通过DOM搜索动态插入的标签 [英] Search a dynamically inserted tag through DOM

问题描述

Hii全部，

是否可以通过DOM搜索动态插入的标签?
例如，在我的html页面中，如果我创建一个"video"标签(使用document.createElement("video"))，是否可以通过DOM检查该标签是否包含在页面中?如果可能的话，我该怎么做?

谢谢.....

Hii All,

Is it possible to search for a dynamically inserted tag through DOM?.
For example, in my html page if I create a "video" tag(using document.createElement("video")), is it possible to check through DOM whether that tag is included in the page or not? If possible how will I do that?

Thanks.....

是的！你可以.

一旦它们成为文档页面的一部分，就可以在DOM中访问它们.

=====
更新:
创建标签后，您需要将该标签添加到任何现有的先前标签中.完成后，您应该可以遍历它.

看这里:
使用Javascript动态添加和删除HTML元素 [ ^ ]
动态DOM内容 [

Yes! you can.

Once they are the part of the document page, they are accessible in DOM.

=====
UPDATE:
Once you create a tag, you need to add that tag to any existing previous tags. Once done, you should be able to traverse it out.

Look here:
Add and Remove HTML elements dynamically with Javascript[^]
Dynamic DOM content[^]

如Sandeep Mewara所说，

document.createElement 这将创建一个仅在DOM中尚未插入的对象实例(元素)，
要添加/插入它，您需要在所需元素父示例中使用 appendChild :

0)您有一个 Div ，其ID为="VidzArea"
1)您可以使用 document.getElementById
获得该DIV的引用
2)现在 DIV (VidzArea)是您想要的父母
3)，最后将其添加到 document.createElement

as Sandeep Mewara says,

document.createElement this create a just an object instance (element) not inserted yet in DOM,
for to add/insert it, you need to use appendChild in desired element parent example :

0) you have a Div with id = "VidzArea"
1) you get reference of this DIV by using document.getElementById

2) now DIV (VidzArea) is your desired parent
3) and finally you add it your Video element created by document.createElement
