“Uncaught TypeError: Cannot use 'in' operator to search for 'length' in ” triggered by Datatables plugin and jQuery 1.11.3

Question

I\'m using the jQuery Datatables plugin to enable pagination, sorting and searching with my tables. The elements are showing up but not working, and the pagination only sometime

Answer 1

That error is because of the method isArraylike in jQuery version 1.11.3. (only). The method looks like this

function isArraylike( obj ) {

    // Support: iOS 8.2 (not reproducible in simulator)
    // `in` check used to prevent JIT error (gh-2145)
    // hasOwn isn't used here due to false negatives
    // regarding Nodelist length in IE
    var length = "length" in obj && obj.length, // <------ THIS IS THE CULPRIT
        type = jQuery.type( obj );

    .......
}

That version of jQuery was using "length" in object to get the length. (I do not know anything about it).

But I do know that no other versions of jquery have that issue.

The versions 1.11.3 and 2.1.4 (as James pointed out in the comments) have this issue.

So the solution would be to just upgrade to the next version or at least use any other version apart from 1.11.3 or 2.1.4
