Attach data to server-side request

[XDavidT]

I'm using Datatables server-side, and getting real-time data, I added custom date range search, and use ngModel to manage the data, but now I want to use it with all other column search.
Is there any option to attach the data with other request, and I will parse it in my server-side ?
Here is example: https://imgur.com/a/DrLmgB1
And this is how column serach work in my component:

ngAfterViewInit(): void {
    this.dtTrigger.next();
    //Enable search for each column and listen for change
    this.datatableElement.dtInstance.then((dtInstance: DataTables.Api) => {
      dtInstance.columns().every(function () {
        const that = this;
        $('input', this.footer()).on('keyup change', function () {
          let thisInput = this as HTMLInputElement;
          if (that.search() !== thisInput.value) {
            that
              .search(thisInput.value)
              .draw();
          }
        });
        $('select', this.footer()).on('keyup change', function () {
          let thisInput = this as HTMLInputElement;
          if (that.search() !== thisInput.value) {
            that
              .search(thisInput.value)
              .draw();
          }
        });
      });
    });
  }

One way to do it would be to hitch the columns to individual variables and bind them with ngModel. Later, in your Ajax call, add them as a property to dataTableParameters.

Example:

export class SomethingComponent {

// Step 1: Setup variables to all column inputs that user can toggle.

  searchDateField1 = new Date(); // or what have you
searchField2 = 'All' // you get the idea


// Step 2: Hitch the variables to AJAX call inside `dtOptions`

// inside init object
this.dtOptions = {
 // blah blah
ajax: (dataTableParameters, callback) =>{

  // here we go!
dataTableParameters.myData = {
 searchDateField1: this.searchDateField1,
searchField2: this.searchField2
};

// HTTP POST request
this.dataService.post(dataTableParameters). subscribe ();

})
};
}

Now in your server, it should be in req.body.myData. If not, just print req.body and find its exact path.
