Hi, I am trying to find a way to remember/store a JScript textrange and then apply it back to a text and convert it into a selection. An example: in an iframe which is in "designmode" and contains the text "This is text inside the frame", the user hilights/selects "is text".

There's a little demo script that creates widgets with the library and assemble them in a GUI. You can find it @ http://bitterspring.net/webshifter/ The problem is, it seems to work correctly on Chrome and on Firefox ...
I'm looking for a free image hosting site that lets you upload/organize images by album (preferably with a massive album size), and then allows you to embed those albums into your own website/blog. Imgur allows you to create albums but it seems to be used to hotlink to single images or link to the album on their site. Also picasa allows...

Using Javascript I'm crudely simulating Brownian motion of particles, but for some reason I don't understand my particles are drifting up and to the left. The algorithm is pretty straight forward. Each particle is a div and I simply add or subtract a random number from each div's top and left position each round. I read up on Math.rand...

When parts of the tree are hovered, their corresponding iframe elements are 'selected'. But it isn't working, for the life of me. Here is some quick half-pseudo code: function traverseTree(c,o){ //c = the tree subset ...
