Getting outp开发者_JS百科ut like rk-chaitu.I want to split this output using reg expression.

Now my question is how to convert name object to String?

name should already be a string. You can directly use name.split(separator).

EDIT: I see you have added information. Can you post more code? Perhaps the error comes from something else.

The value attribute should already be a String.
