Hello Experts,

On a page i have a slideshow. I want to add text to serve as a caption of the image.
In total there are only two photo so this should not be a long script.....

What i did using my very basic knowledge in jquery is simply use show/hide with the delay.

Like so

        $('#caption1').fadeIn(5000);
	$('#caption1').delay(12000).fadeOut(500);

        $('#caption2').fadeIn(5000);
	$('#caption2').delay(12000).fadeOut(500);	

Open in new window


You see in need to follow the time of the photo as they appear and cycle.
- when the first photo appear show caption1
- when the second photo appears hide caption1 and show caption2
- cycle the same timing... first photo appears again.....

Please if someone can help?

something like

var total = $("[id^='caption']").size();
function showcaption(id){
$("#"+id).fadeIn(5000, function(){
   setTimeout("getNextId(" + id + ")", 12000);
});
}

function getNextId(id)
{
  $("#"+id).fadeOut(2000, function(){
   if ( $("#"+id).index() == size()-1 )
   {
        id = $( "[id^='caption']").first().attr("id");
   }
   else
   {
        id = $("#"+id).next( "[id^='caption']").attr("id");
   }
   setTimeout("showcaption(" + id + ")", 12000);
});
}

you can do something like following


<html>
<head>
<script script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script>
$(function() {
     $("#divImage-Slide div:first").hide();
     setInterval("SwapImageWithCaption()", 1000);
});
function SwapImageWithCaption()
{
    $("#divImage-Slide>div").toggle()
}
</script>      
</head>
<body>
<div id="divImage-Slide">
   <div id="divImage1">
       <img src="Desert.jpg" height="308px" width="308px" >     
       <div id="divCaption1">Caption 1 - Desert</div>
   </div>
   <div id="divImage2">
        <img src="Chrysanthemum.jpg" height="308px" width="308px">      
        <div id="divCaption1">Caption 2- Chrysanthemum</div>
   </div>
</div>

</body>
</html>

hope this will solve your problem.

Hi again,

gurvinder372, I tried your solution. nothing happens.

Lalit-Chandra, I am only looking for the solution on the caption not the slideshow.

I will set the time corresponding the two photo.

All i am after is the option to set a time for the "caption" 1 to appear then fade... the the time for "caption2" then hide... then to cycle the same function (show/hide) in the same timing.

thanks again guys!

Ok. you want the show/hide effect only on the caption not with the image.So, in that scene you can simple remove the image from the sample i have presented. It will start the animation with caption only.

Hi Lalit-Chandra,

as in my previous reply, again, thank you!

here is the code below, as i set it.

the second caption gets to show first, do you know why?

Can i add fadeIn, fadeOut or slideLeft SlideRight?

$(function() {
     $("#captions div:first").hide();
     setInterval("SwapImageWithCaption()", 5000);
});
function SwapImageWithCaption()
{
    $("#captions>div").toggle()
}

</div>

hello

the second caption is showing first as because i have make the first caption hidden in my code at the first time.
To make 1 caption visible , do some script change

        $("#captions div:first").hide();
To

        $("#divImage-Slide>div:last").hide();

The above will make frist caption visible first.

As far as Fade In/Out effect is concerned,you have to do some more changing's to achieve that.you take a review of the below code...


<html>
<head>
<script script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script>
$(function() {
$("#divImage-Slide>div:last").hide();
setInterval("SwapImageWithCaption()", 1000);
     
});
function SwapImageWithCaption()
{
$("#divImage-Slide>div").fadeToggle()
}

</script>      

</head>

<body>

<div id="divImage-Slide" style=" width: 100px;height: 100px;position: relative;">
   <div id="divImage1" style=" width: 100%;height: 100%;position: absolute;top: 0;left: 0;">
       <img src="Desert.jpg" height="308px" width="308px" >     
       <div id="divCaption1">Caption 1 - Desert</div>
   </div>
   <div id="divImage2" style=" width: 100%;height: 100%;position: absolute;top: 0;left: 0;">
        <img src="Chrysanthemum.jpg" height="308px" width="308px">      
        <div id="divCaption1">Caption 2- Chrysanthemum</div>
   </div>
</div>

</body>
</html>
         


Hope this will do your required needs.
