Differences between jQuerybefore and insertBefore

The following small series will introduce the differences between jQuerybefore and insertBefore. I think this is quite good. Now I will share it with you and give you a reference. Let's take a look at the simple editor. Using before and insertBefore in jQuery can insert the specified content before the specified element. There are differences in writing the content.

Let's take a look at an example:

In

P1

Insert

ToInsertContent

Implementation:

$ ('

ToInsertContent

'). InsertBefore ($ ('. p1 '));

Or

$ ('. P1'). before ('

ToInsertContent

');

Result:

ToInsertContent

P1

Incorrect syntax:

$ ('

ToInsertContent

'). Before ($ ('. p1 '));

Result:

Instead of inserting elements before p1, p1 will be deleted.

Summary:

Before is inserted before which element, followed by the inserted content Element

InsertBefore is preceded by the inserted content element, followed by the inserted element

It cannot be reversed.
