jquery implements enter login

1. button button submission method

//按钮事件
$(‘#btnSumit‘).click(function() {
  alert(‘测试‘);
});
 //回车提交事件
$("body").keydown(function() {
  if (event.keyCode == "13") {//keyCode=13是回车键
    $(‘#btnSumit‘).click();
  }
});

2. form submission method

　 a. Use jquery

$("body").bind(‘keyup‘,function(event) {
  if(event.keyCode==13){
    document.form.submit();
  }  
});

b. Non-jquery 

<body onkeyup="autosubmit()">//添加监听事件
function autosubmit(){//事件触发函数
 if(event.keyCode==13){
   document.form.submit();
 }  
}
