Example
var text = 'ENTER...';
var chars = text.split('');
var enter = document.getElementById("enter")
var i = 0;
setInterval (function(){
if (i < chars.length){
enter.innerHTML += chars[i++];
}else{
i = 0;
enter.innerHTML = "";
}
}, 200);
I'm trying to have this typing "enter" effect and I am wondering how to make it only go once. So it will type out "ENTER..." and then stop.
Example
var text = 'ENTER...';
var enter = document.getElementById("enter")
var i = 0;
(function nextLetter() {
enter.innerHTML = text.substr(0, ++i);
if (i < text.length) {
setTimeout(nextLetter, 200);
}
})();
edit: you either have to use setTimeout (one time "sleep"), or remember return value of setInterval and destroy that timer by clearInterval after you don't need it/want it running.
If you use interval, you have to stop the it with clearInterval. Stop it inside the interval function, which is declared as a variable, in the if-statement:
var text = 'ENTER...';
var enter = document.getElementById("enter")
var i = 0;
var interval = setInterval(function() {
enter.innerHTML += text[i];
i += 1;
if(i === text.length) {
clearInterval(interval);
}
}, 200);
JSFiddle
var text = 'ENTER...';
var chars = text.split('');
var enter = document.getElementById("enter")
var i = 0;
var interval = setInterval (function(){
if(i == chars.length) {
clearInterval(interval);
return;
}
if (i < chars.length){
enter.innerHTML += chars[i++];
}else{
i = 0;
enter.innerHTML = "";
}
}, 200);
<div id="enter"></div>

So, I'm trying to create a random text generator in Javascript using Math.floor and Math.random which I combine with countdown timers using Javascript as well. However, the result after the countdown value has been <= 0 does not appear random text that I have made in the function.
In fact, it appears undefined. How's the solution? The script I created is below.
<button id="btn" style="background-color:red;width:30px;height:30px;"></button>
<script>
var timer = 5;
var id;
function create_random_string(string_length){
var random_string = 'X-';
var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890'
for (var i, i=0; i < string_length; i++){
random_string += characters.charAt(Math.floor(Math.random() * characters.length))
}
}
function starButton() {
this.style.display = 'none';
id = setInterval(function () {
timer--;
if (timer <= 0) {
clearInterval(id);
document.getElementById("script").innerHTML = create_random_string(5);
} else {
document.getElementById("script").innerHTML = timer + " seconds to get Code";
} }, 1000);
};
var clickbtn = document.getElementById("btn");
clickbtn.onclick = starButton;
</script>
<div id="script"></div>
You were not returning anything from your function. If you don't return function value how it will get it! Check this now.
var timer = 5;
var id;
function create_random_string(string_length){
debugger;
var random_string = 'X-';
var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890'
for (var i, i=0; i < string_length; i++){
random_string += characters.charAt(Math.floor(Math.random() * characters.length))
}
return random_string;
}
function starButton() {
this.style.display = 'none';
id = setInterval(function () {
timer--;
if (timer <= 0) {
clearInterval(id);
document.getElementById("script").innerHTML = create_random_string(5);
} else {
document.getElementById("script").innerHTML = timer + " seconds to get Code";
} }, 1000);
};
var clickbtn = document.getElementById("btn");
clickbtn.onclick = starButton;
<button id="btn" style="background-color:red;width:30px;height:30px;"></button>
<div id="script"></div>
How can i apply bullets in this below mentioned code after line break. I mean when i break line, i need next line to start with the bullet. Also please apply css animation on this code. Also apply timing i-e when i run code, i can control after how many milliseconds the typing starts and when typing ends, i can control after how many milliseconds it starts again. Thanks
var typeString = ['I\'m Mr. Frits and I love Pakistan...:)'];
var i = 0;
var count = 0
var selectedText = '';
var text = '';
(function type() {
if (count == typeString.length) {
count = 0;
}
selectedText = typeString[count];
text = selectedText.slice(0, ++i);
document.getElementById('typing').innerHTML = text.fontsize(6);
document.getElementById('typing').style.fontFamily = "monospace";
document.getElementById("typing").style.color = "black";
document.getElementById("typing").style.fontWeight = "normal";
if (text.length === selectedText.length) {
count++;
i = 0;
}
setTimeout(type, 300);
}());
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds) {
break;
}
}
}
<pre id="typing" class="typing"></pre>
Just add \n and the unicode •
var typeString = ['• I\'m Mr. Frits\n• and I love Pakistan...:)'];
var i = 0;
var count = 0
var selectedText = '';
var text = '';
(function type() {
if (count == typeString.length) {
count = 0;
}
selectedText = typeString[count];
text = selectedText.slice(0, ++i);
document.getElementById('typing').innerHTML = text.fontsize(6);
document.getElementById('typing').style.fontFamily = "monospace";
document.getElementById("typing").style.color = "black";
document.getElementById("typing").style.fontWeight = "normal";
if (text.length === selectedText.length) {
count++;
i = 0;
}
setTimeout(type, 300);
}());
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds) {
break;
}
}
}
<pre id="typing" class="typing"></pre>
use • for the bullet character when generating the text variable
text = '• '+ selectedText.slice(0, ++i);
I'm trying to mimic the look of a stock-exchange board, but can't seem to automatically change text without stopping another.
