angularstrap typeahead 处理异步数据
郑帅
使用 angularstrap typeahead 的时候下拉列表总是比输入的数据慢一步，注意下你的代码

<body ng-app="app">
<div ng-controller="firstCtrl">
<div class="form-group">
<label><i class="fa fa-home"></i> Address <small>(async via maps.googleapis.com)</small>
</label>
<input type="text" class="form-control" ng-model="selectedAddress" data-animation="am-flip-x" ng-options="address.formatted_address as address.formatted_address for address in getAddress($viewValue)" placeholder="Enter address" bs-typeahead>
</div>
</div>
</body>var app = angular.module('app', ['mgcrea.ngStrap']);
app.controller('firstCtrl', function($scope, $http) {
$scope.getAddress = function(viewValue) {
var params = {
address: viewValue,
sensor: false
};
return $http.get('http://maps.googleapis.com/maps/api/geocode/json', {
params: params
})
.then(function(res) {
return res.data.results;
});
};
});
需要注意数据源使用
getAddress($viewValue)
处理请求使用
then
监听选中列表的事件，加在你自己的控制器里即可
$scope.$on('$typeahead.select', function(value, index) {
console.log(value);
console.log(index);
