JS 循环遍历JSON数据

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： 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：

view plaincopy to clipboardprint?
01.var data=[{name:"a",age:12},{name:"b",age:11},{name:"c",age:13},{name:"d",age:14}];
02.      for(var o in data){
03.        alert(o);
04.        alert(data[o]);
05.        alert("text:"+data[o].name+" value:"+data[o].age );
06.      }
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

view plaincopy to clipboardprint?
01.<script type="text/javascript">
02.function text(){
03. var json = {"options":"[{\"text\":\"王家湾\",\"value\":\"9\"},{\"text\":\"李家湾\",\"value\":\"10\"},{\"text\":\"邵家湾\",\"value\":\"13\"}]"}
04. json = eval(json.options)
05. for(var i=0; i<json.length; i++)
06. {
07.     alert(json[i].text+" " + json[i].value)
08. }
09.}
10.</script>
