限制双拇指滑块上的最大值和最小值

Question

我有两个拇指范围滑块来设置最大值和最小值，现在我意识到可以越过拇指-最大值可以超过最小值，最小值可以超过最大值。

我想限制min不超过max和max不超过min

经过一些研究，我没有看到任何有用的JS。有什么我可以使用的选项吗?

const twoRangeSlider = (() => {
const rangeCheck = (rangeInputs, rangeMinOutput, rangeMaxOutput) => {
const rangeMin = rangeInputs[0].min ? rangeInputs[0].min : 0;
const rangeMax = rangeInputs[0].max ? rangeInputs[0].max : 100;
let rangeMinValue = parseFloat(rangeInputs[1].value);
let rangeMaxValue = parseFloat(rangeInputs[0].value);
rangeMinValue = Math.min(Math.max(rangeMinValue, rangeMin), rangeMaxValue);

const rangeMinPercentage = Number(
((rangeMinValue - rangeMin) * 100) / (rangeMax - rangeMin));
const rangeMaxPercentage = Number(
((rangeMaxValue - rangeMin) * 100) / (rangeMax - rangeMin));

rangeInputs[0].style.background = `linear-gradient(to right, #000 ${rangeMaxPercentage}%, #c4c8ca ${rangeMaxPercentage}%)`;
rangeInputs[1].style.background = `linear-gradient(to right,#c4c8ca ${rangeMinPercentage}%, transparent ${rangeMinPercentage}%)`;

};
const bindComponent = (item) => {
const rangeInputs = item.querySelectorAll('.js-two-range-slider-input');
const rangeMinOutput = item.querySelector('.js-two-range-slider-min-value');
const rangeMaxOutput = item.querySelector('.js-two-range-slider-max-value');
item.addEventListener("input", () => {
rangeCheck(rangeInputs, rangeMinOutput, rangeMaxOutput);
});
rangeCheck(rangeInputs, rangeMinOutput, rangeMaxOutput);
};
const init = () => {
const rootEl = document.getElementsByClassName("js-two-range-slider");
[...rootEl].forEach((item) => bindComponent(item));
};
return {
init
};
})();
twoRangeSlider.init();

我把你的例子缩短了一点，以显示我在评论中的意思。

const twoRangeSlider = (() => {
const bindComponent = (item) => {
const rangeInputs = item.querySelectorAll('.js-two-range-slider-input');
item.addEventListener("input", ({ target }) => {
const [ right, left ] = rangeInputs;
if (target == right) {
left.value = Math.min(+right.value -1, +left.value);
} else {
right.value = Math.max(+left.value +1, +right.value);
}
});
};
const init = () => {
const rootEl = document.getElementsByClassName("js-two-range-slider");
[...rootEl].forEach((item) => bindComponent(item));
};
return {
init
};
})();
twoRangeSlider.init();

.two-range-slider {
position: relative;
