English 中文(简体)
通过jquery 加入动态元件
原标题:accing dynamic element through jquery

我想实现这个目标

$("div1 input").attr( id );

div1 通过php 循环动态生成( 所以我喜欢 div1, div2, div3 等 )

在我的 jquery 函数中, i 有 $ (# confer.). val (); , 它动态地将卡路里数从 1 到 3 动态地包含,

所以这就是我正在做的 $ ("# div"+$ ("# aconfer"). val () + "input".attr (id)

上面的代码应该给我输入属性 ID,

由于某些原因或可能是由于我无法理解的语法问题所致, < enger> 查看并指出我的错误 。 感谢提前感谢

您错过了 input 之前的空间, 请尝试一下 :

$("#div" + $("#counter").val() + " input").attr( id )
问题回答

You need to use your code, AFTER you are generated your divs. So you need to put <script> after loop generation or on document ready event.
Try following:

$(function()
{
        var $el = $("#div"+ $("#counter").val() +" input");
        //or you can use alert($el.length) to see if $el created.
        if ($el.length)
        {
           var id =  $el.attr( id );
        }

});
