Hi, Why cant the following jquery work when I place the code in a separate function as below

I get no error but no animation.

$(document).ready(function(){
 
  var $val1=6;
  var $val2=10.3;
  var img = ["images/bcave1.png", "images/bcave2.png"];
  var indexNum=0;
  
	setInterval("animatepic1()",100);
 /*  var gameLoop = setInterval( function(){
	  $("#pic").attr("src", img[indexNum]);
      indexNum++;	
      if (indexNum >= 2) {indexNum = 0;} 
	   
	   } , 100);
	   */
  
 
   
 }); 
 
   function animatepic1(){
			 $("#pic").attr("src", img[indexNum]);
     		 indexNum++;	
      		 if (indexNum >= 2) {indexNum = 0;} 
	   
	    }

.....
<img id ="pic" src="images/bcave1.png" alt="eight ball" />

I suppose it's because indexNum and img array are defined in $(document).ready function's scope.
just change:
var indexNum=0;
//to 
window.indexNum=0;//this way you will define them in global object and they will be accessible everywhere

Open in new window

or even better move your function into ready scope and use the correct way to address a function with setInterval
$(document).ready(function(){
 
  var $val1=6;
  var $val2=10.3;
  var img = ["images/bcave1.png", "images/bcave2.png"];
  var indexNum=0;
  

  
    function animatepic1(){
			 $("#pic").attr("src", img[indexNum]);
     		 indexNum++;	
      		 if (indexNum >= 2) {indexNum = 0;} 
	   
	    }
	setInterval(animatepic1 ,100);   
 }); 
 
.....
<img id ="pic" src="images/bcave1.png" alt="eight ball" />
