I want to assign a hidden td value to a id javascript variable. I used id = $(e.target).closest('tr').find('.orderid').val() line to do this. but it not works. Please help me to solve this.
<tr>
<td class="orderid" style="display:none;" value="{{this.id}}"/>{{this.id}}</td>
</tr>
On this line value attribute is not valid for a td element :
<td class="orderid" style="display:none;" value="{{this.id}}"/>{{this.id}}</td>
Should use this (if i understand correctly) :
<td class="orderid" style="display:none;" id="{{this.id}}"/>{{this.id}}</td>
Then if you need to retrieve this id :
id = $(e.target).closest('tr').find('.orderid').attr('id');

A short question: i use a usually html + twig table which i fill with a lot values. The important part of this table looks like that:
{% if rec.pDsDuplicate =='0'%}
<td class="PFu1Exists">
{{rec.getPFu1Exists()}}
</td>
<td class ="PFu2Exists">
{{rec.getPFu2Exists()}}
</td>
<td class ="PFu3Exists">
{{rec.getPFu3Exists()}}
</td>
<td class= "PFu5Exists">
{{rec.getPFu5Exists()}}
</td>
<td class ="PSdqExists">
{{rec.getPSdqExists()}}
</td>
<td class="PFupExists">
{{rec.getPFupExists()}}
</td>
{% else %}
Now i use this function to select a row:
$("#search_results tr").click(function() {
$(this).addClass("selected").siblings().removeClass("selected");
});
after the selection, the row belongs to the class "selected".
Now my specify question: How i can get the value from the column with using the class/ID Attribut e.g PFu1Exists from the selected row.
of course, i can iterate about the row and compare, but im looking for a quick an short JQuery line.
during reading some posts here, i found the function closest and find, but how i have to write the statement that i can be shure!, that the query is just searching in the selected row.. ? and not will traverse up and down to the next row?
value= $(.selected).closest(.selected).find('.PFu1Exists');
thanks for your time!
with your click function, you already remove other selected classes. that means, within your table, there is only 1 tr that has selected class. So, You can just use it like :
$('.selected').find('.PFu1Exists');
by using find(), you will only search through its child / descendants. it wont find its siblings. you can read more from
You can use following code for this..
$("#search_results tr").click(function(){
$(this).addClass("selected").siblings().removeClass("selected");
alert($(this).find('.PFu1Exists').html());
});
OR you can use -
alert($('tr.selected').find('.PFu1Exists').html());
You don't need to use find() function to search inside <tr>.
you can directly use
$('.selected .PFu1Exists')
which will select the child <td class='PFu1Exists'> inside <tr class='selected'>.
This is my code:
<tbody>
{#participants}
<tr>
<td id="id">{.fullName}</td>
</tr>
{/participants}
I am writing this code in .dust file. I want to append row index value to my td's ID. Is there any way to do it? Thanks in advance!
Do you want the index from your database row? Then you might want to to something like:
<td id="id_{.id}">{.fullName}</td>
...where {.id} contains the value of the ID of the row. this would be the best method, as it required no javascript, this method is fastest.
{$idx} will give you the current index.
Example
<tr>
<td id="id_{$idx}">{.fullName}</td>
</tr>
I create dynamic a table in javascript. A row looks like this
<td id="user[i]['id']">user[i]['name']</td>
So I need the value user[i]['id'] which represents the id of <td> or <input>.
How could I get the id ?
You can get the attribute value with the following:
document.getElementsByTagName("td")[0].id;
Given,
<table id=ThisTable>
<tbody>
<tr>
<td id="ThisCell">
</td>
</tr>
<tr>
<td id="NotThis">
</td>
</tr>
<tr>
<td id="NorThis">
</td>
</tr>
</tbody>
</table
How can I use JQuery/Javascript to assign the ID of the first table cell in #ThisTable to the variable "Selected"?
The result in this case should look like:
var Selected = "ThisCell";
I need to get the first cell's ID without having any knowledge of what the ID is, probably using the :first selector. In addition, this isn't the only table on the page, so it must be referenced with its ID.
var Selected = $('#ThisTable td:first').attr('id');
This selects the first td element that is a descendant of the element with ID ThisTable, returns its id attribute and assigns it to Selected.
JSFiddle
Just:
$("#ThisTable tbody tr:first td:first").attr("id");
This code gets the first td of your table, then stores its id in a variable Selected.
var Selected = document.querySelector("#ThisTable td").id;
Pure DOM methods, fastest method here, and works on 91.71% of browsers according to Can I use.
$(function () {
console.log($($('#ThisTable').find('td')[0]).attr('id'))
});

I have the div structure shown below. For the second <td> in the table i want to replace with a hyperlink whose href attribute is stored in the variable myLink.
How can i do this with jquery ?
Please help.
Thank You.
<div class="pbHeader">
<table cellspacing="0" cellpadding="0" border="0">
<tbody>
<tr>
<td class="pbTitle">
<h2 class="mainTitle">Transfer Membership</h2>
</td>
<td>
</td>
</tr>
</tbody>
</table>
</div>
You can do something like this:
// you said this was already set
var myLink = 'http://stackoverflow.com/questions/2761234';
var $a = $('<a>').attr('href',myLink).text('My Link!');
$('.pbHeader td:eq(1)').empty().append($a);
This uses the :eq() selector to grab the second TD underneath a .pbHeader (:eq is zero based, so 0 is the first element, 1 is the second element). It empties your and appends the generated <a> tag inside of it.
You could also do this:
$('.pbHeader td:eq(1)').html('My Text!');
Which sets the innerHTML of that <td> to be your "link"
