在具有多个对象的字符串上使用eval

Question

How can I evaluate the following string into multiple objects? at the moment it just does the first then ignores the rest, Ignore the PHP, this is generated via PHP, that being the reason I need to eval it so that I can use it as the options for a jQuery plugin.

            {
                latLng:['.$result->lat.','.$result->lon.'], 
                options:
                {
                    shadow: 
                    {

                        url: "'.BASE_URL.'css/png/markerBg.png",
                        scaledSize: 
                        {
                            width:40,
                            height:43.5
                        }
                    },
                    icon: 
                    {
                        url: "'.$result->user->profileImage.'",
                        scaledSize: 
                        {
                            width:32,
                            height:32
                        },
                        anchor: 
                        {
                            x: 16,
                            y: 40
                        }

                    }

                }

              },

Answer 1

I would avoid doing eval - JSON.parse() is a lot safer. Since it looks like the objects are already comma separated, you should be able to just turn it into an array and parse that. Eg,

var objectArray = JSON.parse('[' + objectString + ']');

Where objectString has the value of what you pasted above. objectArray will now be an array with each of your objects in it.

为此，使用JSON.parse会不会更容易？
