  4. Hello everyone, i have created a html form and a button. Javascript reacts to the button click sends the html values to functions.php and there i have a function to insert into the wordpress database. Every field is working and is being inserted into the database but i have some problems to upload and save a image file with these steps. Iam not using a html form i wanted to go the javascript way. Is there any option/solution to insert an image file as blob into mysql using php without form submit just via javascript ajax ? Thanks and best regards,
  5. I finished studying html, and i started CSS but its same as html. should i skip css and just go to JS? i have a background in c (arduino and raspberry pi ), am not interested in the whole front-end code (its like making a power-point presentation more than coding). when am going through css its like a am going through html yet again. i could finish it in a week probably (since i finished studying html and since it seems like css is the style sheet of html). am just feeling like am wasting my time. I have this bad habit, if i start reading something, i don't feel completed if i don't go
  6. I have a use case where my content editable div accepts only string inside it but it shows the html elements as they are supposed to be shown on website but as per the configurations mentioned in package. They have mentioned the attributes but not click events. Now, if I have string as `some text here <button onclick=someFunction()>button</button>`. Here someFunction is directly being called without triggering button because I think it is in string. How can I call `someFunction()` only when button is clicked.

  8. This code gives an error that x[m] is undefined when it calls show(i) but it works fine if I call like show(0). What happens? I already declare x and m then why it gives an error?

  9. MOTIVATION: It is sometimes said that time heals all. With this in mind I am hoping that the W3Schools community has advanced since the last time that I communicated and has found a solution to the following problem. BACKGROUND: Recently I created a new webpage that can be found at www.publiustwo.com/ali. If you open this page in an iPhone with a vary narrow viewport such as my own, you will observe that filling in any of the form items that require text input, and in several cases even those that do not, causes the width of the document to increase beyond the size of the available v

    Animated Modal Box

    I create a modal box that when the user clicks on the button the modal will appear with animation. When the user clicks on the close button ( located on the right side of the header area ) or anywhere of the screen except modal box it will disappear without animation. I want that the modal will disappear/hide with animation. I create two CSS animation. One is animatetop which I already used when modal will open and another is animatedown which I want to use when modal will disappear. But, I can't understand how to do that? See the code on JSFiddle <html> <

  12. I have an intersection observer for one animation, but i want to use window.requestIdleCallback() Where I should add the code window.requestIdleCallback(callback_1)? my script: if (document.querySelector('#weddings')) { let observer_1; let Element_1; let prevRatio = 0.0; let options = { root: null, rootMargin: "0px", threshold: buildThresholdList() }; // Set things up Element_1 = document.querySelector("#img-1"); initObserver(); ////////////////////////////////////////////////////////////////////////////// function initObserver() { observer_1
  13. I am pretty new to javascript and node.js. I am wanting to display some text using document.getElementById('txt').innerHTML= "some text" followed by a node module : var spawn = require('child_process').spawnSync; child = spawn('ffmpeg',['-y -i ',some_file , result_file ], { shell: true }); (which takes some time) and then document.getElementById('txt').innerHTML= "some other text"; However it only disp[ays the second lot of text after the external program has finished. I had assumed that as I am using the synchronous version of spawn that the fir
  14. I followed the following tutorial and I was finally able to add a slide in menu on my WordPress site. However, I noticed that the body scrolls when moving up and down on my mobile phone. Can someone explain to me how I can disable body scroll when the menu is opened? Many thanks in advance!

  21. Hello All, I have a question in regards to an idea I have and was curious as to which of the JavaScript tutorials would be a good place to start. What I had in mind was an image that would swap through a series of pictures, say for example of 10. I would like these images to swap over over in one of four directions randomly, image 2 would say for example slide image 1 from the top, image 3 would slide from the left, etc. Which of the JavaScript Tutorials here would be a good place to start for this idea? I am aware of the setInterval() command to switch between images after x amount of mi
  22. Hello! I'm looking for some help with my Javascript code. I have a services page with 5 tabs. I used w3schools to obtain and tweak this code as needed. However, I need to link to a specific tab from my home page and I'm having trouble editing the Javascript to make this possible. Here's what I have thus far: Services Page HTML: <div class="col"> <button class="tablinks" onclick="openCity(event, 'nonclinical')"><div class="tab-wrap-blue"><div class="nonclinical" style="height: 90px;"> </div><div class="tablink-head stories mobile-no"><h4>N
  23. BACKGROUND: I recently install nodejs and npm and downloaded a library call xregexp.js Then, I discovered what I did not know. The applications nodejs (node) and npm are primarily designed for server-side Javascript. Now, I am confused. In PHP one can simply include or require PHP from another document file and employ it wherever you like that PHP can be used. When I try to do something similar with xregexp.js I inevitably fail and am told that the script cannot be found. Now, I have node and npm installed above my domain folders so that it can be used with all of my domains. Simpl
