如何更改Ajax请求类型和数据

Question

I'm using jQuery DataTables and I have a table that is loading data via an Ajax request. The Ajax source is being set at initialization.

However, I would now like to change the request type to a POST and include a data object before I force an Ajax reload.

I am doing something like this, but it doesn't work:

dt.ajax.type = 'POST';
dt.ajax.data = {<some data here>};
dt.ajax.reload();

I am only able to change the Ajax source URL, but that doesn't need to change.

You can use ajax option to define a function to call $.ajax method as shown below:

$('#example').dataTable( {
  "ajax": function (data, callback, settings) {
      if(some_condition){
         data.param1 = "A";
         data.param2 = "B";
      }

      $.ajax( {
         "dataType": "json", 
         "type": (some_condition) ? "GET" : "POST", 
         "url": "/json.php", 
         "data": data, 
         "success": callback
      });
   }
});

This function will be called on initialization and every time you call ajax.reload() .
