//---------for用来遍历数组对象
    var i,myArr = ["a","b","c"];
    for (var i = 0; i < myArr.length; i++) {
        console.log(i+":"+myArr[i]);
    };
    //---------for-in 用来遍历非数组对象
方法一、
    var man ={"1":"a","2":"b","3":"c"};
    for(var i in man) {
        console.log(i,":",man[i]);
    } 
方法二、

　　var man ={"1":"a","2":"b","3":"c"};

　　$.each(man, function(i){
　　　　console.log(i,":",man[i]);
　　});
