1. 将字符串分割成一个一个单元,存在表中

  • 代码如下:
      local s = "sofgs啊等级高5584撒旦法规"
      local tb = {}
      for utfChar in string.gmatch(s, "[%z1-127194-244][128-191]*") do  
          table.insert(tb, utfChar)  
      end
    

    – 如果要提取出字符串中的数字
    local s1 = ""
    local s2 = ""
    for k,v in pairs(tb) do
    local n = tonumber(v)
    if n then
    s1 = s1v
    else
    s2 = s2v
    end
    end


2. 删除table中重复的值

  • 代码如下:
      function unique(t, bArray)  
          local check = {}  
          local n = {}  
          local idx = 1  
          for k, v in pairs(t) do  
              if not check[v] then  
                  if bArray then  
                      n[idx] = v  
                      idx = idx + 1  
                  else  
                      n[k] = v  
                  end  
                  check[v] = true  
              end  
          end  
          return n  
      end 
    

3. 判断一个table是否是另一个table的子集或相同

  • 代码如下:
      local A = {33,24,11}
      local B = {24,50,33,12,11}
      local C ={}
      local isExistTable = {}
      for i=1,#A do
          table.insert(isExistTable,false)
      end
      for k1,v1 in pairs(A) do
          for k2,v2 in pairs(B) do
              if v1 == v2 then
                  isExistTable[k1] = true                       
              end
          end
      end
      local isAdd = true
      for i,v in ipairs(isExistTable) do
          if v == false then
              isAdd = false
          end
      end
      if isAdd then
          table.insert(C,B)
      end
