I use the third-party component named "slider" (rc-slider). I need to add an additional element inside the slider slider (div class = "rc-slider-handle").
<div class="rc-slider">
<div class="rc-slider-rail" style="..."></div>
<div class="rc-slider-track" style="..."></div>
<div class="rc-slider-step"></div>
<div role="slider" tabindex="0" ... class="rc-slider-handle" style="...">
// new element should be added here
</div>
<div class="rc-slider-mark"></div>
</div>
Using from my react component:
<Slider
min={...}
max={...}
value={...}
onChange={...}
/>
According to rc-slider docs, you're able to pass a handle prop:
<Slider
min={...}
max={...}
value={...}
onChange={...}
handle={() => <div className="rc-slider-handle" />}
/>

I'm using a library. Once I add the component, I don't have direct access to an element with the class "marquee". But I need to add a ref to it like so: Is there anyway I can do this?
<div className="marquee-container">
<div className="marquee" ref={needARefHere}>
<img />
<img />
</div>
</div>
I call this in my code:
<Marquee />
Hi I am trying to detect when a div is clicked that is nested inside of a container.
the goal is to extract the src for an image as a variable.
I want the path to the image
Would this work ?
<div className = "container">
<div onClick{divClicked()} className="column">
<img alt="" src={props.gif} className="ui image" />
</div>
</div>
divClicked() {
console.log(props.gif)
}
You cannot set an onclick like that.
<div onClick={divClicked} className="column">
this code should work if the divClicked function is in the same context.
If this function is a member of a class, you might want to use this.divClicked
Additionally if you want to pass parameters to the function you can use arrow functions to do this.
<div onClick={()=>divClicked(someParam)} className="column">
I am using React, Redux and Bootstrap setup. I am building book website that have different tabs in that tabs are items(books) that have the same id through the different tabs. All my data is stored in a store and passed down to panel like so: TabsContainer(here I filter the books and pass down via props)->[All, Favorites, ...]->List of Books (all the same for every one) -> Book (all the same).
It is hard to post all the code and also basic concepts since I don't have idea what could be wrong. I instead post the result.
This is where it is ok. I can also fix the bug by resizing the window, but then it bugges the other 4 tabs.
This is clearly a bug. Bugg happens always when I move aways from inital tab.
What could be wrong? Should I set different keys? But if I understand correctly the react would do necessary rendering.
Update Found the root of the evil is the react Equalizer that I used to match column sizes (bootstrap responsive) so that button row appeared on the bot. I believe that has to do with incompatibility with React. So the problem now is how to put button row on the bottom of the panel.
<div className="col-md-12 col-lg-6">
<div className="panel panel-default no-padding">
<div className="panel-body contentRow" style={book_item.mainContainer}>
<Equalizer>
<div className="col-xs-12 col-sm-6" style={book_item.imageContainer}>
<div>
<FavoriteIcon reading={reading} style={book_item.favorites}
onFavoriteChanged={this.onFavoriteChanged}/>
<Link to={"readings/"+reading.id+"/edit"} params={{id: reading.id}} style={book_item.imageLink}>
<img
src={'http://smartbooky.hopto.org/media/images/books/' + reading.book.id + '.jpg'}
height="210px" style={book_item.bookImage}/>
</Link>
</div>
</div>
<div className="col-xs-12 col-sm-6" style={book_item.textContainer}>
<div className="bookTitle">
<strong>{reading.book.title}</strong><br/>
</div>
<div className="bookSubtitle">
{(() => {
if (reading.book.subtitle)
return (<div><em>{reading.book.subtitle}</em> <br/></div>);
})()}
</div>
<div className="bookAuthors">
<div>{authors ? authors : "Unknown author"}<br/></div>
</div>
<div className="bookDescription hidden-xs" style={book_item.bookDescription}>
{truncatedDescription.replace(/<\/?[^>]+(>|$)/g, "")}
</div>
<div className="bookTags hidden-xs row" style={book_item.bookTags}>
{reading.book.genre ? BookCard.renderTags(reading.book.genre) : void(0)}
</div>
<div className="buttonRow"
style={window.innerHeight > 400 ? book_item.buttonRow : void(0)}>
<div className="col-xs-4">
<Button icon="glyphicon glyphicon-remove" name="Remove" kind="primary"
handleClick={this.onReadingDelete} style={book_item.buttonRemove} />
</div>
<div className="col-xs-4">
<Button icon="glyphicon glyphicon-th-list" name="Shelf" kind="primary"/>
</div>
<div className="col-xs-4">
<Button icon="glyphicon glyphicon-edit" name="Edit" kind="primary"/>
</div>
</div>
</div>
</Equalizer>

Creator of react-equalizer here. It is possibly an issue with the equalization happening before the image is loaded. I just published a new verion that fixes this issue (1.0.5).
