我使用Select2作为预先控制。当用户输入搜索词时,下面的代码非常有效。
但是,在将数据加载到页面时,我需要能够手动设置搜索框的值。
理想情况如下:$ scope.selectedProducerId = {id:1,text:" Existing producer}
但是,由于未检索到任何数据,因此Select2数据源为空。
所以我真正需要做的是向数据源添加一个新的数据数组,然后设置$ scope.selectedProducerId,如:$ scope.producersLookupsSelectOptions.addNewData({id:1,text: "现有生产者})然后 $ scope.selectedProducerId = 1;
研究这个我已经看到了使用initSelection()的各种建议,但是我无法看到如何使其工作。
我还试图设置createSearchChoice(term),但该术语没有出现在输入框中。
如果有任何帮助,我将非常感激。
由于
这是html
<div class="col-sm-4">
<input type="text" ui-select2="producersLookupsSelectOptions" ng- model="selectedProducerId" class="form-control" placeholder="[Produtor]" ng-change="selectedProducerIdChanged()"/>
</div>
这是控制器
angular.module("home").controller("TestLookupsCtrl", [
"$scope", "$routeParams", "AddressBookService",
function($scope, $routeParams, AddressBookService) {
$scope.producersLookupsSelectOptions = AddressBookService.producersLookupsSelectOptions();
}
]);
这是服务:
angular.module("addressBook").service("AddressBookService", [
"$http", "$q", function($http, $q) {
var routePrefix = "/api/apiAddressBook/";
//var fetchProducers = function(queryParams) {
// return $http.get(routePrefix + "GetClientsLookup/" + queryParams.data.query).then(queryParams.success);
//};
var _getSelectLookupOptions = function(url, minimumInputLength, idField, textField) {
var _dataSource = [];
var _queryParams;
return {
allowClear: true,
minimumInputLength: minimumInputLength || 3,
ajax: {
data: function(term, page) {
return {
query: term
};
},
quietMillis: 500,
transport: function(queryParams) {
_queryParams = queryParams;
return $http.get(url + queryParams.data.query).success(queryParams.success);
},
results: function(data, page) {
var firstItem = data[0];
if (firstItem) {
if (!firstItem[idField]) {
throw "[id] " + idField + " does not exist in datasource";
}
if (!firstItem[textField]) {
throw "[text] " + textField + " field does not exist in datasource";
}
}
var arr = [];
_.each(data, function(returnedData) {
arr.push({
id: returnedData[idField],
text: returnedData[textField],
data: returnedData
});
});
_dataSource = arr;
return { results: arr };
}
},
dataSource: function() {
return _dataSource;
},
getText: function (id) {
if (_dataSource.length === 0) {
throw ("AddressBookService.getText(): Since the control was not automatically loaded the dataSource has no content");
}
return _.find(_dataSource, { id: id }).text;
}
//initSelection: function(element, callback) {
// callback($(element).data('$ngModelController').$modelValue);
//},
//createSearchChoice:function(term) {
// return term;
//},
addNewData:function(data) {
this.ajax.results(data,1);
};
};
return {
producersLookupsSelectOptions: function() {
var url = routePrefix + "GetClientsLookup/";
return _getSelectLookupOptions(url, 2, "Id", "Name");
},
}
}
]);
