javascript与php注册自己的“事件”

var a = function(){
this.eve
this.func
this.on = function(eve,func){
    this.eve = eve
    this.func = func
}
this.emit = function(eve){
    if(this.eve == eve){
        var func = this.func
        func()
    }
}
}
var aa = new a()
aa.on('click',function(){
console.log('im click')
})
aa.emit('click')

b. 输出：

im click

<?php
class a{
public $eve;
public $func;
public function on($eve,$func){
    $this->eve = $eve;
    $this->func = $func;
}
public function emit($eve){
    if($this.eve == $eve){
        $func = $this->func;
        $func();
    }
}
}
$a = new a();
$a->on('click',function(){
echo "im click";
});
$a->emit('click');

b. 输出：
