thymeleaf中的th:with用法

局部变量,th:with能定义局部变量:

<div th:with="firstPer=${persons[0]}">

  <p>

    The name of the first person is <span th:text="${firstPer.name}">Julius Caesar</span>.

  </p>

</div>

当th:with被处理,firstPer变量创建一个局部变量和变量添加到map自上下文,以便它是用于评估和其他上下文中声明的变量从开始,但只有包含< div >标记的范围内。

div th:with="firstPer=${persons[0]},secondPer=${persons[1]}">

  <p>

    The name of the first person is <span th:text="${firstPer.name}">Julius Caesar</span>.

  </p>

  <p>

    But the name of the second person is 

    <span th:text="${secondPer.name}">Marcus Antonius</span>.

  </p>

</div>

th:width属性允许重用变量定义在相同的属性:

<div th:with="company=${user.company + ' Co.'},account=${accounts[company]}">...</div>
