小弟不太懂ＪＳ，代码是从网上找的，参考了#contentArea，给＃mylist 赋值，希望得到累加的字符串，结果运行后得到的是最后一组字符串，前面的字符串没有累加进来．．．哪里错了，请教大神　




contentListInit: function () {
                var betStorage = $.fn.check.getLocalBetArray();
                var zscount = 0;
                var countamount = 0;
                var c = 0, lx = 1;
                $("#contentArea").empty();
                $("#mylist").empty();
                if (betStorage.length > 0) {
                    $(".nullNotice").hide();
                    $.each(betStorage, function (index) {
                        var html = "";
                        var hlist = "";　　　//声明hlist
                        var guid = betStorage[index].Guid;
                        var betType = betStorage[index].BetType.toLowerCase();
                        var betContent = betStorage[index].Content;
                        var typename = $.fn.check.playWays[betType].name;
                        var betcount = betStorage[index].BetCount;
                        var type = $.fn.check.playWays[betType].play;
                        if (type.indexOf('dt') < 0) {//　
                            if (-1 != betContent.indexOf('#')) {
                                typename = typename + "dt";
                            }
                        }
                        if ('l3' == type || 'l2' == type || -1 != type.indexOf('l4') || -1 != type.indexOf('l5')) {

写了一大驼，估计不耗个半小时的脑力是看不明白你写的。你应该把你不懂的东西拿出来重新写一个小点的程序。
从整体的角度看了看，你的程序不可以成功运行的：
你写了个大函数，看最后一行就知道，没有调用这个函数。

  我已经红色标记标出　　　其实mylist的内容就是#contentArea中的一部分，字符串累加的．．．．比如有三个字符串，ＡＡＡ，ＢＢＢ，ＣＣＣ　#contentArea正常显示是aaabbbccc，但mylist显示的就是ccc   

你自己用浏览器跑一下看看能不能运行。有太多太多的错误在里面。

你JavaScript语法知识太渣，最好不要学jQuery，先把JavaScript学好再玩jQuery吧

你也许从一个完整的程序中选了这个一小段程序，鬼才能看的明白

可以运行，就是累加的结果不是　我要的．

累加而已，不需要看整个程序吧．．．　　参考了#contentArea，给＃mylist 赋值　，参数都相同的，通过这个涵数．．#contentArea显示的是正确值，mylist只显示最后的字符串．．．我估计你都没仔细看

已经解决
