jQuery function call method

4 common request methods of ajax in jQuery:

1 .$.ajax() returns the XMLHttpRequest object it created.
$.ajax() has only one parameter: the parameter key / value object, which contains the configuration and callback function information.
If the dataType option is specified, make sure that the server returns the correct MIME information .
example

$.ajax({
        type: "post",
        dataType: "html",
        url: '/Resources/GetList.ashx',
        data: dataurl,
        success: function (data) {
            if (data != "") {
                $("#pager").pager({ pagenumber: pagenumber, pagecount: data.split("$$")[1], buttonClickCallback: PageClick });
                $("#anhtml").html(data.split("$$")[0]);

            }
        }
    });

 
2. Load information via remote HTTP GET request. This is a simple GET request function to replace the complex $.ajax. The callback function can be called when the request is successful. But execute the function on error, use
$.ajax. example:

$.get("test.cgi", { name: "liu'jun", time: "2pm" },
  function(data){
    alert("Data Loaded: " + data);
  });

  3. Load information via remote HTTP POST request. This is a simple POST request function to replace the complex $.ajax. The callback function can be called when the request is successful. If you need to execute a function on error, use $.ajax. example

$.post("/Resources/addfriend.ashx", { "fid": fids, "fname": fnames, "tuid": tuids, "tuname": tunames },
liu jun function (data) {
        if (data == "ok") {
            alert("Added successfully!");
        }
    })

4. Load JSON data via HTTP GET request. example

$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?",
function(data){
  $.each(data.items, function(i,item){
    $("<img/>").attr("src", item.media.m).appendTo("#images");
    if ( i == 3 ) return false;
  });
});