Here is a working example with react-bootstrap tabs:
http://jsbin.com/mayanakiqo/edit?js,output
class MyComponent extends React.Component {
render() {
let colStyles = {
float: 'left',
width: '50%',
padding: '10px',
background: '#ddd',
border: '4px solid white',
boxSizing: 'border-box'
}
return (
<div>
<Tabs defaultActiveKey={2}>
<Tab eventKey={1} title="Tab 1">
<Equalizer byRow={false}>
<div style={colStyles}>
<img src="http://placehold.it/200x300" />
</div>
<div style={colStyles}>
Test content
</div>
</Equalizer>
</Tab>
<Tab eventKey={2} title="Tab 2">
<Equalizer byRow={false}>
<div style={colStyles}>
<img src="http://placehold.it/200x300" />
</div>
<div style={colStyles}>
Test content
</div>
</Equalizer>
</Tab>
<Tab eventKey={3} title="Tab 3">
<Equalizer byRow={false}>
<div style={colStyles}>
<img src="http://placehold.it/200x300" />
</div>
<div style={colStyles}>
Test content
</div>
</Equalizer>
</Tab>
</Tabs>
</div>
)
}
}
The other option would be to use flexbox to equalize the heights see https://codepen.io/imohkay/pen/gpard for example however it will depend on what browsers you need to support.
I think before answering this there are some things we need to know:
1. Do these Bootstrap tabs implement some sort of non-React JavaScript in terms of switching between them? I know that Bootstrap not only provides CSS files for installation, but it also can provide some JavaScript too to use some of its components.
2. I am guessing that in the pictures you posted, you are navigating from the Favorites Tab, to the All tab? If so, what SHOULD the All tab show? (It is possible that it is actually rendering the intended elements, and it is just the css that is making it look wrong.)
3. If the top two points are not the source of the problem, then we will need to see some code, at least for the render functions of the components involved, as well as what their states look like.
I am new to React and am trying to get up to speed on a few basic concepts, trying to shoehorn it into an existing application (with the intention of slowly converting the entire app into React). So this may be a vary basic question.
I am converting my dialogs first (my app has a bunch of bootstrap modal dialogs), so I am using react-modal library to create these dialogs. What I would like to do is make the outer markup for this dialog reusable across all my dialogs. For instance, with this render method:
render() {
return(
<Modal
className="Modal__Bootstrap modal-dialog"
closeTimeoutMS={150}
isOpen={this.state.modalIsOpen}
onRequestClose={this.handleModalCloseRequest}
>
<div className="modal-content">
<div className="modal-header">
<button type="button" className="close" onClick={this.handleModalCloseRequest}>
<span aria-hidden="true">×</span>
<span className="sr-only">Close</span>
</button>
*******INSERT HEADER COMPONENT*******
</div>
<div className="modal-body">
*******INSERT BODY COMPONENT*******
</div>
<div className="modal-footer">
<button type="button" className="btn btn-default" onClick={this.handleModalCloseRequest}>Cancel</button>
*******INSERT ADDITIONAL FOOTER BUTTONS COMPONENT*******
</div>
</div>
</Modal>
);
}
I would like to have the lines that start with the ******** to be variable components that are appropriate (and different) for each dialog.
Obviously, for each dialog, I could just copy and paste this render method into that dialog's class and have hard coded components for that dialog. Something like (for the body):
<div className="modal-body">
<DialogABody />
</div>
and:
<div className="modal-body">
<DialogBBody />
</div>
But if I do that, I am then duplicating all the markup for the dialog "chrome" in react.
Essentially, I need some sort of dynamic component?
Is this possible?
on your modal react class you want to do this
class Modal extends React.Component {
render() {
return (
<div>
{this.props.header ? <HeaderComponent text={this.props.header} /> : null }
{this.props.children}
{this.props.footer ? <FooterComponent text={this.props.footer} /> : null }
</div>
}
}
then when calling this pass your props
<Modal
className="Modal__Bootstrap modal-dialog"
closeTimeoutMS={150}
isOpen={this.state.modalIsOpen}
onRequestClose={this.handleModalCloseRequest}
header="My Header"
footer="My Footer"
>
as for the body component part you should pass that as a prop to this dialog class when calling it.
instead of this:
<div className="modal-body">
<DialogABody />
</div>
you should have this:
<div className="modal-body">
{this.props.dialogComponent}
</div>
which gets passed through on the parent to this class
Call your model dialog with the wanted components as props.
<model header={headerComponent} body={bodyComponent}/>
In model render just put {this.props.header} and so on.
for one child component you could simply use this.props.children, however, as you have 3 components, you need to put them into separate props:
<DialogBody header={<div>header</div>} body={<div>body</div>} footer={<div>footer</div>}/>
I have a simple ng-repeat generating image divs. I want them to come out in rows of 4 instead of one long vertical list. How can I do this?
<div ng-repeat="artist in artists">
<div>
<h3> {({ artist.fields.title })} </h3>
<img src="{({ artist.fields.link })}" />
</div>
</div>
I believe you want to do something like this
<div style="width:800px;">
<div ng-repeat="artist in artists" style="width:200px;float:left;">
<div>
<h3> {({ artist.fields.title })} </h3>
<img src="{({ artist.fields.link })}" />
</div>
</div>
</div>
By having a container with a fixed width, and having each element inside be 1/4 of that width you can achieve what you want.
Of course, inline styles shouldn't be used in real code :)
You can use the $index property to add a tag every 4th item. Then use some CSS to display items as desired:
<div ng-repeat="artist in artists">
<div class="someClass">
<h3> {({ artist.fields.title })} </h3>
<img src="{({ artist.fields.link })}" />
</div>
<br ng-if="artist.$index % 4 == 0" />
</div>
One way is to use css properties. attach a class to the div with a float:left attribute, and insert a br tag after every 4th div
I guess you are using bootstrap?
If yes, this thread could do a help:
