Douglas Crockford proposes that loading JSON documents be moved directly into the browser, in much the same way that XMLHttpRequest is. There are many advantages to this (which Crockford outlines) including increased security and the fact that JSON has become the way to load data into the browser for AJAX applications.

We've done similar work here using the SCRIPT tag to do cross site JSON loading. Crockford's proposal would obsolete this (and we'd be happy about it).

You can read the proposal here. Hopefully some bright Firefox and IE gurus will pick up the torch for this one.

We slipped a photo album extension into the product on Friday; you can see one right here. Unfortunately, it doesn't always work on Internet Explorer -- the image sometimes displays as blank.

The explaination is here:

The issue is that changing the 'src' attribute of an <image> tag, is making the image disappear, rather than change. Frustratingly, the problem only happens in IE; Gecko behaves as expected.

I have found two work arounds: one is to pop up an alert just after chainging 'src': the icon image correctly updates when the alert dialog is popped up (before dismissing it). The second is to use a callback with the 'setTimeout' method. The first is unacceptable, the second is, IMHO, simply ugly.

We went with the setTimeout method, obviously:

onclick : function(index, again) {
    if (document.all && !again) {
        window.setTimeout("i$(ID).onclick(" + index + ", 1)", 1)
    }

Frequently test against Internet Explorer.

A few notable differences between Firefox and Internet Explorer (v7 beta) for this website:

• There's supposed to be a diagram in this post (works on IE, not FF)
• The sidebar is supposed to have little dividing lines, not huge white bars (works on FF, not IE)

We're planning to go "really" live soon, so no rest for the weary.
