Enabling blocked text selection using JavaScript

Question

I recently came across a website that disabled text selection, preventing anyone from easily copying and pasting text. I have a bookmarklet that disables similar attempts to block context menus using JavaScript, and I'm wondering if it would be possible to do something similar for text selection.

function disableSelection(target){ if (typeof target.onselectstart!="undefined") //For IE     target.onselectstart=function(){return false} else if (typeof target.style.MozUserSelect!="undefined") //For Firefox     target.style.MozUserSelect="none" else //All other route (For Opera)     target.onmousedown=function(){return false} target.style.cursor = "default" } 

Elsewhere the function is called with disableSelection(document.body).

The solution from my context menu bookmarklet is also probably necessary:

javascript:void(document.onmousedown=null); void(document.onclick=null); void(document.oncontextmenu=null) 

Finally, I had seen elsewhere on StackOverflow that CSS could also be used:

-webkit-user-select: none; -khtml-user-select: none; -moz-user-select: none; -o-user-select: none; user-select: none; 

Is there a method to fight all of these at once and end this tyranny over my browser? How would I both enable MozUserSelect/SelectStart for all elements and set the CSS properties?

Check out the Enable All Text Selection bookmarklet by Alan Hogan. The only issue with the bookmarklet is that it does not handle frames/iframes (that's a browser security thing so it's unlikely something can be done about it).

As an added bonus, it also enables the mouse right-click event on pages that block it.

Create a bookmark (e.g. by dragging the icon to the left of the URL for any page to your bookmarks bar), right-click and select Edit, rename to something meaningful, and insert the following code in the URL field:

javascript:(function(){function%20allowTextSelection(){window.console&&console.log('allowTextSelection');var%20style=document.createElement('style');style.type='text/css';style.innerHTML='*,p,div{user-select:text%20!important;-moz-user-select:text%20!important;-webkit-user-select:text%20!important;}';document.head.appendChild(style);var%20elArray=document.body.getElementsByTagName('*');for(var%20i=0;i<elArray.length;i++){var%20el=elArray[i];el.onselectstart=el.ondragstart=el.ondrag=el.oncontextmenu=el.onmousedown=el.onmouseup=function(){return%20true};if(el%20instanceof%20HTMLInputElement&&['text','password','email','number','tel','url'].indexOf(el.type.toLowerCase())>-1){el.removeAttribute('disabled');el.onkeydown=el.onkeyup=function(){return%20true};}}}allowTextSelection();})();
