HTML初探

HTML是一种标记语言,是采用标签的形式对纯文本进行标记。然后由解释器进行解释,进而使文本显示出不同的格式。

  • 每个标签必须要有结束标志。HTML中标签的种类以及效果如表一所示。

    text 黑体
    text 斜体

    text 计算机代码文本(没看出有什么区别)
    注释,被忽略
    …… ……
    JavaScript

    JavaScript脚本语言是一种面向浏览器的网页脚本编程语言。脚本语言有以下几个特性:

  • 在客户端执行。完全在用户的计算机上运行,无须经过服务器。

  • 面向对象。具有内置对象,也可以直接操作浏览器对象。

  • 动态变化。可以对用户的输入作出反应,也可以直接对用户输出。

  • 简单易用。JavaScript脚本语言虽然简单,但初学者也能快速掌握。

  • 只能与HTML语言一起使用。要通过浏览器解释执行。

  • 插入javascript

    JavaScript采用如下格式插入在html语言中:

    <script language="JavaScript">//js语句alert("你好");</script>
    Copy after login

    或者直接在地址栏输入:

    javascript:alert(200*75)
    Copy after login

    或者将代码单独保存在 *.js 文件中,在需要时再调用。

    <script language="javascript" src="test.js"></script>
    Copy after login
