內嵌td標記的javascript onlick

Question

我想在其中提交<form>和<table>。如何使用默認操作提交<form>？使用<select>標籤，我可以使用onchange javascript函數提交表單。我認爲onclick="this.form.submit"裏面的<td>標籤會解決，但螢火蟲表示有錯誤：TypeError: this.form is undefined

有什麼不對？你指的是在的onclick功能

<div class="report"> 
    <form method="post" name="status_students"> 
    <table width="100%" border="0" cellspacing="0" cellpadding="0"> 
     <tr> 
     <td class="tdreport">Active</td> 
     <td class="tdreport">Unstable</td> 
     <td class="tdreport">Inactive</td> 
     </tr> 
     <tr> 
     <td class="active" name="students_actives" value="actives" onclick="this.form.submit()"> 
      <?php 
      if ($this->siteCenterSelected == "All") { 
      echo count($this->usersStatus['verde']); 
      } else { 
      echo count($this->usersStatusSiteCenter['verde']); 
      } 
      ?> 
     </td> 
     <td class="unstable"><?php 
      if ($this->siteCenterSelected == "All") { 
      echo count($this->usersStatus['amarelo']); 
      } else { 
      echo count($this->usersStatusSiteCenter['amarelo']); 
      } 
      ?> 
     </td> 
     <td class="inactive"><?php 
      if ($this->siteCenterSelected == "All") { 
      echo count($this->usersStatus['vermelho']); 
      } else { 
      echo count($this->usersStatusSiteCenter['vermelho']); 
      } 
      ?> 
     </td> 
     </tr> 
    </table> 
    </form> 
</div>

this對象是點擊td，而不是整個文件。你可能想用這個來代替：

onclick="document.forms[0].submit()" 

但的確，你最好用它的ID來引用表單。
