javascript - Render HTML without the extra "data-reactid" DOM attribute in React.js? -


so, i'm doing in 1 of react.js files:

 render: function() {      var stuff = this.props.stuff;      function gethtmlforkey(key_name, title) {         var key_name = key_name.tolowercase();             return object.keys(thing).filter(function(key) {                 return key && key.tolowercase().indexof(key_name) === 0;             }).map(function(key, index) {                 var group_title = index === 0 ? title : '';                 if(profile[key] != null && thing[key] != "") {                     return (                         <span>                         {group_title ? (                             <li classname="example-group-class">{group_title}</li>                         ) : null }                         <li key={key} classname="example-class">                             {thing[key]}                         </li>                         </span>                     );                 }                 }, this);     }      /** grouping keyword **/     var group1 = gethtmlforkey('stuff1', 'group title 1');      /** return facecards **/     if (stuff) {         return (             <div classname="col-md-6">                 <div classname="media">                     <div classname="pull-left">                         <a href="#" onclick={this.open}>                             <img src={this.props.stuff} classname="media" />                         </a>                     </div>                     <div classname="top">                         {group1}                     </div>        } }

when renders outputs like:

  <li class="example-group-title" data-reactid=".0.0.2.0.$2083428221.0.1.0:0.0">group title</li>

in other react.js file, i've got:

    var stuffapp = require('./components/stuffapp.react');      reactdom.render(     <stuffapp />,      document.getelementbyid('main-content')     );

how render html doesn't include dom attribute markup (that is, data-reactid)? want try , save bits, ya know? i've been reading related https://facebook.github.io/react/docs/top-level-api.html reactdomserver, wondering if there easier way? if not, how integrate that?

the method you're looking reactdom.rendertostaticmarkup.

from docs:

similar rendertostring, except doesn't create dom attributes such data-react-id, react uses internally. useful if want use react simple static page generator, stripping away attributes can save lots of bytes.

this makes difference if you're rendering on server. also, markup won't compatible react, it's useful display components.

however, statement made confuses me:

how render html doesn't include dom attribute markup (that is, data-reactid)? want try , save bits, ya know?

if you're trying save bits, don't on client (which react runs), on server transfer fewer bits down client. once app running on client's browser, don't need worry memory dom attributes take (which literally bits you'd saving).

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
