copied!<p>Solution: use <code>setInterval</code> and <code>clearInterval</code> instead of timeout, because setTimeout only executes the closure function once, or <code>setTimeout</code> in your closure function.</p> <p>Example for using <code>setTimeout</code> in the function itself:</p> <pre><code>$('.bid-up').live('mousedown',function() { var button = $(this); function asd(){ var number = button.parent('div').siblings('#bid-child-container-2').find('#bid-price').val(); var newnumber = number.split('.'); var on = button.attr('data-on'); button.siblings('#bid-down').attr('data-on','1'); if(newnumber[1]<9) { var first = newnumber[0]; var second = parseInt(newnumber[1])+1; } if(newnumber[1]==9) { var first = parseInt(newnumber[0])+1; var second = 0; } var finalnumber = first+'.'+second; button.parent('div').siblings('#bid-child-container-2').find('#bid-price').val(finalnumber); timeoutId = setTimeout(asd, 20); } timeoutId = setTimeout(asd, 20); }).bind('mouseup mouseleave', function() { clearTimeout(timeoutId); }); </code></pre> <p>example using <code>setInterval</code> and <a href="http://api.jquery.com/data/" rel="nofollow"><code>data</code></a> to store interval id.</p> <pre><code>$('.bid-up').live('mousedown',function() { var button = $(this); button.data('interval', setInterval(function (){ var number = button.parent('div').siblings('#bid-child-container-2').find('#bid-price').val(); var newnumber = number.split('.'); var on = button.attr('data-on'); button.siblings('#bid-down').attr('data-on','1'); if(newnumber[1]<9) { var first = newnumber[0]; var second = parseInt(newnumber[1])+1; } if(newnumber[1]==9) { var first = parseInt(newnumber[0])+1; var second = 0; } var finalnumber = first+'.'+second; button.parent('div').siblings('#bid-child-container-2').find('#bid-price').val(finalnumber); }, 20)); }).bind('mouseup mouseleave', function() { clearInterval(button.data('interval')); }); </code></pre>
