Script Error: func.apply is not a function

[Rocco Cogliano]

I don't understand this error.

The error occurs when a function call for the second time . 

The function loops through a list and count the occurrences of certain text strings.

Hi Rocco,

I think you will have to post some code, so we can see what you are doing.

Hi Dave,

thank you for reply.

I have a list with items that I get with a QR code scan and then the  function loops through list and count the occurrences of certain text strings.

This is the simply code:

function riepilogoListaDispositivi(_lst)

{

                

    /*var marcheAccelerometri = [

                {}

                ];

   

    var modelliDispositivi = [

               {episensor:0, CMG5T:0, a131A_02_3:11, }

               ];

               

          app.Alert(modelliDispositivi[0].a1); */

          

    for (var i=0;;i++)

    {

        var rec = _lst.GetItemByIndex(i);

        if(rec==undefined) break;

        str1=rec.title; //lettura del title degli items

        str2=rec.body; //lettura del body degli items

        

        arr1=str1.split('SN:');

        serial=arr1[1];

        //app.Alert('SN: '+serial);

        

        arr2=arr1[0].split(' ');

        marca = arr2[0];

        modello = arr2[1]

        //app.Alert('Marca: '+marca);

        //app.Alert('Modello: '+modello);

        

        arr3=str2.split(' di ');

        TipoDispositivo=arr3[0];

        arr4=arr3[1].split(' IDdsp:');

        Afferenza=arr4[0];

        IdTipoDispositivo=arr4[1];

        arrNumDispositivi[IdTipoDispositivo-1]++;// conto i vari tipi in lista

    }

    txtRiepilogo = 'In lista sono presenti \n';

    for (i=0;i<11;i++)

    {

        if (arrNumDispositivi[i]>0)

        {

            txtRiepilogo = txtRiepilogo + arrNumDispositivi[i]+ ' ' + nomiTipiDispositivi[i]+'\n';

        }  

    }

    //app.Alert(txtRiepilogo);

    return txtRiepilogo;

}

and this vars in global space:

var i=0;

var arrNumDispositivi = [0,0,0,0,0,0,0,0,0,0,0,0,0,0];

/*

numAccelerometro=0;

numAcquisitore=0;

numAllInOne=0;

numBatteria=0;

numCavo=0;

numGps=0;

numPannello=0;

numRegolatore=0;

numSede=0;

numSismicaAttiva=0;

numVelocimetri=0;

numKit=0;*/

var nomiTipiDispositivi = [     

        'Accelerometri', //0

     'Acquisitori',     //1

     'AllInOne',     //2

     'Batterie',     //3

     'Cavi',     //4

     'Gps',  //5

     'Pannelli',     //6

     'Regolatori',       //7

     '....',             //8

     'Sismica attiva',   //9        

     'Velocimetri',      //10

            'Kit'               //11

            ];

and this is a screenshot of list where it's possible to see the list items

No idea?

I can't see anything in the code you have posted that accounts for this error.

Are you able to post the whole app, possibly as an spk?

If your app is private, would you be prepared to mail it to me directly?

[Rocco Cogliano]

Hi Steve,
sorry for my late reply, but I was traveling.
I found error in my code and I solved it. The error due to the fact that a function contained a variable that had the same name of the function. Thanks a lot for your answer and again forgive me for my late response.

Best regards
R

Thanks for the feedback, Rocco.

It is useful to know a likely cause of that exact message.

[Rocco Cogliano]

The error results from not explicit declaration of a variable within the function and the variable has the same name as the function .

It is rightly so .

for example:

function OnStart()

{

lay = app.CreateLayout( "linear", "VCenter,FillXY" );

btn = app.CreateButton( "Press Me", 0.3, 0.1 );

lay.AddChild( btn );

//Set function to call when button pressed.

btn.SetOnTouch( f );

//Add layout to app.

app.AddLayout( lay );

}

//Called when user touches our button.

function f()

{

    f=0;         // <============== ERROR

    //var f=0;  // <============== OK

    // g = 0     // <============== OK 

//Show a message.

app.ShowPopup( "Hello World!" );

}

It's my fault.

Beginner's mistake .
