问题
i am trying to use sweet alerts in my application its working fine in all browser except IE (version 11).Following errors are coming when i call swal() function.
1.Object doesn't support property or method 'defineProperty'.
2. The value of the property 'swal' is null or undefined, not a Function object
first error is coming from sweetalert.min.js and second is coming from my script where i am calling swal function.
