[英]How do you enclose unknown HTML in a div with plain Javascript?
I have an HTML page that has varying types of content. 我有一个HTML页面,其中包含各种类型的内容。 I would like to make a javascript function that when run encloses anything inside the
<body>
tag with a <div id="content-container">
. 我想制作一个JavaScript函数,在运行时将
<body>
标记内的所有内容括入<div id="content-container">
。 Then I want to be able to add a <div id="verifying"></div>
that new <div>
. 然后,我希望能够添加一个
<div id="verifying"></div>
新的<div>
。 I think I know how to do this with jQuery, but I need to do it with plain Javascript. 我想我知道如何使用jQuery,但是我需要使用普通的Javascript来实现。
Any idea as to how this would be done? 关于如何做到这一点的任何想法吗?
This is how I might do it. 这就是我可能会做的。
var body = document.body;
var contentContainer = document.createElement('div');
contentContainer.id = 'content-container';
var node;
while (node = body.firstChild) {
contentContainer.appendChild(node);
}
body.appendChild(contentContainer);
var verifying = document.createElement('div');
verifying.id = 'verifying';
contentContainer.appendChild(verifying);
I haven't tested, but I imagine that you can take the innerHTML of document and set it to be itself along with whatever wrapper string (or div) you want. 我还没有测试,但是我想您可以获取文档的innerHTML并将其设置为所需的任何包装字符串(或div)本身。
Something along the lines of: 类似于以下内容:
body = methodToLocateBodyInTheDom();
body.innerHTML = "<div id='content-container'>" + body.innerHTML + "</div>"
There are probably better ways, but I think something of that nature sure work. 可能有更好的方法,但是我认为这种性质的方法一定可以工作。
