The following examples are the results of running the js_who.d script while various JavaScript events happen. A JavaScript program that behaves like a clock is frequently used by these examples, since it can be left running in the background without browser input. Browser input, such as hitting the reload button or using menus, triggers many other JavaScript events since much of the browser uses JavaScript. This makes for interesting longer examples, but would be overwhelming for example #1. In the first example, we can see what happens when we run this program, Code/JavaScript/func_clock.html # js_who.d Tracing... Hit Ctrl-C to end. ^C PID UID FUNCS FILE 10530 100 18 file:///export/home/brendan/Lang/JavaScript/func_clock.html The second example is more complex, the reason for this is that the program Code/Javascript/func_slow.html was loaded in the browser, and the reload button was pressed. This output captured the many browser events that occured when moving the mouse pointer to do so. # js_who.d Tracing... Hit Ctrl-C to end. ^C PID UID FUNCS FILE 10530 100 2 chrome://firebug/content/views/css.js 10530 100 2 chrome://firebug/content/views/dom.js 10530 100 2 chrome://firebug/content/views/events.js 10530 100 2 chrome://firebug/content/views/layout.js 10530 100 2 chrome://firebug/content/views/source.js 10530 100 2 chrome://firebug/content/views/style.js 10530 100 2 chrome://global/content/bindings/scrollbar.xml 10530 100 3 chrome://global/content/bindings/general.xml 10530 100 3 chrome://global/content/bindings/tabbox.xml 10530 100 3 chrome://global/content/bindings/text.xml 10530 100 4 chrome://browser/content/utilityOverlay.js 10530 100 5 chrome://firebug/content/views/view.js 10530 100 6 file:///export/home/brendan/Lang/JavaScript/func_slow.html 10530 100 7 chrome://global/content/bindings/textbox.xml 10530 100 7 chrome://global/content/bindings/tree.xml 10530 100 10 chrome://reporter/content/reporterOverlay.js 10530 100 12 XStringBundle 10530 100 14 chrome://global/content/bindings/progressmeter.xml 10530 100 18 file:///export/home/brendan/Lang/JavaScript/func_clock.html 10530 100 19 chrome://firebug/content/utils.js 10530 100 30 chrome://webdeveloper/content/common/preferences.js 10530 100 43 chrome://global/content/bindings/browser.xml 10530 100 44 chrome://global/content/bindings/tabbrowser.xml 10530 100 72 chrome://global/content/bindings/button.xml 10530 100 88 chrome://global/content/bindings/autocomplete.xml 10530 100 110 chrome://browser/content/browser.js 10530 100 121 chrome://webdeveloper/content/webdeveloper.js 10530 100 133 chrome://firebug/content/firebug.js 10530 100 162 chrome://global/content/globalOverlay.js
