[javascript] How to prevent a click on a '#' link from jumping to top of page?

I'm currently using <a> tags with jQuery to initiate things like click events, etc.

Example is <a href="#" class="someclass">Text</a>

But I hate how the '#' makes the page jump to the top of the page. What can I do instead?

I use something like this:

<a href="#null" class="someclass">Text</a>

If you want to migrate to an Anchor Section on the same page without page jumping up use:

Just use "#/" instead of "#" e.g

<a href="#/home">Home</a>
<a href="#/about">About</a>
<a href="#/contact">contact</a> page will not jump up on click..

Links with href="#" should almost always be replaced with a button element:

<button class="someclass">Text</button>

Using links with href="#" is also an accessibility concern as these links will be visible to screen readers, which will read out "Link - Text" but if the user clicks it won't go anywhere.

Just use <input type="button" /> instead of <a> and use CSS to style it to look like a link if you wish.

Buttons are made specifically for clicking, and they don't need any href attributes.

The best way is to use onload action to create the button and append it where you need via javascript, so with javascript disabled, they will not show at all and do not confuse the user.

When you use href="#" you get tons of different links pointing to the same location, which won't work when the agent does not support JavaScript.

Adding something after # sets the focus of page to the element with that ID. Simplest solution is to use #/ even if you are using jQuery. However if you are handling the event in jQuery, event.preventDefault() is the way to go.

You could just pass an anchor tag without an href property, and use jQuery to do the required action:

<a class="foo">bar</a>

The <a href="#!">Link</a> and <a href="#/">Link</a> does not work if one has to click on the same input more than once.. it only takes in 1 event click for each on multiple inputs.

still the best way to go is with <a href="#">Link</a>

then,

event.preventDefault();

$('a[href="#"]').click(function(e) {e.preventDefault(); });

So this is old but... just in case someone finds this in a search.

Just use "#/" instead of "#" and the page won't jump.

If the element doesn't have a meaningful href value, then it isn't really a link, so why not use some other element instead?

As suggested by Neothor, a span is just as appropriate and, if styled correctly, will be visibly obvious as an item that can be clicked on. You could even attach an hover event, to make the elemnt 'light up' as the user's mouse moves over it.

However, having said this, you may want to rethink the design of your site so that it functions without javascript, but is enhanced by javascript when it is available.

I have used:

<a href="javascript://nop/" class="someClass">Text</a>

You can also return false after processing your jquery.

Eg.

$(".clickableAnchor").live(
    "click",
    function(){
        //your code
        return false; //<- prevents redirect to href address
    }
);

Just use

<a href="javascript:;" class="someclass">Text</a>

JQUERY

$('.someclass').click(function(e) { alert("action here"); }

To prevent the page from jumping, you need to call e.stopPropagation(); after calling e.preventDefault();:

stopPropagation prevents the event from going up the DOM tree. More info here: https://api.jquery.com/event.stoppropagation/

There are 4 similar ways to prevent the page from jumping to the top without any JavaScript:

Option 1:

<a href="#0">Link</a>

Option 2:

<a href="#!">Link</a>

Option 3:

<a href="#/">Link</a>

Option 4 (Not recommended):

<a href="javascript:void(0);">Link</a>

But it's better to use event.preventDefault() if you are handing the click event in jQuery.

The #/ trick works, but adds a history event to the browser. So, clicking back doesn't work as the user may want/expect it to.

$('body').click('a[href="#"]', function(e) {e.preventDefault() }); is the way I went, as it works for already existing content, and any elements added to the DOM after load.

Specifically, I needed to do this in a bootstrap dropdown-menu inside of a .btn-group(Reference), so I did:

$('body').click('.dropdown-menu li a[href="#"]', function(e) {e.preventDefault() });

This way it was targeted, and didn't affect anything thing else on the page.

Solution #1: (plain)

<a href="#!" class="someclass">Text</a>

Solution #2: (needed javascript)

<a href="javascript:void(0);" class="someclass">Text</a>

Solution #3: (needed jQuery)

<a href="#" class="someclass">Text</a>
<script>
$('a.someclass').click(function(e) {
    e.preventDefault();
});
</script>

You can use #0 as href, since 0 isn't allowed as an id, the page won't jump.

<a href="#0" class="someclass">Text</a>

I've always used:

<a href="#?">Some text</a>

when trying to prevent the page jump. Not sure if this is the best, but it seems to have been working well for years.

You can use event.preventDefault() to avoid this. Read more here: http://api.jquery.com/event.preventDefault/.

you can even write it just like this:

<a href="javascript:void(0);"></a>

im not sure its a better way but it is a way :)

If you want to use a anchor you can use http://api.jquery.com/event.preventDefault/ like the other answers suggested.

You can also use any other element like a span and attach the click event to that.

$("span.clickable").click(function(){
alert('Yeah I was clicked');
});
