推荐答案

这在showModalDialog文档报价上的 MSDN

Quote from showModalDialog documentation on MSDN

无论是模式还是无模式HTML对话框支持文本选择或复制操作的标准快捷菜单;但是，您可以通过使用脚本的TextRange对象和事件处理程序onmousedown事件和的OnMouseMove，如下面的例子模仿此功能。

Neither modal nor modeless HTML dialog boxes support text selection or the standard shortcut menu for copy operations; however, you can imitate this functionality by using script with TextRange objects and event handlers for onmousedown and onmousemove, as in the following example.

作为一种替代方法，你可以实现自己的模态对话框

As an alternative you can implement your own modal dialog

var dlg = window.open(url, '_blank', 'modal=yes,dialog=yes');

var winFocus = window.onfocus;

window.onfocus = function() {
    if (dlg /* && possible additional condition based on dialog flow */) {
        dlg.focus();
    } else {
        window.onfocus = winFocus;
        // callback for dialog closing
    }
}
