屏蔽JS错误和右键

<script language='javascript'>

function resumeerror(){

return true;

}

window.onerror=resumeerror;

</script>

在页面的body内或者HEAD内增加以下代码来屏蔽右键部分功能。

<script type="text/javascript">

document.body.oncontextmenu=function(){return false;};

document.body.ondragstart=function(){return false;};

document.body.onselectstart=function(){return false;};

document.body.onbeforecopy=function(){return false;};

document.body.onselect=function(){document.selection.empty();};

document.body.oncopy=function(){document.selection.empty();};
