jQuery neglecting events of child elements

I am facing an issue with the following list structure:

  <ul id="menu">
            <li style="background-image:url('Images/X-AFH-Company-Office-Background.png')" id="office">
                <div >Company / Office</div>
                <img src="Images/Employee.png"  onmouseover="this.src='Images/Employee-Stroke.png'" onmouseout="this.src='Images/Employee.png'" />
                <img class="stroke" style="display:none"  src="Images/Employee-Stroke.png" />
            </li>
            <li  style="background-image:url('Images/X-AFH-Hospital-Clinic-Background.png')" id="clinic" >
                <div >Hospital / Clinic</div>
                <img src="Images/Doctor.png"  onmouseover="this.src='Images/Doctor-Stroke.png'" onmouseout="this.src='Images/Doctor.png'" />
               <div style="width:100px;height:350px;position:absolute;left:0;top:0;z-index:21"></div>
            </li>
            <li style="background-image:url('Images/X-AFH-University-School-Background.png')" id="school">
                 <div >University / School</div>
                <img src="Images/Student.png"  onmouseover="this.src='Images/Student-Stroke.png'" onmouseout="this.src='Images/Student.png'" />

            </li>
etc...

I am trying to implement a click event on the main <li> element in the list. However, the <img /> tags within the <li> are extending beyond its boundaries and triggering the click event unintentionally.

Is there a way to only apply the click event to the list item itself and not its child elements, even if they exceed the width and height of the main <li>?

Answer №1

To prevent child elements from triggering, you can utilize the stopPropagation() method.

For instance, consider the following scenario where all images within list elements are prevented from triggering an alert:

$("li").click(function(e) {
   alert("Clicking on the li will trigger this, not the img children");
});

$("li img").click(function(e) {
   e.stopPropagation(); // The img children inside li will not trigger the li event.
});

Here's a jsFiddle example for better understanding.

Answer №2

Instead of using the current answer, you have the option to directly compare the event.target with this (which refers to the element the click handler is attached to):

$('li').on('click', function(e) {
   if (e.target === this) {
     // this code will only run when the li element is clicked
   }
});
