I have a table with many rows, each row has each own id. I want when i hover the row, i can get it's ID (i will process php to get the data), and append to the div (div will fade out after hover).
<table id="listtemp" class="table datatable">
<thead>
<tr>
<th>Số PO</th>
<th>Số hợp đồng</th>
<th>Số hóa đơn</th>
<th>Doanh nghiệp</th>
<th>Người mua</th>
<th>Sales</th>
<th>Ngày tạo</th>
<th>Tình trạng</th>
<th>Chi tiết</th>
</tr>
</thead>
<tbody>
<?php
for($i = 0; $i < 10; $i++){
?>
<tr id="<?=$i;?>">
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<?php } ?>
</tbody>
</table>
Using JQuery bind table tr hover and just get id from that.
$('#waypointsTable tr').hover(function() {
console.log($(this).attr('id'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<table id="waypointsTable" border="1">
<tbody>
<tr id="1">
<td>some text</td>
</tr>
<tr id="2">
<td>some text</td>
</tr>
<tr id="3">
<td>some text</td>
</tr>
</tbody>
</table>
Here you go with an example of getting Id on hover https://jsfiddle.net/r6tbv9uz/
$('table tbody tr').hover(function(){
console.log($(this).attr('id'))
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tbody>
<tr id="1">
<td>test</td>
</tr>
<tr id="2">
<td>test</td>
</tr>
<tr id="3">
<td>test</td>
</tr>
<tr id="4">
<td>test</td>
</tr>
</tbody>
</table>
best way is to write a hover function
$('#table tr').on('hover',function(){
var id = $(this).attr('id');
})
It will be better if you use mouseenter event rather than hover because hover event will be triggered when you will take your pointer on the row and when you will leave it.
So it will initiate your php request two times when you enter your pointer on a row and when you leave. And so, probably it will leave the info DIV there on the row and it will not fadeout.
Instead use mouseenter like this:
$('table tbody tr').on('mouseenter',function(){
var id = $(this).attr('id');
});
In the beiginning add class hidden to tbody.
<script>
$("#listtemp tr").hover(function (){
id = $(this).attr('id');
$.ajax({
type: 'POST',
dataType: 'json',
url: 'name of php file to get data',
data: { id: id }, //sending id to php file
success: function(response) {
$('tbody').removeClass('hidden');
$('tbody').fadeOut();
}
});
});
})
</script>

I have create a table with following style. Now I want to get first td value as 1,2,3 using jQuery.
<html>
<head>
<style type='text/css'>
table {
counter-reset: rowNumber;
}
table tr {
counter-increment: rowNumber;
}
table tr td:first-child::before {
content: counter(rowNumber);
min-width: 1em;
margin-right: 0.5em;
}
</style>
</head>
<body>
<table border="1" id="MyTable">
<tr>
<td></td> <td>blue</td>
</tr>
<tr>
<td></td><td>red</td>
</tr>
<tr>
<td></td><td>black</td>
</tr>
</table>
</body>
</html>
I tried with following script but it showing row counter as text. How to get the value of first td?
<script>
$("#MyTable").find('tr').each(function (i, el) {
$(this).find('td:eq(0)').each(function () {
console.log(window.getComputedStyle(this, ':before').content);
});
});
</script>
Based on this:
Generated content does not alter the document tree. In particular, it is not fed back to the document language processor.
So if you see the html that generated, you will see all td is empty while you see counter (1,2,3) in page. this is html generated:
But this is result:
So generated content does not alter the document tree and you can't access to value of it.
There are lots of alternative you can do it:
$("#MyTable").find('tr').each(function (i, el) {
debugger
$(this).find('td:eq(0)').each(function (index, el) {
$(this).html(i+1)
console.log($(this).html());
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table border="1" id="MyTable">
<tbody>
<tr>
<td></td>
<td>blue</td>
</tr>
<tr>
<td></td>
<td>red</td>
</tr>
<tr>
<td></td>
<td>black</td>
</tr>
</tbody>
</table>
Update
You can rest number after each modification on your table:
function setnumber() {
$('#MyTable tbody tr').each(function (i) {
$($(this).find('td')[0]).html(i + 1);
});
}
$(".delete").click(function () {
$(this).closest('tr').remove();
setnumber();
});
setnumber();
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table border="1" id="MyTable">
<tbody>
<tr>
<td></td>
<td>blue</td>
<td><span class="delete"><i class="fas fa-trash"></i>delete</span></td>
</tr>
<tr>
<td></td>
<td>red</td>
<td><span class="delete"><i class="fas fa-trash"></i>delete</span></td>
</tr>
<tr>
<td></td>
<td>black</td>
<td><span class="delete"><i class="fas fa-trash"></i>delete</span></td>
</tr>
</tbody>
</table>
Probably, you want to put 1,2,3 in TDS on DOM.
