I ended up using CmdUtils.log() to see what's going on. I also used this
for some introspection:
function dir(ob){
var a=[],attr
for(attr in ob){a.push(attr)}
return a.sort().join('\n')
}
Very similar to the Pythonic dir().
Here is a slightly more functional version of the previous, the scale of
the thumbnail is way off though...
CmdUtils.getURLSnapshot = function getURLSnapshot(url, options){
var hiddenWindow = CmdUtils.getHiddenWindow();
hiddenWindow.document.location.href = url
return CmdUtils.getWindowSnapshot(hiddenWindow.document.defaultView,
options);
}
CmdUtils.CreateCommand({
name: "back",
description: "Go one step back in history",
takes: {"input": noun_arb_text},
preview: function( pblock, input ) {
var imgData = CmdUtils.getURLSnapshot( "http://mozilla.org";,
{width:500} );
pblock.innerHTML = "Changes to <b style=\"color:yellow\">%s</b>
document.".replace(/%s/, "url");
pblock.innerHTML += "<br/><img src='%s'>".replace(/%s/, imgData );
},
execute: function(input) {
CmdUtils.getWindow().history.go(-1)
}
});
