无法使ng-click="speakOut()"正常工作，它不是在调用speakOut函数，但是ng-click="getCalories()"可以完美地工作。有什么想法我做错了吗？
angular.module('watson', ['ngSanitize'])
.controller('textcntr', function($scope, $http) {
$scope.speakOut = function() {
$scope.text = document.getElementById("speak").value;
$http.get('https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize?username=xxx&password=xxx=Your search term').success(function(data) {
console.log(data);
})
.error(function(data, status) {
console.error('Repos error', status, data);
})
}