You can do like this:
$("#MyTable").find('tr').each(function (i, el) { $(el).find("td").eq(0).text(i); });
https://codesandbox.io/s/jquery-playground-forked-pmtgc?file=/src/index.js
You can use child selector to select the child of tr
jQuery("body > table > tr:nth-child(1) > td:nth-child(1)").text();
i have two tables
<table id='standings'>
<tr id='tableTeam1'>
<td>Team1</td>
</tr>
<tr id='tableTeam2'>
<td>Team2</td>
</tr>
<tr id='tableTeam3'>
<td>Team3</td>
</tr>
</table>
<table id='matches'>
<tr id='match1'>
<td id='matchTeam1>Team1</TD>
<td class='score'> 22-31</td>
<td id='matchTeam3>Team3</td>
</tr>
</table>
My goal is to hover over the row with id 'match1' from the second table and have the rows with id 'tableTeam1' and 'tableTeam3' highlighted
1.)
how is this possible by js/css?
2.) How can it be done by using a php database request when
"Select tableTeam1,tableTeam2 from matches where id='match1'"
Thank you so much in advance
Try this:
$('#match1')
.mouseenter(function() {
$('#tableTeam1').addClass('highlighted');
})
.mouseleave(function() {
$('#tableTeam1').removeClass('highlighted');
})
You also need to add some CSS there, like this one:
.highlighted { background-color: red;}
I don't know your data structure but it should be something like that, I think:
...
<tr id="<?php echo $data['column_name']; ?>" <?php echo ($data['column_name'] === 'match1')? 'class="highlighted"' : ''; ?>>
...
Put your team numbers in a data attribute in rows of the matches then it is fairly simple to parse them to match the elements in the other table and toggle a class on them
$('#matches .match-row').hover(function() {
const teams = $(this).data('teams');
teams.forEach(num => $('#tableTeam' + num).toggleClass('active'))
})
tr.active {
color: red
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id='standings' border=1>
<tr id='tableTeam1'>
<td>Team1</td>
</tr>
<tr id='tableTeam2'>
<td>Team2</td>
</tr>
<tr id='tableTeam3'>
<td>Team3</td>
</tr>
</table>
<table id='matches' border=1>
<tr class="match-row" data-teams="[1,3]">
<td>Team1</td>
<td class='score'> 22-31</td>
<td>Team3</td>
</tr>
<tr class="match-row" data-teams="[2,3]">
<td>Team2</td>
<td class='score'> 55-1 Blowout!</td>
<td>Team3</td>
</tr>

I have the following table
<table width="97%" border="1" class="queueList">
<thead>
<tr>
<th>Delete</th>
<th>Queue Name</th>
<th>Current queue length</th>
</tr>
</thead>
<tbody>
#foreach (var item in Model.ImportQueues)
{
<tr id="watchRow">
<td id="DeleteButton">X</td>
<td id="QueueName", value="#item.QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
}
</tbody>
how can I get the value of the element "QueueName" when "#DeleteRow" is clicked, using JQuery ?
So far I have
$("body").on("click", "#DeleteButton", function (event) {
var queueName = $(event.target).closest("div.queueList").find("#QueueName");
alert(queueName);
}
Use the data attribute to store the desired value on the button itself
<tr class="watchRow">
<td class="DeleteButton" data-queuename="#item.QueueName">X</td>
<td class="QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
then on click of TD (by the way, it should be a button)
$("body").on("click", ".DeleteButton", function() {
var queueName = $(this).data("queuename");
alert(queueName);
}
If you want to use this name on other buttuns also, like edit etc. then it is better to assign it to the whole row:
<tr class="watchRow" data-queuename="#item.QueueName">
<td class="DeleteButton">X</td>
<td class="QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
and read it like this:
$("body").on("click", ".DeleteButton", function() {
var queueName = $(this).closest('tr').data("queuename");
alert(queueName);
}
Without JQuery
<tr id="watchRow">
<td class="DeleteButton" onclick="deleteItem(#item.QueueName)">X</td>
<td value="#item.QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
<script>
function deleteItem(item) {
alert(item)
}
</script>
With JQuery
<tr id="watchRow">
<td class="DeleteButton">X</td>
<td value="#item.QueueName">#item.QueueName</td>
<td>#item.CurrentQueueLength</td>
</tr>
<script>
$(".DeleteButton").on("click", function() {
alert($(this).next("td").html());
}
</script>
</script>
I started on that http://jsfiddle.net/DRFBG/
And if I add tables so mytable1, mytable2,...
