Question

I have been trying to fix this script for more than an hour and still can’t get it to work. It is a loop performing animate and html jquery events in a setInterval.

Here is the fiddle: http://jsfiddle.net/GNrL3/

Here is the code (same as fiddle but some prefer to have it here):

$(document).ready(function() {

var i = 1;
var startinterval = 0;

$('#clickhere').click(function() {
    startinterval = setInterval("curvalues()", 1000);
});

function curvalues() {
    if ($i == 20) {
        clearInterval(startinterval);
    }
    else {
        $("#square").animate({
            "left": "+=30px"
        }, "slow");
        $("#text").html("Barracks");
        $i++;
    }
}

});

<div id="square" style="position:absolute;height:30px;width:30px;background-color:#F07014;"></div>
<br /><br /><br /><br /><br />
<div id="text" style="height:30px;width:100px;border:1px solid #000">Text box</div>
<br /><br />
<input type="button" value="Start" id="clickhere"/>

My belief is that the issue concerns the setInterval of the function, but still, the syntax seems good to me…

Answer 1

Change this line:

startinterval = setInterval("curvalues()", 1000);

To this:

startinterval = setInterval(curvalues, 1000);

Or this:

startinterval = setInterval(function() { curvalues(); callSomethingElse(); }, 1000);

And get rid of the $ in front of i. There’s no need for that.
