How to read JSON in js

Source: Internet
Author: User

I have two methods for reading JSON in js:
Method 1: function construction definition method return
Var strJSON = "{name: 'json name'}"; // obtain the json
Var obj = new Function ("return" + strJSON) (); // converted JSON object
Alert (obj. name); // json name

Method 2: The famous eval function in js
Var strJSON = "{name: 'json name'}"; // obtain the json
Var obj = eval ("(" + strJSON + ")"); // converted JSON object
Alert (obj. name); // json name

Note that the object expression {'name': 'json name'} must be expanded with "()". Otherwise
Var strJSON = "{name: 'json name '}";
Var obj = eval (strJSON );
Alert (obj. constructor); // String constructor
Alert (obj. name); // undefine
You must extend the object expression to eval for execution to generate an anonymous object!
