如何将参数传递给Event.observe的处理程序？

Question

prototype.js具有以下功能

Event.observe(document, "dom:loaded", foo_function);

在执行document之前等待foo_function完成加载。如何将参数传递给foo_function？

之类的东西

Event.observe(document, "dom:loaded", foo_function, {arg1: bar_argument, arg2: baz_argument})

Answer 1

Event.observe(document, "dom:loaded", (function(e, bar_argument, baz_argument) {
    //now bar_argument = bar,and baz_argument = baz
}).bindAsEventListener(this, bar, baz));
