How to fix   Complexity   

Complexity

Complex classes like www/assets/js/jquery-ui.min.js often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes.

Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.

Bug introduced by
The variable define seems to be never declared. If this is a global, consider adding a /** global: define */ comment.

This checks looks for references to variables that have not been declared. This is most likey a typographical error or a variable has been renamed.

To learn more about declaring variables in Javascript, see the MDN.

Curly braces around statements make for more readable code and help prevent bugs when you add further statements.

Consider adding curly braces around all statements when they are executed conditionally. This is optional if there is only one statement, but leaving them out can lead to unexpected behaviour if another statement is added later.

Consider:

if (a > 0)
    b = 42;

If you or someone else later decides to put another statement in, only the first statement will be executed.

if (a > 0)
    console.log("a > 0");
    b = 42;

In this case the statement b = 42 will always be executed, while the logging statement will be executed conditionally.

if (a > 0) {
    console.log("a > 0");
    b = 42;
}

ensures that the proper code will be executed conditionally no matter how many statements are added or removed.

There is no return statement in this branch, but you do return something in other branches. Did you maybe miss it? If you do not want to return anything, consider adding return undefined; explicitly.

Comprehensibility Best Practice introduced by
Are you sure this return statement is not missing an argument? If this is intended, consider adding an explicit undefined like return undefined;.

Consider using undefined instead of void(0). It is equivalent and more straightforward to read.

Comprehensibility introduced by
Usage of the sequence operator is discouraged, since it may lead to obfuscated code.

The sequence or comma operator allows the inclusion of multiple expressions where only is permitted. The result of the sequence is the value of the last expression.

This operator is most often used in for statements.

Used in another places it can make code hard to read, especially when people do not realize it even exists as a seperate operator.

This check looks for usage of the sequence operator in locations where it is not necessary and could be replaced by a series of expressions or statements.

var a,b,c;

a = 1, b = 1,  c= 3;

could just as well be written as:

var a,b,c;

a = 1;
b = 1;
c = 3;

To learn more about the sequence operator, please refer to the MDN.

Comparing null to n = i.o using the != operator is not safe. Consider using !== instead.

There is no return statement if !this._handlePageNav(e) is false. Are you sure this is correct? If so, consider adding return; explicitly.

This check looks for functions where a return statement is found in some execution paths, but not in all.

Consider this little piece of code

function isBig(a) {
    if (a > 5000) {
        return "yes";
    }
}

console.log(isBig(5001)); //returns yes
console.log(isBig(42)); //returns undefined

The function isBig will only return a specific value when its parameter is bigger than 5000. In any other case, it will implicitly return undefined.

This behaviour may not be what you had intended. In any case, you can add a return undefined to the other execution path to make the return value explicit.

You seem to be assigning a new value to the loop variable s here. Please check if this was indeed your intention. Even if it was, consider using another kind of loop instead.
