Next, we begin to learn the JavaScript language.The JavaScript language is an explanatory language, unlike the compiled language of the ASP. NET, C # language. It is published as an HTML page, meaning it is embedded in an HTML page to run.Here's a simple JavaScript language:The above JavaScript script will display a dialog box and prompt for the "Hello World" string.There are three ways in which JavaScript scripts are embedded in the page:1, File link embedding method. Embed inside the head tag

Objective: Contact with JS since, has not been a good study of a JS book; From today onwards, I will start to learn, organize and share My learning process JS code. In the future published code does not mean that all belong to the original, but many parts will originate from the Internet, of course, will not be less than worry-free script. I hope you'll see. In the forum reprimand, after all, "The face is not elegant"! Posted here, purely to share wit
