Hello, I used DataTables heavily in the past, but I'm new 1.10. I love it so far and was excited to get on a project that could make use of this awesome plugin. Anyways, my question is can I overwrite data sent in my ajax call? I don't really need all of the info the default sends and I already have a ajax call that works. I know I've done something similar in the past with older versions of DataTables but don't remember what because I can't look at the code any more, it's been awhile, and with the new version changes.
Example:
I have the following ajax call that works:
return $.ajax({
type: 'POST',
contentType: 'application/json; charset=utf-8',
url: "Service/GetStuff",
data: getCriteria(),
dataType: "json",
cache: false
});
Where getCriteria function is something like:
var criteria = {
"Model": $("#ModelDl").val(),
"Year": $("#YearDl").val(),
"Vendor": $("#VendorDl").val(),
"PageStart": pageStart, //I'm grabbing page and sort info from page.info() and sort.info()
"PageEnd": pageEnd,
"Sort": sort,
"SortDirection": sortDirection
}
return '{"criteria":' + JSON.stringify(criteria) + ' }';
This hits a WCF service.
So, I thought I could easily just jam the above ajax call into the DataTable ajax, modify the WCF service to return what DataTables is expecting like this:
table = $("#ResultsTbl").DataTable({
"order": [[0, "asc"]],
"pageLength": 50,
"serverSide": true,
"ajax": {
type: 'POST',
contentType: 'application/json; charset=utf-8',
url: "Service/GetStuff",
data: getCriteria(),
dataType: "json",
cache: false
},
"columns": [
{ "data": "ItemNumber" },
{ "data": "DownloadDateTime" },
{ "data": "Size" }
]
});
But this immediately throws "Object doesn't support this property or method" in MicrosoftAjax.js. It says a "replace" function is undefined. Pretty vague issue, I know, but is this not possible or am I doing it wrong? Thanks in advance for any help.

So, I looked into
ajax.dataSrc, and it sounded like what I'm suppose to be using for this. I put it in like so:It now hits the WCF service, but it's sending the default DataTable data, which is not what the service is expecting. It's not even including
ajax.dataSrc, so I must not fully understand it's function.Maybe I should get another cup of coffee, this worked and should have been my first attempt/thought:
Oops, sorry, everyone. Thanks again!
