  • what you want? If user clicked the check box button should be clicked?? – Siva Ganesh Commented May 18, 2018 at 5:09
  • you can just call the click event of the button window.load() or if you have a function assigned to it just call it. – vikscool Commented May 18, 2018 at 5:11
  • That is not a button, but hidden field. – xxxmatko Commented May 18, 2018 at 5:12
  • I might be wrong but I think <input name="submit" type="hidden" value="Reverse Geocode"> is what you are looking for. If it's not then why not just use onload event to trigger something? – NoOorZ24 Commented May 18, 2018 at 5:15
  • What is your goal actually? You are asking about button which is "clicked" by default, but your html shows an hidden input field. – xxxmatko Commented May 18, 2018 at 5:17

Reset to default 7

You can do as following:

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

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

At first, your button is not a button. It's a a 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();

Trigger click event on the button as soon as document is ready.You have to write the click event as shown below.

$(document).ready(function(){

    $("#yourButtonId")[0].click();

});  

Now i understand your question, You want default click in your submit button. Try click event, It will trigger the submit.

<script>
   $('#submit').trigger('click');
</script>

In JavaScript

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