UC知道javascript 获取id
来源：百度知道 编辑：UC知道 时间：2024/06/23 05:38:33
<div id="img" style="position:absolute; width:100px; height:80px; left:10px; top:5; ">
<img width="100" height="80" id="id1" src="images/_KF[HIA5TB~@SC7[~2U$[KR.jpg" />
</div>
<div id="img1" style="position:absolute; width:100px; height:80px; left:9px; top:89px; ">
<img width="100" height="80" id="id2" src="images/1.jpg" onmouseover="" /></div>
<div id="img2" style="position:absolute; width:100px; height:80px; left:9px; top:171px; ">
<img width="100" height="80" id="id3" src="images/2.jpg" onmouseover="" /> </div>
当把鼠标放到图片上时怎么循环获得不同图片的ID？？用这document.getElementById("img2");只能单独获得，图片数量多就太麻烦

恩。楼上正解。。。
var imgs=document.getElementsByTag(img);
for(var i=0 ;i<imgs.length;i++){
alert(imgs[i].id);
}
给你写了个例子 看看吧！！ 鼠标放上 移开 点击时的各种变化，绝对适合你的！！
