You cant do it in asp as it is a client side function, you will need to use javascript"

Code:

 onkeypress="document.form_name.submit();"

Hi,

What do you mean by "not working" ?
Please explain more.

Dr_Rock just give you an example as you provide no information of your code.

Try this example, whenever you type something (include backspace), "Testing" would be pop-up.

Code:

<html>
<script type="text/javascript">
function ClickbtnTest(){
alert('Testing');
}
</script>
<form name="Page">
Input Text:
<input type="text" onkeydown=ClickbtnTest() />
<input type="button" name="btnTest" value="Test" onClick=ClickbtnTest()>
</form>
</html>

You have to modify to what you want.

Hope it helps

thanks. the testing you posted worked.
but when i modified it to this:

Code:

<script type="text/javascript">
function ClickbtnTest(){
	document.form1.submit();
}
</script>

Code:

<form name="form1" method="post" action="index.asp">
<input name="medName" type="text" id="medName" size="50" width="350"onkeydown=ClickbtnTest() >
<input name="Display" type="submit" id="Display" value="Submit" onClick=ClickbtnTest()>
</form>

Hi,

Your code looks fine.

Again what does "it doesnt return anything" mean ??
Page not submitted?
Or go to blank page?
Or something else?

Do you get what you want when simply click the button?

Add testing line to see whether enter the javascript function or not

Code:

<script type="text/javascript">
function ClickbtnTest(){
	alert('Submit');
	document.form1.submit();
}
</script>

Hope it helps

thank you very much for the time.
the testing line works. the message box showed up.

but the behavior is not the same as clicking the button.

and while on that topic, i noticed that after typing a character, the onkeydown was automatically triggered. do you know a way where that event should only be called after pressing the enter key.

thanks.

Hi,

Add function to check whether Enter is pressed

Code:

<script type="text/javascript">
function CheckEnterKey(e) {
if(window.event) {
	// IE
	keynum = e.keyCode;
} else if(e.which) {
	// Netscape/Firefox/Opera
	keynum = e.which;
}
if (keynum == 13) {
	// 13: Enter
	return true;
} else {
	return false;
}
}
function ClickbtnTest(event){
	if (CheckEnterKey(event)) {
		document.form1.submit();
	}
}
</script>

<!-- CODE -->

<form name="form1" method="post" action="index.asp">
<input name="medName" type="text" id="medName" size="50" width="350" onkeypress=ClickbtnTest(event)>
<input name="Display" type="submit" id="Display" value="Submit" onClick=ClickbtnTest(event)>
</form>

Hope it helps

P.S. maybe you should ask moderator to move this thread to "HTML, JavaScript And CSS Help".
