You have below things in your project: 1.var mainApp = angular.module("mainApp", ['ngRoute', 'ngResource']); mainApp.directive('allowPattern', [allowPatternDirective]); function allowPatternDirective() { return { restrict: "A", compile: function (tElement, tAttrs) { return function (scope, element, attrs) { // I handle key events element.bind("keypress", function (event) { var keyCode = event.which || event.keyCode; // I safely get the keyCode pressed from the event. var keyCodeChar = String.fromCharCode(keyCode); // I determine the char from the keyCode. // If the keyCode char does not match the allowed Regex Pattern, then don't allow the input into the field. if (!keyCodeChar.match(new RegExp(attrs.allowPattern, "i"))) { event.preventDefault(); return false; } }); }; } }; } 2. allow-pattern="^[a-zA-Z ]*$" /> If u think it resolve your issue please marked as answer.

Hello santosh, You can either use directive or simply write one javascript function to check data in input field with regular expression. here is regular expression :"/^[a-zA-Z0-9.\-\s]+$/i," to check space and alphabets. Hope this will help you

Hello Santosh, You can write your custom Angular JS directives something like as below. ( function (){ app.directive( 'onlyLetters' ,onlyLettersInput); function onlyLetters(){ return { require: 'ngModel' , link: function (scope,element,attr,ngModelCtrl){ function fromUser(text){ var transformedInput=text.replace(/[^a-zA-Z]/g, '' ); //console.log(transformedInput); if (transformedInput!==text){ ngModelCtrl.$setViewValue(transformedInput); ngModelCtrl.$render(); } return transformedInput; } ngModelCtrl.$parsers.push(fromUser); } }; }; })(); You can use this in html as below. input only-letters type = "text" id = "right-label" > Hope, this will help you out. Feel free to write if more information is required. Please don't forget to mark as answer if this helps.
