cannot change width+height of image by javascript


I dynamically upload my picture. My code should run also for IE9, and on the following code, I focus on IE9 only:

    <!doctype html>
    <html>
    <head>
    <!-- <meta content="text/html; charset=UTF-8" http-equiv="Content-Type" /> -->
    <link href='http://fonts.googleapis.com/css?family=PT+Sans:400italic' rel='stylesheet' type='text/css'>  
    <link href='http://fonts.googleapis.com/css?family=PT+Sans' rel='stylesheet' type='text/css'>
    <link href='http://fonts.googleapis.com/css?family=PT+Sans:700' rel='stylesheet' type='text/css'>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js"></script>
    <title>Image preview example</title>
    <script type="text/javascript">
    var loadImageFile = (function () {
        if (navigator.appName === "Microsoft Internet Explorer") {
            return function () {
                $("#id_image").width(300);
                $("#id_image").height(300);
                $("#id_image").css("filter", "progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=image)");
                document.getElementById("id_image").filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = document.getElementById("imageInput").value;
$("#id_image").width(320); // ****** Problematic line
$('#id_image").height(350); // ****** Problematic line
            }
        }
    })();
    </script>
    <style type="text/css">
    </style>
    </head>

    <body>

    <form name="uploadForm">
    <p><input id="imageInput" type="file" name="myPhoto" onchange="loadImageFile();" /><br />
    </form>
    <img id="id_image" src="data:image/gif;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs%3D" onmousedown="return false" alt="Your picture"/>
    </body>
    </html>
  1. Why must I declare width+height before line: document.getElementById("id_image").filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = document.getElementById("imageInput").value ?

  2. I cannot put line (marked on asterisk : ** Problematic line), because it doesn't change the width+height.

How can I change the width+height instead?

Thanks :)


Solution

  • There is a delay when changing image size till it changes on screen.
