「綁定」 [重點新聞]與[點擊進入]

Question

我有一個電子郵件的形式提交，我希望把它的OnEnter submittable（不只是點擊）

這裏是我的按鈕

submitBtn.addEventListener(MouseEvent.CLICK, submitForm); 
function submitForm(e:Event) { 
///do stuff 
} 

代碼

下面是文本字段代碼

emailAddress.addEventListener(KeyboardEvent.KEY_DOWN,handler); 
function handler(event:KeyboardEvent){ 
    if(event.charCode == 13){ 
     //submitForm() < this doesn't work (Expected 1) 
    } 
} 

感謝

Answer 1

emailAddress.addEventListener(KeyboardEvent.KEY_DOWN,handler); 

function handler(event:KeyboardEvent) 
{ 
if(event.charCode == 13) 
{ 
    submitForm(null) 
} 
} 

Answer 2

submitBtn.addEventListener(MouseEvent.CLICK, submitForm); 
emailAddress.addEventListener(KeyboardEvent.KEY_DOWN, handler); 

function submitForm(e:MouseEvent=null) 
{ 
    ///do stuff 
}; 

function handler(event:KeyboardEvent) 
{ 
    if(event.charCode == 13) submitForm(); 
};

函數submitForm（）;預計要傳遞1個參數，是一個事件類型的變量：
功能submitForm（E：事件）

因此需要設置的情況下的參數不傳遞默認值：
功能submitForm （e：MouseEvent = null）
