[Chameleon] Form ElementsRene Teniere TENIERER@gov.ns.caMon, 09 Feb 2004 15:41:20 -0400

I have added this piece of code under myOnLoad() function:
function showExtents()
{
x1 = goCWCJSAPI.oMap.minx + 1000;
y1 = goCWCJSAPI.oMap.miny + 1000;
x2 = goCWCJSAPI.oMap.maxx - 1000;
y2 = goCWCJSAPI.oMap.maxy - 1000;
alert(x1+' '+y1+' '+x2+' '+y2);
goCWCJSAPI.oMap.SetExtents(x1,y1,x2,y2);
goCWCJSAPI.oMap.Refresh();
x1 = goCWCJSAPI.oMap.minx;
y1 = goCWCJSAPI.oMap.miny;
x2 = goCWCJSAPI.oMap.maxx;
y2 = goCWCJSAPI.oMap.maxy;
alert(x1+' '+y1+' '+x2+' '+y2);
}
I am using this as a test to try and get familiar with this method. It
only works up till goCWCJSAPI.oMap.SetExtents(x1,y1,x2,y2);. Am I going
about this the right way? Like I say, the ultimate goal is to load up
the page using a set of custom extents each time.

Is there any way to do it through HTML? All of my extents are through
a
JS variable. Here is my html file to give you reference:

>From that, hopefully you can see what I'm getting at. This page is
loaded up from a separate html file using window.open(). If I do use
php, HTML form elements, or CWCJSAPI, could I do it within this page??

Hi Rene,
If I understand your requirements correctly I think you can use the
applyBoundingBox javascript function. This function can be seen in
BoundingBoxPopup.widget.php on line 229. Essentially, you pass the
bbox
coords to the function and it handles submitting and zooming.
