解除绑定所有事件处理程序，做一些事情，然后再绑定jquery

Question

我试图存储一个元素的所有事件处理程序，然后解开它们，然后做一些事情，然后再次绑定，但通常处理程序的变量被修改为当我取消绑定处理空对象

var events = $._data(this.$element.get(0), 'events'); 
    console.log(events); //here the variable events contains an object with the handlers 
    this.$element.unbind(); 
    console.log(events); //here the variable events contains an empty object 

    //function to bind again the handlers 
    $.each(events, function() { 
    // iterate registered handler of original 
    $.each(this, function() { 
     $('#target').bind(this.type, this.handler); 
    }); 
    });

您可以使用extend深模式在events数据复制：

var events = $._data(this.$element.get(0), 'events'), 
    eventsCopy = $.extend(true, {}, events); 
this.$element.unbind(); 
$.each(eventsCopy, function() { 
    $.each(this, function() { 
     $('#target').bind(this.type, this.handler); 
    }); 
});
