java - Javascript on (before and after) every Ajax-call -


since i'm working tinymce (please don't go "primefaces has editor" or similar) need execute small piece of javascript before , after every ajax-call. i'd prefer not edit every ajax-call since there lot (and doing bad practice future maintenance).

what elegant solution execute javascript pre- , post- ajax-call on page?

note: i'm using custom composite tinymce-textarea. events object suffice. though keep in mind actual ajax-trigger might invoked totally different object (though nevertheless rerender composite).

use jsf.ajax.addonevent handler.

jsf.ajax.addonevent(function(data) {     switch(data.status) {         case "begin":             // invoked right before ajax request sent.             break;          case "complete":             // invoked right after ajax response returned.             break;          case "success":             // invoked right after successful processing of ajax response , update of html dom.             // in case you're interested in error handling, use jsf.ajax.addonerror handler.             break;     } });

just put in js file included <h:outputscript target="head"> in <h:body> of desired pages. ensure it's loaded after jsf's own jsf.js containing jsf namespace.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
