I'm trying to retrieve posted JSON data on server side in an ASHX file via this code string strrequest = context.Request["OrderInfo"]; but it always return null. What Am I doing wrong?
I'm new to Jquery, JSON and MVC, and am trying to create a json object that contains AD info from an AD query. The ad query is working fine and returning data and I have 2 overloaded implementations of it.
#1 is a method from an older .net app that builds and returns a datatable that we bound to a grid view control
#2 was a modification of #1 that returns a System.Collections.Generic.List<> type. #2 returns data ok and i can display a table in the MVC view
however, I'd like to get the data results into a json object so i can bind it to a jqGrid object that has similar functionality to the old .Net server controls (Delete, Update, Sort) Here's the new method that's part of a C# static class:
[Code]....
Like I said...I'm new to this way of doing web development, so I'm not sure how to even approach getting this data into a json object.
I was trying to send a Batch request with O-data framework given below is the code sequence.
updateService = new Sys.Data.OpenDataServiceProxy("http://localhost/myservice.svc"); actionSequence = updateService.createActionSequence(); actionSequence.addUpdateAction(newWr, workRequest.__metadata.uri); try { actionSequence.execute( function () { alert("Success"); }, function (error) { alert(error._message); } ); } catch (e) { }
but this is failing because on response in the end i am geting some extra sections such as undefined ..given below is the response that i am geting in the end u can find the last 3-4 lines and junk data. which is
i have few textbox on the form and when the user submit i want to capture the data and insert into db
here is what my code looks like
beforeSubmit: function(data) { // called just before the form is submitted var item = $("[id$='item']"); var category = $("[id$='category']"); var record = $("[id$='record']");
I want to send single json object with nested arrays through jquery ajax method.

for SEO purposes, instead of refreshing the page every click of a product, is it possible to click on the product and when the server comes back with the response, to change the URL of the page to reflect the new link to information currently on page?
point is to have ajax redraw the product details portion of the page but have SEO friendly url's displayed so if people want to bookmark the currently selected product, it will bookmark the right url instead of the generic one to access the products page..
For example... here's my entry point:
Products.aspx
product1product2product3 If I were to click product1, the request goes to the server with roducts.aspx?id=product1 but the url is still products.aspx on the response meaning that when people bookmark the product1 item, and they send the link to a friend, the friend always gets the generic product.aspx page.
I'm trying to get around this without refreshing the full page (postback).
If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
I have the following code where the function codeaddress geocodes the text feild value and returns geocoded value , geocoded value is stored in variable example ,how will i return the variable v2 to the function call and post to asmx webservice.
We have an exisiting Web Service which receives SOAP requests and returns the data accordingly. However, we have a new project which requires the same information but the Android SDK doesn't support SOAP so we need to use JSON. As JSON is just a data container format, I need to write a new module to replace the SOAP WSDL which receives a querystring from the Android app and then processes the data and returns it in a JSON packet. The problem is that having never used JSON I'm unsure as to how I return the data to the app in JSON format. Does anyone have any examples I can look at in VB.Net or C#?
I'm doing an jQuery AJAX POST call to a webmethod, which is working fine. If I'm passing data from the AJAX call, I normally get the data in the webmethod via webmethod parameters.
JavaScript Code: $.ajax({"dataType": "json","contentType": "application/json","type": "POST","url": "Default.aspx/GetStuff","data": JSON.stringify({"a":"data1","b":2}),"success": function (msg) { console.log(msg.d);}}); C# Code: [WebMethod]public static object GetStuff(string a, int b){ }
Is there any way I can get the data as a Dictionary or some other object, instead of having to put in individual parameters to the GetStuff() web method for each data param? It's a POST request so nothing is in Request.QueryString, and Request.Params/Request.Form doesn't contain it either.
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'm trying to save some content whenever a button/hyperlink is clicked using jquery.ajax (Using Asp.net 3.5). The logic is as follows:
Through .bind in jquery I bind my own method(MakeLog) to a button click or hyperlink click. The click events of button/hyperlink contain nothing, I need to use .bind for selective controls.Now we have a button whose click event will fire a method, say MakeLog.Code snippet for MakeLog is as follows:
This works fine in IE but in Firefox this is not sending the data back as expected.I tried to identify the issue and came across the following: http://stackoverflow.com/questions/3522944/jquery-ajax-calls-async-false-vs-async-true .What I understand is that, whenver page is redirecting/reloading due to button click or hyperlink click the async call is not working properly.
