Recently in a client program, using the WebBrowser control, when JS call window.open () or a tag target= "_blank" when using the pop-up IE window, do not know why this design, simply do not meet the needs of it. On the Internet to check the relevant information, found that the control does not have properties to control this function, so find a third-party

Semantically it can be used, and other languages are not worse, just remember, one of the furthest distances in the world: I walk if you go else.2, according to individual years of programming experience, too many if...else ... Nesting increases the readability and difficulty of maintaining code. Personally think the code is best not more than three layers if...else ... Nested, otherwise it is best to use a Boolean control
