I am working with a table that currently has 2 rows.
The first row contains an image, while the second row is hidden from view.
Using JQuery, my goal is to make this hidden row visible.
Below is the structure of the table:
<table>
<tr>
<td><img src="/default.png" alt="" /></td>
</tr>
<tr style="display:none">
<td><img src="/default2.png" alt="" /></td>
</tr>
</table>
$("td").click(function(){
$("tr:hidden").fadeIn();
});
Isn't that surprising?
To begin with, it's important to assign an Id or Class to the rows for easier reference.
<table>
<tr>
<td><img src="/default.png" alt="" class="trigger"/></td>
</tr>
<tr style="display:none" id="target">
<td><img src="/default2.png" alt="" /></td>
</tr>
</table>
Next, utilize jQuery to attach an event listener function to the trigger:
<script>
$(".trigger").click( function(){ $("#target").show(); } );
</script>
In this code snippet, trigger is indicated as a class using a dot in jQuery (i.e., .trigger), while target is identified as an Id and requires a hash symbol (e.g., #target).
You can have multiple elements sharing the same class, but typically only one element per Id.
In this example scenario, multiple images can trigger the event, while there is a single target div.
For a consistent 2nd position, consider the following code:
$('table tr:nth-child(2)').show();
If you are unsure of the exact index and have only one element:
$("tr").each(function(ele){
$(this).show();
});
Countless variations abound!
$("tr").not(':hidden').find('img').click( function(){
$(this).parent().siblings().show();
});
Create an event handler for when the image is clicked, allowing the hidden row to be shown.
For instance:
<style type="text/css">
.hide {
display: none;
}
</style>
<script type="text/javascript">
$('td img').click(function() {
$('tr:hidden').show();
});
</script>
<table>
<tr>
<td><img src="https://www.google.com/intl/en_com/images/srpr/logo3w.png" alt="Google" /></td>
</tr>
<tr class="hide">
<td>You clicked on the image!</td>
</tr>
</table>
