DWZ (JUI) pagination to determine if the maximum number of pages is exceeded

To modify the code in Dwz.pagination.js:

$this. Find (setting.jumpto$). each (function () {
    var$this= $ (this);
    Var$inputbox = $this. Find (": Text");
    Var$button = $this. Find (": Button");
    $button. Click (Function (event) {
        Varpagenum = $inputBox. val ();
        if (Pagenum && Pagenum.ispositiveinteger ()) {
            //determine if greater than total number of pages, if greater than then jump to the first page @ketayao if
            (Pagenum > Pc.numpages ()) {
                pagenum = 1;
            }
            Determine if greater than total number of pages, if greater than then jump to the first page @ketayao
            dwzpagebreak ({targetType:pc.targetType (), Rel:pc.rel (), data: {pagenum: Pagenum}});
    $inputBox. KeyUp (function (event) {
        if (Event.keycode = = DWZ.keyCode.ENTER) $button. Click ();
    })
;

Of course you can also do other jump logic.
