how to pass html form data to variable (nodejs / javascript)

so i'm using nodejs and nodejsdb-mysql. i want to make form for adding and searching posts. I make html page with form, transform it to node using jsdom but how do i set up variables? for example my html form is like:

name = text input surname = text input submit

and how do i pass inserted name/surname to var??

You will need to turn your submit into a button with an event such as onclick - this might be what you are looking for:

<input type="button" value="Submit" id="submit" name="submit" onclick="submit()">

<script type="text/javascript">
function submit(){
var name = document.getElementById('**name**').value;
var surname = document.getElementById('**surname**').value;
alert("Thanks for submitting, " +name);
}
</script>

With nodejsdb-mysql sooner or later you will face real problems like date localization problems and so on, use https://github.com/felixge/node-mysql instead
