设置单个值
<form action="subscribe.html" th:attr="action=@{/subscribe}"> <fieldset> <input type="text" name="email" /> <input type="submit" value="Subscribe!" th:attr="value=#{subscribe.submit}"/> </fieldset> </form>
设置多个值
<img src="../../images/gtvglogo.png" th:attr="src=@{/images/gtvglogo.png},title=#{logo},alt=#{logo}" />
以上两个的代替写法 th:xxxx
<input type="submit" value="Subscribe!" th:value="#{subscribe.submit}"/> <form action="subscribe.html" th:action="@{/subscribe}">
全部h5兼容的标签写法
<tr th:each="prod : ${prods}"> <td th:text="${prod.name}">Onions</td> <td th:text="${prod.price}">2.41</td> <td th:text="${prod.inStock}? #{true} : #{false}">yes</td> </tr>
<tr th:each="prod,iterStat : ${prods}" th:class="${iterStat.odd}? 'odd'"> <td th:text="${prod.name}">Onions</td> <td th:text="${prod.price}">2.41</td> <td th:text="${prod.inStock}? #{true} : #{false}">yes</td> </tr>
<a href="comments.html" th:href="@{/product/comments(prodId=${prod.id})}" th:if="${not #lists.isEmpty(prod.comments)}">view</a>
<div th:switch="${user.role}"> <p th:case="'admin'">User is an administrator</p> <p th:case="#{roles.manager}">User is a manager</p> <p th:case="*">User is some other thing</p> </div>
