Can you put 2 JavaScript onClick events in a single element, this is what I have tried so far, I've tried calling functions but that wouldnt work either.
<div class="contactme">Message me!</div>
Calling functions:
function hide(){
document.getElementById('download').style.display='none';
document.getElementById('skype').style.display='none';
}
HTML:
<div class="contactme">Message me!</div>
However none of them seem to work.
Of course, you can do it in pure Javascript. Your HTML doesn't need the onclick property at all.
HTML:
<div class="contactme">Message me!</div>
JavaScript:
var contact = document.getElementsByClassName("contactme")[0];
contact.addEventListener("click", function() {
document.getElementById('download').style.display='none';
document.getElementByID('skype').style.display='none';
}
Now you can use contact.addEventListener to add any function you want, like this:
contact.addEventListener("click", hide);
try this
http://jsfiddle.net/ErnestoOsuna/2pjfL5oq/
Message me!
element=document.getElementById('some_id');
element.addEventListener('click',some_func);
element.addEventListener('click',some_func2);
Your both code is correct but, in first code you typed 'document.getElementByID'.
just fixed it.
Use element.addEventListener(Event, Function, false);
document.getElementById('ELEMENTID').addEventListener('click', function(e) {
// onclick code here
}, false);
document.getElementById('ELEMENTID').addEventListener('click', function(e) {
// more code here
}, false);
How to call multiple JavaScript functions in onclick event?
And about your snippet,
onclick="hide()"
You can do it logically i.e:
<div class="contactme">
Message me!'
</div>
Now in javascript do this programatically:
function myfun(var execute){
if(execute=="one"){
// execute this if it is one
}
else(execute=="two"){
// execute this if it is two
}
}
Now here whenever you call myfun('one') it execute your first condition and myfun('two') it execute second.

So I am writing a code that displays an alert box whenever the mouse hovers over a piece of text in HTML. The problem that I have is it is not working and I am not sure why. I tried finding help online but none of them worked. I need something that doesn't use JQuery for this assignment. What I have tried is to use function when activated with the mouse over event handler but that also didn't work.
This is my code:
function mouseOver(){
showAlert();
}
function showAlert(){
alert("Alert!");
}
This is another method that I have tried:
function mouseOver(){
document.getElementById("text").alert("Alert!");
}
Try this
function mouseOver(){
alert("Alert!");
}
You can use this
document.getElementById("text").addEventListener("mouseover", function( event ) {
alert("Alert!");
}, false);
<p id="text">Hover Me</p>
I have a link:
<ul id="titleee" class="gallery">
<li>
Talent
</li>
</ul>
and I am trying to trigger it by using:
$(document).ready(function() {
$('#titleee').find('a').trigger('click');
});
But it doesn't work.
I've also tried: $('#titleee a').trigger('click');
Edit:
I actually need to trigger whatever get's called here <a href="#inline" rel="prettyPhoto">
If you are trying to trigger an event on the anchor, then the code you have will work I recreated your example in jsfiddle with an added eventHandler so you can see that it works:
$(document).on("click", "a", function(){
$(this).text("It works!");
});
$(document).ready(function(){
$("a").trigger("click");
});
Are you trying to cause the user to navigate to a certain point on the webpage by clicking the anchor, or are you trying to trigger events bound to it? Maybe you haven't actually bound the click event successfully to the event?
Also this:
$('#titleee').find('a').trigger('click');
is the equivalent of this:
$('#titleee a').trigger('click');
No need to call find. :)
Sorry, but the event handler is really not needed. What you do need is another element within the tag to click on.
<a id="test1" href="javascript:alert('test1')">TEST1</a>
<a id="test2" href="javascript:alert('test2')"><span>TEST2</span></a>
Jquery:
$('#test1').trigger('click'); // Nothing
$('#test2').find('span').trigger('click'); // Works
$('#test2 span').trigger('click'); // Also Works
This is all about what you are clicking and it is not the tag but the thing within it. Unfortunately, bare text does not seem to be recognised by JQuery, but it is by vanilla javascript:
document.getElementById('test1').click(); // Works!
Or by accessing the jQuery object as an array
$('#test1')[0].click(); // Works too!!!
