asked on

onchange and onkeyup together.

Hi,
I wrote a validation function,which makes for example 1234567 ---> 1,234,567

I use it in a textbox and I wanna also use onchange event for the same textbox. The function I wrote runs when unkeyUp activated.

However unkeyUp and onchange events doesn't work together?

Do u have any idea?

My function:
function Fcm2(thisis) {
var tempstr,newstr,str,i,str2 ;
var commapos,aftercomma,commacount;
i=0;
str = thisis.value;
if (str.indexOf(".") < 0) {
while ( 15 > i) { str = str.replace(",",""); i=i+1; }
commacount=0;
commapos=str.indexOf(";");

if (commapos>=0) { aftercomma=str.substr(commapos); str=str.substr(0,commapos); }
else aftercomma="";

if (str.length > 3) {
tempstr=str;
newstr="";
while (tempstr.length > 3)
{ newstr=","+tempstr.substr(tempstr.length-3)+newstr;
tempstr=tempstr.substr(0,tempstr.length-3); }
thisis.value = tempstr+newstr+aftercomma;
}
}
return true;
}

---------------------
function calcul(thh){
alert("change");
}

function press(thisis){
if(window.event.keyCode < 47 && window.event.keyCode > 57) { window.event.keyCode = 9008999; }
if(window.event.keyCode == 9008999) {return false; } else {Fcm(thisis) }
}

---------------------
<td width=80% height=20><input value="" class=numstd onchange="calcul(this)" onkeyUp="press(this)" name=deneme size=40 maxlength=40></td>

if you want to run calcul function just after press function you must call it in the onkeyup too. onchange event just triggers when you exit the field (if its value has changed, of course). there's no evaluation of value changes when pressing keys, just when exiting.

something like that:

function calcul(thh){
if (thh.value != thh.oldValue) alert("change");
thh.oldValue = thh.value;
}

<td width=80% height=20><input value="" class=numstd onkeyUp="press(this);calcul(this);" name=deneme size=40 maxlength=40 oldValue=""></td>

hope it helps ya.

peace

No alambres with this method it goes to database every time a key is pressed!!!
This is not that I want to.

With onkeyup I want to use my validate function but onchange doesnt work when I use it.

this is then:

while ( 15 > i) { str = str.replace(",",""); i=i+1; }
commacount=0;
commapos=str.indexOf(";");

if (commapos>=0) { aftercomma=str.substr(commapos); str=str.substr(0,commapos); }
else aftercomma="";

if (str.length > 3) {
tempstr=str;
newstr="";

Simply,
I want to use both validation and onchange event?

If you write 1234567 to the textbox it will make it 1,234,567 every time you write a number and then if you press tab button it will save it to the database?

Do you have a solution for that?

Thank you....

alambres,
It is nor efficient to use onBlur because I wanna do some savings when data is changed in the textbox...

alambres

what do you understand by "data is changed"? I repeat: onchange event triggers when EXITING (=ONBLUR) the field. You should check if the value's changed when blur. Otherwise, you'll be doing the saving to DB every keyPress, which you said you don't want to. So?

BUT how can I check easily(without global variables) if the value's changed when blur?

NetGroove

You kill the onChange event by changing the field value by previous events.
So you have to check for changes on your own.

Like this:

<input type=text value="" onFocus="this.oldValue=this.value" onBlur="if(this.value!=this.oldValue)alert('changed')">

Good luck,
