I have come across that old problem that using embedded views gives you ‘dodgy’ alt tags when you mouse over the twistie icon. I did do a search and didnt really come across anything useful so thought I would post this in case it helps anyone else.
Add the following function to the js header and then call it in the onload event. It automatically overwrites the default alt tag with something a little more user friendly. I hope this is useful to anyone searching for a solution to this. FYI the image resource is called openfolder.gif.
function adjustTwisties(){
var twistieA = document.getElementsByTagName("a");
for (var x = 0; x < twistieA.length; x++ ) {
if(twistieA[x].innerHTML.indexOf("openfolder.gif") > -1) {
var twistie = twistieA[x].getElementsByTagName("img");
if(twistie[0].src.indexOf("ImgIndex=1") > -1){
twistie[0].title = "Collapse this category.";
twistie[0].alt = "";
}
if(twistie[0].src.indexOf("ImgIndex=0") > -0){
twistie[0].title = "Expand this category.";
twistie[0].alt = "";
}
}
}
}
