如何 Datalayer.push 一个复选框变量

Question

I was hoping if somebody could help me figure out how to get datalayer.push data from checkboxes the user has selected on a form during submission. The form has many fields but I only want the checkboxes that have been selected.

Answer 1

You need to check when you are calling dataLayer.push

If the function is called after document.ready or on change or on form submit-event. As the case could be that the value of the checkbox is undefined at the time of dataLayer.push function call.

To get the value of checked checkbox use: $('.form-check__input:checked').serialize();
