Asp.net&ajax&json-Dynamic Read data

Because before the WM Group made a delivery dashboard, about 3 weeks time,. NET also forget almost, Ajax and Highchart table is also learning, pretty laborious! Finally, I got it. Post a record.

1. foreground aspx page <Javascript> (the following AJAX code can be present and triggered in a JS event, which is included in the event code)

$.getjson ("Handler4.ashx", {"param": A, "param1": B}, function (data) {$.each (data, function (I, item) {    bar_version. Push (item["version"]);    Bar_value.push (item["Vamount"]);                   $.each (item, function (k, v) {                                                 });                       });

Param and param1 Pass the values of A and b into the background.

2. Ashx.cs-handler

string param = httpcontext.current.request["param"];

Pass the Param value into the handler CS background and serialize a list parameter JSON (using the Newtonsoft package)

stringStrjson = Newtonsoft.Json.JsonConvert.SerializeObject (_list);
Context. Response.Write (Strjson);

For more information about Newtonsoft:

3. incoming background JSON data to the foreground

$.getjson ("Handler4.ashx", {"param": A, "param1"function  (data) {// The Red data variable is a variable Strjson function from the background JSON format   ///through each function, the JSON-formatted data is read out.    Bar_version.push (item["version"]);    Bar_value.push (item["Vamount"]);           function ( K, v) {                                                 });                       });
