jQuery add table row

by

Problem

How do you add a table row using jQuery?  A table has so many different elements in it that things might get screwy.

 

Solution

There is no one statement-to-use-on-all, but the below line is a pretty general answer and should solve your needs even when there are no table rows:

$('#myTable > tbody:last').append('<tr>...</tr><tr>...</tr>');

prettyPhoto undefined description

by

Problem

I had “undefined” showing up in the description of my lightbox whenever I left out the “title” attribute in my link.

 

Solution

I am using jQuery 1.6.2, the examples used 1.4.2.   To resolve the problem, look to change something like this:

 

if(pp_descriptions[set_position] != ""){
				$pp_pic_holder.find('.pp_description').show().html(unescape(pp_descriptions[set_position]));
			}else{
				$pp_pic_holder.find('.pp_description').hide();
			}

to this:

if(typeof pp_descriptions[set_position] != 'undefined' && pp_descriptions[set_position] != ""){
				$pp_pic_holder.find('.pp_description').show().html(unescape(pp_descriptions[set_position]));
			}else{
				$pp_pic_holder.find('.pp_description').hide();
			}

IE Takes Time

by

IE has officially forced me to spend 50% more time to complete a project.  Bugs, workarounds, special IE filters, all contributed to the time.  The last 3 or 4 projects, I tracked my hours spent on IE.  Maybe Microsoft secretly hates other developers.

I have a new example demonstrating a few HTML 5 features like:

  • gradient
  • vertical text
  • shadow

Of course, IE is not yet a “modern” browser so it needs to use it’s little “filter” hack.  Leave it to IE to have a bug in it’s own hack.  Gradients and Shadows cannot be shown at the same time.  I haven’t really found a workaround yet.
