JavaScript check form by Dreamweaver
Hi guys
one more question.
First let me say that my experience of JavaScript is VERY limited.
I have a script that is generated by Dreamweaver to check the form. Yet it does not check if there is a dot after "@" sign.
Here's the copy of the script
<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 a number between '+min+' and '+max+'.\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 == '');
} }
//-->
</script>
I made some changes to inclu a dota and a check against it. Here's the copy of the script:
<script type="text/javascript">
<!--
function MM_validateForm() { //v4.0
if (document.getElementById){
var i,p,dot,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('@');dot=val.indexOf('.');
if ((p<1 || p==(val.length-1)) && (dot<p || dot==(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 a number between '+min+' and '+max+'.\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 == '');
} }
//-->
</script>
the changes are:
var i,p,<Adition Made by me>dot</Adition>,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
and
if ((p<1 || p==(val.length-1)) <Adition made by me>&& (dot<p || dot==(val.length-1))</adition> errors+='- '+nm+' must contain an e-mail address.\n';
Could anyone tell me what could be the error, cause when I run this check on the form, it still doesn't show an e-mail with an absent dot
Don\'t post if you\'ve got nothing constructive to say. Flooding is annoying
