JQuery doesn't validate numbers larger than 9999 -


this weird.

the morgage calculator working on (i had question previous one) working way wanted except.... doesn't validate values greater 9999.

if go link below, you'll able see mean.

http://jsfiddle.net/flt8c/1/

the code supposed make sure values entered in down payment , purchase price numbers. if they're not, message comes up, if are, code validates purchase price not greater down payment amount.

the code works... if values enter 9999 or lower. if do, example... 1350000 , 5000 down payment, code doesn't submit. if 9999 , 5000, no problem.

i'm confused. ideas?

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...
