Function splitWithForm

core/base/NS.cpp:62–98

first, judge whether the form of the string like this: {x,y} if the form is right,the string will be split into the parameter strs; or the parameter strs will be empty. if the form is right return true,else return false.

// or the parameter strs will be empty.
// if the form is right return true,else return false.
