Get full path with JS from form file type

Hey all

I have a form which allows a user to upload an image

I want to create a preview of what the page they are creating looks like, so I want to show a preview of the image on the page without uploading the image

So what I need to do is get the full path (The actual value shown in the form) to javascript

I done the following

//JavaScript bit
ShowTempImage(FormImgVal){
alert ("Val is "+FormImgVal);
}

//HTM Bit
<form method='post' action='' enctype='multipart/form-data'>
<input type='file' name='UploadImg' id='UploadImg' onclick='ShowTempImage(this.value);' />
</form>

And i get an alert saying the filename only, not the full path.

Anyone know How i can get the full path without page reload

For security reasons, I don't think you can do that. Google for an AJAX File Uploader. Then, when they click the "preview" button, use AJAX to upload the file to a temporary place, then use have the page show that temporary file.

Here is one of the many image preview scripts - http://javascript.internet.com/forms/image-upload-preview.html
