How to change in view ajax according to requirement in drupal 8?

It's easy to handle this core changes of views. One thing we have to sure that Views Advanced feature "Use AJAX:" should be yes.

"Use AJAX: Yes"

After that we can check our views/ajax request by Inspect and Check with Network Tab. We are giving an example to easy to use this.

Example: Suppose we have to start any view/ajax request on click on any "id" in html then our code in jquery file will be:

jQuery(document).on("click", "#prodresources", function (e) {                
    var arr = base_fullurl.split('/');
    var page_nid = arr[2]; 
    Drupal.attachBehaviors();
    getInfo('application_resources',['block_3','block_13'], page_nid);    // we are creating a function on click on "prodresources" id.
});

Parameters:
view_name : "application_resources"       // that is view machine name
view_display_id : ['block_3','block_13']  // we can use multiple views block on same view.
view_args: page_nid                       // this is argument for view


We just have to pass these three parameters view_name:machine name and view_display_id: blocks in array in multiple case and last one is view_args: if arguments pass.

function getInfo(view_name, blocks, args) {
    var base_url = window.location.origin;       
    $.ajax({
      url: base_url+'/views/ajax',
      type: 'post',
      data: {
        view_name: view_name, 
        view_display_id: blocks,
        view_args: args,
      },
      dataTypeview_display_id: 'json',
      success: function (response) {
          if (response[3] !== undefined) {
          var viewHtml = response[3].data;
          $('#destination_id').html(viewHtml);
          Drupal.attachBehaviors();
        }           
      },
          error: function(data) {
           alert('An error occured!');
          }
    });
}
