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

its working fine at my end. Can you provide screenshot .Try below on change client script

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

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

return

}

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

  if(!regexp.test(newValue)){  

  alert("Please enter valid characters");     g_form.setValue('urfieldname', '');  

  }  

}

Hi richcab

Here you go

if(/\D/g.test(newValue)){

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

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

      }
