嗨，大家好？在按下按钮之前如何隐藏 div 内容？谁能帮帮我。我希望这个 div 在按下表格中的“添加新教师”按钮之前不显示。这是我希望隐藏的 div 内容，直到按下按钮

     <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>
    <tr valign="baseline">
      <td nowrap="nowrap" align="right">Email:</td>
      <td><input type="text" name="email" value="" size="32" /></td>
    </tr>
    <tr valign="baseline">
      <td nowrap="nowrap" align="right">Username:</td>
      <td><input type="text" name="username" value="" size="32" /></td>
    </tr>
    <tr valign="baseline">
      <td nowrap="nowrap" align="right">Password:</td>
      <td><input type="text" name="password" value="" size="32" /></td>
    </tr>
    <tr valign="baseline">
      <td nowrap="nowrap" align="right">&nbsp;</td>
      <td><input type="submit" value="Insert record" id="hideit"/></td>
    </tr>
  </table>
  <input type="hidden" name="MM_insert" value="form1" />
</form>
<p>&nbsp;</p>
</div>

这是我的表格，其中包含“添加新老师”按钮

    <p align="center">

试试看，

$(function(){
   $('button#showit').on('click',function(){  
      $('#myform').show();
   });
});

最初div应该hidden像_

<div id="myform" style="display:none">
.....

将display:none样式添加到您的 div，然后$("#div-id").show();单击按钮调用。

<div id="myform" style="display:none">
  // contents here
</div>

在您的新教师表单上添加内联样式以隐藏表单

<div id="myform" style="display:none">

或者在你的 jQuery 中简单地添加

$(document).ready(function(){
    // hide form on page load
    $('#myform').hide();

    // when button is pressed
    $('button').on('click',function(){  
      $('#myform').show();
   });
});

在您的代码中进行以下更改：

<div id="myform" style="display:none;">

在要隐藏的 div 中添加样式。

并将您的按钮代码修改为：

<button id="showit">+Add new Teacher</button>

并添加这个 jQuery：

$(document).ready(function(){
   $("#showit").click(function(){
       $("#myform").css("display","block");
   });
});

$(function(){
    $('.button_name').click(function(){  
      $('#myform').show();
    });
 });





<button class="button_name">


    <div id="myform" style="display:none">

或使用 java 脚本

function new_disp(){
   document.getElementById('myform').style.display='block';
 }




<button onclick='new_disp();'>


    <div id="myform" style="display:none">
