我想弄清楚如何使所有 5 列和行都可搜索。目前它仅通过第一列 (DATE
) 进行搜索。有人可以帮我搜索所有的列和行吗?我包含了 HTML、CSS 和 javascript 以尝试提供尽可能多的信息。
function myFunction() {
// Declare variables
var input, filter, table, tr, td, i;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
// Loop through all table rows, and hide those who don't match the search query
for (i = 0; i < tr.length; i++) {
td = tr[i].getElementsByTagName("td")[0];
if (td) {
if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
}
#myInput {
background-image: url('/css/searchicon.png'); /* Add a search icon to input */
background-position: 10px 12px; /* Position the search icon */
background-repeat: no-repeat; /* Do not repeat the icon image */
width: 100%; /* Full-width */
font-size: 16px; /* Increase font-size */
padding: 12px 20px 12px 40px; /* Add some padding */
border: 1px solid #ddd; /* Add a grey border */
margin-bottom: 12px; /* Add some space below the input */
}
#myTable {
border-collapse: collapse; /* Collapse borders */
width: 100%; /* Full-width */
border: 1px solid #ddd; /* Add a grey border */
font-size: 18px; /* Increase font-size */
}
#myTable th, #myTable td {
text-align: left; /* Left-align text */
padding: 12px; /* Add padding */
}
#myTable tr {
/* Add a bottom border to all table rows */
border-bottom: 1px solid #ddd;
}
#myTable tr.header, #myTable tr:hover {
/* Add a grey background color to the table header and on hover */
background-color: #f1f1f1;
}
<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search for names..">
<table id="myTable">
<tr class="header">
<th style="width:20%;">Date</th>
<th style="width:20%;">Home</th>

最佳答案
使用现有代码,像循环表格行一样循环表格单元格。
在下面,我隐藏了每一行。对于每一行,如果单元格中的文本与搜索词匹配,则显示该行并且循环 continues到下一行。
我还使用 tBodies
忽略了表格标题将搜索限制为 <tr>
第一个 <tbody>
内的元素.或者,您可以检查 <td>
搜索前行中存在元素;类似于:if (tds.length) > 0
.
function performSearch() {
// Declare search string
var filter = searchBox.value.toUpperCase();
// Loop through first tbody's rows
for (var rowI = 0; rowI < trs.length; rowI++) {
// define the row's cells
var tds = trs[rowI].getElementsByTagName("td");
// hide the row
trs[rowI].style.display = "none";
// loop through row cells
for (var cellI = 0; cellI < tds.length; cellI++) {
// if there's a match
if (tds[cellI].innerHTML.toUpperCase().indexOf(filter) > -1) {
// show the row
trs[rowI].style.display = "";
// skip to the next row
continue;
}
}
}
}
// declare elements
const searchBox = document.getElementById('searchBox');
const table = document.getElementById("myTable");
const trs = table.tBodies[0].getElementsByTagName("tr");
// add event listener to search box
searchBox.addEventListener('keyup', performSearch);
#searchBox {
box-sizing: border-box;
width: 100%;
font-size: 16px;
padding: 12px 20px 12px 40px;
border: 1px solid #ddd;
margin-bottom: 12px;
}
#myTable {
border-collapse: collapse;
width: 100%;
border: 1px solid #ddd;
font-size: 18px;
}
#myTable th,
#myTable td {
text-align: left;
padding: 12px;
}
#myTable th {
width: 20%;
}
#myTable tr {
border-bottom: 1px solid #ddd;
}
#myTable tr.header,
#myTable tr:hover {
background-color: #f1f1f1;
}
<input type="text" id="searchBox" placeholder="Search for names..">
<table id="myTable">
