I use this javascript to resize, to a max of 800px, a big (5Mb) image on a page:
<script type="text/javascript">
$(document).ready(function () {
$('.detailImg').each(function () {
var maxWidth = 800; // Max width for the image
var maxHeight = 800; // Max height for the image
var ratio = 0; // Used for aspect ratio
var width = $(this).width(); // Current image width
var height = $(this).height(); // Current image height
// Check if the current width is larger than the max
if (width > maxWidth) {
ratio = maxWidth / width; // get ratio for scaling image
$(this).css("width", maxWidth); // Set new width
$(this).css("height", height * ratio); // Scale height based on ratio
height = height * ratio; // Reset height to match scaled image
width = width * ratio; // Reset width to match scaled image
}
// Check if current height is larger than max
if (height > maxHeight) {
ratio = maxHeight / height; // get ratio for scaling image
$(this).css("height", maxHeight); // Set new height
$(this).css("width", width * ratio); // Scale width based on ratio
width = width * ratio; // Reset width to match scaled image
}
});
});
When page is loaded the image is not resized. No errors on FireBug console. If I try to refresh the page with F5, the image get resized! If I try Ctrl + F5, images return at original size!
Where is the problem? Why this javascript only works when the page is refreshed?
