Avoiding duplicate code in javascript

HI,
I have two javascript file as part of a web application which have almost the same function in it. I want to get rid of this duplicacy :

$("#submit").on("click", function(e) {
        var details = utils.getDetails(editor);
        var object = {
            name: $('#title').name(),
            data: editor.getData(),
            msg: $('#msg').val()
        };
        $.ajax({
            contentType: "application/json; charset=utf-8",
            type: "PUT",
            data: JSON.stringify(object),
            success: function(note, status, xhr) {
                  
            },
            error: function(request, status, error) {
                utils.error(text);
            }
        });
    });

Select allOpen in new window

Each js is included in a different page... I want to move these js out to a util.js file and avoid repeating the code here.
Also there are two differences between the javascript code above in the js files :
The other js file differs in the following place :
1)
 success: function(note, status, xhr) {
              lib.close()     // calls this inside the success handler
            },

2) POST //makes a post request

Need help separating out the common part...
Thanks
