How can Lua determine if this text exists?
In Lua, you can use the string.find function to determine if a string contains a specific text. This function will return the position of the text’s first occurrence in the string, or nil if it is not found.
Below is a sample code:
local str = "Hello, Lua!"
if string.find(str, "Lua") then
print("字符串中包含Lua")
else
print("字符串中不包含Lua")
end
The output shows that the string contains Lua.
