使用jQuery从外部网站获取价值

所以我有一个外部页面：

http://api.aghost.net/api/futures/index.cfm?Username=E020521102&Password=ksc0rNX&service=table&style=3&layout=chart&showGrid=0&symbols=@C@3&colorLabels=0&contractFormat=2&dateFormat=short&fontsize=large&timeFormat=m&dateFormat=m

我试图从中检索"345'4"，但我的代码只给了我一个对象，当我在对象上运行".toSource"时，我收到以下输出：

({0:{}, length:1, prevObject:{0:{location:({}), icpsignup:{0:{}, 1:{}, 2:{}, 3:{}, 4:{}, 5:{}, 6:{}, 7:{}, 8:{}, 9:{}}, jQuery1710019525210189072606:2}, context:{location:({}), icpsignup:{0:{}, 1:{}, 2:{}, 3:{}, 4:{}, 5:{}, 6:{}, 7:{}, 8:{}, 9:{}}, jQuery1710019525210189072606:2}, length:1}, context:{location:({}), icpsignup:{0:{}, 1:{}, 2:{}, 3:{}, 4:{}, 5:{}, 6:{}, 7:{}, 8:{}, 9:{}}, jQuery1710019525210189072606:2}, selector:"div.month.left span.big"})

我做错了什么？我觉得我已经接近解决方案了，但我缺少了一些东西。。

以下是我的代码：

var data = 'http://api.aghost.net/api/futures/index.cfm?Username=E020521102&Password=ksc0rNX&service=table&style=3&layout=chart&showGrid=0&symbols=@C@3&colorLabels=0&contractFormat=2&dateFormat=short&fontsize=large&timeFormat=m&dateFormat=m';
var $row1 = jQuery("div.month.left span.big"),  $row2 = jQuery("#cpuloaddynamic"), $row3 = jQuery("#meminfodynamic");
$.get("index.html", function(data){
    var $data=$(data);
    $row1.html( $data.find('tbody > tr:first-of-type > td:nth-of-type(5)').html() );
});
alert($row1.toSource());

我从以下文章开始：jquery：从外部html加载值并填充许多本地<div>字段，只需读取一次html

这是我编辑过的代码：

var data = 'http://api.aghost.net/api/futures/index.cfm?Username=E020521102&Password=ksc0rNX&service=table&style=3&layout=chart&showGrid=0&symbols=@C@3&colorLabels=0&contractFormat=2&dateFormat=short&fontsize=large&timeFormat=m&dateFormat=m';
var $row1 = jQuery("div.month.left span.big"),  $row2 = jQuery("#cpuloaddynamic"), $row3 = jQuery("#meminfodynamic");
$.get(data, function(data){
    var $data=$(data);
    $row1.html( $data.find('tbody > tr:first-of-type > td:nth-of-type(5)').html() );
    alert( $data.find('tbody > tr:first-of-type > td:nth-of-type(5)').html() );
});
