I'm trying to filter a table using a JavaScript function, but I'm not sure what the issue is...When clicking the filter link, nothing happens, but it should be filtering the second column ("Platform" column) and only displaying rows with "TEST" in it.
I'm trying to debug it here:
https://jsfiddle.net/7vh5wmsx/
function filterTable(input) {
var filter = input.value.toUpperCase();
var table = document.getElementById("myTable");
var tr = table.getElementsByTagName("tr");
var tds = tr.getElementsByTagName('td');
for (var i = 0; i < tr.length; i++) {
if (tds[1].textContent.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
Use this code
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++) {
td = tr[i].getElementsByTagName("td")[0];
if (td) {
txtValue = td.textContent || td.innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
}

I want to match the value of user input with an array object and then return the same result to the table
Here is my code
function myFunction() {
var input, filter, table, tr, td, i, txtValue;
var myList = dataDummy;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
console.log(filter);
table = document.getElementById("our-table");
tr = table.getElementsByTagName("tr");
for (i = 0; i < myList.length; i++) {
td = (myList[i].nama);
console.log(myList[i].nama);
// td = tr[i].getElementsByTagName("td")[3];
if (td) {
txtValue = td.textContent || td.innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
}
here is the display when i search on the HTML
can someone tell me where did i do wrong here, the table supposed to show the same name with the input only, but it didn't works
I want to filter the numerical values of a HTML column using a direct comparison of numbers from user-input values.
This shows no output.
function myFunction2() {
var input, filter, table, tr, td, i, txtValue;
input = document.getElementById('myInput2').value
var pctstr="0"
filter = input.value.toUpperCase();
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
for (i = 0; i <= tr.length; i++) {
td = tr[i].getElementsByTagName("td")[4];
if (td) {
txtValue = td.textContent || td.innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
}
I wanted to use the same javascript filter on the same page but with two or three different tables and different input field. Here below is the script I've been using to filter out dates on a table.
What if there are 2 or more tables?
function filterFunction() {
var input, filter, table, tr, td, i, totalViewable = 0;
input = document.getElementById("event_date_range");
filter = input.value.toUpperCase();
table = document.getElementById("dateTable");
tr = table.getElementsByTagName("tr");
for (i = 0; i < tr.length; i++) {
td = tr[i].getElementsByTagName("td")[1];
tds = tr[i].getElementsByTagName("td")[0];
if (td) {
if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
totalViewable += parseFloat(tds.innerHTML);
document.getElementById("total_amount_td").innerHTML = "$" + totalViewable.toFixed(2);
} else {
tr[i].style.display = "none";
}
}
}
}
Table - dataTable
Input field - event_date_range
Output text - total_amount_td
Pass the table, input and total_amount_id as parameters to your filterFunction:
Something like:
function filterFunction(table, input, total_amount_id) {
var filter, tr, td, i, totalViewable = 0;
filter = input.value.toUpperCase();
tr = table.getElementsByTagName("tr");
for (i = 0; i < tr.length; i++) {
td = tr[i].getElementsByTagName("td")[1];
tds = tr[i].getElementsByTagName("td")[0];
if (td) {
if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
totalViewable += parseFloat(tds.innerHTML);
document.getElementById(total_amount_id).innerHTML = "$" + totalViewable.toFixed(2);
} else {
tr[i].style.display = "none";
}
}
}
}
And then call the function with different parameters:
var table1 = document.getElementById("dateTable");
var input1 = document.getElementById("event_date_range");
var total_amount_id1 = "total_amount_td";
filterFunction(table1, input1, total_amount_id1);
var table2 = document.getElementById("dateTable2");
var input2 = document.getElementById("event_date_range2");
var total_amount_id2 = "total_amount_td2";
filterFunction(table2, input2, total_amount_id2);
The below code search for the first column of any table on webpage, and i want to search the data from second column. what editing do i need to do to get the desired output ?
<script>
function myFunction() {
var input, filter, table, tr, td, i;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
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";
}
}
}
}
</script>
<script>
function myFunction() {
var input, filter, table, tr, td, i;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
for (i = 0; i < tr.length; i++) {
td = tr[i].getElementsByTagName("td")[1];
if (td) {
if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
}
</script>
Just use index '1' of td array to get second column.
td 0 for first column , td 1 for second column
just change this line from :
td = tr[i].getElementsByTagName("td")[0];
to
td = tr[i].getElementsByTagName("td")[1];
function myFunction() {
var input, filter, table, tr, td, i;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
for (i = 0; i < tr.length; i++) {
td = tr[i].getElementsByTagName("td")[1];
if (td) {
if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
}
<input id="myInput" type="text" onkeyup="myFunction()"/>
<table id="myTable" border="1">
<tr><td>1</td><td>John</td></tr>
<tr><td>2</td><td>Jonny</td></tr>
<tr><td>3</td><td>Ram</td></tr>
<tr><td>4</td><td>Shyam</td></tr>
</table>
First of all, I'm not an expert in JavaScript, so the answer will probably be simple, but currently I'm using this (https://www.w3schools.com/howto/howto_js_filter_table.asp) tutorial to filter through a table, but you can only search in 1 column, so in this example only for Name or Country, but I want to search in both columns at the same time.
What do I need to change in this code?
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";
}
}
}
}
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]; // This code only get the frist "TD" element
tds = tr[i].getElementsByTagName("td");
for (j = 0; j < td.length; j++) {
td = tds[j];
if (td) {
if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
}
}
}
You can convert the HTMLCollection returned by getElementsByTagName to an Array (check this answer for ways to do it) and then use the some method to check if 'some' of the tdvalues match your filter. If there is a match, display them. Else hide them. Here's the code:
function myFunction() {
const input = document.getElementById('myInput')
const filter = input.value.toLowerCase()
const table = document.getElementById('myTable')
const tr = [...table.getElementsByTagName('tr')]
tr.forEach((t) => {
const foundMatch = [...t.getElementsByTagName('td')].some((td) => {
return td.innerHTML.toLowerCase().indexOf(filter) > -1
})
if (foundMatch) {
t.style.display = ''
} else {
t.style.display = 'none'
}
})
}
