<li> 悬停事件 <div> 内

Question

I'm using the AJAX control toolkits autocomplete in a really old project of mine. I have some problem with the mouseover highlighting.

In the example that works, the generated <li> tags gets a mouseover event which changes their background color using inline css. Works well. However, when i change the markup from:

<li>
    Hello world
</li>

to

<li>
    <div>Hello</div>
    <div>world</div>
</li>

The <li> element will only change background color when i hover a part of them which is not covered by one of the divs.

Since I can't modify the generated (and minified) javasacript, I'm looking for a quick and dirty fix.

I have tried to change the z-index of the elements, without success. I've also tried to find the event of the li and add it to the div. But I can't find a way to copy events that is not added by jquery to another element.

Any ideas here are much appreciated.

Below if the reverted minified javascript if its to any help:

_highlightItem: function(item) {   
    /// <summary>   
    /// Highlights the specified item   
    /// </summary>   
    /// <param name="item" type="Sys.UI.DomElement" DomElement="true" mayBeNull="false" />   
    /// <returns />   

    var children = this._completionListElement.childNodes;   

    // Unselect any previously highlighted item   
    for (var i = 0; i < children.length; i++) {   
        var child = children[i];   
        if (child._highlighted) {   
            if (this._completionListItemCssClass) {   
                Sys.UI.DomElement.removeCssClass(child, this._highlightedItemCssClass);   
                Sys.UI.DomElement.addCssClass(child, this._completionListItemCssClass);   
            } else {   
                if (Sys.Browser.agent === Sys.Browser.Safari) {   
                    child.style.backgroundColor = 'white';   
                    child.style.color = 'black';   
                } else {   
                    child.style.backgroundColor = this._textBackground;   
                    child.style.color = this._textColor;   
                }   
            }   
            this.raiseItemOut(new AjaxControlToolkit.AutoCompleteItemEventArgs(child, child.firstChild.nodeValue, child._value));   
        }   
    }   

    // Highlight the new item   
    if(this._highlightedItemCssClass) {   
        Sys.UI.DomElement.removeCssClass(item, this._completionListItemCssClass);   
        Sys.UI.DomElement.addCssClass(item, this._highlightedItemCssClass);   
    } else {   
        if (Sys.Browser.agent === Sys.Browser.Safari) {   
            item.style.backgroundColor = 'lemonchiffon';   
        } else {   
            item.style.backgroundColor = 'highlight';   
            item.style.color = 'highlighttext';   
        }   

    }   
    item._highlighted = true;   
    this.raiseItemOver(new AjaxControlToolkit.AutoCompleteItemEventArgs(item, item.firstChild.nodeValue, item._value));   
},

Why not use CSS to add the needed highlights?

li > div:hover {
  /* Highlight Rule Here */
}
