Angular Material 使用 $http 调用自动完成
Angular Material autocomplete with $http call
我正在尝试做的是 Angular Material 自动完成 (md-autocomplete)，其中的数据是从对我的 REST API 的 AJAX 调用动态检索的。不幸的是，我只得到不确定的进度条，而不是自动完成项目，如下所示。
结果
控制器
$scope.customersSelect = {};
$scope.selectedItem = null;
$scope.searchText = null;
$scope.getCustomers = function (query) {
selectsService.getCustomers(query).then(function (results) {
$scope.customersSelect = results.data;
console.log($scope.customersSelect);
}, function(error) {
alert(error.data.message);
});
}
服务
var selectsServiceFactory = {};
_getCustomers = function (query) {
return $http.get(serviceBase + 'api/selects/customers/' + query)
.then(function(results) {
return results;
});
}
selectsServiceFactory.getCustomers = _getCustomers;
return selectsServiceFactory;
查看
<md-autocomplete md-floating-label="Klient"
autocomplete="off"
flex=""
md-search-text-change="getCustomers(searchText)"
md-item-text="item"
md-items="item in customersSelect"
md-search-text="searchText"
md-selected-item="machine.customerId"
md-input-maxlength="100"
md-input-minlength="2"
md-input-name="machineOwner">
<md-item-template>
<span md-highlight-text="searchText">{{item}}</span>
</md-item-template>
我正在从 API 成功获取数据，因为我可以在控制台中看到它打印出来。
使用 $apply 自己启动摘要循环，它会更新视图。
$scope.getCustomers = function (query) {
selectsService.getCustomers(query).then(function (results) {
$scope.customersSelect = results.data;
$scope.$apply();
console.log($scope.customersSelect);
}, function(error) {
alert(error.data.message);
});
}
(function() {
'use strict';
angular
.module('MyApp')
.controller('DemoCtrl', DemoCtrl);
function DemoCtrl($http) {
var self = this;
self.data = null;
self.selectedItem = null;
self.searchText = null;
self.querySearch = function (query) {
$http.get('http://www.omdbapi.com/?s=' + escape(query))
.then(function(result) {
self.data = result.data.Search;
return result.data.Search;
});
}
}
})();

我终于做到了。这是解决方案。
我也为此苦苦挣扎。我最终做了这样的事情：
$scope.querySearch=function(searchTerm) {
return $http({
url:"http://mysearch.api?keyword="+searchTerm,
method:"GET"
})
.then(function(res) {
return res.data;
}
}
我的问题是 md-autocomplete 需要结果是一个数组，而 $http 的响应是一个对象。我希望这对其他人有帮助！！
您可以使用 Angularjs promises 从 $http 调用中获取数据。
