Guide to using jQuery to load an image

I am using this code to load an image and display it within a dialog box. 

<div id="image_preview" title="Client Photo Preview">
   <p><img src="" alt="client image" id="client_image_preview" /></p>
</div>

$("#client_image_preview").attr("src", imagelocation);

$('#image_preview').dialog({
    height: 'auto',
    width: 'auto',
    modal: true,
    dialogClass: 'titleless',
    buttons: { "CLOSE": function() { $(this).dialog("destroy"); } }
});

Is there a method in jQuery to display a loading gif while the image is loading?

Best regards,

Answer №1

To display a loading gif image initially in your img tag, follow these steps: preload the image using a JavaScript Image object and listen for the onload event. Once the target image finishes preloading, update the src attribute of your img tag with its URI.

<div id="image_preview" title="Client Photo Preview">
   <p><img src="loading.gif" alt="client image" id="client_image_preview" /></p>
</div>

var img = new Image();
img.onload = function() {
    $("#client_image_preview").attr("src", imagelocation);
}
img.src = imagelocation;

$('#image_preview').dialog({
    height: 'auto',
    width: 'auto',
    modal: true,
    dialogClass: 'titleless',
    buttons: { "CLOSE": function() { $(this).dialog("destroy"); } }
});
