Javascript paging code example sharing (js paging)_javascript skills

Call:

Copy code The code is as follows:

var pageChange = function (index) {
         html = pager("divid", index, 5, 1000, pageChange, { showGoTo: false, showFirst: false });
    }

Implementation:

Copy code The code is as follows:

showFirst: true, //In totalPage>barSize Whether to automatically display the first page link
showLast: true, // Whether to automatically display the last page link when totalPage>barSize
showGoTo: true, // Whether to display GoTo
autoHideGoTo: true / /If there are too few, whether to automatically hide GoTo
