推荐答案

CreateTextRange是 Microsoft特定功能，但有一个简单的解决方法。

CreateTextRange is a Microsoft specific function, but there is an easy work around.

使用 createRange ，而不是这篇文章例如：

if (document.selection) { //IE
    var range = document.body.createTextRange();
    range.moveToElementText(document.getElementById(containerid));
    range.select();
} else if (window.getSelection) { //others
    var range = document.createRange();
    range.selectNode(document.getElementById(containerid));
    window.getSelection().addRange(range);
}
