Is there a script to create a button to set an activated frame to document size + bleed?

Here is a script that creates a script that creates a button that sets an activated frame to document size + bleed.

Why do you need a script to create a button that sets an activated frame to document size + bleed? You might as well have a script that sets an activated frame to document size + bleed, because you already need to double-click the script that sets an activated frame to document size + bleed and so there is no need to show another button that you can click to set an activated frame to document size + bleed in that.

theScript = 'var w = new Window("dialog", "Reframe");\n'+
'w.b = w.add("button", undefined, "Click me!");\n'+
'w.b.onClick = function(){ w.close(3); };\n'+
'if (w.show() == 3)\n'+
'{\n'+
'dp = app.activeDocument.documentPreferences;\n'+
'app.selection[0].geometricBounds = [\n'+
'app.layoutWindows[0].activePage.bounds[0]-dp.documentBleedTopOffset,\n'+
'app.layoutWindows[0].activePage.bounds[1]-dp.documentBleedBottomOffset,\n'+
'app.layoutWindows[0].activePage.bounds[2]+dp.documentBleedInsideOrLeftOffset,\n'+
'app.layoutWindows[0].activePage.bounds[3]+dp.documentBleedOutsideOrRightOffset];\n'+
'}';
writeFile = new File (app.activeScript.parent+'/new script.jsx');
writeFile = writeFile.saveDlg( 'Save script', File.fs == "Windows" ? "Script:*.jsx,All files:*.*" : function(file) { return file instanceof Folder || (!(file.hidden) && file.name.match(/\.jsx$/i)); } );
if (writeFile != null && writeFile.open("w"))
{
  writeFile.encoding = "utf8";
  writeFile.write (theScript);
  writeFile.close();
}

Yeah, that's what I figured This is the bare essentialness of what it does:

dp = app.activeDocument.documentPreferences;
app.selection[0].geometricBounds = [
app.layoutWindows[0].activePage.bounds[0]-dp.documentBleedTopOffset,
app.layoutWindows[0].activePage.bounds[1]-dp.documentBleedBottomOffset,
app.layoutWindows[0].activePage.bounds[2]+dp.documentBleedInsideOrLeftOffset,
app.layoutWindows[0].activePage.bounds[3]+dp.documentBleedOutsideOrRightOffset];
