[mapserver-users] Rosa and javascript

[Hankley, Chip]

Here's an example. I have a "print" icon that calls another PHP page,
passing some parameters, to create a "print friendly" version of the map.
All the button does is launch the JS function.

I imagine you *could* pass variable to the function as well.

To see this in action, go to the URL below.

NOTE!
The default configuration of the app does NOT use Java, so you'll need to
click the little Java button on the right side of the page to get the ROSA
applet to load. Then click the print icon to see the functionality. Also, it
probably won't work in anything less than NS 6 or IE 5.

The pertinent part of the APPLET code:

<APPLET NAME="RosaApplet" ARCHIVE="/java/rosa/rosa.jar" CODE="Rosa2000"
  WIDTH="450" HEIGHT="450" MAYSCRIPT style="border-style: inset;
border-width: 4">

    <!-- a bunch of other buttons... -->

    <PARAM NAME="TB_BUT_print_IMG" VALUE="/MapSymbols/PrintOff.gif">
    <PARAM NAME="TB_BUT_print_IMG_PR" VALUE="/MapSymbols/PrintOff.gif">
    <PARAM NAME="TB_BUT_print_HINT" VALUE="Print this Image">
    <PARAM NAME="TB_BUT_print_INPUT" VALUE="submit">
    <PARAM NAME="TB_BUT_print_NAME" VALUE="CMD">
    <PARAM NAME="TB_BUT_print_JSACTION" VALUE="fnxPrint()">
    <PARAM NAME="TB_BUT_print_VALUE" VALUE="PRINT">
  </APPLET>

The JavaScript function:

function fnxPrint() {
  //Gather some variables
  var map;
  var xmin;
  var xmax;
  var ymin;
  var ymax;

  xmin = document.frmMapInfo.C_XMIN.value;
  xmax = document.frmMapInfo.C_XMAX.value;
  ymin = document.frmMapInfo.C_YMIN.value;
  ymax = document.frmMapInfo.C_YMAX.value;
  map = 'arsenic.map';

 
window.open('print.php?&Mapfile='+map+'&XMIN='+xmin+'&XMAX='+xmax+'&YMIN='+y
min+'&YMAX='+ymax,'')
}

Cheers!

Chip

Hi there,
Reading rosa applet documentation, I saw that it was possible to call a
javascript function from a rosa applet button using the JSACTION parameter.
But I haven't able to use it properly yet. Could someone give me a hint ?
Thanks
