There are many ways with help of which we can apply validations on date. Let us discuss one from them below which is most preferred way.
Here, we already said that there are many ways like check validation of date using regular expressions or by using date.parse() function.
Today, here in this tutorial we are going to discuss date validation using regular expression, in next article we will understand our next concept which is done with understanding of date.parse() function.
Now, let us understand our regular expression concept with help of example given below.
- For this first of all we here create a basic structure of html. For this we use html, head, title and body with script tag. We hope you know about the basic structure of html and which html tag is used for which concept.
- Now, here as we see in above codes. First of all we create some headings tag. Then our main code starts, in which paragraph tag is created from html. Here, as we see that we did not use our paragraph for any other purpose, we only give here a class to it.
- This all validation is done using if condition. If our date is valid then a line containing text Your provided date is in valid format is display otherwise if the condition get wrong which means if it is in invalid format then Given date provided is in invalid format is executed.
