Thymeleaf引导程序模式创建不起作用

Question

这是我与百里香的春季靴子项目。控制器会将价格表返回给html。我使用th:attrappend索引为标签<i>提供了一个ID。 使用thymeleaf foreach priceList并创建引导程序模态。 thymeleaf确实创建了模态，但是当我单击标签<i>“ +”时，模态不显示。

<table id="mytable" class="table table-bordred table-striped">
    <thead>

    <th>a</th>
    <th>b</th>
    <th>c</th>

    </thead>

    <tbody>

    <tr th:each="priceData, each_index: ${priceList}">
        <td th:text="${priceData.priceid}"></td>
        <td th:text="${priceData.iscorrect}"></td>
        <td th:text="${priceData.message}"></td>
        <td data-toggle="modal"
            th:attrappend="data-target='#' + ${each_index.index}"><i class="">+</i>
        </td>
    </tr>

    </tbody>
</table>
<div th:each="priceData, each_index : ${priceList}" class="modal fade" th:attrappend="id=${each_index.index}" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span>
                </button>
                <h4 class="modal-title" id="myModalLabel">Modal title</h4>
            </div>
            <div class="modal-body">
                ...
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>
