Validate paths using javascript

Question

I am asking users to enter path to controller files like

abc/cab
cde/ter/tyu

I am unable to validate it using

var regexString =/^([a-zA-Z\]+)*$/;

Can you please help me correct this. text like abc//text and abc/text/ and abc/text// and /abc/text also should return false. There should be no slash at beginning and ending also.

Try it like this:

var regexString = /^([a-z]+\/)*[a-z]+$/i;

Will work for:

abc/cab
abc/cab/bla

but won't for:

abc/cab/
/abc/cab
/abc/cab/
abc//sdgf
abc//sdgf/
/abc//sdgf

This should work fine:

var regexString =/^[a-zA-Z]+(\/[a-zA-Z]+)*$/;

And will match

abc
abc/cab
cde/ter/ger

But not

/abc/sucks
abc//text
abc/text/
abc/text//

Here is a regular expression which is going to match a string with parameters you described:

/^([a-zA-Z]+\/[a-zA-Z]+)+$/

Here is an example:

var r = /^([a-zA-Z]+\/[a-zA-Z]+)+$/;
r.test('/ad/sd'); //false
r.test('as//sd'); //false
r.test('as/sd/'); //false
r.test('as/sd'); //true
