My goal is to set the padding-right css property based on the width of a child element. Here's my approach:
Using jQuery
$('.parent_element').css('padding-right', $(this).children('.child_element').width() + 'px');
Here's the HTML structure:
<a href="#" class="parent_element"><i class="fa"></i> Example <span class="child_element">101</span></a>
However, this code doesn't apply the desired css to the parent element.
If you want to dynamically set the padding-right of an element based on its child elements, you can achieve this by using a function as the second argument in the jQuery .css() method.
$('.parent_element').css('padding-right', function () {
return $(this).children('.child_element').width() + 'px';
});
You can see an example of this implementation here.
this in this snippet of code will represent the value of this within the current scope, rather than the intended target of the .css method. In order to achieve the desired outcome, a new scope must be created. This can be accomplished by passing a function to the .css method that returns the desired value:
$('.parent_element').css('padding-right', function(){
return $(this).children('.child_element').width() + 'px'
});
