javascript - 如何更改范围 slider 以显示金钱？

标签 javascript jquery html css

我在 codepen 上找到了这个 slider 。

如何让它显示最低 500 欧元和最高 6000 欧元，但保留红色背景？

我已经尝试了一切，例如。

<input id = "range" type = "range" class = "range-slider" min = "500" max = "6000" step = "100">

但是范围 slider 拉伸(stretch)到 6000%，而且我不擅长 JS。

const rangeSlider = document.querySelector('.range-slider');
const rangeValueBar = document.querySelector('#range-value-bar');
const rangeValue = document.querySelector('#range-value');



let isDown = false;

function dragHandler() {
  isDown = !isDown;
  if (!isDown) {
    rangeValue.style.setProperty('opacity', '1');
  } else {
    rangeValue.style.setProperty('opacity', '1');
  }
}

function dragOn(e) {
  if (!isDown) return;
  rangeValueHandler();
}

function rangeValueHandler() {
  rangeValueBar.style.setProperty('width', `${rangeSlider.value}%`);
  rangeValue.innerHTML = `${rangeSlider.value}€`;
}

rangeValueHandler();
rangeSlider.addEventListener('mousedown', dragHandler);
rangeSlider.addEventListener('mousemove', dragOn);
rangeSlider.addEventListener('mouseup', dragHandler);
rangeSlider.addEventListener('click', rangeValueHandler);

最佳答案

我相信这就是您想要的，只需对范围 slider 表单元素使用 min 和 max 属性，我要做的就是删除 rangeValueHandler 函数中的宽度样式。

我必须计算宽度百分比:

((输入 - 最小值) *100)/(最大值 - 最小值)}%

const rangeSlider = document.querySelector('.range-slider');
const rangeValueBar = document.querySelector('#range-value-bar');
const rangeValue = document.querySelector('#range-value');



let isDown = false;

function dragHandler() {
  isDown = !isDown;
  if (!isDown) {
    rangeValue.style.setProperty('opacity', '1');
  } else {
    rangeValue.style.setProperty('opacity', '1');
  }
}

function dragOn(e) {
  if (!isDown) return;
  rangeValueHandler();
}

function rangeValueHandler() {
  percentage = `${((rangeSlider.value - 500) * 100) / (6000 - 500)}%`; 
  rangeValueBar.style.setProperty('width', percentage);
  rangeValue.innerHTML = `${rangeSlider.value}€`;
}

rangeValueHandler();
rangeSlider.addEventListener('mousedown', dragHandler);
rangeSlider.addEventListener('mousemove', dragOn);
rangeSlider.addEventListener('mouseup', dragHandler);
rangeSlider.addEventListener('click', rangeValueHandler);
body {
  padding: 100px;
