Angular JS Function for Decimals , Integers validation in textbox
To allow only decimals or integers in the textboxes I have
very better function written below in only once place in app.js , and can be used
thought the application by just including the names.
Include below functions in your app.js
//included by Ilyas to allow integers, decimals in textbox
and restricts other values
//'YourAppName' è Write your application name
angular.module("YourAppName").
directive("onlyFloats", function () {
return {
require:
'ngModel',
restrict: 'A',
link: function (scope, element,
attr, ctrl) {
function inputValue(val) {
if (val) {
var digits
= val.replace(/[^0-9.]/g, '');
if (digits
!== val) {
ctrl.$setViewValue(digits);
ctrl.$render();
}
return
parseFloat(digits);
}
return undefined;
}
ctrl.$parsers.push(inputValue);
}
};
});
//included by Ilyas to allow only integers in textbox and restricts other values
//'YourAppName' è Write your application name
angular.module('YourAppName').
directive('onlyDigits', function () {
return {
restrict: 'A',
require: '?ngModel',
link: function (scope, element,
attrs, ngModel) {
if (!ngModel) return;
ngModel.$parsers.unshift(function (inputValue) {
var digits = inputValue.split('').filter(function (s) { return (!isNaN(s) && s != ' '); }).join('');
ngModel.$viewValue = digits;
ngModel.$render();
return digits;
});
}
};
});
Usage:
In your .html
or .chtml page include as below :) :) >>
For only digits just include
<input type="text" ng-model="XXXX" maxlength="100" only-digits >
Note: this textbox don't allow you to enter other than digits
For only decimals
<input type="text" ng-model="XXXX" maxlength="100" only-floats >
Note: this textbox don't allow you to enter other than digits and decimals
Hope you enjoyed.......
