这个json 对象是后台一个数给生成的。

                (

                    [全部] => 

                    [动作] => Action

                )



            [1] => Array

                (

                    [全部] =>

                    [日本] => 12

                    [韩国] => 1

                    [美国] => 2

                    [英国] => 5

                    [其他] => *

                )

我主要是现实二个 select 控件动态加载后台传过来的数据内容。键值为select的名字，值为select的 value

还请指点一下，我应该怎么做一上。

看样子你对 jq 也并不熟悉，拿了能用吗？

JS 问题请到 javascript 版面求解

另外你还需说明：你打算使用原生的 js 语句，还是使用 jquery、extjs 等框架实现。不然给了你代码你也不能用

js 中遍历json对象：

for(var obj in jsonObj){
alert(jsonObj.obj);
}

php中。可json_decode($jsonObj,true);
然后遍历数组

将jsonList传到后端用php解决：



<?php

$jsonList ='[{"\u5168\u90e8":null,"\u52a8\u4f5c":"Action","\u7231\u60c5":"Romance","\u79d1\u5e7b":"Sci-Fi","\u707e\u96be":"Disaster","\u6050\u6016":"Horror","\u60ac\u7591":"Mystery","\u9b54\u5e7b":"Fantasy","\u6218\u4e89":"War","\u7f6a\u6848":"Crime","\u60ca\u609a":"Thriller","\u52a8\u753b":"Animation","\u4f26\u7406":"Ethics","\u7eaa\u5f55":"Documentary","\u5267\u60c5":"Drama"},{"\u5168\u90e8":false,"\u4e2d\u56fd\u5185\u5730":"8","\u53f0\u6e7e":"4","\u65e5\u672c":"12","\u97e9\u56fd":"1","\u7f8e\u56fd":"2","\u82f1\u56fd":"5","\u6cd5\u56fd":"13","\u897f\u73ed\u7259":"19","\u52a0\u62ff\u5927":"24","\u5fb7\u56fd":"6","\u6cf0\u56fd":"20","\u5370\u5ea6":"39","\u610f\u5927\u5229":"9","\u5176\u4ed6":"*"}]';

$obj = json_decode($jsonList);

?>

<select name='sele'>

<?php foreach($obj[0] as $k => $v){ ?>

<option value='<?=$v?>'><?=$k?></option>

<?php } ?>

</select>

我用中文的原因是因为

中文每一个值都有，相反，就会出现没有键值，但是又有值的问题，到时候，不好调用，

我这个怎么调用呢？？

$.getJSON(url, function(json){
$.each(json, function(i, field){
if(field.usernum == qjnum ){
showbox(html);
return false;
}
});
});

url js

{"key_1": {"usernum": 5,"price": 900,"rongliang": "1G","fujian": "50M","chuanzhen": 1,"qiyewangpan": 5,"chaodafujian": "","eim": "","gerenwangpan": "","suishenyou": ""}}

var res_obj=eval("("+res+")");
然后遍历之...
for(var i=0;i<res_obj.length;i++){
alert(res_obj[i].id);
}
或者jqeury遍历之
$.each(res_obj,function()){
alert(this.res+" "+this.id)
}
不知道对不对！
