loading saving and showing json results in javascript

I have a php file called rows2.php that shows results like so after entering new fields in a database. It is simply showing the new id of the field :-
{'new_id':'92'}
I want to load this with javascript and add the new_id to existing list with : either side of the number and display it but I seem to be struggling? Many thanks.
The javascript to load the page and get the result is :
$.getJSON("rows2.php", function(result) {
var new_id=console.log(result[0].new_id);
document.getElementById('vehicle_list').value = '' + document.getElementById('vehicle_list').value + 'new_id' + ':';
})

You should use
document.getElementById('vehicle_list').innerHTML = ''+document.getElementById('vehicle_list').innerHTML+'new_id'+':';
instead of
document.getElementById('vehicle_list').value = ''+document.getElementById('vehicle_list').value+'new_id'+':';
.value is used only in case of input elements otherwise you must use .innerHTML

Don't put the variable name (new_id) in quotes.
document.getElementById('vehicle_list').value = '' + document.getElementById('vehicle_list').value + new_id + ':';

Display thumbnailPhoto from Active Directory using Javascript only - Base64 encoding issue

Here's what I'm trying to do:
From an html page using only Javascript I'm trying to query the Active Directory and retrieve some user's attributes.
Which I succeded to do (thanks to some helpful code found around that I just cleaned up a bit).
I can for example display on my html page the "displayName" of the user I provided the "samAccountName" in my code, which is great.
But I also wanted to display the "thumbnailPhoto" and here I'm getting some issues...
I know that the AD provide the "thumbnailPhoto" as a byte array and that I should be able to display it in a tag as follow:
<img src="data:image/jpeg;base64," />
including base64 encoded byte array at the end of the src attribute.
But I cannot manage to encode it at all.
I tried to use the following library for base64 encoding:
https://github.com/beatgammit/base64-js
But was unsuccesful, it's acting like nothing is returned for that AD attribute, but the photo is really there I can see it over Outlook or Lync.
Also when I directly put that returned value in the console I can see some weird charaters so I guess there's something but not sure how it should be handled.
Tried a typeof to find out what the variable type is but it's returning "undefined".
I'm adding here the code I use:
var ADConnection = new ActiveXObject( "ADODB.connection" );
var ADCommand = new ActiveXObject( "ADODB.Command" );
ADConnection.Open( "Data Source=Active Directory Provider;Provider=ADsDSOObject" );
ADCommand.ActiveConnection = ADConnection;
var ou = "DC=XX,DC=XXXX,DC=XXX";
var where = "objectCategory = 'user' AND objectClass='user' AND samaccountname='XXXXXXXX'";
var orderby = "samaccountname ASC";
var fields = "displayName,thumbnailPhoto";
var queryType = fields.match( /,(memberof|member),/ig ) ? "LDAP" : "GC";
var path = queryType + "://" + ou;
ADCommand.CommandText = "select '" + fields + "' from '" + path + "' WHERE " + where + " ORDER BY " + orderby;
var recordSet = ADCommand.Execute;
fields = fields.split( "," );
var data = [];
while(!recordSet.EOF)
{
var rowResult = { "length" : fields.length };
var i = fields.length;
while(i--)
{
var fieldName = fields[i];
if(fieldName == "directReports" && recordSet.Fields(fieldName).value != null)
{
rowResult[fieldName] = true;
}
else
{
rowResult[fieldName] = recordSet.Fields(fieldName).value;
}
}
data.push(rowResult);
recordSet.MoveNext;
}
recordSet.Close();
console.log(rowResult["displayName"]);
console.log(rowResult["thumbnailPhoto"]);
(I replaced db information by Xs)
(There's only one entry returned that's why I'm using the rowResult in the console instead of data)
And here's what the console returns:
LOG: Lastname, Firstname
LOG: 񏳿က䙊䙉Āā怀怀
(same here Lastname & Firstname returned are the correct value expected)
This is all running on IE9 and unfortunetly have to make this compatible with IE9 :/
Summary:
I need to find a solution in Javascript only
I know it should be returning a byte array and I need to base64 encode it, but all my attempts failed and I'm a bit clueless on the reason why
I'm not sure if the picture is getting returned at all here, the thing in the console seems pretty small... or if I'm nothing doing the encoding correctly
If someone could help me out with this it would be awesome, I'm struggling with this for so long now :/
Thanks!

jQuery Ajax + Classic ASP return error 'unexpected end of input'

I have two problems on this combination.
After Ajax always return error (unexpected end of input),In localhost it still can save date successfully, seems not a big problem.
The code works in my localhost but does not work in 1App Server(http://www.1apps.net/), I had tried to submit a technique question and them had a response quickly with this way http://www.mikesdotnetting.com/article/98/ajax-with-classic-asp-using-jquery
However, I think the way in that article should be working but I am confused why my code is only work in localhost and other web server but not 1App. The following is my code:
ASP:
if request.QueryString("action")="CostUpdate" then
Response.ContentType = "application/json"
a = request.form("GI")
b = request.form("GP")
c = request.form("NA")
Set rs = Server.CreateObject("ADODB.Recordset")
sql = "Select * From Cost where CostDate = #" & date() & "# and CostItem ='" & a & "'"
rs.open sql,conn,1,3
if rs.eof then
Set rs = Server.CreateObject("ADODB.Recordset")
sql = "Select * From Cost"
rs.open sql,conn,1,3
rs.addnew
rs("CostDate")=date()
rs("CostItem")=a
rs("CostAmount")=c
rs("CostNumber")= b * c
rs.update
else
Set rs = Server.CreateObject("ADODB.Recordset")
sql = "Select * From images where CostDate =#" & adid & "# and CostItem = " & a
rs.open sql,conn,1,3
rs("CostAmount")=c
rs("CostNumber")=b * c
rs.update
end if
end if
JS
var $GoodsId = $("#costtable tbody").find("tr").eq(c).find("input").eq(1).val();
var $GoodsPrice = $("#costtable tbody").find("tr").eq(c).find("input").eq(2).val();
var $NewAmount = $("#costtable tbody").find("tr").eq(c).find("input").eq(3).val();
$.ajax({
url: 'work.asp?action=CostUpdate',
type: "POST",
data: {
GI: $GoodsId,GP: $GoodsPrice,NA: $NewAmount
},
dataType: "json",
error: function (xhr, status, error) {
console.info("CallAjax");
console.info('An error occured.. ' + xhr.responseText + '..' + error);
},
success: function () {
console.info("Sucess");
}
});

