javascript - 使用html中的链接调用JS函数

Question

我想将我的 div 设置为，如果我调用 sign up，sign in 隐藏，反之亦然。我写了这段 JS 代码，但我无法调用这些函数来应用上述场景。碰巧的是，这两个 divs 同时出现在窗口上，这是不可取的。我应该怎么做，以便每当我按下登录链接时，注册 div 隐藏，类似地，当我点击新建时帐户，登录 div 隐藏。

$(document).ready(function() {
  $("#signIn").click(function() {
    $(".signUpHide").hide(600);
    $(".signInShow").show(600);
    $(this).hide();
    $("#signUp").show();
  });
});

$(document).ready(function() {
  $("#signUp").click(function() {
    $(".signInHide").hide(600);
    $(".signUpShow").show(600);
    $(this).hide();
    $("#signIn").show();
  });
});

body {
  height: 100vh;
  width: 208vh;
}

.leftPanel {
  background-color: #660033;
  width: 70%;
  height: 100%;
  float: left;
  position: absolute;
}

.rightPanel {
  background-color: white;
  width: 30%;
  height: 100%;
  float: right;
}

.signInClass {}

.signInHide {}

Answer 1

首先，代码可以重构为单个document.ready，您可以使用toggle() 显示/隐藏 元素。其次，id 的用法需要固定为 id="SignIn" 而不是 href="#SignIn"

$(document).ready(function() {
  $("#signIn,#signUp").click(function() {
    $(".signIn, .signUp").toggle();
  });
});

height: 100vh;
width: 208vh;

}
.leftPanel {
  background-color: #660033;
  width: 70%;
  height: 100%;
  float: left;
  position: absolute;
}
.rightPanel {
  background-color: white;
  width: 30%;
  height: 100%;
  float: right;
}
.signInClass {}
.signInHide {}
