{"options":"[{"text":" Wang Jiawan ","value":"9"},{"text":" The lijiawan ","valu
e":"10"},{"text":" Shao house bay ","value":"13"}]"}
<script type="text/javascript">
    var d1 =[{"text":" Wang Jiawan ","value":"9"},{"text":" The lijiawan ","value":"10"},{"text":" Shao house bay ","value":"13"}];
    $(d1).each(function(){
        if(
        alert(this.text);
    });
</script>

 

Javascript does the traversal.

<script type="text/javascript">
  var json = {"options":"[{"text":" Wang Jiawan ","value":"9"},{"text":" The lijiawan ", "value":"10"},{"text":" Shao house bay ","value":"13"}]"}
  json = eval(json.options)
  for(var i=0; i<json.length; i++)
  {
     alert(json[i].text+" " + json[i].value)
  }
</script>

 

Convert to a json object if you started with string json. Use the eval (); For example, var json = eval(strJson);
