Stop-clear interval

Copy linkTweet thisAlerts:
Mar 08.2020

Hi,
I have checkBox in my code which allow me to set interval.
When checkBox is checked, this funcion works well but don’t know why won’t stop when checkBox is unchecked?
If i add alert(“uncecked”) in else block and uncheck listBox,alert popup.So something is about Interval.clearInterval();
Thnaks for any help.

[code]
$(function()
{

$(‘[name=”updataCheckBox”]’).change(function()
{

if ($(this).is(‘:checked’)) {

var Interval=setInterval(function(){

$(“#updateButton”).click();

},2000);

}
else
{
Interval.clearInterval();
}
});
});
[code]

@SempervivumMar 08.2020 — There are two issues in your code:
  • 1. The variable Interval is defined inside the scope of the anonymous function of the change handler. Therefore it is not available when the button is unchecked. It has to be defined outside of that function.

  • 2. The variable Interval has to be handed over to the function clearInterval() as a parameter.
    $(function () {
    var Interval;
    $('[name="updataCheckBox"]').change(function () {
    if ($(this).is(':checked')) {
    Interval = setInterval(function () {
    $("#updateButton").click();
    }, 2000);
    }
    else {
    clearInterval(Interval);
    }
    });
    });
