[Python知识库]Thymleaf循环List＜List＜Object＞＞取值

** Thymleaf循环根据下标取值**

1、后台代码

                        SeedNew seedNew = new SeedNew();
                        seedNew.setParentId(oneId);
                        List<SeedNew> seedNews = *****.selectSeedNewList(seedNew);
                        List<List<SeedNew>> newList = new ArrayList<>();
                        if (seedNews != null && !seedNews.isEmpty() && seedNews.size() > 0) {
                            int toIndex = 2;
                            for (int i = 0; i < seedNews.size(); i += 2) {
                                if (i + 2 > seedNews.size()) {
                                    toIndex = seedNews.size() - i;
                                }
                                List<SeedNew> li2 = seedNews.subList(i, i + toIndex);
                                ArrayList<SeedNew> arrayList = new ArrayList<SeedNew>();
                                arrayList.addAll(li2);
                                if(arrayList.size()==1){
                                    arrayList.add(new SeedNew());
                                }
                                newList.add(arrayList);
                            }
                        }
                       return newList;


    li2 ：是每两条一分为一组，在thymleaf循环时，直接取。

2、前端代码

th:each=“l ,inStat: ${newList}” ：l 不能是关键字，否则报错

                         <div class="box" th:each="l ,inStat: ${newList}">
                                <div class="box-max">
                                    <div class="box-lip">
                                        <img class="box-lip-img" th:src="@{${l.get(0)?.newPic}}"/>
                                        <div class="box-lip-tx">
                                            <p class="box-lip-p"><span th:text="${l.get(0)?.newName}"></span></p>
                                            <p class="box-lip-r" th:onclick="getNewValue([[${l.get(0).newId}]])">&gt;</p>
                                        </div>
                                    </div>
                                    <div class="box-lib">
                                        <img class="box-lip-img" th:src="@{${l.get(1)?.newPic}}"/>
                                        <div class="box-lip-tx">
                                            <p class="box-lip-p"><span th:text="${l.get(1)?.newName}"></span></p>
                                            <p class="box-lip-r" th:onclick="getNewValue([[${l.get(1).newId}]])">&gt;</p>
                                        </div>
                                    </div>
                                </div>
                            </div>
