我有一个 js 代码，其中一个数组在它喜欢的时候工作得很好

var availableTags = [
            "ActionScript",
            "AppleScript",
            "Asp",
            "BASIC",
            "C"
                     ];

然后我在我的代码中创建了一个数组字符串或者类级别的 .cs

 public static string[] test={"animal","lovely"};

然后我将 js 数组更改为此

 var availableTags =  "<%=test%>"; // also tried without quotes 

现在我没有像以前的 js 数组那样的结果

使用完整代码编辑，我从http://jqueryui.com/demos/autocomplete/#multiple 中获取的jquery

  using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Collections;
using System.Web.Script.Serialization;

public partial class onecol : System.Web.UI.Page
{
   JavaScriptSerializer serializer;

   public static string test = "['animal','lovely']";
    public static string check;


    protected void Page_Load(object sender, EventArgs e)
    {
       serializer = new JavaScriptSerializer();
        //serializer
        this.detail.ToolsFile = "BasicTools.xml";
        test = returnTitle();
    }

}

而带有html的脚本是

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<script type="text/javascript" src="Jscript.js"></script>  
     <script type="text/javascript" src="jquery-1.7.1.min.js"></script> 
     <script type="text/javascript" src="jquery-ui-1.8.17.custom.css"></script>  
     <link href="~/jquery-ui-1.8.17.custom.css" rel="stylesheet" type="text/css"/>
      <script type="text/javascript">
          $(function () {
                var availableTags =  <%=test%>;

              function split(val) {
                  return val.split(/,\s*/);
              }
              function extractLast(term) {
                  return split(term).pop();
              }

              $("#tags")
              // don't navigate away from the field on tab when selecting an item
            .bind("keydown", function (event) {
                if (event.keyCode === $.ui.keyCode.TAB &&
                        $(this).data("autocomplete").menu.active) {
                    event.preventDefault();
                }
            })
            .autocomplete({
                minLength: 0,
                source: function (request, response) {
                    // delegate back to autocomplete, but extract the last term
                    response($.ui.autocomplete.filter(
                        availableTags, extractLast(request.term)));
                },
                focus: function () {
                    // prevent value inserted on focus
                    return false;
                },
                select: function (event, ui) {
                    var terms = split(this.value);
                    // remove the current input
                    terms.pop();
                    // add the selected item
                    terms.push(ui.item.value);
                    // add placeholder to get the comma-and-space at the end
                    terms.push("");
                    this.value = terms.join(", ");
                    return false;
                }
            });
          });
    </script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

<div class="demo" >
<div class="ui-widget">
    <label for="tags">Tag programming languages: </label>
    <input id="Text1" class="#tags" size="50" />


</div>
</div>

实际上它是一个提供标签的自动完成功能，我想从 C# 代码中获取标签的自动完成建议，我从 jqueryui.com/demos/autocomplete/#multiple 获取了 Jquery 源代码，然后我试图给它 C#来自 .cs 文件的字符串，我用编辑版本的代码对其进行了解释，其背后的 C# 代码与链接中的代码完全一样

最佳答案

您需要将 C# 字符串数组序列化为 javascript 数组。

http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx

通常我会创建一个简单的静态类作为包装器。

public static class JavaScript
{
    public static string Serialize(object o)
    {            
        JavaScriptSerializer js = new JavaScriptSerializer();
        return js.Serialize(o);
    }
}

然后你可以使用那个类来序列化你需要的项目

//C# Array(Member of asp page)
protected string[] Values = { "Sweet", "Awesome", "Cool" };

<script type="text/javascript">
    var testArray = <%=JavaScript.Serialize(this.Values) %>
</script>
