Question

最近我一直试图添加一个基本单词。我想这样做，所以你点击文本字段然后你键入你需要的然后它将它写入.txt文件（precreated与否）我不是很好的编码和我努力使用样本/其他人Stack Exchange要学习的问题。我所拥有的只是一些不能协同工作的代码，我不知道我需要做些什么来使它们工作（代码不是我的）

local textBox = native.newTextBox( 200, 200, 280, 140 )
textBox.text = "This is line 1.\nAnd this is line2"
textBox.isEditable = true


local file = io.open( filePath, "r" )
if file then
-- read all contents of file into a string
local contents = file:read( "*a" )

print( "Contents of " .. filePath )
print( contents )

io.close( file ) -- Important to close (python knowledge)

local t = display.newText( "Contents of ", 5, 80, nil, 16 ); -- w, h, ?, size
t:setFillColor( 1, 1, 135/255 ); -- edit
local t = display.newText( filePath, 5, 100, nil, 10 );
t:setFillColor( 1, 1, 135/255 );

local ylast = 130 -- how far down the Y value it can make words on the screen
for line in io.lines(filePath) do
    local t = display.newText ( line, 15, ylast, nil, 14); -- dont understand
    t:setFillColor( 1, 1, 1 );
    ylast = ylast + 20
    end
end

local function inputListener( event )
if event.phase == "began" then

    -- user begins editing textBox
    print( event.text )

elseif event.phase == "ended" then
    textBox.text = event.text
    local path = system.pathForFile( "myfile.txt", system.DocumentsDirectory )

    local file = io.open( path, "w" )
    file:write( textBox.text )
    io.close( file )
    file = nil 

elseif event.phase == "editing" then

    print( event.newCharacters )
    print( event.oldText )
    print( event.startPosition )
    print( event.text )

end
end

textBox:addEventListener( "userInput", inputListener )

我建议使用loadsave函数，这样可以更轻松。

您可以从此处下载这些功能。

https://github.com/robmiracle/Simple-Table-Load-Save-Functions-for-Corona-SDK

下载后，只需将loadsave.lua文件放入主项目文件夹即可。

现在你可以像这样使用它。

示例：

local loadsave = require("loadsave")   

local tableToSave = {}

-- load text into a table
tableToSave ['saved-text'] = textYouWantToSave

-- save text
loadsave.saveTable(tableToSave, "filename.json")

local savedTable = {}

-- load text
savedTable = loadsave.loadTable("filename.json")

-- text is stored here
savedTable['saved-text']

从TextBox Lua写入文件
