将值从表传递到模式对话框

Question

我正在尝试将值从表传递到模态窗口，但我没有得到它

我从jQuery尝试了一些东西，但我不知道我可能做错了什么。我将发布代码，这是有效的，但我在尝试中没有做出任何改变。

单击更改时，我想获取值并移至对话框。

<c:if test="${fn:length(lista) > 0 }">
    <table class="table table-hover">
        <tr>

            <th >Código</th>
            <th>Nome</th>
            <th>Descrição</th>
            <th>Medida</th>
            <th>Fornecedor</th>
            <th>Quantidade Mínima</th>
            <th>Quantidade Máxima</th>
            <th>Estoque</th>
            <th>Categoria</th>
            <th>Preço</th>
            <th></th>
        </tr>
        <c:forEach items="${lista }" var="mat">
            <tr>

                <td>${mat.codigo }</td>
                <td>${mat.nome }</td>
                <td>${mat.descricao }</td>
                <td>${mat.medida }</td>
                <td>${mat.fornecedor }</td>
                <td>${mat.qtd_Min }</td>
                <td>${mat.qtd_Max }</td>
                <td>${mat.estoque }</td>
                <td>${mat.categoria.categoria }</td>
                <td>${mat.preco }</td>

                <td><a href="#DialogAlterarMaterial" class="btn btn-xs btn-info" data-toggle="modal">Alterar</a> 
                    <a href="remover.html?id_material=${mat.id_material }"class="btn btn-xs btn-danger" >Remover</a>
                </td>
            </tr>
        </c:forEach>
    </table>

</c:if>

    aria-hidden="true" aria-labelledby="myModalLabel" role="dialog"
    tabindex="-1" style="display: none;">

Answer 1

您可以在<a href="#DialogAlterarMaterial" class="btn btn-xs btn-info" data-toggle="modal">Alterar</a>上添加点击事件处理程序。

单击“Alterar”按钮时，使用jquery在td s中查找数据，然后将数据设置为模态对话框。

摘要供参考：

var $tds = $(this).parent().siblings();
var codigo = $tds.eq(0).html();
