将对象包装成函数

Question

How can I turn this piece of code into a function that accept an element as a parameter for example:

$('#nav-btn li')
                .vel('slideUp', 
                  { 
                    duration: 800, 
                    opacity: 1, 
                    stagger: 150 
                  });

functionName('#nav-btn li');

functionName('#otherElement2');

functionName('#otherElement3');

Answer 1

function functionName(elId){
    $(elId).vel('slideUp', 
                  { 
                    duration: 800, 
                    opacity: 1, 
                    stagger: 150 
                  });
}

Now use

functionName('#nav-btn li');

functionName('#otherElement2');

functionName('#otherElement3');
