how to extract URL parameter from POST request in nodejs and expressjs - ajax

REQUEST URL http://localhost:9090/rest-api/fetchDetailedProductInfo?prodId=1&tempId=123
fetchDetailedProductInfo: function (prodId) {
var self = this;
var URL = 'http://localhost:9090/rest-api/fetchDetailedProductInfo'
$.ajax({
url: URL,
dataType: 'json',
contentType:'json',
type:'GET',
data: {
'prodId':prodId,
'tempId':123
},
success:function(responce) {
self.renderUI(responce.json);
},
error: function (err) {
console.log('ERROR',err)
}
});
},
# SERVER SIDE
router.get('/rest-api/fetchDetailedProductInfo', function (req, res) {
var prodId = req.param('prodId');
var tempId = req.param('tempId');
res.send(prodId + '----' + tempId);
}

I think you confused with req.params and req.query. Here is link to another question
Use req.query
var prodId = req.query.prodId;
var tempId = req.query.tempId;

Is there a way to show "Loading data.." option in Rally Grid(ext JS) while making the Ajax request to load the data?

I am trying to set the message to "Data Loading.." whenever the data is loading in the grid. It is working fine if I don't make an Ajax call. But, when I try to make Ajax Request, It is not showing up the message "Loading data..", when it is taking time to load the data. Can someone please try to help me with this.. Thanks in Advance.
_loadData: function(x){
var that = this;
if(this.project!=undefined) {
this.setLoading("Loading data..");
this.projectObjectID = this.project.value.split("/project/");
var that = this;
this._ajaxCall().then( function(content) {
console.log("assigned then:",content,this.pendingProjects, content.data);
that._createGrid(content);
})
}
},
_ajaxCall: function(){
var deferred = Ext.create('Deft.Deferred');
console.log("the project object ID is:",this.projectObjectID[1]);
var that = this;
console.log("User Reference:",that.userref,this.curLen);
var userObjID = that.userref.split("/user/");
Ext.Ajax.request({
url: 'https://rally1.rallydev.com/slm/webservice/v2.0/project/'+this.projectObjectID[1]+'/projectusers?fetch=true&start=1&pagesize=2000',
method: 'GET',

'Content-Type': 'application/json'
},
success: function (response) {
console.log("entered the response:",response);
var jsonData = Ext.decode(response.responseText);
console.log("jsonData:",jsonData);
var blankdata = '';
var resultMessage = jsonData.QueryResult.Results;
console.log("entered the response:",resultMessage.length);
this.CurrentLength = resultMessage.length;
this.testCaseStore = Ext.create('Rally.data.custom.Store', {
data:resultMessage
});
this.pendingProjects = resultMessage.length
console.log("this testcase store:",resultMessage);
_.each(resultMessage, function (data) {
var objID = data.ObjectID;
var column1 = data.Permission;
console.log("this result message:",column1);
if(userObjID[1]==objID) {
console.log("obj id 1 is:",objID);
console.log("User Reference 2:",userObjID[1]);
if (data.Permission != 'Editor') {
deferred.resolve(this.testCaseStore);
}else{
this.testCaseStore = Ext.create('Rally.data.custom.Store', {
data:blankdata

deferred.resolve(this.testCaseStore);
}
}
},this)
},
failure: function (response) {
deferred.reject(response.status);
Ext.Msg.alert('Status', 'Request Failed.');
}
});
return deferred;
},
The main issue comes from your Ajax request which is using
async:false
This is blocking the javascript (unique) thread.
Consider removing it if possible. Note that there is no guarantee XMLHttpRequest synchronous requests will be supported in the future.
You'll also have to add in your success and failure callbacks:
that.setLoading(false);

