I want to implement a function, please give me some ideas. .

How should it be achieved.

I use C # .NET to do it.

The function is like this.


On a map, the background can mark information on various locations at will. What the front-end user sees is the map after marking. The user can click on this marked information to enter the corresponding link.


The background can also delete and modify these marked information at will.

Replaced every few days

GoogleEarth??
It's that simple, Winform is easy to handle, the Web won't!

Haha, the problem now is that if you give a picture, you must do it on the picture. And need to be able to modify at any time, delete the annotation information on the picture.


Although it can be achieved with USEMAP, you must manually specify the coordinate information for the picture every time

kind of hard.

Is there any way to automatically obtain the corresponding position coordinates according to the position pulled by the mouse?

It’s not that complicated, what I’m talking about is similar to the hot zone on the picture.

It's just that the hot zone is put in the background user's own operation.

One layer of the map, one layer of labeling, coordinates and connection information, the page output is a superposition of two layers, and the labeling information of the upper layer can be modified in the background. The problem is only in how you store the labeling information.

Are you using C/S or B/S?
Judging that it is B/S, you can use DIV to set, that is, the position of DIV is the position you set in advance, and you can change it every time, but the change is to be saved in the database. The position is obtained by using JS The position of the mouse then determines this coordinate, so that the DIV can have a fixed position when displayed on the customer, and the information is also entered into the database in the background.
