I'm trying to create a counter, that updates every 1 second. I've made a backend function that returns every 30 seconds, which is called with Ajax. The result from the call is divided by 30 and should then update the counter every 1 second for 30 seconds. How would I go about putting a sleep in the for-loop?
This is my code so far:
function getCount() {
$.ajax({
url: '@Url.Action("", "", new {area = ""})',
type: 'POST',
success: function (data) {
var newTotalCount = data.totalCount;
var newDanishCount = data.danishCount;
var newNorwayCount = data.norwayCount;
var newSwedenCount = data.swedenCount;
var newUsCount = data.usCount;
var currentTotalCount = $("#odoTotal").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
var currentDanishCount = $("#odoDk").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
var currentNorwayCount = $("#odoNo").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
var currentSwedenCount = $("#odoSe").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
var currentUsCount = $("#odoUs").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
var updateTotalCount = newTotalCount - currentTotalCount;
var updateDanishCount = newDanishCount - currentDanishCount;
var updateNorwayCount = newNorwayCount - currentNorwayCount;
var updateSwedenCount = newSwedenCount - currentSwedenCount;
var updateUsCount = newUsCount - currentUsCount;
var updateTotalPerSecond = updateTotalCount / 30;
var updateDanishPerSecond = updateDanishCount / 30;
var updateNorwayPerSecond = updateNorwayCount / 30;
var updateSwedenPerSecond = updateSwedenCount / 30;
var updateUsPerSecond = updateUsCount / 30;
getAllSales();
for (var i = 0; i < 30; i++) {
window.setTimeout(function() {
$("#odoTotal").html(currentTotalCount+updateTotalPerSecond);
$("#odoDk").html(currentDanishCount+updateDanishPerSecond);
$("#odoNo").html(currentNorwayCount+updateNorwayPerSecond);
$("#odoSe").html(currentSwedenCount+updateSwedenPerSecond);
$("#odoUs").html(currentUsCount+updateUsPerSecond);
currentTotalCount = $("#odoTotal").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
currentDanishCount = $("#odoDk").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
currentNorwayCount = $("#odoNo").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
currentSwedenCount = $("#odoSe").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
currentUsCount = $("#odoUs").text().replace(/,/g, "").replace(/(\r\n|\n|\r)/gm, "");
}, 1000);
}
}
});
}
I got a solution for that
First create a variable which you will going to increment
var x = 0;
then create an interval which will do what you wanted after an a time ended for example 5(s), This will also increment your value x
every time it run
var interval = setInterval(function() {
if (x >= 5) { // just change 5 to 30
console.log('Loop timeout ended');
return clearInterval(interval);
}
// do what ever you want
console.log('Current x: '+x);
x++;
}, 5000);
example function
function runTimeoutLoop(){
var x = 0;
var interval = setInterval(function() {
if (x >= 5) { // just change 5 to 30
console.log('Loop timeout ended');
return clearInterval(interval);
}
// do what ever you want
console.log('Current x: '+x);
x++;
}, 5000);
}
If you use Firefox 53+, or babel you can use ES2017:
async function promiseTimeout(milliseconds) {
await new Promise(resolve => setTimeout(()=>resolve(), milliseconds))
}
async function countDown(from) {
while (from) {
console.log(from--, 'seconds left');
await promiseTimeout(1000);
}
alert('countdown done');
}
countDown(10);
Here it is with babel.
