Creating A Both Side Radio Wave Animation

Post a Comment
I want a Radar wave animation like this: With a lot of effort using my poor knowledge of Svgs I added the left side of the desired wave and it works fine. but I need some help to

Solution 1:

Using

transform: rotate(180deg);

On a wrapping div will reflect the animation, so you can use it on the right side.

Example:

<div class="radio-wave-container">
      <div class="radio-wave-container content">
        <div class="reflect">
            <svg class="radio-source">
            <use xlink:href="#radio-source"></use>
            </svg>
        </div>
...(etc)

With the following added to the stylesheet:

.reflect {
     transform: rotate(180deg);
}

Solution 2:

Accessing elements wave1..wave6 should be like querySelectorAll:

const wave1 = document.querySelectorAll(".radio-wave-1");
...
const wave6 = document.querySelectorAll(".radio-wave-6");

Because this is a collection.

Next, I applied a for loop, specifying 2 as index to add a class for each wave1..wave6.

Also, I decided to correct your html and css layout. If you want your waves to be in the picture that you showed, then you need to do the following:

Use flex to align with each other. Add this to your css:

.wave-container {
    display: flex;
    justify-content: center;
}

And remove rule margin-right: 50% from .left-wave-container and .right-wave-container selectors.

Now it's done!

function Wave() {
  const waves = document.querySelectorAll(".radio-wave");
  const wave1 = document.querySelectorAll(".radio-wave-1");
  const wave2 = document.querySelectorAll(".radio-wave-2");
  const wave3 = document.querySelectorAll(".radio-wave-3");
  const wave4 = document.querySelectorAll(".radio-wave-4");
  const wave5 = document.querySelectorAll(".radio-wave-5");
  const wave6 = document.querySelectorAll(".radio-wave-6");

  waves.forEach(function(wave) {
    wave.classList.add('add-wave');

    for (var i = 0; i < 2; i++) {    
      wave1[i].classList.add('add-radio-wave-1'); 
      wave2[i].classList.add('add-radio-wave-2');  
      wave3[i].classList.add('add-radio-wave-3'); 
      wave4[i].classList.add('add-radio-wave-4'); 
      wave5[i].classList.add('add-radio-wave-5'); 
      wave6[i].classList.add('add-radio-wave-6');  
    }  
  });
}

setTimeout(() => Wave(), 2000);

  background: black;

    display: flex;
    justify-content: center;
