未定义错误javascript

Question

我已经将所需的文件包括在头上，就像它在文档中说的那样。

<script src='https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js'></script>
<script src='https://cdn1.kongregate.com/javascripts/kongregate_api.js'></script>

然后，就在我的脚本上面，我包含了应该定义变量的脚本。

<script>
    kongregateAPI.loadAPI(function(){
        window.kongregate = kongregateAPI.getAPI();
    });
</script>

但是在控制台中，我仍然得到这个错误Uncaught ReferenceError: kongregate is not defined

Answer 1

你说过：

然后就在我的脚本上面

这是否意味着您的代码看起来像这样？

<script>
    kongregateAPI.loadAPI(function(){
        window.kongregate = kongregateAPI.getAPI();
    });
</script>
<script src='https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js'></script>
<script src='https://cdn1.kongregate.com/javascripts/kongregate_api.js'></script>

如果是这样的话，您应该在加载api文件之后调用kongregateAPI函数：

<script src='https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js'></script>
<script src='https://cdn1.kongregate.com/javascripts/kongregate_api.js'></script>
<script>
    kongregateAPI.loadAPI(function(){
        window.kongregate = kongregateAPI.getAPI();
    });
</script>

我试过了，一切正常。
