问题 i have a Spring-rest api with full OAuth2 authentication in it. Now i want to implement a front end for the api with Angular2. This is my first Angular2 app and my first front end app. I feel like i have searched the whole internet on how to do this, and found some tutorials but when i tried to apply it in my angular app it always went something wrong. So i've decided to do it on my own. I have already some services which can send http request and get a response for example to get a user from

问题 I find flex box really useful, and since I discovered it I am tempted to use it everywhere. Question Is it a good practice to nest flex-boxes? Does having a lot of them and especially nested ones has an impact on performance? 回答1: In short yes you will see dip in performance by around 10x we are still talking milliseconds here though. So I would be wary of using a lot of them because one could change render speed from 10MS to 100MS a lot of them could in essence highly increase the render

问题 I have a custom role in functions.php: add_role('test_pilot', 'Test Pilot', array( 'read' => true, 'edit_posts' => true, 'delete_posts' => true, )); // Give the custom role a new level $test_pilot = get_role('test_pilot'); $test_pilot->add_cap('level_3'); ...and on the front-end I'm trying to echo the delete post link: <?php echo get_delete_post_link( get_the_ID() ); ?> The problem is the link isn't actually being displayed when logged in as a user with the test pilot role. If I am logged in

问题 I have an inline editable table (I used Tabledit for this) and each row has an ID and the IDs should be passed to the controller action (Yii2) in order for me to save edited data to the database. Here's my Tabledit code in my js file: file.assetID = info.response; // the ID for (var i = 0; i < file.length; i++) { // the table if (file[i].type == "image/jpeg") { var type = "photo"; } else if (file[i].type == "video/mp4") { var type = "video"; } messageHtml += '<tr id="' + file[i].assetID + '">

问题 Firstly, apologies for the lack of code on this, I'm just looking for clarity on if it can be done and what APIs/libraries will allow me to do so. I have a web app front-end written in Angular. One of the back-end services it fetches data from can often take 2-3 mins to return, due to the location of the server and the nature of the data returned. Right now I have an animated spinner displayed on the front-end until the response is returned, which isn't great, as this prevents the user from

问题 Here is the code snippet about an Angular Controller. I'm trying to learn Angular from this github project The questionable part is located in function addStock . I have already defined $scope.watchlist in the initilizations part, however, if I remove the re-declaration inside $scope.addStock function, $scope.watchlist will not be populated with right values. Can any Angular experts point me out? If you want to see my full project code - here is the link. angular.module('stockCatApp')

问题 this is the second part of a bigger problem where the first part was solved here React native project deleted on xcode, can't run "run-ios react-native". I have deleted my project on Xcode may it be .xcworkspace or .xcodeproje. Because of that, I had to delete IOS and android folders while downgrading, updating and re-upgrading my react version to re-install IOS and android folders. Thanks to that the emulator is working but unfortunately the project isn't present in the emulator and is still

问题 I'm currently working on angular 6 app. I have a huge list of articles and want to do some filtering upon it. Right now it works real-time, there is no button to submit your filter options, it all happens as you type. I figure a way, but it has still some issues I can fix, but doesn't like the way I did it. I'm sure, there has to be something more elegant. For better imagination those articles have category, title, author, tags. I am able to filter them according to category lets say... but I

问题 I have recently learned that target="_blank" is vulnerable and we have to use rel="noopener" . I am working on a website project where all anchor tags are using the target attribute. It is possible to change the colors of these anchor texts at once just by using: a {color: blue;} in the head of the website. But If I try to do a { rel="noopener" target ="_blank" } The above code does not have any effect. Because rel and target are not covered in CSS . So how could someone set these attributes

问题 beginners question. The error says it can't find a variable: "View" I have written this code in order to integrate a design to my code but it is giving: "can't find variable: View " what am I missing import React from 'react'; import {StyleSheet} from "react-native" ; export default class MenuButton extends React.Component { render() { return ( <View menu={burger.menuIcon}> </View> ) } } const burger = StyleSheet.create({ menuIcon: { color : 'rgba(255,255,255,0.0)', top : 17 , height : 5 ,