Since this question is ranked #1 in Google for "triggering a click on an <a> element" and no answer actually mentions how you do that, this is how you do it:
$('#titleee a')[0].click();
Explanation: you trigger a click on the underlying html-element, not the jQuery-object.
You're welcome googlers :)
If you are trying to trigger an event on the anchor, then the code you have will work.
$(document).ready(function() {
$('a#titleee').trigger('click');
});
OR
$(document).ready(function() {
$('#titleee li a[href="#inline"]').click();
});
OR
$(document).ready(function() {
$('ul#titleee li a[href="#inline"]').click();
});
With the code you provided, you cannot expect anything to happen. I second #mashappslabs : first add an event handler :
$("selector").click(function() {
console.log("element was clicked"); // or alert("click");
});
then trigger your event :
$("selector").click(); //or
$("selector").trigger("click");
and you should see the message in your console.
Well you have to setup the click event first then you can trigger it and see what happens:
//good habits first let's cache our selector
var $myLink = $('#titleee').find('a');
$myLink.click(function (evt) {
evt.preventDefault();
alert($(this).attr('href'));
});
// now the manual trigger
$myLink.trigger('click');
This is the demo how to trigger event
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("input").select(function(){
$("input").after(" Text marked!");
});
$("button").click(function(){
$("input").trigger("select");
});
});
</script>
</head>
<body>
<input type="text" value="Hello World"><br><br>
<button>Trigger the select event for the input field</button>
</body>
</html>
This doesn't exactly answer your question, but will get you the same result with less headache.
I always have my click events call methods that contain all the logic I would like to execute. So that I can just call the method directly if I want to perform the action without an actual click.
For links this should work:
eval($(selector).attr('href'));
You should call the element's native .click() method or use the createEvent API.

We can do it in many ways...
CASE - 1
We can use trigger like this : $("#myID").trigger("click");
CASE - 2
We can use click() function like this : $("#myID").click();
CASE - 3
If we want to write function on programmatically click then..
$("#myID").click(function() {
console.log("Clicked");
// Do here whatever you want
});
CASE - 4
// Triggering a native browser event using the simulate plugin
$("#myID").simulate( "click" );
Also you can refer this : https://learn.jquery.com/events/triggering-event-handlers/
Shortest answer:
$('#titlee a').click();
I'm using this in my HTML:
Click
It calls the function preload() on an external js-file and works fine so far.
But i have dozens of those links and would like to remove alle those "return false" and put only one directly inside the preload()-function in the js-file.
But it will always be ignored?! Does the "return false" really only work inside the onclick="..."?
function preload () {
// some code
return false;
}
Click
or use addEventListener
For example:
Click
<script type="text/javascript">
document.querySelector('.link').addEventListener('click', function (e) {
// some code;
e.preventDefault();
}, false);
</script>
Putting return false; in the inline onclick attribute prevents the default behavior (navigation) from occurring. You can also achieve this by clobbering the onclick attribute in JavaScript (i.e. assigning the .onclick property to be a function that returns false), but that's frowned upon as old-fashioned and potentially harmful (it would overwrite any additional event listeners attached to that event, for example).
The modern way to prevent the <a> element's default click behavior from occurring is simply to call the .preventDefault() method of the triggering event from within the attached event listener. You can attach the listener the standard way, using .addEventListener()
Some examples:
// this works but is not recommended:
document.querySelector(".clobbered").onclick = function() {
return false;
};
// this doesn't work:
document.querySelector(".attached").addEventListener("click", function() {
return false;
});
// this is the preferred approach:
document.querySelector(".attachedPreventDefault").addEventListener("click", function(e) {
e.preventDefault();
});
If you click me, I don't navigate<br/>
<a class="clobbered" href="/fake">If you click me, I don't navigate</a>
<br/>
<a class="attached" href="/fake">If you click me, I navigate</a>
<br/>
<a class="attachedPreventDefault" href="/fake">If you click me, I don't navigate</a>
I think if you put it into the preload function and in the onclick event just put return false will work. Maybe you've tried this code?
Click
Try to put the return false clause into the inline function:
<input onclick="yourFunction();return false;">
I would maybe suggest not using onClick() and instead using similar jQuery.
