Find auto generated id of textbox on button click

<td id="RB_0_val_1">
<label for="RB_0_value_field_1" style="display:none;">Field Value</label>
<input type="text" id="RB_0_value_field_1"></td>
<td id="RB_0_extra_1"><input type="button" value="Select.." id="File"></td>
Now i need to find the id of textbox on th click of button.So i am using
var textboxid=$('input[id="File"]').closest('input[type="text"]').attr("id");
but value returned is undefined.
The id of the textbox is auto generated so i need to find the id on the click of the button.
How to do this?

Please replace your code with my code where just add prev() function.
var textboxid=$('input[id="File"]').prev().closest('input[type="text"]').attr("id");

Try utilizing .parentsUntil , :has()
$("#File").click(function() {
var textboxid = $(this).parentsUntil("td:has(:text)").find(":text").attr("id")
console.log(textboxid)
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table>
<tbody>
<tr>
<td id="RB_0_val_1">
<label for="RB_0_value_field_1" style="display:none;">Field Value</label>
<input type="text" id="RB_0_value_field_1">
</td>
<td id="RB_0_extra_1">
<input type="button" value="Select.." id="File">
</td>
</tr>
</tbody>
</table>

You can use jquery .prev() api, for doing that. Try the FIDDLE
Javascript code
$(document).ready(function(){
$('#File').click(function(e){
console.log($(this).prev('input[type=text]').prop('id'));
alert($(this).prev('input[type=text]').prop('id'));
e.preventDefault();
});
});
EDIT : For Updated markup provided in FIDDLE, I have used .closest() .prev() and .find() jquery api
$(document).ready(function () {
$('#File').click(function (e) {
var id = $(this).closest('td').prev('td').find('input[type=text]').prop('id');
alert(id);
e.preventDefault();
});
});
Hope this helps .....

I assume that the tds are inside a tr.
You can make this selector
var textboxid=$('input#File').parents('tr').find('label + input').attr("id");

Try this maybe (haven't tried it) :
var textboxid = $('#File').parent().find('input[type=text]').first().attr("id");
Should it be triggered by a click or something ?

Problem is the text box is in different td, try this:
$(function() {
$('#File').on('click', function() {
alert($(this).parent().prev('td').children('input[type=text]').prop('id'));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<table>
<tr>
<td id="RB_0_val_1">
<label for="RB_0_value_field_1" style="display:none;">Field Value</label>
<input type="text" id="RB_0_value_field_1">
</td>
<td id="RB_0_extra_1">
<input type="button" value="Select.." id="File">
</td>
</tr>
</table>

FIDDLE
$$(document).on('click', '#File', function() {
var qwe = $(this).parent().parent().find('input[type="text"]');
alert(qwe.attr('id'));
});

How can I automatically generate a new input field when a certain input field is navigated to?

Inspired by the Chrome Postman extension, I want to implement a multi-field form section by automatically adding a new input field when a certain field is navigated to, and give focus to the new field. The below screenshot shows how this works in Postman; the down-most row contains a couple of inputs that, when navigated to, results in a new row being added above it, which can be typed into.
How can I achieve this behaviour in JavaScript/jQuery? To simplify matters, I need only one input field per row. I've created a fiddle that should serve as a starting point for a solution.
Example HTML:
<div id="last-row">
<input name="multifield" placeholder="Value"></input>
</div>
​

See how I'd do it: http://jsfiddle.net/jCMc8/8/
html:
<section>
<div id="initRow">
<input name="multifield" placeholder="Value">
</div>
</section>​
javascript:
function addRow(section, initRow) {
var newRow = initRow.clone().removeAttr('id').addClass('new').insertBefore(initRow),
deleteRow = $('<a class="rowDelete"><img src="http://i.imgur.com/ZSoHl.png"></a>');
newRow
.append(deleteRow)
.on('click', 'a.rowDelete', function() {
removeRow(newRow);
})
.slideDown(300, function() {
$(this)
.find('input').focus();
})
}
function removeRow(newRow) {
newRow
.slideUp(200, function() {
$(this)
.next('div:not(#initRow)')
.find('input').focus()
.end()
.end()
.remove();
});
}
$(function () {
var initRow = $('#initRow'),
section = initRow.parent('section');
initRow.on('focus', 'input', function() {
addRow(section, initRow);
});
});
​
​

