指定数组或字符串[] C＃的字符串数组的JavaScript [英] assign C# string of array or string[] to javascript array

问题描述

我有一个js code的数组，其中效果很好时，其像

I have a js code in which an array works well when its like

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

然后我在我的code做了数组字符串后面或的.cs像一流水平

I then made an array string in my code behind or .cs like on class level

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

我再变JS数组这个

I then changed js array to this

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

现在我不是有作为与previous JS数组具有结果

Now I m not having the results as was having with previous js array

完整code，我从 HTTP采取的jQuery编辑：// jQueryUI的.COM /演示/自动/＃多

Editing with complete code,the jquery I taken from http://jqueryui.com/demos/autocomplete/#multiple

  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();
    }

}

和使用HTML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>

其实它是一种自动完成功能，给标签，用于标记自动完成建议，我想从C＃code搞定，我把jQuery的源从jqueryui.com/demos/autocomplete/#multiple然后我试着把它从cs文件C＃字符串，我用code解释它编辑的版本，使用C＃code背后的工作原理完全作为其在链接

actually its a auto complete functionality to give tags ,the auto complete suggestions for tagging I want to get from C# code ,I took Jquery source from jqueryui.com/demos/autocomplete/#multiple and then I tried to give it C# string from .cs file , I explained it with code on edited version , with C# code behind it works exactly as its in the link

推荐答案

您需要将C＃字符串数组序列化为JavaScript数组。

You need to serialize the C# string array into a javascript array.

<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx\">http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx

通常我创建了一个简单的静态类的包装。

Usually I create a simple static class as a wrapper.

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

然后你可以使用这个类序列化，你需要的项目

Then you can use that class to serialize the item you need to

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

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