How can I create a regular expression for excluding words with a specific starting pattern?
Consider the following list:
I need a regular expression that will match all words except "June" and "July" because they start with "Ju".
I attempted using ^[^ju], but this matches any word starting with "J" or "U". What I really need is to match words starting specifically with "Ju".
Check out this regular expression:
^([^a].*|a($|[^b].*))
This pattern matches strings that either do not start with a, or if they start with a there is not a b at the second position.
If you are familiar with look-around assertions, you can also try this one:
^(?!ab).*
Avoid relying on regular expressions for complement matches as it can be inefficient and often engine-specific. Opt instead to utilize a regex in conjunction with the not operator for better results.
If you're looking for a regex pattern that matches words beginning with "ju," the following code snippet will do the trick:
^[j][u].*
function retrieveWeekday() { var input = document.getElementById("input"); } <form> <input type="date" placeholder="dd:mm:yy" id="input"/> <input type="button" value="get weekday" onclick="retrieveWeekday()"/> ...
