tab學(xué)習(xí)中，發(fā)現(xiàn)點(diǎn)擊后，前面的內(nèi)容沒(méi)隱藏，代碼也一樣啊為什么~糾結(jié)死了
JS代碼
window.onload=function(){
var?title=document.getElementsByTagName("p");
????????var?content=document.getElementsByTagName("ul");
????????
??????//?將所有點(diǎn)擊的標(biāo)題和要顯示隱藏的列表取出來(lái)
????????for(var?i=0;i<title.length;i++){
????????????title[i].name=i;
????????????title[i].onclick=function(){
????????????????for(var?j=0;content<i.length;j++){
????????????????????content[j].style.display="none";
????????????????}
????????????????content[this.name].style.display="block";
????????????}
????????}
?????//?遍歷所有要點(diǎn)擊的標(biāo)題且給它們添加索引及綁定事件
?????//?獲取點(diǎn)擊的標(biāo)題上的索引屬性，根據(jù)該索引找到對(duì)應(yīng)的列表
?????//?判斷該列表，如果是顯示的則將其隱藏，如果是隱藏的則將其顯示出來(lái)
}全部代碼
