How to modify code so it doesn't run on reload? - javascript

This code,
function dec2hex(dec) {
return dec < 10 ? "0" + String(dec) : dec.toString(16);
}
function generateId(len) {
var arr = new Uint8Array((len || 40) / 2);
window.crypto.getRandomValues(arr);
return Array.from(arr, dec2hex).join("");
}
var random = generateId(64);
document.getElementById("password").innerHTML = random;
setInterval(function() {
function dec2hex(dec) {
return dec < 10 ? "0" + String(dec) : dec.toString(16);
}
function generateId(len) {
var arr = new Uint8Array((len || 40) / 2);
window.crypto.getRandomValues(arr);
return Array.from(arr, dec2hex).join("");
}
var random = generateId(64);
document.getElementById("password").innerHTML = random;
}, 5000);
<div id="password"></div>
will generate a random string every 5 seconds. However, it generate a new string when the page is reloaded. How can I make it NOT generate a random sting on a reload? I have not gotten anything with searches due to the limited queries.

You may use LocalStorage.
The code may look like :
var lastTimeGenerated = window.localStorage.getItem('lastTimeGenerated') === null
? false
: parseInt(window.localStorage.getItem('lastTimeGenerated'));
var generateInterval = 5000;
function dec2hex(dec) {
return dec < 10 ? "0" + String(dec) : dec.toString(16);
}
function generateId(len) {
var arr = new Uint8Array((len || 40) / 2);
window.crypto.getRandomValues(arr);
return Array.from(arr, dec2hex).join("");
}
function launchIntervalFnc() {
intervalFnc();
setInterval(intervalFnc, generateInterval);
}
function intervalFnc() {
var random = generateId(64);
document.getElementById("password").innerHTML = random;
window.localStorage.setItem('lastTimePassword', random);
window.localStorage.setItem('lastTimeGenerated', new Date().getTime());
}
if (lastTimeGenerated !== false && lastTimeGenerated + generateInterval > new Date().getTime()) {
document.getElementById("password").innerHTML = window.localStorage.getItem('lastTimePassword');
setTimeout(launchIntervalFnc, generateInterval - (new Date().getTime() - lastTimeGenerated));
} else {
launchIntervalFnc();
}
<div id="password"></div>

Resolve a promise after CountUp.js is finished counting

let's say we want to animate a count up from 10 to 100, using CountUp.js we should do something like this:
The question is how can I resolve a promise after the counting has finished.
createMainCountUp(); // initiate once
function createMainCountUp(){
const div = document.createElement("div");
div.id = "percentCounterTarget";
document.body.appendChild(div);
}
promisedFunc(); // this is a function I want
async function promisedFunc() {
console.log('counting has started...');
await Counting(); // I want to resolve this function when counting has finished
console.log('counting has finished!');
}
// here is the main function to start counting
function Counting(){
dial = new CountUp('percentCounterTarget', 10, 100, 4, 5);
dial.start();
//easing dial function
function CountUp(target, startVal, endVal, decimals, duration, options) {
var self = this;

};
// extend default options with passed options object
if (options && typeof options === 'object') {

Note: the StackOverflow snippet not showing the logs correctly. the code works fine.
Since CountUp.start() can take a callback function, you could create and return a Promise that calls the resolve function once the countdown is finished.
function counting() {
return new Promise((resolve, reject) => {
const dial = new CountUp(...);
dial.start(resolve);
});
}
Edit: Once the countdown is finished CountUp will call the callback function that you pass into .start(). You can see this in the copy of CountUp.js you posted in your snippet - at the comment "whether to continue" in self.count, it calls the callback function once the countdown is finished progressing. We can utilize this in a promise by calling resolve once the countdown is complete.

Values won't change when I select on dropdown?

