calling input button click manually

CW
In my javascript, when enter key is pressed, I want to simulate the effect
of clicking a button.

var mykey;
var posted=false;

if (window.Event){
document.captur eEvents(Event.K EYDOWN);
}

document.onkeyd own = myKeyDown;

function myKeyDown(e){

if (window.Event){
mykey = e.which;
}
else{
mykey = event.keyCode;
}
//alert(mykey);

var theform;
if (window.navigat or.appName.toLo werCase().index Of("netscape") > -1) {
theform = document.forms["Form1"];
}
else {
theform = document.Form1;
}

if ((mykey==13) && (posted==false) && (theform.btnSen d.click))
{
posted=true;
theform.btnSend .click();
}
}

Everything works fine in IE4 to IE6. But NS behaviour is really bizzare.

Thing work as expected in NS7.

In NS6, theform.btnSend .click() does not cause form submission.

In NS4, it complains that theform.btnSend .click() does not exist (despite
having passed the if test that verifies theform.btnSend .click exists).

Any idea?

Thanks

It's generally a bad idea to do anything as drastic as submit a
form on keydown. That leaves the keyup event in limbo, with
unpredictable consequences.

I don't have NS6 installed, but NS4 submits for me when the button's
click() method is called.

Is there a reason why you're calling the click() method, instead of
just directly invoking the form's submit() method?

because there are 2 buttons on the form. If I call submit, it doesn't
specify which button is pressed.

thanx

You can set a hidden form field to tell which was pressed,
or better, redesign it so that it will work without Javascript,
for those who have it disabled.

Please don't top post. Respond *after* the message you're
