javascript - CSS fix for webgrid's pager method using Razor and MVC3

I am using MVC3 with Razor, for display a grid I am using a WebGrid, and for paging for this very grid I am using the following code.

My problem : The paging-buttons should keep the same size both when they are selected/clicked and when they are not selected/clicked.

I am having some css problems, I have used CSS and javascript to achieve a design which my client wanted I have replicated it at this fiddle link /

Razor Code

@grid.Pager(mode: WebGridPagerModes.All, numericLinksCount: 15, firstText: "<<", lastText: ">>", previousText: "<", nextText: ">")

My CSS Code body { font-family: Calibri; background-color: #D8D8D8; margin-top: 0px; text-decoration:none; }

    #footer:not([href]) {
    letter-spacing: 0px;
    }

    #footer {
    text-align: center;
    margin-top: 10px;
    }

    .pagingCss {
    font-size: 13px;
    }

    .whiteBox {
    background-color: 
    white;
    color: 
    black;
    padding-right: 7px;
    padding-left: 7px;
    padding-top: 4px;
    padding-bottom: 4px;
    text-decoration: none;
    margin-top: 10px;
    letter-spacing: 0px;
    }

    .blackBox {
    background-color: 
    black;
    color: 
    white;
    padding-right: 7px;
    padding-left: 7px;
    padding-top: 4px;
    padding-bottom: 4px;
    text-decoration: none;
    margin-top: 10px;
    letter-spacing: 0px;
    }

    .pagingCss a {
    font-size: 13px;
    color: white;
    text-decoration:none;
    }

Javascript Code I have used

    var keywords = ['>>', '<<', '<', '>'];

    function linklabels() {

        var footerDiv = document.getElementById('footer');
        var oldLinks = footerDiv.getElementsByTagName('A');

        var oldLinksCount = oldLinks.length;
        var keywordsCount = keywords.length;

        for (var i = 0; i < oldLinks.length; i++) {

            if (oldLinks[i].firstChild.nodeValue == '>>' || oldLinks[i].firstChild.nodeValue == '<<' || oldLinks[i].firstChild.nodeValue == '>' || oldLinks[i].firstChild.nodeValue == '<') {
                var my_div = null;
                var newDiv = null;

                var newDiv = document.createElement("span");
                var newContent = document.createTextNode(oldLinks[i].firstChild.nodeValue);
                newDiv.appendChild(newContent);
                newDiv.className = "whiteBox";

                oldLinks[i].firstChild.nodeValue = "";

                oldLinks[i].appendChild(newDiv);
            }
            else {
                var my_div = null;
                var newDiv = null;

                var newDiv = document.createElement("span");
                var newContent = document.createTextNode(oldLinks[i].firstChild.nodeValue);
                newDiv.appendChild(newContent);
                newDiv.className = "blackBox";

                oldLinks[i].firstChild.nodeValue = "";

                oldLinks[i].appendChild(newDiv);
            }

        } // end of for

        //  footer

    }
    window.onload = linklabels;

Here is how my HTML is render after using the above code

and the code is rendered as html is below

<div id="footer" class="pagingCss">

<a href="/CompanySearch/Home/Results?page=1">
    <span class="whiteBox">&lt;&lt;</span>
</a>

<a href="/CompanySearch/Home/Results?page=5">

As I said in the ments,

don't try to heal the symptoms. In your case a CSS fix won't do the trick because there is no selector for text nodes.

a quick jquery fix would to the trick though:

$(function() {  
 $("#footer").contents().filter(function() {

     var $this = $(this);
     return $this.children().length == 0 && $.trim($this.text()).length > 0;

 }).wrap("<span class='selectedBox' />");       
});

This will wrap your lone text element with a span with class selectedBox for which you have to add some css. You can see it in action here.

UPDATE here is a plete solution This also replaces your linklabels javascript code:

function isNumber(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

$(function() {  
 $("#footer a").contents().wrap("<span class='blackBox' />");
 $("#footer").find("a span").each(function(){
    var val = $.trim($(this).text());
    if (!isNumber(val))
       $(this).attr('class', 'whiteBox');      
  });    

 $("#footer").contents().filter(function() {

     var $this = $(this);
     return $this.children().length == 0 && $.trim($this.text()).length > 0;

 }).wrap("<span class='whiteBox' />");       
});

The selected number is displayed without a wrapping element, so it´s rendered inline.

Try wrapping it in a span tag like this: http://jsfiddle/Z5L4g/2/

I have wrapped the selected number in a span with class selected, which shares the same rules as the blackbox class, except having transparent background and black text color.

I wouldn't say it´s a CSS problem, but a markup problem. The selected page indicator doesn't get any width or height and can't be styled as it is just text.

Suggestion: either change the markup, or split the innerHTML of the #footer with javascript and work from there. I would go with the first option.
