    <script type="text/javascript">
    //屏蔽右键菜单
    document.oncontextmenu = function (event){
    if(window.event){
    event = window.event;
    }try{
    var the = event.srcElement;
    if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
    return false;
    }
    return true;
    }catch (e){
    return false;
    }
    }
    //屏蔽粘贴
    document.onpaste = function (event){
    event = window.event;
    }try{
    var the = event.srcElement;
    if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
    return false;
    }
    return true;
    }catch (e){
    return false;
    }
    }
    //屏蔽复制
    document.oncopy = function (event){
    if(window.event){
    event = window.event;
    }try{
    var the = event.srcElement;

    return false;
    }
    return true;
    }catch (e){
    return false;
