Question

我的PHP页面中有一个删除按钮，用于删除记录。但是，当我删除该按钮时，我会使用以下确认框：

<form action="log.php" method="post" onsubmit="return confirm('Are you sure?');">

当他们确认必须填写密码时，我可以这样做吗？

所以我的意思是这样的

<form action="log.php" method="post" onsubmit="return confirm('password :');">

然后他们必须填写密码

提前致谢。

Answer 1

嗨，你需要这样的东西，根据你的要求修改

var result = $( ".form-horizontal" ).filter( function(){

   return $( this ).find( '.form-control' ).size() == 0;

} );

Answer 2

尝试使用input type="password"，required属性`;禁用提交，直到设置密码

＆＃13;

document.forms["form"].querySelector("input[type=button]").onclick = function(e) {
  e.preventDefault();
  this.nextElementSibling.disabled = false;
  this.nextElementSibling.nextElementSibling.disabled = false;
}

＆＃13;

<form name="form">
  <input type="button" value="Are you sure?" />
  <input type="password" minlength="3" maxlength="7" required disabled />
  <input type="submit" disabled />
</form>

＆＃13;

Answer 3

document.forms["form"].querySelector("input[type=button]").onclick = function(e) {
  e.preventDefault();
  this.nextElementSibling.disabled = false;
  this.nextElementSibling.nextElementSibling.disabled = false;
}

<form name="form">
  <input type="button" value="Are you sure?" />
  <input type="password" minlength="3" maxlength="7" required disabled />
  <input type="submit" disabled />
</form>

确认框中的密码Javascript
