Question

今天早上我发布了一个关于选择jQuery脚本的问题，这是我能够从经典的asp中选择的jquery多选框中检索值，有人问我演示代码所以在构建它时，一切似乎都有效一切都很突然，并且认为你知道我已经老了，但是在尝试实现代码后我遇到了同样的问题，但我想我可能已经找到了我正在反对的问题。您将在下面找到所涉及的代码：

这包括2种形式的所选jquery（http://harvesthq.github.com/chosen/），顶部是普通表格，第二种是带上传功能的表格，我已经包含下面的代码两页：

'example.jquery.html'的代码

<!doctype html> 
<html lang="en"> 
<head>
  <link rel="stylesheet" href="chosen/chosen.css" />
</head>
<body>
<h3>Chosen without enctype="multipart/form-data"</h3>
<form action="CollectChosenData.asp?type=plain" method="post" name="ExampleChosen">
<div id="container">
    Multiple Select<br><br>
    <select data-placeholder="Your Favorite Types of Bear" style="width:350px;" multiple class="chzn-select" name="ChosenData" tabindex="8">
        <option value=""></option>
        <option value="1">American Black Bear</option>
        <option value="2">Asiatic Black Bear</option>
        <option value="3">Brown Bear</option>
        <option value="4">Giant Panda</option>
        <option value="5" selected>Sloth Bear</option>
        <option value="6">Sun Bear</option>
        <option value="7" selected>Polar Bear</option>
        <option value="8">Spectacled Bear</option>
    </select>
    <br>
    <br>

    text field:
    <input type="text" name="othertext" value="text value">
    <br>
    <br>
    <input type="submit" name="ExampleChosenSubmit" value="Post form">
  </div>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js" type="text/javascript"></script>
  <script src="chosen/chosen.jquery.js" type="text/javascript"></script>
  <script type="text/javascript"> $(".chzn-select").chosen();</script>
  </form>
<br>
<hr>
<br>

<h3>Chosen with enctype="multipart/form-data"</h3>
<form action="CollectChosenData.asp?type=upload" method="post" name="ExampleChosenUpload" enctype="multipart/form-data">
<div id="container">
    Multiple Select<br><br>
    <select data-placeholder="Your Favorite Types of Bear" style="width:350px;" multiple class="chzn-select" name="ChosenData" tabindex="8">
        <option value=""></option>
        <option value="1">American Black Bear</option>
        <option value="2">Asiatic Black Bear</option>
        <option value="3">Brown Bear</option>
        <option value="4">Giant Panda</option>
        <option value="5" selected>Sloth Bear</option>
        <option value="6">Sun Bear</option>
        <option value="7" selected>Polar Bear</option>
        <option value="8">Spectacled Bear</option>
    </select>

    <br>
    <br>

    other field:
    <input type="file" name="mytestfile" value="">
    <br>
    <br>

    text field:
    <input type="text" name="othertext" value="text value">
    <br>
    <br>
    <input type="submit" name="ExampleChosenSubmit" value="Post form">
  </div>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js" type="text/javascript"></script>
  <script src="chosen/chosen.jquery.js" type="text/javascript"></script>
  <script type="text/javascript"> $(".chzn-select").chosen();</script>
  </form>
</body>
</html>

'CollectChosenData.asp'的代码

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>
<head>
    <title>Untitled</title>
</head>

<body>
<% 
If Request.Querystring("type") = "plain" Then
    Response.write "Value collected from chosen select box: '"& Request.Form("ChosenData") &"'<br/>"
    Response.write "Value collected from text field: '"& Request.Form("othertext") &"'<br/>"
ELseIf Request.Querystring("type") = "upload" Then
    Set objUpload = Server.CreateObject("Persits.Upload")
        objUpload.OverwriteFiles = False
        objUpload.SetMaxSize 1048576    ' Limit files to 1MB
        objUpload.SaveVirtual "/upload"
        Response.write "Value collected from chosen select box: '"& objUpload.Form("ChosenData") &"'<br/>"
        For Each File in objUpload.Files
            Response.write File.FileName &"<br/>"
        Next
        Response.write "Value collected from text field: '"& objUpload.Form("othertext") &"'<br/>"
    Set objUpload = nothing
End if

 %>
<br>
<br>
Return and <a href="example.jquery.html">try again</a>
</body>
</html>

现在为什么第一个表单（普通版本）会为“ChosenData”返回正确的值而第二个表单没有？

非常感谢你的帮助和回复家伙，他一边挠头一边说......

Answer 1

您的问题似乎是上传组件只显示了一个选择的多个值。

请参阅"Upload.Form returns only the first selected item of a multi-select control"。

如解决方法所示，您必须遍历名为ChosenData的每个表单元素并显示。

选择Jquery，在vbscript / classic asp和ASPupload中检索多个选择值

'example.jquery.html'的代码

'CollectChosenData.asp'的代码
