- 我正在尝试执行此操作，而是在同一个表的多个列中进行搜索:[https://www.w3schools.com/howto/howto_js_filter_table.asp][1]
- 在上面的示例中，我不仅希望按“名称”进行过滤，还希望按“国家/地区”进行过滤。
- 我在这里找到了类似的帖子，但它是针对七个单独的列，并且我找不到其他普通的 JS 代码:[https://stackoverflow.com/questions/47274028/filtering-table-with-multiple-filters ?answertab=oldest#tab-top][2]
- 我尝试复制循环(如下所示)，但显然这不起作用，因为匹配与第一个循环冲突。
这对我来说有点太先进了，我需要一个解决方案。如有任何帮助，我们将不胜感激。
function myFunction() {
// Declare variables
var input, filter, table, tr, td, i, txtValue;
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++) {
td1 = tr[i].getElementsByTagName("td")[0];
if (td1) {
txtValue1 = td1.textContent || td1.innerText;
if (txtValue1.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
// this is what i've tried adding, but oviously, it conflicts with the first loop when matching
for (j = 0; j < tr.length; j++) {
td2 = tr[j].getElementsByTagName("td")[1];
if (td2) {
txtValue2 = td2.textContent || td2.innerText;
if (txtValue2.toUpperCase().indexOf(filter) > -1) {
tr[j].style.display = "";
} else {
tr[j].style.display = "none";
}
}
}
}
最佳答案
也许这个修改后的功能对你有帮助。基本的变化是它不在单个表格单元格内搜索，而是在完整表格行的串联文本内容内搜索。
function myFunction() {
var input, filter, table, tr, td, i, txtValue;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
for (i = 0; i < tr.length; i++) {
var rowContent = tr[i].textContent;
rowContent = rowContent.replace(/[\s]+/g, ' ');
//console.log(rowContent);
if (rowContent) {
if (rowContent.toUpperCase().includes(filter)) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
