How to get text of next td in jQuery?

I need Test 2 text when I clicked on "Click". I have tried like this ...
$("#clicked").click(function(){
alert( $('this').closest('td').next('td').next('td').text());
})
But In alert there is empty. How I can get Test 2 ?
<tr>
<td> </td>
<td><a id = 'clicked'>Click</a></td>
<td>Test 1</td>
<td><a id = 'clicked2' /> Test 2</a></td>
</tr>
From comment below:
this means $('#clicked'). That means when I clicked on the Click link.

you need to use parent instead of closest :
$("#clicked").click(function(){
text = $(this).parent().next('td').next('td').text();
alert(text);
})
https://jsfiddle.net/g6gnog4h/

$('#clicked').click(function(){
console.log($(this).closest('td').next().text());
});

Try this one, as you need to go parent tr and than find the 4th td with the ID of a tag to get the text.
<table><tr>
<td> </td>
<td><a id = 'clicked'>Click</a></td>
<td>Test 1</td>
<td><a id = 'clicked2' /> Test 2</a></td>
</tr>
</table>
<script>
$('#clicked').click(function(){
alert($(this).parents('tr').children().find('#clicked2').text());
});
</script>

You may try like this:
$('#clicked').click(function(){
var val=$(this).siblings().text();
alert(val);
});
siblings() method returns all sibling elements of the selected element.

jQuery selector when a table is created dynamically

I have a table (generated at run time) and a dropdown. Before the page is up, the table does not exist. Once the page is up, the table and the dropdown look similar to this fiddle:
$("#aDropDown").val($("WhatToPutHere?").text());
I am trying to do the following: when the user select the Select button, I need the dropdown selected item to match the Type for the row.
Any example would be appreciated.
Thanks

first, you have multiple button with the same id. They should share a class.
<button class="aButton">Select</button>
next, what you want is the .text() of the prev <td>
$('.aButton').on('click', function() {
var type = $(this).closest('td').prev('td').text();
$("#aDropDown").val(type);
});
JSFIDDLE
as #Mackan pointed out, you might encounter a problem if you're not using a
delegated event, as you're creating the table dynamically. in that case the following code would work better :
$(body).on( 'click', '.aButton' , function() {
var type = $(this).closest('td').prev('td').text();
$("#aDropDown").val(type);
});

$('.aButton').click(function(e) {
var btn = $(e.target);
$("#aDropDown").val(btn.data('category'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<thead>
<td>item</td>
<td>Type</td>
<td>Action</td>
</thead>
<tr>
<td class="anItem">Apple</td>
<td class="aType">Fruit</td>
<td>
<button class="aButton" data-category="Fruit">Select</button>
</td>
</tr>
<tr>
<td class="anItem">Orange</td>
<td class="aType">Fruit</td>
<td>
<button class="aButton" data-category="Fruit">Select</button>
</td>
</tr>
<tr>
<td class="anItem">collard</td>
<td class="aType">Veggie</td>
<td>
<button class="aButton" data-category="Veggie">Select</button>
</td>
</tr>
</table>
<br/>
<br/>aDropDown:
<select id="aDropDown">
<option value="Fruit">Fruit</option>
<option value="Veggie">Veggie</option>
</select>
Removed id attribute from each button (id should be use for unique elements).
Added aButton class to each button.

As I said above, your code must run on some event. Here's how I'd do it with minimal markup changes (just a class on the buttons):
$('.selectBtn').click(function() {
var myVal = $(this).closest('tr').find('.aType').text();
console.log(myVal);
$("#aDropDown").val(myVal);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<thead>
<td>item</td>
<td>Type</td>
<td>Action</td>
</thead>
<tr>
<td class="anItem">Apple</td>
<td class="aType">Fruit</td>
<td>
<button id="aButton" class="selectBtn">Select</button>
</td>
</tr>
<tr>
<td class="anItem">Orange</td>
<td class="aType">Fruit</td>
<td>
<button id="aButton" class="selectBtn">Select</button>
</td>
</tr>
<tr>
<td class="anItem">collard</td>
<td class="aType">Veggie</td>
<td>
<button id="aButton" class="selectBtn">Select</button>
</td>
</tr>
</table>
<br/>
<br/>aDropDown:
<select id="aDropDown">
<option value="Fruit">Fruit</option>
<option value="Veggie">Veggie</option>
</select>

