DataTable – 在jQuery中获取所有选定行的简便方法

我如何从jQuery DataTable （ https://datatables.net ）获取所有选定的行。

这里在stackoverflow中找到了计算所选行的方法，但是我需要将选定的行数据抛到下一个JavaServletPage来使用它。

我的DataTables代码配置：

            $(document).ready(function() { var lastBksId = null; var rowClass = "odd" var table = $('#table_view').DataTable({ scrollX: true, scrollY: '76vh', order: [[ 0, "desc" ]], scrollCollapse: true, paging: false, info: false, ordering: false, searching: false, fnRowCallback: function(row, data, index){ if (lastBksId == null){ lastBksId = data[0]; } if (lastBksId == data[0]){ row.className = rowClass; } else { if (rowClass == "odd"){ rowClass = "even"; } else {rowClass = "odd"; } row.className = rowClass; lastBksId = data[0]; } } }); $('#table_view tbody').on( 'click', 'tr', function () { $(this).toggleClass('selected'); } ); } );  

HTML – 表格：

  
 <% EntityManager em = Persistence.createEntityManagerFactory("man-jpa").createEntityManager(); int pageSize = 200; Class entyClass = NlHist.class; CriteriaBuilder builder = em.getCriteriaBuilder(); CriteriaQuery criteriaQuery = builder.createQuery(entyClass); Root from = criteriaQuery.from(NlHist.class); CriteriaQuery select = criteriaQuery.select(from); CriteriaQuery where = criteriaQuery.where(builder.isNotNull(from.get("pfcM"))); //CriteriaQuery having = criteriaQuery.having(builder.gt(builder.count(from.get("id")), 1)); TypedQuery typedQuery = em.createQuery(select); typedQuery.setFirstResult(0); typedQuery.setMaxResults(pageSize); List rows = typedQuery.getResultList(); // Getting Table Headers [...] %>

是一种在我的JS中编写函数的方法 – 配置 – 部分？

像这些：

 $('#...').on( ' ', ' ', function () {  } ); 

任何帮助，将不胜感激 ！

您可以迭代行数据

 $('#button').click(function () { var ids = $.map(table.rows('.selected').data(), function (item) { return item[0] }); console.log(ids) alert(table.rows('.selected').data().length + ' row(s) selected'); });
