i am working on a project in which i require the width of a image from href when i click on the specific image the width if the image displays in a alert .
the following is the href and image code i am using
<li>
<a href="<?php echo $pic;?>?id=<?php echo $id;?>&pic=<?php echo $picID;?>" data-title="" data-desc=" " data-rel="group2" data-bw="<?php echo $pic;?>" class="lightbox" id="plzx" >
<img src="<?php echo $pic;?>" width="160" height="160" title="Click To View"/></a>
</li>
whenever i try to get the width of the image it takes the image width from the img tag not from the href . as the img tag width is already defined "160" . is there a way possible for getting the width of the image from the <a href
i am using the following code which is nit working
$('a').click(function() {
var image = $("<img />").attr("src", $(".lightbox").attr("href"));
$(document).append(image);
alert(image.height());
alert(image.width());
image.remove();
});
the html code
<li>
<a href="uploads/kareena-kapoor-144a_$1$Ni5.St4.$kPORmHFjcfGBJjn2KHSis0.jpg?id=3&pic=101" data-title="" data-desc=" " data-rel="group2" data-bw="uploads/kareena-kapoor-144a_$1$Ni5.St4.$kPORmHFjcfGBJjn2KHSis0.jpg" class="lightbox" id="plzx" >
<img src="uploads/kareena-kapoor-144a_$1$Ni5.St4.$kPORmHFjcfGBJjn2KHSis0.jpg" width="160" height="160" title="Click To View"/></a>
</li>
Based on something like:
ReplyDelete<a href="/path/to/big.jpg"><img src="/path/to/small.jpg"></a>
This should do it:
$('a').click(function() {
$(new Image()).load(function() {
alert(this.width); // image width
alert(this.height); // image height
}).attr('src', this.href);
});
Update: If you need to continue your program using the width/height, try:
var width,height;
$('a').click(function() {
$(new Image()).load(function() {
width = this.width;
height = this.height,
onLoaded();
}).attr('src', this.href);
});
function onLoaded() {
alert(width);
alert(height);
// continue...
}
You don’t need to append the temporary image to the document, but you do need to add a load listener before you extract width/height.
Remember that the AdBlock extension can affect the outcome of the extraction in webkit, so please turn it off when debugging.
