這是你的抓取class? JS代碼“var oDiv=document.getElementsByClassName('div');”
這是你body里的代碼??
<div class="div1"></div>
<div class="div1"></div>
<div class="div1"></div>
<div class="div1"></div>
<div class="div1"></div>
? 應該如下 ‘’var oDiv=document.getElementsByClassName('div1');‘’
? 或者如下? ” var oDiv=document.getElementsByTagName('div');”
