JS 数组去重！！！

		var arr = [1,2,3,1,1,1,3,5,3,6,2];

		var newArr=[];

		for(var i = 0; i < arr.length-1; i++){

		    var onOff = false;

		    for(var j = i-1;j >= 0;j--){

		        if(arr[i]==arr[j]) {

		        	onOff = true;

		        	break;

		        }

		    }

		    if(!onOff) newArr[newArr.length]=arr[i]

		}

		alert(newArr)
