JS和JQuery实现Button绑定键盘Enter事件实现提交

JavaScript实现方法

document.onkeydown = function(e) {
    if (!e)
        e = window.event;//火狐中是 window.event
    if ((e.keyCode || e.which) == 13) {
        document.getElementById("loginButtonId").click(); //loginButtonId为button登录按钮的ID
    }
}

jQuery实现方法

$(window).keydown(function(e){
    var curKey = e.which;
    if(curKey == 13){
        $('#loginFormId').submit(); //loginFormId为form表单的ID
    }
})
