How do I look for the TD inside a TR that is below the TR that I click?

The purpose of this code is to make an ajax call if the <td> contained within the <tr> that is below the <tr> that was clicked, but only if the hidden <tr> is empty. Eventually I plan to take that data and do something with it, but for right now, I just need to get this thing which emulates an accordion as a table working. Due to this table being made on the same html file that I have other .hidden elements on, I had to create custom classes to hide these particular ones. The class detail-view makes it visible, and the class hidden-detail contains display:none. I know that postDetails works as far as finding the right data. What i'm more worried about is finding out why FireFox's dev tools say statusRow and detPane are marked as (unavailable) throughout this code, whereas statusRow.closest('tr').next('tr') actually appears to contain the row detPane, as intended. Is there something wrong with the jQuery or selectors? What's going on here?
function makeOrderTable(response, username, sesstoken) {
$(jQuery.parseJSON(JSON.stringify(response))).each(function() {
var foNum = this['Factory Order#'];
var pO = this['PO#'];
var status = this['Status'];
var shipDate = this['Ship Date'];
$('.orders tbody').append(
'<tr class="status-row">'+
'<td>' + foNum + '</td><td>' + pO + '</td><td>' + status + '</td><td>' + shipDate + '</td>'+
'</tr>'+
'<tr class="detail-row hidden-detail">'+
'<td colspan="4"></td>'+
'</tr>'
);
});
$(document).ready(function() {
$('table').on('click', 'tr.status-row', function() {
var statusRow = $(this);
var detPane = $(statusRow[0]).closest('tr').next('tr');
$('.detail-view').addClass('hidden-detail');
$('.detail-view').removeClass('detail-view');
detPane.addClass('detail-view');
detPane.removeClass('hidden-detail');
if (detPane.find('td').text == '')
{
var value = statusRow.find('td:first-child').text();
postDetails(value, username, sesstoken, detPane.find('td'));
}
});
});
}

The problem was that as epascarello pointed out, text isn't a valid property. Ergo, couldn't find anything. But, I also needed to grab the details td separately--i.e. couldn't access things from other things and just daisy-chain selectors all over the place. So, here's the end result.
function makeOrderTable(response, username, sesstoken) {
$(jQuery.parseJSON(JSON.stringify(response))).each(function() {
var foNum = this['Factory Order#'];
var pO = this['PO#'];
var status = this['Status'];
var shipDate = this['Ship Date'];
$('.orders tbody').append(
'<tr class="status-row">'+
'<td>' + foNum + '</td><td>' + pO + '</td><td>' + status + '</td><td>' + shipDate + '</td>'+
'</tr>'+
'<tr class="detail-row hidden-detail">'+
'<td colspan="4"></td>'+
'</tr>'
);
});
$(document).ready(function() {
$('table').on('click', 'tr.status-row', function() {
var statusRow = $(this);
var detRow = statusRow.closest('tr').next('tr');
var details = this.nextElementSibling.querySelector('td');
$('.detail-view').addClass('hidden-detail');
$('.detail-view').removeClass('detail-view');
detRow.addClass('detail-view');
detRow.removeClass('hidden-detail');
if (details.innerText == '')
{
var value = statusRow.find('td:first-child').text();
postDetails(value, username, sesstoken, details);
}
});
});
}

If I understand the question correctly, I think your selector for the "hidden" tr is incorrect.
You have the click event attached to the tr, so you shouldn't have to do .closest('tr'). Just var detPane = $(statusRow[0]).next('tr'); should get you the next tr after the one that was clicked.

How to reinitialize a script in an HTML document?

