Javascript 当我将鼠标悬停在标记上时，如何更改某些标记的标记大小

我有一些传单标记，我从数据库中解析它，但问题是当我在上面悬停时，它会改变标记的大小，但如果我在另一个标记上悬停，大小是相同的..我能做什么？我不知道这件事。谢谢

        function addScoala1(){ 
   var scoala = JSON.parse('<?php echo json_encode($scoala) ?>');
   for(var i=0; i<scoala.length; i++) {
    var greenIcon = new L.Icon({
  iconUrl: 'https://static1.squarespace.com/static/540ed918e4b0daae9995d1d7/54ecab60e4b0feaa477dac5a/54ecab79e4b0c686e92227d7/1424796549381/university.png',
  shadowUrl: 'https://cdnjs.cloudflare.com/ajax/libs/leaflet/0.7.7/images/marker-shadow.png',
  iconSize: [35, 40],
  iconAnchor: [12, 41],
  popupAnchor: [1, -34],
  shadowSize: [10, 10]
});
    var marker = L.marker( [scoala[i]['latitudine'], scoala[i]['longitudine']], {icon: greenIcon}).addTo(groupA);
    marker.bindPopup( "<b>" + scoala[i]['scoala']+"</b><br>Detalii:" + scoala[i]['detalii'] + "<br />Telefon: " + scoala[i]['telefon']);
    L.Icon.Big = L.Icon.extend({
    options: {
    iconSize: new L.Point(44, 61),
    iconUrl: 'https://static1.squarespace.com/static/540ed918e4b0daae9995d1d7/54ecab60e4b0feaa477dac5a/54ecab79e4b0c686e92227d7/1424796549381/university.png',
  shadowUrl: 'https://cdnjs.cloudflare.com/ajax/libs/leaflet/0.7.7/images/marker-shadow.png'
}});

      var bigIcon = new L.Icon.Big();
      groupB.eachLayer(function (layer) {
      marker.on('mouseover', function (e) {
            this.openPopup();
            marker.setIcon(bigIcon);
    });
        marker.on('mouseout', function (e) {
            this.closePopup();
            marker.setIcon(greenIcon);
        });
      });

 }
  }

函数addScoala1（）{
var scoala=JSON.parse（“”）；
对于（var i=0；i尝试使用resetStyle，而不是重置上一个图标。
查看文档以了解详细信息：

 layer.on('mouseout', function (e) {
                this.closePopup();
                 marker.resetStyle(e.target);
                });
            }
