Countdown Timer works on Android and PC but not IOS

[bryanquek]

Hello,

The countdown timer on the site has a “NaaN” error when viewed on iOS devices (right screenshot). However, it looks ok when viewed on Desktop/Android (left screenshot).

Can you advise how to fix please? The code is below. Thank you.

{%- style -%}
  .section-{{ section.id }}-padding {
    padding-top: calc({{ section.settings.padding_top }}px * 0.75);
    padding-bottom: calc({{ section.settings.padding_bottom }}px  * 0.75);
  }

  @media screen and (min-width: 750px) {
    .section-{{ section.id }}-padding {
      padding-top: {{ section.settings.padding_top }}px;
      padding-bottom: {{ section.settings.padding_bottom }}px;
    }
  }
{%- endstyle -%}
<div class="color-{{ section.settings.color_scheme }} gradient">
  <div class="section-{{ section.id }}-padding">

    {%- if section.id == 'template--20243326697784__fd66ea91-20e6-4508-ab6d-1bb16e7dc913' %}

Hi @bryanquek
Tested it on IOS device and it is working fine on my end.
However, you can try updating your script as

document.addEventListener("DOMContentLoaded", function(){ 
//your script here
})

I tried adding the script and viewed again on my iPhone14 device but still has that error.

What iOS phone are you using?

[JasmeetVT14313]

@bryanquek
I have tested it on iPhone 11, iPhone 11 Pro, iPhone 12 as seems to working fine on my end.
Can you share the URL on which you are getting the issue. If you’d like to discuss this more, don’t hesitate to send me a PM.

I tried on a few other physical iPhones as well and all of them still has the ‘NaN’ error.
Could you be trying via the Chrome inspect tool?

[JasmeetVT14313]

Hi @bryanquek
Please share your store URL as I can check better in that case.

Hi @bryanquek
Can you update the date for any future one so that I can check it.
Also, found that you are using countdown as a class in HTML but in script you are trying to get it by ID.

When you create the targetDate…

const targetDate = new Date('{{ section.settings.custom_liquid }} 00:00:00').getTime();

you pass a string value. Different browsers can parse that string differently. The universally recognised format for times is yyyy-mm-ddThh:mm:ss.sssZ, as explained here. By adding “.000” you should solve the problem.

Check this.
