[Proto-Scripty] Re: AJAX Request: receive base64 encoded image in responseText
Is response empty in network sniffer/web inspector? Or in javascript code? The response is already empty in web inspector. Very bad You should check if it is actually written to HTTP response (maybe response is already flushed). If I return some HTML in addition to my base64 string the HTML arrives in response. There is some problem in your server code. You should see returned base64 string in response in Web Inspector/network sniffer. the js code here: http://pastebin.com/Y9SFVxKq http://pastebin.com/CeREQhtd - cleaned up version, try this, you had extra space between parameter name and value in your code, also element manipulations were ineffective. -- You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

I checked the response header and it's Content-Type: text/html; charset=UTF-8. Unfortunately I couldn't check the response because it's empty. Is response empty in network sniffer/web inspector? Or in javascript code? Printing the return-part in my controller I got the correct base64-encoded string. You should check if it is actually written to HTTP response (maybe response is already flushed). I checked prototype api docs and it says, the response is going to be eval'd before it shows up in browser. So what to do? Simply change the response content type? Is there any base64-Type? How are you processing response? Please show your code (here or in jsfiddle.net) or give a link to test site. Ajax.Response#responseText should be filled from XMLHttpRequest#responseText no matter which Content-Type is in response. -- You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

Dear Victor,
thanks for your reply. I checked the response header and it's
Content-Type:
text/html; charset=UTF-8.
Unfortunately I couldn't check the response because it's empty. Printing
the return-part in my controller
I got the correct base64-encoded string. I checked prototype api docs and
it says, the response is going to be eval'd
before it shows up in browser.
So what to do? Simply change the response content type? Is there any
base64-Type?
regards

While observing the response I noticed just an empty result.
How are you observing the response? Use network sniffer and/or Network
pane from Web Developer Tools in Chrome (Shift+Ctrl+I). Check content and
type of the response ('Content-Type' header).

[Proto-Scripty] Re: AJAX Request: receive base64 encoded image in responseText
Additional info: when I print out the response to console I only receive:
*img src='data:image/jpeg;base64,' width='262'/*
So my base64-encoded string is cutted out. When calling
my reloadurl directly in the browser the image shows up correctly.
Any further suggestions to this?
