i am fairly new to coding and i got this typing script online and then created a button, the button links to a different page that I haven't created yet. The issue i am facing is that i cant get the button to stay in one place while the typing script is running, it moves around, is there a way i can put it in a fixed position maybe by the bottom left of the screen. my code is bellow, Thanks!
var TxtType = function(el, toRotate, period) {
this.toRotate = toRotate;
this.el = el;
this.loopNum = 0;
this.period = parseInt(period, 10) || 2000;
this.txt = '';
this.tick();
this.isDeleting = false;
};
TxtType.prototype.tick = function() {
var i = this.loopNum % this.toRotate.length;
var fullTxt = this.toRotate[i];
if (this.isDeleting) {
this.txt = fullTxt.substring(0, this.txt.length - 1);
} else {
this.txt = fullTxt.substring(0, this.txt.length + 1);
}
this.el.innerHTML = '<span class="wrap">' + this.txt + '</span>';
var that = this;
var delta = 200 - Math.random() * 100;
if (this.isDeleting) {
delta /= 3;
}
if (!this.isDeleting && this.txt === fullTxt) {
delta = this.period;
this.isDeleting = true;
} else if (this.isDeleting && this.txt === '') {
this.isDeleting = false;
this.loopNum++;
delta = 5000;
}
setTimeout(function() {
that.tick();
}, delta);
};

You can just change the position: relative; to position: absolute; of button . Button will get out of flow from document and will appear below the text
Did you try using position:fixed?
https://www.w3schools.com/css/css_positioning.asp
And then manipulate top and left.
Ah, maybe more important, put the button inside div, and style the div.
I have JS code on a webpage that loads questions in from mysql db and displays the text . What happens is that it cuts off words at the end of the line and continues the word on the next line at the start. So all text across the screen starts/ends at the same point.
This seems to be the code where it displays the text.
For example the text will look like at the end of a line 'cont' and then on next line at the start 'inue'.
How do i fix this?

I'm guessing that #question{ word-break: break-all; } is probably the culprit then? –
CB..yes that fixed it:)
I am working on one JavaScript project, where I need to toggle between Dark and Light mode.
The HTML is here.

document.documentElement.style.setProperty('--bs', '9px 9px 23px #0f111a, -9px -9px 20px #1a1b32');
document.getElementById("toggle-img").src = "https://img.icons8.com/ios/2x/moon-man.png"
} else {
console.log(btnToggle.style)
btnToggle.style.justifyContent = "flex-end";

When I click first time on icon but nothing gets changed. But after first click on every click code's running perfectly well.
So please solve this error.
you misinterpret the state, your if(isDark) check the previous state.
i.e. if isDark == true then you should change icon to sun
var btnToggle = document.getElementById("btn-toggle")
var btnToggleIcon = document.getElementById("btn-toggle-icon")
var isDark = true;
btnToggleIcon.addEventListener("click", () => {
if (isDark) {
isDark = false;
//at this point it's not dark
document.getElementById("toggle-img").src = "https://img.icons8.com/fluent-systems-regular/2x/sun.png"
} else {
isDark = true;
//at this point it's dark
document.getElementById("toggle-img").src = "https://img.icons8.com/ios/2x/moon-man.png"
}
})
<div class="btn-toggle" id="btn-toggle">
<div class="btn-toggle-icon" id="btn-toggle-icon">
<img id="toggle-img" src="https://img.icons8.com/ios/2x/moon-man.png" alt="" />
</div>
</div>
Your logic is wrong.
You need to change the variable before the check.
btnToggleIcon.addEventListener("click", () => {
isDark = !isDark;
if (isDark) {
console.log(btnToggle.style)
btnToggle.style.justifyContent = "flex-start";
document.documentElement.style.setProperty('--color1', '#10111f');
document.documentElement.style.setProperty('--bg1', 'linear-gradient(145deg, #111221, #0e0f1c)');
document.documentElement.style.setProperty('--color5', '#f1f1f3');
document.documentElement.style.setProperty('--bs', '9px 9px 23px #0f111a, -9px -9px 20px #1a1b32');
document.getElementById("toggle-img").src = "https://img.icons8.com/ios/2x/moon-man.png"
} else {
console.log(btnToggle.style)
btnToggle.style.justifyContent = "flex-end";
document.documentElement.style.setProperty('--color1', '#f1f1f3');
document.documentElement.style.setProperty('--bg1', '#f1f1f3');
document.documentElement.style.setProperty('--color5', '#10111f');

