前言

起初添加这个功能,是因为看到leonus和heo都做了这个新功能(新活儿),所以当然不能落后呀,我就马不停蹄的将它实现(抄✍️)了。

预览效果

效果如下图:
鼠标不指向时
鼠标指向时

页面添加按钮元素

找到 themes\butterfly\layout\includes\pagination.pug 文件,并在文件的最后做如下代码添加:

1
2
3
4
5
6
7
8
9
10
11
12
......省略上面无关紧要的代码
else
nav#pagination
.pagination
if is_home()
- options.format = 'page/%d/'
!=paginator(options)
+ if is_home()
+ .toPageGroup
+ input#toPageText(maxlength="3" oninput="value=value.replace(/[^0-9]/g,'')" onkeyup="if (this.value === '0') this.value = ''" title="跳转到指定页面")
+ a#toPageButton(data-pjax-state="" onclick="shine.toPage()")
+ i.fa-solid.fa-angles-right

添加按钮的功能

我们在js文件中添加一段代码(还没做过添加自定义js文件的小伙伴可以看看这篇教程Hexo博客添加自定义css和js文件),使页数跳转按钮的功能可以使用,代码如下:

var shine = {
//跳转按钮
toPage: function() {
console.log("执行跳转");
var e = document.querySelectorAll(".page-number")
, t = parseInt(e[e.length - 1].innerHTML)
, o = document.getElementById("toPageText")
, n = parseInt(o.value);
if (!isNaN(n) && n > 0 && "0" !== ("" + n)[0] && n <= t) {
var a = (n == 1) ? "/" : "/page/" + n + "/";
document.getElementById("toPageButton").href = a
}
},
//监听输入
listenToPageInputPress() {
var e = document.getElementById("toPageText")
, t = document.getElementById("toPageButton");
e && (e.addEventListener("keydown", (e=>{
13 === e.keyCode && (shine.toPage(),
pjax.loadUrl(t.href))
}
)),
e.addEventListener("input", (function() {
"" === e.value || "0" === e.value ? t.classList.remove("haveValue") : t.classList.add("haveValue");
var o = document.querySelectorAll(".page-number")
, n = +o[o.length - 1].innerHTML;
+document.getElementById("toPageText").value > n && (e.value = n)
}
)))
}
}
shine.listenToPageInputPress();

添加按钮的css样式

将下面的按钮css代码复制到你的自定义css文件中,例如custom.css等样式文件(还没做过添加自定义css文件的小伙伴可以看看这篇教程Hexo博客添加自定义css和js文件)。
