How do i make the table below to be hidden until i search content from the search bar? i want the table to not show until the table is filtered with the search bar
<html>
<div class="students">
Students
<input type="text" id="studsearch" onkeyup="StudentSearch()" placeholder="Search Student Number">
<body>
<table border ="1" cellpadding="0" id="studtable">
<tr>
<th>Student No.</th>
<th>Full Name</th>
</tr>
<tr id="stud1">
<td>1</td>
<td>John</td>
</tr>
<tr id="stud2">
<td>2</td>
<td>Mike</td>
</tr>
</table>
</body>
</div>
<script>
function StudentSearch() {
var input, filter, table, tr, td, i, txtValue;
input = document.getElementById("studsearch");
filter = input.value.toUpperCase();
table = document.getElementById("studtable");
tr = table.getElementsByTagName("tr");
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 = "";
foundHit = true;
} else {
tr[i].style.display = "none";
}
}
}
}
</script>
</html>
Im expecting the table to be hidden until searched
To hide the table initially and only show it when there is a search result, you can add a CSS style to the table element to set its initial display to "none". Then, modify your JavaScript code to show the table only when there is at least one search result.
You can try this:
<html>
<head>
<style>
#studtable {
display: none;
}
</style>
</head>
<body>
<div class="students">
Students
<input type="text" id="studsearch" onkeyup="StudentSearch()" placeholder="Search Student Number">
</div>
<table border="1" cellpadding="0" id="studtable">
<tr>
<th>Student No.</th>
<th>Full Name</th>
</tr>
<tr id="stud1">
<td>1</td>
<td>John</td>
</tr>
<tr id="stud2">
<td>2</td>
<td>Mike</td>
</tr>
</table>
<script>
function StudentSearch() {
var input, filter, table, tr, td, i, txtValue;
input = document.getElementById("studsearch");
filter = input.value.toUpperCase();
table = document.getElementById("studtable");
tr = table.getElementsByTagName("tr");
var foundHit = false;
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 = "";
foundHit = true;
} else {
tr[i].style.display = "none";
}
}
}
if (foundHit) {
table.style.display = "";
} else {
table.style.display = "none";
}
}
</script>
</body>
</html>
With this code, the table will be hidden when the page first loads. Only when there is at least one search result, the table will be shown.
Add a css style to hide the table
table {
display: none;
}
Assuming there is a filter button/ search button
<input type="text" id="filter-input">
<button id="filter-button">Filter</button>
Add an event listener to the filter button that will show the table and filter its content when clicked,
//Filtering
const filterButton = document.getElementById("filter-button");
filterButton.addEventListener("click", function() {
// Get the filter criteria from the input field
const filter = document.getElementById("filter-input").value;
// Filter the table rows based on the criteria
const tableRows = document.getElementsByTagName("tr");
for (let i = 0; i < tableRows.length; i++) {
const row = tableRows[i];
const cells = row.getElementsByTagName("td");
let shouldShowRow = false;
for (let j = 0; j < cells.length; j++) {
const cell = cells[j];
if (cell.textContent.includes(filter)) {
shouldShowRow = true;
break;
}
}
if (shouldShowRow) {
row.style.display = "";
} else {
row.style.display = "none";
}
}
// Show the table
const table = document.getElementsByTagName("table")[0];
table.style.display = "";
});
I am trying to print a 2-d array that i get from an http request to the variable value using this code
<table style="width:100%">
<tr>
<th>Name</th>
<th>Age</th>
<th>School</th>
</tr>
<script>
var x ="", i;
var y ="", j;
for (i=0; i<value.length; i++) {
x ="<tr>" +
for (j=0; j<3; j++){
y = "<td>" + {{ value[i][j] }} + "</td>";
}
+ "</tr>";
}
</script>
</table>
Any ideas why it isn't working? :P
Tag <script> not displayed in any way, you need to use JavaScript methods for DOM manipulation
const values = [
["name1", "age1", "school1"],
["name2", "age2", "school2"],
];
const tbody = document.querySelector("tbody");
for (let i = 0; i < values.length; i++) {
const tr = document.createElement("tr");
const fields = values[i];
for (let j = 0; j < fields.length; j++) {
const field = fields[j];
const td = document.createElement("td");
td.textContent = field;
tr.appendChild(td);
}
tbody.appendChild(tr);
}
<table style="width: 100%;">
<thead>
<tr>
<th>Name</th>
<th>Age</th>
<th>School</th>
</tr>
</thead>
<tbody></tbody>
</table>
You are trying to concatenate string with a for loop. You cannot do that. Also, declare i and j variables inside the for loop so they are automatically removed when the loop is done. You do not need the y variable because you can create a long string as x and then use it as innerHTML somewhere. Lastly, the value array was incorrectly used. {} is used to create an object. For example var b = {}; When you want to actually use the object, you refer to it by its name, but you said you have an array already.
