I have a table with several <tr>s and each one has several <td>s. The content of these columns can be another html element (for example a textbox) or just text.
My question: how I can get the rest of the siblings of one clicked element inside this column? I mean, how I can know to which <tr> this element belongs, to <tr> #3 or <tr> #5?I don't have a index per <tr> to control
Example:
If I click the textbox of column #1 in row #5, I want that the content of column #2 in row #5 change. I don't know how to do it because my <tr> doesn't have an index.
Using jQuery, add this to the event handler. This will provide you with a collection of table cells:
var columns = $(this).closest('tr').children();
// .eq() is 0-based, so this would retrieve the fourth column
columns.eq(3);
You can find the index of a row using the index() function.
$('input').click(function(){
var index = $(this).parents('tr').index();
alert('you click an input on row #' + index);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr>
<td><input type="text"></td>
<td></td>
</tr>
<tr>
<td><input type="text"></td>
<td></td>
</tr>
<tr>
<td><input type="text"></td>
<td></td>
</tr>
</table>
Use closest to get the parent TR element.
$('your_element').click(function(){
var tr = $(this).closest('tr');
var element1 = $(tr).find('element_to_find');
});
You can also use the :eq operator to find the td.
$('your_element').click(function() {
var tr = $(this).closest('tr');
var col3 = $("td:eq(2)", tr);
}

I have written a function for Add/Remove rows in a table, but the problem is that after adding a row, the CSS property of the table is not coming through properly. As in my input field is not coming in the center of the cell.
In the first row, it's displaying in the center of the cell (as it's hard-coded), but when I create a row using my function, the input field is displaying on the left side of the cell.
My code is:
function deleteRow(row) {
var i = row.parentNode.parentNode.rowIndex;
document.getElementById('POITable').deleteRow(i);
}
function insRow() {
//$('#myModal').modal('toggle');
var x = document.getElementById('POITable');
var new_row = x.rows[1].cloneNode(true);
var len = x.rows.length;
// new_row.cells[0].innerHTML = len;
var inp1 = new_row.cells[1].getElementsByTagName('input')[0];
inp1.id += len;
inp1.value = '';
x.appendChild(new_row);
}
<table id="POITable" data-toggle="table">
<tr>
<th>colmn1</th>
<th>colmn1</th>
</tr>
<tbody>
<td><input type="text"></td>
<td><input type="text"></td>
<td><a onclick="insRow()" id="addmorePOI">Add row</a></td>
<td><a onclick="deleteRow(this);" id="addmorePOI">Remove row</a></td>
</tbody>
</table>
Please take a look at the image of how it's displaying in my dashboard. Note that I am using a Bootstrap table.
Give each table data tag a similar class name and add the property in css of that class:
text-align: center;
You are missing TR tags in your table body. Should be:
<tbody>
<tr>
<td><input type="text"></td>
<td><input type="text"></td>
<td><a onclick="insRow()" id="addmorePOI">Add row</a></td>
<td><a onclick="deleteRow(this);" id="addmorePOI">Remove row</a>
</td>
</tr>
</tbody>
It looks like you have some padding coming from somehwere. You need to inspect the dom on the newly added element. I noticed that your other cells have 0 padding. try adding cellpadding="0" to the table tag or on each td add class="no-padding" (be sure to create a class for that!) and make sure that class gets added to each new td in a row that you add
I want to select a value of my table by row and column position as below description.
This tables was used by appendTo method to .tbody selector and then I've got more rows as below I just show two of rows and each of rows I have .Open selector was used for user click to get a value on column number 4 by current position or index of that row.
Here HTML:
<table class"mytable">
<tbody class="tbody">
<tr>
<td>1</td>
<td>THB-PP-000001</td>
<td>1005-000001</td>
<td>100</td> //this is the column id I want to get it
<td><button type="button" class="open"> Open by Id </button></td>
</tr>
<tr>
<td>1</td>
<td>THB-PP-000001</td>
<td>1005-000001</td>
<td>101</td> //this is the column id I want to get it
<td><button type="button" class="open"> Open by Id </button></td>
</tr>
</tbody>
</table>
This is JS:
$(document).on("click", ".open", function () {
var inde = $("table tbody tr td:nth-child(4)").text();
console.log(inde);
});
Thank for help
Try to use .parent() along with .prev() to get your required data,
$(document).on("click", ".open", function () {
var inde = $(this).parent("td").prev().text();
console.log(inde);
});
If your html is having a tbody as a static node then you could use .tbody in the place of document.
I have a table and if I click a button i want to take the value from charge_outstanding_NUM and set charge_receipt_NUM to it. I need a reusable script because I will not know how many rows will get posted through.
<table>
<thead>
<tr>
<th>ID</th>
<th>Value</th>
<th>Outstanding</th>
<th>Reciept</th>
</tr>
</thead>
<tbody>
<tr>
<td>001</td>
<td>150.00</td>
<td id="charge_outstanding_1">150.00</td>
<td><input type="text" name="charge_receipt_1" id="charge_receipt_1" value=""></td>
</tr>
<tr>
<td>002</td>
<td>10.00</td>
<td id="charge_outstanding_2">10.00</td>
<td><input type="text" name="charge_receipt_2" id="charge_receipt_2" value=""></td>
</tr>
<tr>
<td>003</td>
<td>250.00</td>
<td id="charge_outstanding_3">250.00</td>
<td><input type="text" name="charge_receipt_3" id="charge_receipt_3" value=""></td>
</tr>
</tbody>
</table>
My jquery isn't working and I am not sure why. I click the button then loop through each col that starts with 'charge_outstanding_' then take the value and assign it to the closest input which is within the same row.
