var textTitle = "this is a test"
var result = textTitle.replace(' ', '%20');

但是替换函数在""的第一个实例处停止,我得到了

结果: "this%20is a test"

关于我哪里出错的任何想法我确定它是一个简单的修复.

是否可以订购第一个查询并保留返回的行作为第一个,而不是命令第二个查询.(如果那样的话)

我目前的调查的一个例子是:

SELECT
    *
FROM 
    Devices
WHERE
    Live = 'true'
    AND Category = 'apple'
ORDER BY
    ListOrder
UNION
SELECT
        *
    FROM
        Devices
    WHERE
        DeviceLive = 'true'

我希望apple类别下的设备可以按照列表顺序进行组织,并且位于其他设备上方列表的顶部.但这似乎将两个问题混杂在一起.

我是ASP.NET和C#的新手我花了一天时间学习ASP.NET成员资格提供程序的基础知识我已经构建了所有的验证程序,但是在页面上输出我的错误消息时遇到了困难.

private void LogCreateUserError(MembershipCreateStatus status, string username)
{
    string reasonText = status.ToString();

    switch (status)
    {
        case MembershipCreateStatus.DuplicateEmail:
        case MembershipCreateStatus.DuplicateProviderUserKey:
        case MembershipCreateStatus.DuplicateUserName:

            reasonText = "The user details you entered are already registered.";
            break;

        case MembershipCreateStatus.InvalidAnswer:
        case MembershipCreateStatus.InvalidEmail:
        case MembershipCreateStatus.InvalidProviderUserKey:
        case MembershipCreateStatus.InvalidQuestion:
        case MembershipCreateStatus.InvalidUserName:
        case MembershipCreateStatus.InvalidPassword:

            reasonText = string.Format("The {0} provided was invalid.", status.ToString().Substring(7));
            break;
        default:
            reasonText = "Due to an unknown problem, we were not able to register you at this time";
            break;

    }

   //CODE TO WRITE reasonText TO THE HTML …

我目前在ASP.NET中设置了一个基本的会员系统,并使用了

<asp:PasswordRecovery ID="PasswordRecovery1" Runat="server"></asp:PasswordRecovery>

要处理密码恢复,哪个工作得很好,但如何自定义电子邮件,如更改"主题"和电子邮件的实际正文内容？
