Javascript Alert message runtime error Object Expected

Question

Ok .. this is a strange one as I have NOT seen this before. I have an application that is strictly a Service ... no browser involved ... and all I want to do is use alert(); for debugging. The only problem is that it causes an Object Expected error even if it is a simple alert("Show me!");

Remember ... this code is not attached to any form or browser. So what am I missing? I thought I could use the alert call at any time in Javascript ... Please folks, help a poor programmer out!

Thank you in advance, Eric

Answer 1

Like praneeth already suggested in his reply, it is a Windows WScript thing, or rather just context in which the script is being run in.

This also works and isn't quite as verbose as what praneeth offered:

WScript.Echo("Hello");

Answer 2

if you are executing this script on a windows machine you can do like this in javascript/Jscript

Var Shell = new ActiveXObject("WScript.Shell"); Shell.Popup("Your Debug message");

Answer 3

The alert() method is one of the JavaScript browser Window object's methods which displays an alert box with a message and an OK button.

The window object represents an open window in a browser. If a document contain frames, the browser creates one window object for the HTML document and one additional window object for each frame.

I believe that in the specified case, the error means that the Window expected object has not been found.

Answer 4

Have you tried window.alert("show me"); ?

Since alert() is a Window object method.

如果你没有在浏览器中运行，那么使用console.log方法可能会更好。再次，如果没有任何关于你正在执行脚本的环境的详细信息，很难告诉你具体做什么。
