Common labels and grammar analysis in Thymeleaf

Thymeleaf is a template engine used to build a Java -based web application.It has strong processing capabilities and can generate dynamic HTML pages by embed the Thymeleaf tag and grammar in the template. The following is the label and grammar analysis commonly used in Thymeleaf: 1. Expressive grammar: Thymeleaf uses attribute reference expressions to access model data.The expression of the `$ {}` package can access the model data in the template, such as `$ {user.name}` can get the "name" property in the model called "user". 2. Text output: Use Thymeleaf's `Th: Text` property to output the data into the template.For example, use the `Th: Text =" $ {user.name} "` `` Th: Text = "$ {user.name}" `" 3. iteration cycle: Thymeleaf provides `Th: Each` tag for iterative cycle.Use the `Th: EACH` tag to traverse the collection or array, and apply each element to the specified template plate. <ul> <li th:each="user : ${users}" th:text="${user.name}"></li> </ul> 4. Condition judgment: Thymeleaf's `Th: if` and` Th: UNLESS` tags can be used for conditional judgment.`Th: if` label determines whether the template is displayed according to the results of the condition, and the` th: unless` tag is opposite to the `Th: if`. <div th:if="${isAdmin}"> <p>Welcome Admin!</p> </div> 5. URL link: Use Thymeleaf's `Th: HREF` Properties to generate a dynamic URL link.For example, the `th: href ="@{/users/id} (id = $ {user.id})} "" "Url link for user details. 6. Form processing: Thymeleaf provides a convenient form processing function.Use the `Th: Object` property to bind the form to the model object, and use the` Th: Field` attribute to bind the field section of the form to the model attribute. <form th:object="${user}" th:action="@{/save}" method="post"> <input type="text" th:field="*{name}" /> <input type="text" th:field="*{email}" /> <button type="submit">Save</button> </form> These are just examples of labels and grammar commonly used in Thymeleaf.Thymeleaf also has more functions and grammar that can be used to build dynamic web applications.I hope this article will help you understand the common labels and grammar of Thymeleaf!
