為了省事很多時(shí)候希望可以按回車鍵來(lái)提交表單，要控制這些行為，可以借助JS來(lái)達(dá)到要求。
代碼如下：

解決方案：
把form表單放在一個(gè)div里面 ，然后對(duì)這個(gè)div監(jiān)聽(tīng)事件$("#id").keydown(function (){});
#*#監(jiān)聽(tīng)回車事件
document.onkeydown=function() {
if(event.keyCode==13) {
//這里提交你的表單
$('#ff_login').submit();
}
}
#*#頁(yè)面編寫js腳本進(jìn)行監(jiān)聽(tīng)。。。
#*#js監(jiān)聽(tīng)enter事件#*#
把form表單放在一個(gè)div里面 ，然后對(duì)這個(gè)div監(jiān)聽(tīng)事件$("#id").keydown(function (){});
#*#獲取焦點(diǎn) 監(jiān)聽(tīng)enter#*#
監(jiān)聽(tīng)整個(gè)body的keypress事件，如果是回車鍵，激發(fā)submit按鈕的click事件，當(dāng)然你的click事件中會(huì)有相關(guān)的數(shù)據(jù)驗(yàn)證之類的，如果驗(yàn)證不過(guò)，不會(huì)提交。
希望本文所述對(duì)大家jsp程序設(shè)計(jì)有所幫助。