$('#pay_in_full').click(function(){
$("[id^=charge_outstanding_]").each(function(){
charge = $(this).val();
$(this).closest('input').val(charge);
});
});
working JSfiddle: http://jsfiddle.net/F5NvW/2/
Issue with your code: charge = $(this).val(); you are finding td which has no value, you need .html() for this
$(document).on("click", "#pay_in_full", function() {
$("[id^=charge_outstanding_]").each(function(){
var charge = $(this).html();
$(this).next().find('input').val(charge);
});
});
Suggestion: use class name with each <td> like this
Jsfiddle: http://jsfiddle.net/F5NvW/
Note: less error prone..
$(document).on("click", "#pay_in_full", function() {
$(".outstanding").each(function(){
var charge = $(this).html();
$(this).next().find('.paidAmount').val(charge);
});
});
.Closest will search for the ancestor elements, In your case the target input is the children of the next sibling of the selected element. So you have to use .find() or .children() to select that.
Try,
$('#pay_in_full').click(function(){
$("[id^='charge_outstanding_']").each(function(){
charge = parseInt($(this).text());
$(this).next().find('input').val(charge);
});
});
Additionally, You are selecting a td element, so you have to use .text() to get its text not .val()
DEMO
This is the HTML:
<table id="tblTestAttributes">
<thead>
<tr> <th>Head 1</th> <th>Head 2</th> </tr>
</thead>
<tbody>
<tr> <td id="txtDesc">Item 1</td> <td id="ddlFreq">Assume a DropDownList Here</td> </tr>
<tr> <td id="txtDesc">Item 1</td> <td id="ddlFreq">Assume a DropDownList Here</td> </tr>
<tr> <td id="txtDesc">Item 1</td> <td id="ddlFreq">Assume a DropDownList Here</td> </tr>
</tbody>
</table>
This is the javascript to get the values of each row:
var frequencies = [];
if ($('#tblTestAttributes').length) {
$('#tblTestAttributes tr').each(function () {
var t = $(this).find('td[id^="txtDesc"]').text() + ";" + $(this).find('[id^="ddlFreq"] option:selected').val();
alert(t);
frequencies.push(t);
});
}
I want to avoid the first row, which contains th elements which are just display headers and don't contain any data.
So I changed the selector to this:
#tblTestAttributes tr:not(:first-child)
This is skipping the second tr as well. What is happening here?
Simple you can use below code
$('#tblTestAttributes tr:not(:has(th))').each(function () {
In terms of performance, using .find() will be better than resolving the selector with Sizzle.
$('#tblTestAttributes').find('tbody').find('tr').each(function () { ... });
Here's the jsPerf to show it.
use
#tblTestAttributes tr:gt(0)
or
#tblTestAttributes tbody tr
I would recommend the 2nd, because it may take advantage of querySelectorAll and should be the fastes solution.
your approach didn't work as expected, because the 2nd tr is also a first-child(of tbody)
Use tr + tr selector, which gets all tr that appear after another tr, so the first one is skipped.
Also no need to check if table exists, as in that case $.each wouldn't even get executed.
var frequencies = [];
$('#tblTestAttributes tr + tr').each(function () {
var t = $(this).find('td[id^="txtDesc"]').text() + ";" + $(this).find('[id^="ddlFreq"] option:selected').val();
alert(t);
frequencies.push(t);
});
After your edit:
Simply select only all tr inside tbody:
$('#tblTestAttributes tbody tr').each(function(){
...
}
It happens because the second row is, in fact, the first child of the tbody just like the first row is the first child of the thead.
To only take the elements you need, I'd suggest something nearer from your need :
#tblTestAttributes tr:has(td)
Don't forget to get rid of those duplicate txtDesc id, this is illegal in HTML, use a class instead.
Scenario:
I'm using datatable library to display alot of information. That table have the following rows:
Id Type Name Case
What I'm looking for is that when I click the second row Type, that value will be taking and pasted in a textbox
Example
Id Type Name Case
1 text Juan 20001
3 List Pedro 20005
If I click the row that has the id # 1, I need to take the Type innerHTML. Does not matter what apart of the row I click just take the second td's html.
I tried with this code:
$("tr td").click(function () {
alert($(this).html());
})
It worked great, But the problem is that the user have to click exactly the row Name, but would be better if user can click over any of the row and just take the second rows html.
Suggesstions?
myRow.getElementsByClassName('td')[1].innerHTML
should get you the innerHTML of the second table cell of myRow as long as the first table cell does not contain a nested table.
You might try adding the click handler to the rows instead of to the cells too.
Try using eq()
but would be better if user can click over any of the row and just
take the second rows html.
$("tr td").click(function () {
secondrow = $(this).closest('tr').siblings().eq(1);
});
If i click the row that has the id # 1, i need to take the Type
innerHTML. Does not matter what apart of the row i click just take the
second td's html.
$("tr td").click(function () {
secondTd = $(this).siblings().eq(1);
alert(secondTd.html());
});
Try this
$(function () {
$("#thetable tr").click(function () {
if ($(this).index() == 0) return;
$('#tbox').val($('td:nth-child(2)', $(this)).html())
})
});
HTML
<table border="1" cellpadding="4" id="thetable">
<tr>
<td>Id</td>
<td>Type</td>
<td>Three</td>
<td>Four</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
</tr>
<tr>
<td>5</td>
<td>6</td>
<td>7</td>
<td>8</td>
</tr>
</table><br />
<input type="text" name="tbox" id="tbox" />
It method takes into account the first row that contains only labels and doesn't set the textbox value to a label if top row is clicked.
