<input id="submit" type="hidden" value="Reverse Geocode" autofocus> 

Answer 1

You can do as following:

<script type="text/javascript">
document.getElementById("submit").click();
</script>

Answer 2

At first, your button is not a button. It's aa hidden field.

In order to make it a button, change type="hidden" to type="button" . To make it invisible to the user, you could use inline styles like this: style="display: none;" .

As a result, your button looks like this: <input id="submit" style="display: none" type="button" value="Reverse Geocode">

Now, to click it, simply call the click() method:

document.getElementById('submit').click();

May be you can do the following:

 document.getElementById('chkTest').addEventListener('click', function(){ if(this.checked) document.getElementById('submit').click(); }); document.getElementById('submit').addEventListener('click', function(){ alert('button clicked'); }); 

 <input id="submit" type="hidden" value="Reverse Geocode" autofocus /> <input type="checkbox" id="chkTest" /> Check To Click The Button
