lua部分 tips

lua文件刷新

function require_ex( _mname )
    if _mname == "" then
        return
    end
  if package.loaded[_mname] then
  end
  package.loaded[_mname] = nil
  require( _mname )
end

lua字符串分割

function Split(szFullString, szSeparator)  
    local nFindStartIndex = 1  
    local nSplitIndex = 1  
    local nSplitArray = {}  
    while true do  
       local nFindLastIndex = string.find(szFullString, szSeparator, nFindStartIndex)  
       if not nFindLastIndex then  
            nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, string.len(szFullString))  
            break  
       end  
       nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, nFindLastIndex - 1)  
       nFindStartIndex = nFindLastIndex + string.len(szSeparator)  
       nSplitIndex = nSplitIndex + 1  
    end  
    return nSplitArray  
end  

第二种

1. function split(str, reps)  
2.     local resultStrsList = {};  
3.     string.gsub(str, '[^' .. reps ..']+', function(w) table.insert(resultStrsList, w) end );  
4.     return resultStrsList;
5. end 

遍历lua数组

 

方法一，可以用for来遍历：
[cpp] view plaincopy在CODE上查看代码片派生到我的代码片
do  
    table_week = {  
    "w",  
    "e",  
    "r",  
    "t",  
    "y",  
    "u",  
    "i",  
    }  
  
    for i = 1, #table_week do  
        print(table_week[i])  
    end  
end  

#后面接一个数组或者tabe来遍历它，i是该table或者数组的起始下标。
方法2：
[cpp] view plaincopy在CODE上查看代码片派生到我的代码片
do  
    table_week = {  
    "w",  
    "e",  
    "r",  
    "t",  
    "y",  
    "u",  
    "i",  
    }  
    for i, v in pairs(table_week) do  
        print(i)  
    end  
end  

这种是采用迭代器的方式遍历的，i为下标，v为table或者数组的值。

方式3：
[cpp] view plaincopy在CODE上查看代码片派生到我的代码片
do  
    table_week = {  
    "w",  
    "e",  
    "r",  
    "t",  
    "y",  
    "u",  
    "i",  
    }  
    for i in pairs(table_week) do  
        print(i);  
    end  
end  

i为table或者数组的下标。

方式4：
[cpp] view plaincopy在CODE上查看代码片派生到我的代码片
do  
table_view = {  
    "w",  
    "e",  
    "r",  
    color1 = "red",  
    color2 = "blue",  
    {"a1", "a2", "a3"},  
    {"b1", "b2", "b3"},  
    {"c1", "c2", "c3"},  
}  
for i, v in pairs(table_view) do  
    if type(v) == "table" then  
        for new_table_index, new_table_value in pairs(v) do  
            print(new_table_value)  
        end  
    else  
        print(v)  
    end  
end  
  
end  

注：type(v)
功能：返回参数的类型名("nil"，"number", "string", "boolean", "table", "function", "thread", "userdata")
