thymeleaf提供了几种判断，if、switch
- 后台数据
public class TestVo {
private String name;
private Integer Score;
private Integer male;
private Date birthday;
public TestVo(String name, Integer score, Date birthday, Integer male) {
this.name = name;
Score = score;
this.male = male;
this.birthday = birthday;
}@RequestMapping("/test01")
public String thymeleaf(ModelMap map){
List<TestVo> testVos=new ArrayList<>();
testVos.add(new TestVo("数学",10,new Date(),1));
testVos.add(new TestVo("数学0001",70,new Date(),2));
testVos.add(new TestVo("数学01",100,new Date(),3));
map.put("test",testVos);
return "/back/import/test";
}- 前端语法
<table>
<thead>
<th></th>
</thead>
<tbody>
<tr th:each="test:${test}">
<!--判断成绩-->
<td th:if="${} gt 0 and ${} lt 60">差</td>
<td th:if="${} ge 60 and ${} le 70">中</td>
<td th:if="${} gt 70 and ${} le 80">良</td>
<td th:if="${} gt 80 and ${} le 90">优</td>
<td th:if="${} gt 90 and ${} le 100">超级优秀</td>
</tr>
<br>
<tr th:each="test:${test}">
<!--判断成绩 一般只有两种情况的时候可以使用这种方式-->
<td th:if="${} gt 0 and ${} lt 60">差</td>
<!--除了这些条件之外的-->
<td th:unless="${} gt 0 and ${} lt 60">及格</td>
</tr>
<tr th:each="test:${test}">
<td th:switch="${}">
<span th:case="1">男</span>
<span th:case="2">女</span>
<!--其他情况-->
<span th:case="*">未知</span>
</td>
</tr>
</tbody>
</table>- 结果
差
中
超级优秀
差
及格
及格
男
女
模板操作
主要引入公共头部和底部相关代码使用 ，当然也可以其他地方使用
- 示例
底部模板代码
<!DOCTYPE html>
<html lang="en" xmlns:th="http:///1999/xhtml">
<body>
<div th:fragment="footer">
© 2016 xxx
</div>
</body>
</html>Springboot整合引入模块
<!--写入绝对路径即可引入 -->
<div th:include="/back/import/footer :: footer"></div>文本和带格式文本
用来输入内容到标签内部，而不是attr中。分为th:text和th:utext两种，后者可以渲染文本中的标签。
- th:utext
("msgutext","<b>1111</b>");<div th:utext="${msgutext}"></div>
结果：被渲染了
- th:text
<div th:text="${msgutext}"></div>
结果:原样输出到页面。
外围包裹–block
有时候需要在代码外部加层条件，但写div之类的又影响样式，此情况下你可以用下面这种方式:
<th:block th:with="score=${}">
<td th:if="${score} ge 60">及格啦</td>
</th:block>循环
遍历元素
- 示例：
<tr th:each="test:${test}">
<td th:text="${}"></td>
</tr>循环下标判断
List<String> list=new ArrayList<String>();
("1s");
("2s");
("3s");
("list",list);<th:block th:each="mylist,iterStat:${list}">
111
<span th:text="${mylist}"></span>
<th:block th:if="${ le 1}">
<span th:text="${mylist}"></span>
</th:block>
</th:block>常用操作
- 日期格式化
<td th:text="${#(,'yyyy-MM-dd HH:mm:ss')}" ></td>- 字符截取长度
<td th:if="${#() gt 5 } " th:text="${#(,0,5) + '…'}"></td>- 下拉选择
<select name="subId" id="subId" lay-verify="" >
<option value="">请选择</option>
<option th:each="channelsub:${subchannels}" th:selected="${ == subId}" th:value="${}" th:text="${}"></option>
</select>js取值
有时候需要传递参数到js中，按如下方式：
<script th:inline="javascript" >
var size= [[${()}]];
(size)
</script>- 进阶
ps: 下面涉及到thymeleaf的语法出，可以替换成其他thymeleaf的语法来用
<script th:inline="javascript" >
//尺寸等于3时打印日志..
/*[# th:if="${() eq 3}"]*/
('Welcome admin');
/*[/]*/
</script>css取值
首先需要后台设置classname、align的值，之后按如下方式：
<style th:inline="css">
.[[${classname}]] {
text-align: [[${align}]];
}
</style>结语
thymeleaf还有很多其他的语法，这里只是做个入门，方便上手，详细教程请参阅 官方教程。当然也可以加群交流。
