Steps to adjust the visibility of an element by modifying its classname

I have this specific class called:

.mapboxgl-ctrl-geocoder {
  font-size: 18px;
  line-height: 24px;
  font-family: "Open Sans", "Helvetica Neue", Arial, Helvetica, sans-serif;
  position: relative;
  background-color: #fff;
  width: 100%;
  min-width: 240px;
  z-index: 1;
  border-radius: 4px;
  transition: width .25s, min-width .25s;
  right: 900px;
  visibility: hidden;
}

The current visibility is set to 'hidden', but I aim to change it to 'visible' when clicked upon:

function search() {
  document.getElementsByClassName('mapboxgl-ctrl-geocoder')[0].style.visibility = "visible";
}

Additionally, this action should be triggered by clicking on the following link:

<a onclick="search()">Search</a>

Despite implementing these steps, the functionality does not seem to be working correctly. I am unsure of what the issue might be. Any suggestions on how to resolve this? Please note that I have confirmed that .mapboxgl-ctrl-geocoder pertains to an element with the class name and not an ID. Thank you for your assistance!

Answer №1

By clicking on the search button, you have the option to add a specific classname to the element.

//--- customized styling ----//
.mapboxgl-ctrl-geocoder {
  font-size: 18px;
  line-height: 24px;
  font-family: "Open Sans", "Helvetica Neue", Arial, Helvetica, sans-serif;
  position: relative;
  background-color: #fff;
  width: 100%;
  min-width: 240px;
  z-index: 1;
  border-radius: 4px;
  transition: width .25s, min-width .25s;
  right: 900px;
  visibility: hidden;
}

.mapboxgl-ctrl-geocoder .show {
  visibility: visible;
}

//----- JavaScript function ------//

function search() {
  let el_mapboxgl = document.getElementsByClassName('mapboxgl-ctrl-geocoder')[0];
  el_mapboxgl.className += " show";
}

Please provide feedback on whether this solution meets your needs.

Answer №2

Include the following CSS rule:

.mapboxgl-ctrl-geocoder .show {
  visibility: visible;
}

Also add this piece of JavaScript code:

function activateGeocoder() {
  let mapboxElement = document.getElementsByClassName('mapboxgl-ctrl-geocoder')[0];
  mapboxElement.className += " show";

Answer №3

As it seems to me, you are currently experiencing a 900px offset to the right. You can adjust this by specifying either 0px or your desired number of pixels in the visibility zone on the left side!
