I have added a pop up box containing another page on my SharePoint site and it works fine in Chrome. When I click the button to open it in IE 10, however, the page just reloads and no pop up box appears. When I look at the page with the developer tools it looks like the function is not even getting called. The block pop ups option is not checked so that is not the problem. Here is the code I am using, any thoughts as to why it wouldn't work in IE?
