我正在尝试遍历此数组:
events: [{
"id": "123",
"key": "1",
"type": "academic",
"time": "2015 - 2016",
"title": " MSc in Software Engineering",
"place": "University of Oxford",
"location": "Oxford, United Kingdom",
"description": "Lorem impsum",
"gallery": []
},
{
"id": "234",
"key": "2",
"type": "professional",
"time": "2015 - 2016",
"title": " Software Engineer",
"place": "University of Oxford",
"location": "Oxford, United Kingdom",
"description": "Lorem impsum",
"gallery": [
{
"index": 11,
"url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash2/v/t1.0-1/p160x160/10923196_10204583699694173_6145976884213630323_n.jpg?oh=bd235908314ecf0ab5afa8d3f92f5abf&oe=567B51F9&__gda__=1450897067_285c7c8c720c0f130453b37e9ff9b2f8"
}
]
},
{
"id": "567",
"key": "3",
"type": "misc",
"time": "2015 - 2016",
"title": " MSc Software Engineering",
"place": "University of Oxford",
"location": "Oxford, United Kingdom",
"description": "Lorem impsum",
"gallery": [
{
"index": 1,
"url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash2/v/t1.0-1/p160x160/10923196_10204583699694173_6145976884213630323_n.jpg?oh=bd235908314ecf0ab5afa8d3f92f5abf&oe=567B51F9&__gda__=1450897067_285c7c8c720c0f130453b37e9ff9b2f8"
}
]
}
]
我的代码:
events.map(( timelineEvent ) => {
let directions;
if (timelineEvent % 2 == 0) {
directions = "direction-r";
} else {
directions = "direction-l"
}
return (
<li key={timelineEvent.id}>
<TimelineEvent
type = {timelineEvent.type}
time = {timelineEvent.time}
title = {timelineEvent.title}
place = {timelineEvent.place}
location = {timelineEvent.location}
description = {timelineEvent.description}
direction = {directions}>
<div>gallery</div>
<TimelineEditButton
deleteClick={timelineEvent.id}
dataId={ timelineEvent.id}
editClick={this.openPartial.bind(this, "editEventPartial")} />
</TimelineEvent>
</li>
);
});
但是出现以下错误:
Error: Invariant Violation: Objects are not valid as a React child (found object with keys {id, key, type, time, title, place, location, description, gallery}). If you meant to render a collection of children, use an array instead or wrap the object using React.addons.createFragment(object).
由于我是React的新手,所以我不知道是什么原因造成的。我正在使用React 0.14-rc1。
有人可以指出这个问题吗?谢谢
最佳答案
您使用过timelineEvent % 2 == 0
,也许是问题所在?由于timelineEvent是一个对象,因此我猜您想在“索引”或timelineEvent.id
而不是整个对象上执行此操作。
