Strange behavior of Google Chrome 6

Question

Google Chrome

There is a piece of code. Inside some function. In FF3 both messages are the same and expected. In Chrome 6, the second message returns null. Who knows why?

_ondblclick = 'some_function();';
ondblclick = 'some_function();';

alert(_ondblclick);
alert(ondblclick);


Answer 1

Apparently, Chrome does not allow writing to the global scope (which is essentially window) variables that have event handler attribute names.
In a different scope, what is needed alerts.
