I am trying to pass the value of TransactionNumber into the controller but I am getting an undefined result.
here is my code,
function getall()
{
$('#tbl-transaction').dataTable().fnDestroy();
$('#tbl-transaction').DataTable({
"ajax": {
"url": '/Admin/GetAllTransactions',
"type": "get",
"datatype" : "JSON"
},
"columns" :
[
{ data :"TransactionNumber"},
{ data: "PurposeOfVisit" },
{ data: "NameOfHostFromST" },
{ data: "TransactedBy" },
{
data: "id", "render" : function(data)
{
return '<button class= "btn btn-success" onclick = "get_details(' + data+ ')"> Details </button>';
}
}
]
})
}
function get_details(id,TransactionNumber)
{
window.location.href = '/Approver/Details/' + id + '?=' + TransactionNumber;
}
controller side
public ActionResult Details(int Id, string TN)
{
tbl_FSEWeb_Transaction tbl_FSEWeb_Transaction = db.tbl_FSEWeb_Transaction.Find(Id);
//var course = 0;
return View(tbl_FSEWeb_Transaction);
}
I'm using ASP.net mvc and ajax.
The structure of your URL is incorrect. Replace your javascript function with:
window.location.href = '/Approver/Details/?id=' + id + '&tn=' + TransactionNumber;
The initial parameters follow the format:
?<name>=<value>
Multiple parameters are then added with ampersands (&)

I've tried all other solutions pertaining to the problem, but still can't find what i'm missing for my code. Here's my AJAX() Code.
var group = JSON.stringify({ 'listofusers': listofusers });
console.log("listofusers : " + JSON.stringify({ 'listofusers': group }));
(Assuming I have my listofusers object ready, and yes i've checked the console and it has data inside.)
$.ajax({
contentType: 'application/json; charset=utf-8',
dataType: 'json',
type: "POST",
url: url,
data: group,
success: function (data) {
console.log("output : " + JSON.stringify(data));
//doSend(JSON.stringify(data));
//writeToScreen(JSON.stringify(data));
},
error: function (data) {
console.log("error : " + JSON.stringify(data));
},
});
Here's my Server Side Controller.
[HttpPost]
public IActionResult GetMesssage(List<UserModel> listofusers)
{
var g = listofusers;
}
Just a simple fetch from the controller, so I could verify that the data from client side has really been sent.
I've tried the [FromBody] attribute, but still no luck in fetching the data from the server-side.
Here is a working demo like below:
1.Model:
public class UserModel
{
public int Id { get; set; }
public string Name { get; set; }
}
2.View(remove Content-type):
<script>
var listofusers = [
{ id: 1, name: 'aaa' },
{ id: 2, name: 'bbb' },
{ id: 3, name: 'ccc' }
];
var group = { 'listofusers': listofusers };
console.log(group);
$.ajax({
dataType: 'json',
type: "POST",
url: "/home/GetMesssage",
data: group,
success: function (data) {
console.log("output : " + JSON.stringify(data));
},
error: function (data) {
console.log("error : " + JSON.stringify(data));
},
});
</script>
3.Console.log(group):
4.Result:
Update:
Another way by using json:
1.View(change group from JSON.stringify({ 'listofusers': listofusers });
to JSON.stringify(listofusers);):
<script>
var listofusers = [
{ id: 1, name: 'aaa' },
{ id: 2, name: 'bbb' },
{ id: 3, name: 'ccc' }
];
var group = JSON.stringify(listofusers);
console.log(group);
$.ajax({
contentType:"application/json",
dataType: 'json',
type: "POST",
url: "/home/GetMesssage",
data: group,
success: function (data) {
console.log("output : " + JSON.stringify(data));
},
error: function (data) {
console.log("error : " + JSON.stringify(data));
},
});
</script>
2.Controller(add FromBody):
[HttpPost]
public IActionResult GetMesssage([FromBody]List<UserModel> listofusers)
{
//...
}
You can try this one.
First stringify the parameter that you want to pass:
$.ajax({
url: url,
type: "POST",
data: {
listofusers: JSON.stringify(listofusers),
},
success: function (data) {
},
error: function (error) {
}
});
Then in your controller:
[HttpPost]
public IActionResult GetMesssage(string listofusers)
{
var jsonModel = new JavaScriptSerializer().Deserialize<object>(listofusers); //replace this with your deserialization code
}
What we're doing here is passing your object as a string then deserializing it after receiving on the controller side.
