Using jquery-blockui, also disallow tabbing to blocked elements -

-

cross-post github: https://github.com/malsup/blockui/issues/121

link plugin: http://malsup.com/jquery/block/

while elements blocked cannot clicked, it's still possible use tabulator access them, , use enter activate it. possible skip blocked element when tabbing?

for now, stop user tabbing blocked elements, stops user. it'd better if skip blocked ones.

var proxiedblock = $.fn.block; $.fn.block = function () {     var $elem = proxiedblock.apply(this, arguments);      $elem.on('focusin.kj', function (evt) {         evt.preventdefault();          $(evt.relatedtarget).focus();     });      return $elem; };  var proxiedunblock = $.fn.unblock; $.fn.unblock = function () {     var $elem = proxiedunblock.apply(this, arguments);      $elem.off('focusin.kj');      return $elem; };

i had same problem , discussed op here: https://github.com/malsup/blockui/issues/121#issuecomment-129719120 ended going approach allows blocked elements skipped. changed tabindex html attributes of elements blocked. ended being best approach our app didn't have modify blockui code. used tabindex of "-2" because of normal elements blocked had tabindex of -1. example date picker hidden div. didn't want overwrite tabindex of hidden div , possibly confuse 3rd party js. used -2 distinguish between calls , other widgets.

$(this).block(); $(this).find('input,select,a').filter(':not([tabindex=-1])').attr('tabindex',-2);  $(this).unblock(); $(this).find('[tabindex=-2]').removeattr('tabindex');

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
