javascript - Any way to prevent "deselection" of highlighted text? -

Highlight some text on this webpage, then click anywhere on the document basically. Your selection will disappear.

Is there a way to stop this behavior when a user clicks on a specific element, either by CSS or Javascript?

Example:

  var element = document.getElementById ("foo"); Foo.onclick = function (e) {// some magic is here that prevents discount from}}  

or

  foo.style. PreventDyslect = "true"; Edit: Maybe I can save the selection, then after the "MouseClick" can I restore the selection? There is a way of  store  aselection, and then  search ?  
 Thank you!  
 
 
 "Foremost falls" as well as "E.Provident Default" (FMF) and onMoside work in Safari Does not IE, the only solution for IE, as far as I can tell, is to throw an error.  
 It works in all browsers (but causes an error in IE, because prevention is not a method):  
  // on the 'Test' element Clicking will not deselect the text Var test = document.getElementById ("test"); Test.onmousedown = function (e) {E = E || Window.event; E.preventDefault (); }  
 
 I still want to do this error-free IE, if possible. 
 
 Thank you for Paolo Bergantino for the "Omnoduct" tip.
