Append search results to respective parent div?

I'm implementing autocomplete using webSocket. When I type in the input field which has the classname item-search-results, a bunch of result will show up search results screenshot. My problem is the result will is only attach to the very first item-search-results input field.
But I need the results show up under the right item-search-results input field.
For example, I type on the 4th item-search-results input field, but the results are attach to the first one results are attach to the first row screenshot
Here is my webSocket js, I use jQuery:
$(function () {
let webSocket = new WebSocket("ws://localhost:8000/autocomplete");
webSocket.onopen = (msgEvent) => {
console.log('connected to WebSocket!');
};
webSocket.onmessage = (msgEvent) => {
/* results shows {"results":{"results":[{..}]}}.
results.results shows {results:[{..}]}
results.results.results shows [{...}], which is an array */
let results = JSON.parse(msgEvent.data),
resultsArr = results.results.results;
console.log(resultsArr);
$.each(resultsArr, (index, value) => {
$('<div>' + value['name'] + '</div>').attr('id', 'item-search-results-' + index).appendTo($('.item-search-results'));
});
};
webSocket.onclose = (msgEvent) => {
console.log('disconnected');
};
webSocket.onerror = (msgEvent) => {
console.log('there\'s an error');
};
/**
* Request to display data
*/
$('.add-items-table').on('input', '.item-input', (e) => {
let value = e.target.value;
webSocket.send(value);
console.log(value);
})
})

Websockets are irrelevant here, and I don't understand why you are doing an append inside loop. When trying to do something like this, you need to use the $(this) selector which will be the element you actually click.
At the top of your script create a global variable or namespace.
var Item = {};
/* In this chunk of code, create an object which you can use as a reference */
$('.add-items-table').on('input', '.item-input', (e) => {
/* this will be the correct .item-search-results div */
var Item.list = $(this).siblings('.item-search-results');
let value = e.target.value;
webSocket.send(value);
console.log(value);
})
Finally, append to the correct <div>.
.appendTo(Item.list);

Not sure about Websocket But here is how you will approach.Get last Row of table and append data after that particular row.
var placeHolder=` <tr>
<td style="width: 16.66%">
<input type="text" name="quanty" value="">
</td>
<td class="item-search-container">
<input class="item-input" id="item-input-0" type="search" name="item" value="">
<div class="item-search-results"></div>
</td>
<td>
<input type="text" name="quanty" value="">
</td>
</tr>`;
function addItem(){
let totalElem=document.getElementsByClassName('tr').length;
let lastElem=document.getElementsByClassName('tr')[totalElem-1];
$.get( "https://jsonplaceholder.typicode.com/posts/1", function( data ) {
$.each(data, function(i, item) {
$(lastElem).after(placeHolder);
});
});
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<section class="item-form">
<table class="add-items-table table table-hover ">
<thead>
<tr>
<th>Quanty</th>
<th>Item</th>
<th>Comment</th>
<th>Remove</th>
</tr>
</thead>
<tbody class="item-row">
<tr class="tr">
<td style="width: 16.66%">
<input type="text" name="quanty" value="">
</td>
<td class="item-search-container">
<input class="item-input" id="item-input-0" type="search" name="item" value="">
<div class="item-search-results"></div>
</td>
<td>
<input type="text" name="quanty" value="">
</td>
<td>
<button class="remove-item-button btn-block btn-outline-danger" type="reset" name="remove">
<i class="fa fa-trash-o" aria-hidden="true"></i>
</button>
</td>
</tr>
</tbody>
</table>
<button class="add-item" onClick="addItem()">Add Another Item</button>
</section>

The problem here is that you are appending it to $('.item-search-results') that is a class and is returned as an array. When you run .appendTo($('.item-search-results')) it will append to the first item of the array.
You should use a more specific Id for each roll and append by Id.
I think #manikant 's idea of creating a template is great, but I would introduce a variable that you can change for each new row you create and give a different Id to each .item-search-results div. But you would have to send this to the websocket and receive it back to call the right Id to append.

Find the sum of a column in html table using Jquery or JS

I have a html table created using jQuery:
success: function(data, textStatus, errorThrown) {
var rows ="";
function formatItem(data) {
return '<td>'+data.name + '</td> <td> ' + data.price + ' </td><td>' + "<input></input>" +'</td>';
}
$.each(data, function (key, item) {
$('<tr>', { html: formatItem(item) }).appendTo($("#foodnames"));
});
}
This is what the interface looks like:
The table is working fine with all the data showing.
The problem is finding the sum of the third column. Where I can enter a number and display it using an id.
Is there anyway to do it?

