var arr=[1,2,3,4,5,6,7,8,9,10];var arr2=[];$(function(){$('.btn').on('click',function(){var push=arr[Math.floor(Math.random()*arr.length)];arrJoin(push);})});function arrJoin(joinNub){for(var i=0;i<arr2.length;i++){if(joinNub==arr[i]){joinNub=arr[Math.floor(Math.random()*arr.length)];arrJoin(joinNub);}}arr2.push(joinNub);}//每次點擊都添加一個新的數字到arr2，不知道哪里沒做好，求大神指點
arr2數組添加內容時不能與之前的內容重復
