jQuery解析json格式数据示例

var arr1 = [ "one", "two", "three", "four", "five" ];
$.each(arr1, function(){
  alert(this);
});

var arr2 = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
$.each(arr2, function(i, item){
  alert(item[0]);
});

var obj = { one:1, two:2, three:3, four:4, five:5 };
$.each(obj, function(key, val) {
  alert(obj[key]);
});

//json格式
var param = [{'subJobClass':'com.sample.quartz.MyJob','subJobMethod':'hello','taskParam':[{'username':'张三'},{'age':'28'},{'tel':'15818821129'}]}];
//设置参数值
if(param.length>0){
  alert(param[0].subJobClass);
  alert(param[0].subJobMethod);
  var taskParam = param[0].taskParam ;
  //遍历任务参数数组
  jQuery.each(taskParam,function(i, item){
    //解析单个任务参数
    jQuery.each(item ,function(key){
      alert(key);//key
            alert(item[key]);//value
          });
  });
}