What you want to do is to use jQuery to select the table, and all of the third td's for each row, then sum it. The basic pseudocode is:
Clear the output box.
ForEach TR
Select the third TD
Add that value to the output box.
End ForEach
To do that in jQuery, you just need to know how to select the right values. Assigning relevant class/id names is helpful.
I put together a basic example that you can run. It will tabulate the total of the third column dynamically, as you change the value. I hard coded the price column, but you could easily put some other values or input there.
I put it in an onChange event handler, but if you are loading the data from a server or something, you could do document onLoad or whenever your ajax is complete.
//trigger an event when the input receives a change
$("#exampleTableContainer table td input").off("change").on("change", function(ele) {
//clear the out put box
$("#totalOut").val("0");
//for the table container, select all tr's within the table's tbody.
//Excluding tbody will also select the thead.
$("#exampleTableContainer table tbody tr").each(function(index, rowElement) {
//tablulate the cost of the current row
var rowCost = parseInt($(rowElement).find(".cost").text()) * parseInt($(rowElement).find(".amount input").val());
//if the rowCost is a valid number, add it to whatever is in the output box
if (rowCost) $("#totalOut").val(parseInt($("#totalOut").val()) + rowCost)
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="exampleTableContainer">
<table>
<thead>
<tr>
<th class="item">Item</th>
<th class="cost">Cost</th>
<th class="amount">Amount</th>
</tr>
</thead>
<tbody>
<tr>
<td class="item">Item 1</td>
<td class="cost">123</td>
<td class="amount">
<input type="number">
</td>
</tr>
<tr>
<td class="item">Item 2</td>
<td class="cost">1</td>
<td class="amount">
<input type="number">
</td>
</tr>
<tr>
<td class="item">Item 3</td>
<td class="cost">2</td>
<td class="amount">
<input type="number">
</td>
</tr>
<tr>
<td class="item">Item 4</td>
<td class="cost">4</td>
<td class="amount">
<input type="number">
</td>
</tr>
</tbody>
</table>
<br>
<div>
Total:
<input id="totalOut" readonly value="0">
</div>
</div>

I'm not sure if you plan to use this in a production environment or not, so maybe this is overkill for what you're trying to accomplish, but I would recommend using an underlying data model bound to the table. Then you can get your sum from your data:
const data = [
{food: "Veggie burger", price: 200, qty:1},
// ...Add as many food items as you like
]
You would be able to use the data to build your table:
// Get a reference to the table and create a document fragment
const table = document.getElementById("table-body");
const body = document.createDocumentFragment();
// Fill the fragment with your data:
data.map((value, key) => {
// Row-building logic goes here
// this probably isn't what you actually do here:
const row = document.createElement("tr");
row.className = key;
for (let x in value) {
const dataCell = document.createElement("td");
dataCell.className = x;
dataCell.innerHTML = value[x];
row.appendChild(dataCell);
}
body.appendChild(row);
});
table.innerHTML = "";
table.appendChild(body);
Then you can calculate your sum based on the data, not the UI:
const subTotal = data
.map((value) => value.price * value.qty)
.reduce((a, b) => a + b);
document.getElementById("total").textContent = subTotal;
You would set an event listener on the table(parent node) and use event.target to find the row and column (.qty in this case) and update the corresponding field (qty) in the data object when the input is changed.
$("#my-table").on("input", (e) => {
// You would probably be better off using a custom attribute than a class since there can be multiple classes, but we'll use class to keep it simple:
const column = $(e.target).parent("td").attr("class");
const row = $(e.target).parent("td").parent('tr').attr("class");
data[row][column] = e.target.value;
console.log(data);
});
This pattern also makes it easy to send the updated data back to the REST API to update your database later.

I know you said you're using jQuery, but ES6 is much nicer in my opinion.

