的Javascript電話號碼自動轉換不工作

我有一些JavaScript代碼像下面的Javascript電話號碼自動轉換不工作

function mask(eventVal,val){ 
    var len = val.value.length; 
    var key = whichKey(eventVal); 
    if(key>47 && key<58) 
    { 
     if(len==0)val.value=val.value+'(' 
     else if(len==4)val.value=val.value+') ' 
     else if(len==9)val.value=val.value+'-' 
     else val.value=val.value; 
    } 
    else{ 
     val.value = val.value.replace(/[^0-9-]/,'') 
     val.value = val.value.replace('--','-') 
    } 
} 

function whichKey(eventVal) { 
    var code; 
    if (!eventVal) var eventVal = window.event; 
    if (eventVal.keyCode) code = eventVal.keyCode; 
    else if (eventVal.which) code = eventVal.which; 
    return code; 
}

HTML

<input type="text" name="PhoneNumber" id="PhoneNumber" value="" onkeydown="mask(event,this)"/>

它工作正常，當我輸入電話號碼，像1234567890自動轉換成（ 123）456-7890當我試圖刪除像從結尾刪除0值，然後格式化完全毀了。像123）456-789，甚至當我點擊任何其他地方時，它都會毀了。任何人都可以幫我解決它嗎？

的問題是，退格鍵和其他非數字字符將沿着您的'else'路徑進行，替換爲刪除之前添加的括號。除此之外，您可能想使用'onkeyup'而不是'onkeydown'，這樣您就可以使用_after_值來處理輸入的任何字符。無論如何，以下是供玩家玩的演示：http://jsfiddle.net/weSvU/ – nnnnnn

P.S.還要注意的是，因爲您在'if'測試中使用_key_代碼而不是_character_代碼，所以對於通過數字鍵盤輸入的字符以及（在我的國家/地區的鍵盤上）1和！具有相同的鍵碼，2和@具有相同的鍵碼，等等。我建議你處理'onblur'，這樣你就不必處理試圖在字符串中間編輯的用戶等等。當他們離開現場時只需重新格式化整個字符串... – nnnnnn

您的代碼不起作用 – Soumya

謝謝。它真的有效。 – Soumya

如果您編輯以前輸入的值，則不起作用，例如，如果刪除括號之間的數字。至少，它在Chrome中無效：http://jsfiddle.net/pZKPS/ – nnnnnn

你可以試試這個代碼替換您的最後一個數字

<script type="text/javascript"> 
function fnc() 
{ 

    str=document.getElementById("atext").value; 
    x=(str.match(pattern)); 
    if(x!="") 
    {str=str.replace(/[0-9]$/g,'')} 
    alert(str); 
} 

</script> 
<body> 
    <input type="text" id="atext"> 
    <input type="button" onClick="fnc()"> 
</body>
