AnyLink and javascript functions instead of links

[sweikert]

Hi guys,

I found your AnyLink scripts the other day, and love'em - but I'm looking to use them in a slightly different manner than 'normal'.

In the drop-down menu, one item is a 'delete' function - and in the past, I've had this link tied to a JS function that has a confirm() in it - i.e. a 'You sure you want to delete this?' style bit.

Now putting in "javascript:myDelFunction(x)" in the menu link array, instead of a normal URL, works fine up to a point. Hover over the menu, slide down to the item in question, click it - the confirm message comes up. And in IE 6, it works fine all the way through. But in Firefox (1.0.7 at least), after clicking the 'OK' confirm button, I get a JS error - 'b has no properties'. This seems to be in the function ' contains_ns6'. While trying to figure a workaround, I plopped in 'alert(b)' at the top of that function; when scrolling through the menu items, I'll get alerts with the contents of the link in question - but when clicking on my trouble menu item, the confirm comes up - I move the mouse off the menu to click 'OK' - and since I'm moving the mouse off the menu, the contains_ns6 function gets triggered again, and the alert comes up 'null'.

Any thoughts on a workaround for this issue?

Thanks much!

Still looking for some help with this.

There is a way to avoid this error but, doesn't the script work fine in FF even with the error? Try this:

Get rid of the alert(b) thing and close the javascript console.

If you do this, does the script work OK?

The trick is how you deal with the confirm popup. If you just hit the return key to say "OK", it's fine - because you're not moving your mouse away from the spot it was when you clicked on the drop-down menu item.

But if you move the mouse away from where it was, and over the confirm popup - that's when things go blooey. It's at that point that the contains_ns6 function gets called again, and since the mouse isn't over any of the drop-down menu items, b is null, and the script fails.

I'm going to look into trying to store the 'b' var contents elsewhere, in a temp var when the script gets called and there's something in it - and then when the script is called and b is null, to reference the temp var's value in its place...

So near the top of the script, I added:

var tempB = '';

and inside the contains_ns6 function, right off the bat:

if (b == null) b = tempB;
if (b != null) tempB = b;

and it seems to have done the trick. Works like a charm in IE6 and FF1.0.7.
