In Ie7

I tried a few simple jQuery manipulation on //

Solution 1:

The button tag isn't fully supported on IE6 and IE7. It isn't related to jQuery, but about the tag itself, as described here: What disadvantages are there to the <button> tag?.

Solution 2:

I don't see a method named .innerWrap() in jQuery. I see one named .wrapInner(). If I switch your code to .wrapInner(), it works for me in this jsFiddle in IE9 and in IE9 in IE8 and IE7 emulation mode. I don't have the actual IE7 available to try here, so perhaps part of the issue is the partial support in IE7 for the button tag.
