如何创建< style>用Javascript标记?
我正在寻找一种方法将< style>
标记插入带有JavaScript的HTML页面。
I'm looking for a way to insert a <style>
tag into an HTML page with JavaScript.
到目前为止我找到的最佳方式:
The best way I found so far:
var divNode = document.createElement("div");
divNode.innerHTML = "<br><style>h1 { background: red; }</style>";
document.body.appendChild(divNode);
这适用于Firefox,Opera和Internet Explorer,但不适用于Google Chrome。 IE前面的< br>
也有点难看。
This works in Firefox, Opera and Internet Explorer but not in Google Chrome. Also it's a bit ugly with the <br>
in front for IE.
有没有人知道一种方式创建< style>
标记
Does anyone know of a way to create a <style>
tag that

适用于Chrome?

这是我应该避免的非标准事项
This is a non-standard thing I should avoid
三种工作浏览器都很棒,无论如何都使用Chrome?
Three working browsers are great and who uses Chrome anyway?
尝试将样式
元素添加到 head
而不是正文
。
Try adding the style
element to the head
rather than the body
.
这是在IE(7-9),Firefox,Opera和Chrome中测试的:
This was tested in IE (7-9), Firefox, Opera and Chrome:
var css = 'h1 { background: red; }',
head = document.head || document.getElementsByTagName('head')[0],
style = document.createElement('style');
style.type = 'text/css';
if (style.styleSheet){
// This is required for IE8 and below.
style.styleSheet.cssText = css;
} else {
style.appendChild(document.createTextNode(css));
}
head.appendChild(style);