Hope this helps.
I found the solution to my problem guys, but I just want a clarification that maybe there's a work around or another solution for this one.
I've studied the data passed by "JSON.stringify();" from AJAX() and it's somehow like this.
"[[{\"ID\":0,\"UserID\":1014,\"Level\":\"support\",\"Department\":\"\",\"Facility\":\"Talisay District Hospital\",\"Firstname\":\"Joseph\",\"Middlename\":\"John\",\"Lastname\":\"Jude\",\"LoginStatus\":false,\"IPAddress\":\"192.168.110.47:12347\"},{\"ID\":0,\"UserID\":1014,\"Level\":\"support\",\"Department\":\"\",\"Facility\":\"Talisay District Hospital\",\"Firstname\":\"Joseph\",\"Middlename\":\"John\",\"Lastname\":\"Jude\",\"LoginStatus\":false,\"IPAddress\":\"192.168.110.47:15870\"}]]"
to which I was wondering that if the JSON format is a factor in parsing the data from the controller side. (Which of course is stupid since there's only one JSON format. (or maybe there's another, if there is, can you please post some source for reference.))
so I tried Serializing a Dummy Data in my model in "JsonConvert.Serialize()" Method and the output JSON data is like this.
[{"ID":0,"UserID":1014,"Level":"support","Department":"","Facility":"Talisay District Hospital","Firstname":"Joseph","Middlename":"John","Lastname":"Jude","LoginStatus":false,"IPAddress":"192.168.110.47:12347"},{"ID":0,"UserID":1014,"Level":"support","Department":"","Facility":"Talisay District Hospital","Firstname":"Joseph","Middlename":"John","Lastname":"Jude","LoginStatus":false,"IPAddress":"192.168.110.47:16709"}]
and I tried sending the output JSON Data from JsonConvert.Serialize() Method to controller via AJAX() and it worked! And I feel so relieved right now as this problem was so frustrating already.
If there's something wrong with what I found, please respond with what might be wrong or correct. Thank you!
i am using Datatable jquery and i would like to call delete action on every row inside a button ...how can i redirect to action method delete of the controllers User with the right parameter?
var datatableVariable = $('#myTable').DataTable({
....
columns: [
...column definition...{
data: null,
render: function(data, type, row) {
return "<a href='#' class='btn btn-danger' onclick=DeleteData('" + row.id + "'); >Delete</a>";
}
},
],
});
function DeleteData(id) {
if (confirm("Are you sure you want to delete ...?")) {
Delete(id);
} else {
return false;
}
}
function Delete(id) {
var url = '#Url.Content("~/")' + "Users/Delete";
$.post(url, {
ID: id
}, function(data) {
if (data) {
oTable = $('#myTable').DataTable();
oTable.draw();
} else {
alert("Something Went Wrong!");
}
});
}
I assume you just want to call your action method in the controller.
Use Ajax
$.ajax({
type: "POST",
url: "/Users/Delete",
data: { ID: id},
success: {
},
});
I have the below custom button added to my navigation pager, but i want it to look at what i multi selected and send it to the JQGrid's editurl for processing which is a ASHX.CS page
But i can't make sense of the documentation when it comes to custom button
I can get it call a local function with onClickButton: customButtonClicked but it doesn't send the data like the EDIT button does
In the end what i want to do it select multiple rows and press a button on the navbar and approve all the selected records
// add first custom button
$('#jQGrid').navButtonAdd('#jQGridPager',
{
buttonicon: "ui-icon-mail-closed",
title: "Send Mail",
caption: "Send Mail",
position: "last",
editData: {
WrkId: function () {
var sel_id = $('#jQGrid').jqGrid('getGridParam', 'selarrrow');
var value = "";
for (var a = 0; a < sel_id.length; a++) {
value = value + $('#jQGrid').jqGrid('getCell', sel_id[a], 'wrkid') + ',';
}
return value;
},
CurrentUser: function () {
return '<% =System.Web.HttpContext.Current.User.Identity.Name %>';
}
},
afterSubmit: function (response, postdata) {
if (response.responseText == "") {
$("#jQGrid").trigger("reloadGrid", [{ current: true }]);
return [false, response.responseText]
}
else {
$(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid')
return [true, response.responseText]
}
}
}
);
using a few different words (how to manually post data to server json) i was able to find a snippet of an ajax code that made more sense (i'm sure i came across this before but as someone who has no jquery experience i didn't recognize it)
but the below sends to the C# handler page the data in a JSON string that was processable, had to use dynamic to read it in but it worked, couldn't get it to not return an error even though there was no error, so i used the complete: instead of success: and then called the trigger to reload the JQGrid
Final Code:
