View Full Version : MM_validateForm() -- question

03-06-2012, 10:57 PM
I'm adding a text field named city. I'm trying to validate it using MM_validateForm() however I'm not sure how to add it into the javascript.

Can anyone help out?

<script type="text/javascript">
function MM_validateForm() { //v4.0
if (document.getElementById){
var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2]; val=document.getElementById(args[i]);
if (val) { nm=val.name; if ((val=val.value)!="") {
if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain an e-mail address.\n';
} else if (test!='R') { num = parseFloat(val);
if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';
if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
min=test.substring(8,p); max=test.substring(p+1);
if (num<min || max<num) errors+='- '+nm+' must contain the number '+min+'.\n';
} } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is required.\n'; }
} if (errors) alert('The following error(s) occurred:\n'+errors);
document.MM_returnValue = (errors == '');
} }

<input name="submit" type="submit" class="submit-button" onclick="MM_validateForm('name','','R','email','','RisEmail','answer','','RinRange4:4','city','message','','R ');return document.MM_returnValue" value="Submit" />

I don't really understand. That is ghastly DreamWeaver code! Just place the script in the <head> section of your page.

onclick="MM_validateForm('name','','R','email','','RisEmail','answer','','RinRange4:4','city','message','','R ');return document.MM_returnValue" value="Submit" />

Quizmaster: When counting down, what whole number follows 37?
Contestant: er, 19.
