The method by which JS loops through JSON data

JSON data such as: {" options ":" [{/ "text/" :" Wang Jiawan /, / / "value" : / 9 "/"}, {/ "text/" :" the lijiawan /, "/" value
E / 10: "/"/"}, {" text / : "/" shao house bay /, "/" value/" : / 13 "/"}] "}

Js can be written as:

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 ); 
}

or

<script type="text/javascript"> 
function text(){ 
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>
