code:
//
function Get_MyData (para1)
{
var parameters = AjaxServer.aspx?para1= + para1;
$.getJSON(parameters, function(data) {
// error handle
if (!onError(data)) return ;
//
var retList = [];
$.each(data.data, function(i, xy) {
retList .push(option value=');
retList .push(xy.id);
retList .push(');
retList .push(xy.name);
retList .push(/option)
});
return str = retList .join();
});
}
// test function
function test_ajax()
{
var str = Get_MyData(1);
alert (str);

[jQuery] thickbox bring my IE window back
Hi, I just found this problem, I have a asp.net application, at client side, I use thickbox to show some picture in a modal dialog box, kind of. generally, when you click a link, my code will show a modal with pictures in it. It works fine till today, when I click the link, whole IE window go under other windows (Window Explorer, Outlook, ...). This only happen if there is only tab in the IE. I use jQuery 1.2.6 and thickbox with modification. What could be the reason? Thanks, Wes

[jQuery] select input in td not wokring, and disabled textbox centered
Hi,
I have this problem. check the code below
when first checkbox unchecked will disable 2nd checkbox and textbox;
when 2nd checkbox unchecked will disable textbox.
now 2nd checkbox works just fine, but I have problem to make 1st one
work.
I use
$(this).parent().nextAll().attr('disabled', !$
(this).is(':checked'));
which will disable 2nd checkbox and textbox, but I still can enter
in textbox, I knew it will disable TD instead of the INPUT inside.
I also try
$(this).parent().find('input').attr('disabled', !$
(this).is(':checked'));
$(this).parent().nextAll('input').attr('disabled', !$
(this).is(':checked'));
none of them works.
How I can make this work?
Thank you,
Wes

Any way... my question would be why you are using a string in the first
place?
A possible smarter alternative is to use a DOM object in memory.
Something like this:
var myTable = $(table/table);
for (var x = 0; x json.length; x++) {
var row = $(tr/tr);
row.append(tdmy stuff: + json[x] + /td);
myTable.append(row);
}
$(body).append(myTable);
Now, this will do nothing for the sheer volume of data you are dealing
with. But it gets rid of the string and creates DOM objects
immediately. So, the overall processing *should* be a little faster.
The other option is to NOT show so much data, but to introduce paging,
or a smart scroll that will only load data as needed... But dealing
with large volumes are always troublesome. a 7 or 8 second turnaround
isn't tooo bad. I have one page that is closer to 30 seconds (customer
asked for it though - wider date range = more data = more time). The
point is that when large volumes are being dealt with, a delay is
expected. We *should* try to eliminate the delays where we can, but

Hi
I just start use jQuery about 2 month ago, so please bear with me if
I ask some question which already answered.
I'm working a ajax project, I use JSON to get result from server and
then generate a table on the fly. the problem I have is, my end table
string is huge, length is 935895.
$(#m).html( str ); take
about 7000-8000ms
var m = document.getElementById(m);
m.innerHTML = str; tabke about 2000-3000ms
m is div, str is my test string.
Is there something wrong? How I can improve it?
Thank you very much.
[jQuery] round corner slideout
Hi, I just start use jQuery for about 3 month. It really save me a lot of work. Now I have this problem, I have a div with 4 round corner. I made by picture. there are all kind elements inside, dropdown list, button, list, textarea, checkbox, ... Now we decide to change it to this, initially it will collapse with only title show up, when you click a image in the title, it will expand to full size. It will save a lot space for beneath datagrid. the problem is, we would like to still show 4 round corner when it collapse as title, and expand as full size. I'm looking in the corner plugin. How to implment it? I really appreciate your help Thank you very much and have a nice weekend. Wes