I am having a lot of trouble with jQuery. I have to click twice on a button to make the page disappear. I have tried importing both versions of jQuery and I tried to use the fadeOut() function on different elements, but nothing has prevailed. It works the second time I click, but never the first. This is a recurring problem, and I need to know how it can be fixed. Here is my code:
HTML:
<body>
<h1>CSS3 Buttons Showcase</h1>
Click Me!
</body>
JavaScript:
function fadeBg(){
$("#btn-1").click(function(){
$("body").fadeOut(1000);
})
}
You must change your function to:
function fadeBg(){
$("body").fadeOut(1000);
}
In your HTML code onclick is being set to run your function fadeBg. So in your function you must put what you want to run; in this case $("body").fadeOut(1000);
The issue is that you're not binding the jQuery event handler until the fadeBg() function is called on the first click. Try this instead:
<h1>CSS3 Buttons Showcase</h1>
Click Me!
$(function() {
$("#btn-1").click(function(){
$("body").fadeOut(1000);
})
});
There are two ways to bind a click to an element :
1. The old dirty inline javascript (avoid)
(HTML) : <button onclick="doSomething()">
and 2. the cleaner event binding
(HTML) : <button id="myButton">
(JS) : $('#myButton').click( doSometing )
You mixed both, binding two clicks on the same element.
<button onclick="doSomething()">
function doSomething(){ // will be done on first click
$('#myButton').click( doSometingElse ) // will be done on second click
}
You are doing the same action twice, the code is:
HTML
<body>
<h1>CSS3 Buttons Showcase</h1>
Click Me!
</body>
JavaScript
$(document).ready(function() {
$("#btn-1").click(function(){
$("body").fadeOut(1000);
})
}
function fadeBg(){
$("#btn-1").click(function(){
$("body").fadeOut(1000);
})
}
You added the onclick event directly in your html. This function adds a second event to the same button.
Just remove the onclick event in your element And do this:
$("#btn-1").click(function(){
$("body").fadeOut(1000);
})
It's considered bad practice adding onclick events directly in your html element. You can but it doesn't look good.
my question is a short one but I couldn't figure it out by myself. I've got a function like -> http://jsfiddle.net/gtU56/ . I'm calling a javascript-function with an event-listener(onclick) in my html-code. The function itself is more complex but I need the last snippet. By clicking 'Show More' the text should change. Why won't the text change?
Because the toggleText function isn't available when the html code is rendered.
In other words the function isn't set until the page is ready so the onclick function doesn't reference anything.
Either have the function like here http://jsfiddle.net/gtU56/2/
or have it in the head of the page because its needs to be ready immediately
If you want it to wait for the ready state you can do the following and remove the onclick action all together
http://jsfiddle.net/gtU56/7/
$(".text").click(function()
{
$(".text").toggle();
});
toggleText = function () {
$('.text').toggle();
}
check here http://jsfiddle.net/gtU56/3/
It's because of how you're loading the function. Switch it from onLoad to no wrap (head) and it works fine.
jsFiddle example
Using jsFiddle's onLoad wraps your function in a window.onload call like this:
<script type="text/javascript">
//<![CDATA[
$(window).load(function(){
function toggleText() {
$('.text').toggle();
}
});//]]>
</script>
While no wrap (head) just adds it normally like this:
<script type="text/javascript">
//<![CDATA[
function toggleText() {
$('.text').toggle();
}
//]]>
</script>
since you are already claiming having jquery, you need not use inline javascript. try this
var elems = $('.text');
elems.click(function(){
elems.toggle();
});
fiddle : http://jsfiddle.net/gtU56/5/
$('.text').click(function() {
$('.text').toggle('slow', function() {
// do your animation..
});
});
Js Fiddle
This is the solution - http://jsfiddle.net/gtU56/6/
You need to first make sure that the function is registered after page load. Then, bind a click event to the div.
Hope this helps!
First you should organize you jQuery code like this:
$.(document).ready(function() {
// enter jQuery code here
});
Otherwise you're accessing a not completly loaded html document.
Also, you don't need the event-listener if you are using jQuery.
This should work for you:
$.(document).ready(function() {
$('.text').click(function() {
$(this).toggle();
});
});
Is very easy. You can use ID or CLASS.
onclick="$('NAME ID or CLASS').toggle(ANIMATION or DURATION);"
<div>
<div class="text" onclick="$('.text2').toggle(400);">Show More</div>
<div class="text2" style="display:none">Show Less</div>
</div>
