Can you show us the source of the “Textt()” function?

Have you tried seeing if Textt(Temp_J) actually returns a value before you try to insert it in to the JSON object?

immmm completing to my first q , i supposed have these :

var text4 = ["File", "Edit", "Help","Save", "View", "Find"];
var text5 = ["Print", "Close", "Paste","HEART","HEARS","SEARS","STARS","STARE","STORE","STONE"];

and our function is :


function Textt(num)
{

//alert(num);

   switch(num)
	{
	case 4:
 	document.write(text4[r]); 
 	 break;
	case 5:
	document.write(text5[r]); 
	 break;
	default:
	document.write("Item!");
 
	}

i want that these above array add to the Json Arry

You’re going to want to return a value from the Textt() function rather than using document.write

e.g.


function Textt(num) {
  switch(num)  {
    case 4:
      return text4[r]; 
    case 5:
      return text5[r]; 
    default:
      return "Item!"
  }  
}

Additionally, where is the variable r being set? You’ll need to make sure that it’s available in the Textt() function.

r is counter
when is called this function, it will increase 1

function Textt(num)
{
r=r+1;
}

my problem is in this line :
J.myMenu[b]={“title”:Textt(Temp_J) , “popMenu”:[{“title”:Textt(Temp_J), “popMenu”:[{“title”:Textt(Temp_J)}]}]};

how i can add item in Json array from other array

function Textt(num)
{
r=r+1;
//alert(num);

switch(num)
{
case 4:
document.write(text4[r]);
break;
case 5:
document.write(text5[r]);
break;
}

You’ll need to return the values from Textt() like I showed you in my previous post. When you do that, Textt() will, instead of writing the value to the page, output it to the array.
