Question

这是一个奇怪的问题，我甚至无法找到一个好的方式来回答谷歌。

我有一个使用主页/内容页面的asp.net Web表单站点。在一个页面上，javascript函数位于顶部，名为＆＃34; rePrintPrompt＆＃34;。当我运行该站点时，使用localhost来测试javascript函数名称就会出现在asp面板的上方。

我无法在显示功能名称的代码中的任何位置找到它。

这是aspx代码：

        if (answer == null || answer == "")
        {
            answer = prompt("Is this a reprint job? Y/N", "N")
        } else if(answer == "Y")
        {
            var answer2 = prompt("Please enter Order #, Mark #, and Qty:")
            if (answer2 == nul || answer2 == "")
            {
                answer2 = prompt("Please enter Order #, Mark #, and Qty:")
            } else
            {
                var answers = str.split(",")
                document.getElementById('<%= hOrderNumber.ClientID %>').value = answers[0]
                document.getElementById('<%= hMarkNumber.ClientID %>').value = answers[1]
                document.getElementById('<%= hQty.ClientID %>').value = answers[2]
                document.getElementById('<%= hRePrint.ClientID %>').value = "Y"
                document.getElementById('<%= btnPieceLabels.ClientID %>').click()
            }

为什么要显示名称？我以前从未见过这种情况。

非常感谢任何帮助。

编辑：在后面的代码中，这是引用该函数的唯一位置：

    Private Sub Reports_Load(sender As Object, e As EventArgs) Handles Me.Load
    'Get passed order number
    oNumber = Request.QueryString("ordernum").ToString()
    btnPieceLabels.Attributes.Add("onclick", "rePrintPrompt")
    If Not ClientScript.IsStartupScriptRegistered("rePrintPrompt") AndAlso Not IsPostBack Then
        ClientScript.RegisterClientScriptBlock(Me.[GetType](), "rPrintLabels", "rePrintPrompt")
    End If

使用浏览器开发人员工具检查页面后，我发现了这个：

我不知道为什么会将此添加到页面中。

Answer 1

好的，所以经过几个月弄乱这个问题后，我终于找到了问题的来源。

在页面加载的代码隐藏文件中，我有一个客户端注册脚本行：

ClientScript.RegisterClientScriptBlock(Me.[GetType](), "cqar", "closeqar")

在双引号中具有closeqar的最后一个段是流氓文本的来源。我只是将其更改为＆＃34;＆＃34;文字消失了。所以这一行现在写着：

ClientScript.RegisterClientScriptBlock(Me.[GetType](), "cqar", "")

Answer 2

我认为问题在于你根本不需要RegisterClientScriptBlock。您的脚本已在页面上。 RegisterClientScriptBlock用于向页面添加新脚本。您所需要的只是Attributes.Add部分。

btnPieceLabels.Attributes.Add("onclick", "rePrintPrompt")
// If Not ClientScript.IsStartupScriptRegistered("rePrintPrompt") AndAlso Not IsPostBack Then
//    ClientScript.RegisterClientScriptBlock(Me.[GetType](), "rPrintLabels", "rePrintPrompt")
// End If

（我不确定vb.net中的评论是否为双斜线或滴答。）

编辑：我刚注意到您的按钮上已经有OnClientClick，因此您也不需要btnPieceLabels.Attributes.Add。

JS函数名称出现在asp.net内容页面上
