Tooltip Widget breaks in IE

Reported by: youngjl1 Owned by: youngjl1
Priority: minor Milestone: none
Component: ui.widget Version: 1.10.1
Keywords: Cc:
Blocked by: Blocking:

jQuery Version: 1.9.1

jQuery-UI Version: 1.9.2

Browser: IE8

OS: Windows

Steps to see what I'm talking about:

1. Go here in chrome:

2. Pull up Chrome Dev Tools -> Sources -> Open jquery-ui.js

3. Add a break point on line 842 where it says

  • hasOptions = !$.isEmptyObject( options );

4. Hover over where it says "Some text"

5. The code should stop at the break point, check the value of options. It is true.

Now, according to the documention of $.isEmptyObject (

The argument should always be a plain JavaScript Object as other types of object

(DOM elements, primitive strings/numbers, host objects) may not give consistent

results across browsers.

The boolean value of true is definitely not a plain JS Object and this actually does cause issues in IE. To see:

1. Go to in Internet Explorer 8

2. Pull up dev tools

3. Switch Browser Mode to "IE8 Compat View"

4. Switch Document Mode to "IE7 Standards"

5. Switch to Script tab

6. run the following script: true.toJSON()

running that script returns true because for some unknown reason the boolean value true has a method associated with it. In this weird case calling $.isEmptyObject(true) will actually return false when for any other browser it would return true, and in this case the widget will break.

Sorry I was unable to give straight-forward directions to reproduce this. This is the first time I've logged a jquery bug.

Basically the widget shouldn't be passing a primitive boolean into $.isEmptyObject. It goes against the documentation of that method and in some cases with IE the widget will break.

I'm not seeing any errors in that jsFiddle example using IE 8. Your description doesn't sound like you're able to reproduce this either. I understand the technical point you're making about $.isEmptyObject(), but I cannot reproduce the bug you're trying to report.

You're able to use jsFiddle with IE 8? I get js errors trying to go to that site.

Use to just load the output.

I've researched this some more and determined that the problem I was experiencing was not with the jQuery UI. Please close this bug.
