javascript - binding data in angularJS -


so have simple controller in app.js 

var app = angular.module('graphplotterdemoapp', []);  app.controller('plotctrl1', function ($scope) {     $scope.data = [{         x: [1, 2, 3, 4],         y: [10, 15, 12, 17]}]; });

and trying bind table ...

<!doctype html> <html> <head lang="en">     <script src="angular.min.js"></script>     <script src="app.js"></script> </head> <body ng-app="graphplotterdemoapp">  before div = plotctrl1 <div  ng-controller="plotctrl1">     {{data}}     <table>     <thead><tr><td>x</td><td>y</td></tr></thead>     <tbody ng-repeat='x1 in data[0].x'>         <tr>             <td><input type='number' ng-model='x1'></td>             <td><input type='number' ng-model='data[0].y[$index]'></td>         </tr>         </tbody>     </table> </div>      </body> </html>

it turns out there two-way data binding ng-model='data[0].y[$index] not ng-model='x1' !

anyone knows reason this??

check out page in wiki. https://github.com/angular/angular.js/wiki/understanding-scopes#ng-repeat

it's understanding difference between objects , primitives when using angular scoping.

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). ...
