HTML iframe和frameset的区别

简介

1.

属性

frameborder {int}:是否显示框架的边框;

src {URL}:指定一个资源(如网页、图片)的uri;

scrolling {boolean}:是否显示框架的滚动条;

width {int}:定义iframe的宽度;

height {int}:定义iframe的高度;

示例

HTML标签演示

注意事项

在"" 内添加内容时,在展示页面不会显示添加的内容。所以还是使用src属性指定一个页面

应用场景

1) 版本升级页面,版本日志过多,可以把升级的信息放到一个iframe里。

2) 富文本编辑框,如博客园的【新建随笔】区域。

标签

frameset 定义一个框架集,包含多个框架,每个框架都有独立的文档。

格式

子项说明

:子框架

:浏览器不支持此框架的时,显示的内容。

属性

frameset 属性:

rows :表示子框架按行的样式布局()。以2个子框架为例:rows="30%,*" ,表示第一个框架占整个页面30%的高度,第二个占剩下的;

cols :表示子框架按列的样式布局()。以2个子框架为例:cols="30%,*" ,表示第一个框架占整个页面30%的长度,第二个占剩下的;

noresize="noresize" :表示不调整子框架的范围。

frame 属性:

src :指向一个资源(如页面、图片等)的URI;

name :指定框架的名称,以便进行框架间的操作。

frameset 演示

注意事项

使用frameset标签时,注意要去掉外层的标签。

子框架间的操作

参照示例代码,frm1更改frm2的子集指向的页面:window.parent.frames["frm2"].location.href = 'b.htm'

应用场景

1) 后台页面的管理,左边显示菜单,右边框架显示详细页面。

2) 功能菜单页面,如https://www.wendangku.net/doc/5813439815.html,

小知识

浏览页面中的框架时,在框架页面内点击右键,会多出框架的信息。

以chrome为例:

不定代词用法总结 1) some, any, no的用法 a. some和any通常用于表示不定数或不定量,修饰复数可数名词或不可数名词。some表示“几个;一些;部 分”,多用于肯定句;而any表示“一些;什么;任何;”,对用于否定句或疑问句中。如: * He asked me some questions. (他问了我几个问题。) * Some of the bread has been eaten. (面包已吃了一些。) * Are there any stamps in this post office (这个邮局里有邮票吗?) * I didn’t have any cigarettes, so I went out to buy some. (我没有香烟了,所以出去买了一些。) b. 刚才我们说some一般用于肯定句而any一般用于否定句和疑问句。但有时也有例外。这要根据句子意思来 看。 * I could not answer some of his questions. (我不能回答他的某些问题。) (some用在否定句中表示“一些;部分”。如果说成:I could not answer any of his questions.意思就变了,它表示“我不能回答他的任何问题。”) * Will you get me some apples on your way back (你回来的路上能给我带一些苹果吗?) (some用在疑问句中大多表示“请求” 或“建议”) * Let me know if you hear any news. (如果你有任何消息请告诉我。) (any用在条件从句中表示“任何”) * “What would you like to drink” “Any will do.” (“你想喝什么?”“哪种都行。”) (any在这里表示“任何”) c. no在句子中作定语,表示否定,意思是“没有;不是”,它可以修饰可数名词的单数和复数形式或不可数名 词。 * There are no letters for you today. (今天没有你的信。) * I have no money at the moment. Could you lend me some (我现在没有钱。你能借我一些吗?) 2) 复合不定代词的用法 a. 不定代词some, any, no与-one, -body, -thing可以组成九个复合代词。它们是: someone anyone no one somebody anybody nobody something anything nothing 这些复合不定代词只有名词的性质,可以作主语、宾语等。 b. 因为some一般用于肯定句,any一般用于否定句或疑问句,no表示完全否定,因此由some, any, no与-one, - body组成的复合代词的用法也一样。 c. 第二部分为-one和-body的复合代词只用于表示人,它们的形式是单数形式,但有时可以用they或them指 代。 * There is someone in your office. Can you hear them talking (你办公室里有人。你听见他们说话了吗?) d. 第二部分为-thing的复合代词只能用于指物。如: * There was something wrong with the car so he had to stopped it. * He looked at me and didn’t say anything. * Nothing can be done to save her life. e. 这些复合不定代词如果有其它的形容词修饰,形容词必须后置。如: * Somebody important has arrived, I’m sure. (important修饰somebody) 3) one和none的用法 不定代词one指代可数名词的单数,即指人,也指物。它的复数形式是ones。在句中可以作主语、宾语、定语等。 * He is not the one who is easily cheated. (one指人) * I’ve made some cakes. Would you like one of them (one指物) * I prefer red roses to white ones. (ones指物) * Are they the ones who moved here a few days ago (ones指人) 4) all, every, each, other, another, either, neither, both a. every只有形容词的性质,在句中作定语。常用于修饰单数的可数名词。表示“每个;各个”,还可以表示“一 切”。 * After the strong wind every flower in the garden was gone. every还可以和-one, -thing, -body构成复合不定代词,即:everyone, everything, everybody。其中,everyone和everybody用于指人,意思一样,都是“每人;大家”,形式上表示单数意思上可以表示单数也可以表示复数。everything用于指物,意思是“每件事;一切”,形式上表示单数意思上可以表示单数也可以表示复数。如:* One can’t have everything. * Everything goes well with me. * The town is so small that everybody knows everybody else. 注意:在使用everyone时要注意和every one相区别。everyone是一个不定代词而every on是一个词组,前者只能指人而后者既可以指人也可以指物。请注意下列例句: * Everyone will be here except Patrick. (everyone 指人) * Every one of the children will get a gift. (every one也指人) *We played several matches against the visitors, but unluckily lost every one. (every one指物)