I have a function which creates values for time as I am trying to calculate them, however when I try and change a drop down times I the values don't change as they just stay at 7. The function only loads the default values (time) which is 7 as it is 7 am.
As you can see from the screenshot when the form is loaded it has a time of 7am with the value of 7, but when I change the time to 8:00 it does not show the proper value of 8 and stays at a value of 7
Here is my code:
function _slicedToArray(arr, i) { return _arrayWithHoles(arr) || _iterableToArrayLimit(arr, i) || _nonIterableRest(); }
function _nonIterableRest() { throw new TypeError("Invalid attempt to destructure non-iterable instance"); }
function _iterableToArrayLimit(arr, i) { var _arr = []; var _n = true; var _d = false; var _e = undefined; try { for (var _i = arr[Symbol.iterator](), _s; !(_n = (_s = _i.next()).done); _n = true) { _arr.push(_s.value); if (i && _arr.length === i) break; } } catch (err) { _d = true; _e = err; } finally { try { if (!_n && _i["return"] != null) _i["return"](); } finally { if (_d) throw _e; } } return _arr; }
function _arrayWithHoles(arr) { if (Array.isArray(arr)) return arr; }
var timeStringToValue = function timeStringToValue(timeStr) {
var _timeStr$match = timeStr.match(/(\d+):(\d+) ([ap]m)/),
_timeStr$match2 = _slicedToArray(_timeStr$match, 4),
hours = _timeStr$match2[1],
minutes = _timeStr$match2[2],
ampm = _timeStr$match2[3];
var ampmHourModifier = ampm === 'pm' ? 12 : 0;
return Number(hours) + ampmHourModifier + minutes / 60;
};
var startMonTimeStr = $('.start-time-monday option:selected').text();
var FinishtMonTimeStr = $('.finish-time-monday option:selected').text();
var startMonValue = timeStringToValue(startMonTimeStr);
console.log(timeStringToValue(startMonTimeStr));
console.log(timeStringToValue(FinishtMonTimeStr));

Issue with returning a string

I have written this code to get the value of the Timer in a div :
var timerGenerator = (function() {
var time = {
centiSec: 0,
secondes: 0,
minutes: 0,
hours: 0
};
var container = document.createElement("div");
var timeDisplay = function() {
function smoothDisplay(value) {
return (value < 10 ? '0' : '') + value;
}
return "" + smoothDisplay(this.hours) + ":" + smoothDisplay(this.minutes) + ":" + smoothDisplay(this.secondes) + "." + smoothDisplay(this.centiSec);
};
var boundTimeDisplay = timeDisplay.bind(time);
var timeUpdate = function() {
container.innerHTML = boundTimeDisplay();
//console.log(container);
this.centiSec++;
if(this.centiSec === 100) {
this.centiSec = 0;
this.secondes++;
}
if(this.secondes === 60) {
this.secondes = 0;
this.minutes++;
}
if(this.minutes === 60) {
this.minutes = 0;
this.hours++;
}
};
var boundTimeUpdate = timeUpdate.bind(time);
window.setInterval(boundTimeUpdate,10);
console.log(container);
return container;
})();
This code works when I link the var timerGenartor with a div. But, now I would like to return the var container into a string. So I changed my code to this : (I just changed the initialization of container and this value)
var timerGenerator = (function() {
var time = {
centiSec: 0,
secondes: 0,
minutes: 0,
hours: 0
};
var container = "";
var timeDisplay = function() {
function smoothDisplay(value) {
return (value < 10 ? '0' : '') + value;
}
return "" + smoothDisplay(this.hours) + ":" + smoothDisplay(this.minutes) + ":" + smoothDisplay(this.secondes) + "." + smoothDisplay(this.centiSec);
};
var boundTimeDisplay = timeDisplay.bind(time);
var timeUpdate = function() {
container = boundTimeDisplay();
//console.log(container);
this.centiSec++;
if(this.centiSec === 100) {
this.centiSec = 0;
this.secondes++;
}
if(this.secondes === 60) {
this.secondes = 0;
this.minutes++;
}
if(this.minutes === 60) {
this.minutes = 0;
this.hours++;
}
};
var boundTimeUpdate = timeUpdate.bind(time);
window.setInterval(boundTimeUpdate,10);
console.log(container);
return container;
})();
With this modification nothing is returned or display in the console and I don't understand why. However, the comment "console.log" gives me good the timer. So, why the first console.log displays the good result and not the second one ?
The working code as you expected with two JS functions
// JS 1
var timerGenerator = (function() {
var time = {
centiSec: 0,
secondes: 0,
minutes: 0,
hours: 0
};
var container = "";
var timeDisplay = function() {
function smoothDisplay(value) {
return (value < 10 ? '0' : '') + value;
}
return "" + smoothDisplay(this.hours) + ":" + smoothDisplay(this.minutes) + ":" + smoothDisplay(this.secondes) + "." + smoothDisplay(this.centiSec);
};
var boundTimeDisplay = timeDisplay.bind(time);
var timeUpdate = function() {
container = boundTimeDisplay();
//console.log(container);
this.centiSec++;
if(this.centiSec === 100) {
this.centiSec = 0;
this.secondes++;
}
if(this.secondes === 60) {
this.secondes = 0;
this.minutes++;
}
if(this.minutes === 60) {
this.minutes = 0;
this.hours++;
}
return container;
};
var boundTimeUpdate = timeUpdate.bind(time);
return boundTimeUpdate;
})();
// JS 2
var spanGenerator = (function() {
var container = document.createElement('span');
window.setInterval(function(){
container.innerHTML = timerGenerator();
}, 10);
return container;
})();
document.getElementById('timer').appendChild(spanGenerator);
<div id="timer"></div>
It can be because your container is empty as it is initialized in timeUpdate function which is eventually called 10ms later(for the first time) because of the setInterval. U will have to call the timeUpdate function before putting it in setInterval.

