Conversion between js objects and json objects

During js development, we often encounter the mutual conversion between JS objects and JSON-format data d. This article introduces the mutual conversion between js objects and json objects, for more information, see. 1. Convert JS objects to JSON

Process: Read the front-end page data, assemble it into a JS object, and pass it to python through jQuery's $. post () method.

Processing: reference A json2.js file and call the JSON. stringify () method.

Instance

Var data = new ob ject (); var json_data = JSON. stringify (data );

Read: python is easy here. It's okay to use dict_data = json. loads (json_data ).

Ii. Convert JSON into JS

Process: python assembles a dict data and transfers it to the front end in JSON format, or the front end directly reads the data in JSON format using the $. getJSON () method of jQuery.

Processing: Use jQuery's method $. parseJSON () to convert JSON-format data into JS objects.

Instance:

Var json_data = $. getJSON (); var data = $. parseJSON (json_data );

Reading: javascript image operations are unnecessary.

Here, python needs to convert the dictionary into JSON format data, just use the json. dumps () method.

PS: The json2.js file can be downloaded after being searched online.
