Form Validation

Copy linkTweet thisAlerts:
Jan 27.2005

I have 4 fields. If the user fillin one, then, they all must.
I have this function and it’s working good:

[code]
var count = 0;
if ( document.registration.fld1.value != “” ) ++count;
if ( document.registration.fld2.value != “” ) ++count;
if ( document.registration.fld3.value != “” ) ++count;
if ( document.registration.fld4.value != “” ) ++count;
if ( count != 0 && count != 4 )
{
alert(“All details has to be complete”);
return false;
}
[/code]

My problem is that this function will tell me if one of’em is empty BUt I need to check the value inside each field as well. Check for numbers, dte and so on… How can I do it?

Thanks!

@David_HarrisonJan 27.2005 — Try this:function stringVal(str){

return ( conditionA && conditionB && conditionC ) // Your validations in here

}

var count=0;

if( document.registration.fld1.value.length>0 ){
if( stringVal(document.registration.fld1.value) ){ count++; }
}
if( document.registration.fld2.value.length>0 ){
if( stringVal(document.registration.fld1.value) ){ count++; }
}
if( document.registration.fld3.value.length>0 ){
if( stringVal(document.registration.fld1.value) ){ count++; }
}
if( document.registration.fld4.value.length>0 ){
if( stringVal(document.registration.fld1.value) ){ count++; }
}

if ( count == 0 || count == 4 ){
alert("All details have to be complete!");
}
