Question

如何将此JSON文件中的数组列出到表中？我可以有单个值，如标题出现查找，但当我尝试调用result.ingredients [index]我得到undefined？香港专业教育学院尝试过result.recipe.ingredients [index]，但它仍未定义，并且我在网上找到的关于如何做到这一点很少？

var result = [];


$.ajax({
    url: 'https://community-food2fork.p.mashape.com/get?key=0ee5a01caf7f7c3512b54978628f1a4e&rId=37859', // The URL to the API. You can get this in the API page of the API you intend to consume
    type: 'GET', // The HTTP Method, can be GET POST PUT DELETE etc
    data: {}, // Additional parameters here
    dataType: 'json',
    success: function(data) { 
        result = JSON.parse(JSON.stringify(data.recipe));
        console.dir(result.ingredients);
        $('#location').append($.map(result, function (ignore, index) {
            return '<tr><td>' + result.title+ '</td><td>' + result.ingredients[index] + '</td></tr>';
        }).join());
    },
    error: function(err) { alert(err); },
    beforeSend: function(xhr) {
        xhr.setRequestHeader("X-Mashape-Authorization", "KEY"); // Enter here your Mashape key
    }
});

JSON：

如果您试图遍历各个成分并列出它们，则可能需要简单的每个循环

编辑：使用每个

success: function(result) {                           
  var msg;
  $.each(result.ingredients, function (key, ingredient) {
        msg = msg+ '<tr><td>' + result.title+ '</td><td>' + ingredient + '</td></tr>';
  }));
  $('#location').append(msg);      
}

使用地图

success: function(result) {                           
  var msg = 
  $.map(result.ingredients, function (ingredient, index) {
        return '<tr><td>' + result.title+ '</td><td>' + ingredient + '</td></tr>';
  }).join();
  $('#location').append(msg);      
}
