Is there any straightforward manner to make a character replacing in javascript of many chars in just one instruction with different replacement for each one, like it is possible in PHP?
I mean, something like:
replace('áéíóú', 'aeiou'); That replaces á with a, é with e, í with i, and so on...
Thanks a lot in advance,
Use regex with the global flag:
var map = { "á": "a", "é": "e", "í": "i", "ó": "o", "ú": "u" }; "áéíóú".replace(/[áéíóú]/g, function(m){ return map[m]; }); Not really. Try this:
var map = {'á': 'a', 'é': 'e', 'í': 'i', 'ó': 'o', 'ú': 'u'}; var result = 'áéíóú'.replace(/./g, function(m) { return map[m] ? map[m] : m; }); Yes, you can do that in JavaScript:
var str = "áéíóú"; var result = str.replace(/[áéíóú]/g, function(m) { switch (m) { case "á": return "a"; case "é": return "e"; case "í": return "i"; case "ó": return "o"; case "ú": return "u"; } }); Another way is a lookup table:
var replacements = { "á": "a", "é": "e", "í": "i", "ó": "o", "ú": "u" }; var str = "áéíóú"; var result = str.replace(/[áéíóú]/g, function(m) { return replacements[m]; }); Those work because replace can accept a regular expression, and the "replacement" can be a function. The function receives the string that matched as an argument. If the function doesn't return anything, or returns undefined, the original is kept; if it returns something else, that's used instead. The regular expression /[áéíóú]/g is a "character" class meaning "any of these characters", and the g at the end means "global" (the entire string).
