【问题描述】：
我正在尝试将来自 Google 购物的 JSON 响应加载到使用 JQuery 插件 DataTables 格式化的 html 表格中。
我正在将数据附加到表格 div 中，但它似乎不起作用。
<table cellpadding="0" cellspacing="0" border="0" class="display" id="example">
<thead>
<tr>
<th>ID</th>
<th>Title</th>
<th>Currency</th>
<th>Price</th>
<th>Shipping</th>
</tr>
</thead>
<tbody>
</tbody>
<tfoot>
<tr>
<th>ID</th>
<th>Title</th>
<th>Currency</th>
<th>Price</th>
<th>Shipping</th>
</tr>
</tfoot>
</table>
<script>
var apiKey = "key";
var country = "US";
var apiurl = "https://www.googleapis.com/shopping/search/v1/public/products?callback=?";
$(document).ready(function() {
$('#example').dataTable();
$('.button').click(function (e) {
$('#example').empty();
e.preventDefault();
$.ajax({
type: "GET",
url: apiurl,
dataType: 'jsonp',
data :
{
key: apiKey,
country: country,
q: $('[name=myanswer]').val()
},
success: function(data) {
$.each(data.items, function(i, item){
if (item.product.images.length > 0) // sanity check
{
//global variables
var link = item.product.images[0]['link'];
var title = item.product.title;
var gtin = item.product.gtins[0];
//price
var currency = item.product.inventories[0]['currency'];
var price = item.product.inventories[0]['price'];
var shipping = item.product.inventories[0]['shipping'];
var listData = "<li>" + title + gtin + price + currency + shipping + "</li>" + '<img title="' + title + '" src="' + link + '" />';
var dataTable =
"<tr>" +
"<td>" + '<img title="' + title + '" src="' + link + '" />' + "</td>" +
"<td>" + gtin + "</td>" +
"<td>" + title + "</td>" +
"<td>" + currency + "</td>" +
"<td>" + price + "</td>" +
"<td>" + shipping + "</td>" +
"</tr>";
$('#example').append(dataTable).hide().fadeIn('slow');
console.log(data)
}
});
}
});
});
});
更新：在拉里的帮助下，我设法将数据加载到表中。我知道这一点，因为底部的数字已填充。但是，数据根本不显示。

已修复。我忘了删除强制表格显示为空的空方法
