components

问题 I've been rewriting directives in Angular 1.5.8 to components. I want to write unit tests with '$componentController` just like described here: https://docs.angularjs.org/guide/component. The problem is that I'm getting error at this line: var ctrl = $componentController('componentName', null, bindings); saying: undefined is not a constructor (evaluating 'compileProvider.preAssignBindingsEnabled()') app/lib/angular-mocks/angular-mocks.js:2235:80 So it looks like $compileProvider doesn't have

问题 I have this code in start method: ObservableList<StringBuilder> list = FXCollections.observableArrayList(); list.add(new StringBuilder("0")); list.add(new StringBuilder("1")); list.add(new StringBuilder("2")); list.add(new StringBuilder("3")); list.add(new StringBuilder("4")); list.add(new StringBuilder("5")); list.add(new StringBuilder("6")); list.add(new StringBuilder("7")); list.add(new StringBuilder("8")); list.add(new StringBuilder("9")); ComboBox<StringBuilder> combo = new ComboBox<>

问题 I seem to be unable to render components using name strings. I wanted to be able to dynamically generate component name strings which have existing corresponding components that can be rendered. The array const is going to be populated via JSON data, that's why I need to use string values for identifying the component. Here is what I'm trying to do: import Module1 from './module1'; import Module2 from './module2'; import Module3 from './module3'; const array = ['Module1', 'Module2', 'Module3'

问题 I need to change the functionality in a component. What do you do when you get a "you can't override this" message, or you need to change the code in a private method ("method does not exist in base class" message), rendering it impossible to descend the component? 回答1: If I face that problem, I first try to inherit from the component, or its CustomXXX ancestor and see if that fixes the problem. If that doesn't, I go deeper, i.e. try to intercept the messages that come in. That can be done

问题 Running CF 9,0,1,274733 I have a custom DAO CFC with a method called getGamesBetTypesID(). The method is generated/synthesized implicitly by CF from the following property: <cfproperty name="gamesBetTypesID" type="numeric" /> A default variable is defined as follows: <cfset VARIABLES.gamesBetTypesID = 0 /> Other than that there are no other VARIABLES, vars, LOCALs, ARGUMENTS or methods called getGamesBetTypesID. All CFC and function variables are correctly scoped. This save() method is called

问题 The Angular 2 docs say to define a component like this, using a magic string for the selector name: import { Component } from '@angular/core'; @Component({ selector: 'card', template: ` <div class="card">{{title}}</card> ` }) export class Card { title = 'Card Title'; } If I do this, am I stuck with <card> as the only way to use this component in the future? Can an app have only one type of component with this selector? For example, is it possible to use a <card> from a third-party library,

问题 Problem: Currently, I have a LoginForm component that has an "on-success" handler function handleOnSuccess . This the then linked to the parent component with an onTokenUpdate property defined by a "token-update" handler function handleUpdateToken . The problem is that the setState in the handleUpdateToken function is forcing an undesired rerender. Desired Outcome: What I ultimately need is to update the LoginForm component property token with the value obtained on success WITHOUT performing

问题 I have an api which provides me a with Webpack processed react component which looks like the following: module.exports=function(e){var t={};function r(n){if(t[n])return t[n].exports;var u=t[n]={i:n,l:!1,exports:{}};return e[n].call(u.exports,u,u.exports,r),u.l=!0,u.exports}return r.m=e,r.c=t,r.d=function(e,t,n){r.o(e,t)||Object.defineProperty(e,t,{enumerable:!0,get:n})},r.r=function(e){"undefined"!=typeof Symbol&&Symbol.toStringTag&&Object.defineProperty(e,Symbol.toStringTag,{value:"Module"}

问题 I'm new user of ReactJS and I bumped in a point. I'm creating a generic map component, it works perfectly. However, only can render one component by page. I would like to instead use getElementById , I could use getElementsByClassName . Is it possible? I would like to leave my system generic, where I use many components in same page. In the example, I use to render 1 map, but if I want to use with 2 or more maps? <div class="MyMap" comp-url="https://www.google.com/maps/embed?pb=!1m18!1m12!1m3
