一开始去ZeroclipBoard 官网下载最新版本（2.x），后来才发现根本就不支持IE浏览器，IE浏览器打开官网也是报错。

ZeroclipBoard 的git有一段说明：

ZeroClipboard v2.x is expected to work in IE9+ and all of the evergreen browsers.
Although support for IE7 & IE8 was officially dropped in v2.0.0,
 it was actuallystill technically supported through v2.0.2.

现在改成1.x版本，兼容IE浏览器：

/**
 * @author default.fu@foxmail.com 
 * @description 复制 为了兼容IE9- ZeroClipboard 放弃2.x使用1.x版本
 * @param $o
 * @param text
 */
function initCopy($o, text) {
    if (typeof text == 'undefined') {
        if ($o instanceof jQuery) {
            text = $o.val() || $o.html() || $o.text() || 'NULL';
        } else {
            if (typeof $o.value != 'undefined') {
                text = $o.value;
            } else if (typeof $o.innerHTML != 'undefined') {
                text = $o.innerHTML;
            } else {
                text = 'NULL';
            }
        }
    }
    var client = new ZeroClipboard($o);
    client.on('load', function (client) {
        client.on('datarequested', function (client) {
            client.setText(text);
        });

        client.on('complete', function (client, args) {
            alert('复制成功 ' + text);
        });
    });
    client.on('wrongflash noflash', function () {
        alert('flash error');
        ZeroClipboard.destroy();
    });
}
