如何将 .roundSlider() 应用于 Array 的所有元素？

Question

一个元素没问题，但是这里抛出错误“el.roundSlider不是函数”，Jquery在主js文件之前连接，与Jquery .each一样

const scArr = Array.from($('.slider'));

scArr.forEach(el => el.roundSlider({
    radius: 80,
    circleShape: "half-left",
    sliderType: "min-range",
    showTooltip: false,
    value: 150,
    width: 10,
    min: 0,
    max: 200
 }));

Answer 1

直接使用jquery类选择器就可以了

$('.slider').roundSlider({
  radius: 80,
  circleShape: "half-left",
  sliderType: "min-range",
  showTooltip: false,
  value: 150,
  width: 10,
  min: 0,
  max: 200
});

<div class="slider"></div>
<div class="slider"></div>
<div class="slider"></div>

Answer 2

$(el) 似乎可以解决问题：

const scArr = Array.from($('.slider'));

scArr.forEach(el => $(el).roundSlider({
    radius: 80,
    circleShape: "half-left",
    sliderType: "min-range",
    showTooltip: false,
    value: 150,
    width: 10,
    min: 0,
    max: 200
 }));

jquery array 中的每个元素都不是 jquery 对象，我相信它实际上是一个节点元素。在浏览器中试试这个：$('p')[0] instanceof Element
