Clear <select> Element with jQuery

This one was tricky. Clearing a select with a unique id using $(‘#mySelectId’).val(”), $(‘#mySelectId’).selected(”), or $(‘#mySelectId’).reset() will fail/break. Even setting the selectedIndex to -1 won’t work… Unless you specify the first object in the array of objects with that unique id (even if there is only one). Example:

$('#mySelectId')[0].selectedIndex = -1

It’s more than just Javascript/HTML/CSS enabled extensions. Check out the demos. Looks very powerful. I wish Safari had an answer for this…

Quick twitter JSON call

Requires jQuery, and a some HTML.

 
function getTwitter(sn) {
	var url = "http://twitter.com/status/user_timeline/"+sn+".json?count=1&callback=?";
	$.getJSON(url, function(data){
		$.each(data, function(i, item) {
			var image = item.user["profile_image_url"];
			var text = item["text"];
		//changes the image size to 73x73px	
			image = image.replace(/normal/, "bigger");
		});        
	}); 
   //puts the image src in an existing img id=+sn+img
	$("img#"+sn+"img").attr("src", image);
   //puts the latest tweet in an existing span id=+sn+tweet
	$("span#"+sn+"tweet").text(text);
}  
//do it  
getTwitter("tbeseda");

This is mostly to test syntax highlighting on tumblr, but I thought I’d share some code anyway.
