如果选中 thymeleaf 中的复选框，如何更改 boolean 值？
[英]How to change boolean value if checked with checkbox in thymeleaf?
问题描述
I'm building weekly availability when a new user is registering.
当新用户注册时，我正在建立每周可用性。 I'm using checkboxes to see what part of the day the user is available.我正在使用复选框来查看用户在一天中的哪个部分可用。 For example if user is available on Monday until evening then user checks morning and evening under Monday.例如，如果用户在星期一到晚上都有空，那么用户在星期一之前检查早上和晚上。
th:field="${schedule.morning}" gives me and error. th:field="${schedule.morning}" 给了我和错误。 th:name="${schedule.morning}" doesn't change the boolean value. th:name="${schedule.morning}" 不会更改 boolean 值。
Schedule model时间表 model
@NotNull
@NotEmpty(message = "Day of the availability is required.")
private String day;
@NonNull
@Column(nullable = false)
private boolean morning;
@NonNull
@Column(nullable = false)
private boolean afternoon;

@Column(nullable = false)

According to the official thymeleaf documentation根据官方 thymeleaf 文档
http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#fixed-value-boolean-attributes http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#fixed-value-boolean-attributes
`th:checked is considered as a fixed-value Boolean attribute. `th:checked 被视为固定值 Boolean 属性。 So try like bellow.所以尝试如下。
<input type="checkbox" class="custom-control-input" th:checked="${schedule.morning}" th:id="|morning-${schedule.day}|" />
