How to set up a default value in execDialog

Dear All,

I need to show a default value in the first field of two of the execDialog function.

Is there a way to do this ?

Thanks in advance,

//Sample of what I am looking for :

var dialogTitle = "Please confirm";

var defaultAnswer = "No.";

var reply = app.response("Did you really mean to type that?", dialogTitle, defaultAnswer);

//Script I need to modify for showing a variable in the first field :

var dialogmdp = {
initialize: function (dialog) {
// Showing the date.
var todayDate = dialog.store()["date"];
todayDate = "Date: " + util.printd("dd mmmm, yyyy", new Date());
dialog.load({ "date": todayDate });
},
commit:function (dialog) {
var results = dialog.store();
},
