The event object is not defined in the dojo.connect function

Following Dojo's documentation, I linked a function using dojo.connect to a dojox.layout.ContentPane:

dojo.connect(cp, 'onHide', function(e) {
    alert('test');
    console.log(e);
});

My assumption was that argument e would contain the triggered event object, but strangely the console output shows undefined. What could be causing this issue?

Answer №1

The answer varies depending on the type of connection you are making.

  • If you are connecting to a DOM event (even though your example does not show this), the DOM event object will be passed into your function.
  • However, if you are connecting to a function within a JavaScript object (as in your example), the arguments passed into the connected function (in this case, onHide) will also be passed into your function. It seems like there may not be any arguments passed into the onHide function.

Please note that dojo.connect has been substituted with dojo/on.