This is how I would do it.
HTML:
<table>
<tbody>
<tr class="item">
<td><input name="multifield" placeholder="Value" /></td>
<td><i class="icon delete"></i></td>
</tr>
<tr class="item inactive">
<td><input name="multifield" placeholder="Value" /></td>
<td><i class="icon delete"></i></td>
</tr>
</tbody>
</table>
JavaScript:
$("table")
.on("click focus", ".item.inactive", function(e) {
var curRow = $(this);
curRow.clone().appendTo("table tbody");
curRow.removeClass("inactive").find("input:first").focus();
})
.on("click", ".icon.delete", function(e) {
$(this).closest("tr").remove();
});
See test case on jsFiddle.

I have come up with a solution that seems to work so far, but I'm interested in hearing from others as to whether it is a good one. What I do is catch the focus event for the last input field, add a new row and give focus to the input field within that row. See this fiddle for working code.
HTML:
<div id="last-row">
<input name="multifield" placeholder="Value">
</div>
JavaScript:
var lastRow = $('#last-row');
var lastInput = lastRow.find('input');
function addRow() {
var newRow = $('<div><input name="multifield" placeholder="Value"><a class="row-delete"><img src="http://i.imgur.com/ZSoHl.png" /></a></div>');
var newInput = newRow.find('input');
lastRow.before(newRow);
newInput.focus();
var newDelete = newRow.find('a');
newDelete.click(function() {
newRow.remove();
});
}
lastInput.focus(function() {
addRow();
});

Jquery Each Input Within DIV (Has A Table)

Im currently trying to get all input elements from a DIV.
$("[required]").each(function() {
});
I have this code which returns every element with a required attribute.
I know within the function of that each() I can use each item like:
$(this)
So I get the div ID's shown below, and try to get all the inputs from it via:
var id = $(this).attr('id');
console.log("### " + id);
console.log($("#" + id + " > :input").length);
Which returns 0 when I have 4 in put elements within that DIV (also theres a table in the div).
What I would ideally like to do is for each input element within my div, print its ID.
UPDATED
<div id="contactAddress" required="true">
<td>Addres line 1:</td>
<td colspan="2">
<input type="text"/>
</td>
<td>Addres line 2:</td>
<td colspan="2">
<input type="text" />
</td>
</tr>
</div>
console.log($(this).html());
Shows nothign but if i add anythign outsire the or like below...
<div id="contactAddress" required="true">
<input type="text" />
And run console.log($(this).html()); It shows it put not the table?
Any ideas im using Jquery Mobile

This below will find all inputs inside the div element. It will then leave a log of the id of this element.
$("div > input").each(function() {
console.log( $(this).attr("id") );
});
if you need the div id containing the inputs you could use .parent()
$("input").each(function() {
console.log( $(this).parent().attr("id") );
});

jQuery to get Hidden Field Value in Table Row

I have a table with a hidden field in each row. I need to Alert the value of hidden field when a button in that row is clicked. I have the following jQuery code. But it does not work. How do we make it work?
CODE: http://jsfiddle.net/Lijo/xWanB/
<script>
$(document).ready(function () {
//"Show ID" for Associate Button Click
$('.resultGridTable tr > td > .actionButtonNational').click(function () {
//"this" means show ID button
//Traversing to get the parent row and then the required columns in the row
var associateID = $(this).parents('tr:first > .wrapperDivHidden input[type=hidden]').val();
alert(associateID);
return false;
});
});
</script>
HTML
<td>
XXXXX
<input type="submit" name="ctl00$detailContentPlaceholder$grdSubscribedAssociates$ctl04$btnNational"
value="Show ID" id="detailContentPlaceholder_grdSubscribedAssociates_btnNational_2"
class="actionButtonNational" style="color: White; background-color: #A7A7A6;
font-weight: bold; width: 60px" />
<div id="wrapperDivHidden" class="wrapperDivHidden">
<input type="hidden" name="ctl00$detailContentPlaceholder$grdSubscribedAssociates$ctl04$hdnAssociateID"
id="detailContentPlaceholder_grdSubscribedAssociates_hdnAssociateID_2"value="789345680" />
</div>
</td>

your selector starts with tr:first > .wrapperDivHidden ... but .wrapperDivHidden is not an immediate child of tr so change your selector like so:
$(this).parents('tr').find('.wrapperDivHidden input[type="hidden"]').val();
Fiddle: http://jsfiddle.net/xWanB/3/

