In this example, I’m going to use a mixture of Angular JS and vanilla Java Script.
This regular expression pattern is very useful to implement a strong and complex password.
Escapes or unescapes a Java Script string removing traces of offending characters that could prevent interpretation.
You want to be sure that your visitors enter data into the HTML fields you have "required" for a valid submission.
Below is the Java Script code to perform this basic check to see if a given HTML input is empty or not.
To show the password strength to the user, we’re going to use a rectangle that contains a color.
We’ll say that a red rectangle holds a weak password, orange medium, and green a strong password.
This chapter describes Java Script regular expressions.
You construct a regular expression in one of two ways: Using a regular expression literal, which consists of a pattern enclosed between slashes, as follows: Regular expression literals provide compilation of the regular expression when the script is loaded.
The last example includes parentheses which are used as a memory device.
The match made with this part of the pattern is remembered for later use, as described in Using parenthesized substring matches.
