html - submitting form through javascript and passing a variable with it - Stack Overflow

I want to submit a form and add a javascript variable with it. I tried using AJAX but that didn't work properly because the form is cut in two parts on the same page. I'm now using a <button onclick='submit_form()'>send</button> which calls on the following function:

function submit_form()
{
document.getElementById("form2").submit();
}

however I need to pass on a javascript variable current_score I have it declared and it has a value I just don't know how to add this to my submit function I tried using a return within the function itself and writing a function for it but neither worked :) help and hints are greatly appreciated. The idea is that people receive a score fill a form and send it to a database, The ajax script part was to try and pass the values on to the next page that will submit the data

• Is current_score a form value? If not, what is it? – wanovak Commented May 4, 2012 at 14:15
• I can't understand what you're asking. How did you "try using AJAX"? Do you have some sample code? – Marc Commented May 4, 2012 at 14:17
• it's a int variable that's used by another function to calculate a score. The idea is that people receive a score fill a form and send it to a database – Jeffrey Klinkhamer Commented May 4, 2012 at 14:19

Your question is not very clear. The simple way would be to append a get parameter to the URL you are requesting. The following example will append a hidden input element to your form:

var hidden = document.createElement("input");
hidden.type = "hidden";
hidden.name = "theName";
hidden.value = current_score;
var f = document.getElementById("form2");
f.appendChild(hidden);
f.submit();

You could store the information in window.variable also
