设置属性值
原始表单
<form action="subscribe.html">
<fieldset>
<input type="text" name="email" />
<input type="submit" value="Subscribe me!" />
</fieldset>
</form>
我们可以通过th:attr来设置input或者form或者其他标签的属性。如:
<form action="subscribe.html" th:attr="action=@{/subscribe}">
<fieldset>
<input type="text" name="email" />
<input type="submit" value="Subscribe me!" th:attr="value=#{subscribe.submit}"/>
</fieldset>
</form>
他会替换相同属性的值。结果如下:
<form action="/gtvg/subscribe">
<fieldset>
<input type="text" name="email" />
<input type="submit" value="¡Suscríbeme!"/>
</fieldset>
</form>
当然,有的时候我们需要一次设置多个属性。怎么办?通过“,”隔开:
<img src="../../images/gtvglogo.png"
th:attr="src=@{/images/gtvglogo.png},title=#{logo},alt=#{logo}" />
结果是:
<img src="/gtgv/images/gtvglogo.png" title="Logo de Good Thymes" alt="Logo de Good Thymes" />
通过特殊属性设置
上面的设置值方式很通用,但是很丑陋。
<input type="submit" value="Subscribe me!" th:attr="value=#{subscribe.submit}"/>
我们提供th:*这样的方式来替代th:attr。th:attr在项目中一般不建议使用。比如th:value
<input type="submit" value="Subscribe me!" th:value="#{subscribe.submit}"/>
是不是比th:attr要简单些,同事避免你打错属性。同样的。
<form action="subscribe.html" th:action="@{/subscribe}">
<li><a href="product/list.html" th:href="@{/product/list}">Product List</a></li>

同时设置多个属性值

或者这样
<img src="../../images/gtvglogo.png"
th:src="@{/images/gtvglogo.png}" th:alt-title="#{logo}" />
追加后面和追加前面的属性
th:attrappend 后面追加
th:attr
前面追加
例如:cssStyle=warning,追加后面
<input type="button" value="Do it!" class="btn" th:attrappend="class=${' ' + cssStyle}" />
即为
<input type="button" value="Do it!" class="btn warning" />
这里还有两种类似的特殊属性th:classappend 和th:styleappend
<tr th:each="prod : ${prods}" class="row" th:classappend="${prodStat.odd}? 'odd'">
固定值,boolean属性
有一些特殊属性的值是固定的。比如checked:
<input type="checkbox" name="option1" checked="checked" />
<input type="checkbox" name="option2" />
用法:
<input type="checkbox" name="active" th:checked="${user.active}" />
固定值,boolean类型属性列表如下:
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
html5的data语法支持
属性可以在HTML5中用这种方式写:data-{prefix}-{name}
<table>
<tr data-th-each="user : ${users}">
<td data-th-text="${user.login}">...</td>
<td data-th-text="${user.name}">...</td>
</tr>
</table>
