Hi I am new to Angularjs. I am trying to create a typeahead where I am fetching the data through the api. I tried searching for the solution but I dint get the solution what I was looking for. Below is the code what I have done so far. HTML CODE:
<div ng-controller="newController">
<div class="selection-box">
<div class="title-box">
<div class="search_item">
<input name="document" ng-model='query' type="text" typeahead="document as document.name for document in documents | filter:query | limitTo:8" id='document' placeholder="SEARCH FOR YOUR DOCUMENT" class="search_box">
</div>
{{query}}
</div>
</div>
</div>
In this input box whatever I type it gets printed in the {{query}} but doesn't show any data fetching from the api. I am using bootstrap ui . Below is the controller what I wrote.
newController.js:
var myApp = angular.module('myModule', ['ui.bootstrap']);
myApp.service("searchService", function ($http) {
var apiUrl = "http://12.56.677/api/v1/mobile/";
var apiKey = "123nm";
this.searchDocument = function(query) {
var response = $http({
method: 'post',
url: apiUrl + "search",
headers: {'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'},
params: {
key: apiKey,
query: query
}
});
return response;
};
});
myApp.controller('newController', ['$scope', 'searchService' , function($scope, searchService, $rootScope, $http, $window, $document) {
var apiUrl = "http://12.56.677/api/v1/mobile/";
var apiKey = "123nm";
url = apiUrl + "search";
Key = apiKey;
$scope.query = undefined;
console.log(query);
searchService.searchDocument(query='').then (function (res) {
if(res.data.status == "OK")
{
$scope.documents = res.data.result;
console.log($scope.documents);
// var userinformation = res.data.result;
// $window.localStorageService.setItem('searchDocument', JSON.stringify(query));
}
else {
$scope.errorMessage = res.data.message;
}
})
}])
Any help would be appreciated.
//HTML
<input name="document"
ng-model='query' type="text"
uib-typeahead="document as document.name
for document in documents |filter:query | limitTo:8" id='document'
placeholder="SEARCH FOR YOUR DOCUMENT" class="search_box">
//Controller
searchService.searchDocument('').then (function (res) {
if(res.data.status == "OK"){
$scope.documents = res.data.result;
}
else {
$scope.errorMessage = res.data.message;
}
});
What you attempted to do is using typeahead with a pre-fetched list (an with an empty query).
You probably want to do asynchronous search and would need a data fetch function to do so.
HTML, note the typeahead expression:
<input name="document" ng-model='query' type="text"
typeahead="document as document.name for document in (getDocuments() | limitTo:8)"
id='document'
placeholder="SEARCH FOR YOUR DOCUMENT" class="search_box">
Controller:
myApp.controller('newController', ['$scope', 'searchService' , function($scope, searchService, $rootScope, $http, $window, $document) {
var apiUrl = "http://12.56.677/api/v1/mobile/";
var apiKey = "123nm";
// What are these two undeclared variables lying here around for?
url = apiUrl + "search";
Key = apiKey;
$scope.getDocuments = function(query){
searchService.searchDocument(query) // Check your API, I am not sure how you're API treats these parameters
.then (function (res) {
if(res.data.status == "OK")
{
var documents = res.data.result;
console.log(documents);
return documents;
}
else {
$scope.errorMessage = res.data.message;
return [];
}
})
}
}])
我认为您需要从searchService.searchDocment()返回承诺,如下所示:
return searchService.searchDocument(query='').then(......)
