1、中心坐標

```
// 獲取
console.log(mapView.center.longitude, mapView.center.latitude)

// 設置
var centerCoord = {
    longitude: 102.91835013921454,
    latitude: 24.07329419928656
};
mapView.center = $.extend(mapView.center, coord);
```

2、可視范圍

```
var extentJSON = mapView.extent.toJSON();
var ptMin = new Point({
    x: extentJSON.xmin,
    y: extentJSON.ymin,
    spatialReference: extentJSON.spatialReference
});
var ptMax = new Point({
    x: extentJSON.xmax,
    y: extentJSON.ymax,
    spatialReference: extentJSON.spatialReference
});
console.log(ptMin, ptMax);
```
