<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <script src="jquery/jquery-1.8.0.min.js" type="text/javascript"></script> <title></title> </head> <body> <input id="input" value="default" type="text" /> </body> </html> <script> var input = document.getElementById('input'); // vbKeyReturn 13 // vbKeySeparator 108 input.onkeydown = function (e) { e = e || event; if (e.keyCode == 13) { //判斷是否單擊的enter按鍵(回車鍵) alert( $('#input').val()) } } </script>
