Date and time values are used for many important functions such as searching, validation, and report generation. There is no standard format for dates in web applications, as people in different time zones and countries prefer different formats.
We can clearly see that the resulting date depends on your local time zone, as two different time zones are shown.
There is no single common format for dates, and we need to show date strings in different formats according to different situations. Basically, it is a two way process where we have to convert the string into a object first and then convert it back to a string in the format we prefer.
The initial process consists of converting the string provided by user input into a object. Let’s consider some of the common user input methods for dates.
These dialog boxes can be used to raise and alert, or to get confirmation on any input or to have a kind of input from the users.
Here we will discuss each dialog box one by one.
An alert dialog box is mostly used to give a warning message to the users.
For example, if one input field requires to enter some text but the user does not provide any input, then as a part of validation, you can use an alert box to give a warning message.
A confirmation dialog box is mostly used to take user's consent on any option.
The programs we have built so far have been seriously hampered by the fact that they were operating only on simple data types.
This chapter will add a basic understanding of data structures to your toolkit. By the end of it, you’ll know enough to start writing some useful programs.
Numbers, Booleans, and strings are the bricks that data structures are built from. But you can’t make much of a house out of a single brick.
