  1. This should be so simple... I am using a canvas variable here (i) without any problems: for (i = 1; i < 10; i++) { c = document.getElementById("canvas" + i.toString()); context = c.getContext("2d"); context.drawImage(image,0,0,c.width,c.height); } But I cannot seem to get it right here: function clicked(thumbNumber) { //drawImage() in canvas5 using canvas1 as the source var canvasNumber = "canvas" + thumbNumber.toString(); canvas5.getContext('2d').drawImage(canvasNumber, 0, 0); }

  3. Ok, I might be in the wrong place, pardon if I am. It's been awhile since I coded anything let alone Java and I need a real quick refresher. Quick outline: Online Monthly newsletter. I want user to select Year and month, and display type then hit submit button which will then open a new window with the corresponding Newsletter in the corresponding format. These are all 1 page html documents. Listbox1 has the months, listbox2 has the years. Button1, Button2, Button3 are Show as PDF, Show as Word, Show in Browser respectively. Filenames are Month Year Newsletter.EXTension

  5. BACKGROUND: I found the appended script on the net and am inclined to believe that it could prove very useful. i would like to share it with you in the hope that those better versed in Javascript than I might provide insight into its proper use. The annotation enclosed as follows /* ... */ is mine and may be inaccurate. /* * Brief Description: A script for tracking in real time. * Date: 20 February 2018 (downloaded from internet) * Source: Neezer at Stackoverflow * Link: https://stackoverflow.com/users/32154/neezer */ /*********************************************************
  6. I've built a static site with over 40,000 pages using Jekyll. I am trying to implement a live search into it without a database. I tried the w3schools live search example with a xml file I created from my site. It is very slow. Does anyone know of a faster way to parse xml files or am I wasting time. I enabled gzip compression on the entire site also, What would be the fastest way to search a lot of records and return a result? Thanks in advance.
  7. UNDERSTANDING THE PROBLEM: Probably the best way to understand the problem that the following piece of code produces is to observe the problem in action. Please do the following: Open to the Grammar Captive podcast_hostpage.php. Look for the following path in the navigation bar on your left: Podcast Archives/Concept/Podcast Index ... Click on the words Podcast Index ... Run your mouse over the list stopping at various places within the list until the following effect is produced. An unending back and forth opening and closing of the <li> elements of a part
  8. QUESTION: What is the best way to trigger a script stored in a fetched file. BACKGROUND: I send a query string via an HTTPRequest to a file that upon confirmation loads a script containing AJAX calls. I want to know the best way to get the AJAX calls to run when the file in which they are contained is loaded into the file that contains the HTTPRequest. PROPOSAL: Someone on the internet suggested that the code be placed in an anonymous function that is triggered with the ( ) operator. //data.js function() { code to trigger } $.getScript('data.js', function(data) { (); }
  9. SET-UP: Please find below three items including; one, the relevant form elements of a much larger form; two, the Javascript that determine what data will be sent to a PHP processing page via a $_POST variable, and three, The actual implementation of the code. The question follows the presentation of the code. The HTML <div id='language_options' style='clear:both;'> <label for='nl_tongue'>Native Tongue:<span class="formlabel">*</span></label> <span class="rightfloat"> <select id="nl_tongue" name="language" style="width:150px;"> <op
  10. im editting a javascript of an audio player for HTML5, and it doesnt have any shuffle option, i wanted to add it manually and be activated by default. In the code i show, i show the functions that plays o passes to the next song, so you can see the function names im using. im actually studying web design (basic level) and i havent seen javascript yet, so i understand so basic how it works, so i can edit a few things from a copied source. I obviously googled what im asking here, but i couldnt find any answer that i can understand, or make it work, just found some stuff that make things har
  11. BACKGROUND: Using AJAX I have successfully filled a <div> element with HTML that contains a <form> element whose action attribute points to a $_SERVER_REQUEST superglobal in the same filled <div> element. I have also set the target attribute of the <form> element to _self. Unfortunately, when the <input type='submit'> form control is clicked the entire page is replaced. I want only that the contents of the <div> element is replaced. DILEMMA: I want to suppress this replacement behavior, but still process the form data with the PHP contained within
  12. Hi there, Sorry but my JS-Knowledge is very bad. I tried to implement multiple slideshows wthin one website. I used this tutorial. But I'm not able to create more than two slideshows without bugs. I tried to adjust the JS code but wasn't successful. At least I have to implement 4 slideshows. My Code: <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <style> * {box-sizing: border-box} body {font-family: Verdana, sans-serif; margin:0} .mySlides1, .mySlides2 {display: none} img {vertical-align: middle;}
  13. Hi, I would like to know if it's possible to use javascript (specially on Anki; if you know what it is) to format a text line into a html table. Basically, what I want is to copy the definition of an online dictionary (japanese in this case): 長/long, leader/ながい、おさ/チョウ And have the javascript read the first "/", select what's behind it, put in a <th>, select what's between first and second /, put in a <td>, and so forth. I have the CSS set up already. All of this in real time, like, when the software tries to show the line above, the JS will format it to show the styl
  14. I am trying to adapt some code I found online and I don't understand one (actually more) of the lines of code. The code is from a function to generate dropdown lists that depend on previous dropdown lists. The line says "echo "addOption(document.drop_list.Category, '$nt1[cat_id]', '$nt1[category]');";" What does the $nt1 mean and why are there two different values for it? Can someone explain this to me in novice language? I can't find any reference to addOption in the Javascript reference. I'm trying to substitute my table fields into the code, but can't figure ou
  15. I have a process that runs every 30 seconds and i want my script to check if it is finished. this way my user doesn't have to wait an arbitrary 30 seconds if the request is submitted closer to the 30 second mark (5 seconds to process instead of the max 30). I tried a while loop and sending $.post within it but from my console logging it doesn't appear to process the while loop as intended var iii = 1; while(iii < 30){ console.log("Checking rcon queue for " + characterID + " (" + iii + ")"); //Code to wait 1 second before continuing. var start = new Date().getTime(); var

