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)
