Number only with number limit to 10 digits for variable

[servicenowsnow]

I'm working on one of catalog development , one variable restricted for only numbers ( we need to update only numbers ...if we give letters it should give error). and the number limit to 10 digits only.

Please help me on code needed for onchange client script.

Hi there,

Something like this?

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

	if (isLoading || newValue === '') {
		return;
	}

	g_form.hideFieldMsg('your_variable', true);
	
	var val = newValue;
	var msg = getMessage('some message');

	if((isNaN(val) == true) || (val.length > 10)) {
		g_form.showFieldMsg('your_variable', msg, 'error');
	}

}

If my answer helped you in any way, please then mark it as helpful.

Kind regards,

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

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

          return;   }

    //Type appropriate comment here, and begin script below

  var age=g_form.getValue('variable name');

  if (isNaN(age) )

    {

  alert("value should be in number");

  g_form.setValue('Variable name','');

  return false;

    }

if(age.length!== 10){

alert("number should be 10 digits");

return false;

}

}
