User should able to enter number and range should be 0 to 65536

[lucky24]

Hi Team,

We have one port number field and the user should only be able to enter 0 to 65536 and it should also accept (, and – Special characters)  

For example :  22-23, 25, 80, 443, 2001-2020

Can someone please let me know how can I achieve this?

Thanks

Hi @lucky24,

You may try with following onChange Client Script.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

   if (isLoading || newValue === '') {

      return;

   }

    var pattern = /^(?:[0-9]|[1-9][0-9]|[1-9][0-9]{2}|[1-9][0-9]{3}|[1-5][0-9]{4}|[6][0-4][0-9]{3}|65[0-4][0-9]|655[0-2][0-9]|6553[0-5][0-9]|65536)$/;

    if (!pattern.test(newValue)) {

        alert("enter correct values");

        g_form.setValue('short_description','');

    }

}  

Please mark my response as correct and helpful if it helped solved your question.

Thanks,

If the field is on a table, you can use an onChange client script that contains a regex.  If the field is on a catalog item, you can create a "Variable Validation Regex" and apply it to the field.

Hello @lucky24 ,

To achieve this requirement, you can create on change client script on "port number" field and use regex for validation as below -

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

   //Type appropriate comment here, and begin script below

  var portField = g_form.getValue('number_field'); //replace the field name
    
    // Regular expression to validate port numbers and ranges
    var regex = /^\s*(6553[0-6]|655[0-2][0-9]|65[0-4][0-9]{2}|6[0-4][0-9]{3}|[1-5][0-9]{4}|[0-9]{1,4})(\s*-\s*(6553[0-6]|655[0-2][0-9]|65[0-4][0-9]{2}|6[0-4][0-9]{3}|[1-5][0-9]{4}|[0-9]{1,4}))?(\s*,\s*(6553[0-6]|655[0-2][0-9]|65[0-4][0-9]{2}|6[0-4][0-9]{3}|[1-5][0-9]{4}|[0-9]{1,4})(\s*-\s*(6553[0-6]|655[0-2][0-9]|65[0-4][0-9]{2}|6[0-4][0-9]{3}|[1-5][0-9]{4}|[0-9]{1,4}))?)*\s*$/;
   

    // Validate the port number field against the regular expression
    if (!regex.test(portField)) {
        alert('Invalid port number format. Please enter values between 0 and 65536, using commas and hyphens as separators.');
    }
   
}

I have tried it in my PDI and it worked for me.
