当然也是在保证this.placeSearch和this.geoCoder（即AMap.Geocoder和AMap.PlaceSearch）都加载到，同样也是上面说的笨办法。我是先用AMap.PlaceSearch.search方法，通过关键字查询传入的地址，如果查询到，则确定新的地图中心点经纬度，再通过AMap.Geocoder.getAddress方法传入新的地图中心点经纬度，解析出省市区信息，也可能关键字查询不明确（未明确省市区），比如只写了xx路，就有可能在全国多处都有结果，则会关闭弹框，提示明确后再查询，还可能关键字根本就查询不到，AMap.PlaceSearch.search返回no_data，则传入关键字使用AMap.Geocoder.getLocation方法，解析关键字所在城市，总之这里的逻辑就是AMap.Geocoder和AMap.PlaceSearch搭配使用。此处this.getAreaInfo方法是解析地址省市区的方法，设置了一个回调函数作为参数：
//依赖高德该接口获得省市区信息
getAreaInfo(type, callback) {
if(type === 'address') { // 在编辑的情况下通过地址名称查询
this.geoCoder.getLocation(this.handleCityName, (status, result) => {
if (status === 'complete' && result.geocodes.length) {
this.ruleForm.regeocode.adcode = result.geocodes[0].adcode
this.ruleForm.regeocode.province = result.geocodes[0].addressComponent.province
this.ruleForm.regeocode.city = result.geocodes[0].addressComponent.city == '' ? result.geocodes[0].addressComponent.province : result.geocodes[0].addressComponent.city
this.ruleForm.regeocode.district = result.geocodes[0].addressComponent.district;
callback(result);
} else if(status === 'no_data') {
this.lists = [];
this.onCloseModal();
this.$message.info('未能查询到该地址，请更换关键字查询');
} else {
this.fixedPosition();//精准定位或IP地址定位
}
});
} else if(type === 'location') { // 在查看的情况下通过经纬度查询
this.geoCoder.getAddress(this.center, (status, result) => {
if (status === 'complete' && result.regeocode && result.regeocode.addressComponent) {
this.ruleForm.regeocode.adcode = result.regeocode.addressComponent.adcode
this.ruleForm.regeocode.province = result.regeocode.addressComponent.province
this.ruleForm.regeocode.city = result.regeocode.addressComponent.city == '' ? result.regeocode.addressComponent.province : result.regeocode.addressComponent.city
this.ruleForm.regeocode.district = result.regeocode.addressComponent.district;
callback(result);
} else {
this.fixedPosition();//精准定位或IP地址定位
}
});
}
},
以上在获取到地址时都会设置为一个地址列表，设置在地图左侧，供用户选择，滚动使用better-scroll，可以上拉加载进行分页，这里不展开说了。
通过以上步骤，大部分情况下都能查询到精确的关键字，一部分高德没有收录的企业信息，也能定位到所在街道乡镇省市区。此外还在点击地图的时候触发了AMap.PlaceSearch.searchNearBy方法查询鼠标点击处的周边，作为补充：
// 查看更多，此方法也给上拉加载使用
searchMore(e) {
if(e) {
this.isUseNearBy = true;
this.placeSearch.opt.pageIndex = 1;
this.center = [e.lnglat.getLng(), e.lnglat.getLat()];
} else {
this.placeSearch.opt.pageIndex += 1;
}
this.geoCoder.getAddress(this.center, (status, result) => {
if (status === 'complete' && result.info === 'OK') {
let addressComponent = result.regeocode.addressComponent;
this.ruleForm.regeocode.adcode = addressComponent.adcode
this.ruleForm.regeocode.province = addressComponent.province
this.ruleForm.regeocode.city = addressComponent.city == '' ? addressComponent.province : addressComponent.city
this.ruleForm.regeocode.district = addressComponent.district;
let cityName = this.isUseNearBy ? '' : this.handleCityName;
if(this.isUseNearBy) {
this.placeSearch.searchNearBy(cityName, this.center, 1000, (status, result) => {
this.searchCallBack(status, result, e)
});
} else {
this.placeSearch.search(cityName, (status, result, e) => {
this.searchCallBack(status, result)
});
}
} else {
this.emptyLocationData();
}
})
},
searchCallBack(status, result, event) {
if (status === 'complete' && result.poiList.pois.length) {
if(event) {
this.lists = result.poiList.pois;
if(this.lists.length % this.pageSize !== 0) {
this.bottomLineShow = true;
} else {
this.bottomLineShow = false;
}
this.getAddress(0);
if(this.scroll) {
this.scroll.scrollTo(0, 0);
this.scroll.finishPullUp();
} else {
this._initScroll();
}
this.addMarker();
} else {
this.lists = concat(this.lists, result.poiList.pois);
if(this.lists.length % this.pageSize !== 0) {
this.bottomLineShow = true;
} else {
this.bottomLineShow = false;
}
this.originalStatus();
}
} else {
this.bottomLineShow = true;
}
},
主要的部分就是上面这些，还有一些里面用到的方法，我截几张图吧，第一次写文章，写的比较乱。
