本篇文章给大家带来的内容是关于小程序中多滑块的实现代码 ,有一定的参考价值,有需要的朋友可以参考一下,希望对你有所帮助。
最近在用原生的代码开发小程序,需要用到多滑块的slider,但是官方的api只支持单滑块,所以就在原来的基础上草草的写了一个。有什么不足的地方还请大家多多指教,想封装成组件的也可自行封装,我这就不讲了。;
话不多说,上代码:
html:
view >css
.sliderHCon { height: 250rpx; width: 100%; margin: auto; display: flex; justify-content: center; align-items: center; flex-direction: column; .MoneyValue { font-size: 30rpx; text-align: center; color: #999; margin-top: 15rpx; .showMoney text { margin-right: 30rpx; .twoSlider { width: 100%; height:100px; display: flex; flex-direction: row; justify-content: center; align-items: center; position: relative; .slider-left,.slider-right{position: absolute;left:0;right:0;} .slider-bg{position: absolute;top:50%;margin-top:-1px;left:0;width:100%;height:2px;background: blue;z-index: 9;}js
