【问题描述】:
我正在从 AngularJS 调用 restful 服务。 HTML 非常基础,带有一个输入文本框和一个用于查询的按钮。
//basic.html
<!DOCTYPE html>
<html ng-app="cgApp" >
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular-resource.js"></script>
<script src="../js/controller.js"></script>
<script src="../js/service.js"></script>
</head>
<body>
<div ng-controller="CgseqCtrl">
<input ng-model="analysisid"><button ng-click="searchById()">Search</button>
<table>
<tr>
<td>{{seq.analysisId}}</td>
<td>{{seq.center}}</td>
<td>{{seq.diseaseAbbr}}</td>
<td>{{seq.filepath}}</td>
<td>{{seq.library}}</td>
</tr>
</table>
</div>
</body>
</html>
我使用服务调用rest api
// service.js
app.factory("Cgseq", function ($http) {
// return $resource('http://localhost:8080/cgweb/api/seqs/fdebfd6e-d046-4192-8b97-ac9f65dc2009');
var service = {};
service.getSeqById = function(analysisid) {
return http.get('http://localhost:8080/cgweb/api/seqs/' + analysisid);
}
service.getSeq = function() {
return $http.get('http://localhost:8080/cgweb/api/seqs/fdebfd6e-d046-4192-8b97-ac9f65dc2009');
}
return service;
});
一旦点击按钮,函数searchById()就会被执行。它在我的控制器中实现。
// controller.js
var app = angular.module('cgApp', [])
app.controller('CgseqCtrl', ['$scope', 'Cgseq', function($scope, Cgseq){
$scope.searchById() = function() {
CgSeq.getSeqById($scope.analysisid)
.then(function(response){
$scope.seq = response;
});
}
}]);
当我在浏览器中加载 basic.html 时,甚至在我在输入框中输入内容并单击按钮之前,我收到以下错误:
angular.js:12416 TypeError: $scope.searchById is not a function
at new <anonymous> (controller.js:8)
【问题讨论】:
-
您尝试使用 $scope.searchById = function() {....} 希望这能解决您的问题。
