這次添加的是自己新瞭解到的隨筆，要讓css active偽類生效，只需要給這個元素的touchstart/touchend綁定一個空的匿名方法即可成功。。。下面簡單舉個栗子
複製代碼<!DOCTYPE html><html><head><style>p { color: yellow;}p:active { color: red;}</style></head><body> <p>測試Active文本</p></body><script> var p=document.getElementsByTagName(‘p‘); for(var i=0;i<p.length;i++){ p[i].addEventListener(‘touchstart‘,function(){},false); };</script></html>複製代碼 用JS代碼擷取這個元素，然後通過addEventListener添加一個touchstart的方法即可。 這樣當點擊到文本時，就能發現顏色從黃變紅，active偽類生效啦！希望對你們有所協助iOS Web開發啟用css
