无效的分配左侧与三元if [英] Invalid assignment left-hand side with ternary if

问题描述

我想创建一个这样的样式表：

I want to create an stylesheet like this:

var sheet = document.createElement('style'); sheet.type = 'text/css';
sheet.innerHTML = data.style;

但似乎 IE需要自己的语法。为了简化此答案的代码，我试过了

But it seems that IE needs its own syntax. To simplify this answer's code, I have tried

var sheet = document.createElement('style'); sheet.type = 'text/css';
(sheet.styleSheet ? sheet.styleSheet.cssText : sheet.innerHTML) = data.style;

但抛出 ReferenceError：左侧无效分配。

然后，我必须使用...

Then, must I use...

var sheet = document.createElement('style'); sheet.type = 'text/css';
if(sheet.styleSheet) sheet.styleSheet.cssText = data.style;
else sheet.innerHTML = data.style;

...还是有更简单的选择？

... or is there a simpler alternative?

推荐答案

您可以随时执行：

sheet.styleSheet ? sheet.styleSheet.cssText = data.style 
                 : sheet.appendChild(document.createTextNode(data.style));
