FreeMarker中文API手册(完整) http://blog.csdn.net/junjun16818/article/details/6990068
拆分字符数组
<#if (lineInfo.lineDate?exists)&&(lineInfo.lineDate?length>10)>
<#list lineInfo.lineDate?split(",") as d>
<input type="text" name="lineInfo.lineDate" id="lineDate" value="${d}" onclick="WdatePicker({dateFmt:'yyyy-MM-dd', skin:'whyGreen'})"/>
</#list>
</#if>
1.注释：
包含在<#--和-->
2.注意：
由于Freemarker会将>解释成FTL标记的结束字符，所以对于>和>=可以使用括号来避免这种情况，例如
<#if (x > y)>
3.<#local y = "test"> 定义局部变量
4.<#import "/lib/my_test.ftl" as my> 导入模板文件 指定名字空间 my
5. if指令
<#if animals.python.price < animals.elephant.price>
Pythons are cheaper than elephants today.
<#else>
Pythons are not cheaper than elephants today.
</#if>
6. list指令以及列表序号
<#list animals as being>
第${being_index+1}个<#--默认是0开始-->
<tr><td>${being.name}<td>${being.price} Euros
</#list>
<#list ["winter", "spring", "summer", "autumn"] as x>
${x}
</#list>
<#list ["Joe", "Fred"] + ["Julia", "Kate"] as user>
- ${user}
</#list>
输出结果是：
- Joe
- Fred
- Julia
- Kate
include指令
<#include "/copyright_footer.html">
7.判断是否为空
${userInfo.userName?if_exists}
<#if ((user.sex)!'')=='1'>男<#elseif ((user.sex)!'')=='2'>女</#if>
<#if searchType ? exists && searchType=='on'>checked</#if>
<#if time ? exists && (time!'')=='y' || (time!'')=='m' || (time!'')=='d'>统计条件<#else>保证金返款数量</#if>
<#if ((time)!'')=='y'>按年统计<#elseif ((time)!'')=='m'>按月统计<#elseif ((time)!'')=='d'>按日统计<#else>默认按日统计</#if>
8.截取字符串
${carInfo.carNum.substring(0,1)}
9.freemarker的replace功能
替换字符串 replace
线路标签：${lineInfo.lineLableDescribe?replace('#','、')}
${s?replace(‘ba’, ‘XY’ )}
${s?replace(‘ba’, ‘XY’ , ‘规则参数’)}将s里的所有的ba替换成xy 规则参数包含: i r m s c f 具体含义如下:
· i: 大小写不区分.
· f: 只替换第一个出现被替换字符串的字符串
· r: XY是正则表达式
· m: Multi-line mode for regular expressions. In multi-line mode the expressions ^ and $ match just after or just before, respectively, a line terminator or the end of the string. By default these expressions only match at the beginning and the end of the entire string.
· s: Enables dotall mode for regular expressions (same as Perl singe-line mode). In dotall mode, the expression . matches any character, including a line terminator. By default this expression does not match line terminators.
· c: Permits whitespace and comments in regular expressions.
10.三目运算
${true?string('5','7')}
11.string格式化单个Interpolation，下面是一个例子：
<#setting number_format="currency"/>
<#assign answer=42/>
${answer}
${answer?string} <#-- the same as ${answer} -->
${answer?string.number}
${answer?string.currency}
${answer?string.percent}
输出结果是：
$42.00
$42.00
42
$42.00
4,200%
12.插入日期值：根据缺省格式（由#setting指令设置）将表达式结果转换成文本输出；可以使用内建函数string格式化单个Interpolation，下面是一个使用格式模式的例子：
