here is my code and it's not working in my form.

<script type="text/javascript">
    function valid(){
        var pin_code=document.getElementById("pin");
        var user_mobile=document.getElementById("phone");
        var user_id=document.getElementById("email");
        var pat1=/^([0-9](6,6)+$/;
        var pattern=/^([0-9](10,10))+$/;
        var filter=/^([a-z A-Z 0-9 _\.\-])+\@(([a-z A-Z 0-9\-])+\.)+([a-z A-z 0-9]{3,3})+$/;

        if (!filter.test(user_id.vlaue)) {
            alert("Email is in www.gmail format");
            user_id.focus();
            return false;
        }
        if (!pattern.test(user_mobile.value)) {
            alert("Phone nubmer is in 0123456789 format ");
            user_mobile.focus();
            return false;
        }
        if (!pat1.test(pin_code.value))  {
            alert("Pin code should be 6 digits ");
            pin_code.focus();
            return false;
        }
    }
</script>

Here is the issue, when i submit the form whether i enter digits or characters in the mobile number or pin code it's accepting that value also. and when i am using these codes in partitions means like for email

<script type="text/javascript"> 
    function valid() { 
        var user_id=document.getElementById("email"); 
        var filter=/^([a-z A-Z 0-9 _\.\-])+\@(([a-z A-Z 0-9\-])+\.)+([a-z A-z 0-9 {3,3})+$/; 
        if(!filter.test(user_id.vlaue))  { 
            alert("Email is in www.gmail format"); 
            user_id.focus(); 
            return false; 
        } 
    } 
</script>

in this code it's working properly but it's not working when i am using all the codes in one single form.

Please help me. Thank You.

• Please give some examples of test data to enter, or even better use jsbin to create an example that we can see and test (just create some HTML elements and paste your JavaScript in) – M1ke Commented Feb 25, 2015 at 10:37
• 1 Your regex is broken. IMO this is the ONLY way to validate an email address: stackoverflow./a/201378/2594742 – AeroX Commented Feb 25, 2015 at 10:51

Just change pat1 and pattern to this:

var pat1=/^\d{6}$/;
var pattern=/^\d{10}$/;

Full working java-script as follows:

<script type="text/javascript">
function valid()
{
var pin_code=document.getElementById("pin");
var user_mobile=document.getElementById("phone");
var user_id=document.getElementById("email");
var pat1=/^\d{6}$/;
var pattern=/^\d{10}$/;
var filter=/^([a-z A-Z 0-9 _\.\-])+\@(([a-z A-Z 0-9\-])+\.)+([a-z A-z 0-9]{3,3})+$/;
if(!filter.test(user_id.value))
{
alert("Email is in www.gmail. format");
user_id.focus();
return false;
}
if(!pattern.test(user_mobile.value))
{
alert("Phone nubmer is in 0123456789 format ");
user_mobile.focus();
return false;
}
if(!pat1.test(pin_code.value))
{
alert("Pin code should be 6 digits ");
pin_code.focus();
return false;
}
}
</script>

change the pattern for the regular expression as below:

   var pat1=/^[0-9]{1,6}$/;
   var pattern=/^[0-9]{1,10}$/;

app.directive('validateAddress', function() {

return {
  require: 'ngModel',
  restrict: 'A',
  link: function(scope, element, attrs, modelCtrl) {
    modelCtrl.$parsers.push(function(inputValue) {
      if (inputValue == null)
        return ''
      //cleanInputValue = inputValue.replace(/[^\w]/gi, '');
      //cleanInputValue = inputValue.replace(/[^a-zA-Z0-9-\,\s\_\.\@\#]/g, "");
      cleanInputValue = inputValue.replace(/[^a-zA-Z0-9-\,\s\_\.\@\#\!\$\%\*\(\)\-\+\;\:\>\<\?\|\}\{\=]/g, "");
      if (cleanInputValue != inputValue) {
        modelCtrl.$setViewValue(cleanInputValue);
        modelCtrl.$render();
      }
      return cleanInputValue;
    });
  }
}
  })
