Javascript获取和设置浏览器的可用性 [英] Javascript get and set availability in browsers

问题描述

哪些浏览器不支持对象原型的get和set方法？我相信这是ES5的一个功能，我知道它在Chrome中工作，但我想知道是否可以安全地用于ajax应用程序。这里有一个例子：

  var foo = function（）{}; 
 foo.prototype = {
 get name（）{
 return this._name; 
}，
 set name（n）{
 this._name = n || 酒吧; 
} 
};

请参阅属性初始化程序中的 Getter 和 / code>行。

根据表格：

• Firefox 4


• Safari 5


• Chrome 7-11

其他浏览器（包括IE9）没有给予是或否，因此也许未经测试。我确定IE9支持它。

Which browsers do not support the get and set methods for object prototypes? I believe this is a feature of ES5, an I know it works in Chrome, but I am wondering if it is safe to use for ajax apps. Here's an example:

var foo = function () {};
foo.prototype = {
    get name () {
        return this._name;
    },
    set name (n) {
        this._name = n || "bar";
    }
};

解决方案

Here's a compatibility table for you.

http://kangax.github.com/es5-compat-table/

See the Getter in property initializer and Setter in property initializer rows.

According to the table:

• Firefox 4
• Safari 5
• Chrome 7-11

Other browsers (including IE9) are not given a Yes or No, so perhaps they're untested. I'm pretty sure IE9 supports it.
