js复制内容加版权声明代码
当别人复制你的文章内容时,会在文章末尾自动添加一个版权声明。网络版权意识薄弱,这个是君子做法,如果真要抄你的文章,声明再多都没用,就像我的网站底部声明一样,几乎是一个摆设,我也看开了。文章保留所有权利,如果你复制我的文章,没有按照我的声明,说不定哪天我心情好,就会找你聊聊天了……
- $("body").on('copy', function (e) {
- if (typeof window.getSelection == "undefined") return; //IE8 or earlier...
-
- var body_element = document.getElementsByTagName('body')[0];
- var selection = window.getSelection();
-
- //if the selection is short let's not annoy our users
- if (("" + selection).length < 30) return;
- //create a div outside of the visible area
- //and fill it with the selected text
- var newdiv = document.createElement('div');
- newdiv.style.position = 'absolute';
- newdiv.style.left = '-99999px';
- body_element.appendChild(newdiv);
- newdiv.appendChild(selection.getRangeAt(0).cloneContents());
-
- //we need a <pre> tag workaround
- //otherwise the text inside "pre" loses all the line breaks!
- if (selection.getRangeAt(0).commonAncestorContainer.nodeName == "PRE") {
- newdiv.innerHTML = "<pre>" + newdiv.innerHTML + "</pre>";
- }
-
- newdiv.innerHTML += "<br /><br />原文: <a href='"
- + document.location.href + "'>"
- + document.location.href + "</a> © caibaojian.com";
-
- selection.selectAllChildren(newdiv);
- window.setTimeout(function () { body_element.removeChild(newdiv); }, 200);
- });
