输入框组件字符校验

-- 限制输入字符为字母数字
local re = "[%w]*"
-- 获取输入框组件
local testInputField = GameObject.Find("testInputField")
testInputField:GetComponent("InputField").onValueChanged:AddListener(function(text)
    local inputText = ""
    for v in string.gmatch(text, re) do
        inputText = inputText..v
    end
    testInputField:GetComponent("InputField").text = inputText
end)
