可以通过禁用浏览器的js功能来解除网页禁止粘贴，这里以谷歌浏览器为例。1、同时按住键盘上的“Ctrl”键+“Shift”键+“Del”键打开谷歌浏览器的设置，然后点击页面底部的“高级”按钮：
/iknow-pic.cdn.bcebos.com/d01373f082025aafbd618226f5edab64024f1a8f"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/d01373f082025aafbd618226f5edab64024f1a8f?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/d01373f082025aafbd618226f5edab64024f1a8f"/>
2、点击“高级”按钮之后，在弹出的窗口中向下拉动，然后点击“网站设置”按钮：
/iknow-pic.cdn.bcebos.com/d31b0ef41bd5ad6e229298078fcb39dbb7fd3cf0"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/d31b0ef41bd5ad6e229298078fcb39dbb7fd3cf0?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/d31b0ef41bd5ad6e229298078fcb39dbb7fd3cf0"/>
3、在网站设置中找到“JavaScript”这一项，然后点击一项的按钮：
/iknow-pic.cdn.bcebos.com/9213b07eca8065389db958fe99dda144ac348288"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/9213b07eca8065389db958fe99dda144ac348288?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/9213b07eca8065389db958fe99dda144ac348288"/>
4、在弹出的页面中将JavaScript关闭，这时就解除了网页的禁止粘贴了：
/iknow-pic.cdn.bcebos.com/80cb39dbb6fd5266d5a7c0f9a518972bd507364a"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/80cb39dbb6fd5266d5a7c0f9a518972bd507364a?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/80cb39dbb6fd5266d5a7c0f9a518972bd507364a"/>
