angularjs - Reusable Button Directive -

-

i got 2 buttons different functions , name, classes same. can create directive buttons?

<div class="sub l">     <button class="b week" ng-click='manageday(cadd, csub = csub + 7)' ng-model="csub" ng-init='csub=0'>substract week/button> </div>  <div class="sub l">     <button class="b day" ng-click='manageday(cadd, csub = csub + 1)' ng-model="csub" ng-init='csub=0'>substract day</button> </div>

how can create button directive out of this? as:

<div substract-button></div> 

var app = angular.module('testapp', [ ]);        app.directive('telsavebutton', function() {      return{          restrict: 'e',  		           template: '<button type="submit" ng-click="onformsubmit()" >directive button</button>',          transclude: true,          scope: {              onsubmit: '&',   			onformsubmit: '&' 			           },          link: function(scope, element, attributes){              scope.submit = function(){                  scope.onsubmit();              }          }      }  });         app.controller('testcntler', ['$scope', '$location',  function ($scope, $location) {    $scope.testcontroller=function()    {  	   alert("working")    }        }]);    
<script data-require="angular.js@~1.3.15" data-semver="1.3.15" src="https://code.angularjs.org/1.3.15/angular.js"></script>  <body class="hold-transition skin-blue sidebar-mini" data-ng-app="testapp"  >     <form novalidate="novalidate" ng-submit="vm.onsubmit()"  ng-controller="testcntler" >        <table width="293" border="0">    <tr>      <td width="127">first name</td>      <td width="150"> <input type="text"  ng-model="fname" ></td>    </tr>    <tr>      <td>mid name</td>      <td> <input type="text"  ng-model="mname" ></td>    </tr>    <tr>      <td>last name</td>      <td> <input type="text"  ng-model="lname" ></td>    </tr>        <tr>      <td colspan="2"> <button type="submit" ng-click="testcontroller()" >static button</button>       <tel-savebutton check-id="firstname" on-form-submit="testcontroller()"></tel-savebutton></td></td>     </tr>      </table>                        </form>    </body>

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

algorithm - Testing tetrahedron-triangle intersection -

-
i want determine whether given triangle intersects tetrahedron. not want compute solution polygon(if exists) itself. there library/package/published practical algorithm can used solve problem directly (unlike attempt below)? i think last resort have use standard polygon-polygon intersection algorithm implementations solve problem indirectly . my attempt on problem: thought of breaking problem of polygon-polygon intersection. each triangular face(say t1 ) of tetrahedron , given triangle t2 , thought of doing following: compute intersection(a line) between planes corresponding each triangle, l1 . for each triangle: for each edge of triangle l2 , compute point of intersection p between l1 , l2 . test(maybe using parametric form) of l2 , if point lies on edge l2 . if both triangles t1 , t2 , there exists at least one edge on intersection point p lies, implies triangles(and hence given tetrahedron , triangle t2 ) do intersect. create orthonormal fr
