Restriction validation for single line text field

[Sirri]

Hi All,

Please let me know how to apply these all conditions. I have one single line text field ( Name of the project).

I should want to restrict that field as per the below requirement:

Name of the project  can't contain special characters, such as / : \ ~ & % ; @ ' " ? < > | # $ * } { , + = [ ], can't begin with an underscore, can't begin or end with a period, and must be 64 or fewer characters.

Please provide the code.

Thank you.

@Sirri You can do onSubmit or onChange script below is sample script.

function onSubmit() {
  var projectName = g_form.getValue('name_of_project'); // Replace 'name_of_project' with your field name.

  // Disallowed special characters.
  var specialCharPattern = /[\/:\\~&%';"<>|#\$\*\}\{\[\],+=]/;

  // Check for special characters.
  if (specialCharPattern.test(projectName)) {
    g_form.showErrorBox('name_of_project', 'Project name cannot contain special characters like / : \\ ~ & % ; @ \' " ? < > | # $ * } { , + = [ ]');
    return false;
  }

  // Check if the string starts or ends with a period or underscore.
  var regex = /^[a-zA-Z0-9][a-zA-Z0-9\s\-._]{0,62}[a-zA-Z0-9]$/;

  if (!regex.test(projectName)) {
    g_form.showErrorBox('name_of_project', 'Invalid project name. Project name must be alphanumeric, cannot start with underscore or period, and cannot contain special characters.');
    return false;
  }

  return true;
}

Hi @Sirri Try below onChange Client Script 

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') {
        return;
    }

    var projectNamePattern = /^[^_\s][^\/:\~\&\%\;\@\^\{\}\[\]\<\>\|\#\$\*\?\'\"\+\=\,\.]{1,63}[^\.]$/;
    if (!projectNamePattern.test(newValue)) {
        g_form.showFieldMsg('u_name_of_the_project', 'Name of the project cannot contain special characters, cannot begin with an underscore, cannot begin or end with a period, and must be 64 or fewer characters.', 'error');
        g_form.setValue('u_name_of_the_project', oldValue); 
    } else {
        g_form.hideFieldMsg('u_name_of_the_project');
    }
}

Hi Sid,

if (!projectNamePattern.test(newValue))

Thank you
