Hi,

You can write an on change client script on Email ID field with the following script in it.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	if (isLoading || newValue === '') {
		return;
	}else if(oldValue != newValue){
		var reg = /^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/;
		if (!reg.test(newValue)){
			alert('You should enter a valid email address');
			g_form.clearValue('u_email_id'); //Replace email id field name
		}
	}
}

Thanks!

Hi Veera,

For this u can first create a script include and call this script include on server side using business rule. I have tried this practically and it works.

1) Create script include

Name: validateEmailAddress

        API Name: (this field value is automatically populated)

        Application: (this field value is automatically populated)

        Accessible from: All application scopes

        Active: Selected (checked)

        Description: On demand Script Include to validate email address syntax using regular expressions.

function validateEmailAddress(emailStr){
// Use JavaScript coercion to guarantee emailStr is a string
emailStr = emailStr + '';
// Compare emailStr against the allowed syntax as specified in the regular expression
// If emailStr has allowed syntax, return true, else return false
if(emailStr.match(/^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/)){
return true;
}
else {
return false;
}
}

2) Create business rule

1. Name: Email Address Syntax Validate
           Table: NeedIt [x_<your_company_code>_needit_needit]
           Active: Selected (checked)
           Advanced: Selected (checked)

2. Switch to the When to run section and continue configuring the Business Rule:

           When: Before
           Insert: Selected (checked)
           Update: Selected (checked)

3. Click the Submit button.

4. Switch to the Advanced section.

var isEmail = validateEmailAddress(current.u_requested_for_email);
// If isEmail is false (email address syntax is not valid) do not save
// the record. Write an error message to the screen.
if(isEmail == false){
gs.addErrorMessage(current.u_requested_for_email + " is not a valid email address. You must provide a valid email address.");
current.setAbortAction(true);
}

And also refer below link,

If u find my answer helpful. Kindly mark it as correct or helpful.

Thanks,

Priti

hi

check this code in background script

var emailAddr='abc123@gmail.com';
if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(emailAddr))
  {
    gs.print('yes')
  }
else{
   gs.print("You have entered an invalid email address!")
}

Hi Veera,

Do you want to validate the email format like 3 chars and 3 digits followed by @gmail.com? or do you want to validate whether the entered email is abc123@gmail.com or not? What is your requirement?
