遍历JSON数据以生成HTML [英] Looping through JSON Data to Generate HTML

问题描述

我有如下所示的JSON数据:

I have JSON data that looks like this:

data = {
  "tennis": [{
    "Description": "Insert description here.",
    "Price": 379.99,
    "ProductName": "Babolat Play Pure Drive",
  }, {
    "Description": "Insert description here.",
    "Price": 199.99,
    "ProductName": "Yonex AI 98 Tennis Racquet",
  }],
  "basketball": [{
    "Description": "Insert description here.",
    "Price": 64.99,
    "ProductName": "Wilson NCAA Solution Official Game Basketball",
  }, {
    "Description": "Insert description here.",
    "Price": 59.99,
    "ProductName": "Spalding NBA NeverFlat Size 7 Composite Leather Basketball",
  }]
}

我正在使用此数据生成HTML，因此它的格式正确，易于用户阅读.我这样做的方法是创建一个for循环以阅读网球和篮球类别.例如:

I am using this data to generate HTML so it looks properly formatted and easily readable for the user. The way I am doing this is by creating a for loop to read through tennis and basketball categories. For example:

for (var i = 0; i < data.tennis.length; i++) {
  tennisProducts.push(data.tennis[i]);
  var tennisProductsTitle = tennisProducts[i].ProductName;
  var tennisProductsDescription = tennisProducts[i].Description;
  var tennisProductsPrice = tennisProducts[i].Price;
  var badge = document.createElement('div');
  badge.className = 'badge';
  badge.innerHTML =
    '<h1>' + tennisProductsTitle + '</h1>' +
    '<h2>' + tennisProductsDescription + '</h1>' +
    '<div class="options-only-phone">' +
    '<a class="service-provider-call" href="#" target="_blank"> Buy for $' + tennisProductsPrice + '</a>';
  document.getElementById('tennis-products-list').appendChild(badge);
}

如何创建一个可以读取两个(或多个)类别的for循环?

How can I create one for loop that can read through both (or multiple) categories?

推荐答案

双循环，一个循环对象的属性，另一个循环数组:

Double loop, one to iterate the object properties, the next to iterate the array:

for (var key in data) {
    for (var i = 0; i < data[key].length; i++) {
        //HTML logic
    }
}

最终代码:

for (var key in data) {
    for (var i = 0; i < data[key].length; i++) {
        var title = data[key][i].ProductName;
        var desc = data[key][i].Description;
        var price = data[key][i].Price;
        var badge = document.createElement('div');
        badge.className = 'badge';
        badge.innerHTML =
            '<h1>' + title + '</h1>' +
            '<h2>' + desc + '</h1>' +
            '<div class="options-only-phone">' +
            '<a class="service-provider-call" href="#" target="_blank"> Buy for $' + price + '</a>';
        //I gave the div the same ID's as the keys in the object for ease
        document.getElementById(key).appendChild(badge);
    }
}
