当页面失去焦点时改变标题，恢复焦点时恢复标题
将js文件放在主题的static/js文件夹中
在layouts/partials/head.html中添加
{{ if .Site.Params.funnyTitle | default false }}
<script src="/js/funny_title.js"></script>
{{- end -}}
此时在hugo.toml中添加以下内容开启
[params]
# 动态标题
funnyTitle = true
funny_title.js
( function (global) {
var vendorPrefix=getBrowserPrefix();
var eventName=visibilityEvent(vendorPrefix);
document.addEventListener(eventName,visibilityEventCallback);
var titleTime;
var oldTitle=document.title;
function visibilityEventCallback(){
if(document.hidden){
document.title="╭(°A°`)╮ 页面崩溃啦 ~ 快回来看看~ | "+oldTitle;
clearTimeout(titleTime);
}else{
document.title="(ฅ>ω<*ฅ) 噫又好了~";
titleTime = setTimeout(function() {
document.title = oldTitle;
}, 2000);
}
}
// Get Browser-Specifc Prefix
function getBrowserPrefix() {
// Check for the unprefixed property.
if ('hidden' in document) {
return null;
}
// All the possible prefixes.
var browserPrefixes = ['moz', 'ms', 'o', 'webkit'];
for (var i = 0; i < browserPrefixes.length; i++) {
var prefix = browserPrefixes[i] + 'Hidden';
if (prefix in document) {
return browserPrefixes[i];
}
}
// The API is not supported in browser.
return null;
}
// Get Browser Specific Hidden Property
function hiddenProperty(prefix) {
if (prefix) {
return prefix + 'Hidden';
} else {
return 'hidden';
}
}
// Get Browser Specific Visibility State
function visibilityState(prefix) {
if (prefix) {
return prefix + 'VisibilityState';
} else {
return 'visibilityState';
}
}
// Get Browser Specific Event
function visibilityEvent(prefix) {

}
})(this);
