Get name of selected RadioButton in Dialog

[#1]

Hi everyone,

I'm trying to implement a dialog with a couple of radioButtons in one radioButtonGroup. After pressing "Ok" the selected RadioButton-Name should be displayed in the formular.

I can't figure out a way to get the name of the radioButton and pass it to the form.

Here is what i got so far:

commit: function(dialog) {

     // i need the radio button name here

},

description:{

     name: "Auswahl Schnittstellen",

     elements:[

          {type: "cluster", name: "ABS", elements:[

              {type: "view", align_children: "align_left", elements: [

              {type: "radio", name: "name1", group_id: "rado"},

              {type: "radio", name: "name2", group_id: "rado"},

              {type: "radio", name: "name3", group_id: "rado"},

              {type: "radio", name: "name4", group_id: "rado"},

          ]}

     ]}

]}...

Hi,

You still need to specify the item_id attribute for the radio buttons, so I would do this like;

function dialog() {

    var descriptor = {

        commit: function(dialog) {

            var elements = dialog.store();

            dialogObject.nam1 = elements["nam1"];

            dialogObject.nam2 = elements["nam2"];

            dialogObject.nam3 = elements["nam3"];

            dialogObject.nam4 = elements["nam4"];

        },

        description:{

         name: "Auswahl Schnittstellen",

         elements:[

              { type: "ok_cancel" },

              { type: "cluster", name: "ABS", elements:[

                  { type: "view", align_children: "align_left", elements: [

                      { type: "radio", name: "name1", group_id: "rado", item_id:"nam1" },

                      { type: "radio", name: "name2", group_id: "rado", item_id:"nam2" },

                      { type: "radio", name: "name3", group_id: "rado", item_id:"nam3" },

                      { type: "radio", name: "name4", group_id: "rado", item_id:"nam4" }]}

            ]}

        ]}

    }

    var dialogObject =

    {

        execDialog: function() { return app.execDialog(descriptor); },

        }; 

    return dialogObject;

}

var d = dialog();

d.execDialog();

console.println(d.nam1);

console.println(d.nam2);

console.println(d.nam3);

console.println(d.nam4);

There will only be one of the four set to true, but it's the item_id that returns the value not the group_id.

Hi,

First of all, thanks for your solution! But now i have more that 20 radiobuttons, therefore this solution get quiet confusing. I was hoping there was a possibility to return the group_id and read the selected radiobutton out of its information.

I will try to make it work with your solution, but if you find a way to handle it just with the group_id, i would be curious to hear it!

Thanks in advance!

Hi,

I am not aware of a way to do this using the dialog object, though there are a lot of undocumented methods and properties some of which are shown here, Adobe LiveCycle Designer Cookbooks by BR001: execDialog 

But you should be able to get the result you want with a bit of JavaScript;

function dialog() {

    var radioButtonList = [ { type: "radio", name: "name1", group_id: "rado", item_id:"nam1" },

                            { type: "radio", name: "name2", group_id: "rado", item_id:"nam2" },

                            { type: "radio", name: "name3", group_id: "rado", item_id:"nam3" },

                            { type: "radio", name: "name4", group_id: "rado", item_id:"nam4" } ]

    var descriptor = {

        commit: function(dialog) {

            var elements = dialog.store();

            var radioButtonIds = radioButtonList.map(function (entry) { return entry.item_id } )

            for (var i=0, limit=radioButtonIds.length; i < limit; i++) {

                              if (elements[radioButtonIds[i]] == true) {

                 dialogObject.rado = radioButtonIds[i];     

                                   break;

               }

            }

        },

        description:{

         name: "Auswahl Schnittstellen",

         elements:[

              { type: "ok_cancel" },

              { type:"cluster", name: "ABS", elements:[

                  { type: "view", align_children: "align_left", elements: [

                    { type: "static_text", name: "Choose one:" }]

                    .concat(radioButtonList)

                    .concat([ { type: "static_text", name: "some more stuff..." } ])

                }

            ]}

        ]}

    }

    var dialogObject =

    {

        rado: null,

        execDialog: function() { return app.execDialog(descriptor); },

         }; 

     return dialogObject;

}

var d = dialog();

d.execDialog();

console.println(d.rado);

In this example I build up the dialog object with the concat() method, so I can access the item_id in the commit() method.
