使用正则表达式，我怎样才能在句子中得到“músicas”或“áaudio”这个词？

Question

I'd like to check a sentence in JavaScript. I'm using Web Speech API in Portuguese (PT-BR) by Google. So code follows:

[...]

// Writes the spoken sentence on a field
document.getElementById('text').innerHTML = result;

// Should check whether "músicas" is in sentence or not
if (/músicas/g.test(result) == true)
{
  document.getElementById("output").innerHTML = "Inside sentence";
}
else
{
  document.getElementById("output").innerHTML = "Not inside sentence";
}

[...]

The variable result stores the spoken sentence in Portuguese, for example, Eu gosto de músicas (Which means I like musics ). Then, the conditions should check, but it's not working with accentuations.

By the way, if I check something without accentuation, such as /fotos/g , it works perfectly!

Can anybody help me with this probably simple Regex issue?

Thank you.

To match accented vowels in a JavaScript regex, we can use the unicode character class:

if (/m[\u00FA]sicas/g.test(result) == true) {
    document.getElementById("output").innerHTML = "Inside sentence";
}

You can refer here for a table of accented characters and their Unicode equivalents.

Note that as others have mentioned, in pure JavaScript you do not need Unicode classes for this, but apparently you have an application which requires this.
