Javascript 数组观察

Question

observe(arr,callback) 结合 riot.js

但是当我尝试观察我的数组时，我得到 Array.observe is not a function.

Array.observe(this.nodes, function (changes) 
{
    //do some stuff
    tag.update();
});

错误

Uncaught TypeError: Array.observe is not a function(…)(anonymous function)
@components/breadcrumb-navigation.tag.js:3(anonymous function) 
@ riot+compiler.js:1604(anonymous function) 
@ riot+compiler.js:1719each

Answer 1

Array.observe 方法已过时并已删除。
建议使用 Proxy。
