Get the ID in row that has radio button checked [duplicate]

This question already has answers here:
Getting values of elements in same row when button is clicked, one button per row
(2 answers)
Closed last year.
I have this function which creates a table in a modal popup and the table gets populated from data in an array passed in from an ajax call. Now on the click of a button in the modal popup I need to get the value of item.TimedPathwayID that has its radio button checked and add it to a hidden field.
function PopulateTimedPathwaysTable(tblData) {
var tbody = $('#tblTimedPathways tbody');
$.map(tblData.d, function (item) {
tr = $('<tr></tr>');
tr.append('<td class="pathwayID">' + item.TimedPathwayID + '</td>');
tr.append('<td>' + item.TimedPathwayName + '</td>');
tr.append('<td><input type="radio" class="radioSelection" name="timedPathwaySelection"" />');
tbody.append(tr);
});
$('input[name=timedPathwaySelection]:first').attr('checked', true);}
}
I've been fiddling with this kind of thing but with no joy and the radio button in the first row is checked by default so this can't really be tied to a click event if a user just accepts the default without clicking. So how can I do it please?
$('body').on('click', '.radioSelection', function () {
var $tbl = $('#tblTimedPathways tbody');
var $dataRow = $tbl.closest('tr');
var id = $dataRow.find('td').eq(0).html();
});

.closest goes up the html tree, so tbody.closest(tr) is unlikely to be what you want.
you need to then go back down to the cell that contains the data you want.
let $this = $(this); //this is the radio button
let id = $this.closest("tr").find("td.pathwayID").text();
I would also echo that I would generally add the id as an attribute to the row to remove the necessity of the find later.
//sample data
let data = {
d: [{
TimedPathwayID: 1,
TimedPathwayName: "test"
},
{
TimedPathwayID: 2,
TimedPathwayName: "test"
},
{
TimedPathwayID: 3,
TimedPathwayName: "test"
}
]
};
function PopulateTimedPathwaysTable(tblData) {
var tbody = $('#tblTimedPathways tbody');
$.map(tblData.d, function(item) {
tr = $('<tr></tr>');
tr.append('<td class="pathwayID">' + item.TimedPathwayID + '</td>');
tr.append('<td>' + item.TimedPathwayName + '</td>');
tr.append('<td><input type="radio" class="radioSelection" name="timedPathwaySelection"" />');
tbody.append(tr);
});
$('input[name=timedPathwaySelection]:first').attr('checked', true);
}
//populate it
PopulateTimedPathwaysTable(data);
$('body').on('click', '.radioSelection', function () {
let $this = $(this); //this is the radio button
//console.log($this);
let id = $this.closest("tr").find("td.pathwayID").text();
console.log(id);
});

Jquery how to pass value id from one event handler to another

I have an add-row button. On its click I am adding a row into my datatable.
$('.add-row').on('click', function() {
id = 0;
name = $('#name').val();
email = $('#email').val();
cno = $('#cno').val();
bdy = $('#bday').val();
t.row.add([
name,
email,
cno,
bdy,
'<button class ="btn btn-danger del">Delete</button>' + '' + '<button class="btn btn-warning upd" data-id="'+$('#example').DataTable().rows().count()+'">Edit</button>'
]).draw(false);
$("#name").val('');
$("#email").val('');
$("#cno").val('');
$("#bday").val('');
});
In the above code, I am using data-id and adding row id to it. On my edit button click I am getting the data-id value.
$("body").on("click", ".upd", function(e) {
const id = $(this).attr("data-id");
console.log(id);
// Prevent event propagation
e.stopPropagation();
var $row = $(this).closest('tr');
var data = t.row($row).data();
//alert('Edit ' + data[0]);
name = data[0];
email = data[1];
cno = data[2];
bdy = data[3];
console.log(name);
console.log(email);
console.log(cno);
console.log(bdy);
$("#name1").val(name);
$("#email1").val(email);
$("#cno1").val(cno);
$("#dob1").val(bdy);
$("#myModal").modal('show');
});
The above code takes input data from modal. In my modal I have a save button having id btnsubmit. Now on this button click, I want to pass my data-id.
$("#btnsubmit").on('click',function () {//in this event i want to pass the `data-id`
var new_name = $("#name1").val();
var new_email = $("#email1").val();
var new_cno = $("#cno1").val();
var new_dob = $("#dob1").val();
$("#myModal").modal("hide");
});
How can I pass the value of data-id in it?
Any help would be highly appreciated.

you could stock your data in html modal like this:
$("#myModal").data('id', id);
and use:
var id = $("#myModal").data('id');

javascript save state of check boxes

I am having an issue where the current state of the checkbox is not being saved. I am new to this and any help would be appreciated. Here's the jQuery code that is partially working.
var userCityList = [];
$("#checkboxes").unbind('change').bind('change', function (event) {
var stateVal = $(':selected', $('#ResidentialLocationStateList')).val();
var cityID = $(event.target)[0].id;//stores city id
var cityVal = $(event.target)[0].value;//stores city value
if ($('#' + cityID).is(':checked')) {
if (userCityList.length < 5) {
userCityList.push(cityID);
}
else {
$('#' + cityID).prop('checked', false);
alert("5 cities have been selected");
return;
}
}//end if
if (!($("#" + cityID).is(':checked'))) {
userCityList.pop();
}
//console.log(userCityList);
});
LOGIC
When the user selects a state, a set of cities in checkboxes appear. When a user clicks a checkbox, that particular city is stored in the userCityList array. When the user clicks it again, it deletes it from the array. However, if the user changes the state, those cities are no longer checked, which does not allow one to delete it from the array, if needed.
Any suggestions?
HTML code
<div class="panel-body">
<p>Select upto 5 state/city combinations</p>
<div class="col-xs-3 no-pad-left less-width">
#*<p>Select upto 5 state/city combinations</p>*#
<select id="ResidentialLocationStateList" name="ResidentialLocationStateList" multiple></select>
</div>
<div class="col-xs-3" id="checkboxes">
</div>
</div>
UPDATE Here's the image that goes with this issue.
So when a few cities are selected and the user decides to change the state from the select element, those cities that were selected prior need to be saved.
UPDATE
Here's the AJAX code...
$("#ResidentialLocationStateList").change(function () {
url = "/ResidentialBuilding/getCityList?state=";
state = $("#ResidentialLocationStateList").val();
url = url + state;
//console.log(url);
$("#checkboxes").empty();
$.getJSON(url, function (data) {
//console.log(data);
$.each(data, function (index, value) {
//console.log(value.city);
id = value.city;
id = id.replace(/\s+/g, '');
valCity = value.city;
valCity = valCity.replace(/\s+/g, '');
$("#checkboxes").append('<input value="' + valCity + '"' + 'type=' + "'checkbox'" + 'id=' + id + '>' + value.city + '</input><br>');
});
});
});

