[英]Issue with angularjs typeahead and async api call
I've the following implementation, html: 我有以下实现,html:
<input id="myField" name="myField" class="form-control" type="text" placeholder="myField"
ng-model="myController.myObj.FieldValue" typeahead-editable="false"
uib-typeahead="item as item.Description for item in myController.fieldDS($viewValue)" required>
controller: 控制器:
var vm = this;
vm.fieldDS = myService.getFieldDS;
service: 服务:
function getFieldDS() {
return [{'Description': 'ItemA'}, {'Description': 'ItemB'}, {'Description': 'ItemC'}];
}
And it works fine. 而且效果很好。 The issue starts when I'm trying to invoke remote async api.
当我尝试调用远程异步api时,问题开始。 I changed service using ngResource and I tried with following functions:
我使用ngResource更改了服务,并尝试了以下功能:
function getFieldDS() {
return Resource.query();
}
function getFieldDS() {
var items = Resource.query();
return items.$promise;
}
function getFieldDS() {
var items = Resource.query();
items.$promise.then(
function (result, responseHeaders) {
return result;
},
function (httpResponse) { console.log('failed: ' + httpResponse); }
);
}
or with code on controller: 或使用控制器上的代码:
vm.fieldDS = myService.getFieldDS;
vm.fieldDS = function () {return myService.getFieldDS();};
myService.getFieldDS().then(function (result) { vm.fieldDS = result;})
in last case I receive typeerror about function expected, maybe typeahead not found binding source!? 在最后一种情况下,我收到有关预期功能的typeerror,可能找不到绑定源!
In all other case, when I insert a character on input field, page load, api has been called, but nothing is showed on input list. 在所有其他情况下,当我在输入字段中插入字符时,页面加载,api已被调用,但输入列表中未显示任何内容。 If I try a console.log with response from query or from service, array has been obtained properly.
如果我尝试通过console.log从查询或服务获得响应,则已正确获取数组。 It seems that controller or typeahead input field doesn't wait response from api, but I don't understand how to solve this issue.
似乎控制器或预输入字段不会等待api响应,但我不知道如何解决此问题。 Please may you help me?
请你帮我一下 Thanks a lot
非常感谢
edit: service method: 编辑:服务方法:
function getFieldDS() {
var items = Resource.query();
return items.$promise;
}
and controller: 和控制器:
function getSomething() {
var temp = myService.getFieldDS();
temp.then(
function(result) {
console.log(result);
return result;
}
);
return temp;
}
vm.fieldDS = getSomething;
prints on console the proper array with all objects, but they aren't add on typeahead field. 在控制台上打印包含所有对象的正确数组,但不会在typeahead字段上添加它们。 I found some example code with same implementation, but I don't understand why in my case it doesn't work.
我发现一些示例代码具有相同的实现,但是我不明白为什么在我的情况下它不起作用。
Issue Solved! 问题已解决! The issue is related to conflict with block-ui module.
该问题与与block-ui模块的冲突有关。 Configure it blockUiConfig with autoblock = false;
使用autoblock = false将其配置为blockUiConfig;
