问题描述
已更新.
此代码块将用户的Facebook连接保存到"fbdata"中，并保存在div的"friends-list-container"中.
This code block takes the users facebook connections and saves them into the "fbdata" and within the div "friends-list-container".
这是有错误的页面.
然后我尝试将数据保存到parse.com，并在以下图片中显示以下错误.
I'm then attempting to save the data to parse.com and have the following error shown the image below.
<!doctype html>

var contact = new Parse.User();
var fbdata=response.data;
var divTarget=document.getElementById("friends-list-container");
for (var friendIndex=0; friendIndex<fbdata.length; friendIndex++)

divContainer.innerHTML="<b>" + fbdata[friendIndex].name + "</b>";
divTarget.appendChild(divContainer);
}
var contact = new Parse.User();
var contact = new Contact();
$(document).ready(function () {
var username = $("#friends-list-container").val();
contact.set("facebookFriends", fbdata.toString());
contact.save(null, {
success: function (results) {
// The object was saved successfully.
location.reload();
},
error: function (contact, error) {
// The save failed.
// error is a Parse.Error with an error code and description.
alert("Error: " + error.code + " " + error.message);
}
});
});
} else {
console.log('Something goes wrong', response);
}
});
}
});
};
(function(d, s, id){
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/all.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
<div id="friends-list-container"></div>
</body>
</html>
这是错误.
推荐答案
尝试替换此行:
var contact = Parse.Object.extend("_User");
从聊天对话中更新，这就是解决问题的方法:
Updated from the chat conversation, this is what solved the problem:
如果要将朋友列表存储在当前用户的数组中，则需要Parse.User.current():
If you want to store the friends list in an array on the current user, then Parse.User.current() is what you want:
var contact = Parse.User.current()
