叮當貓咪

這就是我想出來的。經過IE，Chrome，Firefox，Safari，Opera測試。不返回空字符串。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;}
