今晚吃啥呢？——随机摇饭店前后端代码-91天空科技生活快乐

最近每天晚上都在纠结到底去哪儿吃呢，百般折磨下终于决定写个页面替自己做决定！

HTML部分：

<h1 style="color:#40AA53">吃啥呢！</h1>

<div id="board">

 <span id="ResultNum">0</span>

<div id="Button">
 <input type='button' id="btn" value='开始' onclick='beginRndNum(this)'/>
</div>
<div id="footer">

JS部分:

其实就是random一个数组，和随机摇数字的原理一样，只不过把数字改成数组的下标就可以了。

var g_Interval = 1;
var g_PersonCount = 25;
var g_Timer;
var running = false;
   /**
    * what2eat
    * coder: xiaohudie
    * 2017-11-03
    */
function beginRndNum(trigger){
 if(running){
 running = false;
 clearTimeout(g_Timer); 
 $(trigger).val("开始");
 $('#ResultNum').css('color','#00cc75');
 }
 else{
 running = true;
 $('#ResultNum').css('color','black');
 $(trigger).val("停止");
 beginTimer();
 }
}

function updateRndNum(){
 var arr=[
 "云端",
 "粤菜",
 "嘉和一品",
 "杜小月",
 "西少爷",
 "心泰心厨",
 "热啊",
 "跃界",
 "渝是乎",
 "萨莉亚",
 "宏状元", 
 "外婆家",
 "鳗鱼饭",
 "面香"
 ]
 var num = Math.floor(Math.random()*g_PersonCount+1);
 var num2 = arr[num];//把random出来的数字变成数组下标
 $('#ResultNum').html(num2);
}

function beginTimer(){
 g_Timer = setTimeout(beat, g_Interval);
}

function beat() {
 g_Timer = setTimeout(beat, g_Interval);
 updateRndNum();
}
