Frameset使用教程,使用frameset的好处

frame,是网页开发必须掌握的知识。例如后台架构、局部刷新,页面分割,都是frame的用途表现,尤其是后台页面制作,使用frame会给用户带来非常舒适的使用感受。 frame知识点包括(frameset标签、frame标签、iframe标签)。下面就对其一一介绍。   一、frameset

1. 属性

①border

设置框架的边框粗细。 ②bordercolor 设置框架的边框颜色。 ③frameborder 设置是否显示框架边框。设定值只有0、1;0 表示不要边框,1 表示要显示边框。 ④cols 纵向分割页面。其数值表示方法有三种:“30%、30(或者30px)、*”;数值的个数代表分成的视窗数目且数值之间用“,”隔开。“30%”表示该框架区域占全部浏览器页面区域的30%;“30”表示该区域横向宽度为30像素;“*”表示该区域占用余下页面空间。例如:cols="25%,200,*" 表示将页面分为三部分,左面部分占页面30%,中间横向宽度为200像素,页面余下的作为右面部分。 ⑤rows 横向分割页面。数值表示方法与意义与cols相同。 ⑥framespacing 设置框架与框架间的保留的空白距离。

2. 用例

注意1: cols与rows两属性尽量不要同在一个标签中使用。若要实现下图架构,代码正确写法为: Frameset使用教程                 【即,若想即使用cols又使用rows,可利用frameset嵌套实现】 注意2: 意思是:第一个框架占整个浏览器窗口的40%,剩下的空间平均分配给另外两个框架。 意思是:浏览器窗口等分为四部分。   二、frame 1. 属性 ①name 设置框架名称。此为必须设置的属性。 ②src 设置此框架要显示的网页名称或路径。此为必须设置的属性。 ③scrolling 设置是否要显示滚动条。设定值为auto, yes, no。 ④bordercolor 设置框架的边框颜色。 ⑤frameborder 设置是否显示框架边框。设定值只有0、1;0 表示不要边框,1 表示要显示边框。 ⑥noresize 设置框架大小是否能手动调节。 ⑦marginwidth 设置框架边界和其中内容之间的宽度。 ⑧marginhight 设置框架边界和其中内容之间的高度。 ⑨width 设置框架宽度。 ⑩height 设置框架高度。 2. 用例   三、iframe 是浮动的框架(frame),其常用属性与frame类似,其他的主要有以下(相同的就不列举了) 1. 属性 ①align 设置垂直或水平对齐方式 ②allowTransparency 设置或获取对象是否可为透明。 2. 用例 注意: iframe标签与frameset、frame标签的验证方法不同,是XHTML 1.0 Transitional。且iframe是放在body标签之内,而frameset、frame是放在body标签之外。   四、综合示例 综合示例 <p>对不起,您的浏览器不支持“框架”!</p> 【说明】 标志对也是放在标志对之间,用来在那些不支持框架的浏览器中显示文本或图像信息。在此标志对之间先紧跟标志对,然后才可以使用我们熟悉的任何标志。     最后需要说明一点: 如果将代码按照我以上所写写到VS中报错的话,例如: Frameset使用教程 或者 Frameset使用教程 解决方法如下: 工具→选项→文本编辑器→HTML→验证→Internet Explorer 6.0   好了,通过以上内容,大家再多加练习,就会慢慢熟悉frame的相关知识了,用好了的话你会发现真的挺好。至于frame系列标签的事件方法,一般用的不是非常多,需要的话,大家自己再查吧。【呵呵,其实本人还没有用到过】
