js分頁頁碼算法

function get_hs_page(cur_page, total_page) {
    var result = "";
    for(var i = 1; i <= total_page; i++) {
        if(i == 2 && cur_page - 6 > 1) {
            i = cur_page - 6;
        }else if(i == cur_page + 6 && cur_page + 6 < total_page) {
            i = total_page - 1;
        }else{
            if(i == cur_page){
                result += "<li><a style='background-color:#e7e7e7;' href='/topic?page="+i+"&type=hs'>"+i+"</a></li>";
            }else{
                result += "<li><a href='/topic?page="+i+"&type=hs'>"+i+"</a></li>";
            }
            
        }
    }
    return result;
} 

注意：cur_page為當前頁，total_page為總頁數。
