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 = -1Create array with lines of plain text from a textarea.
Mozilla’s Jetpack: Firefox Extensions in Javascript!
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.
