javascript - 关闭后窗口不会再次打开 - 解除绑定(bind)

Question

我有一个按钮可以打开弹出窗口。再次点击自身，弹出窗口应该关闭(这个有效)。但关闭后无法重新打开窗口。我该如何解决这个解除绑定(bind)问题？

//loading Popup
//0 means disabled; 1 means enabled;
var popupStatus = 0;
function loadPopup ($elem) {
    //loads popup only if it is disabled
    if(popupStatus==0){  
        $elem.fadeIn(300, function(){
        //Closing popup by clicking the button
            $("#popup-button").bind("click", function(){
                    disablePopup();
            });
        });
        popupStatus = 1;  
    }
}

//disable popup
function disablePopup(){
        //disables popup only if it is enabled  
        if(popupStatus==1){  
            $(".popup-background").fadeOut("slow");  
                    $("#popup-wrapper").fadeOut("slow");

            $("#popup-button").unbind("click", function(){
                    disablePopup();
            });
             popupStatus = 0;  
        }
    }

我认为没有解绑的必要，尝试这样的事情:

$('#popup-button').click(function(){
    $('#popup-window').fadeToggle();
});
