Even it is not a good way of doing what you want try this hint  var url   MUST BE A NUMER FIRST  function nextImage     url   url   1    location href  http   mywebsite com     url   html

What you re doing is appending a  1   the string  to your URL  If you want page 1 html link to page 2 html you need to take the 1 out of the string  add one to it  then reassemble the string   Why not do something like this   var url    http   mywebsite com 1 html   var pageNum   parseInt  url split      pop   10    var nextPage    http   mywebsite com    pageNum 1    html     nextPage will contain the url http   mywebsite com 2 html in this case  Should be easy to put in a function if needed

Your example wasn t working because you are trying to add 1 to a string that looks like this   1 html    That will just get you this  1 html1  which is not what you want   You have to isolate the numeric part of the string and then convert it to an actual number before you can do math on it   After getting it to an actual number  you can then increase its value and then combine it back with the rest of the string   You can use a custom replace function like this to isolate the various pieces of the original URL and replace the number with an incremented number   function nextImage         return window location href replace    d     html     function str  p1  p2            return  Number p1    1    p2                You can then call it like this   window location href   nextImage      Demo here  http   jsfiddle net jfriend00 3VPEq   This will work for any URL that ends in some series of digits followed by  html and if you needed a slightly different URL form  you could just tweak the regular expression

This is more robust   mi   location href split    d      no   mi length - 2  os   mi no   mi no     if   mi no        length  lt  os length  mi no    os match  0      mi no   location href   mi join        When the URL has multiple numbers  it will change the last one     http   mywebsite com 8815 1 html   It supports numbers with leading zeros   http   mywebsite com 0001 html   Example