<script>
var x ="";
for (var i=0; i<value.length; i++) {
x +="<tr>";
for (var j=0; j<value[i].length; j++){
x += "<td>" + value[i][j] + "</td>";
}
x += "</tr>";
}
//use your output x variable here
</script>
I have seen many ways to make the header fixed on a standard table, but usually this involves cloning the table (to match the variable widths). This of course would not work for me as the header is clickable, allowing people to sort the contents of certain rows.
So, is there a way to essentially 'freeze' the header row while still retaining the functionality of the sort?
Here is the basic table code (all css kept in 'stylesheet' for cleanliness & likewise with js)
var stIsIE = /*#cc_on!#*/false;
sorttable = {
init: function() {
// quit if this function has already been called
if (arguments.callee.done) return;
// flag this function so we don't do the same thing twice
arguments.callee.done = true;
// kill the timer
if (_timer) clearInterval(_timer);
if (!document.createElement || !document.getElementsByTagName) return;
sorttable.DATE_RE = /^(\d\d?)[\/\.-](\d\d?)[\/\.-]((\d\d)?\d\d)$/;
forEach(document.getElementsByTagName('table'), function(table) {
if (table.className.search(/\bsortable\b/) != -1) {
sorttable.makeSortable(table);
}
});
},
makeSortable: function(table) {
if (table.getElementsByTagName('thead').length == 0) {
// table doesn't have a tHead. Since it should have, create one and
// put the first table row in it.
the = document.createElement('thead');
the.appendChild(table.rows[0]);
table.insertBefore(the,table.firstChild);
}
// Safari doesn't support table.tHead, sigh
if (table.tHead == null) table.tHead = table.getElementsByTagName('thead')[0];
if (table.tHead.rows.length != 1) return; // can't cope with two header rows
// Sorttable v1 put rows with a class of "sortbottom" at the bottom (as
// "total" rows, for example). This is B&R, since what you're supposed
// to do is put them in a tfoot. So, if there are sortbottom rows,
// for backwards compatibility, move them to tfoot (creating it if needed).
sortbottomrows = [];
for (var i=0; i<table.rows.length; i++) {
if (table.rows[i].className.search(/\bsortbottom\b/) != -1) {
sortbottomrows[sortbottomrows.length] = table.rows[i];
}
}
if (sortbottomrows) {
if (table.tFoot == null) {
// table doesn't have a tfoot. Create one.
tfo = document.createElement('tfoot');
table.appendChild(tfo);
}
for (var i=0; i<sortbottomrows.length; i++) {
tfo.appendChild(sortbottomrows[i]);
}
delete sortbottomrows;
}
// work through each column and calculate its type
headrow = table.tHead.rows[0].cells;
for (var i=0; i<headrow.length; i++) {
// manually override the type with a sorttable_type attribute
if (!headrow[i].className.match(/\bsorttable_nosort\b/)) { // skip this col

// make it clickable to sort

I have a nice/working solution with jQuery.
