To display error msg when Requested for user email starts with 'ab' or 'AB'

[rishabh31]

Dear Team,

I am working on a catalog item containing a reference type variable 'requested_for_user'. Requirement is display error message if the user selected in 'requested_for_user' field has email that starts with either 'ab' OR 'AB'.

I tried to achieve this through on change client script (on requested_for_user) and below script, but no luck 

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }
var reqfremail = g_form.getReference("requested_for_user");
//if((reqfremail.substring(0,2) == "ab") ||(reqfremail.substring(0,2) == "AB")){
	if ((reqfremail.email.indexOf ("ab")>-1) || (reqfremail.email.indexOf ("AB")>-1)){
g_form.showFieldMsg("requested_for_user", "Selected user email starts with 'ab' OR 'AB'", "error");
}
//}
}

as throwing below error

the same error is displayed in both cases i.e., when using 'substring' OR 'indexOf'.

Even I tried to remove the Email value 'email' from the client script but still did not work.

Kindly help to get this work as expected.

Thanks in advance

Hello @rishabh31 

As you are using getReference, you must have to use callback function for the same.

Replace your script with mine:-

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }
var reqfremail = g_form.getReference("requested_for_user", requestEmail);

function requestEmail(reqfremail){
	if ((reqfremail.email.indexOf ("ab")>-1) || (reqfremail.email.indexOf ("AB")>-1)){
g_form.showFieldMsg("requested_for_user", "Selected user email starts with 'ab' OR 'AB', Please select", 'info');
}
}

}

Hi 

The below script is also working with the use of 'substring' in place of 'indexOf'

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }
var reqfremail = g_form.getReference("requested_for_user", requestEmail);

function requestEmail(reqfremail){
	//if ((reqfremail.email.indexOf ("ab")>-1) || (reqfremail.email.indexOf ("AB")>-1)){
if ((reqfremail.email.substring (0,2) < "ab") || (reqfremail.email.substring (0,2) < "AB")){
g_form.showFieldMsg("requested_for_user", "Selected user email starts with 'ab' OR 'AB', Please select", "error");
}
}

}

Hi @rishabh31 ,

Try like this

if (reqfremail.email.startsWith ("ab") || reqfremail.email.startsWith ("AB")){

g_form.showFieldMsg("requested_for_user", "Selected user email starts with 'ab' OR 'AB'", "error");

}

Before writting that indexOf if conditions, modify it to below. It should resolve the issue.

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }
var reqfremail = g_form.getReference("requested_for_user");
//if((reqfremail.substring(0,2) == "ab") ||(reqfremail.substring(0,2) == "AB")){
if(reqfremail.email){
	if ((reqfremail.email.indexOf ("ab")>-1) || (reqfremail.email.indexOf ("AB")>-1)){
g_form.showFieldMsg("requested_for_user", "Selected user email starts with 'ab' OR 'AB'", "error");
}}
//}
}
