Recent value with KeyPress

Why don't you try for the onkeyup event. You don't even need to read the last character and concatenate it. Keypress event is a combination of keydown and keyup event. Below is the sample code to test the response when the keypress and keyup event occurs.

Test KeyPress event: 

<input type="text" id="fname1" onkeypress="upperCase(this.id)" />

Test KeyUp Event: 

<input type="text" id="fname2" onkeyup="upperCase(this.id)" />


<script type="text/javascript">
function upperCase(x)
{
var y=document.getElementById(x).value;
document.getElementById(x).value=y.toUpperCase();
}
</script>

During the test run, you will notice that the last character does not convert to its uppercase during the keypress event, but it gets converted during the keyup event. Also, the keypress event does not allow you to handle the control keys like - SHIFT, ALTER, CONTROL, while the keyup and keydown events allow you to handle these keys. Hope I have made my point clear to you. Thanks & regards, Niral Soni
