Javascript In Ie11 Giving Me Script Error 1003

Solution 1:

The syntax ({nmArray}) in a browser that supports ES6 is a shortcut for {nmArray: nmArray}. IE11 doesn't support this feature (based on the error you're receiving), so you'll have to rewrite it as:

data: ({ nmArray: nmArray }),

See here for an example: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer#New_notations_in_ECMAScript_6

note that in this case you can omit the wrapping ()

data: { nmArray: nmArray },
