javascript - Regex to get parameters of Embed -

-

code:

var = [  /<b\>(.*?)<\/b\>/ig,  /<i\>(.*?)<\/i\>/ig,   /<u\>(.*?)<\/u\>/ig,  /<br\/\>(.*?)/ig,  /<embed(.*?)/ig  ];   var b = [    '[b]$1[/b]',    '[i]$1[/i]',    '[u]$1[/u]',    '\r',    '[flash($2,$3)]$1[/flash]'   ];     (var =0;i<a.length;i++) {     ele = ele.replace(a[i], b[i]);      }

html:

<embed   pluginspage="http://www.macromedia.com/go/getflashplayer"  src="http://www.youtube.com/v/dm0vrhuu6ei"  width="500"   height="500"   type="application/x-shockwave-flash"   wmode="transparent"   quality="high"   scale="exactfit">

what is

$1 starting position of [flash]

$2 width parameter

$3 height parameter

the beginning of code change html elements bbcodes. should go regex different in embed regex? see example here better understand!

as turns out - jquery has you're looking for, if know lesser used variants, fact $('<b>hello</b>') parses , returns html you've passed it. you're looking this:

var str = '<b>hello</b><br/><i>world</i><br/><u>i hate you!</u><br/><ul><li>good</li><li>goodbye</li><li>good afternoon</li><li>good marrow</li></ul> <embed pluginspage="http://www.macromedia.com/go/getflashplayer" src="http://www.youtube.com/v/dm0vrhuu6ei" width="500" height="500" type="application/x-shockwave-flash" wmode="transparent" quality="high" scale="exactfit">';  var convertible = {     b: function(loc){         return '[b]' + converttobbcode($(loc).html()) + '[/b]';     }     , i: function(loc){         return '[i]' + converttobbcode($(loc).html()) + '[/i]';     } }; function converttobbcode(str){     if (!str || str == undefined) return '';     var toreturn = '';     $('<div>'+str+'</div>').contents().each(function(){         if (this.tagname == undefined) toreturn += this.nodevalue;         else if (convertible[this.tagname] != undefined)             toreturn += convertible[this.tagname](this);         else              toreturn += $(this).html(converttobbcode(this.innerhtml))[0].outerhtml;     });     return toreturn; }  $('textarea').val(converttobbcode(str));

i haven't done whole thing, because think it's pretty self evident what's being done. hardest part embed, becomes easy pie:

    , embed: function(loc){         var l = $(loc);         return '[flash(' + l.attr('width') + ',' + l.attr('height') + ')]' + l.attr('src') + '[/flash]';     }

you can see partial solution here, in jsfiddle.

remember, should using regular expressions parse context sensitive language html. should listen when people tell you're approaching problem wrong - if have valid reason non-traditional approach, should spell out think traditional approach fails.

plot - Remove Objects from Legend When You Have Also Used Fit, Matlab -

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution: ...

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
