Using a ColdFusion function to return query results and was working fine.  Was required to change how I returned the data to SerializeJSON(). But when doing this, nothing returns. Not sure what the issue is unless it has to do with script sources.
I minimized the code to hopefully make it easier to follow. Test.cfm displays the results. TestJS is the JavaScript to call and return the data from Test.cfc file. The last bit of code is what I had that was working. Any ideas? CFDump will return results as well.

Can any javascript.jQuery expert determine why in most browsers the select menus are initially empty instead of showing the default value? I got this off GitHub.

I am updating records using sequelize. I am testing the backend with postman.  The code seems to work as there is no error however when testing it in postman, no rows are affected (updated). I have used both put and patch methods, however, I received the same results. Perhaps, there is an error in the code that I am missing.

Here is the code:

router.put('/editstation/:id', (req, res) => {

             let newStation = req.body.station;
             let newAddress = req.body.address;
             let newMonthlycstoresales = req.body.monthlycstoresales;
             let newOperator = req.body.operator;
             let newTopsku = req.body.topsku;

   let values = {Station: newStation, Address: newAddress, monthlycstoresales: newMonthlycstoresales, Operator: newOperator, topsku:newTopsku};

   let selector = {
       where: {id: req.params.id}
   Store.update(values, selector)
           "message": updatedPost
   .catch(err => {
           "message": err


Here is the json test in postman

I have made my <blockquotes> draggable and I would like to drop them elsewhere in the text - usually inside a <p>.

How do I tell jQuery to insert the <blockquote>  inside a DOM; that is: create/insert a new node where the blockquote was dropped?

I am using this jQuery inside CKEDITOR. If I use appendTo() it creates/adds a new element to the editor's textbox.

Surely, there must a way to do this? I have seen  many examples where the objects are moved around the screen / pictures - but hardly any with text.

Can anyone please assist with this?
I am unable to edit the entries in the bootstrap modal box due to the shadowed backdrop. The cursor is disabled at this point and the screen freezes when the modal box is opened. This only occurs on the first page or a unknown page height of the html page. I would like to enable the ability to edit the values or remove the backdrop altogether if it will solve the problem.

Please see the code below:

I don't understand what the "function" is that useState allegedly passes back. When I look at this:

const [count, setCount] = React.useState(0);

Open in new window

its a little difficult to understand that useState is passing back a function, in addition to the initial value, because I only see one parameter, in this case: 0. So setCount seems to be getting nothing from the call to useState, meaning: it doesn't appear to be getting assigned anything, least of all other function. Can someone explain what's going on here in a different way? If I can state my question another way: What exactly is setCount getting? "count", in the line of code above seems to be getting the value of 0, but what does setCount get? I do understand that later on in the functional component, as all of the examples have shown, one can use setCount to perform some function on the state variable ("count" in this case), but, based on all of the language that I've read about what useState does, it would seem that there should be another parameter passed in with it. Something like:

const [count, setCount] = React.useState(0, thePassedFuntion);

I'm currently working on a custom WordPress site that has a sticky menu enabled, meaning that when you scroll about 100px or so down the page, the menu then remains fixed to the top of the browser.  You can see it in action here:


Although I'm satisfied with the way the sticky menu is working, I would also like to reveal a small company logo in the upper lefthand corner, about 50px from the left edge, and about 25px from the top.  The logo should only be revealed only after the user has scrolled about 180px or so down the page, and should otherwise always be hidden.

Could anyone here help me achieve this?  The WordPress theme is loading the jQuery library, so I'm open to solutions that utilize it, along with whatever custom CSS might be needed.

- Yvan

p.s. I would prefer to implement this as something custom, rather than having to experiment with different WordPress plugins, as I have already tried a variety of different plugins (unsuccessfully).
I am new to sequelize and I created a middleware called "db.js" with a connection to a mysql table called "users". Everytime, I attempt to run the app.js, I am getting this error: "TypeError: app.use() requires a middleware function".

However, I have a middleware function. See the code below: Am I missing something? I have the module.exports object at the end.

Should I have initialize sequelize?

I have a webpage with a Coldfusion / HTML form that is similar to a spreadsheet.  Users can add lines to the form via Javascript or re-sort it with the jquery sortable plugin.  Lately some users have made this form very big and then failed to hit the big save button at the bottom of the page.  They want me to make it automatically save like excel.

Is there a way to have it silently submit the form in the background occasionally?  Would it be better to try and send one field at a time to update when a field loses focus?  I have a lot of small features I have added to it over the years, so I would rather not throw out the whole thing, but maybe that's what I need to do.
I am trying to have a popup with a a nice alert message on my webpage, graying out the background and "OK" button has to be clicked. The page cannot be used until OK, or whatever button is clicked.

