Ways to retrieve a JSON value with JavaScript

Take a look at this JSON document:

[  
       {  
          "title":"Potato and Cheese Frittata",
          "href":"http://allrecipes.com/Recipe/Potato-and-Cheese-Frittata/Detail.aspx",
          "ingredients":"cheddar cheese, eggs, olive oil, onions, potato, salt",
          "thumbnail":"http://img.recipepuppy.com/2.jpg"
       },
       {  
          "title":"Eggnog Thumbprints",
          "href":"http://allrecipes.com/Recipe/Eggnog-Thumbprints/Detail.aspx",
          "ingredients":"brown sugar, butter, butter, powdered sugar, eggs, flour, nutmeg, rum, salt, vanilla extract, sugar",
          "thumbnail":"http://img.recipepuppy.com/3.jpg"
       },
       {  
          "title":"Irish Champ",
          "href":"http://allrecipes.com/Recipe/Irish-Champ/Detail.aspx",
          "ingredients":"black pepper, butter, green onion, milk, potato, salt",
          "thumbnail":"http://img.recipepuppy.com/5.jpg"
       },
       {  
          "title":"Chocolate-Cherry Thumbprints",
          "href":"http://allrecipes.com/Recipe/Chocolate-Cherry-Thumbprints/Detail.aspx",
          "ingredients":"cocoa powder, baking powder, butter, eggs, flour, oats, salt, sugar, vanilla extract",
          "thumbnail":"http://img.recipepuppy.com/6.jpg"
       },
       {  
          "title":"Hot Spiced Cider",
          "href":"http://allrecipes.com/Recipe/Hot-Spiced-Cider/Detail.aspx",
          "ingredients":"allspice, apple cider, brown sugar, cinnamon, cloves, nutmeg, orange, salt",
          "thumbnail":"http://img.recipepuppy.com/8.jpg"
       }
    ]

I'm trying to extract only the titles for each result. For example, from this data I want to retrieve (Potato and Cheese Frittata, Eggnog Thumbprints, Chocolate-Cherry Thumbprints, Hot Spiced Cider).

Your assistance is greatly appreciated!

Answer 1

Answer №1

JSFiddle Example

JSON, a string notation for serializing data, can be parsed in JavaScript to create objects or arrays. In this case, the data is already deserialized into an array of objects.

To extract just the titles from these objects, you can use the built-in .map^MDN method.

var titles = result.map(function(obj){ return obj.title; });
