Idea of the following syntax used in this and other HTML document: |
|
|
|
|
|
|
|
|
|
|
|
<foo th:text="${#messages.msgOrNull('<key_from_messages.properties>')} ?: 'myThymeleafText'"> |
|
|
|
|
|
myHTMLPlainText |
|
|
|
|
|
</foo> |
|
|
|
|
|
|
|
|
|
|
|
-> A) In Thymeleaf, we check if a message key exists. In normal cases, a non-existent key is NOT null. |
|
|
|
|
|
Therefore, we use method msgorNull and enforce null value if the message key is not found. |
|
|
|
|
|
|
|
|
|
|
|
-> B) IF key is null: in section '?: myThymeleafText' we use text 'myThymeleafText' as a replacement |
|
|
|
|
|
value for the HTML tag string value. |
|
|
|
|
|
|
|
|
|
|
|
-> C) The last string value 'myHTMLPlainText' between tags is used if we open plain HTML file without |
|
|
|
|
|
Thymeleaf rendering. This is useful for offline viewing and for developers who want correct file |
|
|
|
|
|
rendering without Java overhead. |
