More a comment than an answer - but I cannot add comments yet: Thanks for your help, the count was the easy part. Just for others that might come here. I hope that it will save you some time.
更多的是评论而不是答案 - 但我还不能添加评论：感谢您的帮助，计数是最简单的部分。只为其他可能来这里的人。我希望它能为你节省一些时间。
It took me a while to get the attributesfrom the rows and to understand how to access them from the data()Object (that the data() is an Array and the Attributes can be read by adding them with a dot and not with brackets:
我花了一些时间从行中获取属性并了解如何从data()对象访问它们（data() 是一个数组，可以通过添加点而不是括号来读取属性：
$('#button').click( function () {
for (var i = 0; i < table.rows('.selected').data().length; i++) {
console.log( table.rows('.selected').data()[i].attributeNameFromYourself);
}
} );
(by the way: I get the data for my table using AJAX and JSON)
（顺便说一句：我使用 AJAX 和 JSON 获取我的表的数据）

var table = $('#myTableId').DataTable();
var a= [];
$.each(table.rows('.myClassName').data(), function() {
a.push(this["productId"]);
});
console.log(a[0]);
