一个例子

1、在"d:\\web"目录下，建立一个子目录lib，在这个目录建立一个文本文件，文件名为"ajaxform.js"，文件内容为：

//异步发送对象
function sendJsonObjectAsyn(){
    var obj=new Object();
    obj.name = "hehui";
    obj.age=39;
    sendAjaxJSON(obj,"json.htm","afterSendJson"); //afterSendJson为发送完成后要执行的对象
}

//异步发送JSON字符串
function sendJsonStringAsyn(){
    var val= \'{"name":"李云龙","age":"36"}\';
    sendAjaxJSON(val,"json.htm","afterSendJson");//afterSendJson为发送完成后要执行的对象
}

//显示服务器返回的数据
function afterSendJson(result){
    document.getElementById("p1").innerHTML=result;
}

2、HttpRequest事件代码：

Select Case e.Path
    Case "test.htm"
        Dim wb As New weui
        wb.AddForm("","form1","test.htm")
        With wb.AddButtonGroup("form1","btg1",True)  \'垂直排列
            .Add("btn1", "发送jason对象","button").Attribute=""
            .Add("btn2", "发送jason字符串","button").Attribute=""
        End With
        wb.AppendHTML("<div id=\'p1\' style=\'margin:0.5em\'></div>") \'插入一个div,用于显示服务器返回的数据
        wb.AppendHTML("<script src=\'./lib/ajaxform.js\'></script>") \'引入脚本文件
        e.WriteString(wb.Build) \'生成网页
    Case "json.htm"
        Dim sb As New StringBuilder
        Dim jo As JObject = JObject.Parse(e.PlainText)
        sb.AppendLine("服务器收到的数据有:<br/>")
        sb.AppendLine("name:" & jo("name").ToString & "<br/>")
        sb.AppendLine("age:" & jo("age").ToString)
        e.WriteString(sb.ToString)
End Select
