Problem returning variables

I'm losing many time trying to do a thing I dont know if Its possible:

C#

function botaoCarregarNotas() {
     PageMethods.verNum(verNum2);
     PageMethods.carregarNotas(verTexto);
 }
 // aqui é recebido o resultado
function verNum2(result) {
    var num = result;
    alert("num: "+num);
    return num;
 }
 // recebe texto
function verTexto(resultado){

var num = verNum2(paremeter);        // HERE IS THE PROBLEM
alert("num1: "+num);
 for(i=0; i< num; i++)
      loadNotes(resultado[i]);

Because I'm using AJAX I need to use this three functions, and I need to return num variable assigned at verNum2(), and use it at verTexto(). As I am using, its obviously wrong. - I get "num1: undefined", because I need to pass the parameter that I want to return.

How can I solve this problem ?

Of course this doesn't work. Look at it.

verNum2 takes one parameter which assigns it to a local variable and then returns it. When you are calling it in verTextTo you are not giving a parameter, which means NULL will be returned.

I know Mark.

That's why I solved the problem at server side.

int num = Convert.ToInt32(verNum());
string[] texto = new string[num+1];

texto[0] = num.ToString();

int i;

for (i = 1; i <= num; )
{
while (dr.Read())
{
texto[i] = dr[0].ToString();
i++;
}

}

and then

var num = resultado[0];
alert("num1: "+num);

for(i=1; i<= num; i++)
loadNotes(resultado[i]);

I just guess that I was able to solve the problem at client side, but ok, no prob :)

If you know then why do you ask? Stop wasting our time.

Solution 3

try this,

JavaScript

function botaoCarregarNotas_VerNum() 
{     
     PageMethods.verNum(verNum2);
}
function botaoCarregarNotas()
{
     PageMethods.carregarNotas(verTexto); 
} 
// aqui é recebido o resultado
function verNum2(result) 
{    
     var num = result;    
     alert("num: "+num);    
     return num; 
} 

// recebe texto
function verTexto(resultado)
{
      var num = botaoCarregarNotas_VerNum();        
      alert("num1: "+num); 
      for(i=0; i<num;>
          loadNotes(resultado[i]);
}

Solution 1

You are calling verNum2 without any parameters, like this:

var num = verNum2();

And because you called it without a parameter it has nothing to assign to num:

C#

function verNum2(result) {
    var num = result;
    alert("num: "+num);
    return num;
 }

Num is what you return and that is then unassigned because result was when calling it.

Good luck!

Yes I know, I guess I have to change the code on the server side :)
