B/S中屏蔽鼠标右键

把如下的JS代码加入页面就可以了

<script type="text/javascript">
    <!--
    var message="";
    ///////////////////////////////////
    function clickIE() {if (document.all) {(message);return false;}}
    function clickNS(e) {if
    (document.layers||(document.getElementById&&!document.all)) {
    if (e.which==2||e.which==3) {(message);return false;}}}
    if (document.layers)
    {document.captureEvents(Event.MOUSEDOWN);document.onmousedown=clickNS;}
    else{document.onmouseup=clickNS;document.oncontextmenu=clickIE;}
    document.oncontextmenu=new Function("return false")
    // -->
    </script>
