Your current code works, you can try it here: <a href="http://jsfiddle.net/s4UyH/" rel="noreferrer">http://jsfiddle.net/s4UyH/</a>

You have something outside the example triggering another <a href="http://api.jquery.com/click/" rel="noreferrer"><code>.click()</code></a>, check for other handlers that are also triggering a <code>click</code> event on that element.

I had the event firing two times initially, when the page get refreshed it fires four times. It was after many fruitless hours before I figured out with a google search.

I must also say that the code initially was working until I started using the JQueryUI accordion widget.

This can as well be triggered by having both <code>input</code> and <code>label</code> inside the element with click listener.

You click on the <code>label</code>, which triggers a click event and as well another click event on the <code>input</code> for the <code>label</code>. Both events bubble to your element.

See this pen of a fancy CSS-only toggle: <a href="https://codepen.io/stepanh/pen/WaYzzO" rel="noreferrer">https://codepen.io/stepanh/pen/WaYzzO</a>

Note: This is not jQuery specific, native listener is triggered 2x as well as shown in the pen.

This can be caused for following reasons:
<ol>
<li>You have included the script more than once in the same html file</li>
<li>You have added the event listener twice (eg: using <code>onclick</code> attribute on the element and also with jquery</li>
<li>The event is bubbled up to some parent element. (you may consider using <code>event.stopPropagation</code>).</li>
<li>If you use <code>template inheritance</code> like <code>extends</code> in <code>Django</code>, most probably you have included the script in more than one file which are combined together by <code>include</code> or <code>extend</code> template tags</li>
<li>If you are using <code>Django</code> template, you have wrongly placed a <code>block</code> inside another.</li>
</ol>
So, you should either find them out and remove the duplicate import. It is the best thing to do.
Another solution is to remove all <code>click</code> event listeners first in the script like:
<pre><code>$(&quot;#myId&quot;).off().on(&quot;click&quot;, function(event) {
event.stopPropagation();
});
</code></pre>
You can skip <code>event.stopPropagation();</code> if you are sure that the event is not bubbled.

I've found that binding an element.click in a function that happens more than once will queue it so next time you click it, it will trigger as many times as the binding function was executed. Newcomer mistake probably on my end but I hope it helps. TL,DR: Make sure you bind all clicks on a setup function that only happens once.

blocks|key|618585|text|就像Nick想说的那样，来自外部的东西触发了两次事件。要解决这个问题，您应该使用event.stopPropagation()来防止父元素冒泡。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|618586|$('button').click(function(event)+{

Just like what Nick is trying to say, something from outside is triggering the event twice. To solve that you should use event.stopPropagation() to prevent the parent element from bubbling.

<pre><code>$('button').click(function(event) {
 event.stopPropagation();
});
</code></pre>

I hope this helps.

One more possibility: 2 events are different in &quot;isTrusted&quot; value.
I just ran into this problem.
After doing a little debug, I found that the 2 events are different in &quot;isTrusted&quot; value.
<hr />
Conditions:
I called <code>element.click()</code> in anotherInputBox's &quot;keydown&quot; event handler.
After a keydown, <code>element</code> receive a pair of events, which one is &quot;isTrusted:true&quot;, another is &quot;isTrusted:false&quot;
According to MDN (<a href="https://developer.mozilla.org/en-US/docs/Web/API/Event/isTrusted" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Web/API/Event/isTrusted</a>), <code>isTrusted</code> is used to determine whether the event is user-triggered(true) or programatically-fired(false).
<hr />
Solutions:
a. Handle double fire better and block the second event by state in your use case
b. Choose whether you want user-triggered or programatically-fired
c. Do not use click(). Make the click handler a function, and both call the function from event handler directly

<pre><code>$('#button_id').click($.debounce(250, function(e) {
 e.preventDefault();
 var cur = $(this);
 if ($(cur).hasClass('btn-primary')) {
 //do something
 } else {
 // do something else 
 }
 }));
</code></pre>

Working on an old project.
I found out that when there is a radio input in the element and when the click will select the radio input, the jQuery click will be triggered twick and so it the Js

I have the following problem with this code:

<pre><code>&lt;button id="delete"&gt;Remove items&lt;/button&gt;

$("#delete").button({
 icons: {
 primary: 'ui-icon-trash'
 }
}).click(function() {
 alert("Clicked");
});
</code></pre>

If I click this button, the alert show up two times. It's not only with this specific button but with every single button I create.

What am I doing wrong?

jQuery Button.click() event is triggered twice
