1. ng-template 是angular4中的用于获取#id的值，例子如下：
<
ng-template
let-col
let-monitor=
"rowData"
pTemplate=
"body"
>
<
input #
chk
type=
"checkbox" (
change)=
"regularChecked(monitor,chk)"
/>
</
ng-template
>
2.如果用到父子组件传值，父组件中用到子组件nc-overlay-panel等
<
nc-overlay-panel
class=
"monitor-panel" [
panelTitle]=
"chartPanelTitle" [
show]=
"true"
>
</
nc-overlay-panel
>
子组件nc-overlay-panel中要写入类似router-outlet类似的占位符
<
div
class=
"overlay-panel" *
ngIf=
"show"
>
<!-- content -->
<
div
class=
"overlay-panel-content"
>
<
ng-content
></
ng-content
>
</
div
>
</
div
>
3. arcgis发布的服务图片切片，已经包含经纬度，无须重新定位图片到地图上
4. 添加地图右上角条件，切片条件的tianjia，和内容，效果图如图所示：
在leafletservice中定义_layersControl
if (
leafletOptions.
layersControl) {
this.
_layerControl =
this.
_L.
control
.
layers(
layers.
baseLayers,
layers.
overlays, {
collapsed:
true })
.
addTo(
this.
_map);
}
addOverlay(
layer:
any,
layerName:
string) {
this.
_layerControl.
addOverlay(
layer,
layerName);
}
const
layer1 =
L.
esri.
tiledMapLayer({
url:"",
maxZoom:
19
});
setTimeout(()
=> { //必须要使用上setTimeout()，
this.
leafletService.
addOverlay(
layer1,
"2018年2月");
},
500);
5. 往地图定位图标中加入id属性
const
marker =
L.
marker(
[
Number(
item[
"10.2"]),
Number(
item[
"20.1"])],
{
icon:
"url"
}
);
//==往marker中加入id和type属性==
Object.
defineProperties(
marker, {
id: {
value:
1
},
type: {
value:
"小武"
}
});
6. 地图上调到指定位置，可以定位很多定位集中的地方
//把所有的marker全部添加到layer集合中
this.
heatMarkerLayer.
addLayer(
marker);
//把layer集合添加到地图上
this.
leafletService.
map.
addLayer(
this.
heatMarkerLayer);
//地图定位到指定地点
this.
leafletService.
zoomToExtent(
this.
leafletService.
getLayerBounds(
this.
heatMarkerLayer)
);
zoomToExtent(
extent:
any) {
this.
_map.
flyToBounds(
extent);
}
7. 从后台请求的值分别赋值
//==分别对应element中的Time,DispName等属性==
const {
Time,
DispName,
HumanHotspotId } =
element;
8 触发定位图标的点击事件
//==fire() :触发指定类型的事件。你可以提供一个数据对象——监听器对象的第一个参数应该包含它的属性。==
layer.
fire(
"click");
9. 禁止leaflet地图的拖拽事件
//==拖拽地图事件给禁止==
this.
map.
dragging.
disable();