过去分词用法详解

过去分词的用法 一、构成:规则动词的过去分词是有动词原形+ed构成的,不规则动词则有各自构成。 二、基本特点:过去分词在句子中的基本用法有两点:1.与逻辑主语之间是被动关系 2.表示完成的动作 三、过去分词的用法: 1.作表语:过去分词作表语时,一般同时具备被动与完成的含义 例如:(1)The cup is broken.(2)He is retired. (3)After running,he is tired. 【注意】过去分词作表语时,已经变成形容词性质,主要表示主语的状态(被动完成),而被动语态则表示动作. 例如:(1) The cup was broken by my little sister yesterday. 茶杯是昨天我小妹打碎的.(是被动语态,表示动作) (2)The cup is now broken. 茶杯碎了.(过去分词作表语,表示状态) 【注意】有些动词如interest, bore, worry, surprise, frighten 等通常用其过去分词形式来修饰人,表示“感到……” 用-ing 形式来修饰物,表示“令人……” 例如:The book is interesting and I'm interested in it. 这本书很有趣,我对它很感兴趣. 2.做定语 作定语用的过去分词其逻辑主语就是它所修饰的名词.及物动词的过去分词作定语,既表被动又表完成;不及物动词的过去分词作定语,只表完成. 1)单一过去分词作定语,常置于其所修饰的名词之前,称作前置定语。 例如:We must adapt our thinking to the changed conditions. 我们必须使我们的思想适应改变了的情况. 2)过去分词短语用作定语时,一般置于其所修饰的名词之后,相当于一个定语从句,称作后置定语。 例如:The concert given by their friends was a success.他们朋友举行的音乐会大为成功. 3)过去分词短语有时也可用作非限制性定语,前后常有逗号. 例如:The meeting, attended by over five thousand people, welcomed the great hero. 4)用来修饰人的过去分词有时可以修饰与人有关的表情,面貌,举止行为以及感觉等,这时不能用v-ing形式例如:The boy looked up with a pleased expression. His satisfied look showed that he had passed this exam. 3.作状语 作状语的过去分词在句子中多表示被动和完成两重含义。 1)时间状语:A.当和谓语动词动作同时发生时,一般仅表示被动,可以用when从句代替。 例如:Faced with difficulties,we shouldn’t withdraw for any excuse. B.当表示动作发生在谓语动词之前时,通常既表被动又表完成,可用after从句代替,也可用现在分词的被动完成形式代替。 例如:Caught by the police,the thief lay on the ground,crying and shouting. 2)原因状语:过去分词所表示的动作多有被动和完成两重含义。 例如:Written in a hurry, this article was not so good! 因为写得匆忙,这篇文章不是很好. Welcomed by all the students,we expressed own true thanks to them.被全体同学欢迎,我们表达真挚的感激【注意】有些过去分词因来源于系表结构,作状语时不表被动而表主动.这样的过去分词及短语常见的有: lost (迷路); seated (坐); hidden (躲); stationed (驻扎); lost / absorbed in (沉溺于); born (出身于); dressed in (穿着); tired of (厌烦). 等,这种结构可以改写成一个because引导的主系表结构句子。 例如:Lost / Absorbed in deep thought, he didn't hear the sound.因为沉溺于思考之中,所以他没听到那个声音. Tired of the noise,he decided to move to the country.因厌倦了噪音,他决定搬到农村去。 Dressed in an orange dress,she looked more beautiful than before.穿上橘红色连衣裙,她看起来比以前更美3)条件状语:作条件状语时,一般只表被动含义。相当于if引导的条件状语从句。 例如:Grown in rich soil, these seeds can grow fast. 如果种在肥沃的土壤里,这些种子能长得很快. 4)伴随情况:表示伴随谓语动词发生的另外动作,位于主语之后,用逗号隔开,可以同时表示被动与完成, 例如:The mother ran across the street,followed by her little son. 5)结果状语:表示发生在谓语动词后的动作,位于主句后用都逗号分开,也可以同时表示被动与完成。 例如:He listened to the hero’s story,moved to tears. 【注意】状语从句改成过去分词作状语时有时还可保留连词,构成"连词+过去分词"结构作状语. 例如:When given a medical examination, you should keep calm. 当你做体格检查时要保持镇定.

动词过去分词的用法

现在分词和过去分词主要差别在于:现在分词表示“主动和进行”,过去分词表示“被动和完成”(不及物动词的过去分词不表示被动,只表示完成)。分词可以有自己的状语、宾语或逻辑主语等。表示伴随 1. 分词作状语分词在句子中作状语,可以表示时间、条件、原因、结果(补充说明)、让步、伴随等。分词做状语时,它的逻辑主语与句子的主语一致。作状语的分词相当于一个状语从句。补充说明补充说明 【例】Hearing the news, they all jumped with joy. Using what you know of word stems and word formations, you can make a guess at the meaning of a new word. The students went out of the classroom, laughing and talking. Accompanied by his friend, he went to the railway station. Given better attention, the plants could grow better. He looked tired and depressed, visibly disturbed by the news of his mother's illness. 分词在句子中作状语,使用何种分词,要取决于分词与句子主语的关系:主谓关系用现在分词,动宾或被动关系用过去分词。【例】Not shavings enough hands, we turned to them for help.(we don't have enough hands)Taught by mistakes and setbacks, we have become wiser and handled our affairs better. (we are taught/teach us) Inspired by Leifeng, the people in China worked very hard to achieve their modernization. ____the earth to be flat, many feared that Columbus would fall off the edge.
