"Save pages as code" is forbidden

Nowadays, the plagiarism on the Internet is becoming more andmore serious, and his webpage works are often borrowed byothers". In fact, we do not have this trouble, as long as the"add some code or use a special encryption tool on the web pagesource code, images, text encryption, so that others can notmove your web page!

Clever code

Adding a few lines of simple code to the HTML page preventsothers from using the right mouse button and"save as" command.First, shielding the right mouse button

Modify the page label to the following code:

"Body only nselectstart=ncontextmenu=self.event.returnValue=false only" return false"

.

Now click the right mouse button and there won't be anyreaction.

Two, prohibit "save as" command

Add the following code between<body >. . . </body> tag to makethe "save as" command can not be executed smoothly.

< noscr > Pt

< iframe, scr=, *.htm > < /i frame >

< /noscr > Pt

When you add the above code, when the"save as"command is issued,the dialog box will appear when the page is saved.

Using Html Guard

The above method can only protect the security of web pages toa certain extent. If you want to completely prevent others fromcopying, you can use the two methods of code and softwaresimultaneously. The following introduces the use of Html Guardto encrypt the web page.

Html Guard file

Latest edition: 2.3

Software size: 1054KB

Software type: shareware

Applicable system: Win9X/Me/2000/NT/XP

Download address: http://www. skycn.com/soft/6588.htmlStart the software after the installation is complete. Itsoperation interface is mainly composed of five function tags

and settings area (Figure 1) .

First, select the web page file

Click the "Input" tab in the main interface. The selection of"Protect all files a directory in"will encrypt the entire pagefile in the folder. If the files in the sub folder need to beencrypted, the "Include sub directories" item should beselected. If you want to encrypt a single page, you shouldchoose "Protect following HTML files" item, and use the "Add"button to add.

Two, set the output

Use the "Browse" button after the "Output" tag "Copy tofollowing directory" to set the location of encrypted files.Usually we have to choose the "Copy Linked Files" item, so thatwe can copy the linked files of the web page to the outputdirectory. The term"Overwrite existing files" means that theencrypted file overwrites the source file. The author suggestsnot to use this item.

If you don't want to see the output, you can use the "Uploadto server via FTP" item to upload the encrypted file to theserver directly. Click the "FTP-Settings" button, set up theserver address, user name, user password and so on in the pop-updialog box.

Check "Create backup copies of unmodified files beforeoverwriting HTML pages the" under "Backup", which means tocreate a backup before encrypting information into the web page.

In the original folder "Place in the should create a backuporiginal directory".

Three, encryption source code

In the "Source code" page (Figure 2) , there are three ways toencrypt the source code.

1.Encode source code (compiled source code) . When you use thisitem, when someone opens the page with a web editor, it willdisplay garbled code. Because the compiler is based on JavascrPt technology,

So the compiled page must be run in support of Javascr Pt morethan 1 of the browser. If you are worried that people won' t seeyou", then the" Include <noscr Pt > section "is selected, andunder it, the column added that. For example: to view the page,you must have Javascr support Pt more than 1 of the browser.

2.Squeeze source code (compressed source code) . The mainpurpose of this is to remove the empty lines in code and makethe code more compact. In addition to making it difficult forthe pirate to read the source code, it can also reduce the sizeof the page file and effectively reduce the call in time.

3. Insert blank lines (insert blank lines) . The role ofinserting empty lines is also to make it difficult for peopleto find source code. Check the "At the beginning" ("front end")or"At the end (at the end") to determine the location of addingempty lines, and then adjust the value of "Number of lines" todetermine the number of inserted empty lines. In addition, you

can also use the "Insert the following text the top at" itemin the upper end of the web code to add such as "source codenot available (the web code is not available)"and other warninginformation. It is important to note that inserting ablank lineat each time will increase the size of the page file by twobytes.

Four, protect images and text

"Images/Texts options" tab in the following functions: "rightclick menu to help you lock" Lock the menu on the right mousebutton";"Block text selection"no text is selected (the entryinto force of the function can only be above IE4.0 browser) ;"Do not display links in status bar "display links in in thestatus bar;" Deactivate browser`s print function "from thebrowser print function;" Disable Clipboard "from" Disableimage clipboard function; caching in browser banned browserimage cache.

Five, check the results

Click on the "Protect files" button on the right of theinterface to complete the encryption of the web page file (ifyou pop up the warning window and click the "Continue" buttonto continue the work) . Then click the page you want to see inthe "Result" tab, and select "Load in browser" in the expansionitem to see the encrypted effect. Of course, you can also usethe"Path"and"Show source code" commands in the expansion itemto open the encrypted files stored in the folder and view theencrypted source code (Figure 3) .

Now I believe you've basically mastered the software. Quicklyhold up the rights of weapons, protect our legitimate interestswithout infringement.
