Javascript Gmaps缩放功能(Javascript Gmaps Zoom Function)

嗨，我正在尝试创建一个函数，我要求用户输入他希望地图放大的缩放值，但似乎这不起作用。 有什么建议吗？ 谢谢。

function zoomto() { map.SetOptions({zoom: parseInt(prompt('zoom value'))}); }

这是我的按钮

<input type="button" id="zoomto" value="zoom" onclick="zoomto()"/>

Hi I am trying to create a function where I ask the user to input the zoom value that he wants the map to zoom in but it seems that this is not working. Any advice on it ? Thanks.

function zoomto() { map.SetOptions({zoom: parseInt(prompt('zoom value'))}); }

and here is my button

<input type="button" id="zoomto" value="zoom" onclick="zoomto()"/>

最满意答案

尝试这个：

function zoomto() { map.set('zoom', parseInt(prompt('zoom value'))); }

Try this:

function zoomto() { map.set('zoom', parseInt(prompt('zoom value'))); }
