To retrieve the content of an input field in Lua, you can follow these steps:

  1. Firstly, create a text box object using a GUI library.
  2. Next, utilize the relevant methods of the text editing object to retrieve the content.

Here is an example:

-- 引入GUI库
local gui = require("gui")

-- 创建一个窗口
local window = gui.createWindow("My Window", 400, 300)

-- 创建一个编辑框
local editBox = window:createEditBox("My EditBox", 100, 100, 200, 30)

-- 创建一个按钮
local button = window:createButton("Get Content", 150, 150, 100, 30)
button.onClick = function()
  -- 获取编辑框的内容
  local content = editBox:getText()
  print("EditBox content: " .. content)
end

-- 运行GUI循环
gui.run()

In the example above, a window object is first created using the gui.createWindow method. Then an edit box object is created using the createEditBox method of the window object. Next, the getText method of the edit box object is used to retrieve the content of the edit box and print it out. Finally, the gui.run method is used to run the GUI loop, allowing the window and buttons to respond to user actions.

Please note that the GUI library and methods mentioned in the code above are just examples. The actual GUI library and methods you use may be different. You should refer to the documentation and examples of the GUI library you are using to retrieve the content of the text box.
