js json object Convert

 

一、JS对象转换成为JSON

流程:读取前端页面数据,组装成为JS对象,并通过jQuery的$.post()方法传递给python。

处理:引用一个json2.js文件,调用JSON.stringify()方法。

实例

<code class="javascript">var data = new ob ject();
var json_data = JSON.stringify(data);</code>
Copy after login

读取:python这里就很简单了,用dict_data = json.loads(json_data)就OK了

 

二、JSON转换成为JS

流程:python组装一个dict数据并转成JSON格式传递给前端,或者前端通过jQuery的$.getJSON()方法直接读取这个JSON格式的数据

处理:用jQuery的一个方法$.parseJSON()将JSON格式的数据转成JS对象。

实例:

<code class="javascript">var json_data = $.getJSON();
var data = $.parseJSON(json_data);</code>
Copy after login

读取:JS对像的操作就不必多说了

这里,python要把字典转换成JSON格式数据,用json.dumps()这个方法就行了

PS:json2.js这个文件在网上搜一下就能下载到。
