SharePoint 2010 HTML5 and IE9 Compatibility Issues
Saturday, November 24 2012
The downside of this approach is that the solution package may need to be redeployed after upgrades. Many folks will recommend strongly against changing any of the SharePoint files because of supportability and upgrade issues. In this case, I chose this approach and it has worked well for me in several different environments, and it has been usable in production as long as the caveats are understood. More importantly, I wanted to provide a mechanism that allowed continued exploration of HTML5 in SharePoint 2010. This package works for me and I offer it to you “as is”. Use it, change it, recommend modifications, or join the project and contribute your work.
If you choose to deploy this solution to production, you may want to consider “minifying” the libraries (to improve performance and decrease size, at the expense of loss of ease in debugging), and to combine all of the IE9 Fixes into a single library.
At that point, our journey should be complete and hopefully you will be making your own discoveries and sharing them with the rest of our SharePoint community.
