js对象和json对象互相转换
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$.post()方法传递给python。
处理:引用一个json2.js文件,调用JSON.stringify()方法。
实例
<code class="javascript">var data = new ob ject(); var json_data = JSON.stringify(data);</code>
读取:python这里就很简单了,用dict_data = json.loads(json_data)就OK了
二、JSON转换成为JS
流程:python组装一个dict数据并转成JSON格式传递给前端,或者前端通过jQuery的$.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>
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。
