矢量图形的show和hide事件使用AMap.event.addDomListener绑定不了

circle.on('show',function(){

console.log('圆形显示了');

});

circle.on('hide',function(){

console.log('圆形隐藏了');

});

------------------------------------------------------------------------------上面正常可以触发

------------------------------------------------------------------------------下面就不可以

AMap.event.addDomListener(circle,'show',function(){

console.log('圆形显示了');

});

AMap.event.addDomListener(circle,'hide',function(){

console.log('圆形隐藏了');

});
