the web browser displays the code itself not the result of it.

I imported a html file into Titanium in app.js using the following code

var webview = Ti.UI.createWebview({
    url: 'D:\files\files\javascriptparser01.html',          // path to the html file.
});

The problem is, when I run the javascriptparser01.html file in the web browser it generates the output. But when I try to run the same file by titanium using the above posted code, the web page(Firefox) displays the code itself not the output of the code.
