thymeleaf公共页面元素抽取

thymeleaf公共页面元素抽取

1、抽取公共片段
<div th:fragment="copy">
&copy; 2011 The Good Thymes Virtual Grocery
</div>

2、引入公共片段
<div th:insert="~{footer :: copy}"></div>
~{templatename::selector}:模板名::选择器
~{templatename::fragmentname}:模板名::片段名

3、默认效果:
insert的公共片段在div标签中
如果使用th:insert等属性进行引入,可以不用写~{}:
行内写法可以加上:[[~{}]];[(~{})];

三种引入公共片段的th属性:

th:insert:将公共片段整个插入到声明引入的元素中

th:replace:将声明引入的元素替换为公共片段

th:include:将被引入的片段的内容包含进这个标签中

<footer th:fragment="copy">
&copy; 2011 The Good Thymes Virtual Grocery
</footer>

引入方式
<div th:insert="footer :: copy"></div>
<div th:replace="footer :: copy"></div>
<div th:include="footer :: copy"></div>

效果
<div>
    <footer>
    &copy; 2011 The Good Thymes Virtual Grocery
    </footer>
</div>

<footer>
&copy; 2011 The Good Thymes Virtual Grocery
</footer>

<div>
&copy; 2011 The Good Thymes Virtual Grocery
</div>

引入片段的时候传入参数:

<nav class="col-md-2 d-none d-md-block bg-light sidebar" id="sidebar">
    <div class="sidebar-sticky">
        <ul class="nav flex-column">
            <li class="nav-item">
                <a class="nav-link active"
                   th:class="${activeUri=='main.html'?'nav-link active':'nav-link'}"
                   href="#" th:href="@{/main.html}">
                    <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="feather feather-home">
                        <path d="M3 9l9-7 9 7v11a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2z"></path>
                        <polyline points="9 22 9 12 15 12 15 22"></polyline>
                    </svg>
                    Dashboard <span class="sr-only">(current)</span>
                </a>
            </li>

<!--引入侧边栏;传入参数-->
<div th:replace="commons/bar::#sidebar(activeUri='emps')"></div>
