織夢讀取數據庫幾個用法

調取ID爲16 標題長度爲40 簡介長度爲50 降序desc（升序asc）的第一條（ 第2到5條爲limit=’1,4’ ）

{dede:arclist typeid='16'  titlelen='40' infolen='50'   orderway='desc' limit='0,1' }
      <img src="[field:picname/]"  width="158" height="119">
            <a href="[field:arcurl /]" title="[field:fulltitle /]" >[field:title /]</a>
            <dd>[field:description function="cn_substr(Html2text(@me),180)"/]...</dd>         
{/dede:arclist}

ID15 20條 簡介50 標題10

{dede:arclist row="20" typeid="15" titlelen="10" infolen="50"}
<li><a href="[field:typeurl/]" title="[field:fulltitle/]" >[[field:typename/]]</a><a href="[field:arcurl /]">[field:title /]</a></li>
{/dede:arclist}

自動獲取頁面提交的時間

<input name="hzlytime" type="text" class="bor" />
            <script language="javascript" type="text/javascript">
 var c=new Date().toLocaleString();
 document.write("<input type='hidden' name='hzlytime' id='hzlytime' value= '"+c+"'/>");
</script>

列表ID等於1加特別css style=display:block

 {dede:arclist row=6   typeid='20'  titlelen='80'   orderway='desc'  addfields='sydt'  channelid='1' }
    <div class="sci2contL" id="con_zj_[field:global.autoindex/]"    [field:global name=autoindex runphp="yes"](@me==1)? @me="style=display:block":@me="";[/field:global]><a href="#"><img src="[field:sydt/]"  width="610" height="360"></a></div>
    {/dede:arclist}

調取某條ID爲156新聞的自定義字段

{dede:arclist typeid='49' idlist='156' addfields='trueprice,brand,yfty,yfwy,yftr,yfwe,yfts,yfws,yftss,yfwss,yftw,yfww,yftl,yfwl' channelid='6' }
[field:yfwy/]
{/dede:arclist}

根據頁面ID 顯示不同的內容

<div {dede:field name='typeid' runphp='yes'} if(@me==24) @me='style=display:block'; else @me='style=display:none'; {/dede:field}  >
typeid爲24顯示
</div>
<div {dede:field name='typeid' runphp='yes'} if(@me==39) @me='style=display:block'; else @me='style=display:none'; {/dede:field}  >
typeid爲39顯示
</div>

根據瀏覽器地址對應導航顯示不同css樣式(GetNavigationk)

<div >
  <ul>
    <li id="kNav1"><a href="/">網站首頁</a></li>
     <li id="kNav2"><a href="html/abouts">關於我們</a></li>
      <li id="kNav3"><a href="html/news">新聞資訊</a></li>
      <li id="kNav4"><a href="html/case">服務產品</a></li>
  </ul>
</div>
<script type="text/javascript">
//導行樣式指定
function GetNavigationk(kUrlStr){
  var kNavUrl = window.location.href;
  if(kNavUrl.indexOf("ttttttttttttt")!=-1){var ControlNumk = 1;}
  else if(kNavUrl.indexOf("html/abouts")!=-1){var ControlNumk = 2;}
  else if(kNavUrl.indexOf("html/news")!=-1){var ControlNumk = 3;}
  else if(kNavUrl.indexOf("html/case")!=-1){var ControlNumk = 4;}
  else {var ControlNumk = 1;}
  return ControlNumk; 
}
var ControlIDk = "kNav"+GetNavigationk(window.location.href); 
document.getElementById(ControlIDk).className="style_1";
</script>

根據瀏覽器地址對應導航顯示不同css樣式(GetNavigation)

<div id="PARENT">
          <ul id="nav">
            <li id="Nav1"><a href="/html/news/major/">集團要聞</a></li>
            <li id="Nav2"><a href="/html/news/brief/">集團簡訊</a></li>
            <li id="Nav3"><a href="/html/news/media/">媒體報道</a></li>
            <li id="Nav4"><a href="/html/news/calling/">業內動態</a></li>
            <li id="Nav5"><a href="/html/news/notice/">公示公告</a></li>
            <li id="Nav6"><a href="/html/news/special/">專題報道</a></li>
          </ul>
 </div>

<script language="javascript">
//導行樣式指定
function GetNavigation(UrlStr){
    var NavUrl = window.location.href;  
    if(NavUrl.indexOf("news/major")!=-1){var ControlNum = 1;}   
    else if(NavUrl.indexOf("news/brief")!=-1){var ControlNum = 2;}  
    else if(NavUrl.indexOf("news/media")!=-1){var ControlNum = 3;}  
    else if(NavUrl.indexOf("news/calling")!=-1){var ControlNum = 4;}    
    else if(NavUrl.indexOf("news/notice")!=-1){var ControlNum = 5;} 
    else if(NavUrl.indexOf("news/special")!=-1){var ControlNum = 6;}    
    else {var ControlNum = 0;}
    return ControlNum; 
}
window.onload = function(){ 
    var ControlID = "Nav"+GetNavigation(window.location.href);  
    document.getElementById(ControlID).className="style_2";
}
</script>

根據瀏覽器地址打印不同的文字

<script type="text/javascript">
//命名規則
function GetNavigationk(CUrlStr){
    var CNavUrl = window.location.href;
    if(CNavUrl.indexOf("news/major")!=-1){document.write("集團簡訊");}
    else if(CNavUrl.indexOf("news/brief")!=-1){document.write("集團要聞");}
    else if(CNavUrl.indexOf("news/media")!=-1){document.write("媒體報道");}
    else if(CNavUrl.indexOf("news/calling")!=-1){document.write("業內動態");}
    else if(CNavUrl.indexOf("news/notice")!=-1){document.write("公示公告");}
    else if(CNavUrl.indexOf("news/special")!=-1){document.write("專題報道");}
    else {document.write("資訊中心");}
    return ControlNumk; 
}
{ 
    var ControlIDk = "pNav"+GetNavigationk(window.location.href); 
}
</script>

網站導航當前欄目顯示class=’navhover’

<a href="{dede:global.cfg_basehost/}" title="{dede:global.cfg_webname/}" {dede:field name=typeid runphp="yes"}(@me=="")? @me=" class='navhover'":@me="";{/dede:field}>網站首頁</a>
{dede:channel type='top' row='8' currentstyle="<a href='~typelink~' class='navhover' >~typename~</a>"}
<a href='[field:typeurl/]'>[field:typename/]</a>
{/dede:channel}