Since you said your table is created dynamically, you should use a bind to a persistent element, using a delegated event (like document or body):
Delegated events have the advantage that they can process events from descendant elements that are added to the document at a later time. By picking an element that is guaranteed to be present at the time the delegated event handler is attached, you can use delegated events to avoid the need to frequently attach and remove event handlers
All of the other answers (time of writing) uses binds that will add the event handlers to the actual buttons. This means that if the button doesn't exist, or gets temporarily removed, the bind will be lost or can't be created to start with.
Using a delegated event:
$(document).on('click', '.aButton', function() {
or..
$('body').on('click', '.aButton', function() {
Also notice that the above binds use a class selector, .aButton, because id's must be unique (and yours were not).
<button class="aButton">Select</button>
Full example at jsFiddle:
$(document).on('click', '.aButton', function() {
$("#aDropDown").val($(this).parent().prev('td').text());
});
Edit:
If the table structure is in danger of changing (adding more td's or tr's), the below script will be better at finding the correct td (by class .aType):
$(document).on('click', '.aButton', function() {
$("#aDropDown").val($(this).closest('tr').find('.aType').text());
});

Jquery how to retrieve / replace value in <span> <tr> <td> value?

There are more than one TR TD, same class name given in a table used for formatting without ID given.
I would like to seek help for jQuery. How can I retrieve / replace <td> content in the span id = payment_currency_text, class="formdata element?
1) To set a variable, store as SGD, getting from second set of TR TD.
2) Replace SGD to EUR.
Note : The system used Jquery version = v1.4.2
I tr to used below syntax but no luck :
alert(jQuery("#payment_currency_text tr.find(.formdata)").val());
alert(jQuery("#payment_currency_text").next('.formdata').val());
alert(jQuery("#payment_currency_text tr td.formdata").val());
alert(jQuery("#payment_currency_text").find(".formdata").html());
... (tr td child)
<tr>
<td class="prompt" align="left">
Region*
</td>
<td class="formdata" align="left">
Asian
</td>
</tr>
<span id ="payment_currency_text"> <!--- There is a SPAN tag, with ID given --->
<tr>
<td class="prompt" align="left">
Payment currency*
</td>
<td class="formdata" align="left">
SGD <!--- How i can set a variable to hold SGD, then replace to EUR? --->
</td>
</tr>
</span>

to target td.formdata inside span.Try this:
To get:
var currency=$('#payment_currency_text .formdata').html();//currency will be SGD here
To set:
$('#payment_currency_text .formdata').html('EUR');

If you know that its always going to be a specific child you can use the :nth-child() selector.
var setter = $("tr:nth-child(2) td:nth-child(2)").text();
$("tr:nth-child(2) td:nth-child(2)").text("EUR");
alert(setter)
Here is a fiddle http://jsfiddle.net/87V9v/

In jQuery you can replace the inner HTML of an element like so
$('.class-name').html("Some html in here");
However, be careful because this will replace the HTML for all classes of this name.

You can use text() to get the data (plain text) as well as replace existing data with new one. If your replacement is HTML, you can use html()
var data=$('td.formdata').text();
alert("The value is"+data);
$('td.formdata').text("New Data");

You can use:
$("#payment_currency_text").text("your text");
or
$("#payment_currency_text").html("your<b>text</b>");

If you just want to change the html inside the td, use like this
$(".formdata").html("some text or tags here");
If you want to get the text inside those td, use like this
$(".formdata").each(function(){
$(this).html();
});
Edit
$("#payment_currency_text").find(".formdata").html()
$("#payment_currency_text").find(".formdata").html("some text or tags here");
Your html structure has some problem, you cant enclose tr inside span. tr should be the child of table. So change your html accordingly.
<table>
<tr>
<td class="prompt" align="left">
Region*
</td>
<td class="formdata" align="left">
Asian
</td>
</tr>
<tr id="payment_currency_text">
<td class="prompt" align="left">
Payment currency*
</td>
<td class="formdata" align="left">
SGD
<!--- How i can set a variable to hold SGD, then replace to EUR? --->
</td>
</tr>
</table>
Then you can use the above code for getting the elements and values.

