一个非常酷的复制到剪贴板技术

function copy(meintext) {
    if (window.clipboardData) {
        window.clipboardData.setData("Text", meintext);
    } else {
        var flashcopier = "flashcopier";
        if (!document.getElementById(flashcopier)) {
            var divholder = document.createElement("div");
            divholder.id = flashcopier;
            document.body.appendChild(divholder);
        }
        document.getElementById(flashcopier).innerHTML = "";
        var divinfo = "<embed src=\"http://img.alimama.cn/images/_clipboard.swf\" FlashVars=\"clipboard=" + encodeURIComponent(meintext) + "\" width=\"0\" height=\"0\" type=\"application/x-shockwave-flash\"></embed>";
        document.getElementById(flashcopier).innerHTML = divinfo;
    }
    alert("copy ok!");
