QUESTION

How have a image in the center of the dashboard header in Shinydashboard R?

Asked 2022-Jan-13 at 21:58

I have the following code that makes a simple shiny app.

```
library(shinydashboard)
library(shiny)
ui <- dashboardPage(
  dashboardHeader(title = tags$img(src='https://cdn.vox-cdn.com/thumbor/Ous3VQj1sn4tvb3H13rIu8eGoZs=/0x0:2012x1341/1400x788/filters:focal(0x0:2012x1341):format(jpeg)/cdn.vox-cdn.com/uploads/chorus_image/image/47070706/google2.0.0.jpg', height = '60', width ='100')),
  dashboardSidebar(
    sidebarMenuOutput("menu")
  ),
  dashboardBody()
)

server <- function(input, output) {
  output$menu <- renderMenu({
    sidebarMenu(
      menuItem("Overview", icon = icon("tachometer"))
      
    )
  })
}
shinyApp(ui, server)
```

And the image is outputted on top of the menu to the right, but my goal would be to have the image be more in the middle of the dashboard. I know the menu shifts the navabr a bit but I would like to keep it as center as possible.

But my desired output would be like this. I made a sample with paint. Is it possible to still have some text or if a reference can be posted where I can learn more about the dashboard header function I would appreciate it.

Here you go

There is no way you can add the image to the header part on the right side with the function from shinydashboard, but let's have fun with the latest htmltools by injecting styles and tags into the header.

library(shinydashboard)
library(shiny)
header_img <- tags$img(
    src='https://cdn.vox-cdn.com/thumbor/Ous3VQj1sn4tvb3H13rIu8eGoZs=/0x0:2012x1341/1400x788/filters:focal(0x0:2012x1341):format(jpeg)/cdn.vox-cdn.com/uploads/chorus_image/image/47070706/google2.0.0.jpg',
    style = 'height: 50px; width: 100px; position: absolute; left: 50%; transform: translateX(-50%);'
)
header <-  htmltools::tagQuery(dashboardHeader(title = ""))
header <- header$
    addAttrs(style = "position: relative")$ # add some styles to the header 
    find(".navbar.navbar-static-top")$ # find the header right side
    append(header_img)$ # inject our img
    allTags()

ui <- dashboardPage(
    header,
    dashboardSidebar(
        sidebarMenuOutput("menu")
    ),
    dashboardBody()
)

server <- function(input, output) {
    output$menu <- renderMenu({
        sidebarMenu(
            menuItem("Overview", icon = icon("tachometer"))
            
        )
    })
}
shinyApp(ui, server)

The img is placed on the center of right side header, not the center of the entire header length. If you want to adjust to the center of the whole length, try to change translateX(-50%) of the img to a number you like.

QUESTION

How can I extract the link to the image here?

Asked 2021-Aug-04 at 07:27

I'm using BS4 to scrape webpages for article titles, author names, and links to their cover images.

This is the HTML tag I found for the image of a specific article:

<img src="https://cdn.theatlantic.com/thumbor/lYaNkJfiPr8_Jp5Pj5ikj94GJgQ=/183x0:2000x1125/210x130/media/img/2021/06/WEL_Tiffany_KodakOpenerAlt-1/original.jpg" alt="Photo collage on a yellow background" loading="lazy" class="Image_root__J8Wlz Image_lazy__1w_jB Image_loaded__3uNg2 LandingRiver_image__1ZCUb" width="210" height="130" srcset="https://cdn.theatlantic.com/thumbor/lYaNkJfiPr8_Jp5Pj5ikj94GJgQ=/183x0:2000x1125/210x130/media/img/2021/06/WEL_Tiffany_KodakOpenerAlt-1/original.jpg, https://cdn.theatlantic.com/thumbor/NL-ZZp6sHiX_1WX2bn9f9o1WWjk=/183x0:2000x1125/420x260/media/img/2021/06/WEL_Tiffany_KodakOpenerAlt-1/original.jpg 2x">

This is the code I'm using to get the image URL:

cover_image = card.find('img')['src']

However, instead of

"https://cdn.theatlantic.com/thumbor/lYaNkJfiPr8_Jp5Pj5ikj94GJgQ=/183x0:2000x1125/210x130/media/img/2021/06/WEL_Tiffany_KodakOpenerAlt-1/original.jpg"

it keeps returning

data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 210 130' /%3E

I've also tried getting the 'srcset' part of the tag but that doesn't even show up in the code.

What can I do in such cases?

ANSWER

Answered 2021-Aug-04 at 07:27

Try selecting using the class name as sugggested by Epis95:

cover_image = card.find('img',class_ = "Image_root__J8Wlz Image_lazy__1w_jB Image_loaded__3uNg2 LandingRiver_image__1ZCUb")['src']

# and if you want the best image quality you could do

# firstly get the srcset
cover_image = card.find('img',class_ = "Image_root__J8Wlz Image_lazy__1w_jB Image_loaded__3uNg2 LandingRiver_image__1ZCUb")['srcset']

# as srcset is a string but the links are seperated using ',' you could split it on the same
cover_image = cover_image.split(',')

# after splitting the best image quality lik is the last one so get the last element of the new list that you have after splitting
cover_image = cover_image[-1]

# you now have a string with 2x as the unwanted part at the last and you could remove that using the slice operation
cover_image = cover_image[:-2]    # slice it upto the third last characterto chop off '2x'

# now you have a string with leading and trailing spaces so strip it to remove any leading or trailing spaces
cover_image = cover_image.strip()
print(cover_image)    # this is the best quality image you can get

Output:

https://cdn.theatlantic.com/thumbor/NL-ZZp6sHiX_1WX2bn9f9o1WWjk=/183x0:2000x1125/420x260/media/img/2021/06/WEL_Tiffany_KodakOpenerAlt-1/original.jpg

QUESTION

How can I create a shorter version of my parallax?