jQuery replace and add new element

I have the following HTML
<tbody class="t_bdy">
<tr class="Quotation_List_td">
<td class="item"><a class="button2 crm_insert" href="#">Insert</a><a class="button2 crm_delta" href="#">Delete</a></td>
<td class="Quotation_List_ItemTD description"> </td>
<td class="quantitiy"> </td>
<td class="unit_price"> </td>
<td class="discount"> </td>
<td class="total"> </td>
</tr>
<tr class="Quotation_List_td">
<td class="item"><a class="button2 crm_insert" href="#">Insert</a><a class="button2 crm_delta" href="#">Delete</a></td>
<td class="Quotation_List_ItemTD description"> </td>
<td class="quantitiy"> </td>
<td class="unit_price"> </td>
<td class="discount"> </td>
<td class="total"> </td>
</tr>
</tbody>
I need to insert new <tr> when I click on button with .crm_insert class.
When .crm_insertis clicked, it need to insert a new row at the current location. All
other rows will move down. For example, if insert against row 3 is clicked then
row 3 will be new row inserted and current row 3 etc will move down to become
row 4 etc.
How can I achieve this ?
All answers are good, but I can only accept one : Thanks all

I'd try something like this using closest() and before()
$('a.crm_insert')
.click(function()
{$(this).closest('tr.Quotation_List_td').before(htmlcodeofyounewTRhere);}
)
Hope this will help

Assuming:
Your new row is in the same structure as your current row
You want the new row to also have the 'Insert' functionality
You want a click event handler which does something to this effect:
$('.crm_insert', '#table').on('click', function() {
var currentRow = $(this).closest('tr');
currentRow.clone(true).insertBefore(currentRow);
});
Where #table is the id of your table.
Here's a simple example
If you are inserting something completely different, then you do not need to use on() or clone(), and the code becomes simpler:
$('.crm_insert').click(function() {
var currentRow = $(this).closest('tr');
$('<tr />').insertBefore(currentRow);
});
Where <tr /> would be whatever you are trying to insert.

This might work for you. It'll find the parent tr of the button you just clicked, clone it (including the onClick functionality of the button) and insert that before the parent tr. This will result in a new row containing the same information as the target row though. Depending on what results you want to show in the new row, you might want to alter the code to clear out any copied values too.
$(".crm_insert").live("click", function(){
var tr = $(this).parents("tr.Quotation_List_td");
tr.clone().insertBefore(tr);
});

You can try this
$('.crm_insert').live('click', function(){
var self = $(this);
self.parents('tr.Quotation_List_td').before('add your row here');
});
The latest versions of jquery employ on instead of live.

hide/show not working properly with jquery

I have a page with three rows of main information that all have a 'More Info' button attached, sort of like wefollow.com and their info button.
When the 'More Info' link is clicked a <tr> with a class of "mi" slides down above the main info.
The problem that I am getting is hiding the <tr> before the 'More Info' link is clicked. There is just a blank space where the <tr> is. The info in the <tr> is being hidden with jQuery (script below) and then displays when 'More Info' is clicked.
I tried hiding the "mi" with CSS but when the 'More Info' button is clicked, nothing happens.
Any help would be awesome. Thanks.
Scripts
index
<table>
<tbody>
<tr id="info-1"> </tr>
<tr class="mi">
<td>
<div id="1" class="more-information" />
</td>
</tr>
<tr class="">
<td> </td>
<td> </td>
<td> <a id="1" class="more-info" href="#">More info</a> </td>
</tbody>
</table>
listing.js
$(function(){
$(".more-information").hide();
$(".more-info").click(function () {
var divname= this.id;
$("#"+divname).load("getinfo.php").slideToggle("slow").siblings().hide("slow");
return false;
});

First problem is you're repeating IDs. They need to be unique. That's no doubt throwing off your code.
<table>
<tbody>
<tr id="info-1"> </tr>
<tr class="mi">
<td><div id="more-1" class="more-information">More information</div></td>
</tr>
<tr>
<td></td>
<td></td>
<td><a id="1" class="more-info" href="#">More info</a></td>
</tr>
</tbody>
</table>
combined with:
$(function() {
$("a.more-info").click(function() {
$("#more-" + this.id).load("getinfo.php").slideToggle("slow").siblings().hide("slow");
});
});
Not sure why you need to hide siblings in the above though.
Also, I wouldn't hide the "more-information" divs in jquery. Just add CSS for that:
div.more-information { display: none; }

You are hiding the more-information div but you are not hiding its parent element, the <tr> with class mi. Try putting the id attribute in the <tr> instead of the enclosed div, and hiding the whole row. Also, you'll have to take cletus' advice about not repeating id's and unnecessary sibling hiding.
