[jQuery] Re: Breadcumb, error in for-loop

[Geir]

Thanks for helping out Althalos,

but BrCu really gives me what I want.
You see, for each parents('li') jQuery finds a:first, giving me the
array I want.

However, I wonder if the format of the array doesn't convert to insert
as html..

Success!!!

var BrCu = here.parents('li').find("a:first");
var BText = "";
for (i=3; i>=0; i--){
if (BrCu[i] != undefined){
BText = BText + ' > ' + '' + BrCu.eq
(i).html() + '';
}}
$('#breadcumb span.ins').html(BText);

Thank you for your help :)

Thanks!
Now we're getting somewhere.
(It's my first time writing a fo-expression)

You're right about the comparison.
It should be:   for (i=3; i>=0; i--)

> You're not initializing BText.
I think this is valid..
http://www.w3schools.com/JS/js_variables.asp

It's now writing to the page :))
However there are still a little to work with.

First: It writes "undefined" the first time ??
Second: It writes only the http-part, not tag and inner html

I can take hand of the last I think.. but the first??

You're not initializing BText.

Also, the comparison part of your "for" loop is wrong: should be "i ==
0", not "i=0".

Ok, saw one mistake, overwriting the text on each for.

So, tried this:
var BrCu = here.parents('li').find("a:first");
var BText;
for (i=3; i=0; i--){
if (BrCU[i] != undefined){
BText = BText + '> ' + BrCu[i];
}}
$('#breadcumb span.ins').html(BText);

But Firebug tells me BText is undefined.. No text written to my page..

I'm not an expert either, so I may be wrong. But I doubt that BrCU
really gives you what you want. find("a:first") will give you ONE
element by definition... it will not return an array of elements. I
think. Probably you need to do something like this:
var el = "";
var BrCu = here.parents('li');
BrCu.each(function () {
el = $(this).find("a:first");
bc += ">"+el;
});

This will probably not work straight off... but now bc will hold all
of the a elements...

Ok, understand the "undefined"-writing..
