替换javascript字符串中的任何字符

Question

I want convert this string:

string with characters like áéíóú

to

#################################

This "parágrafo".replace(/\\wW*/g, "#") returns "###á#####"

Answer 1

One option is using repeat()

 let str = 'string with caracthers like áéíóú'; let result = "#".repeat(str.length); console.log(result); 

Doc: repeat()

Answer 2

The other answers using .repeat() are probably better ways to do this. This answer mainly serves to explain what's wrong with your code and how it could be done correctly.

\\w doesn't match accented letters for some reason, that's why á ends up in the output. But even if this weren't a problem, it wouldn't match the spaces between words.

You can use . , which matches any character except newline.

 console.log("string with caracthers like áéíóú`".replace(/./g, "#")); 

If you also want to replace newlines with # , add the s modifier.

 console.log(`string with caracthers like áéíóú and also newlines`.replace(/./gs, "#")); 

Oops, that's a very new feature in ES2018, not available in all browsers yet. You can use /.|\\ng for better portability.

 console.log(`string with caracthers like áéíóú and also newlines`.replace(/.|\\n/g, "#")); 

Answer 3

"#".repeat("string with characters".length)

无需更换。

Answer 4

repeat() cannot be used in IE so I will suggest looping over to the str length to get string with value # .

 let str = 'string with caracthers like áéíóú'; let result =''; for(var i=0; i<str.length; i++){ result += '#'; } console.log(result); 

Answer 5

It looks like your regex lost a few characters somewhere (and gained a * ). It should be /[\\w\\W]/ instead:

 var str = "parágrafo".replace(/[\\w\\W]/g, "#"); console.log(str);
