我是VueJS的新手,除了分页之外,几乎所有东西都在工作。实际上,我的警告为零。控制台中出现的唯一内容是“ [HMR]等待来自WDS的更新信号... log.js?4244:23”,然后在下一行加上“>”。
话虽如此,但分页显示的页面数正确-给定数据来自JSON,但我不知道如何将分页连接到UL或应用程序。
至少当出现错误时,我可以弄清楚。感谢您的帮助,并在此先感谢。

好-这有点不合常理,但是可以。
The following URL is a working example:
需要index.html文件上一些旧式本机JavaScript的帮助。首先,我需要能够读取包含来自JSON的条目数的隐藏字段。然后将所有UL设置为不显示-setTimeout是为了确保已加载JSON文件
<script type="text/javascript">
var mTO = setTimeout(function () {
for (var x = 31; x <= $(".numRows").val() - 1; x++) {
if (typeof (document.getElementById('sp_' + x)) === 'undefined') {
} else {
document.getElementById('sp_' + x).style.display = 'none'
}
}
}, 1000);
mTO;
</script>
此后,调用计算的用户创建的方法来将this.mVar设置为元素/条目/属性的数量(无论您要使用什么名称),以便Vue知道有多少个元素,以便我们可以划分按要分页的页面数
computed: {
mFunc: function () {
this.mVar = Object.keys(this.items).length
return Object.keys(this.items).length
}
}
这是上述黑客攻击的另一部分-根据在分页部分中点击的页面,这确定了隐藏内容和显示内容
setPage: function (page) {
this.page = page
// console.log(page)
for (var y = 0; y <= this.mVar - 1; y++) {
if (typeof (document.getElementById('sp_' + y)) === 'undefined') {
} else {
document.getElementById('sp_' + y).style.display = 'none'
}
}
for (var x = (30 * (this.page - 1)); x <= 30 * (this.page); x++) {
if (typeof (document.getElementById('sp_' + x)) === 'undefined' || (document.getElementById('sp_' + x)) == null) {
break
} else {
document.getElementById('sp_' + x).style.display = 'block'
}
}
}
如果您想知道“ 30”是什么意思,那就是我希望每页显示的UL数量。
黑客的最后一部分位于模板部分
<pagination :records="mFunc" :per-page="30" @paginate="setPage"></pagination>
<span style="display: none;"><input type="hidden" class="numRows" :value="this.mVar" /></span>
如果您想使用全部内容,则可以在我的github上找到它:
