将数组或字符串 [] 的 C# 字符串分配给 javascript 数组 [英] assign C# string of array or string[] to javascript array
问题描述
我有一个 js 代码，其中一个数组在它像
var availableTags = ["动作脚本","AppleScript","阿普",基本的"，C"];然后我在我的代码中创建了一个数组字符串或者像类级别的 .cs
public static string[] test={"animal","lovely"};然后我把js数组改成了这个
var availableTags = "<%=test%>";//也试过不加引号现在我没有像以前的js数组那样得到结果
使用完整代码进行编辑，我从 http://jqueryui.com/中获取的 jquery演示/自动完成/#multiple
使用系统；使用 System.Collections.Generic;使用 System.Linq；使用 System.Web；使用 System.Web.UI；使用 System.Web.UI.WebControls;使用 System.Collections;使用 System.Web.Script.Serialization；公共部分类 onecol : System.Web.UI.Page{JavaScriptSerializer 序列化器；public static string test = "['animal','lovely']";公共静态字符串检查；protected void Page_Load(object sender, EventArgs e){serializer = new JavaScriptSerializer();//序列化器this.detail.ToolsFile = "BasicTools.xml";测试 = returnTitle();}}和 html 的脚本是
<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">$(函数(){var availableTags = <%=test%>;函数拆分(val){返回 val.split(/,s*/);}函数extractLast(term) {返回 split(term).pop();}$("#tags")//选择项目时不要离开选项卡上的字段.bind("keydown", 函数(事件){if (event.keyCode === $.ui.keyCode.TAB &&$(this).data("autocomplete").menu.active) {event.preventDefault();}}).自动完成({最小长度:0，来源:功能(请求，响应){//委托回自动完成，但提取最后一项响应($.ui.autocomplete.filter(availableTags,extractLast(request.term)));},焦点:函数(){//防止在焦点上插入值返回假；},选择:功能(事件，用户界面){var term = split(this.value);//移除当前输入条款.pop();//添加选中的项目条款.push(ui.item.value);//添加占位符以获取末尾的逗号和空格条款.push("");this.value = term.join(", ");返回假；}});});</asp:内容><asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="服务器"><div class="demo" ><div class="ui-widget"><label for="tags">标记编程语言:</label><input id="Text1" class="#tags" size="50"/> 实际上它是一个自动完成功能来提供标签，我想从 C# 代码中获得的自动完成标签建议，我从 jqueryui.com/demos/autocomplete/#multiple 获取了 Jquery 源代码，然后我尝试给它 C#.cs 文件中的字符串，我用编辑版本的代码解释了它，后面的 C# 代码与链接中的完全一样
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.
公共静态类 JavaScript{公共静态字符串序列化(对象 o){JavaScriptSerializer js = new JavaScriptSerializer();返回 js.Serialize(o);}}然后你可以使用那个类来序列化你需要的项目
//C#数组(asp页面成员)protected string[] Values = { "Sweet", "Awesome", "Cool" };<script type="text/javascript">var testArray = <%=JavaScript.Serialize(this.Values) %>I have a js code in which an array works well when its like
var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C"
];
I then made an array string in my code behind or .cs like on class level
public static string[] test={"animal","lovely"};
I then changed js array to this
var availableTags = "<%=test%>"; // also tried without quotes
Now I m not having the results as was having with previous js array
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();
}
}
and the script with html is
<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>
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
You need to serialize the C# string array into a javascript array.
http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx
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);
}
}
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>
