EmberJS“此”更改了promise（查找）回调 [英] EmberJS "this" changed in promise (find) callback

问题描述

当我想通过控制器操作从服务器获取帐户时，例如：

When I want to fetch an account from the server in an controller action e.g:

account: false,

actions: {

    // When the oAuth popup returns this method will be called
    fetchUser: function(id)
    {           
        // Get the account from the server
        this.store.find('account', id).then(function(account)
        {
            this.set('account', account);
        }, function(error)
        {
            console.log('error', error);
        });

    },
}

由于 this.set（'account'，account）行上的 this不再是控制器。

It throws an error because "this" on the line this.set('account', account) is no longer the controller. How can I set "account" on the controller now from within this promise callback?

推荐答案

account: false,

actions: {

// When the oAuth popup returns this method will be called
fetchUser: function(id)
{           
    // Get the account from the server
    this.store.find('account', id).then(function(account)
    {
        this.set('account', account);
    }.bind(this), function(error)
    {
        console.log('error', error);
    });

},

}

解决了！添加.bind（this）:-)

Fixed it! added .bind(this) :-)
