Debugging JavaScript

If you code JS, then you might find this snip of debug code handy. For a given object e (such as event objects in IE or Mozilla), here is how you can see all the properties for that object, including the value of each property:

s = ""
for (propname in e) {
    propval = eval("e." + propname);
    s += propname + "=" + propval + "\n";
}
alert(s);
