我在指令中嵌套了select2输入,我想将所选值绑定到外部作用域。我怎样才能做到这一点。 plunker exampleui-select2内部指令绑定到外部作用域
指令代码:
app.directive('optionChoices', function() {
return {
restrict: 'EA',
scope: {
type: '=',
selections: '='
},
template: '<input ng-if="type === 1" ui-select2="textChoices" ' +
'ng-model="selections" style="width:200px" />' +
'<input ng-if="type === 2" ui-select2="colorChoices" ' +
'ng-model="selections" style="width:200px" />' +
'{{\'inner:\' + selections}}',
link: function (scope, element, attrs) {
function Query(query) {
var data={
results:[]
};
if (query.term.length > 0) {
data.results.push({id:query.term,text:query.term});
}
query.callback(data);
}
scope.textChoices = {
query: Query,
tags: [],
initSelection: function() {}
};
scope.colorChoises = angular.extend({}, scope.textChoices, {
formatSelection: function(state) {
if (!state.id) return state.text;
return "<div style='background-color:yellow;'> </div>" + state.text;
}
});
}
};
});
