Introduction to the method of displaying process progress bar by combining JS and HTML

巴扎黑Original: 2017-09-04 09:27:492661browse

The process progress display bar based on the combination of JS and HTML is very practical and can be used on all major websites. The following editor brings you a detailed explanation of the idea of implementing the process progress display bar by combining JS and HTML. What you need Friends, please refer to it

The effect is as follows:

1. Design ideas

It is divided into the following steps (for reference only)

[Vertical Line]

This is made using the ul list tag, which ensures that it can be added at any time and arranged vertically

[Small Circle]

html tag does not seem to provide a small circle tag. Here, p is added with a radian angle to complete. A square p is added with a radian equal to the length (or width) of p to achieve a small circle. . The tape is even simpler. You can add text directly to p

[Text]

The text must follow the small circle, and must be at the same level as the small circle. Here, position: absolute; set top to complete the layout of the same horizontal height

[Dynamic Effect]

The dynamic effect of the front end, needless to say, must be completed by Javascript, here there are two main events that need to be set, namely ,

Mouse-in eventonmouseover="on_mous_move('info_name_1')"

Mouse-out eventonmouseout="on_mous_out('info_name_1')"

The main logic is to add ❤ and two spaces before and after the text, and delete the added content

[Note]

For js, a space is actually 6 characters " ", so you need to pay attention to

when cutting. . . . That's all, here is the source code of the implementation