I have a document that uses the jscolor.com library, for the user to be able to select and store a color. I'm also using a JQuery function to add rows to the screen, so the user can create and define a number of colors. The problem is, when the new row is added, the Javascript isn't re-initialized for the added elements.
Here is the code in question:
<script type="text/javascript">
$(document).ready(function(){
var i=1;
$("#add_row").click(function(){
$('#addr'+i).html("<div id='addr" + i + "'>" +
"<div class='col-xs-4'>" +
"<input type='text' name='config_color[" + i + "][css]' id='input-color[" + i + "][css]' class='form-control' />" +
"</div>" +
"<div class='col-xs-2'>" +
"<input type='text' name='config_color[" + i + "][value]' id='input-color[" + i + "][value]' class='form-control jscolor' />" +
"</div>" +
"<div class='col-xs-2'>" +
"<input type='text' name='config_color[" + i + "][default]' id='input-color[" + i + "][default]' class='form-control' />" +
"</div>" +
"<div class='col-xs-4'>" +
"<input type='text' name='config_color[" + i + "][notes]' id='input-color[" + i + "][notes]' class='form-control' />" +
"</div>" +
"</div>");
$('#tab_logic').append('<div id="addr'+(i+1)+'"></div>');
i++;
});
$("#delete_row").click(function(){
if(i>1){
$("#addr"+(i-1)).html('');
i--;
}
});
}).trigger('change');
</script>
I've made an simplified example of what I'm talking about on JSFiddle - you can see in the first row, if you click in the color cell, it gives you a pop up color palette.
If you add additional rows, the popup picker doesn't work.
However, all of the data stores in the database properly, so i have an instance where some elements added by Javascript work properly and others don't?
(Also full disclosure, I asked on Reddit first - this is therefore a cross-post.

In their examples, jscolor has one called "Instantiating new Color Pickers" which shows you how to do it.
You're adding the new row as a string, which I wouldn't recommend, because if you created each input separately using jQuery it would be easier to call jscolor() on only one element, but this works too.
Just add the following to your click handler:
// Get all the inputs first
var allInputs = $('.jscolor');
// From there, get the newest one
var newestInput = allInputs[allInputs.length - 1];
// And call jscolor() on it!
new jscolor(newestInput);
Here's an updated fiddle

Generally Abe Fehr answer helped me too, but i had slightly other problem. My elements already had default values from database so
new jscolor(newestInput);
initialized them but with default FFFFF
So in my case twig (html) looks like this:
<button class="jscolor {value:'{{ category.color }}'} btn btn-sm disabled color-picker" data-color="{{ category.color }}"></button>
And then I reinitialize all the colors like this:
let all_pickers = $('.color-picker');
if ($(all_pickers).length !== 0) {
$(all_pickers).each((index, element) => {
let color = $(element).attr('data-color');
new jscolor(element, {'value': color});
});
}

jQuery getJSON and get value from button

I'm download data from JSON file and display button with value:
function iterateOverPrzepisy(best) {
$('#listaPrzepisow').html('');
$.getJSON('przepisy.json', function(data) {
for (var x in przepisyDost) {
$('#listaPrzepisow').append(" <div data-role=\"collapsible\"><h2>" + przepisyDost[x].nazwa + "</h2>" +
"<ul data-role=\"listview\" data-theme=\"d\" data-divider-theme=\"d\">" +
"<li>" +
"<h3>Składniki: " + przepisyDost[x].skladniki + "</h3>" +
"<p class='ui-li-desc' style='white-space: pre-wrap; text-align: justify;'>" + przepisyDost[x].tresc + "</p>" +
"<button id='ulubioneBtn' value='" + przepisyDost[x].id + "'>Ulubione</button></li>" +
"</ul>" +
"</div>");
j++;
}
})
}
When I click to button #ulubioneBtn I would like to get value from this button. So I add done to getJSON
}).done(function(data){
$('button#ulubioneBtn').click(function (event) {
console.log("Ulubione: ");
event.preventDefault();
var id = $("button#ulubioneBtn").val();
console.log("Value: " + id);
//dodajemy do ulubionych
localStorage.setItem("ulubione"+id, id);
});
});
But it's not working. When I click on button Ulubione I always get in console log value = 0

The problem seems to be that you add multiple buttons with the same id. An id of a html element should be unique.

przepisyDost does not appear to be defined at
for (var x in przepisyDost) {
? Try
for (var x in data.przepisyDost) {
Duplicate id's are appended to document at
"<button id='ulubioneBtn' value='" + przepisyDost[x].id
+ "'>Ulubione</button></li>" +
within for loop. Try substituting class for id when appending html string to document
"<button class='ulubioneBtn' value='" + data.przepisyDost[x].id
+ "'>Ulubione</button></li>" +
You could use event delegation to attach click event to .ulubioneBtn elements, outside of .done()
$("#listaPrzepisow").on("click", ".ulubioneBtn", function() {
// do stuff
})

