问题 I'm trying to learn how to make plugins work in Angular, however after adding systemjs I get the following error: Uncaught ReferenceError: SystemJS is not defined I implemented systemjs like this: import { System } from 'systemjs'; declare const SystemJS: System; import * as angularCore from '@angular/core'; import * as angularCommon from '@angular/common'; import * as angularCommonHttp from '@angular/common/http'; import * as angularForms from '@angular/forms'; import * as angularAnimations

问题 I've got a custom tooltip being pulled by Ajax, when you rollover a link, great...e.g. <script type="text/javascript"> $(document).ready(function(){ $('.tippytrip').hover(function(){ var tooltipId = this.hash; $('#tooltip-container').empty().load('tooltips.html ' + tooltipId).show(); }, function(){ $('#tooltip-container').hide(); });}); </script> So this shows the div... "tooltip-container" But I think i'll need some further jQuery assistance in actually positioning the tooltip next to each

问题 I would like to develop a web application for Samsung Gear Fit 2 pro, but I have problems with getting an emulator to work. Do you know which emulator I should use?

问题 I'm struggling in a Flutter situation with multiple navigators. Concept here is a page which triggers a modal with his own flow of multiple pages. Inside the modal everything is going swiftly (navigation pushes/pops are working), but if the modal is dismissed it removes every page of the lowest navigator. I've looked at the example of https://stackoverflow.com/a/51589338, but I'm probably missing something here. There's a wrapper Widget inside a page which is the root of the application.

问题 I'm doing an at-home project basically just for fun but I'm having more trouble than anticipated.

My code currently is as follows -> import cv2 import numpy as np # Read in the image in grayscale img = cv2.imread('/home/pi/Downloads/divot1.jpeg', cv2.IMREAD_GRAYSCALE) params = cv2

问题 I am having a little bit of a problem here. I am trying to figure out how to catch the IllegalArgumentException. For my program, if the user enters a negative integer, the program should catch the IllegalArgumentException and ask the user if he/she wants to try again. But when the exception is thrown, it doesn't give that option. It just terminates. I tried to use the try and catch method but it doesn't work for me. How do I catch this particular exception to continue to run instead of

问题 How can i display different labels under each column and also have another label for the entire group? As you can see in the picture below i want to use fontawesome icons for each column but another label for the main group. I found other answers how to use fa icons but don't know how to position them under each bar. The trendlines which connect distinct columns are not so important but would be great if i can find out how to add them also. Also the chart needs to be scrollable as it can hold
