Chrome 没有获取表单变量

Question

I have a form that feeds variables into a piece of javascript for building a graph. When running the page in chrome the submit button just reloads the page and the variable data from the form isn't gathered and fed into the javacript. Below is the snippet of code for the form and part of the javascript that picks up the variables and uses them in the URL.

This works perfectly in Firefox without a single error in sight. Chrome just refuses to pick up the input from the form. Unfortunately the console hasn't picked up any errors either. I've tried using POST, but this doesn't resolve the issue, GET works anyhow when I run the PHP page with the variables included without issue. I've done all I can to make the form as technically right as I can. I'm out of ideas. Changing the submit button doesn't resolve the issue either.

<form name="forminput" id="forminput">
<label for="accountname">Account Name :</label>
<input type="text" id="accountname" name="accountname">
<br>
<label for="startpopupDatepicker">Start Date : </label>
<input type="text" id="startpopupDatepicker" name="startpopupDatepicker">
<label for="endpopupDatepicker">End Date : </label>
<input type="text" id="endpopupDatepicker" name="endpopupDatepicker">
<br>
Node : <select id="nodename" name="nodename">
    <option value="EU">EU</option>
    <option value="US">US</option>
    <option value="APAC">APAC</option> </select>
<input type="button" value="Submit" name="Submit" onclick="history.go()">
</form>

<script>
//Input Start

var account = document.getElementById("accountname").value;
var node = document.getElementById('nodename').value;
var calstartdate = document.getElementById('startpopupDatepicker').value;
var calenddate = document.getElementById('endpopupDatepicker').value;

//Input End
//Chart Beginning

var chart = c3.generate({
bindto: '#chart',
data: {
    x : 'date',
    url: 'sqlcallcounts2.php?account='+account+'&node='+node+'&startdate='+calstartdate+'&enddate='+calenddate,
},

I resolved this by making the whole of the Javascript that's in the page a function. I then used the onClick of the Submit button to active the function. It now works perfectly.
