Displaying elements of array in Pug template is a key task for

As a newcomer to the Jade/Pug template engine used in Express, I am faced with a challenge. I need to display the name property of each object within an associative array that is passed as a parameter to my pug template from an express route module.

I have attempted various methods, such as:

  each element in listOfElements
      p #{element.name}

where listOfElements is the parameter name being passed

Unfortunately, I have not achieved the desired outcome so far.

UPDATE

Currently, I am referring to the documentation which only provides an example using UL tags (not suitable for my case).

Following the documentation's guidelines, I have tried the following approach:

ul
each element in listOfElements
    li = element.name

However, the rendered page displays a list where each bullet point contains the text " = element.name"

Answer №1

According to the information provided on the Pug website regarding iterations, you can receive buffered code by adding an = immediately after the tag name. The necessary documentation is available here. Therefore, in your second try, the following code will function correctly:

ul
each element in listOfElements
    li= element.name

On the other hand, for the first attempt, I experimented with the subsequent code and it generated the anticipated result (as displayed below the snippet):

ul
  each val in [{1:'a'}, {1:2}, {1:3}, {1:4}, {1:5}]
    li #{val[1]}

This produces:

<ul>
  <li>a</li>
  <li>2</li>
  <li>3</li>
  <li>4</li>
  <li>5</li>
</ul>
