Hi guys i have one js function in that i have one array which will get the depotidowner id's it will be like 1,2,4,5,6

So what i am trying is i would like to check the condition like if all the values in array is same then return that value if not return false;

Here is my array:

function createOrderForTicket()

{

    var selectedVehicles = ;

    var selectedVehiclesDepotIds = ;

    $('#vehicleListForNewOrder input:checked').each(function() {

        selectedVehicles.push($(this).val());

        selectedVehiclesDepotIds.attr('depotIdOwner');

    });



    if (0 === selectedVehicles.length) {

        $('#vehicleListForNewOrderError').show();

        $('#vehicleListForNewOrderError').addClass('error');



        return false;

    }



    if (0 === selectedVehiclesDepotIds.length) {

        return false;

    }







    var vehicleIds = selectedVehicles.join(',');

    var contactId = $('#contactId').val();

    var personId = $('#personId').val();

    var ticketId = $('#ticketId').val();

    var depotIdOwner = selectedVehiclesDepotIds.val();

    var url = vbdBaseUrl + '/order/customer/index/contactId/' + contactId + 

        '/personId/' + personId + '/ticketId/' + ticketId + '/vehicleId/' + vehicleIds + '/id/';



    if (depotIdOwner) {

        url = url + '/depotId/' + depotIdOwner;

    }



    window.open(url, '_blank');

    location.reload();

}

Here is one approach to how you might do this. A Set in javascript can only hold unique values, thus, if its size equates to 1, then the array has all equal values, if its size equates to something greater than one, then all the values are not unique:

Take a look at the snippet below:

const aArr = [1, 2, 3, 4, 5];

const bArr = [1, 1, 1, 1, 1];



const isUniqueArr = arr => {

  const tmp = new Set(arr);

  if(tmp.size > 1) {

    return false;

  }

  return arr[0];

}



console.log(isUniqueArr(aArr)); // expected: false



console.log(isUniqueArr(bArr)); // expected: 1

For your example you can use this function like so:

let res = isUniqueArr(selectedVehiclesDepotIds);

To get the result, where res is either false or the number which appears across the entire array.

This function can be applied to your code like so:

function checkIfAllTheSelectedVehiclesDepotIdsSame(selectedVehiclesDepotIds) 

{ 

  var tmp = new Set(selectedVehiclesDepotIds); 

  if(tmp.size > 1) { 

    return false; 

  } 

  return arr[0]; 

}





var res = checkIfAllTheSelectedVehiclesDepotIdsSame(selectedVehiclesDepotIds) 

if(res == false) { 

  // logged in depot id 

} else { 

  // store the value held in res 

}

// Your createOrderForTicket() goes under here

Then in your createOrderForTicket() function you can do the following:

var res = checkIfAllTheSelectedVehiclesDepotIdsSame(selectedVehiclesDepotIds) 

if(res == false) { 

  // logged in depot id 

} else { 

  // store the value held in res 

}

The following code Should work for you. Fill free to ask any questions you might have.

var arrayTocheck1 = [1,2,3,4];

var arrayTocheck2 = [1,1,1,1];



function checkIfAllTheSame(arr){

    var i = 0;

    var allTheSame = false;

    if(arr && arr.length > 0){

        allTheSame = true;

        var firstElement = arr[0];

        for(i=1; i<arr.length; i++){

            if(arr[i] !== firstElement){

                allTheSame=false;

                i=arr.length;

            }

        }      

    }

    return allTheSame;

}



function getCommon(arr){

    if(checkIfAllTheSame(arr)){

        return arr[0];

    }

    return null;

}



alert(getCommon(arrayTocheck1));

alert(getCommon(arrayTocheck2));
