消息:对象不支持此属性或方法

Question

我在IE 8上打开我的网站时遇到以下错误,

Message: Object doesn't support this property or method
Line: 25
Char: 13
Code: 0
URI: mycode.js

mycode.js文件代码

var LstCompanies = Object.keys(msg);
if (LstCompanies.length > 0) {

有任何想法吗

IE中不支持Object.keys.这是更安全的实现,与所有浏览器兼容..

Object.keys = Object.keys || function(o) { 
    var keysArray = []; 
    for(var name in o) { 
        if (o.hasOwnProperty(name)) 
          keysArray.push(name); 
    } 
    return keysArray; 
};
