Expand and collapse child row on click of a link in the parent row of a table

enter image description here

Guys i'm a newbie to jQuery. I've to make the child rows in a table to hide and show on click of a link in the parent row. I've tried to use jQuery toggle, but i dont know how to make it work when there are multiple rows.

Here's the table -

<table class="table table-striped reportTable">
<thead>
<tr>
<th>Product Type</th>
<th>Product Name</th>
<th>Face Value</th>
<th>My Stock</th>
<th>Ordered Stock</th>
<th>Sub Account Stock</th>
</tr>
</thead>
<tbody>
<tr>
<td><a class="showhr" href="#">SIM</a></td>
<td></td>
<td></td>
<td>574,888</td>
<td>0</td>
<td>0</td>
</tr>
<tr class="aser"> <!--child row-->
<td></td>
<td>EPin £5</td>
<td>£05</td>
<td></td>
<td></td>
<td></td>
</tr>
<tr class="aser"> <!--child row-->
<td></td>
<td>EPin £10</td>
<td>£15</td>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<td><a class="showhr" href="#">SIM</a></td>
<td></td>
<td></td>
<td>574,888</td>
<td>0</td>
<td>0</td>
</tr>
<tr class="aser"> <!--child row-->
<td></td>
<td>EPin £5</td>
<td>£05</td>
<td></td>
<td></td>
<td></td>
</tr>
<tr class="aser"> <!--child row-->
<td></td>
<td>EPin £10</td>
<td>£15</td>
<td></td>
<td></td>
<td></td>
</tr>
</tbody>
</table>


jQuery -

<script type="text/javascript">
$(document).ready(function () {
$(".showhr").click(function () {
$(".aser").toggle("slow", function () {
});
});
})
</script>


I'm not sure if jQuery toggle is a good idea for this. Any help would be appreciated. Thanks.

Answer

You can do it using closest() and nextUntil() methods and :has() pseudo selector like following.

$(".showhr").click(function() {
    $(this).closest('tr').nextUntil("tr:has(.showhr)").toggle("slow", function() {});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="table table-striped reportTable">
    <thead>
        <tr>
            <th>Product Type</th>
            <th>Product Name</th>
            <th>Face Value</th>
            <th>My Stock</th>
            <th>Ordered Stock</th>
            <th>Sub Account Stock</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td><a class="showhr" href="#">SIM</a></td>
            <td></td>
            <td></td>
            <td>574,888</td>
            <td>0</td>
            <td>0</td>
        </tr>
        <tr class="aser">
            <!--child row-->
            <td></td>
            <td>EPin £5</td>
            <td>£05</td>

            <td></td>
            <td>EPin £10</td>
            <td>£15</td>
            <td></td>
            <td></td>
