如何在经典 ASP 中返回 JSON 对象

2022-01-16 00:00:00 json asp-classic ajax

我想使用经典的 ASP 脚本返回一个 JSON 对象(它是 AJAX 请求的一部分).

I want to return a JSON object using a classic ASP script (it's part of an AJAX request).

如果我只是将回复发送为如下文本:

If I just send the reponse as text like:

response.write("{ query:'Li', suggestions:['Liberia','Libyan Arab Jamahiriya','Liechtenstein','Lithuania'], data:['LR','LY','LI','LT'] }")

这会起作用吗，还是我真的需要一个 JSON 库?

will this work, or do I actually need a JSON library?

我正在尝试在 http://www.devbridge.com/projects/autocomplete/jquery/#howto 工作.

I'm trying to get the autocomplete plugin at http://www.devbridge.com/projects/autocomplete/jquery/#howto to work.

javascript:

javascript:

 $(document).ready(function() {
    var a = $('#txtValue').autocomplete({ 
    serviceUrl:'script.asp',
    minChars:2, 
    maxHeight:400,
    width:300,
    zIndex: 9999,
    deferRequestBy: 0, //miliseconds
    onSelect: function(value, data){ alert('You selected: ' + value + ', ' + data); },
});

平均售价:

<% 
response.ContentType = "application/json"
response.write("{ query:'Li', suggestions:['Liberia','Libyan Arab Jamahiriya','Liechtenstein','Lithuania'], data:['LR','LY','LI','LT'] }") 
%>

自动完成功能不起作用.如果我使用像这样的本地查找数组，它会起作用查找:['一月'，'二月'，'三月'，'四月'，'五月']

Autocomplete is not working. It works if I use a local lookup array like lookup: ['January', 'February', 'March', 'April', 'May']

但是 ajax 有问题，这意味着它不能正确返回列表.

But there's something wrong with the ajax meaning it doesn't return the list properly.

推荐答案

好像是客户端解析错误.

It appears to be a parsing error on the client side.

我不认为这会有所作为，但看起来如果你引用所有内容，包括属性名称，它似乎可以工作.并使用双引号而不是单引号 - 这显然会有所作为.

I didn't think this would make a difference, but it looks like if you quote everything, including the property names, it seems to work. And use double-quotes instead of single quotes - that apparently is making a difference.

记得把你的双引号加倍(至少我认为你在 VBScript 中是这样做的——已经很久了).

Remember to double your double-quotes (at least I think that's how you do it in VBScript - been a long time).

所以:

<%
    Response.ContentType = "application/json"
    Response.Write("{ ""query"":""Li"", ""suggestions"":[""Liberia"",""Libyan Arab Jamahiriya"",""Liechtenstein"",""Lithuania""], ""data"":[""LR"",""LY"",""LI"",""LT""] }")
%>
