jQuery对象文字函数声明错误

Question

I am wondering what is wrong with this code, it throws a Syntax Error: unexpected token "anotherFuction if I add the anotherFunction part. Can someone please explain why, JavaScript is confusing me so much with all this different ways calling functions.

var ajax = {

        parseJSONP : function(result) {
            console.log(result)

            //iterate each returned item
            $.each(result.items, function(i, row) {
                $('#listview_test').append('<li><a href="#headline"><img src="' + row.volumeInfo.imageLinks.thumbnail + '" class="ui-li-has-thumb"/><h3>' + row.volumeInfo.title + '</h3></a></li>');
            });
            //end iteration of data returned from server and append to the list
            $('#listview_test').listview('refresh');
            // refresh the list-view so new elements are added to the DOM
        }

        //error is here, I just wanted to add another function here to do 
         something

        anotherFuction : function(){

        }
    }
}

Answer 1

You're forgetting the , after the closing } of the first member in the object literal.

You need to separate each member, as shown below:

var ajax = {    
        parseJSONP : function(result) {
            $.each(result.items, function(i, row) {
                $('#listview_test').append('<li><a href="#headline"><img src="' + row.volumeInfo.imageLinks.thumbnail + '" class="ui-li-has-thumb"/><h3>' + row.volumeInfo.title + '</h3></a></li>');
            });
            $('#listview_test').listview('refresh');
        },
      // ^ Here   
       anotherFuction : function(){
           // No more syntax errors!
       }   
}

Answer 2

When you use the "Object Literal Syntax", eg:

var object = {};

You have to separate all "members" (variables, functions) with a comma ( , ).

So your code will become:

var ajax = {
   parseJSONP: function(result) { /* function body from above */ },
   something,
   anotherFunction: function() {}
}

notice the addition of the commas ( , ) after something and parseJSONP .
