.Net 在搜索时不触发 Javascript (?) - 应该忽略默认值

Question

问题：当我使用 btnSearch_Click(sender As Object, e As EventArgs) Handles btnSearch.Click, btnSearchTop.Click 时，代码完美运行并忽略默认情况下帮助用户的任何 'shown' 值，即在 'street' 框中显示 'street'.

但是当我运行 btnRiskRating_Click(sender As Object, e As CommandEventArgs) 它在这些值中所以我最终得到一个具有值的搜索（如果我然后点击 'btnSearch_Click' 它可以正常工作）。我认为这与 e As 部分有关，但这根本不是我的强项！如果您需要 javascript，我也可以弹出。

有两个 'search' 按钮，一个是 'quick link'，在这个内部网站案例中，80-90% 的时间基本上都是他们需要的。

Protected Sub btnRiskRating_Click(sender As Object, e As CommandEventArgs)

        Dim vRiskRating As String = Trim(e.CommandArgument.ToString())

        Session.Item("sRiskRating") = vRiskRating.ToString

        With oAuditData
            .EventType = "LOG"
            .EventDescription = "User clicked Risk Rating  " & vRiskRating.ToString & ""
            .PemcoModule = "All"
            .SiteID = 0
            .UserID = CInt(oUser.UserID)
            .EmployeeID = Session("EmployeeID")
        End With
        oAudit.WriteAuditTrailItem(oAuditData)


        Call PrcSearch()

    End Sub

    Protected Sub btnSearch_Click(sender As Object, e As EventArgs) Handles btnSearch.Click, btnSearchTop.Click

        Call PrcSearch()

    End Sub

    Public Sub PrcSearch()

        Session.Item("sUPRN") = Trim(sUPRN.Text)
        Session.Item("sStreet") = Trim(sStreet.Text)
        Session.Item("sSurveyCompany") = Trim(sSurveyCompany.Text)
        Session.Item("sPostcode") = Trim(sPostcode.Text)
        Session.Item("sPropertyName") = Trim(sPropertyName.Text)
        Session.Item("sDateFrom") = sDateFrom.Text
        Session.Item("sDateTo") = sDateTo.Text

        Dim vSearch As String

        vSearch = Trim(sUPRN.Text) & " - " & Trim(sSurveyCompany.Text) & " - " & Trim(sPostcode.Text)
        vSearch = vSearch & " - " & Trim(sPropertyName.Text) & " - "
        '& Trim(sDateFrom.Text) & " - " & Trim(sDateTo.Text)

        With oAuditData
            .EventType = "LOG"
            .EventDescription = "User searched " & vSearch & ""
            .PemcoModule = "All"
            .SiteID = 0
            .UserID = CInt(oUser.UserID)
            .EmployeeID = Session("EmployeeID")
        End With
        oAudit.WriteAuditTrailItem(oAuditData)

        Call PrcActionsCSVReport()

        With oAuditData
            .EventType = "LOG"
            .EventDescription = "User search CSV created " & vSearch & ""
            .PemcoModule = "All"
            .SiteID = 0
            .UserID = CInt(oUser.UserID)
            .EmployeeID = Session("EmployeeID")
        End With
        oAudit.WriteAuditTrailItem(oAuditData)

我发现我们有一个 javascript 代码只适用于 btnSearch 触发器，但现在已经修改了。

.Net 在搜索时不触发 Javascript (?) - 应该忽略默认值

.Net not triggering Javascript on search (?) - should ignore default value

javascript

vb.net
