我使用window.location.href作为元素过滤器。但是，当我单击筛选按钮时，并非所有元素都显示出来。我操作的那些不显示，但我直接从DB返回的是。
首先，按钮是这样的，每个月一个:
<div class="monthsButton">
<button type="button" data-month="0" >2021</button>
<button type="button" data-month="1" >Janeiro</button>
<button type="button" data-month="2" >Fevereiro</button>
const month = req.query.month;
if(month > 0) {
launch = lancamentos.filter(item => {
const data = new Date(item.data);
return (data.getMonth() + 1) == month
})
}
最后，要执行操作，按钮配置如下:
const monthsButton = document.querySelectorAll('.monthsButton button')
for (let button of monthsButton) {
const month = button.dataset.month
button.onclick = () => {
window.location.href= `?month=${month}`
}
}
问题是过滤器按钮识别日期，使用它，但它不显示过滤时，日期和数字值。
Run on you local, because use window.location ...
