javascript - Why jQuery intermittently fails to detect click? -

-

why jquery detect click , not?

i have #options element when clicked #dropdown-menu shown. when user clicks anywhere outside #dropdown-menu (except on #options element) dropdown hidden. here code of time works , doesn't:

jquery( document ).ready( function() {      jquery('#options').click( function(){         jquery('#dropdown-menu').slidedown();     });      jquery(document).click( function(event) {          if( !jquery(event.target).closest('#dropdown-menu').length && !jquery(event.target).is('#options') ) {              if(jquery('#dropdown-menu').is(":visible")) {                 jquery('#dropdown-menu').hide();             }         }     }); });

i can't figure out why works intermittently. hard accept code works sometimes. noticed event.target comes empty string somtimes... bug jquery?

here fiddle , error can't reproduced.

ok, figured out solution problem. warning: silly , strange!

the problem content of #options, using icon fontawesome represent 'options' so:

<div id="options"><i class="fa fa-ellipsis-v"></i></div>

i removed <i class="fa fa-ellipsis-v"></i> content , added using css, works without fail. not sure why does; guess jquery getting confused when clicked on <i> tag though belogs #options.

css code add fontawesome icon:

#options:before {     content: "\f142";     font-family: fontawesome; }

(thanks everyone's input me pin down problem. appreciate it!)

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
