我正在尝试通过在搜索表单中编写一些文本来过滤此HTML表格,这种方法效果很好,但是每当进行过滤时,元素都会尝试填充表格的整个宽度,而不是保持其原始元素宽度(25%表的宽度,而不计算单元格之间的间隔。
function searchFilter () {
const input = document.getElementById('myInput');
const filter = input.value.toUpperCase();
const table = document.getElementById('tablaPiola');
const articule = table.getElementsByTagName('td');
for (i = 0; i < articule.length; i++) {
a = articule[i].getElementsByTagName("a")[0];
txtValue = a.textContent || a.innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
articule[i].style.display = "";
} else {
articule[i].style.display = "none";
}
}
}
document.getElementById("filter-btn").addEventListener("click", searchFilter);
body {
background-color: black;
}
table
{border-spacing: 20px;
table-layout: fixed;
width: 600px;
margin: auto;
margin-top: 10px;}
td
{text-align: center;
border-radius: 10px;}
td a
{width: 100%;
display: block;
line-height: 50px;
text-decoration: none;
font-family: "Poppins";
font-weight: 700;
font-size: 12px;
color: white;}

答案 0 :(得分:2)
我原本以为visibility: hidden
,但您指出那意味着所显示的内容不再位于左侧。
我唯一的其他想法是在最后添加填充单元:
function searchFilter () {
const input = document.getElementById('myInput');
const filter = input.value.toUpperCase();
const table = document.getElementById('tablaPiola');
// Remove any fillers we added last time
table.querySelectorAll(".filler").forEach(filler => {
filler.parentNode.removeChild(filler);
});
const articule = table.getElementsByTagName('td');
// Remember how many are showing at the end
let showing = 0;
for (i = 0; i < articule.length; i++) {
a = articule[i].getElementsByTagName("a")[0];
txtValue = a.textContent || a.innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
articule[i].style.display = "";
++showing; // Remember we're showing this one
} else {
articule[i].style.display = "none";
}
}
// Grab the length (since `articule` is a live list
const max = articule.length;
// Add blank cells to the end
while (showing < max) {
const filler = document.createElement("td");
filler.className = "filler";
table.appendChild(filler);
++showing;
}
}
实时示例:
function searchFilter () {
const input = document.getElementById('myInput');
const filter = input.value.toUpperCase();
const table = document.getElementById('tablaPiola');
// Remove any fillers we added last time
table.querySelectorAll(".filler").forEach(filler => {
filler.parentNode.removeChild(filler);
});
const articule = table.getElementsByTagName('td');
// Remember how many are showing at the end
let showing = 0;
for (i = 0; i < articule.length; i++) {
a = articule[i].getElementsByTagName("a")[0];
txtValue = a.textContent || a.innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
articule[i].style.display = "";
++showing; // Remember we're showing this one
} else {
articule[i].style.display = "none";
}
}
// Grab the length (since `articule` is a live list
const max = articule.length;
// Add blank cells to the end
while (showing < max) {
const filler = document.createElement("td");
filler.className = "filler";
table.appendChild(filler);
++showing;
}
}
document.getElementById("filter-btn").addEventListener("click", searchFilter);

其他一些与主要问题没有直接关系的笔记
该代码属于我所谓的The Horror of Implicit Globals。您永远不会声明i
,a
或txtValue
,因此最终在分配给全局变量时会创建它们。我建议在所有代码中使用strict mode,以便在尝试执行此操作时出现错误。
FWIW,我看到您正在使用ES2015 +功能(例如const
),因此您可以使用for-of
循环而不是for
循环。 for-of
少打字。但是您可能需要在某些平台上进行polyfill迭代。我的答案here显示了如何做到这一点。