ajax call returning promis and resolve it by the calling function to its value

By now i read somewhere around 6 pages containing documentations and stackoverflow answers but I don't get the method.
My function is by now after reading all the stuff built like this:
async function getFToken(postId){
const response = await $.ajax({
type: "POST",
url: ajax_object.ajax_url,
data:{
action:'get_f_token',
postId: postId,
},
success:function(response) {
}
});
return response;
}
and in my other function is like this:
function getFeedback(postId){
$(".show_company").hide();
$(".show_feedback").show();
$.ajax({
type: "POST",
dataType: "text json",
url: ajax_object.ajax_url,
data:{
action:'get_feedback',
postId: postId,
},
success:function(response) {
var postTitle = '';
for (i in response) {
postTitle += "<h1>" + response[i].post_title + "</h1><br/><br/>" + response[i].ID ;
var test = getFToken(387);
alert(Promise.resolve(test));
};
$("#result").html(postTitle);
}
});
}
is there any chance, that this is a bigger issue because i call a async in another Ajax call trying to retrieve the value? I'm trying to get the string from the first ajax call and hand it to the second function in the ajax call to attach it to the posts i retrieve from WordPress
The alert is giving me [object Promise] but how do i get the value passed from the php script?
php-scrtipt:
//get fToken from specific feedbacks
add_action( 'wp_ajax_get_f_token', 'get_f_token' );
function get_f_token() {
if(isset($_POST['postId'])){
$postId = $_POST['postId'];
}
$fToken = get_post_meta($postId, 'fToken', true);
echo $fToken;
wp_die();
}
Don't use success callbacks when you can use async/await:
async function getFToken(postId) {
return $.ajax({
type: "POST",
url: ajax_object.ajax_url,
data: {
action: 'get_f_token',
postId: postId,
}
});
}
async function getFeedback(postId) {
$(".show_company").hide();
$(".show_feedback").show();
const response = await $.ajax({
// ^^^^^
type: "POST",
dataType: "text json",
url: ajax_object.ajax_url,
data: {
action: 'get_feedback',
postId: postId,
}
});
let postTitle = '';
for (const i in response) {
postTitle += "<h1>" + response[i].post_title + "</h1><br/><br/>" + response[i].ID ;
const test = await getFToken(387);
// ^^^^^
alert(test); // no Promise.resolve, you don't want to alert a promise
}
$("#result").html(postTitle);
}

How to implement Antiforgerytokens with partial views in mvc4?

I am trying to implement antiforgerytoken in my project. I am able to implement it when making ajax call below.
function docDelete(id) {
var _upload_id = $("#docId").val();
var _comments = $("#name").val();
var forgeryId = $("#forgeryToken").val();
$("#dialog-form").dialog("open");
$.ajax({
type: 'GET',
cache: false,
url: '/DeleteDocument/Delete',
dataType: 'json',
headers: {
'VerificationToken': forgeryId
},
data: { _upload_id: _upload_id, _comments: _comments },
success: function (data) {
$('#dialog-form').dialog('close');
$('#name').val('');
$('#dvSuccess').val(data);
Getgridata(data);
}
});
}
above code works fine. But in some cases i am making ajax request as below.
var forgeryId = $("#forgeryToken").val();
function GetGrid() {
$.ajax(
{
type: "GET",
dataType: "html",
cache: false,
url: '/Dashboard/GetGridData',
headers: {
'VerificationToken': forgeryId
},
success: function (data) {
$('#dvmyDocuments').html("");
$('#dvmyDocuments').html(data);
}
});
}
Above code does not send any token to below method.
private void ValidateRequestHeader(HttpRequestBase request)
{
string cookieToken = string.Empty;
string formToken = string.Empty;
string tokenValue = request.Headers["VerificationToken"]; // read the header key and validate the tokens.
if (!string.IsNullOrEmpty(tokenValue))
{
string[] tokens = tokenValue.Split(',');
if (tokens.Length == 2)
{
cookieToken = tokens[0].Trim();
formToken = tokens[1].Trim();
}
}
AntiForgery.Validate(cookieToken, formToken); // this validates the request token.
}
}
In layout.cshtml i have implmented code to get token.
<script>
#functions{
public string GetAntiForgeryToken()
{
string cookieToken, formToken;
AntiForgery.GetTokens(null, out cookieToken, out formToken);
return cookieToken + "," + formToken;
}
}
</script>
<input type="hidden" id="forgeryToken" value="#GetAntiForgeryToken()" />
The variable tokenValue catching null each time. So what i understood is through headers i am not able to send token value. I tried many alternatives. So anyone suggest me how can i overcome this issue? Thank you in advance.
I tried as below still i am getting null value.
var token = $('[name=__RequestVerificationToken]').val();
var headers = {};
headers["__RequestVerificationToken"] = token;
alert(token);
var forgeryId = JSON.stringify($("#forgeryToken").val());
function GetGrid() {
$.ajax(
{
type: "GET",
dataType: "html",
cache: false,
url: '/Dashboard/GetGridData',
cache: false,
headers: headers,
success: function (data) {
$('#dvmyDocuments').html("");
$('#dvmyDocuments').html(data);
}
});
}

