在加载jQuery DataTable时,我有以下代码。如何将其他参数传递给AJAX调用?以下问题和解答中建议的fnServerParams回调不起作用。也就是说,天真地使用 aodata.push()会导致 push is undefined(因为实际上aodata不是数组)。那么正确的方法是什么?
When loading a jQuery DataTable, I have the code shown below. How do I pass additional parameters to the AJAX call? The fnServerParams callback suggested in the questions and answers below does not work. That is, naively using aodata.push() results in "push is undefined" (because, indeed, aodata is not an array). So what's the correct way to do this?

代码:
self.dataTable = self.dataTableContainer.DataTable({ "autoWidth": false, "bSort": false, "displayStart": 0, "paging": false, "lengthChange": false, "processing": true, "serverSide": true, "dom": "<'dataTables_header dashboard_alert_history__alertHeader'i>", "ajax": { url: getDataUri, error: onError, cache: false, "fnDrawCallback": onTableDrawn, }, "fnDrawCallback": onTableDrawn, "language": { "info": resources.alarmHistory, "infoEmpty": resources.alarmHistory, "infoFiltered": '' }, "columns": [ { "data": "timestamp", "mRender": function (data) { return IoTApp.Helpers.Dates.localizeDate(data, 'L LTS'); }, "name": "timestamp" }, { "data": "deviceId", "mRender": function (data) { return htmlEncode(data); }, "name": "deviceId" }, { "data": "ruleOutput", "mRender": function (data) { return htmlEncode(data); }, "name": "ruleOutput" }, { "data": "value", "mRender": function (data) { return htmlEncode(IoTApp.Helpers.Numbers.localizeFromInvariant(data)); }, "name": "value" }, ], "columnDefs": [ { "targets": [0, 1, 2, 3], "className": 'table_alertHistory_issueType', "width": "20%" } ], });推荐答案
我忽略了RTFM。对于版本1.9和更高版本, fnServerParams 回调现在旧版较早。在最新版本的DataTables中,您可以使用DataTables文档中所述的ajax数据参数 。在下面的示例中,将 mykey 附加到 d 对象将达到目的:
I neglected to RTFM. The fnServerParams callback is now legacy for versions 1.9 and earlier. In the latest version of DataTables, you leverage the ajax data parameter as described in the DataTables documentation. In the example below, appending mykey to the d object will do the trick:
$(document).ready(function() { $('#example').DataTable( { "processing": true, "serverSide": true, "ajax": { "url": "scripts/server_processing.php", "data": function ( d ) { d.myKey = "myValue"; // d.custom = $('#myInput').val(); // etc } } } ); } );更多推荐
