I have a donation page using Liquid Shopify. I CANNOT change name="donation[amount_option]"
(I do not have access to that file) so I need code that allows this to stay.
I want to have $250 automatically checked on load
My code
document.querySelector('input[name="donation[amount_option]"][value=250]').checked = true;
<div class="radio-inline donation-v2-amounts padbottommore">
<span>
<input id="donation_amount_25" type="radio" name="donation[amount_option]" class="donation_amount_option" value="25">
<label for="donation_amount_25" class="radio">$25</label>
</span>
<span>
<input id="donation_amount_250" type="radio" name="donation[amount_option]" class="donation_amount_option" value="250">
<label for="donation_amount_250" class="radio">$250</label>
</span>
<span>
<input id="donation_amount_1000" type="radio" name="donation[amount_option]" class="donation_amount_option" value="1000">
<label for="donation_amount_1000" class="radio">$1,000</label>
</span>
</div>

Just add the “checked” keyword to the end of the input.
If you need a pure
js
alternative (in addition to the answer above). You can select by value:document.querySelector('input[value="250"]').checked = true;
EDIT:
In case it isn’t clear, you can use any valid selector such as the id, i.e.:
document.querySelector('#donation_amount_25').checked = true;
.
