thymeleaf中的th:with用法

局部變量,th:with能定義局部變量:

<div th:with="firstPer=${persons[0]}">
  <p>
    The name of the first person is <span th:text="${firstPer.name}">Julius Caesar</span>.
  </p>
</div>

當th:with被處理,firstPer變量創建一個局部變量和變量添加到map自上下文,以便它是用於評估和其他上下文中聲明的變量從開始,但只有包含< div >標記的范圍內。

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屬性允許重用變量定義在相同的屬性:

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