Question

我试着让mousedown函数在ios上工作但是似乎无法修复issuse。我知道问题在于下面的代码，任何帮助都会很棒！

 bindInteractions: function(){
        // bind interactions used during live play
        this.playfield.on('mousedown','touchstart', _.throttle(_.bind(function(event){
            this.fireGun();
            var weaponSpread = this.player.getWeapon().getSpread();
            if(weaponSpread <= 0) {
              console.error("Zero spread weapons can do no damage. Recommended minimum size: 25");
            }
            var playfieldOffset = $(event.delegateTarget).offset();
            var location = {
                top: event.pageY - playfieldOffset.top,
                left: event.pageX - playfieldOffset.left
            };
            $.each(this.liveDucks, function(i,duck){
               duck.shotsFired(location, weaponSpread);
            });

        },this), this.player.getWeapon().getReloadTime()));
        this.showLevelInfo();
    },
    unbindInteractions: function(){
        // unbind interactions that should not be available during transitions and other non live play states
        this.playfield.off('mousedown','touchstart');
        $.each(this.liveDucks, function(i, duck) {
            duck.unbindEvents();
        });

根据JQuery documentation关于.on()

.on（events [，selector] [，data]，handler）

活动

类型：字符串一个或多个以空格分隔的事件类型和   可选的命名空间，例如＆＃34; click＆＃34;或＆＃34; keydown.myPlugin＆＃34;。

它说One or more space-separated event types。

所以也许你的mousedown和touchstart应该在同一个字符串参数中：

this.playfield.on('mousedown touchstart', _.throttle(_.bind(function(event){

}

Mousedown没有在Iphone上工作？
