fragment介绍

fragment相似于JSP的tag，在html中文件中，能够将多个地方出现的元素块用fragment包起来使用。javascript

定义fragment

新建foot.html文件css

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:th="http://www.thymeleaf.org">
<footer th:fragment="footDiv">
    the content of footer
</footer>
</html>

fragment的引用

th:insert:保留本身的主标签，保留th:fragment的主标签。
th:replace:不要本身的主标签，保留th:fragment的主标签。
th:include:保留本身的主标签，不要th:fragment的主标签。（官方3.0后不推荐）

新建test.html文件html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:th="http://www.thymeleaf.org">
<!--导入片断-->
<div th:insert="footer :: footDiv"></div>
<div th:replace="footer :: footDiv"></div>
<div th:include="footer :: footDiv"></div>
</html>

获得的结果为java

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<!--导入片断-->
<div><footer>
    the content of footer
</footer></div>
<footer>
    the content of footer
</footer>
<div>
    the content of footer
</div>
</html

fragment的参数设置

定义：jquery

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:th="http://www.thymeleaf.org">
<div th:fragment="headDiv(showInfo)">
    the content of head!message:[(${showInfo})]
</div>
</html>

调用：bootstrap

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:th="http://www.thymeleaf.org">
<!--导入片断-->
<div th:include="head :: headDiv('测试')"></div>
</html>

结果：app

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<!--导入片断-->
<div>
    the content of head!message:测试
</div>
</html>

若是是多个参数的时候例子：测试

<div th:fragment="frag (onevar,twovar)">
    <p th:text="${onevar} + ' - ' + ${twovar}">...</p>
</div>

按参数定义时的顺序进行传递
<div th:replace="::frag (${value1},${value2})">...</div>
<div th:replace="::frag (onevar=${value1},twovar=${value2})">...</div>
能够不按照参数定义的顺序
<div th:replace="::frag (twovar=${value2},onevar=${value1})">...</div>

fragment的lexible layouts

定义：ui

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:th="http://www.thymeleaf.org">
<head th:fragment="head(title,links,scripts)">
    <title th:replace="${title}">The awesome application</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <link href="/static/css/test.css" rel="stylesheet">
    <script type="text/javascript" src="/static/js/jquery.js"></script>
    <th:block th:replace="${links}" />
    <th:block th:replace="${scripts}" />
</head>
</html>

使用：spa

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:th="http://www.thymeleaf.org">
<head th:include="head :: head(~{::title},~{::link},~{::script})">
    <title>html的title</title>
    <link rel="stylesheet" th:href="@{/css/bootstrap.css}">
    <script th:src="@{/js/bootstrap.js}"></script>
</head>
</html>

结果：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
    <title>html的title</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <link href="/static/css/test.css" rel="stylesheet">
    <script type="text/javascript" src="/static/js/jquery.js"></script>
    <link rel="stylesheet" href="/css/bootstrap.css">
    <script src="/js/bootstrap.js"></script>
</head>
</html>

注意是link 和script，不是links 和scripts
若是调用的页面没有link或者script ，则指定传入的参数为~{}便可。

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:th="http://www.thymeleaf.org">
<head th:include="head :: head(~{::title},~{::link},~{})">
    <title>html的title</title>
    <link rel="stylesheet" th:href="@{/css/bootstrap.css}">
</head>
</html>
