site.js

fetch()

Using fetch with modern lambda expressions we make the request by passing in the mandatory path to the api resource being consumed. The fulfilled response is assigned to the variable 'data' and passed into a function called appendData().


appendData()

Here we retrieve a div tag with 'userData' as the id where data will be placed in the html page. Using document.getElementById we assign it to the variable 'allUsers'. We then loop through the response data creating a new div tag to hold each user's name and email address, along with the users unique ID.

After each loop the information is added to a new div, then the div is appended to allUsers via allUsers.appendChild(div) and populated in the html page.


JS in app_details.html

User Details Link

From a very simple standpoint and using vanilla JS, we can send the user id in the url to the app_details.html page. We get the current url using document.location.href and assign it to the varible 'url'.

We split the url at the '?' to get the actual user id and assign it to the vaiable 'data'. Then basically using the same fetch() api process as in the site.js file we populate the html page with details specific to the user.
