Can I get the image and load via ajax into div

Question

I have the code below and what I need to do is load the image from the href into a div via ajax... Any help appreciated. I believe that load() can\'t load images like this?<

Answer 1

You have to also remove the currently appended image. Here it is with a click event and Image instead of appending markup.

$('#list li a').click(function () {
    var url = $(this).attr('href'),
    image = new Image();
    image.src = url;
    image.onload = function () {
        $('#image-holder').empty().append(image);
    };
    image.onerror = function () {
        $('#image-holder').empty().html('That image is not available.');
    }

    $('#image-holder').empty().html('Loading...');

    return false;
});

If you want to change image dynamically use dom What you need to do is change the img src attribute

say img_div is your parent element then

var im = document.createElement('img');
im.src = 'image_path1';
img_div.appendChild(im);

on some event if you want to change this image

im.src = 'image_path2'

Okay. Messy but it works perfectly. A few tweak like adding the images as background images. Here it is and I hope it helps someone else! Thanks so much everyone.

<script type="text/javascript">
$(function(){
    var list = $("#list");
    var li = list.children();
    var lengthMinusOne = li.length - 1;
    var index = 0;
    var num = $("#list li").length;
    var prevLi = $(li[0]).css("background-color", "gray");

    $("#next").click(function(){
       index++;
       if (index > lengthMinusOne) index = 0;
       prevLi.css("background-color","white");
       prevLi = $(li[index]).css("background-color", "gray");

       //Trigger a href click
       $(prevLi).children('a').trigger('click');

       //Display class in console
       var myClass = $(prevLi).attr("class");
       console.log(myClass);
    });
    $("#prev").click(function(){
       index--;
       if (index < 0) index = lengthMinusOne;
       prevLi.css("background-color","white");
       prevLi = $(li[index]).css("background-color", "gray");

       //Trigger a href click
       $(prevLi).children('a').trigger('click');

       //Display class in consol
       var myClass = $(prevLi).attr("class");
       console.log(myClass);
    });


    //Loader
    loader = $('#loader');
    loader.hide();
    var firstImg = $('<img />');
    $(firstImg).attr('src',$('#list li a').attr('href'));
    $('#image-holder').append(firstImg);

    //get image and load into div
    $('#list li a').click(function(event) {                        
        //Add class to image within holder
        oldImg = $('#image-holder img').addClass('old');
        newImg = $('<img />');

        $(newImg).attr('src',$(this).attr('href'));
        //remove old image and show loader
        $(oldImg).fadeOut().remove();
        loader.show();

        $(newImg).bind({
            load: function() {          
                //console.log("Image loaded");
                //Hide loader before fading in image
                loader.hide();
                $('#image-holder').append(newImg).hide().fadeIn(1300);
            },
            error: function() {
                //console.log("Error thrown, image didn't load, probably a 404.");
            }
        });

        event.preventDefault();
    });


})
</script>

This would be the first thing I would try, I'm also a bit of a beginner as well though:

var image = $('<img></img>');
image.attr('src', 'images/image1.jpg');
$('#image-holder').append(image);
