我有6個(gè)滑塊，每個(gè)滑塊的相應(yīng)值都是0-100。我希望能夠在每個(gè)滑塊的右側(cè)顯示每個(gè)滑塊百分比(相對(duì)于總滑塊總數(shù))，但我不確定如何做到這一點(diǎn)。顯示HTML5滑塊值旁邊的百分比

我能搶滑塊值上面顯示，以及滑塊值和值，如JavaScript變量的總和，但我不能......

1)更新的百分比(我想我可能需要編寫一個(gè)單獨(dú)的函數(shù)來(lái)完成此操作，然后在顯示滑塊值后立即調(diào)用它)或

2)顯示百分比值一個(gè)有效的整數(shù))在滑塊值的后面。

任何人都可以告訴我如何做到這一點(diǎn)？從技術(shù)角度來(lái)看，這不應(yīng)該很困難，但我在這方面經(jīng)驗(yàn)不足。我也沒有使用jquery(正如你所知道的)......謝謝！
