Regex validation on integer field

[richard38]

Hello, I'm trying add some validation to an integer field. The validation is for positive, whole numbers. I've found a regex example that works, but only for numbers 1-999.

      var regExTest = /^[1-9][0-9]*$/;      

      g_form.hideFieldMsg("u_regex_test", true);

      if(!regExTest.test(newValue)){

              g_form.setValue("u_regex_test", "");

              g_form.showFieldMsg("u_regex_test","Enter a valid integer", "error");      

      }

My understanding is that the '*' represents the number of items being validated, similar to adding {0, } for min/max numbers. I've tried this in various online regex validators and they all show that this validates correctly, but it doesn't work as anticipated. Am I missing something?

thank you

Thanks everyone. What seems to be happening is when the newValue is entered, and is four digits, it now has a comma. Once I included the comma in the regex it worked.

This works:

var regExTest = /^[1-9][0-9,]*$/;

If you only want to restrict the field value as Integer , then you can try below script. it worked for me.

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

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

          return;

    }

var regexp =/^\d+$/;

  if(!regexp.test(newValue))

  {

    alert('Please enter Numbers. Only numbers are allowed');

  g_form.setValue('space_added','');

  }

}

N.B :   "space_added" is the field name.
