JSON数据如：{"options":"[{/"text/":/"王家湾/",/"value/":/"9/"},{/"text/":/"李家湾/",/"valu
e/":/"10/"},{/"text/":/"邵家湾/",/"value/":/"13/"}]"}

JSON数据如：{"options":"[{/"text/":/"王家湾/",/"value/":/"9/"},{/"text/":/"李家湾/",/"valu
e/":/"10/"},{/"text/":/"邵家湾/",/"value/":/"13/"}]"}
用js可以写成：
var data=[{name:"a",age:12},{name:"b",age:11},{name:"c",age:13},{name:"d",age:14}];
for(var o in data){
alert(o);
alert(data[o]);
alert("text:"+data[o].name+" value:"+data[o].age );
}
或是
<script type="text/javascript">
function text(){
var json = {"options":"[{/"text/":/"王家湾/",/"value/":/"9/"},{
/"text/":/"李家湾/",/"value/":/"10/"},{/"text/":/"邵家湾/",/"value/":/"13/"}]"}
json = eval(json.options)
for(var i=0; i<json.length; i++)
{
alert(json[i].text+" " + json[i].value)
}
}
</script>
e/":/"10/"},{/"text/":/"邵家湾/",/"value/":/"13/"}]"}
