Call a JavaScript Function at Regular Intervals | Execute Function Every n Seconds

Introduction: 

Here I will explain how to call a JavaScript function at regular intervals of time or run/execute JavaScript function every 10 seconds or execute JavaScript function at specific time in asp.net.



To execute function repeatedly with fixed time delay we have a function with two parameters called setInterval(functionname, timedelay).

In this function we need to call the required function in functionname field and we need to set the required time delay to execute the function in timedelay field. If you want to see it in example you need to write the code like as shown below

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Run JavaScript function at specific intervals of time</title>
<script type="text/javascript">
var count=0;
function changeColor() {

// Call function with 500 milliseconds gap
setInterval(starttimer, 500);
}
function starttimer() {
count += 1;
var oElem = document.getElementById("divtxt");
oElem.style.color = oElem.style.color == "red" ? "blue" : "red";
document.getElementById("lbltxt").innerHTML = "Your Time Starts: "+count;
}
</script>
</head>
<body>
<div id="divtxt">
<label id="lbltxt" style="font:bold 24px verdana" />
</div>
<button onclick="changeColor();">Start Timer</button>
</body>
</html>
