I wanna get some deep information about how browser implements the dispatch mechanism of events , native setTimeout and setInterval. Any books or articles reference it?

I'm trying to build the framework for an AJAX back/forward button fixer. Basically it uses the hash fix for them (using text after the # to add history objects). To this effect, the function to check for updates has to be run every second or so. No problem, I'll just use setInterval for that.
For whatever reason, though, setInterval gives me an error. Specifically that oldLocation (global variable) is undefined (in the checkURL function). So I try setTimeout. Same thing. When I just call the function explicitly once (adding checkURL(); to the end of the script) everything works wonderfuly; it's just setting it up on a timer that messes up. Frankly, I've no idea why it's doing this. (The bug just seems so odd) Maybe a more advanced JS coder can shed some light on it.. Code:
I have a script that I have tried running using both setTimeout and setInterval. It works fine in every browser except safari 3. It will run fine for a few loops and then stop.
View 2 Replies View RelatedI've been trying a number of different approaches but can't seem to get it right. The idea was to loop the main funtion of the script (loadContent) by ending with the setTimeout, that I had to move to another function. Why, I don't know, but that's the only way it works. I'm a professional PHP programmer, getting to grips with Javascript in this era where Ajax rules firmly is part of my job. Can't say I have been enjoying the experience so far, though.Right, enough bashing for today! The idea was to have a simple script, linked to a php script that would load images, based on the data sent via Javascript and an XML datafile. This does happen, only: the timeout of 5 or 6 seconds doesn't seem to last even a millisecond.

I am creating table with input fields. I dynamically add new rows to the table with the following code:
Now I would like also to add autocompleter on newly created input. I do not know how to select newly created input with jQuery. I know how to do that with javascript:
So I would like to be able to do the same with jQuery so I can add autocompleter on newly added input field articles[].
I add autocompleter to all fields at the begging with the following code:

I recently launched a question answer site that connects people with
problems to those with solutions. We let people with problems pay
solution providers $0.25 for problems in over 100 categories.
As part of our service we let people review past problems and also
provide resources for their own research.
Can anyone tell me (in their opinion)?

View 2 Replies View RelatedI have a forum with over 5000 topics (lots of content in each topic) and I have a wiki-website with over 4000 articles. Both share the same database and are similar in context.
Now, I was wondering if there is a JavaScript out there that can could scan my forum page and underline words on that page that are articles on the wiki. For instance, if I have an article in the wiki entitled "Heart", where ever "Heart" appears in the forum, it is underlined and linked to that exact article on the wiki.
This conceptual idea is very similar to In-Text advertisements, such as Kontera, but I can't seem to find the scripting they use.

View 2 Replies View RelatedI have a background that is a shelf full of books, I wanted to figure out what I would need to do in order to make a random number of books pop out on mouse over (individually), and upon click have the book pulled out and be flipped through and read like a book. Would I have to recreate the library picture completely to make the random books moveable? And would I have to create the books that I want to move from the bookshelf?
how to pull the book out from the book shelf so that it looks like it's coming towards me and then to make it look like it has been pulled out. Would I need to use animation for this? What would be the parts to the animation required?
A little background on my knowledge of javascript: I understand the concepts of it and can understand it when I read it or its explained to me. I am looking to create something as simple as I can, I thought having a background and something basic like a few books be able to pop out. When I realized css couldn't do this and css3 wasn't supported by most browsers I turned to javascript and have been trying to figure out the steps I would need to do to do this specifically.
I have the following function that's supposed to say "Please make a guess" 20 seconds after an initial confirmation is displayed. However, it's immediately displayed as soon as someone hits "Cancel". If I change it's time to 40000 (20 seconds after the initial function is called), it does do it 40 seconds total, so it kind of does what I want. So it seems that the second setTimeout is initiated from the time the script is called generally, but I'm looking for a way specifically to have the 20 seconds start only after the "cancel" button is hit.

View 1 Replies View RelatedI like having scripts external, but I wonder about the security of internal anyway. Someone could save and change the HTML, right? But is that possible with an external script? I always thought not (unless there was an error), until a person on this forum was able to grab the script I was working with at the time. No problem with that, but it brings up the question in my mind about security in general surrounding java-script.

View 3 Replies View RelatedDoes anyone have a reputable reference about internal string storage in
JavaScript? (for some particular implementation I mean).
Say having 1,048,576 characters long string from the geometric
progression:
function generateLargeString() {
var s = 'a'
for (var i=1; i<21; ++i) {
s = s.concat(s);
}
return s;
}
- the internal size should be 2 mebibytes and not 1 (?) if strings are
indeed stored as Unicode 16-bit. From the other hand it would be
tempting for an engine developer do not spend extra bytes on ASCII
chars...
So does anyone know of any documented engine optimizations on the
matter? Would be expected on some engine to have the string from above
twice smaller than say
function generateLargeString() {
// 1200 ETHIOPIC SYLLABLE HA
var s = String.fromCharCode(0x1200);
for (var i=1; i<21; ++i) {
s = s.concat(s);
}
return s;
}
