Hi i need to prevent the default action when the user clicked on a element and prevent its default action only for that time and need to do some other action. For which i used
document.body.onclick = function (e) {
e.preventDefault();
e.stopPropagation();
}
But now the problem is, after i performing the above action i need to remove the preventDefault
and stopPropagation
, because none of the link(a href) is getting triggered after this. So how to undo this after performing it? Please note that it is a pure JavaScript code and im not using any library like jquery. So i can't use .bind
and .unbind
. Any idea on this would be greatly appreciated.
You can replicate the behavior of bind
and unbind
using addEventListener
and removeEventListener
function stopIt(e) {
e.preventDefault();
e.stopPropagation();
}
document.body.addEventListener("click", stopIt);
// then later
document.body.removeEventListener("click", stopIt);
Note: IE <= 8 doesn't support addEventListener
and removeEventListener
, so you'll need to use attachEvent
as mentioned here - https://developer.mozilla.org/en-US/docs/Web/API/EventTarget.addEventListener#Compatibility
Don't bind the event to the body, bind the event to the element you need to prevent:
document.getElementById('theTarget').onclick = function(e) {
// ...
}
If I understand your requirement correctly, I'm afraid you cannot undo the e.preventDefault();
. But by default, the handler function will be executed before performing the default action. So in your case, you just don't need the e.preventDefault();
at all. And remember to attach the event listeners only to <a>
tags
var aTags = document.getElementsByTagName("a");
for (var i=0;i<aTags.length;i++){
aTags[i].onclick = function (e) {
// just perform your action here, don't need e.preventDefault();
}
}
Here is the working solution for breaking or rollback the stopImmediatePropagation():
Do unbind
$("#mydiv").unbind();
