Textbox to values goes into round number

I bought a PHP script (https://codecanyon.net/item/easy-inventory) for distributor agency. but when I tried to add quantity like 2.55, it turned to 255. First one is textbox code and second one is JS. when I remove onblur ="order(this); "I can enter 2.55 value into textbox but the calculation is not processing. check image:
<td class="vertical-td">
<input type="number" name="qty" style="width: 90px" value="<?php echo $item['qty'] ?>" onblur ="order(this);" id="<?php echo 'qty'.$item['rowid'] ?>" class="form-control">
</td>
Here is JS code

var xmlhttp = false;
try {
xmlhttp = new XMLHttpRequest();

catch (e) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

}
catch (e1) {
xmlhttp = false;
}
}
}
return xmlhttp;

How do I call a vendor library from my main.js?

I have a basic electron app where I am trying to use vendor supplied js library. The example they supplied provides a static html page which includes their custom library and an example js file. This is the html
<HTML>
<HEAD>
<TITLE> MWD Library </TITLE>
</HEAD>
<BODY>
<h2>MWD Library Example</h2>
<input id="authAndConnect" type="button" value="authenticate and connect to stream" onclick="authenticateAndConnectToStream()" /></br></br>
<input id="clickMe" type="button" value="place position" onclick="placePosition()" /></br></br>
<input id="unsubscribeMe" type="button" value="unsubscribe" onclick="unsubscribe()" />
<input id="streamError" type="button" value="reconn to stream" onclick="reconnectToStream()" />
<input id="historicalData" type="button" value="historical data for GOLD" onclick="getHistoricalData()" />
<input id="goldExpiries" type="button" value="expiries for GOLD" onclick="getCurrentGoldExpiries()" /></br></br>
<input id="userTrades" type="button" value="active&completed trades" onclick="getUserTrades()" />
</BODY>
<SCRIPT SRC="jquery.ajax.js"></SCRIPT>
<SCRIPT SRC="mwdlib.js"></SCRIPT>
<SCRIPT SRC="app.js"></SCRIPT>
</HTML>
In the example above the button click calls authenticateAndConnectToStream in their example apps.js
//DEMO
//provide API key
MWDLibrary.config("dwR4jXn9ng9U2TbaPG2TzP1FTMqWMOuSrCWSK5vRIW7N9hefYEapvkXuYfVhzmdyFypxdayfkUT07HltIs4pwT0FIqEJ6PyzUz0mIqGj1GtmAlyeuVmSC5IcjO4gz14q");
//authenticate on MarketsWorld
var getAuthTokenParams = {email:"rtmarchionne#gmail.com", password:"Pitts4318AEM"};
var authenticateAndConnectToStream = function(){
MWDLibrary.getAuthDetails(getAuthTokenParams, function(authDetails) {
//optional: get older data
var marketsToSubscribeTo = ['GOLD', 'AUDNZD'];
for (var i = 0; i < marketsToSubscribeTo.length; i++){
MWDLibrary.getHistoricalData(marketsToSubscribeTo[i], function(response) {
console.log(response);
}, function(errorMessage) {
console.log(errorMessage);
});
}
//now you can connect to stream
MWDLibrary.connect(marketsToSubscribeTo, function() {
addMarketsListeners();
}, function(errorMessage) {
console.log(errorMessage);
});
}, function(errorMessage) {
console.log(errorMessage);
});
};
I want to call the same methods that start with MWDLibrary. from my main js like MWDLibrary.config("dwR4jXn9")
My main.js:
const electron = require('electron')
var path = require('path');
var countdown = require(path.resolve( __dirname, "./tradescaler.js" ) );
var mwd = require(path.resolve( __dirname, "./mwdlib.js" ) );
const app = electron.app
const BrowserWindow = electron.BrowserWindow
const ipc = electron.ipcMain
let mainWindow
app.on('ready', _ => {
mainWindow = new BrowserWindow({
height: 360,
width: 700,
title: "TradeScaler Beta - Creative Solutions",
//frame: false,
alwaysOnTop: true,
autoHideMenuBar: true,
backgroundColor: "#FF7E47",
})
mainWindow.loadURL('file://' + __dirname + '/tradescaler.html')
mainWindow
//mainWindow.setAlwaysOnTop(true, 'screen');
mainWindow.on('closed', _ => {
mainWindow = null
})
})
ipc.on('countdown-start', _ => {
console.log('caught it!');
MWDLibrary.config();
countdown(count => {
mainWindow.webContents.send('countdown', count)
})
})
In my main.js above I get an error that says MWDLibrary is not defined.
Is it the structure of the library that is the problem? do i have to pass a window or modify the library?

