js发布/订阅模式代码教程

直接上代码

js代码test.js

var xevent=(function(){
    function xevent(){
        this._events={};
    }
    xevent.prototype={
        emit:function(name,obj){
            if(name in this._events){
                for(var i=0;i
测试代码test.html


<script src="./test.js">
    </script><script>
        var event=new xevent();
        var test0=function(res){
            console.info('test0-----监听',res);
        };

        var test1=function(res){
            console.info('test1-----监听',res);
        };

        console.info('test0--------------------------start');
        event.on('test0',test0);

        event.emit('test0',{
            code:0,
            msg:'test0---0',
            data:null
        });

        console.info('test1-------------------移除监听测试');
        event.on('test1',test1);
        event.remove('test1');                              
        event.emit('test1',{
            code:1,
            msg:'test1---1',
            data:null
        });
    </script>[name].length;i++){>

测试结果

test0--------------------------start
test.html:15 test0-----监听 {code: 0, msg: "test0---0", data: null}
test.html:31 test1-------------------移除监听测试
