I need to pass current view to ajax call in any ajax call and every time calendar grid changed

events: {
url: "{{route('clientSessionData')}}",
extraParams: {
    current_view_type: vm.type, // in here I want to pass current view now I stored it in vue element
},
    // our hypothetical feed requires UNIX timestamps
data: {
},
error: function() {
    $('#script-warning').show();
},
success: function(){
    console.log("successful: You can now do your stuff here. You dont need ajax. Full Calendar will do the ajax call OK? "); 
    // calendar.render();  
},
color: 'yellow',   // a non-ajax option
textColor: '#ffffff', // a non-ajax option,

},
