Question : How to send a POST value with javascript onKeyPress

Hi experts.

I have a booking calendar navigation done using submit buttons which send a post value. Now I'd like to be able to control this navigation using the keyboard arrow keys (left for last day/week and right for next day/week). How could this be done?

I found something like this which sends a form on key press

<script language="JavaScript">
      function submitonEnter(evt) {
            var charCode = (evt.which) ? evt.which : event.keyCode
            if(charCode == "39"){
                  document.dprev.submit();
            }
      }
</script>';

But I believe the problem here is that I cannot just send the right form, since in php I'm checking which submit button within a single form was being submitted. So instead of just submitting a right form I believe I need to send the post value directly using Javascript.

The simple HTML looks something like this:

<form action="#" method="post">
      <input class="prev" name="dprev" value="&nbsp;" type="submit"  />
      <input class="next" name="dnext" value="&nbsp;" type="submit"  />
</form>

Thank you in advance.

To not to make controls transparent but only the form, use TransparencyKey  property like:

public Form2()
        {
            InitializeComponent();

            //this.Opacity = 0.5;

            this.TransparencyKey = BackColor;
        }