I have created a dummy JSON and executed the same JS with a single change.
In onclick handler instead of getting button I am using $(event.target).
And it is working fine.
Please find the fiddle https://jsfiddle.net/85sctcn9/
$('button#ulubioneBtn').click(function (event) {
console.log("Ulubione: ");
event.preventDefault();
var id = $(event.target).val();
console.log("Value: " + id);
//dodajemy do ulubionych
localStorage.setItem("ulubione"+id, id);
});
Seems like first object doesn't have any id value.
Please check JSON response returned from server.
Hope this helps you in solving.

jQuery selector unable to find table row class

Given an array of strings returned from an sql query, I am appending the data as rows into my html table via javascript:
loadUsers: function()
{ .
.
.
function displayUsersOnTable(response)
{
for(var i = 0; i < response.results.length; i++)
{
var contact = response.results[i];
var $newRow = $('<tr class="user-row">' +
'<td>' + contact.full_name + '</td>' +
'<td>' + contact.email + '</td>' +
'</tr>')
.data('user', contact);
$userTableBody.append($newRow);
}
}
}
Inside a different function that is called after loadUsers is called, I have this:
$('.user-row').click( function() {
window.alert("CLICKED");
});
When I run my site it won't register the click event. If I select the classes from my table row or table header it runs fine. I suspect the problem involves the fact that the table rows are dynamically generated. When I inspect element everything is in place. What am I missing?

try:
$(document).on('click', '.user-row', function() {
window.alert("CLICKED");
});

How to fetch the id of dynamically generated textboxes?

How is it possible to get the id of the dynamically generated textboxes using jquery?. I need to fire the TextChanged event for the corresponging textbox. There is no method reference for the textboxes in the code behind.How can i refer to any method in the codebehind on firing the event. Somebody please help. I dont know jquery much. The entire script im using is as as follows:
<script type="text/javascript">
$(init);
function init()
{
$('#test').droppable(// Div Control
{
drop: handleDropEvent
});
$('a').each(function(idx, item) {
$(item).draggable({ cursor: 'move', helper: 'clone' })
});
}
$(function() {
$("#draggable").draggable(); //Nothing to do with this div
});
function handleDropEvent(event, ui)
{
var draggable = ui.draggable;
document.getElementById('test').innerHTML += addColumn(draggable.attr('text')) + '<br>';
}
function addColumn(column)
{
var iHtml;
// This code will generate a checkbox and a textbox. I need to fire the event of thus generated textboxes.
iHtml = '<div id="dv' + column + '" width="100px;" height="20px;" padding: "0.5em;"> ' + '<span title="ToolTipText">' + '<input type="checkbox" id="cb' + column + '" value="' + column + '" /> <label for="cb' + column + '">' + column + '</label></span><input type="text" runat="server" id="aln' + column + '"> </div>';
return iHtml;
}
</script>

There's two ways: keep the generated element, or generate an ID when you generate your new element.
a) keep the generated element
This requires that you don't use innerHTML, but create the element (with document.createElement, or with jQuery's $), and then you can use the element directly (no need to call it by ID any more). For instance, with jQuery:
var container = $('#container');
var myDiv = $('<div id="myDiv"/>');
var myCheck = $('<input type="checkbox"/>');
myDiv.append(myCheck);
container.append(myDiv);
b) generate the ID
container.innerHTML = '<div id="myDiv"><input type="checkbox" id="myCheck"/></div>';
// and after this you can get them by ID:
var myCheck = $('#myCheck');

I would just add a class to the textbox in your iHtml then use .live() event
replace your iHtml with this
iHtml = '<div id="dv' + column + '" width="100px;" height="20px;" padding: "0.5em;"> ' + '<span title="ToolTipText">' + '<input type="checkbox" id="cb' + column + '" value="' + column + '" /> <label for="cb' + column + '">' + column + '</label></span><input class="myclass" type="text" runat="server" id="aln' + column + '"> </div>';
then add the live event
$('.myclass').live('change', function() {
alert(' Live handler called.');
});
