Thymeleaf的內置屬性（轉）

Thymeleaf是另外一個Java視圖模板引擎，使用上和FreeMarker各有千秋，不瞭解的能夠從其餘博文裏學習一下。我這裏主要記錄一下它的內置屬性。

 本文不是Thymeleaf入門教程，也不是對其標籤進行全面講解只對其屬性等價標籤進行記錄，覺得辭典。

 

Thymeleaf提供了一個標籤th:attr，能夠把多個DOM標籤用逗號分隔後寫進去：

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

 這個例子裏給<img>標籤設置了三個屬性標籤：src、title、alt。<img>自帶的src會被Thymeleaf處理後扔掉而使用本身的。

 

這個標籤不太優雅，不只寫起來紊亂，讀起來也凌亂。因此不多用，通常用其餘的代替：

 

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

 做爲th:attr的實例用法，Thymeleaf提供了幾乎所有標籤的Thymeleaf等價標籤：

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

 好比：

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

 這裏使用了th:action和th:href標籤。

 

Thymeleaf還提供了兩個合成標籤：

th:alt-title

th:lang-xmllang

 用於同時設置兩個屬性，好比；

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

 還有兩個CSS標籤：

 

th:classappend

th:styleappend

意思顯而易見，用法以下：

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

 

 

對於判斷性的標籤，好比checked

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

 只能使用checked做爲其值，即便使用true都很差使。Thymeleaf提供了這些標籤的等價標籤，值能夠是判斷語句，不爲真會刪除該標籤：

 

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

好比：

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