Fahid Posted February 18, 2006 Share Posted February 18, 2006 HI Guys!I wanted to make an input box to accept only numeric (int) values, to do that I wrote following function.[code]function is_int(Key) {/* 48 is ASCII code for 0 and 57 is for 9 */ //alert(Key); for(i=48;i<=57;i++){ if(Key == i) return true; } return false;}[/code]and my input box look like this[code]<input type="text" name="quantity" id="quantity" size="30" maxlength="3" value="1" onkeypress="return is_int(event.keyCode);" />[/code]Now! when I use IE6 or Opera, everythings just going perfect, But when I use Firefox, I got a problem.Firefox make it impossible to type anything in the input box, not even integers.Infact Firefox return [b]0[/b], not the actuall ASCII code of the key that was pressed.[!--sizeo:6--][span style=\"font-size:24pt;line-height:100%\"][!--/sizeo--]Any Idea how to get it right ?[!--sizec--][/span][!--/sizec--] Quote Link to comment https://forums.phpfreaks.com/topic/3462-firefox-is-not-responding-to-eventkeycode-method/ Share on other sites More sharing options...
ryanlwh Posted February 20, 2006 Share Posted February 20, 2006 stumbled upon this line of code[code]key = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;[/code]That should do it.

Fahid Posted February 21, 2006 Author Share Posted February 21, 2006 Thanks for response ryan, but I still can't find out, how exactly to do it.this is a sample page which uses the script[code]<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /><script type="text/javascript">/*This funtion helps to make an input-box to only accept integers*/function is_int(Key) {/* 48 is ASCII code for 0 and 57 is for 9 */ /* ryanlwh's code Key = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode; */ //alert(Key); if(Key == 13) return true; for(i=48;i<=57;i++){ if(Key == i) return true; } return false;}</script><title>Numeric Only TextBox</title></head><body><input type="text" onkeypress="return is_int(event.keyCode);" /></body></html>[/code]When I use [code]<input type="text" onkeypress="return is_int(event.keyCode);" />[/code]IE and Opera works just as I want, but Firefox doesn't.AndWhen I use [code]<input type="text" onkeypress="return is_int(event.charCode);" />[/code]Firefox works, but neither IE nor OperaOKI changed my javascript to this[code]function is_int(empty) { // in Firefox navigator.appName returns "Netscape". if(navigator.appName == "Netscape") Key = event.charCode; else Key = event.keyCode; alert(Key); // removed the rest of code for test return false;}[/code]Still IE and Opera respond well, but not Firefox.

ryanlwh Posted February 22, 2006 Share Posted February 22, 2006 this is what i'm using. i forgot how i googled it but it worked for me[!--html--][div class=\'htmltop\']HTML[/div][div class=\'htmlmain\'][!--html1--]<[color=blue]input type[/color]="[color=orange]text[/color]" onkeypress="[color=orange]return is_int(event);[/color]" />[!--html2--][/div][!--html3--][code]function is_int(event) { var Key = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode; // the following is copied and pasted from yours if(Key == 13) return true; for(i=48;i<=57;i++){ if(Key == i) return true; } return false;}[/code]may i suggest another way to check the keycode[code]function is_int(event){ var Key = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode; if(Key==13 || (Key >= 48 && Key <=57)) return true; else return false;}[/code] Quote Link to comment https://forums.phpfreaks.com/topic/3462-firefox-is-not-responding-to-eventkeycode-method/#findComment-12184 Share on other sites More sharing options...
