我在網上找的 兩種解除禁止右鍵、選中、復制的方法
1、直接存到書簽點擊即可

javascript:(function(){var doc=document;var bd=doc.body;bd.onselectstart=bd.oncopy=bd.onpaste=bd.onkeydown=bd.oncontextmenu=bd.onmousemove=bd.onselectstart=bd.ondragstart=doc.onselectstart=doc.oncopy=doc.onpaste=doc.onkeydown=doc.oncontextmenu=null;doc.onselectstart=doc.oncontextmenu=doc.onmousedown=doc.onkeydown=function(){return true};with(document.wrappedJSObject||document){onmouseup=null;onmousedown=null;oncontextmenu=null}var arAllElements=document.getElementsByTagName('*');for(var i=arAllElements.length-1;i>=0;i--){var elmOne=arAllElements;with(elmOne.wrappedJSObject||elmOne){onmouseup=null;onmousedown=null}}alert(unescape('%u5DF2%u4E3A%u4F60%u89E3%u9669%u7F51%u9875%u53F3%u952E%u9650%u5236'));bd.style.webkitUserSelect='auto!important';bd.style.MozUserSelect='text!important';})()

2、直接存到書簽點擊即可

javascript:alert(document.onselectstart = document.oncontextmenu= document.onmousedown = document.onkeydown= function(){return true;});

感謝大佬@ppj975 提供的兩種解除不可粘貼的代碼，如下：
1、直接存到書簽點擊即可

[JavaScript]?純文本查看?復制代碼

1	javascript:(function()%7Bdocument.querySelectorAll('%5Bonpaste%5D').forEach(i%3D%3Ei.attributes.onpaste.value%3D'')%7D)()

2、需要用控制臺運行此代碼

[JavaScript]?純文本查看?復制代碼

1	document.querySelectorAll('[onpaste]').forEach(i=>i.attributes.onpaste.value='')
