jQuery wrapAllInner()吗? -还是将wrapAll()相互应用? [英] Jquery wrapAllInner() ? -- Or wrapAll() applied interally?
问题描述
我正在尝试在<body>之后插入一个开头<div class="container">，在</body>之前插入一个结束</div>
I'm trying to insert an opening <div class="container"> after <body> and a closing </div> before </body>
我希望在元素的html()上有一个像wrapAll()这样的函数可以在内部应用.像wrapAllInner()这样的东西会很棒.
I'd like for there to be a function like wrapAll() that would apply internally, on the html() of an element. Something like wrapAllInner() would be great.
我尝试过:
1) $('body').html().wrapAll('<div class="container"></div>');
这根本不起作用. $("body").html().wrapAll不是函数.奇怪.
which didn't work at all. $("body").html().wrapAll is not a function. weird.
2) $('body').children().wrapAll('<div class="container"></div>');
由于某种原因导致js重复两次.它甚至导致我紧接其后放置的alert()重复两次. ut?
which for some reason caused the js to get repeated twice. It even caused an alert() I placed right after it to get repeated twice. whut?

推荐答案
只需 .wrapInner() 将单个<body>元素的内容包装在此处的方式如下:
Just a .wrapInner() to wrap the contents of the single <body> element works here, like this:
$('body').wrapInner('<div class="container"></div>');
.html() 不起作用的原因是
The reason .html() doesn't work is .html() without parameters gets the HTML inside the <body> element, a string, which doesn't have any jQuery functions.
