js 擷取html5的data屬性實現方法，html5data
我以前一直以為只能用jquery的data()來擷取
哈哈 是我太弱了
<!DOCTYPE html><html><head> <title>dataset</title> <meta charset="utf-8"></head><body> <div id='div' data-index='demo'> </div></body><script type="text/javascript">var a = document.getElementById('div');console.log(a)console.log(a.dataset.index)//demo</script></html>
直接用dataset就可以擷取到DOM元素的data屬性
好吧，還可以 用js的擷取屬性的方法getAttribute()
a.getAttribute('data-index')==>"demo"
以上這篇js 擷取html5的data屬性實現方法就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支援幫客之家。