<table id="mytable1" border="1">
<tr><th>Column1</th><th>Column2</th><th>Column3</th><th>Column4</th></tr>
<tr class="data"><td>1st</td><td>1.1</td><td></td><td>1</td></tr>
<tr class="data"><td>2nd</td><td>2.01</td><td></td><td>2</td></tr>
<tr class="data"><td>3rd</td><td>3.001</td><td></td><td>3</td></tr>
<tr class="data"><td>4th</td><td>4.01</td><td></td><td>4</td></tr>
</table>
<table id="mytable2" border="1">
<tr><th>Column1</th><th>Column2</th><th>Column3</th><th>Column4</th></tr>
<tr class="data"><td>1st</td><td>1.1</td><td>1</td><td></td></tr>
<tr class="data"><td>2nd</td><td>2.01</td><td>2</td><td></td></tr>
<tr class="data"><td>3rd</td><td>3.001</td><td>3</td><td></td></tr>
<tr class="data"><td>4th</td><td>4.01</td><td>4</td><td></td></tr>
</table>
How could I uniform my javascript code for all tables?
I've already tried passing by table[div^=mytable]*, but the problem is the second selector in the function.
So any ideas please? Thank you? Sorry for my english
By the way, the code is to remove th with empty td for each table
$('#mytable2 th').each(function(i) {
var remove = 0;
var tds = $(this).parents('table').find('tr td:nth-child(' + (i + 1) + ')')
tds.each(function(j) { if (this.innerHTML == '') remove++; });
if (remove == ($('#mytable2 tr').length - 1)) {
$(this).hide();
tds.hide();
}
});
One approach is, selecting tables first and get their id and after that, doing the approach of http://jsfiddle.net/DRFBG/ on each of them like the following:
$('table').each(function()
{
var tb_id = $(this).attr('id');
$('#'+tb_id+' th').each(function(i) {
var remove = 0;
var tds = $(this).parents('table').find('tr td:nth-child(' + (i + 1) + ')')
tds.each(function(j) { if (this.innerHTML == '') remove++; });
if (remove == ($('#'+tb_id+' tr').length - 1)) {
$(this).hide();
tds.hide();
}
});
});
Here is the working jsfiddle
To select all on your page you can use "table" selector.
So you'd need to use $('table2 th') instead of $('#mytable2 th')
One possible solution would be to loop through each column of each table, then check if there are any non-empty cells. If there is not, then you can safely remove() all the td and th within that column.
Note that the removal needs to be done last, otherwise it will affect the indexing of the following columns. You can do that by simply marking the cells to be removed with a class, and then selecting that class once all loops complete. Try this:
$('table').each(function() {
var $table = $(this);
var rows = $table.find('tr').length - 1; // -1 to account for the headings
$table.find('th').each(function(i, th) {
var $empty = $table.find(`td:nth-child(${i + 1}):empty`);
if ($empty.length == rows)
$empty.add(this).addClass('to-remove');
})
$table.find('.to-remove').remove();
});

How can I get first value/column of row on clicking row.
I found following example doing the same.
http://www.vbforums.com/showthread.php?522104-HTML-table-on-click-event
But I don't want to add event to each row manually as my table is having billions of records. Please help me. How can I get the row value (first column) on clicking row?
$("#toppings tr").click(function(){
alert( $(this).children().closest("td").html());
});
fiddle:
http://jsfiddle.net/k1ezbcrk/
example for one row could be
<tr id="id2">
<td>12</td>
<td>row22</td>
<td>row23</td>
</tr>
<script>
function getColumnValue(elem){
alert(elem.innerHTML);
}
</script>
$("#toppings tr").click(function(){
alert( $(this).children().first().html());
});
You could use event delegation
var table = document.getElementsByTagName('table')[0];
function getValue(){
console.log(event.target.parentElement.firstElementChild.innerText);
}
table.addEventListener('click', getValue, false);