Try this:
<script type="text/javascript">
$(document).ready(function () {
//"Show ID" for Associate Button Click
$('.actionButtonNational').click(function () {
var associateID = $('input[type=hidden]', $(this).closest("td")).val();
alert(associateID);
return false;
});
});
</script>

Here is an over simplified example of what you are trying to do:
http://jsfiddle.net/6S5rD/

if the first column of your row is hidden then use this
var x = $('input[type=hidden]', $(this).find("td:first")).val();

trouble with jquery and traversing the DOM to select the appropriate elements

Hello guys i have the below html for a number of products on my website,
it displays a line with product title, price, qty wanted and a checkbox called buy.
qty input is disabled at the moment.
So what i want to do is,
if the checkbox is clicked i want the input qty to set to 1 and i want it to become enabled.
I seem to be having some trouble doing this. Could any one help
Now i can have multiple product i.e there will be multiple table-products divs within my html page.
i have tried using jQuery to change the details but i dont seem to be able to get access to certain elements.
so basically for each table-product i would like to put a click listener on the check box that will set the value of the input-text i.e qty text field.
so of the below there could be 20 on a page.
<div class="table-products">
<div class="table-top-title">
My Spelling Workbook F
</div>
<div class="table-top-price">
<div class="price-box">
<span class="regular-price" id="product-price-1"><span class="price">€6.95</span></span>
</div>
</div>
<div class="table-top-qty">
<fieldset class="add-to-cart-box">
<input type="hidden" name="products[]" value="1"> <legend>Add Items to Cart</legend> <span class="qty-box"><label for="qty1">Qty:</label> <input name="qty1" disabled="disabled" value="0" type="text" class="input-text qty" id="qty1" maxlength="12"></span>
</fieldset>
</div>
<div class="table-top-details">
<input type="checkbox" name="buyMe" value="buy" class="add-checkbox">
</div>
<div style="clear:both;"></div>
</div>
here is the javascript i have tried
jQuery(document).ready(function() {
console.log('hello');
var thischeck;
jQuery(".table-products").ready(function(e) {
//var catTable = jQuery(this);
var qtyInput = jQuery(this).children('.input-text');
jQuery('.add-checkbox').click(function() {
console.log(jQuery(this).html());
thischeck = jQuery(this);
if (thischeck.is(':checked'))
{
jQuery(qtyInput).first().val('1');
jQuery(qtyInput).first().prop('disabled', false);
} else {
}
});
});
// Handler for .ready() called.
});

Not the most direct method, but this should work.
jQuery(document).ready(function() {
jQuery('.add-checkbox').on('click', function() {
jQuery(this)
.parents('.table-products')
.find('input.input-text')
.val('1')
.removeAttr('disabled');
});
});

use
jQuery('.add-checkbox').change(function() {
the problem is one the one hand that you observe click and not change, so use change rather as it really triggers after the state change
var qtyInput = jQuery(this).children('.input-text');
another thing is that the input is no direct child of .table-products
see this fiddle

jQuery('input:checkbox.add-checkbox').on('change', function() {
jQuery(this)
.parent()
.prev('div.table-top-qty')
.find('fieldset input:disabled.qty')
.val(this.checked | 0)
.attr('disabled', !this.checked);
});

This should get you started in the right direction. Based on jQuery 1.7.2 (I saw your prop call and am guessing that's what you're using).
$(document).ready(function() {
var thischeck;
$('.table-products').on('click', '.add-checkbox', function() {
var qtyInput = $(this).parents('.table-products').find('.input-text');
thischeck = $(this);
if (thischeck.prop('checked')) {
$(qtyInput).val('1').prop('disabled', false);
} else {
$(qtyInput).val('0').prop('disabled', true);
}
});
});
Removing the property for some reason tends to prevent it from being re-added. This works with multiple tables. For your conflict, just replace the $'s with jQuery.
Here's the fiddle: http://jsfiddle.net/KqtS7/5/
