Hi, Im trying to run the showPic function without putting any JS into HTML(when i used onclick = showPic() return false, it worked fine). I added prepareGallery function for this reason and I cant get it working. I think I can see it changes the pics but link will be executed also. Anyone got an idea where I made the mistake? <body><h1>Snapshots</h1><ol id="links"><li><a href="benfica.jpg" title="benfica">Benfica</a></li><li><a href="yamaha.jpg" title="yamaha">Yamaha</a></li><li><a href="island.jpg" title="island">Island</a></li><li><a href="opossum.JPG" title="opossum">Opossum</a></li></ol><img id="placeholder" src="1.jpg" alt="my image gallery" /><p id="desc">Choose an image</p></body>function showPic(whichpic) {if (!document.getElementById("placeholder")) return false; var source = whichpic.getAttribute("href");var placeholder = document.getElementById("placeholder");placeholder.setAttribute("src",source);if (!document.getElementsById("desc")) return false;var titletext = whichpic.getAttribute("title");var desc = document.getElementById("desc"); desc.firstChild.nodeValue = titletext;return false;}function prepareGallery(){if (!document.getElementById || !document.getElementsByTagName) return false;var links = document.getElementById("links");var actLinks = links.getElementsByTagName("a");for (var i = 0; i < actLinks.length; i++){actLinks[i].onclick = function(){showPic(this);return false;}}}window.onload = prepareGallery;

I am not so experienced in js and as such I have this question;Here is some code: $(function() { $('.error').hide(); $(".button").click(function() { $('.error').hide(); var name = $("input#name").val(); if (name == "") { $("label#name_error").show(); $("input#name").focus(); return false; } // validate and process form here }); }); Why the if statement above has a "return false" statement in it.Is there a difference in the false statement between PHP and JS.
