Middle Click (new Tabs) And Javascript Links

I am in charge of a website at work and recently I have added ajaxy requests to make it faster and more responsive. But it has raised an issue. On my pages, there is an index table

Solution 1:

Yes. Instead of:

<ahref="javascript:code">...</a>

Do this:

<a href="/non/ajax/display/page"id="thisLink">...</a>

And then in your JS, hook the link via it's ID to do the AJAX call. Remember that you need to stop the click event from bubbling up. Most frameworks have an event killer built in that you can call (just look at its Event class).

Here's the event handling and event-killer in jquery:

$("#thisLink").click(function(ev, ob) {
    alert("thisLink was clicked");
    ev.stopPropagation();
});

Of course you can be a lot more clever, while juggling things like this but I think it's important to stress that this method is so much cleaner than using onclick attributes.

Keep your JS in the JS!

Solution 2:

Yes, You need to lookup progressive enhancement and unobtrusive Javascript, and code your site to work with out Javascript enabled first and then add the Javascripts functions after you have the basic site working.

Solution 3:

I liked Oli's approach, but it didn't discern from left and middle clicks. checking the "which" field on the eventArgs will let you know.

$(".detailLink").click(function (ev, ob) {
    //ev.which == 1 == left//ev.which == 2 == middleif (ev.which == 1) {
        //do ajaxy stuffreturnfalse; //tells browser to stop processing the event
    }
    //else just let it go on its merry way and open the new tab.
});

Solution 4:

It would require some testing, but I believe that most browsers do not execute the click handler when you click them, meaning that only the link is utilized.

Not however that your handler function needs to return false to ensure these links aren't used when normally clicking.

EDIT: Felt this could use an example:

<ahref="/Whatever/Wherever.htm"onclick="handler(); return false;" />

Solution 5:

<a href="/original/url" onclick="return !doSomething();">link text</a>