You're missing the .js file extension at the end of mwdlib
And you may need to require it using the full system path, instead of a relative one.
var mwd = require(path.resolve( __dirname, "./mwdlib.js" ) );

How to display alert after AJAX post success.alert?

In my Node application I have used get and post request. Using get just renders the page and using post insert data into MySQL database. Data is inserted properly but after post gets called and alert fade away very quickly.
This is my code from app.js:
app.get('/Associate', routes.Associate);
app.get('/addAssociate',routes.addAssociate);
app.post('/addAssociate',routes.postAssociate);
This is my code from routes.js:
Associate: function(req, res) {
sess = req.session;
var name = req.session.user;
var username = 'SELECT first_name from user_info where email_id=?';
if (sess.user) {
console.log('\n--------------------- Associate ----------------------');
var db = req.app.get('db')();
var id = req.query['id'];
// var newsquery='SELECT * from associate_info';
var assoquery = 'SELECT associate_id,doctor_id,CONCAT(initial," ",first_name," ",middle_name," ",last_name) As Name,qualification,address_line1,city,state,pincode,email_id,contact_no from associate_info ';
var redirect = 'Associate_Listing';
async.parallel({
one: function(callback) {
db.query(assoquery, function(error, rows, fields, next) {
console.log("length-\t", rows.length);
callback(error, rows);
});
},
two: function(callback) {
db.query(username, [name], function(error, rows, fields, next) {
// console.log(rows.length);
console.log(rows);
callback(error, rows);
});
}
},
function(error, results) {
var totalNews = results.one.length;
for (var i = 0; i < results.one.length; i++) {
if (!(results.one[i].views > 0) || results.one[i].views == null)
results.one[i].views = 0;
results.one[i].ids = i + 1;
// if(!(results.one[i].views>0))
// results.one[i].views=0;
}
// console.log("--------",results.one[0].id);
res.render(redirect, {

});
I want to display an alert after data inserted successfully into database.

Just Try the Following to make some delay.
jQuery :
$.ajax({
url:'path-to-process',
type:'POST',
data:{},
success:function(){
// Content to Display on Success.
setTimeout(function () {
// Content to Display on Success with delay.
}, 800);
}
});
Here, the "setTimeout()" will provide some specified time delay for display your content.
Have a Nice Day !

If you are using the plan old JavaScript,you can using the XMLHttpRequest status code to determine whether is success or not

