GetType() in Javascript

Question

how do i achieve this c# code in javascript

protected void Validate(object sender, EventArgs e)
{
    var _typeName = sender.GetType().FullName;
}

i want to add the Validate in all RadControls (telerik) and i wanna check if the sender is type of RadDatePicker

i tried this but its not working so i wanna check if what is the type name of the sender.

if (Telerik.Web.UI.RadDatePicker.isInstanceOfType(sender)) 
{
    alert("it is a datepicker");
}

i think this is what you need

var toType = function(obj) {
  return ({}).toString.call(obj).match(/\s([a-zA-Z]+)/)[1].toLowerCase()
}

.......

var theTypeIs = toType("Bresleveloper");

result will be "string"

it just returns an "object" – Vincent Dagpin Oct 20 '13 at 10:34
run this code : var toType = function(obj) { return ({}).toString.call(obj).match(/\s([a-zA-Z]+)/)[1].toLowerCase() } toType("Bresleveloper") – bresleveloper Oct 20 '13 at 14:38

Try using the type

type(sender); //will return you the type of control you are using

throws "type is not defined". Where would you get "type" from? – Jacques Mar 31 '21 at 12:27
