Passing Folder Path String To Web Service Function Via JQuery.ajax?
Apr 24, 2010
I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file):
[code]...
Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:ProjectsSamplesmytestwebsite'".
I put a break point inside MyWebMethod. When I invoke this call on the page, the break point never gets hit. It works fine when I remove all parameters from MyWebMethod's signature and pass in '{}' from JS as parameters. Once I try to pass in a string parameter, it stops working.
I have a htmlarea (Jquery plugin) where I need to accept longer strings than 2048 which seams to be the limit. I don't have a clue where to look. It's an MVC app and here are the relevant code:
HTML:
<div id="PageTextDialog" title="Ändra texten på sidan" style="display: none"> <% Using Html.BeginForm %> <%: Html.TextAreaFor(Function(model) model.PageText, 30, 30, New With {.style = "width:800px;"})%> <% End Using%> <button id="SavePageText">Spara</button> </div>
JScript:
$(function () { function SaveText(pageID, htmlText) { var retvalue = false; $.ajax({ async: false,
As it is now I create a JavaScript object and then stringify it, put it in a hidden textbox and my code behind can read this string. I then use JSON.NET to parse the string which works fine. I now try to use ajax to post it to my web service but have some issues with how to send the string. I have tried many ways but gets the common errors like
Invalid JSON primitive: myString.
So I checked this out [URL] and it works with hard coded values but I want to use a variable.
JavaScsript to create the object:
for (var i = 0; i < results.rows.length; i++) { var row = results.rows.item(i); var customer = new Object(); customer.id = row['id'] customer.name = row['name'] var customerString = JSON.stringify(customer); $.ajax({ type: "POST", url: "synchronise.asmx/synchroniseCustomers", data: "synchroniseCustomers: " + customerString, contentType: "application/json; charset=utf-8", dataType: "json", error: function (xhr, status) { alert("An error occurred: " + status); }, success: function (msg) { alert("success"); } }); }
WebMethod:
public void synchroniseCustomers(string customerString) { JObject o = JObject.Parse(customerString); string id = (string)o["id"]; string name = (string)o["name"];
If I use data: '{ FirstName: "Dave", LastName: "Ward" }'
in the example above it works but I wish to pass on a string instead.
I tried to pass a string value into a JavaScript function like below: <%= "'" + prop.property_description + "'") %>) But it does not seems to be the best option, is there a better way to do the above without concatenate the string values with "'"?
I have an containing a list of divs that jQuery turns into progress bars. On .ready, I build a list of all of these progress bars and for each one, call a webservice that gets a value indicating how full the progress bar should be. In order to do this, I need to pass the ID of the div to the web service.
Because the divs are inside a ListView, I manually set the id to be id="completionbar_<%# Eval("MilestoneID") %>"
However, when I pass this id into my web service, it comes up as "undefined" every time. When I view the source, it looks like it's set correctly.
The MyWebMethod returns an integer, and I want to set $(this).attr("id") of the jQuery object above to the returned integer. Basically, I'm trying to do the equivalent of an MVC Ajax.ActionLink...AjaxOptions {UpdateTargetID =...} However, I can't figure out how to get both a reference to $(this) as well as the returned value. For example, if I do:
I can succesfully manipulate the jQuery object, but obviously it doesn't have the return value from the MyWebMethod. Alternatively, the first code block with a method signature of onSuccessFunction(returnValue) has the correct return value from MyWebMethod, but no concept of the jQuery object I'm looking for. Am I going about this all wrong?
[URL] .... I am referring to the link given mentioned above, i want to save image details into database of each file, if i select two files i want to save filename in database in each row. ist file in 1 row , second file in next row with file name.
Well since it seems relatively difficult to send the object of a WebControl over JSON using jquery.ajax() I've decided to send the name of the control as a string because I know how to do that. Then I promptly realized that, from a web service, I don't actually know how to search for a control by ID name. Since its a service I can't seem to get Control.FindControl() to work. All I'm trying to do is call a databind() on my radcombobox.
