};我的一个朋友给了我上面的一个js文件,要我实现一下功能,鼠标移到上面的1时,下面列表对应显示1,移到上面2对应显示2,3也一样。这个js网页上怎么用啊,前辈请指点,万分感谢!!!
这个也是示例
onmouseover
onmouseout列表切换用到的是:
listObj.style.display = "none";
listObj.style.display = "";别的知识点也没啥了。
$(function () {
$("div:gt(0)").hide(); });
function showonmouseover(obj) {
var id = $(obj).attr("id");
for (var i = 1; i <= 5; i++) {
if(i==id) {
$("#div" + i).show();
}
else
$("#div" + i).hide();
}
}
