Question

I have the following finctions in my script and they do the same thing. How may I combine them?

$('.AddOne').live('click', function(){
    $('.saveGroup').show();
});
$('#PhoneNumbersSelectms2side__sx  option').dblclick(function(){
    $('.saveGroup').show();
});
$('.AddAll').live('click', function(){
    $('.saveGroup').show();
});

Answer 1

The click and dblclick event methods each take a callback function as their first argument. In javascript functions are variables. you create a function, and pass it to the callbacks

var showFn = function(){
    $('.saveGroup').show();
};

$('.AddOne').live('click', showFn);
$('#PhoneNumbersSelectms2side__sx  option').dblclick(showFn);
$('.AddAll').live('click', showFn);

You can further simplify this code by combining the live selectors like this:

$('.AddOne, .AddAll').live('click', showFn);

Finally, if you are using jquery 1.7.x you should use the new on event methods instead of live. Your new code would look like this:

var showFn = function(){
    $('.saveGroup').show();
};
var $doc = $(document);
$doc.on('click', '.AddOne, .AddAll', showFn);
$doc.on('dblclick', '#PhoneNumbersSelectms2side__sx  option', showFn);
