Question

我有以下功能：

format : function(element,p){
 //function body
 if(event.type == 'focus'){
   //execute this condition only on focus event 
 }
}

正在焦点事件和页面加载上调用。 element是输入元素的值，p是可选的参数，我想只在重点放在input元素上执行if。如果我只是应用event.type =='focus'，它适用于IE和chrome，但对于firefox，它表示事件未定义。

有没有人有解决方法？提前谢谢。

var myObj = {
    format: function (event) {
        // passing in the event object should give you everything you need:
        // event.type (the event's type)
        // event.target (the element which the event was fired on)
        // event.which (in the case of keyboard events, this is the key that was pressed)
        // see mdn dox @ https://developer.mozilla.org/en-US/docs/Web/API/Event
        if (event.type === 'focus') {
            // execute focus code
        }
    }
};

firefox中的event.type undefined
