I have created a custom "Send an Email" button using the URL below for case Object. Is there a way to add to this to Auto-populate the "To" field to be the email address from Custom object?

&p24= test@email.com

enter image description here

You can use JS location.search to access the url query and inject it into your text value

If your url is /page.htm?x=y, you can use the following code to set the value of a text field.

var params = getUrlParams();
document.getElementById('myTextFieldId').value = params.x;
  • Thanks @Adamo, I need populate multiple email address to TO field not from url.