Assume your table's class is "fixed_header" then add following code:
CSS:
.fixed_header{position:relative; border-collapse: collapse;}
JavaScript:
var originalHeader;
var floatingHeader;
$(document).ready(function () {
var tableObj=$('.fixed_header'); //or other CSS selector as `#tableId`
var tableBaseTop = tableObj.offset().top;
originalHeader = $('.fixed_header tr:first-child'); //change CSS selector here also
floatingHeader = originalHeader.clone();
floatingHeader
.css('position', 'absolute')
.css('top', 0);
setFloatingHeaderSize();
tableObj.prepend(floatingHeader);
$(window).scroll(function () {
var windowTop = $(window).scrollTop();
if (windowTop > tableBaseTop && windowTop < tableBaseTop + tableObj.height() - 100)
floatingHeader.css('top', windowTop - tableBaseTop);
else floatingHeader.css('top', 0); //floating-header is just on Original-one
});
$(window).resize(setFloatingHeaderSize);
});
function setFloatingHeaderSize() {
var originalThs = originalHeader.find('th');
var floatingThs = floatingHeader.find('th');
for (var i = 0; i < originalThs.length; i++) {
floatingThs.eq(i)
.css('width', originalThs.eq(i).width())
.css('height', originalThs.eq(i).height());
}
}
Best part of it, you don't need to change anything in you HTML, it'll directly work on any TABLE, just replace class-name(OR any other css-selector to that table) of table in which header should be fixed.
Concept: It creates a clone header(first row) and display above original one. We set the listener-function for window-scroll event AND when table-scrolled to TOP-of-Window then original one goes-up and clone one remains at top, coz we set it's margin-top to scrolled height. See at this line: if (windowTop > tableBaseTop && windowTop < tableBaseTop + tableObj.height() - 100).
Trick For Your Case: For your clickable feature on clone header, I would rather suggest you to apply your event listener on cloned-header, after cloning header(after following line): tableObj.prepend(floatingHeader);. Coz, cloned-header will be one top always, when user will click on any column-head, the event will we actually captured by cloned-header.
If your events are automatically set by any script(means not in your control), then either try putting(running) that script after above(my-js) OR apply click-event-listener on cloned-header's column for original-one, so that if anybody click then original's click event will also fire.
Code-ex:
function simulateClickOnOriginal() {
var originalThs = originalHeader.find('th');
var floatingThs = floatingHeader.find('th');
for (var i = 0; i < floatingThs.length; i++) {
floatingThs.eq(i).click(function(){
originalThs.eq(i).trigger( "click" );
});
}
}
Hi there,
I created an HTML table and what I need is to find the column index of a particular value,
but I don't know how to access each value of a table. That is why I am unable to get the index of the column.
Here is my table.
<table>
<tr>
<td>01</td>
<td>02</td>
<td>03</td>
</tr>
<tr>
<td>04</td>
<td>05</td>
<td>06</td>
</tr>
<tr>
<td>07</td>
<td>08</td>
<td>09</td>
</tr>
</table>
and I want the index of the value 03.
The following is a working code, first traverse the table to get the values in this, then compare with your required value and find the index of it..,
<html>
<head>
<script>
function cellvalues() {
var table = document.getElementById('mytable');
for (var r = 0, n = table.rows.length; r < n; r++) {
for (var c = 0, m = table.rows[r].cells.length; c < m; c++) {
var hi=table.rows[r].cells[c].innerHTML;
if(hi==03)
{
alert(table.rows[r].cells[c].cellIndex);
}
}
}
}
</script>
</head>
<body>
<table id="mytable">
<tr><td>01</td><td>02</td><td>03</td>
</tr>
<tr><td>04</td><td>05</td><td>06</td>
</tr>
<tr><td>07</td><td>08</td><td>09</td>
</tr>
</table>
<input type="button" onclick=cellvalues()>
</body>
</html>
You can try this (untested)
var tab = document.getElementsByTagName("table")[0];
var tr = tab.childNodes;
for (var i = 0; i < tr.length; i++) {
var td = tr[i].childNodes;
for (var j = 0; j < tr.length; j++) {
if (td[j].innerHTML == "03") {
alert(i + "," + j);
}
}
}
I suggest using jQuery index for this:
var trCollection = $('table tr');
$('table td').each(function () {
console.log(trCollection.index($(this).parent()));
});
I need my HTML table to be editable so that user inserted data could be sent to the server. However due to the table's size (50 rows) it would not be convenient for users to insert data points one-by one if I introduce contenteditable attribute as following:
<table>
<tr><td><div contenteditable>editable</div></td><td><div contenteditable>editable</div></td></tr>
//...........
