javascript - Show image before actually uploading it -

-

i'm using filefield upload image server on form , works fine.

but can somehow after user uses browse button load image image field (kind of preview) ? since have no access real full path, didn't find way that...

edit: shayan managed proper code this:

(in fileupload componentes change event):

    var file = uploader.fileinputel.dom.files[0];     var reader = new filereader();     reader.addeventlistener('load', function(evt) {         form.down('#imglogo').setsrc(evt.target.result);     });     reader.readasdataurl(file);

you should use filereader api , it...

    <script>     var file=new filereader(); file.readasdataurl(fileinput.files[0]); file.onload=function(evt){ var img=document.getelementbyid("myimage"); img.src=evt.target.result; }       </script>

i'm trying use netbeans (7.3.1) work on remote project. my configuration following: my local machine windows 7 laptop. doesn't have tools. in particular neither compiler nor debugger. have netbeans ide , putty example. source code, make scripts , (eventually) build results located on remote storage shared across servers , "locals". (i might switch single server storage faster don't think matters @ all.) i'm accessing using sshfs manager . sshfs manager takes server name, path on server, user name , ssh private key. in result mounts directory on server disk on windows. works fine. (although directories, possibly links, represented files in windows explorer, don't know if matters...) netbeans project located on local machine don't think matters , place remotely well. prefer keep "off source" don't have add ignores version control. in netbeans did procedure described in remote developement tutorial . seems successful. netbeans c...
