I am using valums-file-uploader plugin. It allows me to upload files using ajax. I have a problem with it. I have the following script-

<input type="text" id="Gaurav" name="Gaurav" />
<script src="fileuploader.js" type="text/javascript"></script>
<script>
    function createUploader(){
        var uploader = new qq.FileUploader({
            element: document.getElementById('file'),
            action: 'do-nothing.php',
            params:{param: document.getElementById('Gaurav').value},
            allowedExtensions: ['jpg', 'jpeg', 'png', 'gif'],
            minSizeLimit: 1,
            debug: false
        });
    }

    // in your app create uploader as soon as the DOM is ready
    // dont wait for the window to load  
    window.onload = createUploader;     
</script>

In it, I want to set the value of param entered by the user. The code is working properly for default value of Gaurav, but didn't work for user inputted value.
