MouseOver event to change TD background and text

I need to change the td background to grey and text in another td when the user's mouse goes over the f开发者_C百科irst mentioned td.

I have done this so far:

<td onMouseOver="this.style.background='#f1f1f1'" onMouseOut="this.style.background='white'">

but this only changes the background of the first td and does not change the text in the second td.

Any ideas please?

Have a look at this:

function highlightNext(element, color) {
    var next = element;
    do { // find next td node
        next = next.nextSibling;
    }
    while (next && !('nodeName' in next && next.nodeName === 'TD'));
    if (next) {
        next.style.color = color;
    }
}

function highlightBG(element, color) {
    element.style.backgroundColor = color;
}

HTML:

<td onMouseOver="highlightBG(this, 'red');highlightNext(this, 'red')" 
    onMouseOut="highlightBG(this, 'white');highlightNext(this, 'black')" >

Note that adding the event handler in the HTML is not considered to be good practice.

Depending on which browser you want to support (it definitely won't work in IE6), you really should consider the CSS approach which will work even if JS is turned off. Is much less code and it will be easier to add this behaviour to multiple elements:

td:hover {
    background-color: red;          
}

td:hover + td {
    color: red;   
}

DEMO

You should give that other td an id and access it from your onmouseover event handler. Maybe you should put that onmouseover code into its own function and call it from the onmouseover.
