Is “finally” the answer to all IE6 memory leak issues?
Hedger Wang has been scanning a lot of Chinese blogs lately for solutions to IE6 and memory leak issues. One of the things he stumbled upon is a pretty nifty way of nulling the objects to stop memory leaks by using the try ... finally construct. So instead of this solution which leaks memory:
-
-
function createButton() {
-
var obj = document.createElement("button");
-
obj.innerHTML = "click me";
-
obj.onclick = function() {
-
//handle onclick
-
}
-
obj.onmouseover = function() {
-
//handle onmouseover
-
}
-
return obj;//return a object which has memory leak problem in IE6
-
}
-
var dButton = document.getElementsById("d1").appendChild(createButton());
-
//skipped....
-
You can use the following which doesn't:
-
-
function createButton() {
-
var obj = document.createElement("button");
-
obj.innerHTML = "click me";
-
obj.onclick = function() {
-
//handle onclick
-
}
-
obj.onmouseover = function() {
-
//handle onmouseover
-
}
-
//this helps to fix the memory leak issue
-
try {
-
return obj;
-
-
} finally {
-
obj = null;
-
}
-
}
-
var dButton = document.getElementsById("d1").appendChild(createButton());
-
}
-
More demos, proof of concept examples and the "finally" explanation is available on Hedger's blog: Finally, the alternative fix for IE6's memory leak is available

W3C CSS Grid Positioning
Dimitri Glazkov has made a prediction that we will see CSS Grid Positioning in IE 8. This would make a lot of sense due to the fact that:
- Alex Mogilevsky, and Markus Mielke, of Microsoft wrote the spec
- If Microsoft comes out with a browser that goes above and beyond, they will be able to get rid of the monkey on their back
- CSS grids are painful right now!
This module allows you to create a layout like this:
with:
-
-
body { columns:3; column-gap:0.5in; }
-
img { float:page top right; width:3gr; }
-
It can be seen as a grid with 6 vertical lines and 2 horizontal lines.
We can use the grid lines to position the floating image
The statement "float:page top right" here positions the image at the top right corner of the page (as defined in [CSS3GCPM])
"width:3gr" makes image 3 "grid units" wide, where a "grid unit" is the distance between two adjacent grid lines. Each boundary between a column and a gap automatically produces a grid line, therefore to specify "two columns, including the gap between columns, but not including any gaps outside the columns" we can just say "3gr".
You will see more detailed examples, with lots of gr's (grid units).
