{% if theme.selectionCopyright.enable %}
<style>
#selectionCopyright {
position: absolute;
display: none;
background: rgba(244,67,54,.7);
color: #fff;
border-radius: 6px;
box-shadow: none;
border: none;
font-size: 14px;
}
#selectionCopyright a{
color:#fff;
border-color: #fff;
}
#selectionCopyright::before {
content: "";
width: 0;
height: 0;
border-style: solid;
border-width: 6px 8px 6px 0;
border-color: transparent rgba(244,67,54,.7) transparent transparent;
position: absolute;
left: -8px;
top:50%;
transform:translateY(-50%);
}
</style>

<button id="selectionCopyright" disabled="disabled">本文发表于 [<a href="https://blog.enjoytoshare.club/">吴跟强的博客</a>] 分享记得注明来源哟</button>

<script>
window.onload = function() {
function selectText() {
if (document.selection) { //IE浏览器下
return document.selection.createRange().text; //返回选中的文字
} else { //非IE浏览器下
return window.getSelection().toString(); //返回选中的文字
}
}
var content = document.getElementsByTagName("body")[0];
var scTip = document.getElementById('selectionCopyright');

content.onmouseup = function(ev) { //设定一个onmouseup事件
var ev = ev || window.event;
var left = ev.clientX;//获取鼠标相对浏览器可视区域左上角水平距离距离
var top = ev.clientY;//获取鼠标相对浏览器可视区域左上角垂直距离距离
var xScroll = Math.max(document.body.scrollLeft, document.documentElement.scrollLeft);//获取文档水平滚动距离
var yScroll = Math.max(document.body.scrollTop, document.documentElement.scrollTop);//获取文档垂直滚动距离
if (selectText().length > 0) {
setTimeout(function() { //设定一个定时器
scTip.style.display = 'inline-block';
scTip.style.left = left + xScroll + 15 + 'px';//鼠标当前x值
scTip.style.top = top + yScroll - 15 + 'px';//鼠标当前y值
}, 100);
} else {
scTip.style.display = 'none';
}
};

content.onclick = function(ev) {
var ev = ev || window.event;
ev.cancelBubble = true;
};
document.onclick = function() {
scTip.style.display = 'none';
};
};
</script>
{% endif %}

2.2 修改_layout.swig文件

接着在\themes\next\layout\_layout.swig文件最后</body>标签之前添加如下语句:

1
{% include '_third-party/selectionCopyright.swig' %}

2.3 修改_config.yml文件

在主题配置文件_config.yml中加入:

1
2
3
# 鼠标选取文字自动提示版权信息
selectionCopyright:
enable: true

最后在Git Bash里执行hexo s部署,欧克,完成
