    Hi redhookbaker,

    Thanks for the donation :-). The sAjaxSource property tells DataTables what page it should load from the web-server to get the JSON data. There are a number of different ways that you can deal with JSON data with DataTables:

    1. Javascript array - when you have the data already on the client-side - http://datatables.net/examples/data_sources/js_array.html

    2. Ajax file - load an JSON file (all data records in a single go) and have all the processing (sorting, filtering etc) done on the client-side: http://datatables.net/examples/data_sources/ajax.html

    3. Server-side processing - have all the processing done by the server (typically an SQL database or the like): http://datatables.net/examples/data_sources/server_side.html . This is great when you've got a large amount of data to display.

    Which is it that you are trying to use? If server-side processing, then your ASP script will need to reply to the request sent by DataTables as needed: http://www.datatables.net/usage/server-side . There are some sample scripts in this thread http://datatables.net/forums/comments.php?DiscussionID=937 - although I'm afraid I know nothing about ASP, so might not be a huge amount of help there.

    Regards,
    Allan

    Hi, Allan,

    Thanks for the quick reply. The external page I use is called testData.asp, when I run this page directly, here is what I have, I tried with/with out "", it does not show data. It also passes validation as a valid json..thanks

    [code]
    "{"aaData": [ ["1","demo1 ","demo2 ","","demo3 "], ["2","DEMO ","DEMO ","","DEMO "], ["3","demo Group ","demo group ","","winter "], ["5","ml llc ","ml llc1 ","","MLDirect "] ]}"
    [/code]

    oh, btw, I am getting data from SQL thanks
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    Right - so it looks like you are using option 2 - loading Ajax from a file and using client-side processing (not server-side).

    Try this then:

    [code]

    $(document).ready(function() {
    $('#example').dataTable( {
    "bProcessing": true,
    "sAjaxSource": "testData.asp"
    } );
    } );

    [/code]
    Note that filtering is on by default, so I've dropped that out.

    it is odd, if I plug http://www.datatables.net/examples/examples_support/server_processing.php in, it works, but using my asp page, it doesnt.

    The end result by running php and asp is the same, really strange...
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    Can you confirm if you want to use client-side, or server-side processing please? The JSON structure needed for each is different. Server-side processing needs a few more parameters.

    The link you gave is for server-side processing (option 3), but the JSON structure you gave is for client-side processing (option 2).

    Can you provide a link to the page please?

    this is the test data I am using, this is from a table from SQL, please have a look...thanks


    http://209.59.1.252/testdata.asp
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    Right - so what happens if you do:

    [code]

    $(document).ready(function() {
    $('#example').dataTable( {
    "bProcessing": true,
    "sAjaxSource": "testData.asp"
    } );
    } );

    [/code]

    I am getting "Processing..." but no data,
    but if I use http://209.59.1.252/testdata.asp, bServerSide set to True or False, i am getting
    DataTable Warning: Added data does not match number of known columns.....

    I am sorry to keep bugging you..thanks
  • redhookbakerredhookbaker Posts: 31Questions: 0Answers: 0
    I found out something is strange, if I use http://209.59.1.252/testdata.asp, it works fine.

    Exact same data, if I call the page name (testdata.asp), it does not work; if I use the local rurl (http://my-pc...../testdata.asp), it doesnt work......how weird is that? thx
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    I think you might be running into a XSS issue: http://en.wikipedia.org/wiki/Cross-site_scripting . You can load Ajax data from anything but the domain name which the original document is loaded in. So if you are loading from file:/// you are going to have a whole lot of problems. Or if loading from a site which isn't the same as where the document was loaded from...

    I just uploaded to another server and getting this error:

    any thoughts? thanks
  • redhookbakerredhookbaker Posts: 31Questions: 0Answers: 0
    looks like it is working now....I will post back....

    in the meantime, is there any documentation regarding the settings, such as the parameter list

    bProcessing
    bServerSide
    bFilter
    ...


    thanks
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    Yes indeed: http://datatables.net/usage/features

    Also this page ( http://datatables.net/usage/ ) defines the different data sources. It really is sounding like an XSS issue...

    How can I pass the parameter to the external page? using query string?

    thanks
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    Yes - just a query string on the URL to load would do. "testdata.asp?hello=world" for example.

    is there a way to "flush" the page becasue the same data source sometimes it works, sometimes it doesnt..thanks
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    Not really... The flush would be done on the server-side, not the client-side (unless you mean flush as in 'clear' - in which can fnClearTable would do). Perhaps looking at what the XHR is doing in Firebug would help.

    hi,

    I am going to try Java array, can you point me to the document/seetings for java array? thanks
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    I'm not sure what you mean. Where would you just the Java array and how? To output the JSON data?

    Allan
  • redhookbakerredhookbaker Posts: 31Questions: 0Answers: 0
    I am using the code based on this example
    http://datatables.net/examples/data_sources/js_array.html

    I get the data from SQL and parse it into java array and it works great....thanks

    I want to see if there are options like the server-side that can set bFilter=false, something like that...thanks
  • redhookbakerredhookbaker Posts: 31Questions: 0Answers: 0
    is there a way to disable Seach box in javaarray? thanks
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    I think you might be confusing Java with JavaScript in your above posts - hence the confusion :-). DataTables is entirely Javascript based and has nothing at all to do with Java.

    > I want to see if there are options like the server-side that can set bFilter=false, something like that...

    Yes - the same options apply as client-side processing. Using a JS array (in the example link you posted) is client-side processing. So bFilter:false will do it. Did you try that? That will also remove the filter box. All of the configuration parameters are listed in the 'Usage' section of this site.

    Thank you. I guess I have two more question (so far) sorry

    1. How can I change the sorting column color ?
    2. Is there a way to hightlight rows when mouse mover? thx
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    1. Yes - using CSS. 'sorting_1' is the class. Worth opening Firebug to look at what the mark up is.
    2. Again yes - using CSS :hover - http://www.google.com/search?q=css+%3Ahover

    Allan
  • redhookbakerredhookbaker Posts: 31Questions: 0Answers: 0
    it works out well...thanks

    last question, is it possible to add button on each row? thx
  • allanallan Posts: 63,407Questions: 1Answers: 10,452 Site admin
    Yes - just include the button like you would in a regular table: or whatever.