Pubnub getting duplicated message when changing channel

I have a problem with pubnub.
I have friends list and I need to change pubnub channel on clicking them, by switching to another friend, to chat with him.
I have global channel variable, and I am changing it on friend click. The problem is, when I switch to another friend and write a message, the message appears in panel is duplicated.
Here is the code I am using.
base = "/";
pubnub = "";
channel ="";
messageListContent = "ul.chat-messages-block";
function handleMessage(message,$index) {
if ( $index != 'me' ) {
var $index = 'left';
} else {
var $index = 'right';
}
var $imageUrl = "";
if ( message.picture != '' && message.picture != null ) {
$imageUrl = message.picture;
if ( (/^http:\/\//.test( $imageUrl ) ) ) {
$imageUrl = $imageUrl;
} else {
$imageUrl = "uploads/user/"+ $imageUrl;
}
} else {
$imageUrl = 'resources/images/user-male.png';
}
var messageEl = jQuery('<li class="'+$index+' clearfix">'+
'<div class="user-img pull-'+$index+'"> <img src="' + $imageUrl +'" alt="'+message.username+'"> </div>'+
'<div class="chat-body clearfix">'+
'<div class="">'+
'<span class="name">'+message.username+'</span><span class="name"></span><span class="badge"><i class="fa fa-clock-o"></i>'+message.chat_date+'</span></div>'+
'<p>'+ message.message + '</p>'+
' </div>'+
'</li>');
jQuery(messageListContent).append(messageEl);
};
jQuery.getJSON( "/chat/read", function( data ) {
var items = [];
if ( data != null && data != "" ){
pubnub = PUBNUB.init({
publish_key: data.publish_key,
subscribe_key: data.subscribe_key,
});
if ( data.messages.length > 0 ) {
var $my_id = data.current_user;
for( var i = 0; i < data.messages.length; i++ ) {
if ( data.messages[i].user_id == $my_id ) {
$index = "me";
} else {
var $index = "";
}
handleMessage(data.messages[i],$index);
}
}
}
});
jQuery(document).ready(function () {
jQuery('#sendMessageButton').click(function (event) {
var message = jQuery('#messageContent').val();
var friend_id = jQuery('li.activeChannel').attr('data-id');
if ( message != '' ) {
jQuery.ajax({
url: base+"chat/sendChat",
type:'POST',
data:{
friend_id: friend_id,
text:message
},
success:function(data){
var data = JSON.parse(data);
//sounds.play( 'chat' );
pubnub.publish({
channel: channel,
message: {
username: data.messages.username,
message: data.messages.message,
user_id: data.messages.friend_id,
current_user: data.messages.user_id,
picture: data.messages.picture,
type:'message',
chat_date: data.messages.chat_date
}
});
},
error: function(err){
jQuery('.errorText').fadeIn();
}
});
jQuery('#messageContent').val("");
}
});
// Also send a message when the user hits the enter button in the text area.
jQuery('#messageContent').bind('keydown', function (event) {
if((event.keyCode || event.charCode) !== 13) return true;
jQuery('#sendMessageButton').click();
return false;
});
jQuery('ul.chat-users li').click(function(){
var friend_id = jQuery(this).attr('data-id');
jQuery('ul.chat-users li').removeClass('activeChannel');
jQuery(this).addClass('activeChannel');
jQuery.ajax({
url: base+"chat/getUsersChat",
type:'POST',
data:{
friend_id: friend_id
},
success:function(data){
var data = JSON.parse(data);
jQuery('.chat-messages ul').html("");
//id = pubnub.uuid();
//channel = 'oo-chat-' + id+friend_id;
channel = 'oo-chat-' + data.channel;
if ( data.messages.length > 0 ) {
var $my_id = data.current_user;
for( var i = 0; i < data.messages.length; i++ ) {
if ( data.messages[i].user_id == $my_id ) {
$index = "me";
} else {
var $index = "";
}
//messageListContent = "ul.activeChannel"+channel;
//console.log(channel);
handleMessage(data.messages[i],$index);
}
}
pubnub.subscribe({
channel: channel,
message: function(message) {
console.log("Pubnub callback", message);
handleMessage(message,"me");
},
connect: function(message) {
console.log("Pubnub is connected", message);
},
//callback:
});
},
error: function(err){
jQuery('.errorText').fadeIn();
}
});
});
});
And here is how it is looking
Any Idea?
I had even tried to unsubscribe the previous channel on friend click, but no result.
What am I doing wrong?

I solved the problem. The problem was in pubnub.js version, it was 3.4, I switched to 3.7.1 and added the following code
jQuery('ul.chat-users li').click(function(){
var friend_id = jQuery(this).attr('data-id');
jQuery('ul.chat-users li').removeClass('activeChannel');
jQuery(this).addClass('activeChannel');
if ( channel != "" ) {
pubnub.unsubscribe({
channel : channel,
});
}

Function within function want to execute very first function completely

I got a problem.I have multiple callback functions .
Function within function within a loop
I want to execute very first function fully first . Then I want to move further.
Currenlty no function is working fine:

I understand the code is too long. I want to get an idea, I want to execute i=0 first completely, then I want to proceed further.
Any Idea how we can do in Nodejs. Any Help Will be appreicated
Thanks

Try replacing the loop with a recursive code like this..
function recurring_end() {

var callbackForParseArticle = function(err,result){
bookamrk_title= result.bookmark_title;
bookmark_body= result.body;
bookmark_file_name= result.file_name;
preview_image = result.preview_image;
local_image_name = result.local_image_name;
mainPreviewImage = result.mainPreviewImage;
viewImage=result.viewImage;
var mediaExist =result.mediaExist;
if(mediaExist == 1) {
console.log("Entered in Media Exist");
download(preview_image, "images/" + local_image_name, function() {
console.log("Entered in download");
fs.exists("images/" + local_image_name, function(exists) {

Use async.js to manage your code flow
If you have multiple functions, func_1, func_2, func_3, that need to run in sequence, the code is
var async = require('async');
var functionList = [func_1, func_2, func_3];
async.series(functionList, function(err, result){
// results of func_1, func_2 and func_3
});
