'HTMLElement' is undefined in IE8, an alternative?
Coding

Hey all I have methods like this:


// Has Class
HTMLElement.prototype.hasClass = function (searchClass) {
return this.className.match(new RegExp('(s|^)' + searchClass + '(s|$)'));
}

In IE9 it works fine. In IE8 it gives me undefined... is there a simple work around?


Javascript object that maps keys to value & allows iteration over keys

Nth-of-type alternative for IE8
Coding

I have rows of product divs. Need to add a clear div after every fourth item. 4 to a row.


I'm using jQuery('.product:nth-of-type(4n+2)').after("<div class='clear'></div>"); right now, but that doesn't support IE8. And since we're using jQuery, selectivizrs fix won't work in this case.


I've also tried


addDynamicRow = function() {
var divs = $(".product-section > .product");
for(var i = 0; i < divs.length; i+=4) {
divs.slice(i, i+4).wrapAll("<div class='row'></div>");
}

Coding

I have some calculations that rely on window.innerHeight. But as I have found out this is not available in any IE except IE9. All the other options I have looked at don't even come close to the figure I get when I use window.innerHeight.


Does anybody have a work around?
