<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){
    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;
    }
}
 
//屏蔽复制
____document.oncopy = 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;
    }
}
 
//屏蔽剪切
____document.oncut = 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;
    }
}
 
//屏蔽选中
____document.onselectstart = 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;
    }
}
