Question

我有一个带有复选框插件的服务器端数据表设置。每个复选框都有一个product_id的数据。

var table = $('#display_users').DataTable( {
        "processing": true,
        "serverSide": true,
        'ajax': '{{ route ('/getUsers') }}',
        'columns' : [
            {"data" : "product_id"},
            {"data" : "product_id"},
            {"data" : "first_name"},
            {"data" : "last_name"},
            {"data" : "email"},
            {"data" : "company"},
            {"data" : "department"},
            {"data" : "created_at"}
        ],
        'columnDefs': [
            {
                'targets': 0,
                'checkboxes': {
                    'selectRow': true
                },

我希望能够在选中一个复选框后，选中所有具有相同product_id的复选框。这仅对于当前所选页面上的记录是必需的。似乎可以通过选择api复选框来实现，但是到目前为止我还没有成功

我认为'checkbox'插件没有太大价值，因为它的功能可以通过几行代码轻松实现，同时还可以提供更大的灵活性。

但是，由于您所需的功能可以通过本机DataTables API轻松编码，因此您实际上并不需要深入研究“复选框”插件内部。

//listen for the clicking first column checkboxes
$('#display_users').click('tbody td:eq(0) [type="checkbox"]', function(){
  //grab current checkbox state and criteria to match (product_id) from the row data
  const state = $(event.target).prop('checked');
  const productId = dataTable.row($(event.target).closest('tr')).data().product_id;
  //iterate through current page rows and adjust checkboxes upon matching product_id
  dataTable.rows({page:'current'}).every(function(){
    if(this.data().product_id == productId) $(this.node()).find('td:eq(0) [type="checkbox"]').prop('checked', state);
  });
});

//data sample
const srcData = [
  {product_id: 7, first_name: 'Nick', last_name: 'Furry', company: 'Avengers Inc'},
  {product_id: 7, first_name: 'Steve', last_name: 'Rogers', company: 'Avengers Inc'},
  {product_id: 4, first_name: 'Arthur', last_name: 'Curry', company: 'Justice Ltd'},
  {product_id: 4, first_name: 'Clark', last_name: 'Kent', company: 'Justice Ltd'},
  {product_id: 4, first_name: 'Barry', last_name: 'Allen', company: 'Justice Ltd'}
];

//datatable initialization
const dataTable = $('#display_users').DataTable({
  dom: 't',
  order: [1, 'asc'],
  data: srcData,
  columns: [null, ...Object.keys(srcData[0])].map(header => ({title: header || '', data: header})),
  columnDefs: [
    {targets: 0, orderable: false, render: () => '<input type="checkbox"></input>'}
  ]
});

//essential part - row checkbox click hander
$('#display_users').click('tbody td:eq(0) [type="checkbox"]', function(){
  //grab current checkbox state and criteria to match (product_id)
  const state = $(event.target).prop('checked');
  const productId = dataTable.row($(event.target).closest('tr')).data().product_id;
  //iterate through current page rows and adjust checkboxes upon matching product_id
  dataTable.rows({page:'current'}).every(function(){
    if(this.data().product_id == productId) $(this.node()).find('td:eq(0) [type="checkbox"]').prop('checked', state);
  });
});