how to implement
html
<input type="date" data-initial-day="20" data-initial-year="2010" data-initial-month="64" />
<!-- Required scripts -->
<script src='https://code.jquery.com/jquery-2.1.0.min.js'></script>
<script src='../src/cross-datepicker.js'></script>
<script>
$(function() {
$("input[type='date']").cdp();
});
</script>
the problem is that the code works great when defined data-initial-year for month and day also but when i want to show the default none selected date like select day select month and select year it shows blank or 0 .
i dont know how to solve this i have tried to solve the problem by adding some text into the js file but no help .
if you can suggest me something it would be great.
The plugin code needs to check if an entry is valid before setting it.
First off, set the addNullOption to true so that a "Select" text is visible.
$(function() {
$("input[type='date']").cdp({
addNullOption : true,
nullOptionText: "Select"
});
});
Then modify the last function $.fn.cdp.statics with the "check valid" code included below (demo):
$.fn.cdp.statics = {
fns: {
set: function(e, arg) {
var st = $.fn.cdp.statics,
obj = e.data("cross-datepicker"),
y,m,d;
if($.isArray(arg)) {
y = arg[0];
m = arg[1];
d = arg[2];
}
else if(typeof arg === 'string') {
var array = arg.split("-");
y = parseInt(array[0]);
m = parseInt(array[1]);
d = parseInt(array[2]);
}
else {
y = arg.year || arg.y;
m = arg.month || arg.m;
d = arg.day || arg.d;
}
// check valid
if ( obj.inputs.y.find('option[value="' + y + '"]').length ) {
obj.inputs.y.val(String(y));
}
if ( obj.inputs.m.find('option[value="' + m + '"]').length ) {
obj.inputs.m.val(String(m));
}
if ( obj.inputs.d.find('option[value="' + d + '"]').length ) {
obj.inputs.d.val(String(d));
}
obj.updateInput();
}
}
};
To show "Select" in the other selects, I ended up adding the following code because the year select didn't have a null option:
if (o.addNullOption) {
y.append("<option value='0'>"+o.nullOptionText+"</option>");
}
and changing the "check valid" code to:
// check valid
y = obj.inputs.y.find('option[value="' + y + '"]').length ? y : 0;
obj.inputs.y.val(String(y));
m = obj.inputs.m.find('option[value="' + m + '"]').length ? m : 0;
obj.inputs.m.val(String(m));
d = obj.inputs.d.find('option[value="' + d + '"]').length ? d : 0;
obj.inputs.d.val(String(d));

how to break a timer while it's not being used anymore

I have problem with removing a timer while it not being used anymore in javascript ?
let say we have a variable tm for the timer and set it with window.setInterval, while it still running we replace it by a new setInterval, how possible to get rid of the first setInterval ?
example code
var tm = setInterval(function(){
console.log('tm1')
}, 10);
tm = setInterval(function(){
console.log('tm2')
}, 10)
this is the real problem

this how the problems came up;
var color = 'rgba('+($(1).randomize(0,255)+',')+
($(1).randomize(0,255)+',')+
($(1).randomize(0,255)+',')+
'1)';
var bcolor = 'rgb('+($(1).randomize(0,255)+',')+
($(1).randomize(0,255)+',')+
($(1).randomize(0,255)+',')+
')';
var motion = new hd.classes.motion(box,'',('height:'+($(1).randomize(10,50))+
'px;border-color:'+bcolor+
';background-color:'+color+
';left :'+((e.x || e.clientX)-(box.rectangle().width/2))+
';top : '+((e.y || e.clientY)-(box.rectangle().height/2))+
';border-top-width:'+($(1).randomize(0,50))),
2,'circle','easeinout',1, function(e){
status.html('Idle');
});
motion.play();
while variable motion has been referenced with an motion class (animation), how possible to stop the first motion's timer if it being replaced with new motion class(animation)
Really easy! clearInterval(tm). If you call them different names, you will be able to differentiate between them.
