Question

I have a simple piece of Javascript code and I get this Error :

Uncaught ReferenceError: i is not defined (anonymous function)

The code is as below –

    function xyz(i){
    ....
    ....

    if(i==5) {  // do something }
    else {
      i=i+1;
    setTimeout("xyz(i)",10)

    }


   xyz(1);

Can someone please help me ? Do I need to declare ‘i’ somewhere ?

Answer 1

The error is in the setTimeout function. Try this, instead:

setTimeout(function(){
    xyz(i);
},10)

Always choose an anonymous function instead of a “stringed function”
