Implementing mobile phone positioning based on h5 ajax

亚连Original: 2018-05-24 17:22:362213browse

I have no projects to do recently. I am asking a friend to help me realize the mobile phone positioning function. There are many ways to achieve it. I used h5 and ajax to implement the mobile phone positioning. It is just a demo. I will continue to improve it in the future. I would like to share it with you. Everyone, friends who need it can refer to

. Because my friends need it, I looked at the mobile phone positioning of h5 before, and now I have written a demo and posted it here. Friends who are interested can take a look.

The current version is just a demo. There are still several issues that need to be improved. The questions are as follows:

1. How to send data such as longitude and latitude to the person being positioned so that they cannot see it? to the page.

2, how to bypass or force the person who opens the link to allow the use of positioning (pop-up window).

3. Currently or after obtaining the longitude and latitude, you need to use Google Earth to analyze the user's location (locate and display it through satellite maps). How to simplify this part so that the longitude and latitude of the person being located can automatically generate a map image and import it together? Go to other pages (in short, the targeted person cannot be aware of the fact that he or she is being targeted).
