在Datatable中单击选择行并将所选数据导出为Excel

我正在使用数据表向其中填充数据。要求是要导出这些数据。用户可以一次导出“选定的行”或“全部”数据。我已经使用了数据表导出Excel功能，该功能创建按钮两个“导出全部”按钮和“导出选择”，导出数据。导出所有工作正常，但是当我使用datatable的功能来选择使用“select：true”的行时，我必须使用CTRL按钮来选择多行，并且它工作正常并导出数据，但我不希望这，所以我在table.tr上创建了一个click事件，它将选中的类添加到TR中，TR选择该行，但是在选择该行后，当我导出数据时，没有任何导出，则该excel为空。可能是什么问题，“select：true”会将选中的类添加到TR中，并且我还将添加的类添加到TR上，但是为什么数据不会导出，任何人都可以对此有所了解。我还创建了一个小提琴：Datatable Fiddle 我的代码：在Datatable中单击选择行并将所选数据导出为Excel

你测试的类实际上得到正确的元素上设置（和它必须工作方式）？如果我正确理解jquery和js，$（this）可能不是您所期望的... – Jakumi

@Jakumi是的，课程已添加到TR中，我已经检查过它。你能告诉我这里有什么错误吗？（这个） – Mukesh
