Sending javaScript array to server side c# via web service
call
I wanted to send a collection of attributers for a set of
textbox input html controls to the server side via an AJAX call:
Collect the desired elements and place certain properties in
an array:
var inputs = new Array();
$("[class^=txtEdit]").filter(":input").each(function () {
var i = { 'ClassName': $(this).attr("class"), 'Id': $(this).attr("id"), 'Val': $(this).val() };
inputs.push(i);
});
Make the AJAX call:
var serviceUrl = '..//Tools.asmx/SaveEdits';
$.ajax({
type: "POST",
//data: JSON.stringify(inputs),
data: '{ "elements":' + JSON.stringify(inputs) + '}',
contentType: "application/json; charset=utf-8",
url: serviceUrl,
dataType: "json",
success: function (response) {
if (response.d) {
//TODO: rebind
}
else {
alert("Save Edits Failed");
}
},
error: function (response) {
alert("failed service call" + serviceUrl);
}
});
Container class on server:
public class HtmlInput
{
public string ClassName { get; set; }
public string Id { get; set; }
public string Val { get; set; }
public HtmlInput()
{
}
public HtmlInput(string className, string id, string val)
{
this.ClassName = className;
this.Id = id;
this.Val = val;
}
}
The web method:
///
/// Saves all the inputs (items, appOverdies) using services
///
/// colecton of html inputs
///error string
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string SaveEdits(HtmlInput[] elements)
{
string ret = string.Empty;
try
{
foreach (HtmlInput txt in elements)
{
//DO some stuff
}
return ret;
}
catch (Exception e)
{
//TODO: log e.message etc.
return ret += e.Message;
}
}
