My HTML code includes the following 3 elements:
<span class="a b"></span>
<span class="a"></span>
<span class="a b"></span>
I am trying to select the element that only has the class "a".
When I use $("span.a"), it selects all three elements.
Furthermore, I need to perform this selection within a for loop because it determines other calculations.
Although it seems like a simple problem, I am struggling to find a solution.
Choose the element based on its class attribute:
$("span[class='a']")
An alternative approach to @dfsq
$('.a:not(.b)')
Selecting all elements with the class a except those with class b. This method can also be used in standard CSS selectors.
.a:not(.b) {
color: red;
}
If you specifically want only elements with the class a and nothing else, dfsq's solution is perfect. However, if you require more flexibility with different combinations of classes, this approach may be more suitable.
This code snippet illustrates it:
.a:not(.b) {
color: red;
}<span class="a b">This span has class="a b"</span><br>
<span class="a">This one has only class="a"</span><br>
<span class="a b">This also has class="a b"</span><br>It's common knowledge that curl doesn't process JavaScript, it only fetches static HTML. This is why a simple curl command won't suffice for my needs. I'm not well-versed in PHP, still new to this field. From what I've gathered so ...
