js遍历json的key和value

<script>

var json = [{dd:\'SB\',AA:\'东东\',re1:123},{cccc:\'dd\',lk:\'1qw\'}];

for(var i=0,l=json.length;i<l;i++){

for(var key in json[i]){

alert(key+\':\'+json[i][key]);

}

}

</script>

 

    function setQueryVal() {
        var  argsObj={id:@ViewBag.RssTaskId}
        postBackCurrent("GetTask", argsObj, function (json) {
