定位div并获取外部js文件的工作onload

时间：2015-03-03 08:48:55

标签： javascript html css

我有一个JavaScript和CSS，可以在小提琴中使用，但不是在我使用外面的小提琴时。 fiddle

  1. 当我将其插入下面的html时，它不起作用。我相信我错过了一些代码？
  2. 当我没有从jsfiddle查看时，计数div不在正确的位置。如何相对于搜索input？
    3. 定位它
  3. 生成表需要一分钟，是因为我的代码写得不好？ *我确实有800个* 8柱

    4. 提前谢谢。

2 个答案:

答案 0 :(得分：1)

你必须使s_box相对，以便计数根据它变为绝对

.s_box {
 position: relative;
}

答案 1 :(得分：1)

由于使用了这个JavaScript $("<div>", {class: "tablewrapper"})，会出现错误。它应该像所有地方$("<div>", {"class": "tablewrapper"})一样。

这表明，在从JavaScript准备HTML之前，请使用文档就绪事件或将JavaScript放在html正文元素的末尾。
