Position of cursor when onkeypress ocurrs

[fabi]

Hello!

Somebody knows as to make the following one:

I have one input text associated to the event onkeypress.

The function of this event is to validate caracter that he is being typed at the moment. Exists a way of I to know where position of text is being typed caracter?

Thanks,

Fabi

I dont't know of any way to do that but I do know that JavaScript works fast enough that you should be able to just revalidate all of the characters. The user will not know the difference.

Input imagines one text with the following value: 00.000.000/0000-00.
In the first position alone the entrance of numbers and letter ' P ' is allowed. If the user typed the number above and suddenly he needs to change the first one to caracter for ' P ' the event onkeypress will be validating the entrance of the characters.
I need to have certainty that the user is trying to change the first one to caracter for ' P ' and not them excessively.
How I make I verify this? The value of input is 00,000,000/0000-00 and the value of the event is ' P '.

You are not at all clear. What exactly do you want the value to look like in the end?

I will try to explain again.

I made the following code:

function validator(event, myText, tipo) {
if (getObjBrow().isNetscape())
key = String.fromCharCode(event.which);
else
key = String.fromCharCode(event.keyCode);

var isForeign = /P/i;
var isNumeric = /^[0-9]+$/;

if( (isForeign.test(key) && (myText.value == '')) ||
isNumeric.test(key)) {
return true;
} else {
return false;
}
}

This code allows to the digitação of a number or 'P' in the first position and numbers in excessively.

Imagines that the user typed 00.000.000/0000-00 and later field any of the screen was for one.

Before submitting the form the user noticed that it needs to change 00.000.000/0000-00 for P0.000.000/0000-00.

Script that I made is not allowing that it makes this. The using one only obtains to type the 'P' if the field will be clean. I must leave to modify it.
