javascript - 悬停时更改 CSS

Question

我尽量把它们分开。

<div id="a" onmouseover="chbg('red')" onmouseout="chbg('white')">This will change b element</div>
<div id="b">This is element b</div>

<div id="f" onmouseover="chbg('blue')" onmouseout="chbg('white')">This will change g element</div>
<div id="g">This is element g</div>

<div id="j" onmouseover="chbg('yellow')" onmouseout="chbg('white')">This will change k element</div>
<div id="k">This is element k</div>

这是JS

function chbg(color) {
    document.getElementById('b').style.backgroundColor = color;
    document.getElementById('g').style.backgroundColor = color;    
    document.getElementById('k').style.backgroundColor = color;    
}

这里不能正常工作 http://jsfiddle.net/qUzn5/ .

Answer 1

您可能想像这样在函数中添加第二个参数:

JavaScript:
function chbg(color, id) { document.getElementById(id).style.backgroundColor = color;<br/> }

HTML:
(重复 div)

<div id="a" onmouseover="chbg('red', 'a')" onmouseout="chbg('white')">This will change b element</div>
