Build your entire UI with HTML

Many Shiny apps use a UI object file to build their user interfaces. While this is a fast and convenient way to build user interfaces, some applications will inevitably require more flexiblity. For this type of application, you can define your user interface directly in HTML.

Shiny app of HTML UI. Distribution type and Number of observations as drop downs at the top. A summary of the data and plot of the data below.

The HTML UI application demonstrates defining a Shiny user interface using a standard HTML page rather than a UI object. To run the example type:

 library(shiny) runExample("08_html")

Defining an HTML UI

Many Shiny apps use a UI object file to build their user interfaces. While this is a fast and convenient way to build user interfaces, some applications will inevitably require more flexiblity. For this type of application, you can define your user interface directly in HTML. For such apps, the directory structure looks like this:

application-dir> |-- app.R |-- www |-- index.html

In this example we re-write the front-end of the Tabsets application ( runExample(«06_tabsets») ) using HTML directly. Here is the source code for the new user interface definition:

www/index.html

   html>    src="shared/jquery.js" type="text/javascript">  src="shared/shiny.js" type="text/javascript">  rel="stylesheet" type="text/css" href="shared/shiny.css"/>    HTML UI    Distribution type: />  name="dist">  value="norm">Normal   value="unif">Uniform   value="lnorm">Log-normal   value="exp">Exponential      Number of observations: />  type="number" name="n" value="500" min="1" max="1000" />   Summary of data:   id="summary" class="shiny-text-output">

Plot of data: id=«plot» class=«shiny-plot-output» style=«width: 100%; height: 300px»>

Head of data: id=«table» class=«shiny-html-output»>

There are few things to point out regarding how Shiny binds HTML elements back to inputs and outputs:

  • HTML form elements (in this case a select list and a number input) are bound to input slots using their name attribute.
  • Output is rendered into HTML elements based on matching their id attribute to an output slot and by specifying the requisite css class for the element (in this case either shiny-text-output, shiny-plot-output, or shiny-html-output).

With this technique you can create highly customized user interfaces using whatever HTML, CSS, and JavaScript you like.

Server function

All of the changes from the original Tabsets application were to the user interface, the server script remains the same:

 # Define server logic for random distribution app ---- server  function(input, output)  # Reactive expression to generate the requested distribution ---- # This is called whenever the inputs change. The output functions # defined below then use the value computed from this expression d  reactive(  dist  switch(input$dist, norm = rnorm, unif = runif, lnorm = rlnorm, exp = rexp, rnorm) dist(input$n) >) # Generate a plot of the data ---- # Also uses the inputs to build the plot label. Note that the # dependencies on the inputs and the data reactive expression are # both tracked, and all expressions are called in the sequence # implied by the dependency graph. output$plot  renderPlot(  dist  input$dist n  input$n hist(d(), main = paste("r", dist, "(", n, ")", sep = ""), col = "#007bc2", border = "white") >) # Generate a summary of the data ---- output$summary  renderPrint(  summary(d()) >) # Generate an HTML table view of the head of the data ---- output$table  renderTable(  head(data.frame(x = d())) >) >

Building the Shiny app object

We end the app.R file with a call to the shinyApp function to build the Shiny app object using the UI and server components we defined above.

 shinyApp(ui = htmlTemplate("www/index.html"), server)

Interactive HTML user interfaces

HTML form

  • in this section, we’ll learn how to make user interface controls (buttons, checkboxes, text fields, etc.) in HTML
  • controls are often used in HTML forms (seen later)
  • Javascript is integral to interactivity aspect of controls (event handlers)

Document Object Model (DOM)

DOM

  • a representation of the current web page as a set of Javascript objects
  • allows you to view/modify page elements in script code
  • DOM tutorial

Global DOM objects

  • window : the browser window
  • navigator : info about the web browser you’re using
  • screen : info about the screen area occupied by the browser
  • history : list of pages the user has visited
  • document : current HTML page

Recall: event handlers

onclick="myFunction();">Click me!

Click me!

  • HTML elements have special attributes called events
  • Javascript functions can be set as event handlers
    • when you interact with the element, the function will execute
    • an example of event-driven programming
    • onabort , onblur , onchange , onclick , ondblclick , onerror , onfocus , onkeydown , onkeypress , onkeyup , onload , onmousedown , onmousemove , onmouseout , onmouseover , onmouseup , onreset , onresize , onselect , onsubmit , onunload

    document object and getElementById 

    onclick="makeRed();">Sell
     
    id="announce">Get it while it's hot!
     
    function makeRed() < var para = document.getElementById("announce"); para.style.color = "red"; >

    Sell

    • document object’s getElementById method returns an object representing the HTML element with the given id attribute ( null if not found)
    • DOM objects for all HTML elements contain the following properties:
      • className , id , style , title

      DOM style property

      function enlarge(id) < var element = document.getElementById(id); element.style.fontSize = "42pt"; >
      • style property represents the combined styles that apply to this element
      • contains identical properties to the style properties set in CSS, except that names are changed from hyphenated to capitalized
        • examples: backgroundColor , borderLeftWidth , fontFamily

        Buttons:
        • button’s text appears inside button tag
        • JS onclick event handler specifies button’s behavior

        The DOM innerHTML property

         
        function myFunction(text) < var p = document.getElementById("target"); p.innerHTML = text; >

        This text will be replaced.

        • innerHTML refers to the HTML text inside of an element:

          this is the innerHTML of the p tag

        • event handler can modify the innerHTML of another element

        Another example

        function addText() < var button = document.getElementById("b1"); button.innerHTML += " narf"; >

        Text boxes: (DOM)

        • initial text placed inside textarea tag (optional) rows and cols attributes specify textarea size in characters —>
        • optional readonly attribute means text cannot be modified
        • DOM properties: disabled , read O nly , value
          • NOTE: get/set area’s text using value , NOT innerHTML

          Practice problem: Shuffle

          • Write the HTML and Javascript code to shuffle the lines of text within a text area whenever a Shuffle button is clicked.
          • shuffling algorithms
          • option element represents each choice
          • select optional attributes: disabled , multiple , size
          • attach onchange handler to select to cause behavior on each selection

          Using for lists
          • DOM properties: disabled , length , multiple , name , selectedIndex , size , value (selected item text)
          • DOM methods: add( option , index ) , remove( index )

          Option groups:

          Input fields:

          input type="text" /> 
          input type="password" size="12" />
          • creates many different types of input controls, depending on its type attribute
          • always empty; contains attributes only
          • attributes: accept , alt , disabled , maxlength , name , readonly , size , src , type , value
          • DOM properties for type=»text» and type=»password» : disabled , maxLength , readOnly , size , value (text in field)

          Radio buttons (DOM)

          type="radio" name="creditcards" />  type="radio" name="creditcards" />  type="radio" name="creditcards" />
          • grouped by (required) name attribute
          • button’s text is a label element with for attribute set to button’s id
          • DOM properties: checked , defaultChecked , disabled

          Checkboxes (DOM)

          type="checkbox" name="toppings" value="lettuce" />  type="checkbox" name="toppings" value="tomato" />  type="checkbox" name="toppings" value="pickles" />
          • name attribute is required
          • use checked=»checked» attribute in HTML to initially check the box
          • DOM properties: checked (Boolean), defaultChecked , disabled
          • name attribute is required
          • DOM properties: accept (comma-separated list of MIME types this box accepts), disabled , name , value (text in box)

          Grouping input: ,

            Credit cards:

          Practice problem: Colored text

          • Write the HTML and Javascript code to present a text area and three on/off options for red, green, and blue.
          • When the user checks each box, it will add or remove that color from the text area’s text.
