Javascript 无法将数据绑定到angularjs中的下拉式multiselect

请检查一下这个箱子。我无法像这样绑定来自服务器的数据

（[“周一”、“周二”）

我知道数据绑定的时候就像

$scope.selectedUser = [{ id: 2, name: 'Monday' },
                       {id: 3,name:'Tuesday'}];.

我想用javascript将

[“星期一”、“星期二”]

转换成

[{id:2，name:'Monday'}，{id:3，name:'tuday'}]

，这样它就可以在下拉列表中绑定

请帮我解决这个问题

你可以这样做

$scope.selectedUsers=[];
//serverData is data from server
for(var i =0 ; i < serverData.length ; i++){
    $scope.selectedUsers.push({id:i , name: serverData[i]})
}

$scope.selectedUser

应具有对

$scope.users

中实际对象的引用。例如，这是我必须在您的plunker中更改的内容，以便将其与用户名列表中匹配的用户绑定：

var defaultSelectedUsers = ["Sunday","Tuesday"];

$scope.users = [
   { id: 1, name: 'Sunday' },
   { id: 2, name: 'Monday' },
   { id: 3, name: 'Tuesday' } ];

$scope.selectedUser = $scope.users.filter(function(user){
    return defaultSelectedUsers.indexOf(user.name) != -1;
});

您提到要从服务器的响应执行此操作。假设根据您的示例，您依赖默认的按名称选择的用户，则不清楚您希望如何决定选择哪一个

这是处理服务器响应和修改新选定用户的方式：

var defaultSelectedUsers = ["Sunday","Tuesday"];

$http.get('/api/v1/users')
    .success(function(users)){
        $scope.users = users;

        $scope.selectedUser = users.filter(function(user){
            return defaultSelectedUsers.indexOf(user.name) != -1;
        });
    });

您可以将筛选条件更改为对您有意义的条件

使用以下代码实现json

var temp = ["Monday", "Tuesday"]
var result = "[";
for (var i = 0; i < temp.length; i++) {
if(i!=temp.length-1)
{
    result += "{id:'" + i + "',name:'" + temp[i] + "'},";
}
else
{
    result += "{id:'" + i + "',name:'" + temp[i] + "'}";
}
    alert(result);
}
console.log(result+"]")

var temp=[“星期一”、“星期二”]
var result=“[”；
对于（变量i=0；i

//这是从服务器获取数据时创建id的ng筛选器
app.filter（'createId'，function（）{
返回函数（arr）{
var结果=[]；
对于（变量i=0；i

你想做什么？虽然我从前面的评论中得到了答案，但这也是非常有用和简单的。。非常感谢。

var temp = ["Monday", "Tuesday"]
var result = "[";
for (var i = 0; i < temp.length; i++) {
if(i!=temp.length-1)
{
    result += "{id:'" + i + "',name:'" + temp[i] + "'},";
}
else
{
    result += "{id:'" + i + "',name:'" + temp[i] + "'}";
}
    alert(result);
}
console.log(result+"]")

//This is the ng filter to create id as you get the data from server 
app.filter('createId',function(){
    return function(arr){
        var result = [];
        for(var i = 0;i < arr.length;i++){
            var id = arr[i].substring(0,3);
            var obj = {'id':id,'name':arr[i]};
            result.push(obj);
        }
        return result;
    }
});

//In js controller you can costomize your array of user by using ng-filter like this
$scope.users = $filter('createId')($scope.users);
//This is because index will be changed every time so this can't be used as ID
$scope.selectedUser = $filter('createId')($scope.selectedUser);
