Mentiray opened a new issue #9751: geo切换底图后监听底图缩放问题
URL: https://github.com/apache/incubator-echarts/issues/9751
 
 
   var myChart = null;
   function showChart(xzqhdm){
   	if(myChart!=null){
   		myChart.dispose();
   	}
   	$.get('json/'+xzqhdm+'.json',function(DTJSON){
   		echarts.registerMap(xzqhdm,DTJSON);
   		var myChart = echarts.init(document.getElementById('demo'));
   		var option = {
   			geo:{
   				map : xzqhdm,
   				roam : true,
   			}
   		};
   		myChart.setOption(option);
   		myChart.on('geoRoam', function(){
   			console.log('监听到缩放操作');
   		});
   	});
   }
   //切换底图
   $('#button1').click(function(){
   	showChart('350000');
   })
   $('#button2').click(function(){
   	showChart('350100');
   })
   
   如果没有切换底图，一次缩放操作geoRoam就执行一次
   如果n次切换底图，一次缩放操作geoRoam就会执行n次这是为什么？？？
