javascript - Specifying a prop to be a specific Component in React -


i'm writing component, , wan't 1 of props alway instances of spesific component

class component extends react.component {     static proptypes: {         children: /*only childcomponents allowed*/     } }  class childcomponent extends react.component {} 
<component><div /></component> // should fail <component><div /><childcomponent></component> // should fail <component><childcomponent /></component> // should succedd <component><childcomponent /><childcomponent /></component> // should succedd 

    children: react.proptypes.instanceof(childcomponent)

look here - https://facebook.github.io/react/docs/reusable-components.html.

update instanceof not working in case, try alternate approach -

in proptypes, allow node -

children: react.proptypes.node

then in render method -

react.children.map(children, (child, index) => {   if (!react.isvalidelement(child)         || !child.type         || child.type.displayname !== 'childcomponent'){     // exterminate! exterminate!   } }

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). ...
