Detect type of submit(if it was by enter key or button click)
Question
I have the following code:
<head>
<script language="javascript">
function subimiti(event){
alert("Tipo do submit: "+event);
}
</script>
</head>
<body>
<form id="f1" name="form1" onsubmit="subimiti(event)" action="http://www.google.com">
<input type="text" id="meuId" value="Teste"/>
<input id="butao" type="submit" value="Subimeta u fórmi trem bão!!"/>
</form>
In my javascript funcition, i wish i could detect the event that causes the form submit, if it was by a enter click on my text field, or if it was by clicking on the button.

Since the keypress event fires the click event when there's a submit button, the only workaround that I can think of is having a type=button instead.
Pure javascript ( Fiddle ):
<form id="f1" name="form1" action="" onsubmit="subimiti(this)" method="POST">
<input type="text" id="meuId" value="Test" onkeypress="setEvent(event)"/>
<input id="butao" type="button" onclick="setEvent(event)" value="Subimeta u formi trem bao!!"/>
</form>
function subimiti(form)
{
event.preventDefault();
alert(form.getAttribute('event'));
}
function setEvent(event)
{
if(event.type == 'click')
{
document.form1.setAttribute('event','click');
subimiti(document.form1);
}
else if (event.keyCode == 13)
{
document.form1.setAttribute('event','keypress');
}
}
Using jQuery (cleaner/easier code in my opinion):
$(function(){
$('form').submit(function(){
alert($(this).attr('event'));
});
$("input#butao").on('click', function(e) {
$("form").attr("event", "click").submit();
});
$("input").on('keypress', function(e) {
if (e.which == 13)
{
$("form").attr("event", "keypress");
}
});
});
There's a click listener for butao only and enter listener for any input.
<form id="f1" name="form1" action="">
<input type="text" id="meuId" value="Teste"/>
<input id="butao" type="button" value="Subimeta u formi trem bao!!"/>
</form>
