绘图在地图上 [英] Drawing in map

问题描述

我想在地图中定义一些点，并希望通过点击它们加入2点。基本上，功能是识别地图中的位置，并通过单行连接。由于某些原因，我无法使用google map API，并希望使用JavaScript来实现。

提前感谢

解决方案

使用HTML本身不能产生两点之间的一条线（任意角度）。但是这可以通过以下方式实现：

• 使用可用的矢量图形（SVG和VML）的Javascript，谷歌地图实际上使用这种技术一些图形，如路由等。（link）


• HTML5 CANVAS元素（在IE中可以使用excanvas扩展名），（link）


• 只是通过假行作为一个html小元素位置非常接近彼此

I would like to have some points defined in the map and would like to join the 2 points by clicking on them. Basically, the functionality is to identify the locations in the map and connect them by a single line. For some reason, I am not able to use google map API and would like to achieve this using JavaScript.

Thanks in advance, Milan

解决方案

Javascript with use of HTML itself cannot produce a line (in any angle) between two points . But this is possible by:

• using Javascript with some vector graphics available around (SVG and VML), google maps actually use this technology to do some graphic like routing etc. (link)
• HTML5 CANVAS element (with excanvas extension to get this work in IE), (link)
• simply by "fake" lines as a html small elements position very close to each other (link)