I'm trying to create a simple metronome using the web audio oscillator, so that no external audio files are needed. I'm creating the sound of the metronome by ramping the volume of the oscillator up and down very quickly (since you can't use start() and stop() more than once), and then repeating that function at a set interval. It ends up sounding like a nice little wood block.
The code below works/sounds great in Chrome, Safari and Opera. But in Firefox, there's a nasty intermittent "click" when the volume ramps up. I've tried changing the attack/release times to get rid of the click, but they have to be really, really long before it consistently disappears. So long, in fact, that the oscillator just sounds like a sustained note.
var audio = new (window.AudioContext || window.webkitAudioContext)();
var tick = audio.createOscillator();
var tickVol = audio.createGain();
tick.type = 'sine';
tick.frequency.value = 1000;
tickVol.gain.value = 0; //setting the volume to 0 before I connect everything
tick.connect(tickVol);
tickVol.connect(audio.destination);
tick.start(0);
var metronome = {
start: function repeat() {
now = audio.currentTime;
//Make sure volume is 0 and that no events are changing it
tickVol.gain.cancelScheduledValues(now);
tickVol.gain.setValueAtTime(0, now);
//Play the osc with a super fast attack and release so it sounds like a click
tickVol.gain.linearRampToValueAtTime(1, now + .001);
tickVol.gain.linearRampToValueAtTime(0, now + .001 + .01);
//Repeat this function every half second
click = setTimeout(repeat, 500);
},
stop: function() {
if(typeof click !== 'undefined') {
clearTimeout(click);
tickVol.gain.value = 0;
}
}
}
$("#start").click(function(){
metronome.start();
});
$("#stop").click(function(){
metronome.stop();
});
Codepen
Is there any way to get FF to sound like the other 3 browsers?
I was getting the exact same problem in latest Opera and found the problem to be the individual sounds 'decimal time length'.
I wrote a morse code translator, and like yours, it's just a series of simple short sounds/beeps created via createOscillator.
With morse code you have a speed count (words per minute) based on a 5 letter long word like codex or paris.
To get 20 or 30 paris' per minute to finish exactly on the minute, I had to use a sound time length of, for example, 0.61. In Opera, this caused the 'end of sound click'. On changing this to 0.6 and the click disappeared across all browsers - except Firefox.
I've tried freq = 0 and gain = 0 between sounds but still get the click at the end in FF and I don't know enough about Web Audio to try anything else.
On another note, I noticed you're using a loop and timeout to get to the next tick. Have you tried an 'Oscillator onended function' instead? I've used it with a simple counter increment and variable length blank sound/note. Go to the very end of my JS if you want to have a look.
**UPDATE - I've been fiddling about with setValueAtTime() and linearRampToValueAtTime() and appeared to have cracked the click problem. Scroll to bottom of script to see example. **

It would be best to get Firefox to fix the issue (if indeed it is a Firefox bug with automations). Having said that, you could probably make all the browsers be consistent by using an AudioBufferSource node that has a precomputed click waveform that you want. Just generate a sine wave, ramp it up and down as you want (manually) and play that back at regular intervals.
Not great, but it should be cross-platform.
AFAIK this issue is not specific to Firefox, although looking at your code, I'm unsure why it doesn't happen in other browsers.
The problem is that the moment you schedule a *rampToValueAtTime to an audible source when that source is not currently interpolating between two ramp points, the "clicking" sound occurrs, possibly due to how the underlying implementation will immediately start taking the new ramp point into consideration, even if it's scheduled to happen the future.
The clicking sound will also be heard if you schedule a new ramp point between two points between which interpolation is occurring.
What I came up with as a workaround solution is either using an alternative approach to gradually changing AudioParam values, setTargetAtTime, or setting the value property of the AudioParam to the first ramp point value. Not setValueAtTime, but assigning to the value property itself, before anything audible happens on the given branch.
setTargetAtTime
You'll be needing neither cancelScheduledValues nor setValueAtTime, just two calls to setTargetAtTime, which is just a setValueAtTime with an exponential interpolation with a specified length.
var metronome = {
start: function repeat() {
now = audio.currentTime;
//Play the osc with a super fast attack and release so it sounds like a click
tickVol.gain.setTargetAtTime(1, now, 0.01);
tickVol.gain.setTargetAtTime(0, now + 0.01, 0.01);
//Repeat this function every half second
click = setTimeout(repeat, 500);
}
}

Update
I found the actual issue.
In my code I am referencing the height of the overlay,
In all browsers except IE7 this is the same as the window size, however in IE7 this is the document size.
So I changed it to reference the window size and it works :).
So my question now is, Why does IE7 do this, and am I correct is assuming IE7 is the foul ball here?
Original
I am creating a modal dialog script (for my own use).
The code works perfectly in.
Google chrome,
Firefox,
IE8+
However in IE7 The positioning is all wrong.
Example
These are the positioning values I get in IE9 vs IE7 (keep in mind that the values are smaller than a normal window as i have the dev tools open.)
IE7
left: 367px;
top: 1409px;
IE9
left: 369.5px;
top: 122.5px;
What do I need to do to fix this?
The CSS
Note that this css has some strange rules such as the body tag for testing purposes only.
Note that I am aware that rgba, box-shadow etc does not work in css3 supportless browsers,
I will fix this when the dialog functions properly.

Try removing this line:
body {
height: 3000px;
}
Didn't affect FF when I tested, and I really don't see a use for it anyways.
It's always best to remove unnecessary code when you're trying to get CSS stuff to work so you can nail down the source of the problem, unless you think that box-shadow might be related to your positioning problem.
