<script language="javascript"> var agt=navigator.userAgent.toLowerCase(); var ie = ((agt.indexOf("msie") != -1) && (agt.indexOf("opera") == -1) && (agt.indexOf("omniweb") == -1)); function a(){ var myArea = document.getElementById("s"); var selection; if (!ie){ if (myArea.selectionStart!= undefined) { selection = myArea.value.substr(myArea.selectionStart, myArea.selectionEnd - myArea.selectionStart); } }else{ if (window.getSelection){ selection = window.getSelection(); }else if (document.getSelection){ selection = document.getSelection(); }else if (document.selection){ selection = document.selection.createRange().text; } } alert(selection) } </script> <input type="text" value="testtest" id="s" name="s" onmouseup="javascript:a()" />
[Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]
