用layui帮我写一个修改密码

好的，以下是使用layui实现修改密码的代码：

HTML代码：

<div class="layui-form-item">
  <label class="layui-form-label">原密码</label>
  <div class="layui-input-inline">
    <input type="password" name="oldPwd" required lay-verify="required" placeholder="请输入原密码" autocomplete="off" class="layui-input">
  </div>
</div>
<div class="layui-form-item">
  <label class="layui-form-label">新密码</label>
  <div class="layui-input-inline">
    <input type="password" name="newPwd" required lay-verify="required" placeholder="请输入新密码" autocomplete="off" class="layui-input">
  </div>
</div>
<div class="layui-form-item">
  <label class="layui-form-label">确认密码</label>
  <div class="layui-input-inline">
    <input type="password" name="confirmPwd" required lay-verify="required" placeholder="请再次输入新密码" autocomplete="off" class="layui-input">
  </div>
</div>
<div class="layui-form-item">
  <div class="layui-input-block">
    <button class="layui-btn" lay-submit lay-filter="changePwd">修改密码</button>
  </div>
</div>

JavaScript代码：

layui.use(['form', 'layer'], function(){
  var form = layui.form;
  var layer = layui.layer;
  
  // 监听修改密码表单提交
  form.on('submit(changePwd)', function(data){
    // 获取表单数据
    var oldPwd = data.field.oldPwd;
    var newPwd = data.field.newPwd;
    var confirmPwd = data.field.confirmPwd;
    
    // 判断新密码和确认密码是否一致
    if (newPwd !== confirmPwd) {
      layer.msg('新密码和确认密码不一致');
      return false;
    }
    
    // 发送修改密码请求
    $.ajax({
      url: 'changePwd.php',
      type: 'POST',
      data: {
        oldPwd: oldPwd,
        newPwd: newPwd
      },
      success: function(res){
        if (res.code === 0) {
          layer.msg('修改密码成功');
          // 清空表单数据
          form.val('changePwdForm', {
            oldPwd: '',
            newPwd: '',
            confirmPwd: ''
          });
        } else {
          layer.msg(res.msg);
        }
      },
      error: function(){
        layer.msg('网络错误，请稍后再试');
      }
    });
    
    return false;
  });
});

注意：以上代码中的changePwd.php是修改密码的后端接口，需要根据实际情况进行修改。
