Disable form auto submit on iOS device on GO button press, but hide keyboard

Hello,

I am having a bit of an issue with getting a form not to auto submit on iOS devices (which I have solved using the following).

function disableEnterKey(e)
{
	var key;
	if(window.event)
		key = window.event.keyCode; //IE
		else
			key = e.which; //firefox

			return (key != 13);
			
		}

Open in new window


However I also need it to then hide the on-screen keyboard which is where I am a bit stuck.

The elements of the HTML of the form are as follows:

<form role="form" method="POST" name="level1buttons" id="level1buttons">
....
<input id="notes" name="notes"  type="text" class="form-control" onKeyPress="return disableEnterKey(event)" placeholder="Other comments">
....
<button type="button" class="btn btn-black" value="Exit" onClick="autoSubmit();">Save &amp; Finish</button>

Open in new window


The input field NOTES being what causes the form to submit, presumably by running autoSubmit() which is as follows:

function autoSubmit()
{
    var formObject = document.forms['level1buttons'];
    formObject.submit();
}

Open in new window


Is there a better way to do what I am achieving? My knowledge of JavaScript is rather limited.

Thanks,

Lee

greetings Lee Redhead, , ,  I do not know, or have ever heard of any javascript that can get the Operating system to change its operations, you say -  "However I also need it to then hide the on-screen keyboard which is where I am a bit stuck.", Since there are no OS changes, so then you can try and fool it into taking away the screen keyboard by dropping the Input focus (active input) with the javascript command   blur()   as in -
      document.activeElement.blur();


also you have gone to the trouble of blocking the carriage return key (number 13) in a text input, however, I have had much better results for form Submit Control by using the <form> onsubmit( )  event like -
    <form action="getpost.asp" onsubmit="return verifies(event);">

this onsubmit( )  is run for ALL of the ways a form can be submitted from the page, and Also you can use the  event  object to see which form Input had the focus then the event fired, you can verify that all inputs have an an entry, and block the submission for any reason you program into it, and you do not have to block the carriage return key in any input, if the button is touched, or any of 10 inputs press the carriage return key, then the   verifies( ) function runs. you can get the element that does the submit with   event.target   and if it is NOT a permitted submit element (by your standards) then block the submission.
