Javascript-data parsing

{Code...} How should I parse the data returned by an API? PHP or js is used. For example, if I want to get totalPage, how can I write it?

res({"total" : 100, "totalPage" : 10, "page" : 2, "items" : ["data"]})

Similar to the data returned by a jsonp request
1. If the jquery class library is used, jsonp can be directly encoded using jquery ajax, which is relatively simple. There are a lot of online materials and it is no longer cumbersome.

2. If you manually write more code, perform the following operations:
The first step is to send a request and inject the returned content as a script.

Var script = document. createElement ('script'); script. setAttribute ('src', url); // The url here is the requested API // Add the script tag to the head and send the request document. getElementsByTagName ('head') [0]. appendChild (script );

Step 2: Define the imageresFunction. In this case, the data in res is the required object. You can operate data in this function.

Function res (data1 ){... // at this time, data1 is {"total": 100, "totalPage": 10, "page": 2, "items": ["data"]}

First:
Var string = 'res ({"total": 100, "totalPage": 10, "page": 2, "items": ["data"]}) ';
Var response = JSON. parse (string. substr (4, string. length-5 ));
