As I said in the comments  a  lt div gt  element does not have a value attribute  Although  very  bad  it can be accessed as   console log document getElementById  demo   getAttribute     I suggest using HTML5 data-  attributes rather  Something like this    lt div id  demo  data-myValue  1  gt     lt  div gt    in which case you could access it using   element getAttribute  data-myValue      Or using jQuery      demo   data  myValue

DIVs do not have a value property   Technically  according to the DTDs  they shouldn t have a value attribute either  but generally you ll want to use  getAttribute   in this case   function overlay         var cookieValue   document getElementById  demo   getAttribute  value        alert cookieValue

First of all   lt div id  demo  align  center   value  1  gt  lt  div gt    that is not valid HTML  Read up on custom data attributes or use the following instead    lt div id  demo  align  center  data-value  1  gt  lt  div gt    Since  data-value  is an attribute  you have to use the getAttribute function to retrieve its value   var cookieValue   document getElementById  demo   getAttribute  data-value

To put it short  value  is not an valid attribute of div   So it s absolutely correct to return undefined   What you could do was something in the line of using one of the HTML5 attributes  data-     lt div id  demo  align  center   data-value  1  gt    And the script would be   var val   document getElementById  demo   getAttribute  data-value      This should work in most modern browsers Just remember to put your doctype as  lt  DOCTYPE html gt  to get it valid
