This article illustrates the JS object and json string format conversion method, to share for your reference. The specific implementation method is as follows:

<head>

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <title></title>

    <script type="text/javascript">

        var obj = new Object();

        obj.Name = " Eight quit "

        obj.Age = 500;
        //Object 
 is defined as a literal
        var obj1 = { "Name": " Eight quit ", "Age": "500" };

        var arr = [{ "Name": " Eight quit ", "Age": "500" }, { "Name": " Eight quit 1", "Age": "1000" }];
        //JSON format: the literal representation of JSON is stored as a string as a JSON format string 

        var str = '{ "Name": " Eight quit ", "Age": "500" }';

        var jsonstrarr = '[{ "Name": " Eight quit ", "Age": "500" }, { "Name": " Eight quit 1", "Age": "1000" }];';

        

        //Converts the json string to a js object (array) 

        var resobj = JSON.parse(str);

        alert(resobj.Name);
    </script>

</head>

<body>

</body>

</html>

Interconversion of js objects and json objects in the front end:

I. JS object is converted into JSON

Handling: refers to a json2.js file and calls the json.stringify () method. Such as:

var data = new Object();

var json_data = JSON.stringify(data);

PS: json2.js this file can be downloaded by searching the Internet.

Second, JSON is converted into JS

1. Processing: turn json-formatted data into JS objects using $.parsejson (), a method of jQuery. Such as:

var json_data = $.getJSON();

var data = $.parseJSON(json_data);

(can be used to convert js arrays)

2. Method to convert json into js object:

var json = eval('(' + result + ')');

With the above expression, you've parsed the server-side response to the client's json-formatted string into a Json (formatted) object called "Json" that can be accessed by "json." or "Json []."

Transfer of js object and json object in the background:

The.net Framework 4 in the System. The Runtime. Serialization. The JavaScriptSerializer class is used to serialize and deserialize data

Example:

//Set the param antisequence column list 

List<ApplyPart> _ApplyPart = new JavaScriptSerializer().Deserialize<List<ApplyPart>>(param);
