Click on Div and More Specific Elements [duplicate] - javascript

This question already has an answer here:
Calling a function in jQuery with click()
(1 answer)
Closed 9 years ago.
I have a div that has a click() action that causes some animations on some other elements. That's all working well and good.
The problem is that there are some links within this div that have stopped working.
For example, here is a simplified example:
<div class="clickable-div">
<a href="#" onclick="javascript:my_function();">
</div>
$(document).ready(function() {
$('div.clickable-div').click(function() {
...
});
});
What can I do to run my_function when that link is clicked?
Another consideration is that there is plain text and images within clickable-div. I would like to still trigger .clickable-div when those items are clicked.
Edit:
Another strange thing. There is a mailto link within this div. When I click the mailto link, my browser does the mailto action (opens a compose window in my mail client), but it also does .clickable-div.click. I would prefer that it doesn't do both.

Have a look here: http://jsfiddle.net/J2jMV/
CODE
$('div.clickable-div').click(function() {
alert("I'm not your function");
});
$('div.inner').click(function(e) {
e.stopPropagation();
alert("I'm INNER!");
});
$("#clickme").click(function(e){
e.stopPropagation();
alert("Hello my function");
});
have also a look here for event bubbling: http://javascript.info/tutorial/bubbling-and-capturing
hope it helps

Maybe I'm misreading the question, but it looks like you simply need to point to a different selector, also remove the onclick="", and simply put that function within the jQuery click event handler.
Also, you want to separate JS from HTML (it's a best practice). Having onclick events also creates inline scripts in older browsers like IE8-- and can slow performance.
<div class="clickable-div">
<a href="#">
</div>
$('div.clickable-div a').on('click', function () {
// do the things you already had here, only if there is no mailto
if ($(this).attr('href').indexOf('mailto') <= -1) {
e.preventDefault(); // this will prevent the mailto
// now run your my_function animations
my_function();
}
});

jQuery parent element event 'click' blocks a href links [duplicate]

This question already has answers here:
jquery .click overriding anchor href when i dont want it to!
(4 answers)
Closed 8 years ago.
When setting up a div with a class, attaching a click event to that class using jQuery, it prevents any child href from working.
For example:
HTML
<div class="someClass">
some text here
and a link
</div>
JS
$('body').on('click', '.someClass', function(e) {
alert("clicked");
});
jsfiddle for this: http://jsfiddle.net/w6ero5j5/2/
it will always alert the message, even when clicking on the link.
how can I make the link works?
I dont know why do you want this. But, it happen when you put alert function.
Then If you execute this, there is not problem. code here
$('.someClass').on('click', function(){
var $this = $(this);
if ( $this.hasClass("ok") ) {
$this.removeClass("ok");
} else {
$this.addClass("ok");
}
});

How can I stop <a> tag jumping to the target which is specified by href attribute? [duplicate]

This question already has answers here:
jQuery disable a link
(18 answers)
Closed 8 years ago.
I know that Link will just do the job,
but what I intend to do is to specify a href, but will not jump to it when being clicked, just like:
Link
When I click on this link, I'd just like the onclick is invoked, whereas href is just a 'show' without jumping to http://mydomain.com.
How could this be done by javascript or css? Thanks a lot!
There are a few ways you can do this. If you must fulfill the answer within the HTML then:
click here
But better practice is to follow Andrew Spartar's solution and separate the JavaScript using a class or other selector.
add class to the link, for example: class="not-jump"
then in jQuery add listener:
$( ".not-jump" ).click(function(e) {
e.preventDefault();
});
That should do the trick.
like this:
Link
JS:
function myFunc(e) {
e.preventDefault();
...
}
and to separate html from js:
Link
JS:
$(".somelink").on('click', function(event) {
event.preventDefault();
});

