麻烦更改链接悬停背景颜色

Question

This should be a simple thing to do, but I cant seem to change the hover background-color on the tweets on the following page:

http://www.studiopsk.com/news.html

All the other links are fine, but the ones on the latest tweets won't seem to change?

Using this to try...

<script>
    if(sessionStorage.getItem("visited") != "true"){
var colors = Array("#A3F8EF", "#FF7275", "#CBB6E7", "#FF9D74", "#FDF874"), idx;
idx = Math.floor(Math.random() * colors.length); // Pick random index
sessionStorage.setItem("colour", colors[idx]);
newColour = sessionStorage.getItem("colour");
}
newColour = sessionStorage.getItem("colour");

$("div.tweets_txt a").hover(function(){
  $(this).css("background-color", newColour+"!important");
}, function() {
  $(this).css("background-color","transparent");
});  
sessionStorage.setItem("visited", "true");
</script>

It's a bit unclear what you're trying to accomplish, and I think just setting a class on the elements based on situation will make your life easier. But it appears that you're talking about the problem being for new elements added to the page, if that's the case, it appears that you are using javascript that's being executed in HTML, and not on any event, just on page load, which means it will only run once, at page load. And won't effect any elements added to the page dynamically at a later time.
