JavaScript 中的位置
你好，我的代码有问题.. 为什么它不起作用..？ 我的代码有问题吗？
function selectWord() {
var select = window.getSelection();
if (select.getBoundingClientRect) {
var rect = select.getBoundingClientRect ();
x = rect.left;
y = rect.top;
w = rect.right - rect.left;
h = rect.bottom - rect.top;
alert (" Left: " + x + "\n Top: " + y + "\n Width: " + w + "\n Height: " + h);
}
else {
alert ("Your browser does not support!");
}
}

我的猜测是您在不支持它的浏览器中使用它。
IE 不支持 getSelection，Fx 3.7 应该是第一个支持 getBoundingClientRect
Firefox 的 getBoundingClientRect 问题
My guess is you are using this in a browser that does not support it.
IE does not support getSelection and Fx 3.7 should be the first one to support the getBoundingClientRect
getBoundingClientRect problem with Firefox
getBoundingClientRect 是一个 DOM Node 方法，getSelection 方法的结果不是 DOM Node。
可能有一种方法可以使用返回的 Selection 的anchorNode、anchorOffset、focusNode 和 focusOffset 属性。
如果您使用 firefox + firebug，您可以执行 console.log(select) 并检查您有权访问的属性。
getBoundingClientRect is a DOM Node method, the result of the getSelection method is not a DOM Node.
There might be a way using the anchorNode, anchorOffset, focusNode and focusOffset properties of the Selection that is returned.
If you use firefox + firebug, you can do console.log(select) and inspect the properties that you have access to.
