I have a slideshow on my website but there is a problem with in.

Here, my JS:

var size_ini = 1;
$(document).ready(function() {
    setInterval('$("#next").click()',10000)
    $("#next").click(function() {
        if(size_ini < 3);
        size_ini++;
        else
        size_ini = 1
        $(".sample").hide();
        $("#id" + size_ini).show();
        $("ment" + size_ini).show();
        $("ment_description" + size_ini).show();
    });
    $("#prev").click(function() {
        if(size_ini > 1)
        size_ini--;
        else
        size_ini = 3;
        $(".sample").hide();
        $("#id" + size_ini).show();
        $("ment" + size_ini).show();
        $("ment_description" + size_ini).show();
    });
});

As you can see I have a Timer of 10 sec. for slide. I have a previous and a next button. So when i clicked on one of the button the timer should stop and starts again. I have tried "clearInterval" but this doesn't work.

Can anyone tell how this works.

Here is FIDDLE.

Fiddle Demo

var size_ini = 1;
$(document).ready(function () {
    var timer = setInterval('$("#next").click()', 10000); //assign timer to a variable
    $("#next").click(function () {
        if (size_ini < 3) size_ini++;
        else size_ini = 1
        $(".sample").hide();
        $("#id" + size_ini).show();
        clearInterval(timer); //clear interval
        timer = setInterval('$("#next").click()', 10000); //start it again
    });
    $("#prev").click(function () {
        if (size_ini > 1) size_ini--;
        else size_ini = 3;
        $(".sample").hide();
        $("#id" + size_ini).show();
        clearInterval(timer); //clear interval
        timer = setInterval('$("#next").click()', 10000); //start it again
    });
});

If you're going to want to clear the interval you need to assign it to a variable, then you can clear it easily -

var myInterval = setInterval('$("#next").click()',10000);

Then clear like this -

clearInterval(myInterval);

Once the interval has been cleared make sure to reset it and assign it to a variable again if you want it to continue.

<button id="start">Start</button>
<button id="stop">Stop</button>

var timer;
$("#start").click(function() {
    timer = setInterval(function(){$("#next").trigger("click");},"500");
});
$("#stop").click(function() {
    clearInterval(timer);
});
