js实现按Ctrl+Enter发送效果

function sbFrm() {var Contenthf=document.getElementById("Contenthf");var txtAr = Contenthf.getElementsByTagName("textarea")[0];if (txtAr.innerHTML == "") {txtAr.focus();return false;}Contenthf.submit();window.opener.afterReload();return false;}

function keySend(event) {if (event.ctrlKey && event.keyCode == 13) {sbFrm();}}

function afterReload() {setTimeout(function () {window.location.reload();}, 1000);}
