核心提示:特性可设定私有缓存或公共缓存,提高效率可自由选择使用 Stream 组件或 fso 组件支持自定义文件编码可保存文件属性Name文本,ASP通用模板类,该模板名称,主要用于使用公共缓存时区分不同模板,从私有缓存载入,当开启并存在公共缓存时,Format文本,文件编码类型

特性
可设定私有缓存或公共缓存,提高效率
可自由选择使用 Stream 组件或 fso 组件
支持自定义文件编码
可保存文件

属性


Name
文本,该模板名称,主要用于使用公共缓存时区分不同模板。


Format
文本,文件编码类型,可设置值。


Object
文本,使用组件,可设置值:


Stream
FSO

PublicCache
布尔值,使用公共缓存,开启时模板文件将保存到application对象,其他引用此模板类的对象设置相同Name值并同样打开公共缓存即可从缓存读取。(Load方法)


PRivateCache
布尔值,使用私有缓存,开启时模板文件将保存到对象内部变量,同一引用此模板类的对象可读取。(Load方法)


Direction
文本,模板文件所在目录,前后无需斜杠或反斜杠,如:template/default


File
文本,模板文件名,前边无需斜杠或反斜杠,如:default.html


SaveDirection
文本,保存文件所在目录,前后无需斜杠或反斜杠,如:html/default


SaveFile
文本,保存文件名,前边无需斜杠或反斜杠,如:default.html

对象


Code
文本,当前文本,使用SetVar方法时对此对象进行替换,使用Load方法时将模板重载到此对象


Storage
文本,已保存文本,使用SaveFront或SaveLast方法时将Code对象中文本保存到此对象的开头或结尾,可用于循环后得到所有代码

方法


ClearCache
清除公共缓存和私有缓存(强制从文件重载模板)


ClearPublicCache
清除公共缓存


ClearPrivateCache
清除私有缓存


ClearCode
清除Code对象


ClearStorage
清除Storage对象


SaveFront
将当前Code对象中文本保存到Storage对象开头


SaveLast
将当前Code对象中文本保存到Storage对象结尾


SaveCode
将当前Code对象中文本保存到文件


SaveStorage
将当前Storage对象中文本保存到文件


SetVar
对当前Code对象中文本进行替换
参数:需要被替换的文本,欲替换后的文本


Load
将模板文件载入Code对象,当开启并存在私有缓存时,从私有缓存载入,当开启并存在公共缓存时,从公共缓存载入,若无缓存则从文件载入

内部变量


ccStrPath
默认根目录


ccStrCookieName
默认Application对象名前缀

Dim objTemplate
Set objTemplate = New ccClsTemplate

'开启缓存
objTemplate.PublicCache = True

'载入模板
Call objTemplate.Load
'进行文本替换
Call objTemplate.SetVar("<#test#>","Hello world.")
'将文本保存至Storage暂存
Call objTemplate.SaveLast
'重新载入模板,此时将从私有缓存重新装载,提高效率
Call objTemplate.Load
'替换为其他值
