thymeleaf th:if 判断字段是否存在

1. 判断字段是否存在（后台是否返回该字段）

th:if=”${data.containsKey(‘details’)}”

<table class="layui-table" th:if="${data.containsKey('details')}">
    <thead>
        <tr>
            <th>序号</th>
            <th>检验项目</th>
            <th>检验结果</th>
        </tr>
    </thead>
    <tr th:each="checkRecordResult,infoStat : ${data.details}">
        <td>[[${infoStat.index + 1}]]</td>
        <td>[[${checkRecordResult.result_name}]]</td>
        <td>[[${checkRecordResult.result_value}]]</td>
    </tr>
</table>

2. 判断字段是否为null

th:if=”${data.details!=null}”
