Sorry, there is nothing more I can do. When I run those few lines of code I get the correct answer. But I cannot reproduce your problem since i do not have all the code.

So, I am experimenting with recordRTC. I can create the recording and produce a webm file.
Now I need to upload it from the client to the server so I can convert it to mp4.
Any ideas how i can achieve this efficiently?
Thanks,
Ray

I'm building an application with node.js, and I'm facing a problem connecting javascript or jquery with my node backend APIs. as an example: I can not do import to my controller APIs folder for the javascript or ajax, I tried to do ( type='modle') in config but it make it worse, show me errors for all my (require), so if there's an easy way to connect my scripts with my APIs I will be glad to you guys. even Axios (import axios from 'axios';) did not work with me. and I'm using pug template.

Hi, I have this line of javascript code inserted in a function...
..
<b>select.options.add(new Option("Standard Floor Base (Base a pavimento Standard)", "SFB"));</b>
..
With this other line of code I access the properties of the "select"....
..
<b>select.classList.add("selectBlock");</b>
..
In the .css...
..
<b>.selectBlock{
font-size: 12px;
width: 290px;
height: 20px;
margin-left: 15px;
}</b>
..
Through a file . css recall the "class" "selectBlock" and change some properties inserted in the "select"...
<b>"Standard Floor Base (Base a pavimento Standard)"</b>
..
I wish I could change only the first part of the text inserted in the "select", exactly this text..
<b>"Standard Floor Base"</b>
..
Is it possible ?... thanks for the help...

let elements;
let element_text;
let artistname = 'Hans Zimmer';
let spotify_window = window.open('https://open.spotify.com/search/Hans%20Zimmer');
setTimeout(function () {
}, 5000);
elements = spotify_window.document.querySelectorAll('._45331a50e3963ecc26575a06f1fd5292-scss._3957b7dd066dbbba6a311b40a427c59f-scss:not(.good-one)');
alert(elements[0]);
for (let element of elements) {
element_text = element.innerText;
if (element_text == artistname) {
element.click();
break;
}
element.classList.add('good-one');
}
the class name isn't wrong
https://ibb.co/sFTFt81
Also, if I execute the following code in that tab's console, it worked
let elements;
let element_text;
let artistname = 'Hans Zimmer';
elements = document.querySelectorAll('._45331a50e3963ecc26575a06f1fd5292-scss._3957b7dd066dbbba6a311b40a427c59f-scss:not(.good-one)');
alert(elements[0]);
for (let element of elements) {
element_text = element.innerText;
if (element_text == artistname) {
element.click();
break;
}
element.classList.add('good-one');
}
see:

then it clicked and jumped to the page

Javascript in a page from one domain is not allowed to access or modify documents from another domain.
This is a security restriction. Imagine what would happen if code on evilbadguys.com was able to click the "Transfer all my money to the bad guys" button on the yourbank.com site!
There is no way around this, unless you want to try to convince all of your users to severely compromise the security of their browsers.

Hello everyone, given that I’ve just started reading HTML code and Javascript language, someone can help me solve this little problem, I’ll give you a generic example, imagine you have a table containing three "checkboxes" A, B and C, the same table contains three "radiobutton" position 1, position 2 and position 3,so for checkbox A we have the possibility to assign only one of the three radiobutton position 1 or 2 or 3 and so also for the other two checkboxes B and C, correspond only one of the three radiobutton, for example, we have selected the checkbox A and the radiobutton corresponding to position 2, I must ensure that, by selecting checkbox B or C, it is no longer possible to select the radiobutton at position 2, because it has already been chosen for checkbox A and so for any other combinations between these specific checkbox and radiobutton, I hope to have explained myself, some help or suggestion thank you.
|
|
|
|
|
I am not sure I understand the question but you can only select one radiobutton in a group. So having selected checkbox A and radiobutton 2, if you then select checkbox B and radiobutton 1, then when the Javascript code processes the checkbox settings, it will only 'see' radiobutton 1 as set.
|
|
|
|
|
Exactly, the javascript function, allows checkbox B to be able to select the radiobattun 1 or 3, since the radiobutton 2 has already been selected in the line of checkbox A, you must also see what happens to the line of checkbox C, if radiobutton 1 or 2 or 3 have been selected, it is the creation of this function that is the problem...
|
|
|
|
|
I still do not fully understand what you are trying to do. You can only have one radiobutton set at any time. As soon as you change it then the previous setting is lost.
|
|
|
|
|
I'm guessing there are three sets of radiobuttons, one for each checkbox.

