Basicly I am trying to fill some boxes in a form and then press send to fill a form quickly. I thought the best way was to go to console in the browser and type a command like this;

//fill the value
document.getElementsByClassName("form-control").item("1").value=11111;
document.getElementsByClassName("form-control").item("2").value=22222;

//press the button
document.getElementsByClassName("btn btn-success mr-2").item("0").click();

But for some reason although I can see that the value changes the from doesn't think it has been edited. When I try to submit it, it submits as empty.
