Data Controls :: Pass JSON Data Object From JQuery AJAX To WebMethod
May 7, 2015
I want to send single json object with nested arrays through jquery ajax method.
In Code
In jquery ajax i am passing LeaveRuleMaster a single json object which holds some properties (Leavetypeid, Leavename, Leavestatus and nested array LeaveRulespecific.
In vb.net code i can receive the value of properties(Leavetypeid,Leavename,Leavestatus)
but i am receiving the LeaveRuleSpecific as nothing.
Based on the following link i tried this [URL] .....
I am trying to retrieve asp.net C# List method in JavaScript by referring Send-and-receive-JavaScript-Array-to-Web-Service-Web-Method-using-ASP.Net-AJAX ..My Code as below
Javascript
<script type = "text/javascript"> function GetAllSVGData() { PageMethods.GetSvgElements(OnSuccessSVGElements); } function OnSuccessSVGElements(response) {
[code]....
My problem is JavaScript function OnSuccessSVGElements is not firing. When I put breakpoints in it is working fine in C#. C# Method Working But Alerts in javascript not working.
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.
I have a web Method in my C# that is called via Jquery ajax method. The web method should return an object back to the Jquery which will be used to populate. I have tried returning a JsonResult object, the actual object and nothing seems to work! I'm not using MVC (Unfortunately). Is there a way that I can return an object from my web method which can be used by my AJAX method? here is the link for my JQuery AJAX method [URL]
Basically, my question is: how do I specify optional parameters to a WebMethod when providing JSON data?
I know I can reduce the parameters down to just the required values, and then use HttpContext.Request.Params to read the values of optional paramaters, but I would have thought the way I have tried here should have worked.
EDIT
The XMLHttpRequest.responseText value for the error is:
Invalid JSON primitive: staffcode.
This is throwing me even more off the scent of the problem :(
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 am binding Gridview using json (first Gridview),which have some column with linkbutton. I want to bind other gridview(second Gridview) using json on click of Linkbutton inside first gridview . how to fire json on linkbutton click event ?
I want to add gridview row data into to data base I am doing it perfectly.My problem is that want all gridview row data save and then web method should be called but in my cause one gridview data save in array then call webmethod,then other row data save in array then call webmethod called this process should be so on.But I want it webmethod should be called when all gridview row save in array.
Follwing code
Jquery <script type="text/javascript"> $(function () { $("[id*=btnSubmit]").bind("click", function () { var Customer = {};
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 have the following web method , no success on return a correct Json format.
[Code]....
GetAll() return list of type "Company" POCO classes.
The web method complaint type "Company" could not cast to object. However I could not just return the Company type because client side Json only accept its 2 properties -"CompanyName", "ID" and I want to keep it that way.
Of cause, I had tried create a CompanyDTO which only have those two properties, but same error - "Unable to cast object of type..."
How should I modify in my web method to make it able to return a list of partial "Company" type in Json format?
i am new in json script.am trying to convert the database table value into json using asp.net with c#.here, am also send the response to asp.net client side.but am not receiving any response from server side.
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?
I am creating one Json array object and trying to pass it in MVC controller action method but i am getting null paramerter; as per my knowledge json only maps .net primitive datatypes.... so it assign null value.
Note: when i have look at request object i found that there are three parameter of created array. But how to get that value as parameter of function?
