问题 My map has several hundred markers within a city. Usually no more than a 20 mile radius. I've read through the documentation and haven't found a way to set the init to automatically pan between every marker, no matter the distance. The default behavior is to pan if close, jump if far. I understand why they would do this since the map doesn't load the whole world at the selected zoom level and it could screw up if the distance was too great. However, I think it could handle 20 mile radius with

问题 I'm trying to place markers based on the latitude and longitude stored in a model on a Google Map using the API and HTML5 geolocation.

问题 I cannot figure out how to implement the search box in my google maps. I have it where the user can pick some stuff from a form and it loads the markers on the map. Now I want to add where they can type in the city and state using the google search box, like on maps.google.com. Can this be done with API v. 3? 回答1: There is no complete "widget" in Google maps for this task. But it is easy to accomplish it. In HTML you can have a text field and a button "Search". (Instead you can handle the

The only pieces of information I know and can get are: The field of view (degrees) The center point's heading and pitch (in degrees) and x and y pixel position The x and y pixel position of the mouse click I've included here a screenshot with simplified measurements as an example: I initally just thought you could divide the field of view by the

问题 I have an existing map on a page. I can select that element using something along the lines of document.getElementById() to get the HTMLElement javascript object. Is it possible to get the instance of google.maps.Map created when the map is initialised, i.e. is it a property of the HTMLElement object or in its prototype? 回答1: You can't get google.maps.Map object from DOM Element ,on which Google Maps object have been constructed. google.maps.Map is just a wrapper, which controls DOM Element