Does anyone have a working script for this? I'm assuming it is both CSS and js/jquery.

Thanks much and appreciate it!

Need a jQuery solution to the following:

Imagine a circle with a picture on it. Outside of the circle, and surrounding it, are more, smaller circles (let's say 5). The middle circle is a picture of Bob.  The smaller circles are information about Bob. When the user hovers over one of the smaller circles, an infobox (elsewhere) displays information for that circle.

Any help here would be greatly appreciated.

Hello Experts,

I have an unknown items (received via php and mysql).
Every ".objekt-item" container needs to get wrapped by an ".objects-row" container.
Depending on the screen size; 1 ".objekt-item" per ".objects-row" container or 2 where the max are 3.
The code below works fine yet, while looking on the code via the console I have duplicated ".objects-row" containers with empty content.
I also need to unwrap the ".objekt-item" and remove it (only the wrapper) while resizing the page.
Any help to tune the script would be appreciated !

(function($) {
	var windowLoaded = false;	
	$(window).on('load resize', function() {
	function wrap(elements, wrap, size) {
		var x, i = 0, c = -1, l = elements.length, n = [];
		for(i; i < l; i++) {
			(x = i % size) ? n[c][x] = elements[i] : n[++c] = [elements[i]];
		l = n.length;
		for(i = 0; i < l; i++) {
	if ($(window).width() < 800) {		
		wrap($('.objekt-item'), '<div class="objects-row"></div>', 1);
	if ($(window).width() >= 800 < 1100) {
		wrap($('.objekt-item'), '<div class="objects-row"></div>', 2);
	if ($(window).width() >= 1100) {
		wrap($('.objekt-item'), '<div class="objects-row"></div>', 3);
$(window).on('load', function() {
	windowLoaded = true;

       // executing code

On the very top of this page, I am trying to have the four yellow bulleted points show less content on their initial state because it's just too much overwhelming text.

On #1, I have a "view more" link, which does seem to work. The only issue is that I want that "view more" link to disappear when the paragraph is expanded, otherwise it's looks weird in the middle of the paragraph like that. Then once it's collapsed again, the text can come back.  

I have a document ready function at the bottom of the page. What more do I need to add to make it behave the way I want?

I have a list of jobs on a page, you can click through on an individual list item to a printer friendly page and print the page at the moment, what i would like to be able to do is have a check box next to each list item to be able to select the list items to be printed and create a cue to be processed in the background and sent to the printer, i dont want the page to hang while it processes the request...

Site is written in ASP Classic
I need to be able to print off worksheets from my web pages, but i dont want the page titles and urls to be printed at top and bottom of the page, is there a way to stop this information being printed

the site is built in ASP classic,  will  use jquery/javascript to accomplish this if that is the way to go

Alternatively can you send options to the print preview screen to remove these from the page instead of having to change them in the print preview screen
I'm doing an ajax call to a ColdFusion function to return a query. It should return a single record with three columns for an event's title, description, and date. I want to place each of those three pieces in their corresponding divs. Everything is working fine but I can't figure out how to access the results, and the options I've Googled up have failed me. How do I get the JSON equivalent of CF's queryName.columnName? Thanks!

The jQuery I'm using is as follows:
		 var id = this.id;
		 var splitid = id.split('_');
		 var eventID = splitid[1];
		 // AJAX request
			type: "POST",
			url: "/cfc/calendar.cfc?method=getEventAjax",
		  dataType: "json",
			data: {
			 returnFormat: "json",
			 eventID: eventID
			success: function(response){ 
				// Add response in Modal body
				$('#eventTitle').html(what goes here for the title?);
				$('#eventDescription').html(what goes here for the description?);
				$('#eventDate').html(what goes here for the date, and what about formatting?);
				// Display Modal
			error: function (response) {
        $("#modal-body").html("This event could not be loaded.");

I want a list of checkbox items. As the user selects the items, I want them to appear in a list on the right.

If possible, I want each item to have a point value and as they select them, it totals the points selected.

I don't want to use a database or anything fancy.

Using amchart, version 4, I would like to create various charts types (Line & Area, Pie & Donut, Column & Bar, XY & Bubble).

I wish to use an external datasource from a mysql database using node.js. How can I reference the columns of the data to be used from the database?  

I understand from the documentation on www.amcharts.com, that you can either put the raw data(such as an array) within the javascript code or you can use a "csv" file or a "json" file but I do not see any information on how to use information from a url from the server.  

See below an example using a csv file.

    "url": "/data/myData.php",
    "parser": {
