Javascript 获取HTML表中用于模式jQuery的行ID；PHP

所以这次我有一个HTML表，当我点击位于标记中的锚时，它会打开一个模式，在那里我们可以更改用户密码

      <header>
        <h3>Alterar Password</h3>
      </header>

      <div class="modal-body">

        <form action="" method="POST" id="changepw" name="changepw">            
            <label>Nova Password:</label><br/>
            <input class="textbox" type="password" name="newpassword" id="newpassword" /> <br/>

            <input class="btnSubmit" type="submit" name="changepwSub" id="changepwSub" form="changepw" value="Alterar Password" />          
        </form>         
      </div>

      <footer>
        <a href="#" class="js-modal-close"><input class="btnSubmit" type="button" value="Fechar" style="max-width:100px;" /></a>
      </footer>

      <?php

       //The PHP Code to Update it will be here.
        $query = "UPDATE auth SET password=xxx WHERE ID="

       ?>  
    </div>

但要更新用户表中的密码，我需要获取ID。我的问题是，如何在模式中获取行ID/用户ID

      <header>
        <h3>Alterar Password</h3>
      </header>

      <div class="modal-body">

        <form action="" method="POST" id="changepw" name="changepw">            
            <label>Nova Password:</label><br/>
            <input class="textbox" type="password" name="newpassword" id="newpassword" /> <br/>

            <input class="btnSubmit" type="submit" name="changepwSub" id="changepwSub" form="changepw" value="Alterar Password" />          
        </form>         
      </div>

      <footer>
        <a href="#" class="js-modal-close"><input class="btnSubmit" type="button" value="Fechar" style="max-width:100px;" /></a>
      </footer>

      <?php

       //The PHP Code to Update it will be here.
        $query = "UPDATE auth SET password=xxx WHERE ID="

       ?>  
    </div>

“我的表格”是通过以下内容创建的：

for ($i = 0; $i < $size; $i++) {
print ("
<tr>
<td>".$Users[$i][0]."</td>
<td>".$Users[$i][1]."</td>
<td>*****</td>
<td><a data-modal-id='delete' href='#' >Change PW</a></td>
</tr>
<tr>");
}

      <header>
        <h3>Alterar Password</h3>
      </header>

      <div class="modal-body">

        <form action="" method="POST" id="changepw" name="changepw">            
            <label>Nova Password:</label><br/>
            <input class="textbox" type="password" name="newpassword" id="newpassword" /> <br/>

            <input class="btnSubmit" type="submit" name="changepwSub" id="changepwSub" form="changepw" value="Alterar Password" />          
        </form>         
      </div>

      <footer>
        <a href="#" class="js-modal-close"><input class="btnSubmit" type="button" value="Fechar" style="max-width:100px;" /></a>
      </footer>

      <?php

       //The PHP Code to Update it will be here.
        $query = "UPDATE auth SET password=xxx WHERE ID="

       ?>  
    </div>

（$i=0；$i<$size；$i++）的

{
打印（“
“$Users[$i][0]”
“$Users[$i][1]”
*****
");
}

因此，当我单击锚定时，模态打开，我可以设法使模态工作。我需要的是以某种方式获取ID来构建SQL查询以更新密码

      <header>
        <h3>Alterar Password</h3>
      </header>

      <div class="modal-body">

        <form action="" method="POST" id="changepw" name="changepw">            
            <label>Nova Password:</label><br/>
            <input class="textbox" type="password" name="newpassword" id="newpassword" /> <br/>

            <input class="btnSubmit" type="submit" name="changepwSub" id="changepwSub" form="changepw" value="Alterar Password" />          
        </form>         
      </div>

      <footer>
        <a href="#" class="js-modal-close"><input class="btnSubmit" type="button" value="Fechar" style="max-width:100px;" /></a>
      </footer>

      <?php

       //The PHP Code to Update it will be here.
        $query = "UPDATE auth SET password=xxx WHERE ID="

       ?>  
    </div>

模式：

      <header>
        <h3>Alterar Password</h3>
      </header>

      <div class="modal-body">

        <form action="" method="POST" id="changepw" name="changepw">            
            <label>Nova Password:</label><br/>
            <input class="textbox" type="password" name="newpassword" id="newpassword" /> <br/>

            <input class="btnSubmit" type="submit" name="changepwSub" id="changepwSub" form="changepw" value="Alterar Password" />          
        </form>         
      </div>

      <footer>
        <a href="#" class="js-modal-close"><input class="btnSubmit" type="button" value="Fechar" style="max-width:100px;" /></a>
      </footer>

      <?php

       //The PHP Code to Update it will be here.
        $query = "UPDATE auth SET password=xxx WHERE ID="

       ?>  
    </div>

交替密码
Nova密码：

您只需要3个步骤：

      <header>
        <h3>Alterar Password</h3>
      </header>

      <div class="modal-body">

        <form action="" method="POST" id="changepw" name="changepw">            
            <label>Nova Password:</label><br/>
            <input class="textbox" type="password" name="newpassword" id="newpassword" /> <br/>

            <input class="btnSubmit" type="submit" name="changepwSub" id="changepwSub" form="changepw" value="Alterar Password" />          
        </form>         
      </div>

      <footer>
        <a href="#" class="js-modal-close"><input class="btnSubmit" type="button" value="Fechar" style="max-width:100px;" /></a>
      </footer>

      <?php

       //The PHP Code to Update it will be here.
        $query = "UPDATE auth SET password=xxx WHERE ID="

       ?>  
    </div>

按照注释中的建议，将用户ID嵌入到链接到单击的锚点/行/单元格/任何对象的数据集中。例如，

修改生成模式的脚本以读取该数据并添加隐藏的表单字段。例如，

“

”

在PHP脚本中，只需检索该额外字段以填充SQL查询

---

我希望这是一种管理局，你有适当的凭据和安全。您可能需要在服务器端检查用户是否具有修改具有给定ID的用户记录的凭据，因为任何人都可以传递假ID并修改其他人的记录。

这里的data modal userId=user ID

以及如何在PHP变量中获取该ID？我假设它在$users中？问题不是将ID传递给data moda userId。问题是在模式打开后，当我单击Update Password时，如何在我编写查询的部分获得该ID？提前谢谢。

      <header>
        <h3>Alterar Password</h3>
      </header>

      <div class="modal-body">

        <form action="" method="POST" id="changepw" name="changepw">            
            <label>Nova Password:</label><br/>
            <input class="textbox" type="password" name="newpassword" id="newpassword" /> <br/>

            <input class="btnSubmit" type="submit" name="changepwSub" id="changepwSub" form="changepw" value="Alterar Password" />
