一个解决中午吃什么去哪吃的程序
这下不用每天都纠结吃什么了！
<html>
<head>
<script type="text/javascript" src="jquery-1.12.1.js"></script>
<style type="text/css">
#bigDiv div{
height:50px;
width:50px;
float:left;
background-color:red;
margin-left:5px;
visibility: hidden;
}
#bigDiv p{
margin-left: 10px;
}
</style>
</head>
<body>
<div id = bigDiv>
<div><p>吃面</p></div>
<div><p>吃饭</p></div>
<div><p>兰州</p></div>
<div><p>随便</p></div>
<div><p>炒饭</p></div>
<div><p>一期</p></div>
<div><p>二期</p></div>
<div><p>全家</p></div>
<div><p>西北</p></div>
<div><p>谢谢</p></div>
</div>
<br/><br/><br/><br/>
<input type="button" id="startBtn" value="开 始" onclick="startRun()">
<input type="button" id="confirmBtn" value="确 定" onclick="stopRun()">
<script language="javascript">
var allDiv = $("#bigDiv").find("div");
var t;
function startRun(){
var index = 11;
$(allDiv).each(function(i){
if($(this).css("visibility")!="hidden"){
index = i;
}
});
if(index == 11){
index = parseInt(9*Math.random());
}
$(allDiv).eq(index).css("visibility","visible");
setTimeout(function(){stepRun(index);},50);
}
function stepRun(index){
if($(allDiv).eq(index).css("visibility")!="hidden")
{
$(allDiv).eq(index).css("visibility","hidden");
if(index==9){
$(allDiv).eq(0).css("visibility","visible");
t = setTimeout(function(){stepRun(0)},50);
}else{
$(allDiv).eq(index+1).css("visibility","visible");
t = setTimeout(function(){stepRun(++index)},50);
}
}
}
function stopRun()
{
clearTimeout(t);
}
</script>
</body>
</html>
例二：单按钮实现
