json 总结

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：

[javascript] view
plaincopyprint?

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

[javascript] view
plaincopyprint?

<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>
