阻止鼠标悬停事件的重叠圆圈 - 谷歌地图v3

时间：2015-02-05 19:08:52

标签： google-maps google-maps-api-3 javascript-events mouseover geometry

我的代码中有一个重叠的圆圈，在一个较大的圆圈内有四个其他较小的圆圈，而在这四个其他圆圈中还有无数其他较小的圆圈。 创建这样的圆的方法针对三种类型中的每一种读取不同的阵列，从而创建用于圆圈的鼠标悬停和鼠标移除事件的方法，在其创建中调用。 我的问题：该事件仅在较小的圈子中运行。 当我评论创造他人的呼吁，并为他们的个人创造他们的工作，但不是在一起。

您需要将圈子传递给setMouseOver函数，并为每个圈执行此操作，以便每个圈子都有自己的鼠标悬停监听器。

function setMouseOverEvent(draw_circle) {
  google.maps.event.addListener(draw_circle, 'mouseover', function(e) {
    this.setOptions({
      fillColor: "#000"
    });
  });

  google.maps.event.addListener(draw_circle, 'mouseout', function(e) {
    this.setOptions({
      fillColor: this.fillColor0
    });
  });
}

  map = new google.maps.Map(document.getElementById('map-canvas'),
    mapOptions);

  setMarkers(map, posMarkers); //seta os marcadores no mapa
  setCircleSituacao(map);
  setCircleAtributos(map, posAtributos);

}
