问题描述
我是pretty新AngularJS,我想的范围传递给服务,以便我可以根据scope.value执行标签搜索。
I'm pretty new to AngularJS, I want to pass the scope to a service so I can perform a tag search based on the scope.value.
<div data-ng-app="instaSearch" data-ng-controller="search">
<div>
<input type="text" value={{value}} data-ng-model='value'/>
</div>
<p data-ng-hide="value">type a tag</p>
<p data-ng-show="value">...looking for {{value}}</p>
<ul>
<li data-ng-repeat="r in results">
<a>
<img ng-src="{{r.images.thumbnail.url}}" alt="" />
</a>
</li>
</ul>
</div>
下面是JS
var app = angular.module('instaSearch', ['ngResource']);
app.factory('instagram', function($resource){
return {
searchTag: function(callback){
var api = $resource('https://api.instagram.com/v1/tags/:tag/media/recent?client_id=:client_id&callback=JSON_CALLBACK',{
client_id: '3e65f044fc3542149bcb9710c7b9dc6c',
tag:'dog'
},{
fetch:{method:'JSONP'}
});
api.fetch(function(response){
callback(response.data);
});
}
}
});
app.controller('search', function($scope, instagram){
$scope.$watch('value', function(){
$scope.results = [];
instagram.searchTag(function(data){
$scope.results = data;
});
});
});
推荐答案
您可以使用 $ scope.value
访问值。
app.factory('instagram', function ($resource) {
return {
searchTag: function (tag, callback) {
var api = $resource('https://api.instagram.com/v1/tags/:tag/media/recent?client_id=:client_id&callback=JSON_CALLBACK', {
client_id: '3e65f044fc3542149bcb9710c7b9dc6c',
tag: tag
}, {
fetch: {
method: 'JSONP'
}
});
api.fetch(function (response) {
callback(response.data);
});
}
}
});
app.controller('search', function ($scope, instagram) {
$scope.$watch('value', function () {
$scope.results = [];
instagram.searchTag($scope.value, function (data) {
$scope.results = data;
});
});
});
