Remove Image And Its Container If Image Is Broken
Solution 1:
You can accomplish this in one of two ways:
Either use the removeChild function (assuming you want to remove the elements and not hide them):
function imgError(image) {
// Get image row
var imageRow = image.parentNode.parentNode;
// Get image label row
var imageLabel = imageRow.nextElementSibling;
// Get table element of that image row and remove imageLabel
imageRow.parentNode.removeChild(imageLabel);
// Get table element of that image row and remove img element
imageRow.parentNode.removeChild(imageRow);
}
Or you can instead hide your elements using the .style.visibility property of the image and label elements:
function imgError(image) {
// Get image row
var imageRow = image.parentNode.parentNode;
// Get image label row
var imageLabel = imageRow.nextElementSibling;
// Hide imageLabel
imageRow.style.visibility = 'hidden';
// Hide imageRow
imageLabel.style.visibility = 'hidden';
}
Solution 2:
well, there are multiple approaches to do this :
here, I'm assuming that you want to use Pure javescript -no jquery- and keeping the original DOM document hierarchy.
<table class='mobileTable'>
<tr> <td><img src='path/to/broken/image.jpg' onerror='imgError(this)' /></td></tr>
<tr> <td class='mobMidTitle'>some title</td></tr>
</table>
<script>
function imgError(image) {
// this will step up to get the parent of the image's parent
var imgParent = image.parentElement.parentElement;
// this will get the next sibling of the image grandpa
var nextSib = imgParent.nextElementSibling;
// reset it's html to empty
nextSib.innerHTML = '';
image.onerror = "";
image.src = "http://localhost/domain/images/error.jpg";
return true;
}
</script>
another easier approach is by adding new ID to your title TD and then remove it using javascript as follows :
/* here we've added id='mobMidTitle' */
<td class='mobMidTitle' id='mobMidTitle' >some title</td>
<script>
function imgError(image) {
image.onerror = "";
image.src = "http://localhost/domain/images/error.jpg";
document.getElementById('mobMidTitle').style.display = 'none';
// ^^^^^^^^^^^
return true;
}
</script>
Solution 3:
How about this JQuery javascipt (https://jquery.com) to hide any image that failed to load:
$("img").error(function() { $(this).hide(); });
or, if you want to hide its container you can do this:
$("img").error(function() { $(this).parent().hide(); });
or if you really want to remove the image, or container, use remove() instead of hide().
You could also display your own error image:
$("img").error(function() { $(this).attr("src","error.png"); });
Code has been tested and it works.
You can make it more specific by selecting only those images you want to hide or remove. Change $("img") to $(".hideOnError") and the use the class hideOnError on those images you want to hide or remove. Different actions could be take like replaceOnError. You can also apply this to other loadable elements.
In your specific case you have two elements you want to remove when an image fails. The best way to go about this is to associate the title with the image through attributes:
<table class='mobileTable'>
<tr><td><img id='image1' src='<?php echo $img ?>'></td></tr>
<tr><td id='image1title' class='mobMidTitle'><?php echo $title ?></td></tr>
</table>
As you can see, the id of the image here is image1 and the table cell containing the title has id image1title. To remove image and title on error, while leaving the table structure intact, you do:
$("img").error(function() {
var id = $(this).attr('id'); // get id of image
$(this).remove(); // remove image
$("#"+id+"title").empty(); // remove title
});
Solution 4:
You can replace image if img tag has broken image. Please check below code
<img src='brokenimage.jpg' onError="ImageError(this);">
<script language="JavaScript">
function ImageError(img)
{
img.src = "https://www.google.co.in/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png";
}
</script>
