Modal popup dialog window with multiple parameters

Introduction

This article shows a modal popup dialog window which passes and returns multiple parameters. This sample creates parent and child webforms. The child webform is called modally by the parent passing multiple values to the child form. The child form displays the passed values allowing them to be edited and then returns the altered values back to the parent when finished. The child form is modal to only the parent form. To make the child modal to the entire desktop, see the below final note.

    window.close();
    }
    function doInit() {
    var ParmA = "Aparm";
    var ParmB = "Bparm";

    var MyArgs = new Array(ParmA, ParmB, ParmC);
    MyArgs =  window.dialogArguments;

    <BODY onload="doInit()">
    <P>Param A:<INPUT id="tbParamA" TYPE="text"></P>
    <P>Param B:<INPUT ID="tbParamB" TYPE="text"></P>
    <P>Param C:<INPUT ID="tbParamC" TYPE="text"></P>

Final Note

To make the child modal to the entire desktop, you'll need add code to the child which uses <body onblur="this.focus">.