</table>
How can I make my table be editable similar to excel spreadsheet, if possible without using dojo etc?
I have done this in Java using ExcelAdapter class. Is there any way I could do it in HTML?
You can add a listener to the input event of each cell, and if the cell contains multiple data items split them across the next cells.
function init()
{
var tables = document.getElementsByClassName("editabletable");
var i;
for (i = 0; i < tables.length; i++)
{
makeTableEditable(tables[i]);
}
}
function makeTableEditable(table)
{
var rows = table.rows;
var r;
for (r = 0; r < rows.length; r++)
{
var cols = rows[r].cells;
var c;
for (c = 0; c < cols.length; c++)
{
var cell = cols[c];
var listener = makeEditListener(table, r, c);
cell.addEventListener("input", listener, false);
}
}
}
function makeEditListener(table, row, col)
{
return function(event)
{
var cell = getCellElement(table, row, col);
var text = cell.innerHTML.replace(/<br>$/, '');
var items = split(text);
if (items.length === 1)
{
// Text is a single element, so do nothing.
// Without this each keypress resets the focus.
return;
}
var i;
var r = row;
var c = col;
for (i = 0; i < items.length && r < table.rows.length; i++)
{
cell = getCellElement(table, r, c);
cell.innerHTML = items[i]; // doesn't escape HTML
c++;
if (c === table.rows[r].cells.length)
{
r++;
c = 0;
}
}
cell.focus();
};
}
function getCellElement(table, row, col)
{
// assume each cell contains a div with the text
return table.rows[row].cells[col].firstChild;
}
function split(str)
{
// use comma and whitespace as delimiters
return str.split(/,|\s|<br>/);
}
window.onload = init;
Demo: http://jsfiddle.net/yRnkF/
you can achieve this easily by adding handsontable
change any div to a excel table
var $container = $("#divid");
$container.handsontable({
data: getData(),
rowHeaders: true,
colHeaders: true,
contextMenu: true //forces dom to use custom right click functionality like add row delete row add column etc
});

Pure javascript. Just mark a table with 'editabletable' class.
index.html:
<table class="editabletable" border="1">
<tr> <td>a</td> <td>b</td> <td>c</td> </tr>
<tr> <td>d</td> <td>e</td> <td>f</td> </tr>
<tr> <td>g</td> <td>h</td> <td>i</td> </tr>
</table>
<script src="index.js"></script>
index.js:
function makeeditable(table) {
for (let i = 0; i < table.rows.length; i++) {
for (let j = 0; j < table.rows[i].cells.length; j++) {
// with contenteditable in each cell, it is possible to navigate through them with tab key
table.rows[i].cells[j].setAttribute("contenteditable", "true");
}
}
}
function addpastelistener(table) {
table.addEventListener('paste', (event) => {
event.preventDefault();
let paste = (event.clipboardData || window.clipboardData).getData('text');
let col = event.target;
while (col && col.tagName != 'TD') col = col.parentElement;
let row = col;
while (row && row.tagName != 'TR') row = row.parentElement;
let tab = row;
while (tab && tab.tagName != 'TBODY' && tab.tagName != 'TABLE') tab = tab.parentElement;
let rows = paste.replace(/(\r\n)|\r|\n/g, '\n').split("\n");
for (let i = 0, r = row.rowIndex; i < rows.length && r < table.rows.length; i++) {
let cells = rows[i].split("\t");
for (let j = 0, c = col.cellIndex; j < cells.length && c < table.rows[r].cells.length; j++) {
table.rows[r].cells[c].innerHTML = cells[j].trim();
c++;
}
r++;
}
});
}
function init() {
const editabletables = document.getElementsByClassName('editabletable');
for (let i = 0; i < editabletables.length; i++) {
makeeditable(editabletables[i]);
addpastelistener(editabletables[i]);
}
}
init();
