FastJump.js
智能摘要
获取中……
110行写了个小玩意,可以像sw那样离线缓存,和Pjax类似,不过用了自主缓存,fetch做请求,算了上代码吧:
self.CACHE_NAME = 'FastJumpCache'; // 默认的存储名称
self.db = {
read: (key) => {
return new Promise((resolve, reject) => {
caches.match(new Request(`https://LOCALCACHE/${encodeURIComponent(key)}`)).then(function (res) {
res.text().then(text => resolve(text));
}).catch(() => {
resolve(null);
});
})
}, write: (key, value) => {
return new Promise((resolve, reject) => {
caches.open(CACHE_NAME).then(function (cache) {
cache.put(new Request(`https://LOCALCACHE/${encodeURIComponent(key)}`), new Response(value));
resolve();
}).catch(() => {
reject();
});
});
}
}
document.addEventListener('DOMContentLoaded', function () {
self.db.read(window.location.href).then(function (d) {
if (!d) {
fetch(window.location.href).then(function (d) {
if (d.headers.get('content-type') === 'text/html') {
d.text().then(function (b) {
self.db.write(window.location.href, b)
})
}
})
}
});
});
document.addEventListener('DOMContentLoaded', function () {
setInterval(function () {
var doms = document.querySelectorAll('a[href]');
Array.prototype.forEach.call(doms, function (dom) {
if (dom.href && dom.href.indexOf(window.location.origin) === 0) {
dom.onclick = function () {
history.pushState({}, '', dom.href);
self.db.read(dom.href).then(function (d) {
if (d) {
console.clear();
document.open();
try {
document.write(d);
let Event_timerun = window.setInterval(function () {
if (document.body&&document.body.innerHTML) {
let Event = new CustomEvent('onload')
document.dispatchEvent(Event);
window.dispatchEvent(Event);
Event = new CustomEvent('DOMContentLoaded')
document.dispatchEvent(Event);
window.dispatchEvent(Event);
window.clearInterval(Event_timerun)
}
},500)
fetch(dom.href).then(function (d) {
if (d.headers.get('content-type') === 'text/html') {
d.text().then(function (b) {
self.db.write(window.location.href, b)
})
}
})
} catch (e) {
}
} else {
fetch(dom.href).then(function (d) {
if (d.headers.get('content-type') === 'text/html') {
d.text().then(function (b) {
console.clear();
document.open();
try {
document.write(b)
let Event_timerun = window.setInterval(function () {
if (document.body&&document.body.innerHTML) {
let Event = new CustomEvent('onload')
document.dispatchEvent(Event);
window.dispatchEvent(Event);
Event = new CustomEvent('DOMContentLoaded')
document.dispatchEvent(Event);
window.dispatchEvent(Event);
window.clearInterval(Event_timerun)
}
},500)
} catch (e) {
}
self.db.write(dom.href, b)
}).catch(function (e) {
window.location.href = dom.href
})
}
}).catch(function (e) {
window.location.href = dom.href
})
}
}).catch(function (e) {
window.location.href = dom.href
})
return false;
}
}
});
}, 500)
});
注意不能与Pjax一起使用!!
鄙人水平有限,请斧正
有不少Bug,仅供测试,不可以在线上环境使用
