[Solved] Check if a date has been selected. Bootstrap input type date


As mentioned in comment, you should write

var selectedDate = $("#date").val();
if(selectedDate == "") {  // use == instead of = here. It will check condition
  alert("date is not selected");
}else{
  alert(selectedDate);
}

Note:- single = is an assignment operator. It assigns the value to variable. While == checks the condition. You can also write if(selectedDate) to check date is selected or not.
