Update the Height of an Element Dynamically

JavaScript
#1

This code passed just one test. I don’t know what went wrong

Your code so far


<style>
  .bar {
    width: 25px;
    height: 100px;
    display: inline-block;
    background-color: blue;
  }
</style>
<body>
  <script>
    const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];
    
    d3.select("body").selectAll("div")
      .data(dataset)
      .enter()
      .append("div")
      .attr("class", "bar")
      // Add your code below this line
      .style("height", d => d+'px'  ); // Maybe something is wrong here 
      
      
      // Add your code above this line
  </script>
</body>

I tried this and it worked:
.style(“height”, (d) => ${d}px );

Here, I’ve used string literals to add ‘px’ to the value of d.
Hope this helps :slight_smile:

I tried it but this is not working

#4

Try resetting the code and then try again.

#5

Still not working.:disappointed:

#6

mine neither. is this ${d} syntax supposed to be working in D3? I know this is a jQuery syntax though.

#7

It seems to work with

.style("height", (d) => d + "px" );
