[jQuery] Re: Why do i keep getting: test is not defined!
and i'm giving those 2!
Here is the full stuff again (posted in my last and first post as well)
Javascript:
function removeItem(name, obj)
{
var answer = confirm("Are you sure you want to delete: " + name + "?")
var test = obj;
if (answer)
{
$(test.parentNode.parentNode).fadeOut("slow");
}
}
HTML(not working):
click
HTML(working):
click
As you can see.. with both i give what it needs but yet the wrote:

How are you calling "removeItem" ?
It needs two parameters - the name and the object reference.

the code is simple and still not working.. the issue is that i try to
call a variable in a if that wasn't made there.. but how can i resolve
that?
Why is javascript not working how you would expect it to work :S i

first but that gave the same error as in the title.
Thanx.

what do you mean by: "not putting your event handler code inline"
And my javascript code is in a seperate .js file. but i have to call
it somewhere in the html and that's what you see in the href and
onclick. And i will take a look at that "unobtrusive javascript" but
any suggestions for good docs about that?

[jQuery] Re: Why do i keep getting: test is not defined!
Now why is this not working with a href?
I have just no clue.
My guess is that the context doesn't resolve correctly when you do
"javascript:" in the href, so when you do "this.parentNode", it probably
thinks "this" is the window object, which doesn't have a parent node. Thus
it returns undefined.
When you do "onclick" it knows the context is that "a" node so it works
properly.
Also, if you are getting into jQuery, I'd suggest learning a little bit
about "unobtrusive javascript", that is, not putting your event handler code
inline. This helps you keep your html markup and your JS code separated.

With this it works:

click
Now why is this not working with a href?

Your function is fine, however when you *call* the function removeItem,
you'll need to pass in two arguments -- otherwise obj will be undefined:
removeItem('myitem'); // obj is undefined
removeItem('myitem', myobject); // obj is defined
