Jshint: JSHint marks "javascript:void(0);" as a JS URL

[strugee]

If I assign an element's href to javascript:void(0); (as opposed to #), like so:

$('#foobar').attr("href", "javascript:void(0);");

JSHint picks up the javascript:void(0); construct as a Script URL:

PS C:\Users\hal9000\Development\strugee.github.com> grunt lint
Running "jshint:all" (jshint) task

   js\main.js
     30 |    $('#lightbulb-icon').attr("href", "javascript:void(0);");
                                                                    ^ Script URL.

when in fact it isn't doing anything and is semantically valid. There should be an exception for these types of Script URLs.

Nevermind.

Perhaps this should be a specialized warning? I can't be the only one to have been confused by this.

You're not.

Just put this line at the top of your file to disable the warning:

/*jshint scripturl:true*/

But the best way is to use "#" into the href and to return "false" for all javascript events:

<a href="#" onclick="doSomething();return false;">my link</a>

No, the best way is to keep your JavaScript out of your markup and attributes :P

@rwaldron: rectification, indeed

$('#foobar').attr("href", "#").click(function() {
  // do it
});

Passes jslint:
$('#foobar').attr('href','javascript'+String.fromCharCode(58)+'void(0);');

@MikeGodin looks like a separate bug.

@kcampion putting # and return false is not always desirebale