$('#jQGrid').navButtonAdd('#jQGridPager',
{
buttonicon: "ui-icon-check",
title: "Approve all selected entries",
caption: "Approve",
position: "last",
onClickButton: function () {
var sel_id = $('#jQGrid').jqGrid('getGridParam', 'selarrrow');
var value = "";
for (var a = 0; a < sel_id.length; a++) {
value = value + $('#jQGrid').jqGrid('getCell', sel_id[a], 'wrkid') + ',';
};
$.ajax({
type: "POST",
url: "AdministrationHandler.ashx?oper=approve",
data: JSON.stringify({
WrkId: value,
CurrentUser: "<% =System.Web.HttpContext.Current.User.Identity.Name %>"
}),
dataType: "json",
contentType: "application/json; charsset=utf-8",
complete: function (xhr, x) {
if (xhr.responseText.toUpperCase().indexOf("SUCCESS") >= 0) {
alert('Success!\n' + xhr.responseText);
}
else {
alert('Failed!\n' + xhr.responseText + '\n' + x);
};
$("#jQGrid").jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid');
}
})
}
});
C# Code
try
{
String postData = new System.IO.StreamReader(context.Request.InputStream).ReadToEnd();
var data = JsonConvert.DeserializeObject<dynamic>(postData);
Approve(data.WrkId.ToString(), data.CurrentUser.ToString());
strResponse = "Employee records successfully approved";
}
catch
{
strResponse = "Employee records not approved";
}
context.Response.Write(strResponse);
I am very much new in MVC. I have javascript function that reads xml string and displays various values. One of the element in XML is in encrypted form. I have written method in controller that will return decrypted string but I am not able to call that method inside my javascript method using ajax. Below the code of controller method and javascript code.
[HttpPost]
public ActionResult DecryptMessage(string message)
{
string decryptedMessage= Encryption.DecryptData(message);
return Json(decryptedMessage);
}
part of Javascript code
if ((x[i].nodeName).toUpperCase() == "MESSAGE" ) {
//alert(childnd.nodeValue);
$.ajax({
type: "POST",
data: { value: childnd.nodeValue },
url: "/QueryController/DecryptMessage",
dataType:"string",
Success: function (result) {
if (result > 0) {
stringDetails = stringDetails + '<br><strong>Value:</strong>' + result + '<br>';
}
})
}
I am not able to figure out what is wrong.
Since this is your URL that you work on: localhost/LogViewerPortal/Query/Index, your AJAX should fire to the same URL. Also, change Success to success:
if ((x[i].nodeName).toUpperCase() == "MESSAGE" ) {
//alert(childnd.nodeValue);
$.ajax({
type: "POST",
data: { message : childnd.nodeValue },
url: "/LogViewerPortal/Query/DecryptMessage",
success: function (result) {
if (result) {
stringDetails = stringDetails + '<br><strong>Value:</strong>' + result + '<br>';
}
})
}
And if you want to return a string from your controller, you could change to:
[HttpPost]
public ActionResult DecryptMessage(string message)
{
string decryptedMessage= Encryption.DecryptData(message);
return Content(decryptedMessage);
}
this is related to my previous question about jqgrid. im doing now a search button that would search my inputed text from the server and display those data (if there is) in the jqgrid. Now, what i did is i create a global variable that stores the filters. Here's my javascript code for my searching and displaying:
filter = ''; //this is my global variable for storing filters
$('#btnsearchCode').click(function(){
var row_data = '';
var par = {
"SessionID": $.cookie("ID"),
"dataType": "data",
"filters":[{
"name":"code",
"comparison":"starts_with",
"value":$('#searchCode').val(),
}],
"recordLimit":50,
"recordOffset":0,
"rowDataAsObjects":false,
"queryRowCount":true,
"sort_descending_fields":"main_account_group_desc"
}
filter="[{'name':'main_account_group_code','comparison':'starts_with','value':$('#searchCode').val()}]";
$('#list1').setGridParam({
url:'json.php?path=' + encodeURI('data/view') + '&json=' + encodeURI(JSON.stringify(par)),
datatype: Settings.ajaxDataType,
});
$('#list1').trigger('reloadGrid');
$.ajax({
type: 'GET',
url: 'json.php?' + $.param({path:'data/view',json:JSON.stringify(par)}),
dataType: Settings.ajaxDataType,
success: function(data) {
if ('error' in data){
showMessage('ERROR: ' + data["error"]["msg"]);
}
else{
if ( (JSON.stringify(data.result.main.row)) <= 0){
alert('code not found');
}
else{
var root=[];
$.each(data['result']['main']['rowdata'], function(rowIndex, rowDataValue) {
var row = {};
$.each(rowDataValue, function(columnIndex, rowArrayValue) {
var fldName = data['result']['main']['metadata']['fields'][columnIndex].name;
row[fldName] = rowArrayValue;
});
root[rowIndex] = row;
row_data += JSON.stringify(root[rowIndex]) + '\r\n';
});
}
alert(row_data); //this alerts all the data that starts with the inputed text...
