问题 I'm trying to build a sort of dynamic dashboard using Angular 1.5.8. I've made decent progress up until the final hurdle. Which is actually rendering the dynamic component.

问题 I'm writing an Angular 1.5 directive and I'm running into an obnoxious issue with trying to manipulate bound data before it exists. Here's my code: app.component('formSelector', { bindings: { forms: '=' }, controller: function(FormSvc) { var ctrl = this this.favorites = [] FormSvc.GetFavorites() .then(function(results) { ctrl.favorites = results for (var i = 0; i < ctrl.favorites.length; i++) { for (var j = 0; j < ctrl.forms.length; j++) { if (ctrl.favorites[i].id == ctrl.newForms[j].id) ctrl

I have default props in my React component: PropertyTitleLabel.defaultProps = { bedrooms: 1, propertyType: 'flat' }; PropertyTitleLabel.propTypes = { bedrooms: PropTypes.number, propertyType: PropTypes.string }; But when I'm passing null to bedrooms like: const bedrooms = null; // in real world API returns `null` <Component bedrooms={bedrooms} /> It's not replaced with default prop :( Any ideas? You can change the null value to undefined to use the default value. <Component bedrooms={bedrooms || undefined} /> I think there's a distinction between null and undefined that is made when dealing

Angular2 Component @Input two way binding

阅读更多关于 Angular2 Component @Input two way binding

问题 I have a data driven Angular application. I have a toggle component which I pass in a toggled state. My issue is that the two way data binding does not seem to work unless i pass in the toggle boolean as an object. Is there a way to get this to work without using an EventEmitter or passing the variable in as an object . This is to be a reusable component and the application is heavily data driven so passing the value in as an object in not an option. My code is.... toggle.html <input type=

Closed. This question is off-topic. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it's on-topic for Stack Overflow. In my analysis of the newer web platforms/applications, such as Drupal, Wordpress, and Salesforce, many of them create their software based on the concept of modularization: Where developers can create new extensions and applications without needing to change code in the "core" system maintained by the lead developers. In particular, I know Drupal uses a "hook" system, but I don't know much about the engine or design

I want to create a simple form builder with Vue where users click on buttons from a menu to add different form fields to a form. I know that if there was just one type of form field to add, I could do it with something like this ( https://jsfiddle.net/u6j1uc3u/32/ ): <div id="app"> <form-input v-for="field in fields"></form-input> <button type="button" v-on:click="addFormElement()">Add Form Element</button> </div> <script type="x-template" id="form-input"> <div> <label>Text</label> <input type="text" /> </div> </script> And: Vue.component('form-input', { template: '#form-input' }); new Vue({

Angular 2 nested forms with child components and validation

阅读更多关于 Angular 2 nested forms with child components and validation

I'm trying achieve a nested form with validation in Angular 2, I've seen posts and followed the documentation but I'm really struggling, hope you can point me in the right direction. What I am trying to achieve is having a validated form with multiple children components. These children components are a bit complex, some of them have more children components, but for the sake of the question I think we can attack the problem having a parent and a children. What am I trying to accomplish Having a form that works like this: <div [formGroup]="userForm" novalidate> <div> <label>User Id</label>

React - how to pass state to another component

阅读更多关于 React - how to pass state to another component

问题 I'm trying to figure out how to notify another component about a state change. Let's say I have 3 components - App.jsx,Header.jsx,and SidebarPush.jsx and all I'm simply trying to do is toggle a class with an onClick. So the Header.jsx file will have 2 buttons when clicked will toggle the states to true or false. The other 2 components App.jsx and Header.jsx will need to know about these state changes so they can toggle a class whenever those states change. App.jsx import React from 'react';
