Thymeleaf的内置属性

Thymeleaf是另一个Java视图模板引擎,使用上和FreeMarker各有千秋,不了解的可以从其他博文里学习一下。我这里主要记录一下它的内置属性。

 本文不是Thymeleaf入门教程,也不是对其标签进行全面讲解只对其属性等价标签进行记录,以为辞典。

 

Thymeleaf提供了一个标签th:attr,可以把多个DOM标签用逗号分隔后写进去:

<img src="../../images/gtvglogo.png"
th:attr="src=@{/images/gtvglogo.png},title=#{logo},alt=#{logo}" />

 这个例子里给<img>标签设置了三个属性标签:src、title、alt。<img>自带的src会被Thymeleaf处理后扔掉而使用自己的。

 

这个标签不太优雅,不仅写起来紊乱,读起来也凌乱。所以很少用,一般用其他的代替:

 

<img src="../../images/gtvglogo.png"
th:src="@{/images/gtvglogo.png}" th:title="#{logo}" th:alt="#{logo}" />

 作为th:attr的实例用法,Thymeleaf提供了几乎全部标签的Thymeleaf等价标签:

th:abbr th:accept th:accept-charset
th:accesskey th:action th:align
th:alt th:archive th:audio
th:autocomplete th:axis th:background
th:bgcolor th:border th:cellpadding
th:cellspacing th:challenge th:charset
th:cite th:class th:classid
th:codebase th:codetype th:cols
th:colspan th:compact th:content
th:contenteditable th:contextmenu th:data
th:datetime th:dir th:draggable
th:dropzone th:enctype th:for
th:form th:formaction th:formenctype
th:formmethod th:formtarget th:frame
th:frameborder th:headers th:height
th:high th:href th:hreflang
th:hspace th:http-equiv th:icon
th:id th:keytype th:kind
th:label th:lang th:list
th:longdesc th:low th:manifest
th:marginheight th:marginwidth th:max
th:maxlength th:media th:method
th:min th:name th:optimum
th:pattern th:placeholder th:poster
th:preload th:radiogroup th:rel
th:rev th:rows th:rowspan
th:rules th:sandbox th:scheme
th:scope th:scrolling th:size
th:sizes th:span th:spellcheck
th:src th:srclang th:standby
th:start th:step th:style
th:summary th:tabindex th:target
th:title th:type th:usemap
th:value th:valuetype th:vspace
th:width th:wrap th:xmlbase
th:xmllang th:xmlspace  

 比如:

<form action="subscribe.html" th:action="@{/subscribe}">
<a href="product/list.html" th:href="@{/product/list}">Product List</a>

 这里使用了th:action和th:href标签。

 

Thymeleaf还提供了两个合成标签:

th:alt-title th:lang-xmllang

 用于同时设置两个属性,比如;

<img src="../../images/gtvglogo.png"
th:src="@{/images/gtvglogo.png}" th:alt-title="#{logo}" />

 还有两个CSS标签:

 

 th:classappend  th:styleappend

意思显而易见,用法如下:

<tr th:each="prod : ${prods}" class="row" th:classappend="${prodStat.odd}? 'odd'">

 

 

对于判断性的标签,比如checked

<input type="checkbox" name="option1" checked="checked" />

 只能使用checked作为其值,即使使用true都不好使。Thymeleaf提供了这些标签的等价标签,值可以是判断语句,不为真会删除该标签:

 

th:async th:autofocus th:autoplay
th:checked th:controls th:declare
th:default th:defer th:disabled
th:formnovalidate th:hidden th:ismap
th:loop th:multiple th:novalidate
th:nowrap th:open th:pubdate
th:readonly th:required th:reversed
th:scoped th:seamless th:selected

比如:

<input type="checkbox" name="active" th:checked="${user.active}" />
