问题 I've always had to put null in the else conditions that don't have anything. Is there anyway around it? E.g. condition ? x = true : null; basically, is there a way to do: condition ? x = true; Now it shows up as a syntax error FYI, here is some real example code: !defaults.slideshowWidth ? defaults.slideshowWidth = obj.find('img').width()+'px' : null; 回答1: First of all, a ternary expression is not a replacement for an if/else construct - its an equivalent to an if/else construct that returns
