How can I convert a JSON string to a JS object?

Json format requirements are simple. Any amount that appears must be enclosed in double quotation marks '{"name": "zs", "age": "3"}'.
Second, evalJSON () does not know where the above method is. jQuery provides a method to parse string as json. jQuery. parseJSON (str)

Convert JSON string to JS object

You call the evalJSON method because you have written a method, for example
String. prototype. evalJSON = function (){
Return eval ('+ this + ')');
}

Add this method to the front of js (you can also introduce it). This code is correct.
And all json string s can be called.
S. evalJSON () to get the corresponding json object