Asked 2021-Apr-10 at 07:11

Basically, I have created a parallax effect with 6 images with media queries for desktop and mobile. The images display fine in desktop mode. However, once I shrink my screen to mobile mode, some of the images just cut off and are not responsive. Because of this, I would like my parallax to only show 4 images on mobile view and the regular 6 images on desktop view. I have tried rearranging my code with my media queries to get this, but I can't seem to figure out a way. How can I do this so only the "viewable" images are only shown on mobile view? Any help is appreciated. Here is my code.

You can play with background-size:contain on your section.module.parallax class for the mobile view. And for displaying images, you can put display: none on images you don't want to show on mobile.

If I understood you well.

Here is the code:

export const App = () => {
    const [newsId, setNewsId] = useState([]);
    useEffect(() => {
        NewsAPI()
         .then(data => JSON.stringify(data))

         return () => {};
     }, []);
     return (<> {newsId.map(data => <NewsCard key={newsId} newsID={data}/>)} </>
};

I tried to map JSON array from newsAPI.

When I simply print out the parameter, I received full JSON data.

But I get the error:

TypeError: newsId.map is not a function

when I tried to map data and order the result by its title.I got full JSON data if I just set {newsId} instead of mapping it.

I have tried {newsId.articles} and {newsId['articles]}, but both return nothing.

You can see the description for JSON function here:

JSON.parse() takes a JSON string and transforms it into a JavaScript object.
JSON.stringify() takes a JavaScript object and transforms it into a JSON string.

In this case the fetch api always return Response Object. This is just an HTTP response, not the actual JSON. To extract the JSON body content from the response, we use the json() method. And after that you can use newsId.articles to get articles list

const [articles, setArticles] = useState([]);
useEffect(() => {
    NewsAPI()
     .then(response => response.json())
     .then(data => setArticles(data.articles));
     return () => {};
 }, []);

 return <>{articles.map(data => <NewsCard key={newsId} newsID={data}/>)}</>

ANSWER

Answered 2021-Feb-19 at 06:52

By default, newsapi shows 20 results per page. You can control that by using pageSize and page params.

Short Answer

The second an image has a src or srcset attribute set it will load the image. You need to use a lazy load library that supports the <picture> element and make sure you haven't set the src or srcset on your <picture> elements.

Long Answer

You have misunderstood a key aspect here. The class="lazyload" and data-src="images/flower3.png" are part of a lazy load solution using JavaScript. You can't just copy these attributes without the related JavaScript code.

With their example (which I assume is this example of lazy loading as you did not link it in your question) there is a script you must include in order to make lazy loading work.

If you look at their example these <img> elements do not have a src attribute set and so they are invalid and will not load the image.

What the script does is look for <img> elements that have a class of lazyload and then look for the data-src attribute.

It then takes whatever is in the data-src attribute and adds that to the src attribute of the image once the image is within the viewport.

This then makes the image valid (as an <img> element must have a src attribute to be valid and actually load the image) and so it loads.

In your example you already have the src set via the srcset attribute in your HTML so the images are loaded instantly, the data-src does nothing in this case.

I am not sure whether the lazy loading library in that example works with <picture> elements (it appears to want you to use an <img> element with data attributes for media queries) so you may want to research a lazy loading library that works with the <picture> element now that you (hopefully) understand why your implementation is not working.

ANSWER

Answered 2021-Jan-06 at 03:20

They are showing up multiple times because you have a nested for loop. Pick one or the other, but not both, and you will end up with one of each image.

{% for photo in photos %} <-- loop one (for the rows)

    <div style="width:100%">
        {% for photo in photos %} <-- loop two (for the columns)

            <div style="float:left; width:200px; height:200px;">
                <img src="{{ photo.photo }}" height="200px" width="200px">

Array map function not return updated items

Asked 2020-Dec-04 at 13:08

I am facing a weird problem (at-least to me) where JS Array method map() is not returning updated array as per map call back logi. I have an the following function

1  handleChange (id){
2     this.setState((prevState)=>{
3      const todos = prevState.myTodos.map(item => {
4        if(item.id === id){
5          //console.log("ITEM.id is ",item.id,"id passed is ",id,"status is ",item.completed)
6          item.completed = !item.completed
7        }
8        //console.log("ITEM.id is ",item.id,"id passed was ",id,"new status is ",item.completed)
9        return item
10      })
11      return {myTodos : todos}
12    })
13  }

In this function I am updating state of App object. Just before the return item in line 8 i can log the output and see that item.completed is changed but when callback returns the item object it is not storing updated item in todos variable.

Any hint could be of great help. Thanks in anticipation

You could try to make your if condition inline so that you don't use return . Something like:

handleChange (id){
    this.setState((prevState)=>{
    const todos = prevState.myTodos.map(item => 
            (item.id === id) ? {...item, completed: !item.completed} : item )
    })
}

Edited: This solution works because it returns a new JS object using the spread syntax {...item, completed: !item.completed}. In turn, this forces a new render call.