For any of you that knows anything about asp.net/rad controls - I'm basically updating a database and want the radcombobox to be in sync with that database again after adding something, before I autoselect what was just added. Other than databind do i have to call anything to refresh that list?
and I have 3 DropDownList that refer below thread [URL] ...
I use cascadingdropdown for these 3 dropdownlist below are codes:
AND
[WebMethod] public CascadingDropDownNameValue[] GetCountries(string knownCategoryValues) { string query = "SELECT state FROM stateTest"; List countries = GetData(query); return countries.ToArray(); }
[Code] ....
1-DDLstate
2-DDLcity
3-DDLregion
at first I should select Item from DDLsate then DDlcity and at the end I should select Item from DDLregion
above code work correctly for ddlstate and ddlcity but it doesn't work for ddlregion...
I mean when I select Item from ddlcity in ddlregion shows:[Metod error500]
I am doing Ajax call using jQuery and my URL is like
http://localhost;3327/DummyAps/Demo.aspx
In Demo.aspx page i have a WebMethod, which i wanted to call. While doing jQuery ajax call i am giving the URL as "/DemoWebMethod", where "DemoWebMethod" is the Webmethod present in Demo.aspx page.
But while calling the WebMethod it is calling the URL http://localhost;3327/DummyAps/DemoWebMethod but i want to call http://localhost;3327/DummyAps/Demo.aspx/DemoWebMethod.
I know that changing the URL from "/DemoWebMethod" to "Demo.aspx/DemoWebMethod" will solve the problem but can i do it without writing that (because i have some problem with that).
I have defined a web service function for AutoCompleteExtender, but in addition to the two parameters passed "prefixText" and "count" i want to pass another parameter for a label in that function. So, how to define that ?
I tried using Ajax & Jquery for the following need, but not able to do...
I have Two Forms StringMain.aspx & Returner.aspx.... I have created 4 Divs at StringMain.aspx and a sample text "ToCheck" at First Div.. In the Returner.aspx form page load, i placed a label like this
I have set StringMain.aspx as default running page. So When i run StringMain.Aspx page,
the text i placed in the First Div "To Check" should concat with the label Text "hello" of Returner.aspx and display it together in the First Div of StringMain.aspx like this
byte[] b = YourByteArrayFromDb; File.WriteAllBytes(MyFilePath, b);
But I am receiving an exception "Access to the path is denied". How do I solve this using ASP.Net with C#? And is there any format to set the path as string?
Scenario : I am going to access external web service [ExternalWS] using AJAX. So obviously, need to create local proxy service [LocalProxyWS] first, which in turn will access the external web service. Now, the external service webmethod [Process] basically redirects the current page on our site to their site, does some work and then return back to our site.
What I want : I want that when the user clicks the button ('Process') on our site, it should open a new window and then starts executing the request on the new window, so that I can have the page on my website to be displayed permanently (which will poll a request every 15 seconds to the external service (via local proxy) for the status).
Local Proxy service which calls external service is as follows..
[ServiceContract(Namespace = "LocalProxy")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class LocalProxyToExternalService { [OperationContract] public void InitiateTransaction(string amount)
Basically, I am opening a new window from the button click and then want to process the new request in that new window, so that I can show the status to the user from the current page on my website So far, it opens the new window, but doesn't transfer the request on to that, but I get an error message in firebug as follows...
I am trying to call a web service function within my own ASP.net (code behind) using AJAX on the page.
Once i push the button to execute the JS/AJAX/codebehind - I got an error.
POST http://************/admin/Admin.aspx/getDBInformation 500 (Internal Server Error)
This is my code below that I am currently using:
Code: <WebMethod> _ Public Shared Function getDBInformation() As String loadDBData() Return JsonConvert.SerializeObject(dbInfo, System.Xml.Formatting.Indented) End Function End Class
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.