there are several problems in asp code:
Don't open new sql command when rs is still open. So I created a
new recordset (rs2) to use inside the if block.
You don't need to recreate rs for every action. so i deleted repeating
createobject.
There is no need to set contentType to Json because no data is generated. You are only updating database.
Use rs.open sql,objcon,2,2 when you want to use sql update command.
use rs.close and also set rs=nothing to free server memory.
there is no definition for parameter adid. do you defined it somewhere else?
You are posting data to asp page not getting. So you have to use
request.form in first line and also send parameter "action" within posted data.
is this entire asp codes? where do you define conn?
Besides the error "unexpected end of input" is not an ASP error. You may forgot } inside JavaScript codes. the presented code is OK, check entire your code.
if request.form("action")="CostUpdate" then
a = request.form("GI")
b = request.form("GP")
c = request.form("NA")
Set rs = Server.CreateObject("ADODB.Recordset")
Set rs2 = Server.CreateObject("ADODB.Recordset")
sql = "Select * From Cost where CostDate = #" & date() & "# and CostItem ='" & a & "'"
rs.open sql,conn,1,3
if rs.eof then
sql = "Select * From Cost"
rs2.open sql,conn,2,2
rs2.addnew
rs2("CostDate")=date()
rs2("CostItem")=a
rs2("CostAmount")=c
rs2("CostNumber")= b * c
rs2.update
rs2.close
else
sql = "Select * From images where CostDate =#" & adid & "# and CostItem = " & a
rs2.open sql,conn,2,2
rs2("CostAmount")=c
rs2("CostNumber")=b * c
rs2.update
rs2.close
end if
rs.close
end if
set rs=nothing
set rs2=nothing

Javascript (and JSP) won't create table properly with if statement

So i'm using multiple if statements to draw data from a database based on the users search criteria.
What i'm struggling with is
if(request.getParameter("searchProperty")!= ""){
SearchStatement = "town_city = '" + request.getParameter("searchProperty") + "'";
if(request.getParameter("bedrooms") != "0"){
SearchStatement += " AND bedrooms = '" + request.getParameter("bedrooms") + "'";
}
}
with the idea that this concatenates a string to use as a query in the database, and bring back the results the user is searching for (this is a property searching website). I thought i'd done the if statement correctly. From what i understand, from what i've put, if the user were to select 0 in bedrooms it should return ALL results, but instead it returns NONE (who wants a house without a bedroom..) Can somebody explain what's going wrong please?
here's where the SQL statement is built and input
MyProperties = bookSQL.executeQuery("SELECT * FROM PROPERTIES WHERE " + SearchStatement);
with the expected outcome being, for example
SELECT * FROM PROPERTIES WHERE Location = 'input' AND Bedrooms = 'value'
unless value = 0 where it should just be
SELECT * FROM PROPERTIES WHERE Location = 'input'

i think the problem is with this statement,
request.getParameter("bedrooms") != "0"
should be something like this ,
(!request.getParameter("bedrooms").isEmpty())
Remember you are comparing the strings
so if is "0"
if(request.getParameter("bedrooms").equals("0")){
return SearchStatement ;
}
else {
SearchStatement += " AND bedrooms = '" + request.getParameter("bedrooms") + "'"
}
Hope this helps!!

On Click event not firing from code behind

In my code below , my ("OnClick") is not firing. Does anyone know why?
e.Row.Cells(1).Attributes("OnClick") = "window.location.href='MachineSweepLite.aspx?AreaID='" _
+ GridView1.DataKeys(e.Row.RowIndex).Values("ID").ToString()
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Cells(1).Attributes("onmouseover") = "this.style.cursor='hand';this.style.textDecoration='underline';"
e.Row.Cells(1).Attributes("onmouseout") = "this.style.textDecoration='none';"
Dim Index As Integer = e.Row.RowIndex
e.Row.Cells(1).Attributes("OnClick") = "window.location.href='MachineSweepLite.aspx?AreaID='" + GridView1.DataKeys(e.Row.RowIndex).Values("ID").ToString
End If
End Sub
Edit above.

You have a error in your attribute, as you are adding the value of the ID after the closing single quote...
For example, if the ID was 12, you're sending this to the browser...
window.location.href='MachineSweepLite.aspx?AreaID='12
Note that the 12 is not part of the URL.
You should have the following instead...
e.Row.Cells(1).Attributes("onclick") =
string.Format("window.location.href='MachineSweepLite.aspx?AreaID={0}';",
GridView1.DataKeys(e.Row.RowIndex).Values("ID").ToString())
Also note, as of .NET 4.0 it is unnecessary to have the _ character when spanning over multiple lines.

e.Row.Attributes("onClick") = "CallFunction('" & Convert.ToString(GridView1.DataKeys(e.Row.RowIndex).Values("ID")) & "');"
JS code:
function CallFunction(val)
{
// do your login here
