[jQuery] How can I make sure one AJAX call returns before another?
I have several AJAX calls. Most of them retrieve values for drop-down lists and one fills in the data. Of course, unless the drop down lists are fully loaded, the data filler doesn't select them properly. Is there anyway to trigger the data filler after they are complete with more sophistication than setTimeout? BTW, I've tried ajaxStop but that causes an infinite loop since the data filler triggers it again. Thanks!
[jQuery] Ajax not sending data correctly when it's a variable, but perfect when it the value is typed in instead.
I have a simple AJAX call:
$.ajax({
url: setBMBJSONString.php,
data: stringJSON.toString(),
success: function(rdata) {
//var resp = eval('(' + rdata + ')');
$(body).append(rdata);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
var e = XMLHttpRequest;
for (var key in e) {
$(body).append(key + : + e[key] + br /);
}
}
});
That won't work, the data doesn't get to the webservice that way. But
if I do this instead:
$.ajax({
url: setBMBJSONString.php,
data:
{prefix:Bishop,fname:Nkulu,mname:Ntanda,lname:Ntambo,suffix:Esq.,relation:},
success: function(rdata) {
//var resp = eval('(' + rdata + ')');
$(body).append(rdata);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
var e = XMLHttpRequest;
for (var key in e) {
$(body).append(key + : + e[key] + br /);
}
}
});
Everything works fine! All I did was print out stringJSON and copy it
and paste it in there. What's going on? For obvious reasons I need
to use a variable there.
[jQuery] Re: Ajax not sending data correctly when it's a variable, but perfect when it the value is typed in instead.
Yes, same result. I added the toString() just in case. I've
discovered more. Here is the code right before it that makes the
variable:
var OBJ = {};
$(:input).each( function () {
OBJ[$(this).attr(name)] = $(this).val();
});
var stringJSON = JSON.stringify(OBJ);
Now if I pass OBJ to the data: parameter it works! Unfortunately,
double quotes make it break, etc. so I really need to have it scrubbed
before sending it, which JSON.stringify is supposed to do. So it
looks like it doesn't like strings. Which is weird because with
a .NET backend, it HAS to be a string. I wish I new more about what
was going on there.
How can I do this? Do I have to write my own scrubbing?? And why
doesn't it like strings?

You're right, the values transferred fine without doing anything to
them.
Could you show me a method that will accept Request.Params just like
I'm trying to get this data?

Which is totally not true .NET can handle JSON in (via
Request.Params) and JSON out (using the excellent JSON.net class by
James Newton King)
anyways, If you have
var OBJ = {};
$(:input).each( function () {
OBJ[$(this).attr(name)] = $(this).val();
});
$.ajax({
url: setBMBJSONString.php,
data: OBJ,
.. etc etc...
});
Then the receiving page, no matter if it's php. .NET, whatever, will,
well *should*, see properly encoded/escaped Key/Value pairs as either
QueryString or Form pairs (depending on if the $.ajax call does GET or
POST) watch the call in firebug and keep an eye on the Params or
Post tab in the Console and you can confirm/deny this
You shouldn't need to scrub those at all... if it's anything else,
then you aren't coding all this correctly... perhaps if you get a live
and testable page up for others to dissect?

[jQuery] Simple question about Radio Buttons
Why does this line of code not work for the radio button? if ($(this).attr(type) == radio) alert($(this).checked); I get 6 alert boxes (I have 6 Radio Buttons) and the alert says undefined every time. But half of them should be true and half should be false. Am I doing something wrong? here are two of the radios: input name=recvd_loan type=radio value=1 / Yes input name=recvd_loan type=radio value=0 / No Thanks!
[jQuery] Re: Simple question about Radio Buttons
Well I fixed it, I had to use: $(this).attr(checked) to get the value. Should I have known this?

[jQuery] Re: borders work fine with all browsers except IE7
Ok, point taken, but I have a CSS file, a JS file, and an XHTML files, each are about 300 lines. That's a little too much for this textbox, so how can I post this info for you to see? It's not a public website. Is there some online service that hosts text displaying versions of this stuff?

jQuery's serialize method does not create JSON strings. It creates
URL-encoded strings, as you discovered.

Any idea what's wrong? Can this be done this way? Is there a way I
can serialize it to a JSON formatted string instead?
Thanks.

[jQuery] Re: $.ajax isn't parsing JSON object properly
Says undefined, so it's not accessing the properties properly with an
rdata.guid for instance.
Turns out, I need to eval the string which I couldn't get right at
first. I tried eval(rdata); but it failed.
However, when I tried eval('(' + rdata + ')') it worked fine! So why
is this how I have to eval it? It would help me to understand how to
use it.
Thanks!

Do you get an error?
Not sure how to access the values?
Something else?
The first result is valid JSON (to see, just paste it into the
excellent JSON Viewer you can download athttp://www.codeplex.com/JsonViewer)
But you don't provide enough information on what's wrong, so it's
difficult to tell you what's right
[jQuery] .unbind hover doesn't work
To unbind the above example use:
$(#nav1).unbind('mouseenter mouseleave');
This is what the documentation says, but it doesn't remove the hover
event. Do I have to do something else?
Thanks.
