I’ve tried removing the <script> tags. I find that this…
var name =“Chris”;
…produces no error, but doesn’t do anything either. Anytime I try to use the alert() function, I get an error. I’ve tried using both “JScript” and “JavaScript” as the value for the language attribute.
If I do that, then it will open a browser when I run it. I’m trying to get it to bring up an alert or prompt or something when I execute it. I’m not stupid. Obviously changing it to a .html file will get the JS to run, just not in the way I want.
Seeing as how it gives me a JScript error message, I’m led to believe that I can get this to work, if I simply find out how Windows wants this thing laid out.
And then make sure the js file itself contains no <script> tags, just pure JavaScript.
If that doesn’t work, then it seems like it has to be something in the js file itself. Although if you’re just setting a var and doing an alert on it, there’s not much that can go wrong.
If it’s still broken, post some code or give us an URL.
I really don’t want to offend anyone here, but it seems that both people who have responded are not really understanding what it is I’m trying to do. I have no problem at all running JavaScript from an HTML file – either embedded, or externally.
What I’m trying to do is allow myself to execute a .js file directly and have that JS process – when I try to “output” anything, IE: print to the screen or call on the alert() function, I get a JScript error (not JavaScript, JScript).
The idea is to have a link to a .js file on my QuickLaunch bar or something. I was hoping to write a JavaScript to provide me with a menu or something – but that’s irrelevant anyway.
As for code/the error: I posted exactly what I got. There really isn’t any more than that.
You must execute a js file through a browser. Unless you have some other special program that noone has written that will run js locally. You have to have something to interpret the js, and for 99% of the population, this is done with their favorite web browser.
I thought the same thing myself originally, but why would I receive a JScript error if this is the case? That implies that I can run something, but that what I ran caused an error.
Yes, the browser runs the above JS without problem. I see your point, but getting a JScript error leads me to believe there’s got to be some way to do this.
The fact that it gave me an error must mean I have something somewhere that interprets this. Maybe no one around here knows, but I’d be very surprised if there was not a way to modify the code to work.
If you try to execute a .js file locally, the Windows Scripting Host calls the appropriate scripting engine to handle the script. It interprets js files as JScript, NOT JavaScript. ‘alert’ is not a function in JScript.
You can get an alert to display in JScript, but it involves writing a function to do it, not just simply using ‘alert.’
Below is some JScript for an alert. Put this in your js file and watch the magic happen.
var vbOKCancel = 1;
var vbInformation = 64;
var vbCancel = 2;
var L_Welcome_MsgBox_Message_Text = "This is my message.";
var L_Welcome_MsgBox_Title_Text = "My Alert Box";
Welcome();
function Welcome() {
var WSHShell = WScript.CreateObject("WScript.Shell");
var intDoIt;
intDoIt = WSHShell.Popup(L_Welcome_MsgBox_Message_Text,
0,
L_Welcome_MsgBox_Title_Text,
vbOKCancel + vbInformation );
if (intDoIt == vbCancel) {
WScript.Quit();
}
}
So if you want to do actions outside of the browser, JScript is an option, but it’s a whole different ball game from JavaScript.
