我正在使用以下函数来获取所选文本,它在所有主流浏览器中都运行良好但在版本9之前的IE中无法正常工作!

function getSelected() {
    var t = '';
 if (window.getSelection) {
     t = window.getSelection();
} else if (document.getSelection) {
    t = document.getSelection();
    t = t.toString();
} else if (document.selection) {
    t = document.selection.createRange();
    t = t.text;
}
    return t;
}

var txt = getSelected();

这里的问题是,在版本9之前的IE中,它不会在变量“txt”中存储任何文本

以下内容取自How to get selected html text with javascript?

这个javascript函数适用于IE7及以上版本:

function getSelected() {
    var text = "";
    if (window.getSelection
    && window.getSelection().toString()
    && $(window.getSelection()).attr('type') != "Caret") {
        text = window.getSelection();
        return text;
    }
    else if (document.getSelection
    && document.getSelection().toString()
    && $(document.getSelection()).attr('type') != "Caret") {
        text = document.getSelection();
        return text;
    }
    else {
        var selection = document.selection && document.selection.createRange();

        if (!(typeof selection === "undefined")
        && selection.text
        && selection.text.toString()) {
            text = selection.text;
            return text;
        }
    }

    return false;
}

在chrome,IE10,IE6,IE7中测试
