Add numeric pager to jqGrid

Question

Does anyone know of a way to set up jqGrid to use a numeric pager?

Instead of Page 1 of 20, I want to have the paging be like 1,2,3,4 > >> and when I click on 4 it w

Answer 1

Ohhh! During I wrote the code firegnom posted another implementation. Nevertheless better two working versions as no one.

I made small demo which demonstrate how the behavior with links in the pager can be implemented. I made the code so, that it can display the pager either in the form

(if pginput: false parameter of jqGrid are used) or in the form

In both cases the current page will not displayed in the list. How one can see I inserted the underlined style for the links. If you don't like it you should remove

td.myPager a { text-decoration:underline !important }

from the demo. The working live demos you can see here and here.

The corresponding JavaScript code is full inside of loadComplete event handler:

loadComplete: function() {
    var i, myPageRefresh = function(e) {
        var newPage = $(e.target).text();
        grid.trigger("reloadGrid",[{page:newPage}]);
        e.preventDefault();
    };

    $(grid[0].p.pager + '_center td.myPager').remove();
    var pagerPrevTD = $('<td>', { class: "myPager"}), prevPagesIncluded = 0,
        pagerNextTD = $('<td>', { class: "myPager"}), nextPagesIncluded = 0,
        totalStyle = grid[0].p.pginput === false,
        startIndex = totalStyle? this.p.page-MAX_PAGERS*2: this.p.page-MAX_PAGERS;
    for (i=startIndex; i<=this.p.lastpage && (totalStyle? (prevPagesIncluded+nextPagesIncluded<MAX_PAGERS*2):(nextPagesIncluded<MAX_PAGERS)); i++) {
        if (i<=0 || i === this.p.page) { continue; }

        var link = $('<a>', { href:'#', click:myPageRefresh });
        link.text(String(i));
        if (i<this.p.page || totalStyle) {
            if (prevPagesIncluded>0) { pagerPrevTD.append('<span>,&nbsp;</span>'); }
            pagerPrevTD.append(link);
            prevPagesIncluded++;
        } else {
            if (nextPagesIncluded>0 || (totalStyle && prevPagesIncluded>0)) { pagerNextTD.append('<span>,&nbsp;</span>'); }
            pagerNextTD.append(link);
            nextPagesIncluded++;
        }
    }
    if (prevPagesIncluded > 0) {
        $(grid[0].p.pager + '_center td[id^="prev"]').after(pagerPrevTD);
    }
    if (nextPagesIncluded > 0) {
        $(grid[0].p.pager + '_center td[id^="next"]').before(pagerNextTD);
    }
}

where grid and MAX_PAGERS are defined as

var grid = $("#list"), MAX_PAGERS = 2;

Answer 2

as far as i know there is no solution for that in jquery and you have to do it yourself . below i have working code for the pager :

function jqgridCreatePager(pagernav,navgrid,pages){
    $('#'+pagernav+' #'+pagernav+'_center td:has(input)').attr('id','pager');
    var td = $('#'+pagernav+' #'+pagernav+'_center #pager').html('');
    var page = parseInt(jQuery("#"+navgrid).jqGrid('getGridParam','page'))
    var lastPage = parseInt(jQuery("#"+navgrid).jqGrid('getGridParam','lastpage'))
    text='';
    if(page-pages > 1){
            text+=jqgridCreatePageLink(navgrid,1)
            text+= ' ... '
    }
    for(var i=0;i <pages;i++){
        if(page-pages+i >=1)
            text+=jqgridCreatePageLink(navgrid,page-pages+i)
    }

    text +=jqgridCreatePageLink(navgrid,page,true);

    for(var i=0;i <pages;i++){
        if(page+i+1 <= lastPage) 
            text +=jqgridCreatePageLink(navgrid,page+i+1)
    }

    if(page+pages <= lastPage){
        text+= ' ... '
        text+=jqgridCreatePageLink(navgrid,lastPage)

    }
    var td = $('#'+pagernav+' #'+pagernav+'_center #pager').html(text);
}

and function which is making links

function jqgridCreatePageLink(navgrid,page,current){
    if (!current)
        return ' <a href="#" onclick="jQuery(\'#'+navgrid+'\').jqGrid(\'setGridParam\',{page:'+page+'}).trigger(\'reloadGrid\')">'+page+'</a> ';
    return ' >'+page+'< '
}

now to integrate this code with grid just add it when grid is created gridComplete event or something like that:

//create 
jqgridCreatePager('yourGridNavigator','yourGrid',3)

and also attach it to onPage event

//onPage
jqgridCreatePager('yourGridNavigator','yourGrid',3)

to prevent flickering just add to your css

#yourGridNavigator_center{
 display:none;
}

and again on gridComplete just add

$('#yourGridNavigator_center').show();

as to the function patrameters:

• first is your grid navigator id
• second is your grid id
• this third parameter of the function is how many pages should be displayed before and after current page

And here's one more possible solution.

It replaces the paging textbox with a list of links.

loadComplete: function() {
    var grid = this;
    var container = jQuery("#prev_jqGridTablePager").next().next();
    jQuery(container).html('');

    var totalPages = grid.p.lastpage;
    for (var i = 1; i <= totalPages; i++) {
        if (i == grid.p.page) {
            jQuery(container).append("<span class='pagination current'>" + i + "</span>");
        } else {
            jQuery(container).append("<a class='pagination' href='javascript: void(0)'>" + i + "</a>");
        }
    }

    jQuery(container).find("a.pagination").click(function(e) {
        e.preventDefault();

        var newPage = jQuery(this).text();
        jQuery(grid).trigger("reloadGrid", [{ page: newPage }]);
    });
}
