Submit form with parameter through Javascript

Question

Below is my Javascript code where k and m are Javascript variables.

function javascriptfunction() {
  document.forms[formname].action="gotopage.php?parameter1="+k+"&parameter2="+m;
  document.forms[formname].submit();
}

The above code executes correctly when my HTML form has a POST method. Below is my HTML page:

<form name="formname" action=# method=POST>
  <input type=text name="data1" value="one">
  <input type=text name="data1" value="two">
  <input type=button name="button1" value="send" onclick="javascritfunction();">
</form>

But when I give a GET method in my HTML form, then the HTML form data is submitted i.e

gotopage.php?data1=one&data2=two is submitting not Javascript action value i.e
gotopage.php?parameter1="+k+"&parameter2="+m

So how to submit the form with Javascript parameter when the method is GET in the HTML form?

Answer 1

Submitting a GET form will replace the query string in the action with the form data.

Put the data in hidden inputs instead.
