javascript - 将多个实例的JS转换为jQuery click函数

Question

我有一个在Javascript中运行一次的函数（通过调用id）。我尝试将功能转换为jQuery，以允许该功能适用​​于pwd的每个实例。

我如何让jQuery代码像JS代码一样工作，但要在pwd的每个实例上运行？

$(".pass").on("click", ".typcn-eye", function() {
  var pwd = $(this).closest(".pwd");

  function togglePass() {
    $(this).toggleClass("active");

    pwd.type == "password" ? (pwd.type = "text") : (pwd.type = "password");
  }
});

var pwd = document.getElementById('pwd');
var eye = document.getElementById('eye');

eye.addEventListener('click', togglePass);

function togglePass() {

  eye.classList.toggle('active');

  (pwd.type == 'password') ? pwd.type = 'text': pwd.type = 'password';
}

.box {
  display: flex;
  flex-direction: column;
  align-items: start;
}

.pass {
  display: flex;
  align-items: center;
  border: 1px solid;
}

.box input[type="text"],
.box input[type="password"] {
  display: block;
  margin: 20px auto;
  background: #ececec;
  border: 0;
  border-radius: 5px;
  padding: 14px 10px;
  width: 220px;
  outline: none;
  color: #565f79;
}

.typcn {
  color: #3b476b;
  font-size: 22px;
  cursor: pointer;
}

.typcn.active {
  color: #7f60eb;
}

在click事件的jQuery版本上，您具有功能togglePass（），但从未触发过它。由于您使用的是其他版本。

// For triggering you function
$(".pass").on("click", ".typcn-eye", togglePass);

// Function outside your click event
function togglePass() {
    // Toggle active class on every click
    $(this).toggleClass("active");
    // Get the type of the prev element 
    let type = $(this).prev().attr("type"),
        changeTo = type === "password" ? "text" : "password";

    // Change type attr of that element
    $(this).prev().attr("type", changeTo);
}

.box {
    display: flex;
    flex-direction: column;
    align-items: start;
}

.pass {
    display: flex;
    align-items: center;
    border: 1px solid;
}

.box input[type="text"],
.box input[type="password"] {
    display: block;
    margin: 20px auto;
    background: #ececec;
    border: 0;
    border-radius: 5px;
    padding: 14px 10px;
    width: 220px;
    outline: none;
    color: #565f79;
}

.typcn {
    color: #3b476b;
    font-size: 22px;
    cursor: pointer;
}

.typcn.active {
    color: #7f60eb;
}
