Question

我使用百里香叶3和我的除非块永远不会被执行

<th:block th:if="${products.productTypes gt 8 and products.productTypes lt 12}">
    <div th:replace="fragments/products/sub-granulates"/>
</th>
<th:unless="${products.productTypes gt 8 and products.productTypes lt 12}">
    <div th:replace="fragments/products/sub-traditional-products"/>
</th>

任何建议？

Answer 1

你的th：bloc没有关闭，除非，没有th：block

Answer 2

你的百里香是畸形的...应该是这样的：

<th:block th:if="${products.productTypes gt 8 and products.productTypes lt 12}">
    <div th:replace="fragments/products/sub-granulates"/>
</th:block>

<th:block th:unless="${products.productTypes gt 8 and products.productTypes lt 12}">
    <div th:replace="fragments/products/sub-traditional-products"/>
</th:block>

我相信自从thymeleaf 3以来，您还可以将代码简化为：

<div th:replace="${products.productTypes gt 8 and products.productTypes lt 12} ? ~{fragments/products/sub-traditional-products} : ~{fragments/products/sub-traditional-products}"/>

除非块从未执行过
