Simple Modal, jQuery 1.8.0 and IE9
jquery, simplemodal
Solution
It appears that the issue can be resolved by changing $.boxModel to $.support.boxModel. You can grab an updated version at http://github.com/ericmmartin/simplemodal.
I will try and get a fully packaged release, with min version, out shortly.
[edit] SimpleModal 1.4.3 has been released and should resolve this issue
Problem
Simple Modal fails with jQuery 1.8.0 and IE9 with the error: SCRIPT438: Object doesn't support property or method 'removeExpression' The following fiddle demonstrates (remember to run with IE9) http://jsfiddle.net/ericjohannsen/ZVEWa/1/ Switching jQuery to 1.7.2 causes the error to go away. Is there a way to work around this?
