先看一段简单的代码: local mytable = { , , aa = "abc", subtable = {}, , } --for循环1 print("for --- index") ,#mytable do print(i) end --for循环2 print("for ---- index-value") for i,v in ipairs(mytable) do print(i,v) end --for循环3 print(&quo

new Expectations(){{ calendarService.getGeneralCalendar((Date)any); returns(null, new AbrahamResult<HolidayCalendar>() {{setSuccess(false);}}, new AbrahamResult<HolidayCalendar>() {{setSuccess(true); setResult(holidayCalendar);}}); times =3;}}
先看一个场景 var arr = ["a","b","c"]; for (var i in arr) { $.get("h.html", function (data) {//1 console.log(data); console.log(arr[i]); console.log("----"); })
You call lua_pcall with the number of arguments you are passing and the number of results you want. The fourth argument indicates an error-handling function; we will discuss it in a moment. As in a Lua assignment, lua_pcall adjusts the actual number

标准库提供了集中迭代器,包括迭代文件每行的(io.lines),迭代table元素的(pairs),迭代数组元素的(ipairs),迭代字符串中单词的 (string.gmatch)等等.LUA手册中对与pairs,ipairs解释如下: ipairs (t) Returns three values: an iterator function, the table t, and 0, so that the construction for i,v in ipairs(t) do body e
