    image rollover with link

    Hi guys,

    Hope you can help with a tricky one for this newbie!

    I am using this line of code:
    Code:
    <a href="large_photo.jpg" rel="enlargeimage" rev="targetdiv:main_photo" border="0"><img border="0" src="thumbnail.jpg"></a>
    This is working great so that when someone rolls over the thumbnail, the larger image is loaded into the div calls main_photo.

    However, when rolling over the thumbnail a user can also CLICK (the hand icon comes up) and if they click on the thumbnail they get taken to a new page just displaying the photo.

    Is there any way to stop them being able to click, i.e. so they can only hover?

    Or if not, if there a way I can make it link to a PAGE instead (that I can style etc) rather than being a link just to the photo?

    Thanks - would rally appreciate any help!

    Rob.

    Can you post the JavaScript that's handling the hover? Most likely, you can simply add a "return false;" to the end of your function.

    Hi, thanks for the reply. Here's the JS:

    Code:
    jQuery.noConflict()
    
    jQuery.thumbnailviewer2={
    		loadmsg: '<img src="spinningred.gif" /><br />Loading Large Image...', //HTML for loading message. Make sure image paths are correct
    
    	/////NO NEED TO EDIT BEYOND HERE////////////////
    
    	dsetting: {trigger:'mouseover', preload:'yes', fx:'fade', fxduration:500, enabletitle:'yes'}, //default settings
    	buildimage:function($, $anchor, setting){
    		var imghtml='<img src="'+$anchor.attr('href')+'" style="border-width:0" />'
    		if (setting.link)
    			imghtml='<a href="'+setting.link+'">'+imghtml+'</a>'
    		imghtml='<div>'+imghtml+((setting.enabletitle!='no' && $anchor.attr('title')!='')? '<br />'+$anchor.attr('title') : '')+'</div>'
    		return $(imghtml)
    	},
    
    	showimage:function($image, setting){
    		$image.stop()[setting.fxfunc](setting.fxduration, function(){
    			if (this.style && this.style.removeAttribute)
    				this.style.removeAttribute('filter') //fix IE clearType problem when animation is fade-in
    		})
    	}
    	
    }
    
    
    jQuery.fn.addthumbnailviewer2=function(options){
    	var $=jQuery
    
    	return this.each(function(){ //return jQuery obj
    		if (this.tagName!="A")
    			return true //skip to next matched element
    
    		var $anchor=$(this)
    		var s=$.extend({}, $.thumbnailviewer2.dsetting, options) //merge user options with defaults
    		s.fxfunc=(s.fx=="fade")? "fadeIn" : "show"
    		s.fxduration=(s.fx=="none")? 0 : parseInt(s.fxduration)
    		if (s.preload=="yes"){
    			var hiddenimage=new Image()
    			hiddenimage.src=this.href
    		}
    		var $loadarea=$('#'+s.targetdiv)
    		var $hiddenimagediv=$('<div />').css({position:'absolute',visibility:'hidden',left:-10000,top:-10000}).appendTo(document.body) //hidden div to load enlarged image in
    		var triggerevt=s.trigger+'.thumbevt' //"click" or "mouseover"
    		$anchor.unbind(triggerevt).bind(triggerevt, function(){
    			if ($loadarea.data('$curanchor')==$anchor) //if mouse moves over same element again
    				return false
    			$loadarea.data('$curanchor', $anchor)
    			if ($loadarea.data('$queueimage')){ //if a large image is in the queue to be shown
    				$loadarea.data('$queueimage').unbind('load') //stop it first before showing current image
    			}
    			$loadarea.html($.thumbnailviewer2.loadmsg)
    			var $hiddenimage=$hiddenimagediv.find('img')
    			if ($hiddenimage.length==0){ //if this is the first time moving over or clicking on the anchor link
    				var $hiddenimage=$('<img src="'+this.href+'" />').appendTo($hiddenimagediv) //populate hidden div with enlarged image
    				$hiddenimage.bind('loadevt', function(e){ //when enlarged image has fully loaded
    					var $targetimage=$.thumbnailviewer2.buildimage($, $anchor, s).hide() //create/reference actual enlarged image
    					$loadarea.empty().append($targetimage) //show enlarged image
    					$.thumbnailviewer2.showimage($targetimage, s)
    				})
    			$loadarea.data('$queueimage', $hiddenimage) //remember currently loading image as image being queued to load
    			}
    
    			if ($hiddenimage.get(0).complete)
    				$hiddenimage.trigger('loadevt')
    			else
    				$hiddenimage.bind('load', function(){$hiddenimage.trigger('loadevt')})
    			return false
    		})
    	})
    }
    
    jQuery(document).ready(function($){
    	var $anchors=$('a[rel="enlargeimage"]') //look for links with rel="enlargeimage"
    	$anchors.each(function(i){
    		var options={}
    		var rawopts=this.getAttribute('rev').split(',') //transform rev="x:value1,y:value2,etc" into a real object
    		for (var i=0; i<rawopts.length; i++){
    			var namevalpair=rawopts[i].split(/:(?!\/\/)/) //avoid spitting ":" inside "http://blabla"
    			options[jQuery.trim(namevalpair[0])]=jQuery.trim(namevalpair[1])
    		}
    		$(this).addthumbnailviewer2(options)
    	})
    })
    Thanks!

    Rob.
