What does ^= do in jQuery (String)?

Question

$('[id^="save_"]').click(function () {});

How is the element being selected using id here?

https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors jQuery's syntax is almost the same. — Kaiido, Oct 30 '17 at 05:22
What does [the jQuery selector documentation](https://api.jquery.com/category/selectors/) tell you? — Some programmer dude, Oct 30 '17 at 05:24

Selects every element whose id attribute value begins with "save_"

As quoted from the jQuery website:

Selects elements that have the specified attribute with a value beginning exactly with a given string.

https://api.jquery.com/attribute-starts-with-selector/

So if you have in your DOM two elements which are #save_address and #save_cart to select both of them by the same prefix save_ you will use $("[id^='save_']")
