Fixes bug introduced in c62c2c5.
Test Plan: Tested that the onLoad event was properly triggered on an image. Didn't test onError but I can only assume that it works equally well.
Currently, an `onBlur` creates a new todo on `TodoTextInput`. This makes sense for existing items but not for new items. I.e consider the following:
1. cursor on new item ("What needs to be done?")
2. click 'x' on the first item.
This results in two actions being fired:
1. TODO_CREATE, with an empty string as 'text'
2. TODO_DESTROY
The proposed fix doesn't send a TODO_CREATE if `text.trim() === "")`
I ran into a really difficult-to-debug issue with a React app with SVG
elements. Christopher sat down with me for a while and we finally figured out
that the browser was moving non-SVG elements out of a parent `<svg>` node which
triggered the `processUpdates()` invariant. This updates the error message
thrown from there to include this scenario in the possible issues list.
Fixes#1169.
This is a more robust way of fixing what MobileSafariClickPlugin previously tried to. Now even if you don't want anything to do with touch events, click events still work properly.
Test Plan: Added a click handler to an `<img />` element and triggered it in the iOS simulator -- it didn't execute before.
Not removing them resulted in leaks as we would hold on to removed nodes forever.
This really showed up with images and the load event where we would unmount and create a new img with the same react id as the old one. We properly cleared and primed the caches but we would handle the load event for both nodes. We would eventually hit an invariant in that path as we tried to handle the event for the removed node, which no longer matched the node we had in the cache.
By forcefully removing the listener, we'll avoid this problem entirely and we should leak fewer DOM nodes.
This strategy avoids a runtime check for every set (as opposed to using a mutation method).
Test Plan: Verify that changing className works on a div and a rect in latest Chrome, latest Firefox, IE9. Verify that the div works in IE8.
If the event is on the window object, topScroll, for instance, the topLevelTarget will not have getAttribute defined. Restore the previous `|| !topLevelTarget.attributes` check to avoid an error on every scroll.
I find myself often using (modified) examples to test in IE and it's a pain to have to add the shims in every time. Might as well just add them in always.
