RE-Enable form button if authentication fails after disabling?

[monaya]

I'm disbaling a submit button on submit and validating some info. I'm trying to enable it again if the user fails authentication to re-enter data. Here is my code. Seems to work in Safari, IE but not Mozilla.


<script language="javascript">
function submitform()
{
if (document.getElementById("code").value != "4343")
{
window.alert("incorrect code. try again.");
document.getElementById("btnsubmit").value = "Send Feedback";
document.getElementById("btnsubmit").disabled = false;
return false;
}
else
{
document.form1.submit();
}
}
</script>

<input type="button" name="btnsubmit" id="btnsubmit" value="Send Feedback" onClick="this.value='Please wait...';this.disabled = true;submitform();"/>


it worked once, then when I rechecked it, the button stays disabled after a failed authentication? I hate when that happens because I implement the code all over!

Replace:


onClick="this.value='Please wait...';this.disabled = true;submitform();"

With:


onClick="submitform(this);"


And change your javascript to:


function submitform(me) {
if (document.getElementById("code").value != "4343") {
window.alert("incorrect code. try again.");
me.value = "Send Feedback";
if(me.disabled) {
me.disabled = false;
}
return false;
} else {
document.form1.submit();
}
}

If I remove:


onClick="this.value='Please wait...';this.disabled = true;submitform();"

then even my original code works actually.

I wanted to disable the submit button upon submit and display a please wait message. The part I wanted was to return the button back to its original state if the user fails the authentication statements.

Replace:


onClick="this.value='Please wait...';this.disabled = true;submitform();"

With:


onClick="submitform(this);"



Please read my whole post. When you call the submitform function, it will make the value please wait, and disable it.

Here's an example. Only Mozilla gives me trouble. The button is not reenabled after hitting OK in the alert:
