Question

我试图在我的网页上完成某些事情时生成一些验证警告框，并且出于某种原因，我将所有数据库调用放入一个单独的包含文件后我的Javascript停止工作（javascript在我执行此操作之前正在工作）香港专业教育学院尝试了我能想到的一切，到目前为止没有任何工作，所以我来到最后的边界寻求帮助，这是我的html表单启动数据库调用：

<form name="requestHol" action="newbooking.asp" method="post">              

    <div id="datepicker">
        <label for="from">From </label>
        <input type="text" id="from" name="from" readonly="readonly" >
        <label for="to">to </label>
        <input type="text" id="to" name="to" readonly="readonly" >
    </div>

    <div id="reason">
        <textarea id="reasonInput" name="RequestComments" placeholder="Please enter the reason for your absence." maxlength="45" ></textarea>
    </div>

    <div id="reqbutton">
        <button name="submitHolBtn" value="requestButton" type="submit">Submit Request</button>
    </div>

</form>

这是我的ASP数据库调用：

If(Request.Form("submitHolBtn"))<>""Then

        If(Request.Form("from"))="" or (Request.Form("to"))="" or (Request.Form("RequestComments"))="" Then
            response.Write("<SCRIPT LANGUAGE=""JavaScript"">alert(""Please make sure you fill in ALL inputs when booking a holiday.""); location.href = 'newbooking.asp'</SCRIPT>")
        else

        Set objDBConn = Server.CreateObject("ADODB.Connection")
        objDBConn.Open Application("ConnString")

        Set objDBCommand = Server.CreateObject("ADODB.Command")

        objDBCommand.ActiveConnection = objDBConn
        objDBCommand.CommandText = "spNewHoliday"
        objDBCommand.CommandType = adCmdStoredProc

        objDBCommand.Parameters.Append objDBCommand.CreateParameter("@StartDate", adDate, adParamInput,200)
        objDBCommand.Parameters.Append objDBCommand.CreateParameter("@EndDate", adDate, adParamInput,200)
        objDBCommand.Parameters.Append objDBCommand.CreateParameter("@EmployeeID", adVarChar, adParamInput,200)          
        objDBCommand.Parameters.Append objDBCommand.CreateParameter("@Reason", adVarChar, adParamInput,200)
        objDBCommand.Parameters.Append objDBCommand.CreateParameter("@JobRoleID", adVarChar, adParamInput,200)  

        objDBCommand("@StartDate") = Request.Form("from")
        objDBCommand("@EndDate") = Request.Form("to")
        objDBCommand("@EmployeeID") = Session("UserID")
        objDBCommand("@Reason") = Request.Form("RequestComments")
        objDBCommand("@JobRoleID") = Session("JobRoleID")

        Set objDBRS = Server.CreateObject("ADODB.RecordSet")

        objDBRS.open objDBCommand,,adOpenForwardOnly

        Session("IsBookingValid") = objDBRS(0)

        SELECT CASE Session("IsBookingValid")
        Case "HolidayBooked"
            response.Write("<SCRIPT LANGUAGE=""JavaScript"">alert(""Holiday has been requested.""); location.href = 'newbooking.asp'</SCRIPT>")
        Case "TooManyPeopleOfFSameJob"
            response.Write("<SCRIPT LANGUAGE=""JavaScript"">alert(""Holiday CANNOT be booked, Max amount of employees with the same job role are off.""); location.href = 'newbooking.asp'</SCRIPT>")
        Case "TooManyPeopleOff"
            response.Write("<SCRIPT LANGUAGE=""JavaScript"">alert(""Holiday CANNOT be booked, Max amount of employees are already off.""); location.href = 'newbooking.asp'</SCRIPT>")
        Case "YouHaveAlreadyBookedThisDateOff"
            response.Write("<SCRIPT LANGUAGE=""JavaScript"">alert(""You have already booked these dates off.""); location.href = 'newbooking.asp'</SCRIPT>")
        Case "YouCanOnlyBookAMaxOf10Days"
            response.Write("<SCRIPT LANGUAGE=""JavaScript"">alert(""You can only book a max of 10 days off at a time.""); location.href = 'newbooking.asp'</SCRIPT>")
        Case "YouDontHaveEnoughHolidaysLeft"
            response.Write("<SCRIPT LANGUAGE=""JavaScript"">alert(""You do not have enough days left to book that holiday off.""); location.href = 'newbooking.asp'</SCRIPT>")
        Case "YouHaveAlreadyBookedAHolidayInThatPeriod"
            response.Write("<SCRIPT LANGUAGE=""JavaScript"">alert(""You already have a holiday booked off during that time period.""); location.href = 'newbooking.asp'</SCRIPT>")
        END SELECT

        Set objDBCommand=nothing
        objDBConn.Close
        Set objDBConn=nothing

        end if 
    end if

您想要使用Javascript验证表单客户端，还是使用经典asp验证服务器端。如果您想在客户端执行此操作，那么您的asp代码就无关紧要了，您需要在表单中添加一些javascript。

如果您想验证服务器端，那么您最好的选择是将您的插入代码和表单放在同一页面上，并将asp放在表单之前 - 例如

<%
If(Request.Form("submitHolBtn"))<>""Then

    If(Request.Form("from"))="" or (Request.Form("to"))="" or (Request.Form("RequestComments"))="" Then
        response.Write "<p class=""alerttext"">Please make sure you fill in ALL inputs when booking a holiday.</p>"
    else

    'your db code and cases

    end if
end if
%>

<form name="requestHol" method = "post">
<div id="datepicker">
    <label for="from">From </label>
    <input type="text" id="from" name="from" value="<%=Request.Form("from")%>" readonly="readonly" >
    <label for="to">to </label>
    <input type="text" id="to" name="to" value="<%=Request.Form("to")%>" readonly="readonly" >
</div>

<div id="reason">
    <textarea id="reasonInput" name="RequestComments" placeholder="Please enter the reason for your absence." maxlength="45" ><%=Request.Form("RequestComments")%>"</textarea>
</div>

<div id="reqbutton">
    <button name="submitHolBtn" value="requestButton" type="submit">Submit Request</button>
</div>
<form>

我根本不会使用js作为警报，只是文字。由于代码是在服务器端处理的，它只会在相关的页面上显示，并且您可以一次显示多条错误消息而不是一串js警报

你的问题在这里

 If(Request.Form("from"))="" or (Request.Form("to"))="" or (Request.Form("RequestComments"))="" Then
        response.Write("<SCRIPT LANGUAGE=""JavaScript"">alert(""Please make sure you fill in ALL inputs when booking a holiday.""); location.href = 'newbooking.asp'</SCRIPT>")
    else

如果你的任何request.form空页面将被重新加载得太快以至于你甚至都看不到任何东西 - 它又是旧页面。使用response.end为每个Request.Form执行response.write，以查看您向页面提交的内容。另外看看Session（＆＃34; IsBookingValid＆＃34;）有什么价值，如果有的话...... 在你的地方，我会在案件结束之前提出：

case else
       response.Write("<SCRIPT LANGUAGE='JavaScript'>alert('You have nothing for ASP  to work with.');</SCRIPT>")
    END SELECT

location.href =＆＃39; newbooking.asp＆＃39;当你重定向到其他地方时，这是一个很好的事情，但是因为你发布到同一个页面你不需要它，更多的它会让你感到困惑。只需确保你的response.write在正文中编写javascript而不是在标题中。

当您将asp代码移动到包含文件时，您是否偶然删除了日历的JS文件？如果是这样，那么你的所有日期选择器字段TO和FROM都将为空......

Javascript无法正常工作，经典的asp，HTML
