使用 bootstrap 5 密码字段中的眼睛不会出现

Question

当使用 Bootstrap v5 和 FontAwesome v5 时，我无法让眼球出现在表格的右侧。相反，它会将密码字段拉到比用户名字段更靠右的位置，并且不会显示眼睛。

<div class="input-group mb-3">
   <span class="input-group-text"><i class="fas fa-lock"></i></span>
   <input class="form-control" id="username" name="username" placeholder="Username" value="">
</div>

<div class="input-group mb-3">
   <span class="input-group-text"><i class="fas fa-lock"></i></span>
   <input class="form-control" id="password" name="password" placeholder="Password" value="">
   <span class="input-group-text"><i class="far fa-eye-slash" id="togglePassword"></i></span>
</div>

Javascript

const togglePassword = document.querySelector("#togglePassword");
const password = document.querySelector("#password");

togglePassword.addEventListener("click", function () {
   
// toggle the type attribute
const type = password.getAttribute("type") === "password" ? "text" : "password";
password.setAttribute("type", type);

// toggle the eye icon
this.classList.toggle('fa-eye');
});

Answer 1

尝试将 z-index:2; 添加到您的图标。为了防止在输入字段获得焦点时隐藏眼睛图标，您需要添加以下 css 代码：-

<style>
#password:focus ~ .far-fa-eye{
margin-left: -30px !important; 
cursor: pointer !important;
z-index: 5 !important;
}
</style>

此外，请与我们分享您的用户名字段的视觉效果或代码，以便我们更好地理解您的意思。

PS：我希望尽可能避免内联 css。在调试大型 css 代码时，内联 css 可能会很麻烦。

Answer 2

当图标与输入重叠时，它位于输入标签下方。要解决此问题，您需要将 <i> 标签设置为更高的 z-index 值。尝试使用 z-index: 100 使其即使在单击输入时也显示在顶部。

<div class="input-group mb-3">
   <span class="input-group-text"><i class="fas fa-lock"></i></span>
   <input class="form-control" id="password" name="password" placeholder="Password" value="">
   <i class="far fa-eye" id="togglePassword" 
   style="cursor: pointer; margin-left: -30px; z-index: 100;"></i>
</div>

编辑：如果您希望密码字段和用户名字段的宽度相同，您可以尝试将图标包裹在 input-group-text 内并删除样式 margin-left: -30px; z-index: 100; 因为 input-group-text 与输入字段重叠。

<div class="input-group mb-3">
  <span class="input-group-text"><i class="fas fa-lock"></i></span>
  <input class="form-control" id="username" name="username" placeholder="Username" value="">
</div>

<div class="input-group mb-3">
  <span class="input-group-text"><i class="fas fa-lock"></i></span>
  <input class="form-control" id="password" name="password" placeholder="Password" value="">
  <span class="input-group-text">
    <i class="far fa-eye" id="togglePassword" 
   style="cursor: pointer"></i>
   </span>
</div>

编辑 2： 在您的 JavaScript 代码中，您使用 this.classList.toggle('fa-eye') 隐藏了眼睛图标。此函数在togglePassword元素的classList中有classfa-eye时去掉，没有时加上上面的class

我假设您希望在用户当前处于文本格式时显示可能是 eye-slash icon 的隐藏密码图标。所以你可以添加

this.classList.toggle('fa-eye-slash');

如下

const togglePassword = document.querySelector("#togglePassword");
const password = document.querySelector("#password");

togglePassword.addEventListener("click", function () {
   
  // toggle the type attribute
  const type = password.getAttribute("type") === "password" ? "text" : "password";
  password.setAttribute("type", type);
  // toggle the eye icon
  this.classList.toggle('fa-eye');
  this.classList.toggle('fa-eye-slash');
});

Answer 3

实施 Jquery 3.6.0 与 Bootstrap 5

HTML

<div class="mb-3">
    <label class="form-label">Password</label>
    <div class="input-group mb-3">
        <input class="form-control password" id="password" class="block mt-1 w-full" type="password" name="password" required />
        <span class="input-group-text">
            <i class="far fa-eye-slash" id="togglePassword"
            style="cursor: pointer"></i>
        </span>
    </div>
</div>

JS

$(".togglePassword").click(function (e) {
e.preventDefault();
var type = $(this).parent().parent().find(".password").attr("type");
console.log(type);
if(type == "password"){
    $(this).removeClass("fa-eye-slash");
    $(this).addClass("fa-eye");
    $(this).parent().parent().find(".password").attr("type","text");
}else if(type == "text"){
    $(this).removeClass("fa-eye");
    $(this).addClass("fa-eye-slash");
    $(this).parent().parent().find(".password").attr("type","password");
}});

Answer 4

使用羽毛图标的示例 Jquery 3.3 Bootstrap 5

  feather.replace({ 'aria-hidden': 'true' });

$(".togglePassword").click(function (e) {
      e.preventDefault();
      var type = $(this).parent().parent().find(".password").attr("type");
      console.log(type);
      if(type == "password"){
          $("svg.feather.feather-eye").replaceWith(feather.icons["eye-off"].toSvg());
          $(this).parent().parent().find(".password").attr("type","text");
      }else if(type == "text"){
          $("svg.feather.feather-eye-off").replaceWith(feather.icons["eye"].toSvg());
          $(this).parent().parent().find(".password").attr("type","password");
      }
  });
