Javascript Regex Replace-不替换所有必需的字符串

Question

I have no idea what is happening here..

model.attributes.data.Path.replace('/\\/g',""), @options.path.replace('/\\/g',"")

When doing :

console.log model.attributes.data.Path.replace('/\\/g',""), 
@options.path.replace('/\\/g',"")

the data is:

T2/T2_2, T2/T2_2

It returns this:

T2T2_2, T2/T2_2

So only the first path was replaced, but not the second one? Why would that be?

Answer 1

Aside from the fact you're matching backslashes ( \\\\ = \\ ), instead of forward slashes ( \\/ = / ), Don't put your regexes into the replace function as strings.

Use:

.replace(/\//g,"");

Instead of

.replace('/\//g',"");

Then it'll work just fine:

"T2/T2_2 , T2/T2_2".replace(/\//g,"");
// returns: "T2T2_2 , T2T2_2"

Otherwise, it'll just try to literally find the string '/\\//g' .

Also, to replace both forward and backslashes in 1 regex, try this:

"T2/T2_2 , T2\T2_2".replace(/\/|\\/g,"");
// returns: "T2T2_2 , T2T2_2"

# \/|\\ Matches:
# \/  - Forward slash
# |   - Or
# \\  - Backslash

Answer 2

Try:

model.attributes.data.Path.replace(/\//g,"")
@options.path.replace(/\//g,"")

/\\\\/g matches a backslash and /\\//g matches a forward slash.

Answer 3

尝试使用.replace(/\\//g,"")代替.replace('/\\\\/g',"") （正则表达式不是字符串）。
