I am trying to impliment facebook registration pluging from last three weeks, to check the username avaiablity I am using jquery and JSON, accourding to this http://developers.facebook.com/docs/plugins/registration/advanced/ guide, with the following code I am able to send username to my server that is a a c# page to check either it is available or not, but how to tell back? Problem is this I don’t know how to send message from c# page to the calling scritp, and how to use read it here.
<body>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js#appId=134552926621797&xfbml=1"></script>
<fb:registration redirect-uri="http://dev2.urecommendme.com/test3.aspx"
fields='[{"name":"name"},
{"name":"username","description":"Username","type":"text"}]'
onvalidate="validate_async"></fb:registration>
<script src="http://code.jquery.com/jquery-1.4.4.min.js"></script>
<script>
function validate_async(form, cb) {
$.getJSON('http://dev2.urecommendme.com/test01.aspx?username=' + form.username + '&callback=?',
function (response) {
if (response.error) {
// Username isn't taken, let the form submit
cb();
}
alert(cb.toString());
});
}
</script>
</body>
返回消息应该是这样的。
Returning message should be something like this
<script src="http://graph.facebook.com/shahidgfdgd?callback=jsonp1307613510850">
jsonp1307613510850({
"error": {
"type": "OAuthException",
"message": "(#803) Some of the aliases you requested do not exist: shahid"
}
});
</script>
这是我的第三个星期implimenting它请指导我，让我可以完成这个任务，谢谢。
This is my third week to implimenting it please guide me so I can complete this task, thanks.
推荐答案
FB注册页面看起来应该如下：
FB registration page should look like as follows
<body>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js#appId=134552926621785&xfbml=1"></script>
<fb:registration redirect-uri="http://dev2.urecommendme.com/test3.aspx"
fields='[{"name":"name"},
{"name":"username","description":"Username","type":"text"}]'
onvalidate="validate_async"></fb:registration>
<script src="http://code.jquery.com/jquery-1.4.4.min.js"></script>
<script>
function validate_async(form, cb) {
$.getJSON('test02.aspx?username=' + form.username,
function (response) {
if (response.error) {
// Username isn't taken, let the form submit
cb();
}
cb({ username: 'That username is taken' });
});
}
</script>
</body>
请注意我提到如何服务器文件名（无完整的URL，因为这两个文件都在同一个根目录）在validate_async（形式，CB）功能
Note how I mentioned server file name (it is without full URL, as both files were on same root dir) in validate_async(form, cb) function
$.getJSON('test02.aspx?username=' + form.username,
Test02.aspx页应该看起来像如下：
Test02.aspx page should look like as follows
请注意在test02.aspx没有HTML，躯干或头部标记
（Test02.aspx.cs）应该像
Note no html, body or head tags in test02.aspx (Test02.aspx.cs) should look like
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Newtonsoft.Json;
using System.Text;
public partial class test02 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e1)
{
StringBuilder JSON = new StringBuilder();
//validate from your database and execute one of the following two lines.
JSON.Append("{\"error\":\"Exist\"}"); // username is taken
// JSON.Append("{\"anything\":\"Not Exist\"}");
Response.Write(JSON.ToString());
Response.End();
}
}
