var tabletd_gg=document.getElementById('gg_blank').innerHTML; var count = 0; var res_gg = tabletd_gg.replace(/~/g, function(x){ var symbol = count++ == 1 ? '~<br/>' : x; return symbol;}); document.getElementById('gg_blank').innerHTML=res_gg;效果是這樣的轉換為什么用getElementsByClassName()就失效了？
為什么下面這個代碼不能把id換成class
