IE 7 won't call onchange after onkeypress fires (using enter key)

[TS]

I have searched and searched the internet for the solution but cannot find
it. I have an asp.net 2.0 application running the page, but everything is
good...inspecting the control in JS debugging I can see that the onchange
function is setup correctly.

The normal function of the textbox on tab out when the value has changed is
to fire onchange then onblur. When the value changes and I hit enter key,
onkeypress runs then onblur, but not onchange. The event is not raised. I
have added event listeners using attachEvent (which fires during tab out)
and it won't get called either.

I can't just call onchange() from the onkeypress handler because it will
always run even when the value doesnt change (I do a postback onchange so I
cant have it run unless the value really does change)

Please help me as I dont know what else to do.

thanks

Hello,

If press the enter key, it will trigger onkeypress event and do submit
directly without going through onblur and onchange event at all.
If you'd like to press enter key to do the postback only if the textbox
value is changed, you can store the old value and do the submit if the
value is changed in keypress event.
Please check the following code if it is what you want.

<asp:TextBox id="text1" runat="server" />

<script type="text/javascript">
var oldvalue = "";
function window.onload() {
var textbox = document.getElementById('text1');
oldvalue = textbox.value;
textbox.onkeypress = onkeypressed;

}

function onkeypressed(e) {

var newvalue = document.getElementById('text1').value;
e = window.event || e;
var k = e.keyCode || e.which;
if (k == 13 && oldvalue == newvalue)
return false;
oldvalue = newvalue;
}
</script>
