I'm having a problem with a Login page I'm developing on ASP.net C#. The form works on IE, but not Firefox. Here's my sample:
<%@ Page Language="c#" Inherits="ClubCard.loginClubcard" CodeFile="loginClubcard.aspx.cs" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

<title>

<meta http-equiv="Page-Exit" content="blendTrans(Duration=0.25)" />
<link rel="stylesheet" type="text/css" href="styles.css">
<style>

}
</style>
<script language="javascript">

function actFocus()

{

}
}
function AbrirLogin()

I'm noticing that in this part...
function ValidarEnter(src)
{
if (event.keyCode == "13")
{
actLogin();
}
}
When I debug it on firefox, it just skips it.
I have already tried to add window.event.keyCode... and also switch "13" with just 13...
How could I work this around?
event.keycode was not supported by Firefox. Use event.which for firefox.
function checkKey(evt) {
var keyID = (evt.charCode) ? evt.charCode : ((evt.which) ? evt.which : evt.keyCode);
alert(keyID);
}
I was working on a project, when I faced the same issue. I did some RND and find out these 2-things;
e.keyCodeworks fine withonkeydown()function, no matter the browser is Chrome or Firefox.
Here is good practices for both Chrome & Firefox.
// HTML (Note onkeydown() function here)
<input id="anyId" onkeydown="return myFunction(event)" type="text" />
// JavaScript for it
function myFunction(e) {
var asciiValue = e.keyCode ;
alert ("ASCII Value: " + asciiValue ); // ASCII of pressed key
if(asciiValue >0){
return true;
}
else{
return false;
}
}
- But if we use
onkeypress()function in Firefox, thene.keyCodewill not work. For this purpose, adoptvar asciiValue= e.keyCode || e.charCode.
// HTML (Note onkeypress() function here)
<input id="anyId" onkeypress="return myFunction(event)" type="text" />
// JavaScript for it
function myFunction(e) {
var asciiValue = e.keyCode || e.charCode ; // It'll handle both Chrome & Firefox
alert ("Ascii Value: " + asciiValue); // ASCII of pressed key
if(asciiValue>0){
return true;
}
else{
return false;
}
}
function key_fir(e) { e = e || window.event || {}; var charCode = e.charCode || e.keyCode || e.which; if (charCode == 13) {
//write your code here Like $("#log_sub").click();
}
}
