如何正确地将一种形式放置在另一种形式的前面？

标签： javascript jquery html css

所以我这里有一个示例，使用户可以A）登录或B）注册

它以主要显示形式显示登录表单，但我想对其进行切换，以便它首先显示“注册”，然后您可以切换到“登录”。 我已经尝试过切换Z索引位置，但这似乎并没有太大作用。 所以这让我想知道，实现此目标的正确方法是什么？

$('.message a').click(function(){
   $('form').animate({height: "toggle", opacity: "toggle"}, "slow");
});
@import url(https://fonts.googleapis.com/css?family=Roboto:300);

.login-page {
  width: 360px;
  padding: 8% 0 0;
  margin: auto;
}
.form {
  position: relative;
  z-index: 1;
  background: #FFFFFF;
  max-width: 360px;
  margin: 0 auto 100px;
  padding: 45px;
  text-align: center;
  box-shadow: 0 0 20px 0 rgba(0, 0, 0, 0.2), 0 5px 5px 0 rgba(0, 0, 0, 0.24);

这与z-index无关，这是基于一种形式最初被隐藏而另一种形式可见。

将.form .register-form { display: none; }替换为.form .login-form { display: none; } 

$('.message a').click(function(){
   $('form').animate({height: "toggle", opacity: "toggle"}, "slow");
});
@import url(https://fonts.googleapis.com/css?family=Roboto:300);

.login-page {
  width: 360px;
  padding: 8% 0 0;
  margin: auto;
}
.form {
  position: relative;
  z-index: 1;
  background: #FFFFFF;
  max-width: 360px;
  margin: 0 auto 100px;
  padding: 45px;
  text-align: center;
  box-shadow: 0 0 20px 0 rgba(0, 0, 0, 0.2), 0 5px 5px 0 rgba(0, 0, 0, 0.24);
}
.form input {
  font-family: "Roboto", sans-serif;
  outline: 0;
  background: #f2f2f2;
  width: 100%;
  border: 0;
  margin: 0 0 15px;

一种方法是将“登录表单” CSS设置为“ display：none”，然后在需要时进行切换      $（“。login-form”）。css（“ display”，“ block”） 例如，在设置时      $（“。register-form”）。css（“ display”，“ none”）

答案 2 :(得分：0)

只需从CSS中删除此行：

.form .register-form {
  display: none;
}

并添加以下内容：

.form .login-form {
  display: none;
}
