【IT168 技术文档】这是一个更简洁的迭代字符串的方法.
for color in string.gfind("red green blue black orange green", "[^ ]+") do ChatFrame1:AddMessage('My favorite color is ' .. color .. '.'); end
第二个参数以 '^' 开头的是分隔符. 这里表示非空白, 你可以使用分隔符 '\n' 来迭代多行的长字符串.
HELP_MESSAGE = [[ This is the first line of help to show. And here is the second. And here is the third. Let's make sure to include enough text to bore the user. ]]; for line in string.gfind(HELP_MESSAGE, '[^\n]+') do ChatFrame1:AddMessage(line); end
