Method description:
Combine multiple parameters into one path (see example for details)
grammar:
The code copy is as follows:
path.join([path1], [path2], [...])
Since this method belongs to the path module, you need to introduce the path module before use (var path= require("path") )
example:
The code copy is as follows:
path.join('/foo', 'bar', 'baz/asdf', 'quux', '..')
// returns
'/foo/bar/baz/asdf'
path.join('foo', {}, 'bar')
// throws exception
TypeError: Arguments to path.join must be strings
Source code:
The code copy is as follows:
// windows version
exports.join = function() {
function f(p) {
if (!util.isString(p)) {
throw new TypeError('Arguments to path.join must be strings');
}
return p;
}
var paths = Array.prototype.filter.call(arguments, f);
var joined = paths.join('//');
// Make sure that the joined path doesn't start with two slashes, because
// normalize() will mistake it for an UNC path then.
//
// This step is skipped when it is very clear that the user actually
// intended to point at an UNC path. This is assumed when the first
// non-empty string arguments starts with exactly two slashes followed by
// at least one more non-slash character.
//
// Note that for normalize() to treat a path as an UNC path it needs to
// have at least 2 components, so we don't filter for that here.
// This means that the user can use join to construct UNC paths from
// a server name and a share name; for example:
// path.join('//server', 'share') -> '////server//share/')
if (!/^[////]{2}[^////]/.test(paths[0])) {
joined = joined.replace(/^[////]{2,}/, '//');
}
return exports.normalize(joined);
};
