标题: 诡异的循环问题 [打印本页] 作者: zh99998 时间: 2009-2-15 19:13 标题: 诡异的循环问题 Path = ["", "d:\\rpg\\RPG Maker XP\\RGSS\\Standard/"]
ext = ["png", "jpg", ""]
filename = "Graphics/tilesets/001-grassland01"
Path.each do |path|
ext.each do |ext|
filename.insert(0, path)
filename += "." + ext unless ext.empty?
p filename,FileTest.exist?(filename)
return filename if FileTest.exist?(filename)
end
end
只p三次，并且第二行都是false，正常应该是p出4次，第四个是true才对 [LINE]1,#dddddd[/LINE]版务信息：本贴由楼主自主结贴～作者: zh99998 时间: 2009-2-15 19:41

for i in ext
if FileTest.exist?("#{l}#{filename}#{i}")
p ("#{l}#{filename}#{i}")
end
