Answer 1

使用它，将Anchor的值存储到一个新变量中：

var linkval = document.getElementById('goal').innerHTML;

它会将Value存储到变量＆＃34; linkval＆＃34;。

Answer 2

自

<a id="Goal" style="color:#FF0000" href="http://www.somewhere.com" target="_blank"> 
is first child of  <td class="text-left" >

因此，您可以在javascipt中进行，如下所示

$('td:first-child a').text();

and then convert it to a number for further usage
