Javascript: regex to replace some characters with their hexadecimal code


Tag : javascript , By : Dov

should help you out (This is for JavaScript, which is the language you asked about. Note that it will be fairly different in Java.)
In JavaScript, this is trivial using replace with a regular expression and passing in a function:
var str = "testing % & / # \" \\";
var result = str.replace(/[%&\/#"\\]/g, function(m) {
    return (m === '"' || m === '\\') ? " " : "%" + m.charCodeAt(0).toString(16);
});
var str = "testing % & / # \" \\";
var result = str.replace(/["\\]/g, " ").replace(/[%&\/#]/g, function(m) {
    return "%" + m.charCodeAt(0).toString(16);
});

Perl regex for 8 digit hexadecimal number (may be missing escape characters)

This might help you Your regex is using upper case A-F, but your folder has lower case. Use /^[0-9a-fA-F]{8}$/ to explicitly allow lower case, or /^[0-9A-F]{8}$/i to ignore case in the match.

Use RegEx to convert hexadecimal values in text into ascii characters

seems to work fine A regular expression matches strings against a pattern, and you can use these matches to perform replacements.
Your pattern does extract the hex value as $1 ...and then you replace it with $1 ...which is the exact hex value you've extracted.

Regex expression to replace text between start and end characters, but keep characters too

I wish this helpful for you Thomas is correct -- in this case, you do not need a regular expression. However, if you insist on using one (or want to expand this logic in the future to handle a range of characters), here it is:
var inputString = "This is <my> long <text>";
var newInputString = Regex.Replace(inputString, "(<[^>]+>)", "{$1}");
