no tag found using with tagbar

[GeekaholicLin]

I want to use jsctags and tagbar in vim,but there were something wrong.

When I used them in vim,the tagbar always said 'no tag found'.

I used the command find . -type f -iregex ".*\.js$" -exec jsctags {} -f \; | sed '/^$/d' | sort > tags for a test file test.js, and it created a file named 'tags' in the directory.The file tags showes the result of the command successfully.

The content of file:

a	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/a/;"	f	lineno:1	type:void function()
b	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/b/;"	v	lineno:19	namespace:y	type:boolean
b	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/b/;"	v	lineno:29	type:number
e1	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/e1/;"	v	lineno:33	type:string
e3	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/e3/;"	v	lineno:33	type:number
Foo	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/Foo/;"	f	lineno:4	type:void function(?, ?)
func	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/func/;"	f	lineno:18	namespace:y	type:number function()
it	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/it/;"	f	lineno:23	type:!0 function(?)
method	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/method/;"	f	lineno:10	namespace:Foo.prototype	type:void function()
n	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/n/;"	v	lineno:23	namespace:it
prototype	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/class Foo \{/;"	v	lineno:4	namespace:Foo
x	D:\babun\.babun\cygwin\home\Garcin\test\test.js	/x/;"	v	lineno:12	namespace:Foo.prototype	type:string

But when I toggle the tagbar, it does not work.And I found a issue in the repo majutsushi/tagbar.

Are there any configs that I should write in my vimrc file to let it work correctly for js?
