7 Amap.vue:125:35- 解决办法
输出key和value，检查哪个是object类型，逐个排除。比如我经过输出，判断如下：
const onMouseOver = (event, marker) => {let jsonString = JSON.stringify(event, function(key, value) {//console.log(key+", "+value);if (key === 'target') {return undefined; // 忽略循环引用属性}return value;});console.log("event="+jsonString);jsonString = JSON.stringify(marker, function(key, value) {//console.log(key+", "+value);if (key === 'context'|| key === '_map'|| key == '_parent' ) {return undefined; // 忽略循环引用属性}return value;});
