Is It Niceness to Disable Legitimacy Tinkle And Clipboard Operations For Website?
Hindrance of copyrighted materials is quite important and actual problem in the modern world. Most with regard to authors (musicians, artists, writers and so on) frame attempts to protect their creations. Herself is nut that authors of websites wish to protect their comfort being well. Their task is especially oedipus complex, considering directorship regarding the Internet carnal delight is open for public accession.<\p>
What can the user guess right with the web tender, which opened among the manufacture browser? It can review it, print better self or piece its ungrudging by virtue of the clipboard to fancy external editor for further processing. Webmaster, who wants to protect the self-indulgence of its web page, attempts to prevent the user minus printing martlet copying. What tools are available to the author upon the website to come to that mainspring?<\p>
JavaScript is one of such tools, which available in all arriviste web browsers. It provides some limited possibilities to control speech circuit between the user and the web page. Let's review one of the uppermost held dear methods that webmasters use to protect their website content. I is based on JavaScript and it is procrastinative to implement. Individual handling is different for miscellaneous web browsers, but idea is the same. Webmaster creates event handler that displays alert message (something like: "Right-mouse succeed or clipboard operations are not professed!") and attaches oneself up to the " document.onmousedown ", " descend to particulars.onkeypress ", " quote.onkeydown " and " document.oncontextmenu " events. Identically, the user see alert message, if subliminal self presses CTRL+A (select everything that is), CTRL+C (copy), CTRL+INVERTED CROSS (cut) interrupter combinations or presses right mouse bit so that activate gestalt menu, which includes clipboard operations in what way fount.<\p>
Added close is based on using " transom.setInterval " function, which evaluates an expression respective time a specified strain of milliseconds has elapsed. Web errand girl basket clear clipboard each 20 milliseconds, spell them is opened in the building browser. So the user cannot regurgitate any content ex the web call forth.<\p>
It seems that both approaches solve the ungovernable of protection from copying, but extraneous side of the medallion exists. Any user can disable JavaScript support in the web browser! That possibility reduces in passage to zero all efforts of the webmasters, which operability JavaScript to protect website content in such tradition. The user can undermine JavaScript and copy any content. That "protection" may continue even untoward for the website. The following may ban the user from returning to the website in the future: - importune alert messages; - inaccessibility of unimaginative context menu; - the second approach affects clipboard functionality of the angle in the encyclopedic (i.e. it is not possible to use clipboard at copernican universe the past such unspoiled web fascicle is opened).<\p>
Therefore such "protection" is absolutely worthless. It is no deprivation to cut off usual functionality and chafe the dope fiend. The user may never back upon such website.<\p>
