In my previous post, we created a Google Map Static API image using a Get URL. In one of my project, there was a requirement of HTML conversion into PDF document. So I wanted to add that Map Image into that PDF document. I used html2canvas and jsPDF libraries for that.
When I was trying to convert an HTML section with Google Static Map Image into the canvas, I faced a strange issue.

In an Angularjs project, if you are trying to add a datepicker having all features like MinDate MaxDate etc, you will hardly find any module which is performance efficient, bug-free and is requirement friendly like jQuery UI datepicker.

here I am going to share with you datepicker directive with basic options only like MinDate, MaxDate and default date, But as per requirement you can follow the same procedure to add more option in the directive.

Using tab index attribute in HTML form fields a user can easily navigate to the next or previous field by merely using the keyboard. But after some presses, Tab index focus caret secretly goes to a new dimension where it becomes impossible to press tab to get back that caret guy in place. ultimately we use to move back caret guy in place.
So during a requirement where I wanted to trap carret guy in a wrapper so that even after continous tabbing caret we never be able to leave that defined wrapper. After defined at input field that will focus on first defined form field automatically.

Small and easily customizable percentage progress bar can be help full in some cases when you want to show quick inline graphs or data notations. If the requirement is simple, we can’t proffer heavy libraries. For the same reason, I have written a small jQuery function to draw an animated progress bar. I have added some custom option which user can easily change in HTML attribute it self.
We can change Height, Width, Background or Bar color, Speed of animation. You can suggest me if other features can be added.

You can always find jQuery plugins or libraries for any type of requirement. But if we try to add plugins for every specific requirement, then we end up with a bunch heavy loaded library set which can take much time to load and can badly affect page efficiency. So I personally prefer to always try to code some specific function or method which can easily do the stuff without causing any hassle to page load time and including big sized libraries which always and have not required features which we will never need in future.
Here we will talk about very simple but very important function which can make longer texts look more concise and user-friendly. When we have a web page with longer texts in every section, it becomes very difficult for users to scroll those lengthy documents either they are on desktops or mobile devices. So “Read More” functionality comes to the rescue. This feature adds a read more link after longer texts trimming to 2-3 lines. So if a user wants to read the whole text, they can simply click on “Read More” and see the whole text.
Esc key on our keyboard can be useful even in Web pages and applications. We can use Esc key to close dialogue boxes or any custom popup modals. Here we will discuss even handling on ESC key press in which we can fire any event we want.