Probably not the nicest UX, but you can disable the radiobuttons based on the previous element selection.
For example, given the markup:
<ul>
<li>
<label><input type="checkbox" name="a"> A</label>
<ul>
<li><label><input type="radio" name="opta" value="1"> Position 1</label></li>
<li><label><input type="radio" name="opta" value="2"> Position 2</label></li>
<li><label><input type="radio" name="opta" value="3"> Position 3</label></li>
</ul>
</li>
<li>
<label><input type="checkbox" name="b"> B</label>
<ul>
<li><label><input type="radio" name="optb" value="1"> Position 1</label></li>
<li><label><input type="radio" name="optb" value="2"> Position 2</label></li>
<li><label><input type="radio" name="optb" value="3"> Position 3</label></li>
</ul>
</li>
<li>
<label><input type="checkbox" name="a"> C</label>
<ul>
<li><label><input type="radio" name="optc" value="1"> Position 1</label></li>
<li><label><input type="radio" name="optc" value="2"> Position 2</label></li>
<li><label><input type="radio" name="optc" value="3"> Position 3</label></li>
</ul>
</li>
</ul> then the following Javascript will dynamically enable or disable the radiobuttons as you select different options:
let updateOptions = () => document.querySelectorAll("input[type='checkbox']").forEach(chk => {
let li = chk.closest("li");
li.querySelectorAll("input[type='radio']").forEach(rbn => {
if (!chk.checked){
rbn.disabled = true;
rbn.checked = false;
return;
}
let value = rbn.value;
let prevLi = li.previousElementSibling;
while (prevLi !== null){
var prevRbn = prevLi.querySelector(`input[type='radio'][value='${value}']`);
if (prevRbn?.checked){
rbn.disabled = true;
rbn.checked = false;
return;
}
prevLi = prevLi.previousElementSibling;
}
rbn.disabled = false;
});
});
document.querySelectorAll("input[type='checkbox'], input[type='radio']").forEach(el => el.addEventListener("click", updateOptions));
updateOptions(); Demo[^]

I want to make this project: https://codepen.io/samuelbeard/pen/Dsdie, to where when you upgrade, it will increment to 0.01 Click Per Second Automatically, instead of 1 click per second. I am pretty sure this has to do with a function, but I am a beginner and cant find anything to change it, and dont have the knowledge. Is there a variable I have to change, or what?

I'm new to JS, hope this will for help. I'll give you a feedback, after completing your Tutorial.

Sorry, I cannot take the credit for W3Schools.
|
|
|
|

I guess I'll leave the feedback there.

I never wanted the code for the project. Sorry if I was not specific! Accept my sincere apologies for using the wrong forum as well.

1) We're happy to help if you have specific questions about code you have written, but nobody here is going to do your assignment for you.
2) Nobody is going to visit a link on a dodgy website to see the details of your question. Either post the question details here, or don't post at all.
3) It's not "urgent" to anyone but you. All you're doing by adding "urgent" to your subject line is telling us that you can't manage your own time.
4) You have posted this in the Javascript forum. Despite the similar names, Java and JavaScript are two completely different languages.

Chrome wont autoplay a video embedded with javascript, unless its muted. But i cant figure out how to use code to unmute it.
problem is that i am repurposing code [listed below, and in link]. it embeds video in an iframe. there is no variable to access the mute of that i can see. thus the vid variable below doesn work.
The whole code is at https://codepen.io/richardengle/pen/poNjvpY
Line 33 of the area of JS code is where i would change. you can see the vid muted/unmuted part, but it wont unmute the video. Any advice is welcomed
----- part of code----
$('button#play20s').click( function() {
$('body').removeClass().addClass('on playing20s');
$("#knob").trigger('play');
$("#tune").trigger('play');
$('.video-embed').remove();
$('body').append('<iframe id="decade-20" class="video-embed" width="560" height="315" src="https://www.youtube.com/embed/gTevoUhDeoM?&theme=dark&autoplay=1&keyboard=1&autohide=2&start=10&mute=1" frameborder="0" allowfullscreen ></iframe>');
var vid = document.getElementById("decade-20");
vid.muted =false;
//https://www.youtube.com/embed/gTevoUhDe

You can't. That's the whole point - the video can only be un-muted if the user interacts with it.
If there was any way to circumvent that, then every dodgy site in the world would have auto-playing un-muted videos shouting their scam messages as soon as you loaded the page.

I am working on an Ember application, I have a following JavaScript Code written to limit the entry of digits after decimal, this function is called in Key-Down event. Its working but what it is doing it, it allowing 3 digits after decimal but when I am posting its value on the Service, that is taking correctly 2 digits after decimal but what it is showing in the Textbox is 3 digits after decimal.
And another request if possible is, can I do the same without using id attribute on the Textbox.
Any help please, thanks in advance.
allowOnly2Decimals: function (e1, event) {
var boxId = '#' + event.path[0].id;
if ((event.keyCode == 190) || (event.keyCode == 110)) {
this.decimalPressed = true;
}
if (this.decimalPressed) {
var t = e1.toString().split('.');
if (t[1] != null) {
if (t[1].length == 2) {
this.limitDecimal = e1;
$(boxId).val(e1);
}
if (t[1].length >= 2) {
e1 = this.limitDecimal;
$(boxId).val(e1);
return false;
}
}
}
}

No need to use Javascript:
<input type="number" scale="0.01" /> Or:
<input type="text" pattern="^\d+(\.\d{0,2})?$" />
