加載foot模塊頁(yè)
#parse("foot.vm")

#foreach($item in $tables)
?#set($strEnd = $item.Length - 1)
?#set($sheetName = $item.Substring(0, $strEnd))
?<option value="$item">$sheetName</option>
#end

$strEnd也可以看做一個(gè)字符串來(lái)操作
$item.Substring(0,15) 取出從0開(kāi)始的15個(gè)字符
------------------------------------------------------------------------------------------
//$listType才能用ToString()時(shí),不能用$!{listType}不會(huì)出錯(cuò)不能被ToString();
//$listType.toString('f2')，四舍五入，保留兩小數(shù)。toString();可以加很多的參數(shù)，查查參數(shù)表.
#if($listType.ToString() == "List")
?#foreach($item in $items)
?<li><a href="FindByPosition.page?positionId=$!{item.Id}">$!{item.PositionName}</a></li>
?#end
#elseif($listType.ToString() == "Select")
?<select id="position" name="employee.Position">
?<option value="-1">請(qǐng)選擇</option>
?#foreach($item in $items)
?<option value="$!{item.Id}">$!{item.PositionName}</li>
?#end
?</select>
#end

//#foreach()的循環(huán)用法。
<select id="sels">
?#foreach($time in [1..$checkorder.TimeCount])
??<option value=$time>$time</option>
?#end
</select>

2008-1-5:作VTL表達(dá)式，Castle工程
VTL表達(dá)式不區(qū)分大小寫(xiě)，可以調(diào)用方法，屬性，
//$velocityCount是統(tǒng)計(jì)循環(huán)的次數(shù),從１弄開(kāi)始計(jì)算
#set($foo="Holle") ${foo}world
##:是單行注釋。#**#:多行注釋。
<table>
#foreach($info in $array)
?<tr>
?<td>$velocityCount ##統(tǒng)計(jì)循環(huán)的次數(shù)從1開(kāi)始計(jì)</td>
?<td>$!{info.name}</td>
?<td>$!{info.Password}</td>
?<td>$!{info.Age}</td>
?<td>$!{info.getvalue}</td>
?</tr>
#end
</table>
循環(huán)Hashtable是的用法
$allProducts是Hashtable的對(duì)象
#foreach($var in $allProducts)
?##var.key：獲取鍵 var.value：獲取值
?$!{var.key}->$!{var.value}
#end
//另一種Hashtable的循環(huán)用法
vm頁(yè)面用關(guān)鍵字點(diǎn)鍵名。
<h3>$!{hash.aa}</h3>
<h3>$!{hash.bb}</h3>
<h3>$!{hash.cc}</h3>
<h3>$!{hash.dd}</h3>
Controll層里
public void Index()
{
?Hashtable hash = new Hashtable();
?hash.Add("aa","one");
?hash.Add("bb",DateTime.MaxValue);
?hash.Add("cc",DateTime.MinValue);
?hash.Add("dd",DateTime.Now.ToString());
}
-------------------------------------------------------------------------------------
##是可以用來(lái)輸出字面的意思是原樣輸出（注釋用的）
#literal()
#foreach($woogie in $boogie)
?nothing will happen to $woogie
#end
#end
-----------------------------------------------------------------------------------------
//$type里面的一些方法，比較有用。
#if($type.ToLower() != "noservice")? ToLower():是小寫(xiě)字符串的方法。
ToString():
#set($index=$item.Content.IndexOf(","))
$!{item.ReceiveTime.ToString("yyyy-mm-dd HH:mm")}
$!{consumeLog.OperateDate.ToString("yyyy-MM-dd HH:mm")}
$!{consume.ConsumeDate.ToString("d")}
$!{consume.ConsumeDate.ToString("t")}
$!{sign.FirstStartTime.ToShortDateString()}與$!{sign.FirstStartTime.ToString("yyyy-MM-dd")}效果一樣的。
#set($index = $customer.IndexOf(","))取得逗號(hào)位置
$r.Phone.Substring(0,7)****：取出電話號(hào)碼為:1371093****
-----------------------------------------------------------------------------------------
this.ProprtBag.Add("time",DateTime.Now);
//用來(lái)判斷是否為空
#if($time!="")
?<h1>$!time</h1>
#end
//當(dāng)有數(shù)組是判斷是否是數(shù)
#if($items.Count>0)
?#foreach($item in $items)
??$!{item}
?#end
#end
-----------------------------------------------------------------------------------------
#elseif：多重條件判斷
#if(!$order)
?100001
#elseif($order.CustomerId && $order.CustomerId != "" && $order.CustomerId != $userName)
?100002
#elseif($order && ($order.CustomerId == "" || !$order.CustomerId || $order.CustomerId == $userName))
?100003
#end
-----------------------------------------------------------------------------------------------------
用<!--? -->:來(lái)注釋頁(yè)面上用的，不能有套用會(huì)無(wú)法注釋的如：<!-- <!-- --> -->
---------------------------------------------------------------------------------------------------------
//會(huì)依次顯示，當(dāng)翻頁(yè)面時(shí)也會(huì)接著上一頁(yè)繼續(xù)顯示編號(hào)。其中14為每一頁(yè)顯示的條數(shù)，根據(jù)需要而調(diào)整
#if(!$page || $page <= 0)
?#set($page = 1)
#end
#set($rowIndex = ($page - 1) * 14 )
#foreach($log in $logDt.Rows)
?$rowIndex
#end
---------------------------------------------------------------------------------------------------------
$!{consumeLog.OperateDate.ToString("yyyy-MM-dd HH:mm")}
---------------------------------------------------------------------------------------------------------
#if(!$log.UserName || $log.UserName == "")
?<a title="邀請(qǐng)會(huì)員激活空間" href="javascript:sendMessage('$!{log.CardId}')"><img alt="未綁定" src="../images/noTies.gif" /></a>
