方法如下.以下内容适用于所有主流浏览器，包括IE 6.
Here's how. The following works in all major browsers, including IE 6.
function getSelectedText() {
var selectedText = "", sel;
if (window.getSelection) {
selectedText = "" + window.getSelection();
} else if ( (sel = document.selection) && sel.type == "Text") {
selectedText = sel.createRange().text;
}
return selectedText;
}
$('#target').text( getSelectedText() );
