jQuery: Replace multiple regex matches with string?

I am trying to use this block of code to replace ALL "12开发者_运维技巧3"'s in a long string with a different number.

   var new_id = new Date().getTime();
    $('#food').after(
      "<div id='123' name='123'> etc etc".replace('123', new_id)
    );

But it's only replacing the first 123 with the new_id. Is there a way to replace all of them?

You need to make it a regex instead of a plain vanilla string and add the /g flag.

"<div id='123' name='123'> etc etc".replace(/123/g, new_id)

replace(/123/g, new_id)

This is regex literal syntax with a global (g) flag.
