How to event click on DIV except if the clicked element is a specific one-CodePudding

I have a div with several elements. I want to make an event to handle clicking on any element of this div, EXCEPT a specific one.

<div id="mydiv">
<img id="myimage" src="myimage.gif"/>
<img id="myimage2" src="myimage2.gif"/>
<img id="myimage3" src="myimage3.gif"/>
</div>

<script>
document.getElementById('mydiv').addEventListener('click', function() {
// if element is not the one with id=myimage3 do something
alert('You clicked on image1 or image2');
});
</script>

CodePudding user response：

Use the event parameter to the callback and check that its targets id attribute is not myimage3:

document.getElementById('mydiv').addEventListener('click', function(e) {
  if (e.target.id != 'myimage3')
    alert('You clicked on image1 or image2');
});

<div id="mydiv">
  <img id="myimage" src="https://via.placeholder.com/100?text=image1" />
  <img id="myimage2" src="https://via.placeholder.com/100?text=image2" />
  <img id="myimage3" src="https://via.placeholder.com/100?text=image3" />
</div>

Elements in HTML can be identified is a few different ways: by class and by id. Classes are collections of elements that can be selected, styled, and further manipulated whereas ids are unique are should be specific to a single element. Since you want to exclude a specific element from being selected, you'll need to compare the selected element's id with that of the one you wish to exclude.

This can be done with a callback like in @Nick 's answer using the event.target property.

Essentially what e.target does is it gets the element which triggered the event and all of its various attributes eg. tagName and style.

Pass 'event' as an argument to the callback function.

Wrap the alert in an if statement checking if the

event.target.id !== 'myimage3'
