components

问题 I developed this app (http://www.anelmad.com) and I am trying to redirect the display of information (dictionary definitions of words) upon submit (Enter or button click) into another page. The redirection works but the content of the page does not follow. in home.component.html: <form #myForm> (...) <input type="text" class="form-control" #elem (keyup)="onNameKeyUp(elem.value)" [ngModelOptions]="{standalone: true}" [(ngModel)]="latinButton" (focus)="onNameKeyUp(elem.value)" placeholder=

问题 I have a component called "categories", where I have 2 buttons active and inactive. Each button calls an api to either activates or deactivates the selected record. However, the button part and the api part are running completely fine and getting proper response after getting the task done. But, I need the "categories" component to reload/re-render after the api response has returned the success code. I googled for the solution but the answers I got were little confusing for me because I am

问题 This is my first try at a simple React application. Working with the Openweather API and AXIOS. I took Stephen Grider's course on Udemy and I'm trying to create something on my own now, but I still have problems when passing data between components. I have a SearchBar component and I'd love to be able to pass the input value to the parent component's state, so I can then update it with each search and render it into the DOM. However, I keep running into errors. I tried passing a function as a

问题 I am trying to figure out how to respond to the warning in react to use javascript classes to create components in my MERN app. The warning says: Warning: Accessing createClass via the main React package is deprecated, and will be removed in React v16.0.

问题 I'm using a DateChooser, and want to show different information in a tooltip as the user rolls over each day. Is there an event that fires as I'm rolling around the calendar that will tell me what day I'm currently over? 回答1: It's a little complicated. You're going to need to use the mx_internal namespace. The grid portion of the DateChooser component is a CalenderLayout component in DateChooser.as. mx_internal var dataGrid:CalenderLayout; CalenderLayout.as has the mouseMoveHandler. In the

问题 I'm trying to clean up my components so that my container handles logic and my components are presentational only. I'm using Redux to connect my store to container/components. I'm trying this simple code, and I'm not sure why it is not working and what I'm missing. Previously I had, and it worked: var Main = React.createClass({ render: function(){ var style = this.props.hover; var actions = this.props.actions; return ( <div> <Bullet style={style} actions = {actions}/> </div> ); } }); function

问题 I'm trying to pass more than one argument in an ember action. The problem is that one of the arguments is value='target.value' and apparently Ember doesn't like to add a second one. How can I pass these two parameters? value='target.value' works if I only need one argument. I've tried to write it this way but category is undefined. {{#each selectorsData as |selectorItem|}} <select onchange={{ action selectorItem.action value='target.value' category='selectorItem.name' }}> I've tried this way

问题 I need to include jquery and form validations libraries into a specific component. I have already tried react-async-script-loader but couldn't get it to work.

However, I have the downloaded files to used in the Laravel public folder. Here is the error I am getting: Uncaught TypeError: Cannot convert undefined or

问题 I have two components: var A = React.createClass( { doSomething: function() { return "I am A" }, render() { return( <h1>{this.doSomething()}</h1> ); } }); class B extends A { doSomething(): any { console.log("I am B"); } } https://jsfiddle.net/wp4wshdu/ I have the same problem as here => How to override a parent class method in React?