Try this:
$(document).ready(function(){
var total = 0;
$("#submit").click(function(){
$(".user_input").each(function(){
var value = parseInt($(this).val());
total += value;
});
$("#output").text(total);
});
});
HTML
<input type="text" name="value1" class="user_input"/>
<input type="text" name="value2" class="user_input"/>
<input type="text" name="value3" class="user_input"/>
<button name="submit" id="submit" value="calculate">
Calculate
</button>
<div>
<span>Total:</span><div id="output">
</div>

AngularJs: uncheck checkbox after item is removed

after spending a lot of time on this simple issue and having made a lot of research, I was wondering if someone could give me some help.
I have data which is generated inside of a table like so:
<tbody>
<tr class="odd gradeX" ng-repeat="user in ctrl.datas | orderBy:ctrl.sortType:ctrl.sortTypeReverse">
<td>
<input type="checkbox" class="checkboxes" value="{{user.id}}" ng-click="ctrl.addItem(user)"/>
</td>
<td>
{{user.given_name}}
</td>
<td>
{{user.family_name}}
</td>
<td>
{{user.email}}
</td>
<td class="center" ng-bind-html="ctrl.convertToDate(user.created_at) | date: 'dd-MMMM-yyyy hh:mm'"></td>
<td>
<span class="btn blue-hoki"> Details </span>
</td>
</tr>
</tbody>
Above is a container where I get the items selected via a checkbox, add the in an array and give the user the ability to delete the selected item:
<tr ng-repeat="user in ctrl.checkedObject track by $index" ng-show="user.id">
<td>{{user.family_name}}</td>
<td>{{user.given_name}}</td>
<td>
<button class="btn blue" ng-click="ctrl.removeItem($index)">Unselect</button>
</td>
</tr>
In my controller, here are the two functions used to do so:
this.checkedObject = [];
//Add selected user
this.addItem = function (user) {
self.checkedObject.push(user);
};
this.removeItem = function(obj){
delete self.checkedObject[obj];
};
What i'd like to achieve is to uncheck the corresponding checkbox if a user changes his selection.
The thing is, I have no idea how to target the corresponding checkbox. Does anyone have a clue?
Thanks in advance

Try ng-checked like:
<input type="checkbox" ng-checked="user !== null" class="checkboxes" value="{{user.id}}" ng-click="ctrl.addItem(user)"/>
And set the item (user) to null on button click (inside removeItem() ) or a other variable.

I set up a simple plunker to show one approach, which would be to assign a selected property to each user when his/her checkbox is checked, and set an ng-checked attribute on the checkbox corresponding to user.selected (so will be unchecked when false).
Using this approach you won't need to push and delete from the array of checkedUsers, you can just filter all the users by whether they are selected or not.
function getSelected() {
ctrl.checkedObject = _.filter(ctrl.datas, {selected: true});
}
ctrl.selectUser = function (user) {
user.selected = true;
getSelected();
};
ctrl.removeUser = function(user){
user.selected = false;
getSelected();
};

How to find next elements using jquery?

In my given example, i have two text boxes. when value in first text box changed i want to find the immediate next text box (note : without id) and change its value.
The example given contains only single text box group. actually it can be more than one text boxes. (group of from & to text boxes of Financial Data)
so, when value in from text box (txtFinancialYearFrom) changed, i want to find the to text box (txtFinancialYearTo) and change its value as well.
JsFiddle Link - Example
Thanks in advance for the help!!
<table class="fotm-table">
<tr>
<td class="text-right" width="120">
<span id="ContentPlaceHolder1_lblFinancialYear">Financial Data :</span>
</td>
<td>
<span>
<input type="text" id="txtFinancialYearFrom"
name="ctl00$ContentPlaceHolder1$txtFinancialYearFrom">
</span>
</td>
<td width="20" align="center">
<span style="align-content: center">to</span>
</td>
<td>
<span>
<input type="text" id="txtFinancialYearTo"
name="ctl00$ContentPlaceHolder1$txtFinancialYearTo">
</span>
</td>
</tr>
</table>

Using the given information, since you are going to have more blocks (that should be rows on your table), this solution should work:
var rows = $('.fotm-table tr');
$(rows).each(function(){
$('input:first', $(this)).on('change', function(){
var fromValue = $(this).val();
var row = $(this).closest('tr');
$('td:last input', row).val(parseInt(fromValue) + 1);
});
});
The code gets all the rows from your table and for each one of them, it will add a listener that when you change the first textbox (input), it will change the value of the next textbox (here it's adding 1 to it).

