如果它是一个数字或包含数字,jQuery中的this.id将不会获取元素id

Question

我有一堆自动生成的div,它们的id有一个数字.每当我使用this.id来获取id时,它都不会输出任何内容.但是,当Id仅为文本时,它会正确输出ID.我怎么能解决这个问题？一切都有帮助.谢谢

编辑:

$(".draggable").draggable();
$("*", document.body).click(function (e) {   
                var offset = $(this).offset();
                e.stopPropagation();
                $("#result").text(this.tagName + "  ID:" + this.id + " Coord:" + offset.left + " " + offset.top);
                $.post("http://localhost/framework/test.php", "id=" + this.id + "&x=" + offset.left + "&y=" + offset.top);
            });

这是违法的代码.然而,它将获得div的id,而不应用"draggable"类.

   <div id="container">

       <div id="1" class="draggable" style="top:55px; left:55px; border: 2px solid black; display: inline-table; position: relative; background-color: grey; max-width: 500px;">

请注意,仅限数字的ID无效.有关详细信息,请参阅此帖子.

简短而甜蜜的是:

ID和NAME令牌必须以字母([A-Za-z])开头,后面可以跟任意数量的字母,数字([0-9]),连字符(" - "),下划线("_") ,冒号(":")和句号(".").
