将任意HTML插入DocumentFragment [英] Inserting arbitrary HTML into a DocumentFragment
问题描述
我知道将 innerHTML
添加到文档片段最近已经讨论过,希望能够纳入DOM标准。但是,在此期间您应该使用的解决方法是什么?
I know that adding innerHTML
to document fragments has been recently discussed, and will hopefully see inclusion in the DOM Standard. But, what is the workaround you're supposed to use in the meantime?
即,
var html = '<div>x</div><span>y</span>';
var frag = document.createDocumentFragment();
我想要 div
和 span
在 frag
内,有一个简单的单行。
I want both the div
and the span
inside of frag
, with an easy one-liner.
没有循环的奖励积分。允许jQuery,但我已经尝试过 $(html).appendTo(frag)
;之后 frag
仍然是空的。
Bonus points for no loops. jQuery is allowed, but I've already tried $(html).appendTo(frag)
; frag
is still empty afterward.
推荐答案
这是一种方式a href =http://caniuse.com/template>现代浏览器没有循环:
Here is a way in modern browsers without looping:
var temp = document.createElement('template');
temp.innerHTML = '<div>x</div><span>y</span>';
var frag = temp.content;
或作为可重复使用的
function fragmentFromString(strHTML) {
var temp = document.createElement('template');
temp.innerHTML = strHTML;
return temp.content;
}
更新:
我找到了一种更简单的方式来使用Pete的主要想法,它将IE11添加到组合中:
UPDATE: I found a simpler way to use Pete's main idea, which adds IE11 to the mix:
function fragmentFromString(strHTML) {
return document.createRange().createContextualFragment(strHTML);
}
保险范围优于< template>
方法并在IE11,Ch,FF中测试好。
The coverage is better than the <template>
method and tested ok in IE11, Ch, FF.
