Passing Cookies With Jquery Ajax Request From A Different Domain?

Jun 9, 2010

I'm building a greasemonkey script to make posting to craigslist a lot easier for our clients.

Basically the flow is this:

User logs into our system (established authentication cookies with asp.net)User navigates to a section on our site called "CraigsList". If they have the greasemonkey script installed it automatically opens up craigslist in a new tab.

The greasemonkey script then does a request back to our site at [URL] to retrieve a list of available items to be posted to craigslist.

This is where it fails because the request to [URL] is not including any of the authentication cookies. I'm not sure if it doesn't include the cookies because the request originates from [URL] and not [URL] or what. I know it's an authentication issue because looking at it in fiddler it returns a 302 and redirects to the login page.

Here is my request:

Jquery - Why Same Domain Ajax Request Adding Jsonp Callback Parameter

Feb 25, 2011

I have a simple script making a request to the server:

var DTO = { 'path': path };
var url = 'default.aspx/Get';
var test;
$('#getInstance').click(function () {
$.ajax({
url: url,
type: 'POST',
dataType: 'json',
data: JSON.stringify(DTO),
contentType: 'application/json; charset=utf-8',
success: function (msg) {
test = msg;
},
error: function (jqXHR, textStatus, errorThrown) {
alert(textStatus);
alert(errorThrown);
}
});
});

This works fine as in it connects to the server and gets the data back, with one simple problem. It is treating this request as a cross domain request, therefore using jsonp. The server code is here:

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static MyObject Get(string path)
{
MyObject foo = new MyObject();
return foo;
}

Normally this would not be a problem, except that I am accessing a WebMethod, and it doesnt have the capability to return a jsonp response (meaning it has no way to attach the callback function to the response. Now, if this was a manual response, I could hack it up and attach the parameter, but I am taking advantage of the built-in serialization, so no way to mess around with the response. [URL]

Let me just stress the fact that this code works. The only problem is jQuery treating this request as cross domain. But Why? UPDATE: Well, after many more hours and more testing I have narrowed this issue down to it being a bug in jquery 1.5.1. I did some testing with older versions (all 1.4 versions) and I had no problem, the request was made using JSON, and the response was received successfully. What could be the change they made that would consider this request a CORS?

AJAX :: Check Whether A Particular Record Exists In Database Using JQuery

Aug 18, 2015

I have a asp:Button and asp:Textbox on Default.aspx page

Code is as below:

<asp:Button ID="Button1" runat="server" Text="Save" Width="80px" CommandName="Update"
OnClientClick="EnableDdlCompany();saveButtonClick();" CommandArgument="Save" OnClick="btnSave_Click"/>
<asp:TextBox ID="txtBarcodeNumber" runat="server" MaxLength="11" Width="230px"
Text='<%# Bind("BarcodeNo") %>' Display="None"
OnTextChanged="TextChanged" AutoPostBack="true"></asp:TextBox>

On button click, I want to call a javascript code to check that If the entered BarCode Number in Textbox already exist in Database, then show an alert "Number already exist" else allow user to save and navigate to Default2.aspx

I can able to do the same checking on TextBox OnTextChanged event using c# code, as below:

protected void TextChanged(object sender, EventArgs e) {
TextBox txtbarcode = fvIPRForm.FindControl("txtbarcodenumber") as TextBox;
if (txtbarcode.Text.Length > 0 && txtbarcode.Text.Length < 11) {
string error = "The Barcode Number " + txtbarcode.Text + " is invalid, the barcode length must be 11 character.";
ScriptManager.RegisterStartupScript(this, typeof(string), "Successful", "alert('" + error + "');", true);

[Code] ....

Here, IPRRequest is the class/.dll file name and IsValidBarcodeTest is a function defined in the class file

But same checking I tried using the c# code on button's OnClick="btnSave_Click" event, but dont know why this event is not firing, I guess due to CommandArgument on button, but I am not sure.

That's why I want to achieve it using Javascript.

JQuery :: Ajax, JavaScript To Check Server And Disable Button Control?

Feb 1, 2011

I am developing a web application for online bidding wher I want the BID button to disable itself, on all clients, whenever someone places a bid. What I need is some javascript to ping the site to check if a bid has been placed on the server, if so, then disable the button. I was suggested to use jQuery for this, use .ajax to query the server for the check. Then use a setTimeout javascript function to keep checking.I am not javascript expert at all so any tips would be greatly appreciated. At lease where to start. Also, will I need to record every single bid in database to achieve above?
