각도 정보에서 일부 데이터를 브로드 캐스팅하려고합니다. 지시문. cannot read property $broadcast of undefined 오류가 발생합니다. 내 지침에서 컨트롤러에 데이터를 브로드 캐스트하려는 방식에 문제가 있습니까? 내 컨트롤러에서
angular.module('myapp').directive("fileread", function (ServerRequest, $sessionStorage, $rootScope) {
return {
scope: {
myData: '=',
opts: '='
},
link: function ($scope, $elm, $attrs, $rootScope) {
console.log($scope)
console.log('fileread before',$scope.myData,$scope.opts)
$elm.on('change', function (changeEvent) {
console.log('directive');
var reader = new FileReader();
console.log(reader)
reader.onload =function (evt) {
$scope.$apply(function() {
var data = evt.target.result;
console.log('fileread scope apply')
var workbook = XLSX.read(data, {type: 'binary'});
------------PROBLEM IS BELOW HERE-------------
$scope.broadcastfilename = data;
$rootScope.$broadcast('filenameforupload', '$scope.broadcastfilename');
console.log('passed broadcast');
-------------AND ABOVE HERE--------------------
var headerNames = XLSX.utils.sheet_to_json(
workbook.Sheets[workbook.SheetNames[0]],
{ header: 1 }
)[0];
var importedData = XLSX.utils.sheet_to_json(workbook.Sheets[workbook.SheetNames[0]]);
console.log(headerNames,workbook);
console.log(importedData)
$sessionStorage.headerNames = headerNames;
$sessionStorage.importedData = importedData;
// addRows(data);
$elm.val(null);
//this is where we add the new data to the existing data
var query = {
patients: importedData,
coverKey: $sessionStorage.practiceLogged.coverKey
}
});
};
reader.readAsBinaryString(changeEvent.target.files[0]);
});
}
}
});
나는이 :
$scope.$on('filenameforupload', function(event, args) {
console.log(args, "<------------");
});
