what is wrong with this code because it did not work?

if (typeof ActiveXObject !== "undefined") {
var adoconn = New ActiveXobject("ADODB.Connection");
var adors = New ActiveXObject("ADODB.Recordset");
adoconn.open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source ='/\book.mdb'");
adors.open("beginner",adoconn,1,3);
var str = adors.fields("questions").value;
window.alert(str)
}

Code (markup):

 

THIS. Not only that, but it only ever worked in Internet Explorer which... well... it's 2023, who the blazes is still using IE? And even in IE it started being disabled by default as a security flaw sometime around 2007.

 

Have AI (like ChatGPT or Google Bard) write the code for you and compare to yours. I'll bet you'll find the error .

 

The code might have compatibility issues (for older browsers) or syntax errors. Check the file path and for typos (especially capitalization).

 

Here’s the corrected JavaScript code:



if (typeof ActiveXObject !== "undefined") {
var adoconn = new ActiveXObject("ADODB.Connection");
var adors = new ActiveXObject("ADODB.Recordset");
adoconn.open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source='\\\\book.mdb'");
adors.open("beginner", adoconn, 1, 3);
var str = adors.fields("questions").value;
console.log(str);
} else {
console.log("ActiveXObject is not available in this environment.");
}

 

The code you provided has a couple of issues that would prevent it from working in modern environments:

1. ActiveXObject Deprecation: The primary issue is the use of ActiveXObject. ActiveXObject is an Internet Explorer (IE) specific way to create objects. It's not supported in modern browsers and has been deprecated for a long time.
   
   
2. Syntax Error: There's a minor syntax error in the first line where it says New ActiveXobject instead of new ActiveXObject (lowercase 'n').
   

Here's a breakdown of the limitations:

• Non-functional in most browsers: Since ActiveXObject is specific to IE, the code wouldn't work in other browsers like Firefox, Chrome, or Safari.
• Security Concerns: ActiveX has security vulnerabilities and is generally discouraged in modern development.

If you're aiming for broader browser compatibility, you'll need to abandon ActiveX and explore alternative approaches for database access or data manipulation depending on your goal.

Here are some possible alternatives depending on your scenario:

• Web APIs: If you're working with a web application and need to access data from a server-side database, consider using Web APIs like REST or GraphQL. These provide a standardized way to communicate with a server and retrieve data.
• IndexedDB: If you're working with a client-side application and need to store data locally in the browser, you can explore IndexedDB, a browser API for storing data on the client-side.
