Object, param label and page display PDF file method

Object, param label and page display PDF file method

one, object, param label

HTML <object> Tags

Definitions and usage

Defines an embedded object. Use this element to add multimedia to your XHTML page. This element allows you to specify the data and parameters for inserting objects in an HTML document, as well as the code that can be used to display and manipulate the data.
<object> tags are used to include objects such as images, audio, video, Java applets, ActiveX, PDF, and Flash.
object is designed to replace the IMG and applet elements. This is not true, however, due to vulnerabilities and lack of browser support.
Object support for browsers depends on the object type. Unfortunately, mainstream browsers use different code to load the same object type.
Fortunately, object objects provide a solution. If the object element is not displayed, the code between <object> and </object> is executed. In this way, we are able to nest multiple object elements (each corresponding to one browser).

Instance

To add an object to the HTML code:

<object classid= "clsid:f08df954-8592-11d1-b16a-00c0f0283628" id= "Slider1" width= "height=" > <param name= "BorderStyle" value= "1"/> <param name= "MousePointer" value= "0"/> <param name= "Enabled" value= "1"/> <param name= "Min" value= "0"/> <param name= "Max" value= "ten"/> </object>

Browser support

Almost all major browsers have some support for <object> tags.

The difference between HTML and XHTML

NONE

Tips and Comments:

Note The:<param> label defines the run-time settings for the object.
Note: Do not use <object> labels for images, please use tags instead.

Optional Properties

Property	Value	Describe	Dtd

(a) perfect embedded Quicktime

1, client requirements:

For Windows users and Mac OS X users, install the appropriate version of the QuickTime player. Windows version download Quicktimeinstaller.exe,mac OS X Download QuickTimeinstaller.exe

Windows users can also install storm video and other players with QuickTime decoders and browser plug-ins, such as Storm audio and video.

For Linux and users of Unix systems such as FreeBSD and Solaris, VLC Media Player and its browser plug-ins or MPlayer and their browser plug-ins are required.

2, implementation code:

<object classid= "clsid:02bf25d5-8c17-4b23-bc80-d3488abddc6b" codebase= "http://www.apple.com/qtactivex/ Qtplugin.cab "width=" 420 "height=" 360 "> <param name= "AutoPlay" value= "true"/> <param name= "src" value= "Mov%2f%b2%e2%ca%d4%2emov"/> <embed src= "Mov%2f%b2%e2%ca%d4%2emov" type= "Video/quicktime" autoplay= "true" width= "420" height= "360" > </embed> </object>

3. Main points Analysis:

QuickTime format is easy to embed, like the above to write on it, basically there is nothing to pay attention to the place. The value of the media path SRC, can be a full address, can be a relative address, can be encoded with a URL, you can not encode, QuickTime plug-ins and VLC plug-ins can be the correct support, of course, for the sake of insurance, it is best to use the URL encoding way to write media path.

Although the Video/quicktime type is specified in embed, even the linked media is mp3 still playable. Other types of QuickTime support are not tested, but I think it is possible.

(ii) perfect inline Flash

1, client requirements:

Install the Flash plugin for the browser you are using.

2, implementation code:

<object classid= "clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width= "420" height= ">" <param name= "movie" value= "flash/call to Remember. swf"/> <param name= "Quality" value= "High"/> <embed src= "flash/call to Remember." SWF "quality=" High "type=" Application/x-shockwave-flash "width=" 420 "height=" >< /embed> </object>

3. Main points Analysis:

There seems to be little to say about Flash, because it's very common. Write down here just for easy access, it is dine. Oh.

(iii) allow embedded multimedia to be validated through XHTML

1, Questions:

All of the above code, although the perfect in the various browsers to play well, but there is a drawback, it is that such a page can not be validated through XHTML. The reason is that the embed tag is never a label in the HTML standard, so it is not in XHTML.

2, Solve:

If you don't care if your Web page is up to standard, do it as it is. If you want to pursue perfection, see the following solution:

The following is an example of Flash, which is also useful for other types of multimedia content.

We know that the use of the object tag is recommended by the consortium, but the usage is not Internet Explorer, which uses CLASSID to differentiate between control types, but instead uses type to specify MIME types. Now Mozilla, Firefox and Opera support this use, although the current version of IE support this use, but unfortunately, ie still has bugs, that is only the full download to play. And not all of the cases can be used. White space is also displayed on some IE browsers. Therefore, it is not enough to use the object label usage recommended by the consortium. But we can make some modifications, if the user's browser is IE, we use IE object usage, if it is the other browsers, we use the use of the consortium. So we can have both worlds. Maybe at the moment, you think we should use a script. No, we don't need a script. We only need to use IE unique conditional annotation and CSS can be done. Examples are as follows:

<style type= "Text/css" . Mozilla { Display:block; } </style> <!--[if Ie]> <style type= ' text/css ' . mozilla { Display:none; } </style> <![ endif]--> <object Data= "flashdatei.swf" type= "Application/x-shockwave-flash" height= "275" Width= "256" class= "Mozilla" <param name= "AutoPlay" value= "true" </object> <! --[if ie]> <object classid= "cclsid:d27cdb6e-ae6d-11cf-96b8-444553540000" Width= "256" height= " 275 "" <param name= "src" value= "" flashdatei.swf " </object> <![ endif]-->

You'll find that you're actually replacing embed with object, and the position is removed from IE's object. The SRC attribute in the embed tag becomes the Data property in object. and Firefox and other non-IE browsers because do not know <!–[if ie]> tags, so the part of them as a comment ignored. IE because of the implementation of the contents of the <!–[if ie]>, the Firefox can be identified in the object because the CSS is redefined to be hidden.

How to display the PDF file directly in the Web page

Failed browsers: Firefox, Chrome

3. IFRAME Frame

<iframe src= "test_pdf.pdf" width= "height=" ></iframe>

Browsers passed: 360, Firefox, IE, Chrome

4, with the browser directly to access http://127.0.0.1/test_pdf.pdf (in fact, this is not in the Web)

Browsers passed: 360, Firefox, IE, Chrome

All of the above four methods are under WinXP. (before have encountered the function of upload in Win7 under the condition of failure, so here explain the OS)
