horizontal scrolling div onclick with javascript o

问题:

I have spent the last two days looking for a simple javascript or jquery code for this. I want to incorporate a horizontal scrolling div using javascript or jquery to display images and descriptive text for the work page of my web portfolio.

It would function very similar to the glide-onclick scrolling shown here: http://www.dyn-web.com/code/scroll/demos.php#horiz Unfortunately that code license is $40, and I am a broke student.

On loading of the page, three portfolio images will be shown. Extras are hidden in the overflow to the right. Onclick of a left arrow (I can create), a new image slide comes into view from the right. A right arrow click sends it back into overflow. I don't want scrollbars, just arrows controlling the slides.

Any help is much appreciated. Thanks.

You can just use code like this:

function FixMargin(left) {
    $(this).css("left", left);
}

$(document).ready(function () {

$('#rightbutton').click(function () {
    var left = parseInt($("#bitToSlide").css('left'), 10);
    $("#bitToSlide").animate({ left: left - pageWidth }, 400, FixMargin(left - pageWidth));
});

$('#leftbutton').click(function () {
    var left = parseInt($("#bitToSlide").css('left'), 10);
    $("#bitToSlide").animate({ left: left + pageWidth }, 400, FixMargin(left + pageWidth));
});

}

where your html looks like this:

<div id="slideleft" class="slide">
    <div class="inner" id="bitToSlide" style="width:1842px">
        <table border="0" cellpadding="0" cellspacing="0">
            <tr valign="top">
                <td id="page1" style="width: 614px">
                </td>

                <td id="page2" style="width: 614px">
                </td>
            </tr>
        </table>
    </div>
</div>

and your css looks like this:

.slide
{
position:relative;
overflow:hidden;
height:365px;
width:597px;
margin:1em 0;
background-color:#E9ECEF;
border:0px
}

.slide .inner
{
position:absolute;
left:0;
bottom:0;
height:365px;
padding:0px;
background-color:#E9ECEF;
color:#333
}

I wrote the above a really long time ago - so you probably want to update it a bit (replace the table's with div's for example) but it works.

You obviously need the two buttons on there as well

There are a lot of jQuery plugins which allow you to do this very easily. For ex: http://slidesjs.com/

Hope this helps.

You can do something like this. Not tested code but just giving you a hint.

<div id="imageContainer">
  <div id="imageWrapper">
    <img />
    <img />
  </div>
  <span id="left">Left</span>
  <span id="right">right</span>
</div>

var imageWidth = 200;
$("#left").click(function(){
  $("#imageWrapper").animate({marginLeft:"-="+imageWidth}, 500);
  //Offcourse you need to handle the corner cases when there is not image to move left
});

$("#right").click(function(){
  $("#imageWrapper").animate({marginLeft:"+="+imageWidth}, 500);
});

You can have a look to iscroll 4.

You have a scrollTo method or scrollToElement method...
