moment.js错误“不支持indexOf”

Question

I have downloaded the latest version of moment.js and tried this example from their website in my code:

alert(moment().subtract(10, 'days').calendar());

I get a message that the property or method IndexOf is not supported by this object.

I'm using Internet Explorer 11.

How can I solve this?

Thanks for the responses. This was helpfull. Turned out that this line was in the way:

I deleted this line and it worked.
