jquery：匹配所選表格行的所有電子郵件

Question

我卡在這裏。就像提取所有的mailto: hrefs並用分隔符分隔它們。

HTML

<table class="table table-striped fadeactions users"> 

    <tbody> 
    <tr class="user" id="user_21278"> 
     <td class="dim">21278</td> 
     <td> 
     <input checked="checked" id="user_ids_" name="user_ids[]" type="checkbox" value="true" /> 
     </td> 
     <td>Helga</td> 
     <td class="fadeactions col-md-2"> 
     <a data-placement="top" data-title="User details and assigned groups" data-toggle="tooltip" href="https://stackoverflow.com/users/21278"><i class="fa fa-user"></i></a> 
     <a data-placement="top" data-title="Email to" data-toggle="tooltip" href="mailto:aaa@helga.com"><i class="fa fa-envelope-o"></i></a> 

     </td> 
    </tr> 

    <tr class="user" id="user_18333"> 
     <td class="dim">18333</td> 
     <td> 
     <input checked="checked" id="user_ids_" name="user_ids[]" type="checkbox" value="true" /> 
     </td> 
     <td>Franziska</td> 
     <td class="fadeactions col-md-2"> 
     <a data-placement="top" data-title="User details and assigned groups" data-toggle="tooltip" href="https://stackoverflow.com/users/18333"><i class="fa fa-user"></i></a> 
     <a data-placement="top" data-title="Email to" data-toggle="tooltip" href="mailto:franziska@ksgr.be"><i class="fa fa-envelope-o"></i></a> 
     </td> 
    </tr> 

    </tbody> 
</table> 

<br/> 
<textarea id="maila"></textarea> 

jQuery的

$('tr td:has(input:checkbox:checked) ~ td > a').each (i, e) -> 
    em=$(e).attr('href').match('mailto\\:.*').replace('mailto:','') 
    $('#maila').append(em); 

其實複選框匹配和郵寄地址：比賽的工作，但煥添加替換功能我沒有輸出了。 感謝您也展示如何在地址之間插入分隔符（;）。 最後，我想有：

franziska@ksgder.be; irene@triich.com

還找了JSFiddle

的例子試試這個：

var emails = []; 
 

 
$('tr td:has(input:checkbox:checked) ~ td > a[href^="mailto"]') 
 
    .each(function() { 
 
    console.log('test'); 
 
    var 
 
     $this = $(this), 
 
     email = $this.attr('href').replace('mailto:', ''); 
 

 
    emails.push(email); 
 
    }); 
 

 
$('#maila').val(emails.join(';'));
