javascript - 幸运之轮 - 最终选择与指针不匹配

标签 javascript jquery html

我想制作“旋转轮”类型的游戏,因为用户可以选择三种可能的结果,然后,在他们旋转轮子之后,如果出现所选择的三个中的任何一个,那么他/她就是赢家.

在下面的演示中,您可以看到,微调器停止后,结果不是正确的值。微调器本身停止后,它会继续并更改值——在最后一个之前,它始终是灯泡。 (请全屏查看我指的是什么。)

我该如何解决这个问题?

//set default degree (360*5)
var degree = 1800;
//number of clicks = 0
var clicks = 0;

$(document).ready(function(){
	
	/*WHEEL SPIN FUNCTION*/
	$('#spin').click(function(){
		
		//add 1 every click
		clicks ++;
		
		/*multiply the degree by number of clicks
	  generate random number between 1 - 360, 
    then add to the new degree*/
		var newDegree = degree*clicks;
		var extraDegree = Math.floor(Math.random() * (360 - 1 + 1)) + 1;
		totalDegree = newDegree+extraDegree;
		
		/*let's make the spin btn to tilt every
		time the edge of the section hits 
		the indicator*/
		$('#wheel .sec').each(function(){
			var t = $(this);
			var noY = 0;
			
			var c = 0;
			var n = 700;	
			var interval = setInterval(function () {
				c++;				
				if (c === n) { 
					clearInterval(interval);				
				}	
					
				var aoY = t.offset().top;
				$("#txt").html(t.html());
				console.log(aoY);
				
				/*23.7 is the minumum offset number that 
				each section can get, in a 30 angle degree.
				So, if the offset reaches 23.7, then we know
				that it has a 30 degree angle and therefore, 
				exactly aligned with the spin btn*/
				if(aoY < 23.89){
					console.log('<<<<<<<<');
					$('#spin').addClass('spin');
					setTimeout(function () { 
						$('#spin').removeClass('spin');
					}, 100);	
				}
			}, 10);
			
			$('#inner-wheel').css({
				'transform' : 'rotate(' + totalDegree + 'deg)'			
			});
		 
			noY = t.offset().top;
			
		});
	});
	
	
	
});//DOCUMENT READY

最佳答案

The setInterval() method will continue calling the function until clearInterval() is called, or the window is closed.

setInterval 返回 clearInterval 所需的 ID。

清除间隔计时器并在转换后显示结果(6100 毫秒)。

var degree = 1800;
var clicks = 0;

//Clear interval timer if id saved in attributes:
function clear_interval(t) {
  var interval = parseInt(t.data('interval'));
  if(interval > 0) {
    clearInterval(interval);
    t.data('interval', '');
  }
}

$(document).ready(function(){
  $('#spin').click(function(){
    clicks ++;
    var newDegree = degree*clicks;
    var extraDegree = Math.floor(Math.random() * (360 - 1 + 1)) + 1;
    totalDegree = newDegree+extraDegree;

    //Calculate result index:
    var win_num = 6 - Math.floor((totalDegree % 360 + 30) / 60);
		
    $('#wheel .sec').each(function(){
      var t = $(this);
      
      clear_interval(t);
      
      //Save timer ID in data-interval attribute:
      t.data('interval', setInterval(function () {
        var aoY = t.offset().top;
        $("#txt").html(t.html());

        if(aoY < 23.89){
          $('#spin').addClass('spin');
          setTimeout(function () { 
            $('#spin').removeClass('spin');
          }, 100);	
        }
      }, 10));
			
      $('#inner-wheel').css({
        'transform' : 'rotate(' + totalDegree + 'deg)'			
      });
    });

    //Stop updates and show result when transition already ended:
    setTimeout(function () {
      $('#wheel .sec').each(function(){
        clear_interval($(this));
      });
      $("#txt").html($('#wheel div.sec:nth-child('+win_num+')').html());
    }, 6100);
  });
});