Ajax Post method issue with passing huge data

folks
we are facing a strange issue with jquery ( 1.8.3) and we are using cakePHP
as per the image
Our assumption is we are sending the data( about 500 +) with ajax call in POST method.
we are having this issue in all the major browsers.
as above( in chrome) , we are getting this error in console we passed 618 destinations in ajax call.
let us know the work around to solve this problem.
My ajax call is as below
function validate_test() {
$("#btn1").empty();
var ele = document.getElementById('frm_searchDateFrom').value;
var ele2 = document.getElementById('frm_searchDateTo').value;
var sub_url = '<?php echo $this->Html->url('/', true); ?>';
var url = sub_url + "admin/reports/check_originator/" + ele +"/"+ ele2 +"/"+ $("#destination").val();
alert(url);
jQuery.ajax({
type: "POST",
datatype: "json",
url: url,
success: function(data)
{
var el = $("select#btn1").multiselect();
var d;
var results=data.split(",");
for(d=0;d<results.length;d++) {
var d;
var v = results[d], opt = $('<option />', {
value: v,
text: v
});
opt.appendTo( el );
el.multiselect('refresh');
}
}
})
}
In your JQuery Ajax method instead of posting all those details as url query para meter send by wrapping those details in a object.
function validate_test() {
$("#btn1").empty();
var ele = document.getElementById('frm_searchDateFrom').value;
var ele2 = document.getElementById('frm_searchDateTo').value;
var sub_url = '<?php echo $this->Html->url('/', true); ?>';
var url = sub_url + "admin/reports/check_originator/";
var formdata=ele +"/"+ ele2 +"/"+ $("#destination").val();//put form data's in an object
alert(url);
jQuery.ajax({
type: "POST",
datatype: "json",
data:formdata,//send the form data object in post
url: url,
success: function(data)
{
var el = $("select#btn1").multiselect();
var d;
var results=data.split(",");
for(d=0;d<results.length;d++) {
var d;
var v = results[d], opt = $('<option />', {
value: v,
text: v
});
opt.appendTo( el );
el.multiselect('refresh');
}
}
})
}

MVC3 and Twitter Bootstrap TypeAhead without plugin

I have gotten TypeAhead to work properly with static data and am able to call my controller function properly and get data but it is either A: Not parsing the data properly or B: The TypeAhead is not set up correctly.
JavaScript :
<input type="text" id="itemSearch" data-provide="typeahead" value="#ViewBag.Item" name="itemSearch"/>
$('#itemSearch').typeahead({
source: function (query, process) {
parts = [];
map = {};
$.ajax({
url: '#Url.Action("MakePartsArray")',
dataType: "json",
type: "POST",
data: {query: query},
success: function (data) {
$.each(data, function (i, part) {
map[part.description] = part;
parts.push(part.description);
});
typeahead.process(parts);
}
});
},
updater: function (item) {
selectedPart = map[item].itemNumber;
return item;
},
matcher: function (item) {
if (item.toLowerCase().indexOf(this.query.trim().toLowerCase()) != -1) {
return true;
}
},
sorter: function (items) {
return items.sort();
},
highlighter: function (item) {
var regex = new RegExp('(' + this.query + ')', 'gi');
return item.replace(regex, "<strong>$1</strong>");
}
});
Controller :
public ActionResult MakePartsArray(string query)
{
var possibleItem = query.ToLower();
var allItems = Db.PartInventorys.Where(l => l.ItemNumber.Contains(possibleItem)).Select(x => new { itemNumber = x.ItemNumber, description = x.Description });
return new JsonResult
{
ContentType = "text/plain",
Data = new { query, total = allItems.Count(), suggestions = allItems.Select(p => p.itemNumber).ToArray(), matches = allItems, },
JsonRequestBehavior = JsonRequestBehavior.AllowGet
};
}
In my controller I see the data being retrieved correctly and it appears to parse properly but nothing is showing up for my TypeAhead.
Any idea on how to verify exactly where the breakdown is occurring or does anyone see direct fault in my code?
Problem was in the ajax call-
$.ajax({
url: '#Url.Action("MakePartsArray")',
dataType: "json",
type: "POST",
data: {query: query},
success: function (data) {
$.each(data.matches, function (i, part) {
var composedInfo = part.description + ' (' + part.itemNumber + ')';
map[composedInfo] = part;
parts.push(composedInfo);
});
process(parts);
}
});
and in the controller on the return type
return new JsonResult
{
ContentType = "application/json",
Data = new { query, total = allItems.Count(), suggestions = allItems.Select(p => p.itemNumber).ToArray(), matches = allItems },
JsonRequestBehavior = JsonRequestBehavior.AllowGet
};
