How to POST Array to Web Service with AJAX

Question

I am working on a Google Chrome Extension. I have string array and I need post my array to web service with ajax and return again. Here is my code:

 var data = {};
data.param1 = words; // my string array

$.ajax({
    data: JSON.stringify( data ),
    dataType: "json",
    url: 'http://localhost:49242/Service.asmx',
    type: "POST",
    contentType: "application/json; charset=utf-8",
    success: function (result) {
        alert("basarili");
    },
    failure: function(errMsg) {
    alert(errMsg);
}
});

Service:

public string example(string[] param1) {

        string result = param1[0];
        return result;
    }

I am not getting an error but this code is not working. How can I solve?

do you have debug your code step by step ? do you have see what you send, what you get ? — Aristos

var data = {};
data.param1 = words; // my string array

$.ajax({
    data: {param1: data.param1},
    url: 'http://localhost:49242/Service.asmx',
    type: "POST",
    success: function (result) {
        alert("basarili");
    },
    failure: function(errMsg) {
        alert(errMsg);
    }
});

Try using Json Encode while returning string in the Service file.

can you write an example?

Namrata Yande Over a year ago

For example, in your Service file you can convert string to JSON format and then return it. public string example(string[] param1) { string result = param1[0]; var serializer = new JavaScriptSerializer(); return serializer.Serialize(new { Name = result }); } Hope this helps you.

I have given similar answer in

As per my observation

var data = {};
data.param1 = ["String1","String2"]; // my string array

$.ajax({
    data: JSON.stringify( data ),
    dataType: "json",
    url: 'http://localhost:49242/Service.asmx/example',//Missing Method Name 
    type: "POST",
    contentType: "application/json; charset=utf-8",
    success: function (result) {
        alert(result.d);
    },
    failure: function(errMsg) {
    alert(errMsg);
}
});

and .aspx

  <form id="form1" runat="server">
    //rest is omitted 
    <asp:scriptmanager ID="Scriptmanager1" runat="server">
        <Services>
            <asp:ServiceReference runat="server" Path="~/WebService1.asmx"/>

        </Services>

    </asp:scriptmanager>
    </form>

and

[System.Web.Script.Services.ScriptService]//This is must
public string example(string[] param1) {

        string result = param1[0];
        return result;
    }

I don't have a web form (.aspx) . Is it a problem?

Syed Mhamudul Hasan Over a year ago

I tested in jQuery .It will work with out scriptmanager.The problem is in your method .check the ajax call .

Did ur web service works perfectly? What does ur result show? Paste ur word object?

pseudocode Over a year ago

Service is working perfectly. When I writed a string manually in url, return a value correctly. But I can't send a variable to service. I think the problem is here: $.ajax({ data: JSON.stringify(data), dataType: 'json', url: "Service.asmx/kok_bul", type: "POST", contentType: "application/json; charset=utf-8", success: function (result) { alert(result); }, failure: function (errMsg) { alert(errMsg); } });
