jQuery - Uncaught SyntaxError: Unexpected token )

Question

I have - what I think - should be a very simple jquery script. When the register_hyperlink anchor is clicked, I am presented with the alert box, as expected; but after I click the OK, I am getting an error: Uncaught SyntaxError: Unexpected token )

The code block is below. I can't see anywhere that there are unbalanced parenthesis as the error states. The code below is inside the element of my html page.

<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.0.1.min.js"></script> <script type="text/javascript"> $(document).ready(function () { $("#register_hyperlink").click(function() { alert('Hello'); }); }); </script>

Does anyone have any idea how to go about debugging this? I've been at it for a while now, but am having zero luck.

Thanks!

The console error log will have some details about the source of the error and a stacktrace can you share them too? is there a onclick attribute in the a element — Arun P Johny

Only thing i can think of is trying .on('click', function(){ instead, you are using the most recent jquery lib , maybe .click is deprecated by now — Jay Rizzi

@JayRizzi No, .click() isn't deprecated...a simple check in the jQuery docs would confirm that. It's just a shortcut for .on("click". And being deprecated doesn't mean it's not available, it means it will be removed in a future build. — Ian

I had:

<a id="register_hyperlink" href="javascript:void();">Register an account</a>

I changed it to:

<a id="register_hyperlink" href="javascript:void(0);">Register an account</a>

So that explains it :-)

What have you got in the href attribute of your anchor? Alternatively do you have a an onClick attribute in the anchor or are you catching it anywhere else?

You are not preventing the default behaviour of the anchor and you may have a syntax error in the href. That would be my first guess.

You could change your posted function to:

$(document).ready(function () { $("#register_hyperlink").click(function(e) { e.preventDefault(); e.stopPropagation(); alert('Hello'); }); });

If you test with this function you may find, as Matt Ball points out that your problem was indeed elsewhere

you could use

<a id="register_hyperlink" href="javascript:;">Register an account</a>
