Allow only numeric input in textbox using AngularJs
In this
article, I am sharing code sample for allow only numeric input in textbox using
keydown, keypress jQuery.
The example for allow only numbers in textbox as following
-
$(function () {
$("#txtloanAmount").keydown(function (e) {
allowOnlyNumber(e);
});
$("#txtmonths").keydown(function (e) {
allowOnlyNumber(e);
});
var allowOnlyNumber = function (e) {
// Allow: backspace, delete, tab, escape, enter and .
if ($.inArray(e.keyCode, [46, 8, 9,
27, 13, 110]) !== -1 ||
// Allow: Ctrl+A, Command+A
(e.keyCode === 65 && (e.ctrlKey === true || e.metaKey === true)) ||
// Allow: home, end, left, right, down, up
(e.keyCode >= 35 && e.keyCode
<= 40)) {
// let it happen, don't do anything
return;
}
// Ensure that it is a number and stop the keypress
if ((e.shiftKey || (e.keyCode < 48
|| e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) {
e.preventDefault();
}
}
});
