setinterval not working after clearinterval [duplicate]

Question

This question already has answers here:

Pass correct "this" context to setTimeout callback? (6 answers)

Closed 9 years ago.

I have a piece of javascript code:

var intervalId;
intervalId = setInterval(fetchData, 2000);

$('.campaign-select li').on("click", "a", function(event)
{
    window.clearInterval(intervalId);
    intervalId = setInterval(fetchData_id($(this).data('campaign-id')), 2000);
});

The first setInterval was correct, the function fetchData is correctly loaded each 2 seconds.

But when I click the .campaign-select li a element, the fetchData_id is executed but only once, not repeated as expected with setInterval.

Any help?

Thanks.

You can't pass parameter in the setInterval function.

That being said, you should try this :

$('.campaign-select li').on("click", "a", function(event){
    window.clearInterval(intervalId);
    var $this = $(this)
    intervalId = setInterval(function(){
        fetchData_id($this.data('campaign-id'))
    }), 2000);
});
