Let me introduce the concept of vector graph:
Vector graphs use lines and curves to describe graphics, elements of which are points, lines, rectangles, polygons, circles, and arcs, all of which are computed by mathematical formulas. For example, a flower vector graphic is actually formed by the outline of the line lines, the color of the outer frame and the color of the outer frame to determine the color of the flower display.
SVG,VML, HTML5 Canvas These three techniques are plotted in vector

communication layer, that is to say, calling Web Service in JavaScript to obtain data has become an extremely simple thing-its elegance has even left us unconvinced: Can Ajax programs be written so easily?
Next, let's use a simple example program to understand how to use JavaScript to call Web Service asynchronously in ASP. net ajax applications. For the purpose of demonstration, the function of the progra

Note Although the Web development model may be the same, there are still many web developers who think they have created a new model. They put it on their site as a patent for an uncertain attribution, and there is no new thing in fact.

What users need is simply to guide the accessibility tools, such as search engines, site images, site indexes, or help systems that lead them to the goal. These navigation systems will be discussed in detail in chapters 7th and 8th.

Since the University, I have determined my programming language direction: C/C ++. I have been working for more than six years now, and have basically been working on C/C ++ projects. Among them, I have had more than half a year of java/web development experience, allowing myself not only to have a great deal of technical expansion, but also to gain a very precious wealth in thinking.
