Iterating anchors in jquery doesn't seem to work

Hai i am generating page numbers based on currentpage and lastpage using jquery ... Here is my function and as i am newbie i dont know how it can be done...

function generatePages(currentPage, LastPage) {
    if (LastPage <= 5) {
        var pages = '';
        for(var i=1;i<=5;i++)
        {
            pages += "<a class='page-numbers' href='#'>" + i + "</a>"
        }
        $("#PagerDiv").append(pages);

First of all, you have to find a correct algorithm for what you want to do and the function you posted shows that you don't have any.

The logic to implement could be:

• Display page numbers from currentPage - 2 to currentPage + 2 (limited to [1, lastPage])
• if page 1 is not is displayed, prepend "1 ..."
• if lastPage is not displayed, append "... lastPage"

And additionally, you can add that:

• if currentPage is greater than 1, prepend "prev"
• if currentPage is less than lastPage, append "next"

That's for the theory. Now, for the implementation, just use jPaginate or another pagination plugin for jQuery instead...
