Iframe 只能显示页面的某一部分吗？

Set the iframe to the appropriate width and height and set the scrolling attribute to "no".

If the area you want is not in the top-left portion of the page, you can scroll the content to the appropriate area. Refer to this question:

Scrolling an iframe with javascript?

I believe you'll only be able to scroll it if both pages are on the same domain.

An <iframe> gives you a complete window to work with. The most direct way to do what you want is to have your server give you a complete page that only contains the fragment you want to show.

As an alternative, you could just use a simple <div> and use the jQuery "load" function to load the whole page and pluck out just the section you want:

$('#target-div').load('http://www.example.com/portfolio.php #portfolio-sports');

There may be other things you need to do, and a significant difference is that the content will become part of the main page instead of being segregated into a separate window.

Somehow I fiddled around and some how I got it to work:

<iframe src="http://www.example.com#inside" width="100%" height="100%" align="center" ></iframe>

I think this is the first time this code has been posted so share it

<div style="position: absolute; overflow: hidden; left: 0px; top: 0px; border: solid 2px #555; width:594px; height:332px;">
<div style="overflow: hidden; margin-top: -100px; margin-left: -25px;">
</div>
<iframe src="http://example.com/" scrolling="no" style="height: 490px; border: 0px none; width: 619px; margin-top: -60px; margin-left: -24px; ">
</iframe>
</div>
</div>

Assuming you are using an iframe to import content available to the public but not owned by you into your website, you can always use the page anchor to direct you iframe to load where you want it to.

First you create an iframe with the width and height needed to display the data.

<iframe src="http://www.example.com/page2.html" width="200px" height="100px"></iframe>

Second install addon such as Show Anchors 2 for Firefox and use it to display all the page anchors on the page you would like display in your iframe. Find the anchor point you want your frame to use and copy the anchor location by right clicking on it.

(You can download and install the plugin here => https://addons.mozilla.org/en-us/firefox/addon/show-anchors-2/)

Third use the copied web address with anchor point as your iframe source. When the frame loads, it will show the page starting at the anchor point you specified.

<iframe src="http://www.example.com/page2.html#anchorname_1" width="200px" height="100px"></iframe>

That is the condensed instruction list.

I got this work good for me.

<div style="border: 3px solid rgb(201, 0, 1); overflow: hidden; margin: 15px auto; max-width: 736px;">
<iframe scrolling="no" src="http://www.w3schools.com/css/default.asp" style="border: 0px none; margin-left: -185px; height: 859px; margin-top: -533px; width: 926px;">
</iframe>
</div>

Is this working for you or not let us know.

I needed an iframe that would embed a portion of an external page with a vertical scroll bar, cropping out the navigation menus on the top and left of the page. I was able to do it with some simple HTML and CSS.

HTML

<div id="container">
<iframe id="embed" src="http://www.example.com"></iframe>
</div>

CSS

div#container
{
width:840px;
height:317px;
overflow:scroll;     /* if you don't want a scrollbar, set to hidden */
overflow-x:hidden;   /* hides horizontal scrollbar on newer browsers */


/* resize and min-height are optional, allows user to resize viewable area */
-webkit-resize:vertical;
-moz-resize:vertical;
resize:vertical;
min-height:317px;
}


iframe#embed
{
width:1000px;       /* set this to approximate width of entire page you're embedding */
height:2000px;      /* determines where the bottom of the page cuts off */
margin-left:-183px; /* clipping left side of page */
margin-top:-244px;  /* clipping top of page */
overflow:hidden;


/* resize seems to inherit in at least Firefox */
-webkit-resize:none;
-moz-resize:none;
resize:none;
}

<div style="border: 2px solid #D5CC5A; overflow: hidden; margin: 15px auto; max-width: 575px;">
