如何根据JavaScript中的事件对象获取文件名？

Question

Imagine that an HTML file page1.html has a script tag for base.js . In base.js (ie external JavaScript file), I assign onclick listener to a button that exists in page1.html . Furthermore, base.js is included in script tags across page1.html , page2.html , etc., and each button in each page*?*.html has the same onclick listener assigned to it.

Now, I need to somehow know in the base.js which HTML file invoked the onclick listener, in other words, in which page*?*.html webpage the method was fired. Ideally, I would get the filename of that page*?*.html , where ? could be 1, 2, 3, etc. Is there a way to accomplish that? The code should look like this...

// fires up when a button in 'page*?*.html' is clicked
function myOnClickEventHandler(e) {
    // the file where myOnClickEventHandler originated from is:
    var filename = e.???????
}

Thank you!

var filename = location.href.match(/([^\\/]*?)$/)[1];
