Question

我试图在一些矩形div的圆上产生一个运动。我希望如果在另一个div附近拖动div，则第二个div在用户拖动的第一个div内移动。是否有插件可以执行此操作，或者我需要生成计算2个div的位置的内容。而且，矩形div也可以是10个div而不仅仅是2个。

这是我的解决方案。

        </div>                
    </div>

此片段产生一个包含2个div的圆圈。这可以在圆形边界上移动。我希望如果用户在拖动的div触摸另一个时拖动div，它们会一起移动。我试图使用jQuery Overlaps库来获取2个div是否重叠但是我做错了。

更完整的示例将是您的工作示例：

        function rotateAnnotationCropper(offsetSelector, xCoordinate, yCoordinate, cropper){
            //alert(offsetSelector.left);

            var items = $('#dynamic-container').find('.marker');
            var i = 0;
            var cssDegs = 15;
            var rotate = 'rotate(' +cssDegs + 'deg)';

            for (i; i<items.length; i++){
                if(i == 0){
                    cssDegs = cssDegs*i;
                }else{
                    cssDegs = cssDegs+20;
                }

                console.log("cssDegs: "+cssDegs);
                rotate = 'rotate(' +cssDegs + 'deg)';
                //Imposto i gradi a tutti i punti per differenziarli al document ready

                //items[i].css("background-color","blue"); 
            }

            console.log(items);               

            $('.marker').on('mousedown', function(){
                $('body').on('mousemove', function(event){
                    //rotateAnnotationCropper($('#innerCircle').parent(), event.pageX,event.pageY, $('.marker'));
                    //rotateAnnotationCropper($('#innerCircle').parent(), event.pageX,event.pageY, $(event.target)); 
                    rotateAnnotationCropper($('#innerCircle').parent(), event.pageX,event.pageY, $(this).find('.marker-1')); 
                    var markers = $(this).find('.marker');
                });                                        
            });

            $('body').on('mouseup', function(event){ $('body').unbind('mousemove')});                     
        }); 

window.setInterval(function() {
    $('#result').text(collision($('.marker-1'), $('.marker-2')));
}, 200);


function collision($div1, $div2) {
      var x1 = $($div1).offset().left;
      var y1 = $($div1).offset().top;
      var h1 = $($div1).outerHeight(true);
      var w1 = $($div1).outerWidth(true);
      var b1 = y1 + h1;
      var r1 = x1 + w1;
      var x2 = $($div2).offset().left;
      var y2 = $($div2).offset().top;
      var h2 = $($div2).outerHeight(true);
      var w2 = $($div2).outerWidth(true);
      var b2 = y2 + h2;
      var r2 = x2 + w2;

      if (b1 < y2 || y1 > b2 || r1 < x2 || x1 > r2) return false;
      return true;
    }

要检测重叠，此代码应该有效：

function collision($div1, $div2) {
      var x1 = $($div1).offset().left;
      var y1 = $($div1).offset().top;
      var h1 = $($div1).outerHeight(true);
      var w1 = $($div1).outerWidth(true);
      var b1 = y1 + h1;
      var r1 = x1 + w1;
      var x2 = $($div2).offset().left;
      var y2 = $($div2).offset().top;
      var h2 = $($div2).outerHeight(true);
      var w2 = $($div2).outerWidth(true);
      var b2 = y2 + h2;
      var r2 = x2 + w2;

      if (b1 < y2 || y1 > b2 || r1 < x2 || x1 > r2) return false;
      return true;
    }

您可以将其应用于您的代码（替换重叠功能）。

希望它有所帮助！
