I tried turning on AlertOnError, and nothing seems to appear in Firebug,
or elsewhere.
Here is what I trying to run:
CmdUtils.getURLSnapshot = function getURLSnapshot(url, options){
var win = CmdUtils.getHiddenWindow();
win.document.location.href = url;
win.document.addEventListener("load", function(){
return CmdUtils.getWindowSnapshot(win, options);
}, true);
}
CmdUtils.CreateCommand({
name: "back",
description: "Browser's Back Function",
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)
}
});
Everything works except that upper part, and have really no idea where
the problem is.
