如何在javascript中将字符串中的所有'\\'和'/'字符替换为' - '

Question

I have the following javascript.

window.location.href = _searchUrl + query.replace(/\s+/g, '+')
                                         .replace('/', '-')
                                         .replace('\\','-')

this replaces all spaces with + and only the first \\ and first / with a - .

i need to make it replace ALL \\ and / with a -

Any suggestions? or should this be URLEncoded?

Answer 1

尝试：

query.replace(/\s+/g, '+').replace(/[/\\]/g, '-')

Answer 2

The first regular expression replaces ALL the spaces because it has a 'g' modifier.

You need it for the other two 'replaces'

Answer 3

You're basically doing a subset of the URI encoding. Use encodeURI() or encodeURIComponent() as appropriate. See Comparing escape(), encodeURI(), and encodeURIComponent() (escape() is deprecated).

Assuming _searchUrl is something like

http://mysite.com/search?q=

then you should do this:

window.location.href = _searchUrl + encodeURIComponent(query);

There is no need (or reason) to reinvent (partially) URI encoding rules with regular expressions.
