Issue in Opera with the $(window).load(function(){}); script

In order to display the body's main div height correctly after all content (images) have loaded, I utilized a combination of jQuery and CSS.

//The CSS used is as follows
body {display: none;}


/* Function to calculate div block height */
function recalculateHeight(id, add){
 var height = $(id).height();

 if (height < 650) height = 650;

 if (add)
  height = height + add;

 $('#left_div').height(height);
 $('#center_div').height(height);
 $('#right_div').height(height);
}
//Recalculate height when the page is fully loaded
$(document).ready(function(){
 $(window).load(function(){
  $('body').show();
  recalculateHeight("#center_div");
 });
});

While this method works well in IE, Firefox, and Safari, there are some issues in Chrome and Opera. In Chrome, the height calculation works but the body does not hide, causing the images to load normally. In Opera, neither functions work as intended, resulting in either the page not showing after content loads or incorrect page calculation.

Understanding the distinction between $(document).ready() and a regular load event (like $(window).load())) is crucial.

The "document ready" event triggers when the entire document is prepared for JavaScript interaction - all HTML and JavaScript are loaded. However, not all images may be loaded, and the loading and application of CSS may vary across browsers.

Performing layout or size calculations from $(document).ready() may not be ideal. It could lead to trying to determine the document's size before all images are loaded, resulting in incorrect dimensions before the browser fully understands the content's size.

In my experience, switching to the load event instead of document.ready has proven successful in Opera.

Another factor to consider is that Opera delays loading images within content set to display:none until the display property is altered to make the images visible. While this boosts loading speed, it may cause users to wait for image loading when additional content is revealed.

Answer №2

Consider this alternative approach:

//adjust height after page fully loads
 $(window).load(function(){
  $('body').show();
  adjustHeight("#center_div");
 });

instead of using:

$(document).ready(function(){
 $(window).load(function(){
  $('body').show();
  adjustHeight("#center_div");
 });
});

Answer №3

An improved approach involves setting the dimensions of your images directly in the html code. This eliminates the need for using window.load since the height won't be altered.

Additionally, Sarfraz's point highlights the importance of not nesting window.load inside document.ready. Both should be placed at the same level.
