Question

I have created an image upload control, however i’m not satisfied with its look. I only want the button shown not the text box to the left of the button. Is there any way I can just use the normal button control or linkbutton control to to get the file dialog to open.

I got this simple example working in Firefox 4, IE6 and IE9 but unfortunately it doesn’t work in Chrome 10.

<script type="text/javascript">
    $(document).ready(function () {
        var cnt = 1; // for interfering id's
        $('#upload').click(function () {

            // adds a new file-browser upload control and calls the AppendFilesToList with file information
            $("#files").append("<input type=\"file\" id=\"fileupload" + cnt + "\" onchange=\"javascript:AppendFilesToList(this.value);\" style=\"display:none;\" />");
            document.getElementById("fileupload" + cnt).click(); // calls the browsers file-upload dialog

            cnt++;
        });
    });
    // appends file information to a div
    function AppendFilesToList(evt) { $("#listfiles").append(evt + "<br/>"); }
</script>

<div id="files"></div>
<div id="listfiles"></div>

<br />

<input type="button" id="upload" value="Select files" />
