[jQuery] Re: Finding ID within Ajax response
Just a guess here - is it possible that jquery will not recognize
nodes that are loaded after the document is first rendered? Do you
need to rebind?

[jQuery] Re: General question regarding speed
Thanks for your thoughts. I have datasets of varying sizes from a few rows to several thousand. I do appreciate the flexibility that returning json gives me on the client side although I've done lots of server side manipulation in the past. Intuitively, this seems to mix apples and oranges though. Thanks again for your thoughts on the matter.

[jQuery] General question regarding speed
I am trying to figure the best way to maximize performance with data returned from ASP pages. Option one - return data in an HTML table. Let the host page's css format the table. Option two - return json data from the asp page and let the browser drop the data into a table and still let the host page do the final formatting. I guess the question is where the faster/least amount of processing time and transport of data is used. Other items of note - the application is an intranet where all users will have javascript enabled. Your collective wisdom is greatly appreciated.
[jQuery] Re: .getJSon
Thanks for the code snippet Josh. It's exactly what I was looking
for. Certainly load works as well. At this point I am trying to
understand various options for producing data on an intranet. In the
past I have written asp pages which format the HTML and then use ajax
(with or without jquery) to insert the dormatted data. I have assumed
that I might see a performance benefit by transporting raw data and
formatting it locally. I'm not sure if that holds true. Any
thoughts?

[jQuery] .getJSon
Sorry if this is a duplicate post - doesn't look like the last one
went through.
I've seen several examples of how to process json data with .each when
the field names come over with json. My data, howver, looks like the
following:
{"aaData": [
["1001-00-1535.000","Tenant Improvements"],
["1001-00-1558.000","Selling costs"],
["1001-00-1560.000","Financing Fees"],
["1001-00-1560.001","Financing Fees - Legal"],
["1001-00-1565.000","Lease Costs"],
["1001-00-1565.001","Lease Costs -Legal"],
["1001-00-1565.002","Lease Costs - Brokerage"],
["1001-00-1570.000","Legal Fees"]
]}
How would I drop this data into a table?
Thanks in advance for your help.
[jQuery] JSON Newbie
I'm new to jquery and json. I've looked at lots of examples of how to
process json data but they all seem to have field names that come
across in the data and are used in the foreach processing. My data
looks like this:
{"aaData": [
["1001-00-1535.000","Tenant Improvements"],
["1001-00-1558.000","Selling costs"],
["1001-00-1560.000","Financing Fees"],
["1001-00-1560.001","Financing Fees - Legal"],
["1001-00-5799.000","Bad Debt Expense"],
["1001-00-5800.000","Amortization"],
["1001-00-5805.000","Depreciation"],
["1001-00-.000","Suspense"]
]}
I'm trying to drop these two fields into table rows. Can someone
point me in the right direction as to how I reference the json data.
Thanks for your help.
[jQuery] Re: Form Plugin
Is there a way to make this dynamic?
I have ~ 100 lines that need to be written into a table of data which
a check box indicating status of a project (complete or not).
Each checkbox has an id="check1" or "check2" etc.
What I'm looking to do is to trigger a function that submits
ProcessThe Data.asp?ID=1 (which is done in the background without a
page refresh.
What you suggested works perfectly for submitting the entire form - I
think I want to submit a simple URL and have it process in the
background.

[jQuery] Form Plugin
Can someone please point me in the right direction? I am using the form plugin and it works great on a form submit action. Is there a way I can use it on a click event on a checkbox or onblur for a text field to immediately save the user's data? Thanks in advance for your help.
