Javascript函數無法識別onclick

我有一個名爲formApprove（）的JavaScript函數，並在按鈕上的html onclick中調用該函數。出於某種原因，javascript函數未被識別，因爲firebug告訴我forApprove不是函數。下面是在頭代碼：Javascript函數無法識別onclick

<script type="text/javascript"> 
function formApprove() { 
var TheTextBox = document.getElementById("formApprove"); 
TheTextBox.value = 'true'; 
alert("hellp"); 
return true; 
} 
</script>

下面是在身體的代碼：

<input type="submit" name="approve" value="Approve Membership" onclick="formApprove()" />

任何幫助，在此將不勝感激。

全碼：

<head> 
<script type="text/javascript"> 
function nextPrevious(txtElement, btnElement) { 
    switch(btnElement.name) { 
     case 'increase': 
      var numrows = document.getElementById("numOfRows"); 
      if (txtElement.value < Number(numrows.value)) { 
       txtElement.value++; 
      } else { 
        alert('You are alread at the end of the members'); 
        return false; 
      } 
      break; 
     case 'decrease': 

      if(txtElement.value > 1) { 
       txtElement.value--; 
      } else { 
        alert('You are alread at the begining of the members'); 
        return false; 
      } 
      break; 

     case 'goto': 
      alert(txtElement.value); 
      break; 
     default: 
    } 
    return true; 
} 

function approve() { 
    var TheTextBox = document.getElementById("formApprove"); 
    TheTextBox.value = 'true'; 
    alert("hellp"); 
    return true; 
} 

function formChange() { 
    var TheTextBox = document.getElementById("formSubmit"); 
    TheTextBox.value = 'true'; 
    return true; 
} 


function deleteRecord() { 
    var answer = confirm ("Are you sure you want to delete record?"); 
    if (answer) { 
     var TheTextBox = document.getElementById("formDelete"); 
     TheTextBox.value = 'true'; 
     return true; 
    } else {return false;} 

}

您的腳本標籤位於頭標籤之間嗎？ – Adil 2013-04-08 17:43:42

在此之前，螢火蟲會提及任何其他錯誤嗎？也許在頁面上出現某種語法錯誤。 – 2013-04-08 17:43:45

@Rikonator這就是所需要的準確** ** **。這個函數需要聲明纔可以調用 – Ian 2013-04-08 17:44:22

你可能有一個名稱衝突與功能和元素的名稱。

重新命名該函數或重命名文本框。
