Guardian-Mage Posted August 2, 2007 Share Posted August 2, 2007 I have a slideshow that is different than others. Part of it is it needs to be automated. var slideLength = 27; var lock = false; var run; var idvar = '001'; function changeImage(dir) { if (document.images) { curImg = curImg + dir; if (curImg > slideLength) { curImg = 1; } if (curImg < 1) { curImg = slideLength; } if (document.getElementById(curImg)) { var nextImage = document.getElementById(curImg).innerHTML; } else { curImg++; } document.getElementById('slideshow').innerHTML = nextImage; document.getElementById('slide').value = curImg; } } This will take the content of a table and load it. But say I have objects with the ID 3,4,5,6,8 but no 7. My script needs to skip it. Part of what I have works. It will skip the number but than it says the nextImage is not defined. I need it so when it says else { curImg++; } It will than retry the if loop to see if the new object exists Link to comment https://forums.phpfreaks.com/topic/63056-solved-javascript-if-statementif-object-exists/ Share on other sites More sharing options...
