Hello All,

I have written below script it does not as I expected

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

  if (isLoading || newValue == '') {

  return;

  }

  var subject = g_form.getValue('name'_var);

  var regexp = /^[a-zA-Z0-9.]*$/; // accept 0 to 9 numbers only

  if(!regexp.test(newValue) || subject>9999 || subject>zzzz )

  {

  g_form.showFieldMsg('name_var','Please enter only 4 digits','error');

  g_form.setValue('name_var','');

  }

  //Type appropriate comment here, and begin script below

}

Can any one help on this requirement

Hi Burra,

Create one onchange client script and use this below code for this requirement:

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

  if (isLoading || newValue === '') {

  return;

  }

  var letterNumber = /^[0-9a-zA-Z]+$/;

  if(!(newValue.match(letterNumber)) || newValue.toString().length>4)

  alert('It accepts only 4 digits or character');

  }

//Type appropriate comment here, and begin script below

g_form.showFieldMsg('short_description',"It accepts only 4 digits or character.",'error'); can be replaced with the alert statement.
