only be added to elements with the specific combination of classes: .noindex and .ms-wpContentDivSpace

The current script applies the style to any combination where these two classes exist. For example: .ms-WPBody, .noindex, and ms-wpContentDivSpace autoScrolListViewWP

So, my question is how can I identify only a specific combination of CSS classes?

Answer №1

To address this issue, one approach is to select all elements that contain specific classes and then loop through them to check if they have any additional classes. For example:

$('.noindex.ms-wpContentDivSpace').each(function(index, element) {
    var elementClasses = element.className.split(/\s+/);
    if (elementClasses.length === 2) { // ensure they only have these two classes
        $(element).addClass('autoScrolListViewWP');
        // alternatively element.className += ' autoScrolListViewWP'; (not fully tested)
    }
});

Answer №2

Here is an updated version of my code:

$("[class*='.noindex .ms-wpContentDivSpace']").addClass('autoScrolListViewWP');

I believe this solution should now be effective.

Update: The code is working, you can check out the example here: JsFiddle

Answer №3

attempt

$('.noindex.ms-wpContentDivSpace').addClass('autoScrolListViewWP');

this is the common css command to activate styling for an element with both classes

Answer №4

To implement this change, simply remove the space.

$('.noindex.ms-wpContentDivSpace').addClass('autoScrolListViewWP');

This code snippet will apply a class specifically to an element that has both the classes noindex and ms-ContentDivSpace.

Indeed, jQuery proves to be quite intelligent, functioning similarly to CSS.

Note:

Upon further inspection, if your goal is to target elements with those two classes exclusively (without any additional classes), the process becomes slightly more complex.

If you can pinpoint the one class you want to exclude, consider using this method for simplicity and efficiency:

$('.noindex.ms-wpContentDivSpace').not('.theClassYouDontWant').addClass('autoScrolListViewWP');

Answer №5

When you use jQuery,

$('.noindex, .ms-wpContentDivSpace')..css({

it targets each element with the class .noindex AND each element with the class .ms-wpContentDivSpace

$('.noindex.ms-wpContentDivSpace')..css({

while using $('.noindex.ms-wpContentDivSpace') targets elements that have both the classes .noindex AND .ms-wpContentDivSpace