  17. I am trying to build a basic tool to display someones congress representative via zipcode. The API that I am trying to use is offered for free via: https://whoismyrepresentative.com The link to get the data via zipcode is: https://whoismyrepresentative.com/getall_mems.php?zip=31023 It can also be formatted for json like this: https://whoismyrepresentative.com/getall_mems.php?zip=31023&output=json I have read a ton of articles on how to display this data but the trouble I am having is getting the data to show up at all. My first attempt was based off w3schools exam
  18. BACKGROUND: Sometimes I believe that I will never launch my project. The reason for this doubt is clear. Each time that I believe that I have got everything right, I make a small change that i am told will make everything better, and I finish by having to redo much of what I have already done simply to make it work as it did before with the new feature. What keeps me going on the other hand is that I have always somehow been able to overcome each of these sorts of major hurdles. No wonder it has taken me 14 months just to be able to get where I have gotten. DILEMMA: In order to obse
  19. Hi, can anyone help me to understand where to put the "while" function in the code so i can display more than one row from the table please. This is the code i use: <?php $data_sheet = false; $datasheet_query = $db->Execute("SELECT TECHLINK_ID, TECHLINK_INCODE, TECHLINK_URLID, TECHLINK_products_id, TECH_URL, TECH_TITLE FROM FTECHLINK LEFT JOIN FTECHSHEET_URL ON TECH_ID = TECHLINK_URLID WHERE TECHLINK_products_id = ".(int)$_GET['products_id'].""); if (!$datasheet_query->EOF){ $data_sheet = true; $pdf_title = $datasheet_query->fields['TEC
  20. I have some W3.CSS accordions on a webpage based on this tutorial. They work fine, but I'd like to change the button text too (not just show/hide the div) When shown, I'd like the button to show "Click for details". When hidden, I'd like the button to show "Hide details". Thanks in advance for any assistance/advice you can give me.
  21. GREETING: I hope that everyone who celebrated the American holiday of Thanksgiving this past week spent a wonderful holiday full of cheer, good food and drink, and restored family ties and friendships. My celebration was short, alone, but very well spent. And, in the quiet of the office, abandoned by nearly everyone for the holiday break, I was able to finish nearly three weeks of study, investigation, and experimentation with the grammar of the MySQL database. You may discover the results by clicking on any direct reference to a specific podcast on the Grammar Captive Weekly Podcast webpa
  22. Hello, I've been adapting the code from the Slideshow how-to (https://www.w3schools.com/howto/howto_js_slideshow.asp) for my site. However, I would like for the previous arrow to be hidden in the first image and for the next arrow to be hidden in the last image. In other words, no looping. This is for the manual slideshow. I'm not a coding expert, I adapt already existing code, so I'm not sure where to begin. Thank you! The JavaScript from the how-to page is: var slideIndex = 1;showSlides(slideIndex);function plusSlides(n) { showSlides(slideIndex += n);}functio

  24. Hello, this is my first post on the forums after learning HTML and JavaScript for the past 2 weeks. I have a suggestion to make for the JavaScript Functions tutorial, specifically learning how to call a function. The tutorial is very good overall and I am enjoying learning about HTML & JavaScript. As this is my first exposure to coding, my suggestion may be out of place or unusual that I did not know this particular information. However, the JavaScript tutorial never to my knowledge taught me how to call a function the way Exercise 1 at the bottom of the Function tutorial (https://www.w3sc
