网上看到的一款原生slider插件，觉得挺好用，https://github.com/mohammadFe...
引入插件
html
样式可以自己写一下
var mySlider2 = new slider({
// container element
container: "#container1",
// start/end values
start: 0,
end: 2000000,
// custom step
step: 1,
// initial value
value: 1500000,
ondrag: onDragChange2,
});
mySlider2.init();初始化插件
function onDragChange2(obj) {
$("#e").html(obj.values[0]);
}拖拽事件
obj为滑块对象，取值可通过obj.values[0]来取。
如果是移动端，初始化时需要添加isMobile属性；
if (!IsPC()) {
console.log('移动端')
mySlider2 = new slider({
// container element
container: "#container1",
start: 0,
end: 2000000,
// custom step
step: 1,
// initial value
isMobile: true,
value: 1500000,
ondrag: onDragChange2,
});
mySlider2.init();
mySlider3 = new slider({
// container element
container: "#container2",
// start/end values
start: 0,
end: 90,
isMobile: true,
// custom step
step: 1,
// initial value
value: 30,
ondrag: onDragChange3,
});
mySlider3.init();
} else {
console.log('不是移动端')
mySlider2 = new slider({
// container element
container: "#container1",
start: 0,
end: 2000000,
// custom step
step: 1,
// initial value
isMobile: false,
value: 1500000,
ondrag: onDragChange2,
});
mySlider2.init();
mySlider3 = new slider({
// container element
container: "#container2",
// start/end values
start: 0,
end: 90,
isMobile: false,
// custom step
step: 1,
// initial value
value: 30,
ondrag: onDragChange3,
});
mySlider3.init();
}动态初始化。
如果这个插件在移动端使用时报错，可以复制下面我改的代码：
