javascript - 无法让我的范围滑块正确显示值

问题描述

问题：当最终用户调整滑块位置时，我无法让我的范围滑块显示当前值。但是，当最终用户选择生成密码时，它会更新当前值。

有没有人对我如何让它按照我想要的方式运行有任何想法？

谢谢你。

// var rangeInput = document.getElementById("slider1").value;



document.getElementById('num').addEventListener("change", function() {
  let value = document.getElementById("slider1").value;
  document.getElementById("num").textContent = value;
  console.log(value);
}, false);


//generate a password

function passwordGenerator () {

    // how long is the password going to be?
    var passwordLength = document.getElementById('num').value;

   
  // characters options for PW

  const values = "ABCDEFGHIJKLabcdefghikk0123456789!@#$%";

  
  // defining password
  var password = "";


// creating a loop to choose password

for (var i = 1; i <= passwordLength; i++) {
    password = password + values.charAt(Math.floor(Math.random() * Math.floor(values.length -1)));
}
  
// adding the password to the content area


document.getElementById('num').textContent = (passwordLength);
document.getElementById('display').value = password;

}


//copy to clipboard
function selectText() {
  const input = document.getElementById('display');
  input.focus();
  input.select();
  document.execCommand('copy')
}
