[英]Can you have a doubly nested object literal?
Can I have a doubly nested object literal like the value of "ingredients" below (is the syntax correct)? 我可以像下面的“ ingredients”的值那样使用双重嵌套的对象常量吗(语法正确)吗?
recipes = [
{name: 'Zucchini Muffins', url: 'pdfs/recipes/Zucchini Muffins.pdf',
ingredients: [{name: 'carrot', amount: 13, unit: 'oz' },
{name: 'Zucchini', amount: 3, unit: 'sticks'}]
}
];
and if so, how would I access the "unit" value of the "ingredients" objects? 如果是这样,我将如何访问“成分”对象的“单位”值?
Could i do something like this? 我可以做这样的事情吗?
psuedocode 伪码
for each recipes as recipe
print "this recipe requires"
for each recipe.ingredients as ingredients
ingredients.amount + " " + ingredients.unit;
(I'm thinking of using javascript) (我正在考虑使用JavaScript)
This is how you can get all the infos you need from this array( here is a jsfiddle ): 这是您可以从此数组( 这是jsfiddle )中获取所需所有信息的方法 :
function printRecipes(recipeList) {
for(var i = 0; i < recipeList.length; i++) { //loop through all recipes
var recipe = recipeList[0], //get current recipe
ingredients = recipe.ingredients; //get all ingredients
console.log("This recipe is named", recipe.name, "and can be accessed via", recipe.url);
console.log("These are the ingredients:");
for(var j = 0; j < ingredients.length; j++) { //loop through all ingredients of current recipe
var ingredient = ingredients[j]; //get current ingredient
console.log("You need", ingredient.amount, ingredient.name + "(s)", "mesured in", ingredient.unit);
}
console.log("Finished recipe", name + "'s", "ingredient list, passing to next recipe!");
}
}