I've tried
var text = ["2.0%", "1.7%", "1.9%", "1.8%", "1.9%"];
var counter = 0;
var elem = document.getElementById("n1");
var inst = setInterval (change, 1000);
function change () {
elem.innerHTML = text[counter];
counter++;
var content = document.getElementById("n1");
if (counter >= text.length) {
counter = 0;
}
}
var text = ["-12.0%", "-13.7%", "-13.9%", "-12.8%", "-13.9%"];
var counter = 0;
var elem = document.getElementById("n2");
var inst = setInterval (change, 1000);
function change () {
elem.innerHTML = text[counter];
counter++;
var content = document.getElementById("n2");
if (counter >= text.length) {
counter = 0;
}
}
To no avail.
You can't have two different functions with the same name. One will override the other.
I created a single function that accomplishes your goals by passing in the target element and the data as arguments.
function change(elem, data) {
let counter = 0;
setInterval(function() {
elem.innerHTML = data[counter];
counter++;
if (counter >= data.length) {
counter = 0;
}
}, 1000);
}
change(document.getElementById("n1"), ["2.0%", "1.7%", "1.9%", "1.8%", "1.9%"]);
change(document.getElementById("n2"), ["12.0%", "2.7%", "3.9%", "4.8%", "5.9%"]);
<div id="n1"></div>
<div id="n2"></div>
So, I have a code here that works perfectly fine when I am viewing it in the active browser tab. But, as soon as I minimize or switch between other tabs of the browser (which is chrome by the way) the code starts giving issues. Here is the code below:
var a = document.getElementById("slidermain");
var b = a.getElementsByTagName("IMG");
var len = b.length;
var noOpac = 0;
var fullOpac = 10;
var imgNumb = 0;
function initFade(count){
imgNumb = imgNumb + count;
if(imgNumb < 0){
imgNumb = len;
}
if(imgNumb > len){
imgNumb = 1;
}
elem = b[imgNumb-1];
startFadeEffect(elem);
}
function startFadeEffect(elem){
var opacSetting = noOpac / 10;
if(noOpac > 10){
opacSetting = 1;
}
elem.style.opacity = opacSetting;
elem.style.display = "block";
noOpac++;
var timer = setTimeout(function() { startFadeEffect(elem); }, 55);
if(opacSetting == 1){
clearTimeout(timer);
elem.style.opacity = 1;
noOpac = 0;
setTimeout(function() { endFadeEffect(elem); }, 2000);
}
}
function endFadeEffect(elem){
var opacSetting = fullOpac / 10;
if(fullOpac < 0){
opacSetting = 0;
}
elem.style.opacity = opacSetting;
fullOpac--;
var timer = setTimeout(function() { endFadeEffect(elem); }, 55);
if(opacSetting == 0){
clearTimeout(timer);
elem.style.opacity = 0;
elem.style.display = "none";
fullOpac = 10;
return false;
}
}
function autoFade(){
var loop = setInterval("initFade(1)", 4000);
}
Please not that I have been looking on this site for the answer, but mostly the ones I have found are JQuery based solutions; however, I am looking for a JavaScript only solution in which I might not have to use the get new date function. Please do not mark my question as duplicate as I have done good research. Thanks!
This is not a problem with your javascript, but with Chrome. Chrome does some weird things with your tabs when they aren't active. Add code to "fix the mess", or account for not the tab being active, to recover after tabbing out and back in.
