[Proto-Scripty] Execute JavaScript within HTML Response to Ajax Request
Via Google search, I found this answer today here:
http://stackoverflow.com/questions/278122/how-to-force-javascript-to-execute-within-html-response-to-ajax-request
I have it half working. What I mean is, my response text comes back
and updates my div perfectly with the HTML when evalScripts: false,
however the scripts within the HTML are of course not executed. When I
set evalScripts: true, then the ONLY thing that executes is the
scripts and it outputs it directly to the page instead of loading it
into the div.
I think the problem is that the scripts I am trying to execute are
likely document.writes generated by the Maani charts (http://
www.maani.us/xml_charts/index.php) and so instead of loading text into
the div, the executed scripts just write themselves out to the
browser.
Any ideas on how I can fix this? Here's my Prototype code:
function runCalcs() {
var request = new Ajax.Updater
(
result_tab_frame,ajax_runCalcs.asp,
{
method: get,
evalScripts: true,
onSuccess: function () {
document.getElementById(loading).className = clsHide;
}
}
);
}

[Proto-Scripty] Re: how to update a function with a remote call
Hey there,
Wanted to say thanks for all your help here.
The links especially.
I am still very new at all this and it's a lot to get my head around.
That site is excellent.

Hi,
You're taking the return value of `new Ajax.Request` and using it to
set the contents of `weather_table_one`. The return value of `new
Ajax.Request` is (of course) an Ajax.Request object. It's really worth
reading the documentation.
If you want to use the contents of the resource that the Ajax.Request
loads, you need to use the onSuccess callback:
function replace_weather_table(){
zoomy = map.getZoom();
new Ajax.Request('/weather/update_weather_tables?zoom='+zoomy,
onSuccess: function(response) {
weather_table_one.setContents(response.responseText);
}
});
};
Note that by default, Ajax requests are asynchronous, and so the
update will happen at some point after the `replace_weather_table`
function returns. You probably want to handle failures as well.

Sorry, I missed out an opening bracket. Should have been:
function replace_weather_table(){
zoomy = map.getZoom();
new Ajax.Request('/weather/update_weather_tables?zoom='+zoomy, {

this was missing

[Proto-Scripty] AJAX callbacks are not executed atomically?
I have several lines of code that I want to run atomically (no context
switches to other code). Please look at the following barebones
example that illustrates the issue:
//=
function doAjax() {
console.info('making request');
new Ajax.Request(
url, {
onSuccess: function() {
console.info('success');
},
onFailure: function() {
console.info('failure');
},
onComplete: function() {
console.info('complete');
}
}
);
}
doAjax();
doAjax();
//=
If the processor is faster than the network, I expect the output to
be :
making request
making request
success
complete
success
complete
However, under certain conditions, success+complete is sometimes not
atomic. Here's some output that I have seen:
(A) making request
(A) success
(B) making request
(A) complete
(B) success
(B) complete
This is against my expectations and breaks my code logic - the website
fails to function when complete does not IMMEDIATELY follow success.
Can someone shed some light on why this is happening? I thought AJAX
is only asynchronous while waiting for the server and should become
synchronous as it's executing the callback code...

If you want a() to finish before b() and b() to finish before c() then you
will have to daisy chain in the onComplete code.

[Proto-Scripty] Re: AJAX callbacks are not executed atomically?
I believe I solved the problem. I had a queue of work orders. One of
these work orders queued up another work order, so it was a nested
AJAX request - BAD IDEA!

Re: [Proto-Scripty] Re: AJAX callbacks are not executed atomically?
Same difference.
Since the AJAX calls are Async you have no control over what gets completed
first or what gets interrupted by what.
If script a does a complex query taking 2.2 seconds and returns a large data
set while script b does a simple query that takes .02 seconds and returns
100 bytes, script b will almost certainly interrupt script a.
You have two options (as far as I know), you can daisy chain the calls and
thereby guarantee the call/completion order or you can create your own
semaphore process and lock (sleep) the onComplete of script b until script a
clears the i'm done flag.
