Event: stopImmediatePropagation() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Note: This feature is available in Web Workers.
The stopImmediatePropagation() method of the
Event interface prevents other listeners of the same event from being called.
If several listeners are attached to the same element for the same event type, they are called in the order in which they were added. If stopImmediatePropagation() is invoked during one such call, no remaining listeners will be called, either on that element or any other element.
Syntax
stopImmediatePropagation()
Parameters
None.
Return value
None (undefined).
Examples
Comparing event-stopping functions
The example below has three buttons inside of three nested divs. Each button has three event listeners registered for click events, and each div has an event listener, also registered for click events.
- The top button allows normal event propagation.
- The middle button calls
stopPropagation()in its first event handler. - The bottom button calls
stopImmediatePropagation()in its first event handler.
HTML

CSS
div {
display: inline-block;
padding: 10px;
background-color: white;
border: 2px solid black;
margin: 10px;
}
button {
width: 100px;
color: #000088;
padding: 5px;
background-color: white;
border: 2px solid black;
border-radius: 30px;
margin: 5px;
}
JavaScript
const outElem = document.querySelector("pre");
/* Clear the output */
document.addEventListener(
"click",
() => {
outElem.textContent = "";
},
true,
);
/* Set event listeners for the buttons */
document.querySelectorAll("button").forEach((elem) => {
for (let i = 1; i <= 3; i++) {
elem.addEventListener("click", (evt) => {
/* Do any propagation stopping in first event handler */
if (i === 1 && elem.id) {
evt[elem.id]();
outElem.textContent += `Event handler for event 1 calling ${elem.id}()\n`;
}
outElem.textContent += `Click event ${i} processed on "${elem.textContent}" button\n`;
});
}
});
/* Set event listeners for the divs */
document
.querySelectorAll("div")
.forEach((elem) =>
elem.addEventListener(
"click",
(evt) =>
(outElem.textContent += `Click event processed on "${elem.firstChild.data.trim()}"\n`),
),
);
Result
Each click-event handler displays a status message when it is called. If you press the middle button, you will see that stopPropagation() allows all of the event handlers registered for clicks on that button to execute but prevents execution of the click-event handlers for the divs, which would normally follow. However, if you press the bottom button, stopImmediatePropagation() stops all propagation after the event that called it.
