<p>map object??</p>
<p>i've popped up using alert(this.extent) but depending on where you insert that alert() in mapserv.js its value changes! i've looked through <a href="http://maps.dnr.state.mn.us/tools/dbox/docs/jsdocs/">http://maps.dnr.state.mn.us/tools/dbox/docs/jsdocs/
</a> but can't get the values contained in the map object. is there a dbox guru lurking on this list ;)?</p>
<p>i've also tried making my own zoombox but can't get the zoombox to follow the cursor if the cursor is dragged from right-bottom to left-top in the negative direction. any help with that?</p>
<div>i admit this is not strictly a mapserver question but then again there's no dbox list. <br>jzs<br><span class="gmail_quote"></span></div>

<br>requesting a new map image. So the new extent needs to be calculated<br>on the client (the browser). Thanks to mapserv.js, this is no harder<br>than requesting the new values from the server, and a lot more<br>elegant. The extent, scale, size, etc. are contained in the map
<br>object, and are updated each time you make a new map request.<br><br>But by not relaoding the whole page, the browser's back and forward<br>buttons don't do what you would expect, and you can not book mark the<br>URL. There are a couple thing you might try: you could maintain a
<br>"history" stack and add your own back & forward buttons to your user<br>interface (ArcIMS, MapBuilder, and many others do this), or you could<br>try pushing the current map parameters into the browser's history.
<br>Don't know what problems you'd encounter, but that always seemed more<br>elegant to me. I just haven't gotten around to trying to implemet it.<br><br>Rich<br><br>--<br>Richard Greenwood<br><a href="mailto:richard.greenwood@gmail.com">
