[mapguide-users] Create programmatically a map

[Ivan Milicevic]

Hello,

You can change href of mapFrame. Here is sample code.

var mapa = "cijevi"; //defines map name
var stringMape = "Library%3a%2f%2fPROJEKTI%2fSUPRANET%2fMAPE%2f" + mapa;
var hrefMapa =
"http://172.21.10.3/mapguide/mapviewernet/mapframe.aspx?MAPDEFINITION="
+ stringMape +
".MapDefinition&TYPE=HTML&SHOWLEGEND=0&SHOWPROP=0&INFOWI
DTH=0&LOCALE=en&HLTGT=1&HLTGTNAME=&SHOWSLIDER=0&SESS
ION=" + mgSessionId + ";

//changing mapFrame href
mapFrame.location.href = hrefMapa;


Hope this helps.

Hi Kenneth,
I need again your help about my problem.

I think the problem is that after new map run-time creation in library
repository, I cannot use its map definition to create its web layout.

How can I assign the new map to the layout?

Thanks again, Fabio
