Looking for a JS Map control with a callback
<p>I was wondering if anyone knows of a good Javascript/Query map control that will allow the user to click on a position. Once this is done the control would callback with the GPS coordinates that the user just selcted.</p>

<p>Does anyone know of such a control.</p>

<p>I have been looking about but haven't found anything yet.</p>

<p>This is to use in a MVC3 application.</p>

<p>All suggestions welcome.</p>
