封滑鼠右鍵、複製(只防君子)

這個只是一個簡單的JavaScript，目的在防止使用者按滑鼠右鍵、複製文章。 不過，當然使用者如果有心的話，還是防不住的。下列就只寫 JavaScript code，不解釋了.. 反正看的懂的就看的懂..看不懂的還是看不懂..

function clickExplorer() {
    if( document.all ) {
     //alert('All materials on this site are copyright protected.');
    }
    return false;
}

function clickOther(e) {
    if( document.layers || ( document.getElementById && !document.all ) ) {
     if ( e.which == 2 || e.which == 3 ) {
            //alert('All materials on this site are copyright protected.');
     return false;
 }
    }
}
if( document.layers ) {
    document.captureEvents( Event.MOUSEDOWN );
    document.onmousedown=clickOther;
} else {
    document.onmouseup = clickOther;
    document.oncontextmenu = clickExplorer;
}
window.addEvent('domready', function() {document.body.oncopy = function() {
//alert('All materials on this site are copyright protected.'); 
return false;}});
if ( typeof(document.onselectstart) != 'undefined' ) {
    document.onselectstart = function() { return false };
}
document.ondragstart = function(){ return false }
