javascript - jQuery $(this) does not insert text into my element -


i adding flagging functionality project of mine, , can't jquery's $(this) selector work.

the goal of change text in div flag flagged when user clicks it, , ajax query runs successfully. html/php is:

<div class="flag" post_to_flag='".$post_to_flag."'>flag</div>

and javascript deals div is:

$('.flag').live('click', function () {     $.post('../php/core.inc.php', {         action: 'flag',         post_to_flag: $(this).attr('post_to_flag')     }, function (flag_return) {         if (flag_return == 'query_success') {             $(this).text('flagged');         } else {             alert(flag_return);         }     }); });

i can't replace text flagged, if replace this selector .flag selector, replace class of flag on page.

i have checked, , $(this) selector getting attribute of 'post_to_flag' fine. why happening, , how can fix it?

you should add context variable:

$('.flag').live('click', function () {     var $context = $(this);     $.post('../php/core.inc.php', {         action: 'flag',         post_to_flag: $context.attr('post_to_flag')     }, function (flag_return) {         if (flag_return == 'query_success') {             $context.text('flagged');         } else {             alert(flag_return);         }     }); });

you calling multiple functions within jquery selection call. when go $.post() function, scope changes. this refers different scope when inside one().

@moak's suggestion, if set variable jquery object, it's best denote variable beginning $ potential clarity future readers or yourself.

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...
