This is a javascript question!!! why are you asking in the database section.
You might get better results asking in a forum where people who know javascript might go.

All i can say is investigate regular expressions this is a very simple one

Hi Arun

Please check this code.

Note :
1. Also make use of component level of validation to restrict the user to enter only numerics and characters "+" and "-"
2. If the application is india based then you can proceed with 91 as country code or keep an array of all country codes and change the validation accordingly.

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Mobile No. Validation</title>
<script type="text/javascript">
function validateMobNo(mobno){
	var mobno2;
	var flag=false;
	var mlen= mobno.length;
	//alert(mobno.substr(3,mobno.length-3));
	if(mobno.charAt(0)!='+' && mlen==10){
		mobno2="+91-"+mobno;
		alert("1>>your mobile wants to be in "+mobno2);
		flag=true;
	}
	else if(mobno.charAt(0)=='+'){
		if(mobno.substr(0,3)=='+91' && mobno.length==13){
			mobno2=mobno.substr(0,3)+"-"+mobno.substr(3,mobno.length-3);
			alert("2>>your mobile wants to be in "+mobno2);
			flag=true;		
		}
	}
	else if(mobno.indexOf("-")<0&&mobno.length==12 && mobno.substr(0,2)=='91'){
		mobno2=mobno.substr(0,2)+"-"+mobno.substr(3,mobno.length-2);
		alert("3>>your mobile wants to be in "+mobno2);
		flag=true;
		}
	else
		alert("Please correct your mobile No");
	if(flag==true)
	   document.mobvalidate.mobno.value=mobno2;
	else
		document.mobvalidate.mobno.focus()
	return flag;
		
}
</script>
</head>
<body>

Hope it solves your problem..

or using regular expressions do it in 4 lines of code, but I am not telling you what the regex is, you need to have a stab at it yourself

Regulare expressions are indeed the way to go for this type of activity. The type of code shown earlier should be avoided when much better alternatives exist.

Hi thanks for your advice i got idea through regular expression

my code is:

If you enter other than +91 it will show alert Message, by using this format we can change the input method for our convenient.

I think it will help for all.... Thank you.

Why don't you correct simple formatting problems for the user instead of saying it is an error? This will make your application more user friendly.
