我在iOS模拟器中运行我的React Native应用程序,我正在尝试使用BVLinearGradient.我按照github自述文件中的所有说明进行操作,但是我收到了与BVLinearGradient相关的错误.
在开发者控制台中,我看到:
警告:"BVLinearGradient"的本机组件不存在
当我直接从XCode运行时,我看到:
'React/RCTViewManager.h' file not found(在BVLinearGradientManager.h中)
'React/RCTView.h' file not found(在BVLinearGradient.h中)
这里发生了什么?谢谢.
我正在尝试在我的EC2 Instance for AWS上设置我的laravel项目.我已经使用SFTP成功将文件上传到服务器,并重写了000-default.conf文件以指向项目的公共文件夹.
本地路线装载正常,但其他路线都没有工作?知道这里发生了什么吗?它们都可以在本地主机(MAMP)和其他服务器上正常工作.

我正在尝试在我的网络应用中实施Strip付款.但是,在使用示例代码时,我收到了js错误:

<script>
Stripe.setPublishableKey('pk_test_HnjFihOWwYTWnnsTLnZTmbgv');
var handler = StripeCheckout.configure({

token: function(token) {
// Use the token to create the charge with a server-side script.
// You can access the token ID with `token.id`
}
});
$('#customButton').on('click', function(e) {
// Open Checkout with further options
handler.open({

});
e.preventDefault();
});

我有一个看起来像这样的数组:
var skillsets = [
{id: 'one', name: 'george'},
{id: 'two', name: 'greg'},
{id: 'three', name: 'jason'},
{id: 'four', name: 'jane'},
];
Run Code Online (Sandbox Code Playgroud)
我想要做的是根据使用Javascript以id形式给出的值来查找行.例如,如果我将"id ='two'"放入函数中,我希望将"1"作为行返回.
我知道对于单行数组,skillsets.indexOf ['value']可以工作,但这对于这个JSON集不起作用.
我怎样才能做到这一点?
