Question

Is there anyway I can pass a javascript variable to a Modal?

Answer 1

Option 1:

Try this.. while opening the modaldialog send the window as the parameter

showModalDialog(url,window,params);

and in the modal window

var parWin = window.dialogArguments;

now parWin contains your parent window object.

From here you can now access all data from your parent, be it variables or methods.

Option 2:

<SCRIPT LANGUAGE="JavaScript">
<!--
  var a = new Array;
  a[0]="first";
  a[1]="second";
  a[2]="third";
// -->
</SCRIPT>

And we pass the array a to the dialog box:

window.showModelessDialog('7b.html',a);

The callee 7b.html includes the following script:

<SCRIPT LANGUAGE="JavaScript">
<!--
  a = dialogArguments;
  a[0] = "fourth";
// -->
</SCRIPT>