}
}
});
}
i observed that the code always enter this (i am planning this code to use with my other tables) so i put the filter here:
$.extend(jQuery.jgrid.defaults, {
datatype: 'json',
serializeGridData: function(postData) {
var jsonParams = {
'SessionID': $.cookie("ID"),
'dataType': 'data',
'filters': filter,
'recordLimit': postData.rows,
'recordOffset': postData.rows * (postData.page - 1),
'rowDataAsObjects': false,
'queryRowCount': true,
'sort_fields': postData.sidx
};
return 'json=' + JSON.stringify(jsonParams);
},
loadError: function(xhr, msg, e) {
showMessage('HTTP error: ' + JSON.stringify(msg) + '.');
},
});
now, my question is, why is it that that it displayed an error message "Server Error: Parameter 'dataType' is not specified"? I already declared dataType in my code like above but it seems that its not reading it. Is there anybody here who can help me in this on how to show the searched data on the grid?(a function is a good help)
I modified your code based on the information from both of your questions. As the result the code will be about the following:
var myGrid = $("#list1");
myGrid.jqGrid({
datatype: 'local',
url: 'json.php',
postData: {
path: 'data/view'
},
jsonReader: {
root: function(obj) {
var root = [], fields;
if (obj.hasOwnProperty('error')) {
alert(obj.error['class'] + ' error: ' + obj.error.msg);
} else {
fields = obj.result.main.metadata.fields;
$.each(obj.result.main.rowdata, function(rowIndex, rowDataValue) {
var row = {};
$.each(rowDataValue, function(columnIndex, rowArrayValue) {
row[fields[columnIndex].name] = rowArrayValue;
});
root.push(row);
});
}
return root;
},
page: "result.main.page",
total: "result.main.pageCount",
records: "result.main.rows",
repeatitems: false,
id: "0"
},
serializeGridData: function(postData) {
var filter = JSON.stringify([
{
name:'main_account_group_code',
comparison:'starts_with',
value:$('#searchCode').val()
}
]);
var jsonParams = {
SessionID: $.cookie("ID"),
dataType: 'data',
filters: filter,
recordLimit: postData.rows,
recordOffset: postData.rows * (postData.page - 1),
rowDataAsObjects: false,
queryRowCount: true,
sort_descending_fields:'main_account_group_desc',
sort_fields: postData.sidx
};
return $.extend({},postData,{json:JSON.stringify(jsonParams)});
},
loadError: function(xhr, msg, e) {
alert('HTTP error: ' + JSON.stringify(msg) + '.');
},
colNames:['Code', 'Description','Type'],
colModel:[
{name:'code'},
{name:'desc'},
{name:'type'}
],
rowNum:10,
viewrecords: true,
rowList:[10,50,100],
pager: '#tblDataPager1',
sortname: 'desc',
sortorder: 'desc',
loadonce:false,
height: 250,
caption: "Main Account"
});
$("#btnsearchCode").click(function() {
myGrid.setGridParam({datatype:'json',page:1}).trigger("reloadGrid");
});
You can see the code live here.
The code uses datatype:'local' at the beginning (at the 4th line), so you will have no requests to the server if the "Search" button is clicked. The serializeGridData the data from the postData parameter of serializeGridData will be combined with the postData parameter of jqGrid (the parameter "&path="+encodeURIComponent('data/view') will be appended). Additionally all standard jqGrid parameters will continue to be sent, and the new json parameter with your custom information will additionally be sent.
By the way, if you want rename some standard parameters used in the URL like the usage of recordLimit instead of rows you can use prmNames parameter in the form.
prmNames: { rows: "recordLimit" }
