Does anyone know anything about source codes?
When using the Japanese website goo for lyrics, they block the right click and copy functions...
I guessed there must be a workaround in finding some link in the source code to get to the lyrics through another way.
So when looking at the source code I found that the text in question should be located around here:
<script type="text/javascript">
var cn;
function xcanvas(uu, canvasNodes) {
cn= canvasNodes;
var s = document.createElement('script');
s.setAttribute('src', '/sp/lyric/print_json.php?callback=draw&id=w2GQizqDofjNZGwzp9WjjdjXlIrzgN%2FaBgYHflggGDg%3D%3AFFoLLcbgXyhHvpHF%2BsYqK%2B5gb%2BtIwhS9wtcUf3ESBdE%3D');
document.getElementsByTagName('head')[0].appendChild(s);
}
function draw(data){
var y = 20;
document.getElementById('canvas').height = ( ( data.length + 1 ) * y );
var ctx = cn[0].getContext("2d");
ctx.textBaseline = "top";
ctx.font = '15px MS Pゴシック';
var i = 0;
for ( i = 0; i < data.length; i++ ){
ctx.fillText(data[i ], 0, y * i );
}
}
// IE9以上
var msie=navigator.appVersion.toLowerCase();
msie=(msie.indexOf('msie')>-1)?parseInt(msie.replace(/.*msie[ ]/,'').match(/^[0-9]+/)):0;
if(msie>8){
cn= getElementById('canvas');
var s = document.createElement('script');
s.setAttribute('src', '/sp/lyric/print_json.php?callback=draw&id=w2GQizqDofjNZGwzp9WjjdjXlIrzgN%2FaBgYHflggGDg%3D%3AFFoLLcbgXyhHvpHF%2BsYqK%2B5gb%2BtIwhS9wtcUf3ESBdE%3D');
document.getElementsByTagName('head')[0].appendChild(s);
}
</script>
And I tried doing a couple of things with this part of the link:
"/sp/lyric/print_json.php?callback=draw&id=w2GQizqDofjNZGwzp9WjjdjXlIrzgN%2FaBgYHflggGDg%3D%3AFFoLLcbgXyhHvpHF%2BsYqK%2B5gb%2BtIwhS9wtcUf3ESBdE%3D"
But I cannot find it. ^^
Can anyone help me? I want to learn about source codes! xD

That's pretty hardcore for right click blocking, lol.
You get a response with unicode characters:
Translated with an online converter:
\u7d04\u675f\u3082\u3057\u306a\u3044\u306e\u306b => 約束もしないのに
Etc.
In Google Chrome or Safari you can use the javascript console (Ctrl Shift J), Network tab, "print_json.php" entry, Response tab, to see the JSON response. Or use Firebug in Firefox.
EDIT: Ah, travis beat me to it

Cool! Fast response and I learned a lot!
Now let me try and retrace the logic behind this.
A)
The reason to search for the "print_json.php" file is:
My guess: Because that's what it linked to when I found out that the link said:
"/sp/lyric/print_json.php?callback=draw&id=w2GQizqDofjNZGw..."
Or is the "print_json.php" something standard that is always looked for when messing with unclickable things?
B)
The reason to press the "network" tab:
I have no clue xD
C)
The reason to look at response and not at preview:
I guess that preview has limits, but in this case, since it's a small text, it all fits in there.
How's my guessing? xD

You solved most of it in your first post, just not how to see the response. Then print_json is a Javascript callback, so after the HTML page loads, the page calls print_json and writes the results to a 2D canvas. The network tab just logs all the network activity, so everything including images etc will be there. The response is the actual raw response, the preview is a just a preview, but sometimes it pretty prints it and that's useful for JSON data.
