How does JSL call google's web translation results?

[#1]

For example, how do I translate the specified English content into Chinese?
This is the result of a GPT3.5 query and does not work.

Thanks!

url = "https://translate.google.com";
sourceText = "Hello, world!";
targetLanguage = "zh-CN";  // Chinese Simplified

// Build the HTTP request
postData = "sl=en&tl=" || urlEncode(targetLanguage) || "&text=" || urlEncode(sourceText);
headers = Associative Array("Content-Type", "application/x-www-form-urlencoded", "User-Agent", "Mozilla/5.0");

httpReq = New HTTP Request(
    url,
    "POST",
    headers,
    postData
);

// Send the HTTP request and retrieve the response
httpReq.Send();
response = httpReq.ResponseBody();

// Extract the translation
startPos = Pos(response, "<span title=\"") + Length("<span title=\"");
endPos = Pos(response, "\">", startPos);
translation = Substr(response, startPos, endPos - startPos);

// Display the translation result
Show("Source Text: " || sourceText);
Show("Translation: " || translation);

There are many many incorrect functions used in your example. I would first use scripting index to fix those and then get back here if needed.
