在角度oi选择多个选项中覆盖的ng-init值
问题描述：
我正在使用ng-repeat动态表单。我正在使用oi-select库来加载我的位置。 oi选择框具有多选功能。在我的页面加载默认情况下，我正在加载第一个选项值在该oi选择框中。在角度oi选择多个选项中覆盖的ng-init值
但我正在使用多选功能，如果我选择任何其他选项，而不是第一个选项，它会被该值覆盖。由于这个问题，我必须再次选择第一个选项。我的问题是，我如何将默认的第一个选项值加载到oi-select中？
之后，如果我选择的任何其他选项则无法覆盖在选择框中我的第一个值。这里是我的plunker链接http://plnkr.co/edit/m6Q02dlHLBCMVLRLfioh?p=preview

答
如果使用
multiple属性，这个我ans模型应该是一个数组而不是字符串，因为在你的情况user.location = $scope.locations[0];中，ypu必须将其更改为location: []并使用push()method将初始项添加到此数组;使用
$timeout对我没有任何意义;ngInit在模板中增加了不必要的逻辑量，我宁愿避免在你的情况下使用它，只需在你的控制器中使用location: [$scope.locations[0]]。
工作例如：
var app = angular.module('myApp', ['ngResource', 'oi.select']);
app.controller('myCtrl', function($scope, $timeout) {
$scope.ids = [1, 2];
$scope.locations = ['india', 'usa', 'jermany', 'china', 'Dubai'];
$scope.users = $scope.ids.map(function(id) {
return {
id: id,
comment: "",
location: []
};
});
$scope.initLocation = (user, locations) => {
if (!user.location.length) {
user.location.push(locations[0]);
}
}
$scope.adduser = function() {
$scope.users.push({
id: Math.max(...($scope.users.map(u => { return u.id; }))) + 1,
comment: "added from controller",
location: [$scope.locations[2]]
});
}

是你能解决这个问题？ –
如果位置是静态数据，它工作正常。但根据我的新要求，我在模态弹出窗口中加载此表单。我的位置值来自api调用。只有第一次，如果我点击我的模态弹出按钮我的第一个位置数据默认情况下没有加载选择框，ng-init（）方法不起作用。但如果我再次点击弹出按钮它的工作正常。第一次没有加载第一个位置值。我在这里附上了我的plunker链接。请帮助我.https：//plnkr.co/edit/xDVetaZIzpFdKLS9ihU6？p =预览 – user3760261
