Hi,
I am blocked on this problem since so a long time that I prefer asking here my question...
I'd like, if the data isn't correct, that the user stay in the input zone. Everything is
ok with IE but not with Firefox.
Here is my code :
// Validation des données.
function demarrage_controles() {
if (FF) {
document.captureEvents(Event.KEYPRESS);
document.captureEvents(Event.CHANGE);
document.onkeypress = process_keypress;
document.onchange = process_change;
} else {
document.onkeypress = process_keypress;
for (i=0; i < document.forms[0].elements.length ; i++) {
document.forms[0].elements[i].attachEvent("onchange",process_change);
}
}
}
// On n'accepte que des chiffres.
function process_keypress(e) {
if (FF) {
if (e.target.tagName == "input" && !((e.which > 47 &&
e.which < 58) || e.which == 0 || e.which == 8 || e.which == 13)) {
return false;
}
} else {
if ((window.event.keyCode < 47 || window.event.keyCode > 58) &&
window.event.keyCode != 13) {
return false;
}
}
}
// On compare au dernier cumul.
function process_change(e) {
if (FF) {
if (e.target.id.substr(0,3) == "var" && e.target.alt != "")
{
if (Number(e.target.value) < Number(e.target.alt)) {
alert ("Vous ne pouvez pas saisir de données inférieures au dernier
cumul !");
e.preventDefault();
e.stopPropagation();
e.returnValue=false;
}
}
} else {
if (window.event.srcElement.id.substr(0,3) == "var" &&
window.event.srcElement.alt != "") {
if (Number(window.event.srcElement.value) <
Number(window..event.srcElement.alt)) {
alert ("Vous ne pouvez pas saisir de données inférieures au dernier
cumul !");
window.event.returnValue = false;
}
}
}
}
My problem comes from the process_change function in Firefox where I put everything I know
(stopPropagation etc...) but without success. The user go to the next field. In IE, the
window.event.returnValue = false is ok.
Do you have any clue ?
Thank you very much.
David.
