HomeBackend DevelopmentPHP Tutorialjavascript - 三级json数据去掉属性名的引号

php 从数据库中获取数据 处理之后 $this->ajaxReturn($data);
得到以下数据,但js端要的是 name和sub 去掉引号的数据,{name: "北京市"}
在js端 typeof 类型是 object
在Php处理方便还是js处理方便,
分别是怎么处理的。

<code>[
    {
      "name": "北京市",
      "sub": [
        {
          "name": "东城区"

php返回json数据字符串,js将返回的json字符串解析为json对象就可以

ajax请求设置dataType:'josn'
php返回的时候json_encode处理下
前端接收到的数据就是object了

有没有引号并不影响它作为对象的属性。

将json转换为js对象再去操作,JSON.parseJSON(data)


data=JSON.parse(data);
jQuery.each(data, function(k,v) {});
并不会取到“”?
