HI,

I have used this function YY_checkform() from yaromat for some time.

If you recognise it I could use some help

I am trying to validate a date, radio button and a check box. but I can't seem to get the format right to do the validation.

This is what I have tried and part of it works:

onclick="YY_checkform('Contact_Us','email','#S','2','\'Email Address\' is not valid.', 'StartDate','99/99/999','3','\'Start Date\' is not valid.');return document.MM_returnValue"

Here is the function:

<!--
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}

function YY_checkform() { //v4.71
//copyright (c)1998,2002 Yaromat.com
var a=YY_checkform.arguments,oo=true,v='',s='',err=false,r,o,at,o1,t,i,j,ma,rx,cd,cm,cy,dte,at;
for (i=1; i<a.length;i=i+4){
if (a[i+1].charAt(0)=='#'){r=true; a[i+1]=a[i+1].substring(1);}else{r=false}
o=MM_findObj(a[i].replace(/\[\d+\]/ig,""));
o1=MM_findObj(a[i+1].replace(/\[\d+\]/ig,""));
v=o.value;t=a[i+2];
if (o.type=='text'¦¦o.type=='password'¦¦o.type=='hidden'){
if (r&&v.length==0){err=true}
if (v.length>0)
if (t==1){ //fromto
ma=a[i+1].split('_');if(isNaN(v)¦¦v<ma[0]/1¦¦v > ma[1]/1){err=true}
} else if (t==2){
rx=new RegExp("^[\\w\.=-]+@[\\w\\.-]+\\.[a-zA-Z]{2,4}$");if(!rx.test(v))err=true;
} else if (t==3){ // date
ma=a[i+1].split("#");at=v.match(ma[0]);
if(at){
cd=(at[ma[1]])?at[ma[1]]:1;cm=at[ma[2]]-1;cy=at[ma[3]];
dte=new Date(cy,cm,cd);
if(dte.getFullYear()!=cy¦¦dte.getDate()!=cd¦¦dte.getMonth()!=cm){err=true};
}else{err=true}
} else if (t==4){ // time
ma=a[i+1].split("#");at=v.match(ma[0]);if(!at){err=true}
} else if (t==5){ // check this 2
if(o1.length)o1=o1[a[i+1].replace(/(.*\[)¦(\].*)/ig,"")];
if(!o1.checked){err=true}
} else if (t==6){ // the same
if(v!=MM_findObj(a[i+1]).value){err=true}
}
} else
if (!o.type&&o.length>0&&o[0].type=='radio'){
at = a[i].match(/(.*)\[(\d+)\].*/i);
o2=(o.length>1)?o[at[2]]:o;
if (t==1&&o2&&o2.checked&&o1&&o1.value.length/1==0){err=true}
if (t==2){
oo=false;
for(j=0;j<o.length;j++){oo=oo¦¦o[j].checked}
if(!oo){s+='* '+a[i+3]+'\n'}
}
} else if (o.type=='checkbox'){
if((t==1&&o.checked==false)¦¦(t==2&&o.checked&&o1&&o1.value.length/1==0)){err=true}
} else if (o.type=='select-one'¦¦o.type=='select-multiple'){
if(t==1&&o.selectedIndex/1==0){err=true}
}else if (o.type=='textarea'){
if(v.length<a[i+1]){err=true}
}
if (err){s+='* '+a[i+3]+'\n'; err=false}
}
if (s!=''){alert('The required information is incomplete or contains errors:\t\t\t\t\t\n\n'+s)}
document.MM_returnValue = (s=='');
}
//-->

Thanks!
