*content_window*
BLOG CATEGORY: Javascript | Permalink | Posted on: September 19th, 2011 |
Another stump today - a simple javascript function - or is it?
Well technically it was a very simple function - something like:
function set_content_window(url){
document.getElementById('iframe_o_mine').src = url;
}
Simple enough right? Well not so. I got no errors just nothing at all - the worst kind of error is one that does not tell you it is there.
So I though the function name looked a bit system-like, so I changed it to:
function update_content_window(url){
document.getElementById('iframe_o_mine').src = url;
}
Same thing - turns out the reserved name must be a wildcard match because just having the instance of "content_window" has no effect when defining a function with such a name. Odd! Updated once more to something silly like the one below and it worked as expected.
function any_other_function_name(url){
document.getElementById('iframe_o_mine').src = url;
}
scrollup(),scrolldown() is not a function

Although I have not found the answer, I thought I should at least document it as a possible bug.
I had a project that involved doing a scrolling area
I wrote a couple of simple functions to handle the jQuery and named them scrollup() and scrolldown(). I uploaded my changes and received the ERROR: scrollup() is not a function. I checked my spelling on the function and the call and everything looked fine. Exhausted all other traditional avenues for debugging and found nothing .... time went by ......
..... yep .......................
............. a lot of time went by ...... and then I decided I would try something different in desperation .... I renamed the functions scroll_up() and scroll_down() and ...... they work fine. WTF
Weird stuff. I imagine they are reserved by the browser (in this case all browsers had same issue) or something but can't find a whole lot of information on it. No traces of them being reserved here
