Object doesn't support this property or method EmberJs IE 8 issue
提问by SharpCoder
I am getting following error on my IE 8 page (The page is running fine in other browsers).
我的 IE 8 页面出现以下错误（该页面在其他浏览器中运行良好）。
User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; .NET4.0E; InfoPath.3)

Message: Object doesn't support this property or method
Line: 70532
Char: 5
Code: 0
When I checked the line 70532 in the file mentioned, i saw this code:
当我检查提到的文件中的第 70532 行时，我看到了以下代码：
if (!Object.create && !Object.create(null).hasOwnProperty) {
throw new Error("This browser does not support Object.create(null), please polyfil with es5-sham: http://git.io/yBU2rg");
}
What does it meant by Please polyfil with es5-sham:
Please polyfil with es5-sham是什么意思：
Please polyfil with es5-sham: http://git.io/yBU2rg
How can I fix this error.
我该如何解决这个错误。

Object.createis not supported in IE8, therefore your framework is asking you to "polyfil" it, which means you need to implement something which should have been supported natively, but for some reason, this particular environment doesn't know about it.
Object.createIE8 不支持，因此你的框架要求你“polyfil”它，这意味着你需要实现一些本应支持的东西，但由于某种原因，这个特定的环境不知道它。
It means, if you want to use Object.createyou have to implement it yourself. Fortunatelly, you don't have to do much, the url ( https://github.com/es-shims/es5-shim/blob/master/es5-sham.js) points to a file which contains the neccesary polyfills.
Just run that script before your framework script does.
这意味着，如果你想使用它，Object.create你必须自己实现它。幸运的是，你不必做太多，url ( https://github.com/es-shims/es5-shim/blob/master/es5-sham.js) 指向一个包含必要 polyfills 的文件。只需在您的框架脚本运行之前运行该脚本。
update:
This line seems broken to me: !Object.create && !Object.create(null).hasOwnProperty.
If Object.createis not there, calling it like Object.create(null)should throw an error, but I think it should be something like 'undefined is not a function'.
更新：
这条线似乎打破对我说：!Object.create && !Object.create(null).hasOwnProperty。
如果Object.create不存在，则调用它Object.create(null)应该会引发错误，但我认为它应该类似于“未定义不是函数”。

I found another polyfil which is working in my scenario. I found the answer at this link.
我找到了另一个在我的场景中工作的 polyfil。我在这个链接上找到了答案。
I am adding code form that link
我正在添加链接的代码表单
if (!Object.create) {
Object.create = function(proto, props) {
if (typeof props !== "undefined") {
throw "The multiple-argument version of Object.create is not provided by this browser and cannot be shimmed.";
}
function ctor() { }
ctor.prototype = proto;
return new ctor();
};
}
adding this code seems to be doing trick for me. Only change I made is, I commented the code where exception is thrown as it is resulting in another error.
添加此代码似乎对我有用。我所做的唯一更改是，我注释了抛出异常的代码，因为它会导致另一个错误。
