You can use the getDirection () method of RasterMap to query the path. Similar to the query address, the path query result notifies the application through the callback function, the following example returns the path from Nanjing to Beijing. The returned results are stored in MapDirection. MapDirection contains detailed information about the path, including each step, length, time, and direction of the path.

This article brings the content is about the example analysis: HTML5 front-end performance test (graphics and text), there is a certain reference value, there is a need for friends to refer to, I hope you have some help. H5 page is flexible, lightweight, and has cross-platform features, there are many application scenarios in the business. But at the same time compared to APP,H5 performance is always infer

A good example is found in reading a book about the development of a HTML5 game, which allows for a more in-depth understanding of object-oriented development. This object is implemented by drawing an image from a CSS sprite into the canvas. First create a Spritesheet object with the following code:var spritesheet = new function () {This.map = {};this.load = func

This article mainly introduces the code example of using HTML5Canvas to implement the rose curve and the heart-shaped pattern. For more information, see : Tip:Copy the code to an html file and save it. Open it and you will see the effect. Implementation Code: The Code is as follows: HTML5 Demo Your browser does not support the canvas element
