谢谢大家的帮助~
实现 以下分页算法
1 2 3 4 5...12
这种格式显示分页链接的算法~~并不是用什么语言实现数据列表

[code="javascript"]
//生成页导航链接
var makePageLinks = function(pageIndex, pageSize, pageCount, startPageIndex, linksCount){
var links = [];
var i = 0;
var _createLink = function(text, index, pageSize){
var link = document.createElement("span");
var href = "?page=" + index + "&page_size=" + pageSize;
link.setAttribute('href', href);
link.style.cursor = "pointer";
link.appendChild(document.createTextNode(text));
bindPageLinkClickHandler(link, index);
return link;
}

    if (startPageIndex != 1) {
        var link = _createLink("Prev", pageIndex - 1, pageSize);
        links.push(link);
        links.push(document.createTextNode("..."));
    }

    while (i < linksCount && startPageIndex + i <= pageCount) {
        var index = startPageIndex + i;
        var link = _createLink(index, index, pageSize);
        if (index == pageIndex) 
            link.style.color = "red";
        links.push(link);
        i++;
    }

    if ((startPageIndex + linksCount - 1) < pageCount) {
        links.push(document.createTextNode("..."));
        var link = _createLink("Next", pageIndex + 3, pageSize);
        links.push(link);
    }
    return links;
}

//更新页导航链接
var updatePageLinks = function(rowsCount, pageSize, pageIndex){
    var pages_count = Math.ceil(rowsCount / pageSize);
    var startPageIndex = 1;
    var linksCount = 5; //生成的链接数          
    var maxStartPageIndex = pages_count - linksCount + 1;
    if (pages_count > linksCount) {
        startPageIndex = pageIndex;
        if (startPageIndex > maxStartPageIndex) {
            startPageIndex = maxStartPageIndex;
        }
        else {
            var halfLinksCount = Math.floor(linksCount / 2);
            while (startPageIndex > 1 && (pageIndex - startPageIndex) < halfLinksCount) {
                startPageIndex--;
            }
        }
    }
    var links = makePageLinks(pageIndex, pageSize, pages_count, startPageIndex, linksCount);
    var pageLinksContainer = document.getElementById($PAGE_LINKS);
    pageLinksContainer.innerHTML = "";
    for (var i = 0, l = links.length; i < l; i++) {
        pageLinksContainer.appendChild(links[i]);
    }
}
