Is it possible to read some key in web.config file from extjs ?

You could use an input tag and load the file with HTML 5 so extJS might help.

However file must be visible to the client and server. If the web.config you are referring to is the configuration for a ASP.net site on an IIS server this could have serious security issues.

<input type="file" id="files" name="files[]" multiple /> <output id="list"></output>

function handleFileSelect(evt) {
var files = evt.target.files; // FileList object
// Loop through the FileList and render image files as thumbnails.
for (var i = 0, f; f = files[i]; i++) {
// Only process image files.
if (!f.type.match('image.*')) { continue; } var reader = new FileReader();
// Closure to capture the file information.
reader.onload = (function(theFile) { return function(e) {
// Render thumbnail.
var span = document.createElement('span'); span.innerHTML = ['<img class="thumb" src="', e.target.result, '" title="', escape(theFile.name), '"/>'].join(''); document.getElementById('list').insertBefore(span, null); }; })(f); // Read in the image file as a data
URL. reader.readAsDataURL(f); } } document.getElementById('files').addEventListener('change', handleFileSelect, false);

Not really

That file should really not be exposed to editing in a web environment.

The safest way is edit it via text editor and NOT expose it to the web server.

It exposes your entire site to hacks.
