Clash Royale CLAN TAG #URR8PPP What is the best approch to send data to its descendant in REACT FOr example I have one parent component ( i'll call it animal) and several child components (dog, cat, horse) and child's child components (Collie, English Foxhound, Fox Terrier, German Shepherd Dog). If i wanna send a function from animal to Collie, i have to send this function to Dog component and from Dog to Collie and only after 2 props i will be able to use this function in Collie component. Is there any better approch to send a function from animal directly to Collie ? 2 Answers 2 Use the Context API. Read more at the official docs : https://reactjs.org/docs/context.html Basically, you define a context value and pass it with a Provider, which can be accessed by any node within the child tree. Do note that the Context API is different for different versions of React and may change in future.

Clash Royale CLAN TAG #URR8PPP How do you style an image in an <a> tag? Here's some code that contains a tags, one which contains an image. a <div class="container"> <a href="#">Not styled</a> <a href="#"><img src="image.png"></a> </div> If I only want to style the image, how would I do it (without creating a class or something similar)? For example, if I want to style all the a tags, I could use the following CSS: a .container a { /* styles here */ } If I want to style all the img tags, I could use this: img .container img { /* styles here */ } Is there a way to apply this same logic to an img in an a tag? img a Edit: Here are the styles I'm applying. For some reason, when I use .container a img it adds extra padding/margins. .container a img .container a { padding: 9px 10px 5px 10px; } Edit 2: I think the problem lies elsewhere.

Thanks 5 Answers 5 One way to accomplish this is base64 encoding the PKCS#12 file. This, for instance, works with PHP openssl_pkcs12_export( $strCertPEM, $strCertPkcs12, $resKey, $strCertPW ); $arrCertBase64 = str_split( base64_encode($strCertPkcs12), 52); $xmlUserCertPlist = plistVar('PayloadContent',$arrCertBase64,'data'); function plistVar($key,$var,$type) { //...snip... if ( $type == 'data' ) return plistData($key,$var); /

Clash Royale CLAN TAG #URR8PPP Better method to check all objects' parameters with a single call I want to get all objects which age is less than 18. How can easily do that? Should I had to pass all objects to get_nonage to get it? class People: def __init__(self, uid, age): self.uid = uid self.age = age def get_nonage(self): # print nonage here which age<18 # expected output: {1: 11, 3: 15} pass p1 = People(1, 11) p2 = People(2, 20) p3 = People(3, 15) ... People.get_nonage() People.get_nonage() First, get_nonage should probably not be an instance method. Second, yes, you will have to pass it all of the People object if you want it to search all of the People objects. But that implies that you should be storing them in a list, instead of in a bunch of separate variables. Then you just pass the list. – abarnert 13 mins ago
