JS 循環遍歷JSON數據

JSON數據如：{"options":"[{/"text/":/"王家灣/",/"value/":/"9/"},{/"text/":/"李家灣/",/"valu
e/":/"10/"},{/"text/":/"邵家灣/",/"value/":/"13/"}]"}

用js能夠寫成：

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/":/"王家灣/",/"value/":/"9/"},{/"text/":/"李家灣/",/"value/":/"10/"},{/"text/":/"邵家灣/",/"value/":/"13/"}]"} 
  json = eval(json.options)
  for(var i=0; i<json.length; i++)
  {
     alert(json[i].text+" " + json[i].value)
  }
}
</script>
