我的HTML

<td colspan="4"> 
    <div id="myTableData" style="display:none;"> 
     <table> 
      <tr> 
       <td width="175">NAME</td> 
       <td width="245">&nbsp;Gender</td> 
       <td width="245">Date of Birth</td> 
      </tr> 
     </table> 
    </div> 
</td> 
<td colspan="2"> 
    <div class="addkidbg" onClick="addrow()" />ADDKID</div> 
</td> 

當我在addrow按鈕，點擊它告訴我三排，但我需要用戶點擊只有一次，如果用戶刪除行列名應該消失，但如果我點擊兩次addrow按鈕，然後單擊刪除按鈕.......否認其顯示列名稱。我想，如果用戶刪除該行的整體部分應b遠去又不能點擊超過一次

Answer 1

function addrow() { 
    rowcount++; 
    console.log("nis" + rowcount); 
    if (rowcount >= 2) { 
     rowcount = 0; 
     return false; 
    } 
} 

<div class="addkidbg" onClick="return addrow();" />ADDKID</div> 

試試這個代碼更。你的函數返回一個值，所以在onclick事件中首先寫回報
