HomeWeb Front-endHTML TutorialHow to introduce external pages in HTML (iframe tag method)

During page layout, some external pages will be introduced into HTML. This article will tell you how to introduce the iframe tag method of external pages into HTML. Friends in need can refer to it, I hope it is useful to you.

First of all, the easiest thing to think of is to use iframe. Although html5 has abolished frame, it still retains iframe. We can still use it. iframe has a frameboder attribute. Set the attribute value to 0 or no. Remove the borders of the iframe. Then set scrolling to no. This is completely doable, but remember to run it in a server environment.

 var frame = document.getElementsByTageName("iframe")[0];
    frame.contentWindow.document.XXX方法,
    如frame.contentWindow.document.querySelector("#btn");//获取iframe中Id为btn的节点.123

Because I have no experience using iframe to introduce the header before, considering that the header usually has another function besides jumping, it should be positioning. When the page is long, click to accurately locate a certain point. at. The jump of the page has no effect if introduced using iframe, but what about the anchor point? You need to try this to know.

Here, add some knowledge about anchor points:

Anchor points can jump to the corresponding position of the current page, and can also jump to the corresponding position of other pages.

There are two ways to implement anchor points, one is to use the name attribute of a tag, and the other is to use the Id attribute of the tag.

The details are as follows:

a. Use the name attribute of the a tag

<a href = "#detail">详情</a> 
<a name = "detail"></a>12

Click "Details" and jump to Position.

b. Use the id attribute of the tag

<a href = "#detail">详情</a>
<div id = "detail"></div>12

Click "Details" to jump to the location of

.

Use The anchor point often fails when using a name, so it is recommended to use id to bind the anchor point.

Getting back to the subject, after introducing iframe, can we locate the corresponding position by clicking on the element in the iframe? Here, we use iframe to introduce head.html, which is also my original purpose.

So what we want to achieve is: click on the a tag of the iframe and locate the corresponding position of the main Html. Through implementation, we found that it cannot be achieved simply through html, but it can be done with the help of JS.

<!doctype html>
<html>
    <head>
    <!--网站编码格式,UTF-8 国际编码,GBK或 gb2312 中文编码-->
        <meta http-equiv="content-type" content="text/html;charset=utf-8" />
        <meta name="Keywords" content="关键词一,关键词二">
        <meta name="Description" content="网站描述内容">
        <meta name="Author" content="Yvette Lau">
        <title>Document</title>
        <!--css js 文件的引入-->
        <style>
            #leftFrame{display:block;}
        </style>
    </head>
    <body>          
        <div><img  src="/static/imghwm/default1.png"  data-src="test1.html"  class="lazy"  src = "img/photo1.jpg"    style="max-width:90%"/ alt="How to introduce external pages in HTML (iframe tag method)" ></div>      
        <iframe  height= "100px" name="leftFrame" scrolling="No"  noresize="noresize"  id="leftFrame"></iframe>
        <div><img  src = "img/photo2.jpg"     style="max-width:90%"/ alt="How to introduce external pages in HTML (iframe tag method)" ></div>
        <div><img  src = "img/photo3.jpg"    style="max-width:90%" / alt="How to introduce external pages in HTML (iframe tag method)" ></div>
        <p id = "buttom">detail</p>
    </body>
</html>
<script>
    window.onload = function(){
        var iframe = document.querySelector("#leftFrame");
        var bot = iframe.contentWindow.document.querySelector("#bot");
        var top = iframe.contentWindow.document.querySelector("#top");
        bot.onclick = function(){
            document.body.scrollTop = document.body.offsetHeight;
        };
        top.onclick = function(){
            document.body.scrollTop = 0;
        };
    };
</script>

There are elements with IDs bot and top in the iframe. Positioning is achieved through JS.

In the main page, the document in the iframe can be returned as an HTML object through iframe.contentWindow, and the returned object can be processed through all standard DOM methods.

In the iframe page, locate the parent html through parent, and you can locate the top-level html through top.

When calling between iframes at the same level, you need to locate the parent html first, and then locate iframe.

Add some knowledge about anchor points. The key function is the #detail added after the connection address (detail only refers to it in general). If the current url is localhost:8080/index.html. Then After the anchor point, the url should be localhost:8080/index.html#detail

The URL address has a "#" identifier at the end, indicating that it needs to jump to the corresponding location. #idName, the browser will find a tag that matches the characteristics of "#idName" on the page. If the character following "#" in the URL cannot be found in the text, if it is the current page, then it will not jump. If it jumps from another page, the top of the page will be displayed.

Go back to the top of the page. In addition to setting the scrollTop of the body through JS (0 returns to the top, sets it to the height of the body, and jumps to the top), another method is Back to top.
