こんにちは、みんな?ボタンが押されるまで div コンテンツを非表示にするにはどうすればよいですか? テーブルの「新しい教師を追加」ボタンが押されるまで、このdivが表示されないようにしたいです。これは、ボタンが押されるまで非表示にしたい div コンテンツです
<div id="myform">
<p align="center">
<strong>
Add information for new teacher here
</strong></p>
<form action="<?php echo $editFormAction; ?>" method="post" name="form1" id="form1">
<table align="center" id="forms">
<tr valign="baseline">
<td nowrap="nowrap" align="right">First name:</td>
<td><input type="text" name="first_name" value="" size="32" /></td>
</tr>
<tr valign="baseline">
<td nowrap="nowrap" align="right">Last name:</td>
<td><input type="text" name="last_name" value="" size="32" /></td>
</tr>
<tr valign="baseline">
<td nowrap="nowrap" align="right">Subjects:</td>
<td><input type="text" name="subjects" value="" size="32" /></td>
</tr>
<tr valign="baseline">
<td nowrap="nowrap" align="right">Phonenumber:</td>
<td><input type="text" name="phonenumber" value="" size="32" /></td>

<tr valign="baseline">

</tr>
<tr valign="baseline">

<tr valign="baseline">
<td nowrap="nowrap" align="right"> </td>
<td><input type="submit" value="Insert record" id="hideit"/></td>
</tr>
</table>
<input type="hidden" name="MM_insert" value="form1" />
</form>
<p> </p>
</div>
