Disable backspace key using Jquery

-
Disable backspace key in HTML form using Jquery in simple steps.

While user enters data into application if user accidentally press backspace button then it will redirect to previous page and all entered data would be lost. to eliminate this event we can disable the backspace key using Jquery.

 Following is the JQuery script tag you can add to the web page

$(document).keydown(function (e) {
    var nodeName = e.target.nodeName.toLowerCase();

    if (e.which === 8) {
        if ((nodeName === 'input' && e.target.type === 'text') ||
            nodeName === 'textarea') {
            // do nothing
        } else {
            e.preventDefault();
        }
    }
});

The above code can be used seamlessly with any web technology you are using. Hope this will help you in your web application.

Happy coding:)

Angular User Session Timeout example step by step

This functionality let the user know that their session is about to expire and that they would be logged out if they didn’t take action. I have written this functionality in Angular for my latest application.  If you are new to Angular 6 then read my article about Setting up Angular 6 step by step before jump to this article to get handy in Angular 6. Dealing with timers in Angular can be significantly different when using React components and subscriptions. The basic premises remains the same, though. We’ll have a service with a timer that will provide a Subject to which consumers of the service can subscribe. A React Subject provides an easy mechanism to trigger a “next” subscription to alert consumers that the timer has expired.   import { Injectable } from '@angular/core'; import { Observable, Subject, Subscription, BehaviorSubject} from 'rxjs/Rx'; @Injectable() export class IdleTimeoutService { private _count: number = 0; ...
