Performing action after getting value of button

Question

Can anyone tell me whats wrong with this code? Ive already got it to alert the value of the button by using alert(y) and getting back 2437 but as soon as i put this condition statement in its not even giving me an alert.

Im sure its something simple but im not seeing it.

jQuery(document).ready(function( $ ){
   if( $('body.single-product').length || $('body.single-product').length ){
   var x = document.getElementsByClassName("single_add_to_cart_button");
   var y = x[0].value;
   if y == 2437 {
     alert("Yes");
   }else{
     alert("No");
   }
  }
});

Answer 1

You have an error in your javascript code right here: if y == 2437

Correct it to this:

jQuery(document).ready(function( $ ){
 if( $('body.single-product').length || $('body.single-product').length ){
   var x = document.getElementsByClassName("single_add_to_cart_button");
   var y = x[0].value;
   if (y == 2437) {
     alert("Yes");
   }else{
     alert("No");
   }
 }
});
