使用您擁有的數據,創建一個數據結構,以幫助您在構建表之前構建表。
假設我們有以下數據
var data = [{
email_address: '[email protected]',
number_of_ordrs: 4,
total_order_value: 5.56
}, {
email_address: '[email protected]',
number_of_orders: 3,
total_order_value: 8.97
}, {
email_address: '[email protected]',
number_of_orders: 6,
total_order_value: 0.93
}, {
email_address: '[email protected]',
number_of_orders: 6,
total_order_value: 0.93
}];
讓我們改變它,使它看起來像
var newData: {
'able.com': [{
email_address: '[email protected]',
number_of_orders: 4,
total_order_value: 5.56
}, {
email_address: '[email protected]',
number_of_orders: 6,
total_order_value: 0.93
}],
'bodge.com': [{
email_address: '[email protected]',
number_of_orders: 3,
total_order_value: 8.97
}, {
email_address: '[email protected]',
number_of_orders: 6,
total_order_value: 0.93
}]
};
我們還需要另一個變量domains
,一個陣列,存儲和域排序。在JavaScript中,order of the properties is not guaranteed,因此迭代對象不是一個好主意。相反,我們將使用domains
來確保訂單。
$(function() {
var data = [{
email_address: '[email protected]',
number_of_orders: 4,
total_order_value: 5.56
}, {
email_address: '[email protected]',
number_of_orders: 3,
total_order_value: 8.97
}, {
email_address: '[email protected]',
number_of_orders: 6,
total_order_value: 0.93
}, {
email_address: '[email protected]',
number_of_orders: 6,
total_order_value: 0.93
}];
var newData = {};
data.forEach(function(d) {
var domain = d.email_address.split('@')[1];
// is this a new domain?
if (!newData.hasOwnProperty(domain)) {
newData[domain] = [];
}
// add entry
newData[domain].push(d);
});
// get and sort domains alphabetically
var domains = Object.keys(newData).sort();
//console.log(domains, newData);
// build table
var html = '<table>';
domains.forEach(function(domain) {
html += '<tr><td colspan="3">' + domain + '</td></tr>';
newData[domain].forEach(function(entry) {
html += '<tr>';
html += '<td>' + entry.email_address + '</td>';
html += '<td>' + entry.number_of_orders + '</td>';
html += '<td>' + entry.total_order_value + '</td>';
html += '</tr>';
});
});
html += '</table>';
$('#Reports').html(html);
});
table {
border: 1px solid #000;
border-collapse: collapse;
}
td {
border: 1px solid #000;
padding: 5px;
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div id="Reports"></div>
