thymeleaf 學習筆記3

十、屬性優先順序

 十一、註釋

11.1  <!-- ... -->  同HTML/XML的註釋

<!-- User info follows -->
<div th:text="${...}">
...
</div>

11.2 thymeleaf解析器註釋 

thymeleaf解析的時候會被註釋，靜態打開時會顯示

單行   <!--/*  ...   */-->

<!--/* This code will be removed at thymeleaf parsing time! */-->

多行時：

<!--/*-->

...

...

<!--/*-->

<!--/*-->
    <div>
        you can see me only before thymeleaf processes me!
    </div>
<!--*/-->

11.3 靜態解析時被註釋，thymeleaf解析時會移除<!--/*/ 和 /*/-->標簽對，內容保留

<span>hello!</span>
<!--/*/
    <div th:text="${...}">
        ...
    </div>
/*/-->
<span>goodbye!</span>

這個註釋在寫th:block的時候很有用哦

<table>
    <!--/*/ <th:block th:each="user : ${users}"> /*/-->
    <tr>
        <td th:text="${user.login}">...</td>
        <td th:text="${user.name}">...</td>
    </tr>
    <tr>
        <td colspan="2" th:text="${user.address}">...</td>
    </tr>
    <!--/*/ </th:block> /*/-->
</table>

11.4 th:block 適用於比如說要迴圈兩個<tr>

it could be useful, for example, when creating iterated tables that require more than one <tr> for each element
