you can use numeric fields force numeric data capture only. alternatively, can use regular expressions force numeric or alpha data capture on text fields. attached uses following regular expressions:

 

 

// form1.page1.tf-numeric-only::exit - (javascript, client)

 

 

if (!(this.isnull)) {

  var tf = this.rawvalue;

  // \d match character not in range 0 - 9

  var regexp = /\d/;

  if (regexp.test(tf)) {

    xfa.host.messagebox("the field must numeric.","validation",1);

  }

}

 

// form1.page1.tf-alpha-only::exit - (javascript, client)

if (!(this.isnull)) {

  var tf = this.rawvalue;

  // \d match character in range 0 - 9

  var regexp = /\d/;

  if (regexp.test(tf)) {

    xfa.host.messagebox("the field must alpha.","validation",1);

  }

}
