好的,第一个问题是......好心..
我正在使用Angular的Material框架进行Angular Autofill输入。
我需要用来自ajax调用的数据填充它。 (即一个国家arrey) 我最初的方法是将模块注入应用程序的控制器中,然后当ajax调用返回成功时,我只需启动它的功能。
这不能很好地工作,因为它会在数据恢复之前加载一次(从注入开始)并在检查时崩溃。
拿两个:添加对空数据的检查导致它按预期加载和停止,然后当数据到达时(最终)模块在单个项目中切割它们并准备就绪但页面不能正常工作。由于不工作,我的意思是它不会自动建议你输入..
我认为我需要加载模块而不是其中的函数但我似乎无法做到这一点..这就是我需要帮助的地方..
添加代码:
angular.module("Myapp", ['ngMaterial', 'Autofill-country' ])
.controller("mycontroller", ["$scope", "$http", function ($scope, $http) {
//automatic suggest
automaticsuggest ()
function automaticsuggest() {
suggesturl = 'http://www.mysuggest_front_services'
$http({
method: 'GET',
url: suggesturl,
responseType: "json",
async: false // Just tried that to see if it works.. I am not really fond of it
}).then(function (response) {
countriesarrey = response.data.Countries
// .run('Autofill-country', ['Autofill-country']) - Tried this too..
country(); // this is the function of the autosuggest.
Once checked with breakpoints it does get the array and cut it and filter it etc, but the n when you input something in the input field.. It doesnt suggest..
});
}
自动完成模块
angular.module('Autofill-country', ['ngMaterial', 'ngMessages', 'material.svgAssetsCache'])
.controller('country', country);
function country($timeout, $q) {
var self = this;
if (countriesarrey == "undefined" || countriesarrey == null) { }
else { countrys(); }
// list of `country` value/display objects
function countrys() {
self.countries = loadAll();
self.selectedItem = null;
self.searchTextcountry = null;
self.querySearch = querySearch;
// ******************************
// Internal methods
// ******************************
/**
* Search for countries... use $timeout to simulate
* remote dataservice call.
*/
function querySearch(query) {
var results = query ? self.countries.filter(createFilterFor(query)) : [];
return results;
}
/**
* Build `countries` list of key/value pairs
*/
function loadAll() {
var allcountries = countriesarrey;
console.log(countriesarrey);
return allcountries.split(/, +/g).map(function (country) {
return {
value: country.toLowerCase(),
display: country
};
});
}
/**
* Create filter function for a query string
*/
function createFilterFor(query) {
var lowercaseQuery = angular.lowercase(query);
return function filterFn(country) {
return (country.value.indexOf(lowercaseQuery) === 0);
};
}
}
}

您应该创建一些工厂来获取您的数据,这将有一个方法,返回承诺。在承诺解决后,您可以使用获取的数据执行所需的操作。
var myApp = angular.module('myApp', []);
myApp.factory('myFactory', function($http, $q, $timeout) {
return {
getData: function() {
// return $http.get(...);
},
};
});
myApp.controller('MyCtrl', function(myFactory) {
this.getData = function() {
myFactory.getData().then(function(response) {
// use response.data here
})
}
})
