[jQuery] Re: closure inside ajax method
The order of elements in a simple array like this is guaranteed.
Looping over an object with a for in loop, the order is not
guaranteed, though by convention most browsers honor the order in
which the elements were added. jQuery would have to go out of its way
to return the elements from your array in a different order. So, yes,
you can count on the order being correct.
To answer your original question, the "jQuery way" to do this would be
to use $.each(). If you wanted to achieve the closure in pure
JavaScript, you could do the following:
var i, len, myArray = ['one', 'two'], innerFunc;
innerFunc = function (i) {
$.ajax({
url : 'http://localhost/',
complete : function () {
alert(i);
}
});
}
for (i = 0, len = myArray.length; i < len; ++i) {
innerFunc(i);
}

[jQuery] Re: $.ajax beforeSend Accept-Encoding behavior
OK, I now see the console message where jQuery refuses to set the
unsafe header, so it looks like this behavior is expected. I am having
trouble finding a good explanation of what is unsafe about it though.
Is it that this header is unsafe when used in combination with some
other header value (say, a particular MIME type or charset)? In other
words, is there no way to change this?

[jQuery] $.ajax beforeSend Accept-Encoding behavior
I'm trying to make an Ajax request, specifically requesting a non-
gzipped response. Here's how I am going about it:
$.ajax({
url : 'http://my.valid.url/',
method : 'get',
beforeSend : function (xhr) {
xhr.setRequestHeader('Accept-Encoding', 'identity');
xhr.setRequestHeader('X-Test', 'foo');
}
});
Watching the action with LiveHTTPHeaders in Firefox 3, I can see that
"X-Test: foo" gets set correctly, but I'm still seeing "Accept-
Encoding: gzip,deflate". Is this expected behavior? If so, is there a
reason why I can't change the Accept-Encoding value?
Thanks,

[jQuery] jQuery 1.3: Sweet upgrade, but can we use it?
New blog post, "jQuery 1.3: Sweet upgrade, but can we use it?" here: http://tr.im/751a The gist is that I'm concerned that jQuery is progressing faster than users are upgrading their browsers, making it increasingly difficult for web developers to sell the use of the library to management and clients. I *hope* I'm wrong because I would love to take full advantage of the improvements in 1.3. I welcome your comments. -Andrew - http://andrew.hedges.name/blog/
[jQuery] Re: why is this code inefficient?
I suggest giving jQuery a more specific context in which to search for
the elements in question. If the set of elements you want is (or can
be put) inside an element with an ID, that is the most efficient.
Selectors like:
$('#some-element .a-bunch-of-elements')
...are way faster than selectors like:
$('.a-bunch-of-elements')

[jQuery] Re: best/standard way to benchmark your own scripts?
Someone is bound to have a better answer than this, but to get you started with profiling, have a look at this page where I include some code to time my script execution: http://andrew.hedges.name/experiments/simple-templates-speed-test/ It wouldn't be much of a stretch to apply this same pattern to individual parts of the script to get a more detailed view. That said, I'm pretty sure there are (commercial?) tools out there that let you profile scripts in some detail. I'd be interested to know, too, if there are any that are free software. -Andrew On Sep 17, 4:14 pm, Alex Weber <[EMAIL PROTECTED]> wrote: > looking to find possible bottlenecks and basically optimize the hell > outta my js which relies heavily on jquery and the occasional > plugin... > > is there a more elegant and efficient way to do this than to toss a > few document.write()s at my code?? =P > > thanks!! > > -Alex

[jQuery] Simple Templates
Introducing a new jQuery plug-in, Simple Templates: http://andrew.hedges.name/blog/2008/09/03/introducing-jquery-simple-templates One thing I have missed from my Prototype days (shudder, I know!) is simple, built-in templating. I know there are other templating plugins, but I liked the Prototype syntax, so I wrote my own. It's only 1009 bytes! Enjoy! -Andrew
