Is there a way to combine these two similar functions into one in order to compress the JavaScript code? They both serve the same purpose but target different CSS classes. The goal is to highlight different images when hovering over specific list items - each list item corresponds to a different image.
$(".class1").mouseenter(function () {
$(".class2").addClass("highlight");
});
$(".class3").mouseenter(function () {
$(".class4").addClass("highlight");
});
data-* attribute to save the selector of the element where the class highlight should be included.data attribute to execute operations on it.Javascript:
$('.customClass').mouseenter(function() {
$($(this).data('target')).addClass('highlight');
});
Also, include the data-target attribute in your HTML code.
<div data-target=".element2" class="element1 customClass">Lorem</div>
<!-- ^^^^^^^^^^^^^^^^^^^ ^^^^^^^ -->
<div data-target=".element3" class="element2 customClass">Ipsum</div>
If you're looking for a solution, consider the snippet below; however, it might be beneficial to review your CSS hierarchy as recommended by @Tushar!
[['.item1', '.item2'], ['.item3', '.item4']].forEach(function(item) {
$(item[0]).hover(function(event) {
$(item[1]).addClass("active");
});
});
Building on the solution provided by @Tushar, you can easily assign multiple class attributes to an element using a comma-separated list like this:
Simply add a custom data-* attribute (where * represents any value) such as to to your elements as shown below:
<div data-to=".class2" class="class1">First Class</div>
<div data-to=".class3" class="class2">Second Class</div>
Then, with JavaScript:
$(".class1,.class2").mouseenter(function(){
$($(this).data('to')).addClass("highlight");
});
