$(document).ready(function(){

	//fblog-add1						 
    $("#fblog-add1").click(function() {

	});
    $("#fblog-reduce1").click(function() {
        if ($(".selectl-inner-sizel dl").size() > 1) {
			I = I - 1;
              $(".selectl-inner-sizel dl:last-child").remove();
            };
    });
});

效果大概为点一次 添加一批内容，而次添加的内容都要计数，比如最开始I=1，那么第一次点击添加内容的时候，getElementById(Size)中，SIZE的值应该是size2_id，以此类推，第二次点击，getElementById(Size)中SIZE的值应该是size3_id，我想利用这种办法跟几个HIDDEN的文本框对应，但是实际情况是点了几次添加后，前面已经生成的所有getElementById(Size)中，SIZE的内容都变成了最后一次的SIZE的值，如何解决这个问题？

document.getElementById(Size)这种变为组合的
document.getElementById('+Size+')

        $("#fblog-add1").click(function () {
            if ($(".selectl-inner-sizel dl").size() < 5) {
                I = I + 1;
                Size = "Size" + I + "_Id";
                alert(Size);
                $('.selectl-inner-sizel').append(
                '<dl class="frame-sel-filed pdt10">' +
                '<dd class="frame-sel-dd-01">文胸尺码</dd>' +
                '<dd class="select-box"><span>请选择...</span>' +
                '<ul class="select-ul">' +
                '<li class="bg-fff" onclick="javascript:document.getElementById('+Size+').value = this.innerHTML;">32A</li>' + '<li onclick="javascript:document.getElementById('+Size+').value = this.innerHTML;">32B</li>' + '<li class="bg-fff" onclick="javascript:document.getElementById('+Size+').value = this.innerHTML;">32C</li>' +
                '<li onclick="javascript:document.getElementById('+Size+').value = this.innerHTML;">32D</li>' + '<li class="bg-fff" onclick="javascript:document.getElementById('+Size+').value = this.innerHTML;">32DD</li>' + '<li onclick="javascript:document.getElementById('+Size+').value = this.innerHTML;">34A</li>' + '<li class="bg-fff" onclick="javascript:document.getElementById('+Size+').value = this.innerHTML;">34B</li>' +

                '</ul>' + '</dd>' + '</dl>');
            };
        });

试过了 没有用 看来好像我本身这样的需求就比较山寨？不如直接获取<dd class="select-box"><span>请选择...</span> 这里的值？

[未知数]

document.getElementById(Size).value
你每一个节点点击事件用的都是同一个变量，你还指望这个变量根据你的点击不同li智能的改变自身么？
当然获取到的都只能是同一个了......
既然你说不是技术人员。我就不多解释了
修改如下：

'<li size="'+Size+'" onclick="javascript:document.getElementById(this.Size).value = this.innerHTML;">32D</li>'

每一个li都都这样写，该会吧？不用我完全写出来撒

[未知数]

晕 又忘了插入代码不能加色彩了！
'<li size="'+Size+'" onclick="javascript:document.getElementById(this.Size).value = this.innerHTML;">32D</li>'

[路伊阑珊]

你在$("#fblog-add1").click中是不是应该添加 else对I进行递减操作呢 要不你增加到5就不会发生变化了啊

[dmtlyc7517]

$('.selectl-inner-"'+Size+'"l').append(
'<dl class="frame-sel-filed pdt10">' +
'<dd class="frame-sel-dd-01">文胸尺码</dd>' +
'<dd class="select-box"><span>请选择...</span>' +
'<ul class="select-ul">' +
'<li class="bg-fff" onclick="javascript:document.getElementById("'+Size+'").value = this.innerHTML;">32A</li>' +'<li onclick="javascript:document.getElementById("'+Size+'").value = this.innerHTML;">32B</li>' +'<li class="bg-fff" onclick="javascript:document.getElementById("'+Size+'").value = this.innerHTML;">32C</li>' +

上面大意写错大小写
'<li size="'+Size+'" onclick="javascript:document.getElementById(this.size).value = this.innerHTML;">32D</li>'
这样才对,应该可以满足你所说的

[Go 旅城通票]

搞错，变为下面的，id是字符串，原来的代码导致
document.getElementById(\''+Size+'\')

这个方法对了，为什么要在LI里面多一个size="'+Size+'"来获取实际的Size的值就可以了呢？

[CainLai]

9L的方法也是对的！难道是我获取变量的格式写法没有对么！

[Go 旅城通票]

增加自定义属性存储当时的Size值，和我那个差不多

#9有点小bug就是非ie浏览器自定义属性size需要使用getAttribute来获取

请弄清楚逻辑，点击事件发生时，Size值已经是最后一次的值了，我先前都说了，你每次添加的条目里面使用的是同一个变量Size，难道你能指望这个变量自己智能改变自身么？当然都是同一个值

而我这段在写这个li时把当时的Size变量值记录在了size属性里面，点击时通过该属性获得的是生成该元素时Size的值而不是点击时Siae的值，清楚了么？
