【问题标题】:How to know the selected datatable rows before form submit如何在表单提交之前知道选定的数据表行
【发布时间】:2022-01-13 21:40:33
【问题描述】:
我有以下数据表:LIVE DATATABLES
在单击按钮提交表单之前,我想知道所选行的 ID。
我尝试过的:
$( "#testrow" ).click(function() {
console.log(DT4.rows().ids());
});
我使用了rows().ids() 方法(official datatables api documentation)
我希望得到一个数组或与所选行的索引号类似的东西,但我得到的是:
此方法不会读取 tr 的 DOM id,所以我想知道在提交表单之前哪种方法是了解(从 DOM 中)选择了哪一行的最佳方法。

【解决方案1】:
你可以这样试试:
$(document).ready(function() {
var table = $('#example').DataTable();
$('#example tbody').on( 'click', 'tr', function () {
$(this).toggleClass('selected');
} );
$('#button').click( function () {
let data = table.rows('.selected').data()
console.log(data)
} );
});