If I've understood correctly, you need something like this:
/* Loop through all table rows */
$('tr','table.fotm-table').each(function() {
var tr = this;
/* Cache all inputs a jquery object - you may want to specify which type of input you are targeting i.e. $('input[type="text"]') */
var inputs = $('input',tr);
/* Cache the slave (second in the example) input in a jquery object - you can do the same for multiple inputs, simply by modifying the eq() index parameter
*/
var slaveInput = inputs.eq(1);
/* Listen for changes on the master input */
var masterInput = inputs.eq(0).on('change',function() {
/* Do smt on the slave input - fill it with the next year in the example */
var year = $(this).val();
var followingYear = parseInt(year,10)+1
slaveInput.val(followingYear);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="fotm-table">
<tr>
<td class="text-right" width="120">
<span id="ContentPlaceHolder1_lblFinancialYear">Financial Year :</span>
</td>
<td>
<span>
<input type="text" id="txtFinancialYearFrom"
name="ctl00$ContentPlaceHolder1$txtFinancialYearFrom">
</span>
</td>
<td width="20" align="center">
<span style="align-content: center">to</span>
</td>
<td>
<span>
<input type="text" id="txtFinancialYearTo"
name="ctl00$ContentPlaceHolder1$txtFinancialYearTo">
</span>
</td>
</tr>
</table>
Here's an updated fork of the jsFiddle you provided:
https://jsfiddle.net/jkdaza/thonfzwu/5/

You can use this tricky solution from link:
$('#txtFinancialYearFrom').change(function(el) {
$(':input:eq(' + ($(':input').index(this) + 1) + ')').val('test');
});

Iterating through table and get the value of a button in each tablerow jQuery

I have buttons in a table which are created dynamically. I want to iterate through a table, get the tablerows which contain a checked checkbox and get the value of a button inside the tablerow. I want to push the values in an array after. The buttons don't have a unique ID so I cannot get their values by id.
I tried to get the values through giving the buttons a class and itering works fine but the array is filled with empty entries.
$("#bt_multiple_deletion").off().on("click", function () {
var files = [];
var rows = $(".select").find("input[type=checkbox]:checked");
rows.each(function () {
files.push($(this).find(".filefolder-button").text());
});
})
I really don't know what Im doing wrong. I tried to get the values with .text(), .val() etc.
My table row looks like this:
<tr class="select">
<td>
<span class="countEntries"><input id="lv_fifo_ctrl7_cb_delete_file" type="checkbox" name="lv_fifo$ctrl7$cb_delete_file" /></span>
</td>
<td>
<img src="images/icons/013_document_02_rgb.png" alt="document" />
</td>
<td class="name">//the button i want to get the value from
<input type="submit" name="lv_fifo$ctrl7$bt_file" value="013_document_png.zip" id="lv_fifo_ctrl7_bt_file" class="filefolder-button download file del" style="vertical-align: central" />
</td>
<td>
<span id="lv_fifo_ctrl7_lb_length">33.14 KB</span>
</td>
<td>
<span id="lv_fifo_ctrl7_lb_CreationTime">21.10.2014 07:34:46</span>
</td>
<td></td>
<td>
<input type="submit" name="lv_fifo$ctrl7$bt_del_file" value="delete" id="lv_fifo_ctrl7_bt_del_file" class="delete-button delete-file" />
</td>
</tr>

The problem is rows is the input elements not the tr elements so in the loop you need to find the tr which contains the input then find the target element inside it
$("#bt_multiple_deletion").off().on("click", function () {
var checked = $(".select").find("input[type=checkbox]:checked");
var files = checked.map(function () {
return $(this).closest('tr').find(".filefolder-button").val();
}).get();
})
Another option is
$("#bt_multiple_deletion").off().on("click", function () {
var rows = $(".select").find("tr").has('input[type=checkbox]:checked');
//var rows = $(".select").find('input[type=checkbox]:checked').closest('tr');
var files = rows.map(function () {
return $(this).find(".filefolder-button").val();
}).get();
})

#Timo Jokinen Do you need this
$("#bt_multiple_deletion").on("click", function () {
var files = [];
var rows = $(".select").find("input[type=checkbox]:checked");
rows.each(function () {
files.push($(this).parents("tr").find("td.filefolder-button").text());
});
console.log(files);
})
<table class="select">
<tr>
<td class="filefolder-button">test1</td>
<td><input type="checkbox" /></td>
</tr>
<tr>
<td class="filefolder-button">test2</td>
<td><input type="checkbox" /></td>
</tr>
<tr>
<td class="filefolder-button">test3</td>
<td><input type="checkbox" /></td>
</tr>
</table>
<button id="bt_multiple_deletion">delete</button>
