jquery variable in function

rated 0 times [ 97] [ 7] / answers: 1 / hits: 17189 / 12 Years ago, thu, april 5, 2012, 12:00:00

On pageload I set a variable

$(document).ready(function() {

  var inv_count = 3;

  });

When I try to refer to that variable inside functions though, it doesn't work.

function blah(a,b) {

   alert (inv_count);

   }

Why is this? And how can I get around it?

If you declare a variable inside a function, the variable name will be inaccessible outside the scope of that function. Move the declaration outside the function:

var inv_count;

$(document).ready(function() {

    inv_count = 3;

});
