我很抱歉提出这个问题,但我只是在今天早上寻找一些指导。我只是想创建一个函数,这样我就可以通过传入该元素来使 Raphael 元素发光。下面是我的代码。为什么这不起作用?

var paper = Raphael("playarea", 500, 500);

var rectangle = paper.rect(100, 100, 200, 200, 4);

function elemHover(var el)
{

    el.hover(
    // When the mouse comes over the object //
    // Stock the created "glow" object in myCircle.g
   function() {
    this.g = this.glow({
        color: "#0000EE",
         width: 10,
         opacity: 0.8
     });
    },
    // When the mouse goes away //
    // this.g was already created. Destroy it!
    function() {
     this.g.remove();
    });
}

elemHover(rectangle);

您应该fill使用元素(在我们的例子中为矩形)来触发悬停。

rectangle.attr("fill", "red");

完整的代码看起来像

<div id="playarea"></div>

​&lt;script type="text/javascript">
var paper = Raphael("playarea", 500, 500);

var rectangle = paper.rect(100, 100, 200, 200, 4);

function elemHover(el)
{
    el.hover(
    // When the mouse comes over the object //
    // Stock the created "glow" object in myCircle.g
    function() {
     this.g = this.glow({
         color: "#0000EE",
         width: 10,
         opacity: 0.8
     });
    },
    // When the mouse goes away //
    // this.g was already created. Destroy it!
    function() {
     this.g.remove();
    });
}

rectangle.attr("fill", "red");

elemHover(rectangle);

</script>​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

更新

仅当元素被填充时才会触发悬停事件。如果你想有一个透明的元素,你可以试试

rectangle.attr("fill", "transparent");
