javascript - AngularJS directive runtime template change -


i have been trying make input directive, allows different input types (eg interval (min-max), datetime, number, text...). important whenever user changes type of data, corresponding input changes template. need able have more 1 input on page (see plunkr better understand).

after lot of trial , error, , research, have come conclusion need watch attribute (great-input), replace template of input, according value selected input type, , compile it. not able in compile function, , watches not working in link function (i getting t1,t2).

so, need is, on change of value in select(type), change template of input (for simplicity, have color coded different input types).

$scope.$watch('greatinput', function (newval) {      console.log(newval);      html = gettemplate(newval);      $elem.html('').append($compile(html)($scope)); });

this pretty function should work (with changes, according implemented), cant find right place it.

complete code on: http://plnkr.co/edit/bcuiqg?p=preview

by far easiest approach use ng-ifs in directive template , bind type of input on scope:

.directive("greatinput", function(){   return {     template: '<input ng-if="isstr()" type="txt"    ng-model="greatinputmodel">\                <input ng-if="isint()" type="number" ng-model="greatinputmodel">\                <input ng-if="isdbl()" type="number" ng-model="greatinputmodel">',     scope: {       greatinputmodel: "=",       greatinputtype: "@",       // etc...     },     link: function($scope){        $scope.isstr = function(){           return $scope.greatinputtype === "5" || someothercondition();        }        // same $scope.isint , $scope.isdbl     }   } });
