Javascript equivalent to C strncmp (compare string for length) -

-

What is the equivalent function in javascript in strncmp? Strncmp takes two string arguments and an integer length argument. It will be comparable to the length of two strings and determines the length of the distance as far as it was.

Is there a built-in function in Javascript equivalent?

You can easily create this function: 

  function strncmp (Str1, str2, n) {str1 = str1.substring (0, n); Str2 = str2.substring (0, n); Return (str1 == str2)? 0: ((str1> str2)? 1: -1)); }

At the end of the function can be an option for Ternary, such as return str1.localeCompare (str2);

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
