Save the Text in a Text Field as a Variable

Flutter : how do i save input from a text field to an int variable?

you should not write this line transactions.add(s); in onChanged method, because in this way in each number you enter you add a value to the list.
so you have to assign onChanged value to amount value and add a button to your dialog in button's onPressed method add this line transactions.add(s);

Save text field to a variable using jQuery, showing undefined

this needs to be INSIDE your click handler so that you grab the value when you click. The way you have it, the val gets set on page load -- which is likely undefined at that point.

var modelNumber = $('#modelBox').val();

$('#submit').click(function findManufacturer(){
    var modelNumber = $('#modelBox').val();
    var firstFour = modelNumber.substring(0,4);
    if (firstFour.includes("B")){
      manufacturer = "AU Optronics";
     $('#answer').after("AU Optronics");
   }else{
     $('#answer').after("No Manufacturer found");
    }
  });
 });

EDIT: You can also place it outside of the click handler, so long as it is inside the docready, and the field never changes between page load and clicking the submit button.

How can i save a value in the textbox to a variable

You nearly had it already...

function dayscounter() {
    var travel = document.getElementById("doj").value;
    var days;
    for(days=1;days<=travel;days++)
    {
        document.write(days);
    }
}

The problem was, that your first assignment of the variable travel is made as soon as the HTML code is loaded. The user can't have made an input yet at that time, thus the variable stays empty. If you include document.getElementById("doj").value inside the function, you will get the value at that specific time you launch the function.