JavaScript Event Handler jQuery

I am working on a hand me down project that was written by someone who was clearly better at HTML and JavaScript than myself. The html has AJAX links like this:
<ul class="subNav">
<li><a link="contacts.html">Contacts</a></li>
<li><a link="contacts_add.html">Add Contact</a></li>
</ul>
Which I think are handled in this code:
$('.subNav li a').click(function() {
var href = $(this).attr('link')
$('#mainStage').load(href, function() {
pageLoad();
})
})
All of the code above works perfectly.
My problem is I can't seem to recreate this functionality. I am using this HTML:
<div class="nameTitle colorOne"><a link="contacts_add.html">
<span class="firstNameField">Contact Name</span>
</a></div>
and this JavaScript:
$('.nameTitle').click(function() {
alert('')
$('#mainStage').load("contacts_add.html", function() {
pageLoad();
})
})
When I click the "nameTitle" class it should load contacts_add.html into the mainStage section of the page but I cannot see anything happen. I am sure someone fluent with this style of coding could tell me why my event never fires but the earlier code does.
Thanks in advance,
You should try altering your code to something like this:
$('.nameTitle').click(function() {
//This line finds the address to load
var address = $(this).children("a").attr("link");
//This line loads the address and then runs the pageLoad function when it has completed
$('#mainStage').load(address, function() {
pageLoad();
});
});
If this doesnt work it may be because the html is loaded dynamically. In this case you need to use .on, see this link here.
In response to Brett's comment below ive put together a jsfiddle showing .on in action here. Also i added .preventDefault as this could cause a problem.
try with
$('.nameTitle a').click(function() {
It can be that you're trying with a browser which accepts click only on 'a' tags, albeit they're getting rare hopefully.
The 'click' event will never be raised on your div, since there is an inner a element with an href defined. Once you click, the event will be raised on the anchor link first which will, by default, redirect to the location specified by the href. In order to get this working, catch the click when it is raised at the a:
$('.nameTitle a').click(function(e) {
e.preventDefault(); // prevent browser from following href
alert('');
$('#mainStage').load("contacts_add.html", function() {
pageLoad();
});
});
Demo -- Commented out the load, since that page isn't on this server. Also notice I changed your a element to have attribute href instead of link.

Good way to keep an anchor tag without default url

In our page we have a slew of anchor tags to which we dynamically attach click handlers. In such a case what is the best way to keep an anchor tag in the mark up?
Currently we have
<a href="javascript:void(0);" >....</a>
We need void value for href as some of them may not get attached with click handlers.
Ommit the href-attribute and when assigning the onclick also set the cursor-style of the elements to "pointer" , otherwise users with JS disabled will be confused when clicking on the elements and nothing happens.
Returning false from a jQuery event handler will prevent the default behavior (and bubbling) for you. There's no need to mess with the href attribute (though that won't hurt).
$(document).on("click", "a.yourSelector", function(){
//your code
return false;
});
Or of course jQuery pre 1.7
$(document).delegate("a.yourSelector", "click", function(){
//your code
return false;
});
For more information on cancelling dom events, see this question (and answer) and this link
The simpler code would be like this:
<a href='#' class='do-stuff'>Link</a>
The "#" sign keeps the html code clean, and readable
jQuery(document).ready(function() {
jQuery(".do-stuff").click(function() {
alert("clicked");
return false; // disables default link action
});
});

jQuery DIV click, with anchors

To make click-able divs, I do:
<div class="clickable" url="http://google.com">
blah blah
</div>
and then
$("div.clickable").click(
function()
{
window.location = $(this).attr("url");
});
I don't know if this is the best way, but it works perfectly with me, except for one issue:
If the div contains a click-able element, such as
<a href="...">, and the user clicks on the hyperlink, both the hyperlink and div's-clickable are called
This is especially a problem when the anchor tag is referring to a javascript AJAX function, which executes the AJAX function AND follows the link in the 'url' attribute of the div.
Anyway around this?
If you return "false" from your function it'll stop the event bubbling, so only your first event handler will get triggered (ie. your anchor will not see the click).
$("div.clickable").click(
function()
{
window.location = $(this).attr("url");
return false;
});
See event.preventDefault() vs. return false for details on return false vs. preventDefault.
$("div.clickable").click(
function(event)
{
window.location = $(this).attr("url");
event.preventDefault();
});
Using a custom url attribute makes the HTML invalid. Although that may not be a huge problem, the given examples are neither accessible. Not for keyboard navigation and not in cases when JavaScript is turned off (or blocked by some other script). Even Google will not find the page located at the specified url, not via this route at least.
It's quite easy to make this accessible though. Just make sure there's a regular link inside the div that points to the url. Using JavaScript/jQuery you add an onclick to the div that redirects to the location specified by the link's href attribute. Now, when JavaScript doesn't work, the link still does and it can even catch the focus when using the keyboard to navigate (and you don't need custom attributes, so your HTML can be valid).
I wrote a jQuery plugin some time ago that does this. It also adds classNames to the div (or any other element you want to make clickable) and the link so you can alter their looks with CSS when the div is indeed clickable. It even adds classNames that you can use to specify hover and focus styles.
All you need to do is specify the element(s) you want to make clickable and call their clickable() method: in your case that would be $("div.clickable).clickable();
For downloading + documentation see the plugin's page: jQuery: clickable — jLix
I know that if you were to change that to an href you'd do:
$("a#link1").click(function(event) {
event.preventDefault();
$('div.link1').show();
//whatever else you want to do
});
so if you want to keep it with the div, I'd try
$("div.clickable").click(function(event) {
event.preventDefault();
window.location = $(this).attr("url");
});
<div class="info">
<h2>Takvim</h2>
Click Me !
</div>
$(document).delegate("div.info", "click", function() {
window.location = $(this).find("a").attr("href");
});