If you're using a modern version of jQuery I would recommend using .off and .on and to use .off if you really have to.
lso the .pop() array method removes the last element but the element just clicked may not always be the one that was added last. And since, the check boxes are added dynamically, the following bind could be made at the very beginning of DOM ready and not necessarily in any event handler. Rather than give your checkboxes the same ID which leads to invalid HTML, use a class selector, .checkboxes.
Therefore, I would suggest the following code
var userCityList = [];
$(document).on("change", ".checkboxes", function() {
var stateVal = $('#ResidentialLocationStateList').val();
var cityID = this.id;//stores city id
var cityVal = this.value;//stores city value
var finalDiv = $('#final');
var tempDiv = $('#othertempdiv');
if( this.checked ) {
if( userCityList.length < 5 ) {
userCityList.push( cityID );
finalDiv.append( this );
} else {
$(this).prop('checked', false);
alert('5 cities have been selected');
}
} else {
var index = $.inArray( cityID, userCityList );
if( index > -1 ) {
userCityList.splice( index, 1 );
tempDiv.append( this );
}
}
});
Since you're -- per comments below -- replacing the selected cities each time you select a new state, you would have to have a second div which would hold all the selected cities. Un-checking any of the cities in this final div would move it back; if another state is selected, such a city would be lost.
<div id="final"></div>

Use a multidimensional array to store both state and city IDs, like userCityList [ stateVal ]:
var userCityList = [];
$("#checkboxes").unbind('change').bind('change', function (event) {
var stateVal = $(':selected', $('#ResidentialLocationStateList')).val();
var cityID = $(event.target)[0].id;//stores city id
var cityVal = $(event.target)[0].value;//stores city value
if ($('#' + cityID).is(':checked')) {
if (userCityList.length < 5) {
if(!userCityList[stateVal])userCityList[stateVal] = [];
userCityList[stateVal].push(cityID);
}
else {
$('#' + cityID).prop('checked', false);
alert("5 cities have been selected");
return;
}
}//end if
if (!($("#" + cityID).is(':checked'))) {
if(userCityList[stateVal]){
//Edited, now it can remove the city by its position (index)
var position = $.inArray(cityID, userCityList[stateVal]);
userCityList[stateVal].slice(position, 1);
}
}
});
So when you need to retrieve the checked cities for an state you can do just:
for(var i =0; i < userCityList[stateVal].length; i++){
console.log(userCityList[stateVal][i]);
}
UPDATE
The hard work is done. Now, in your ajax code, when you load a new set of checkboxes, you have to check if the checkbox was previously checked:
$("#ResidentialLocationStateList").change(function () {
url = "/ResidentialBuilding/getCityList?state=";
state = $("#ResidentialLocationStateList").val();
url = url + state;
//console.log(url);
$("#checkboxes").empty();
$.getJSON(url, function (data) {
//console.log(data);
$.each(data, function (index, value) {
//console.log(value.city);
id = value.city;
id = id.replace(/\s+/g, '');
valCity = value.city;
valCity = valCity.replace(/\s+/g, '');
$("#checkboxes").append('<input value="' + valCity + '"' + 'type=' + "'checkbox'" + 'id=' + id + '>' + value.city + '</input><br>');
//Let's check if this checkbox was previously checked
if($.inArray(id, userCityList[state])){
//if yes, let's check it again
$('#'+id).prop('checked', true);
}
});
});
});
Keep in mind that the userCityList variable must be global to store these values and you will loose your checkboxes memories if you refresh the page, of course.

Remove button in table row

I am working on a shopping cart application. I have used jQuery to fetch the items and display it in table format. Each item table contains a remove button to remove it from the cart. I have used the click function on the table to remove the item. But if I click on the qty field also the table is removed because its inside the table. I want the table to be removed when I click the remove button inside the table.
$(document).ready(function(){
$(".add_cart").click(function(){
var id = this.id;
$(this).prop("disabled",true);
$.get("cart.php",{
"id":id
},function(data){
$("#sam").append("<table id='"+id+"' class='tables'><tr><td>"+data+"</td><td><input class='remove' id='"+id+"' type='button' value='Remove'></td></tr></table><br>");
$(".remove").click(function(){
$(table.tables).remove();
$("#"+id).prop("disabled",false);
});
});
});
});

use this:
$("table.tables").remove();

Try
$(document).ready(function () {
$(".add_cart").click(function () {
var id = this.id;
$(this).prop("disabled", true);
$.get("cart.php", {
"id": id
}, function (data) {
$("#sam").append("<table id='" + id + "' class='tables'><tr><td>" + data + "</td><td><input class='remove' type='button' value='Remove'></td></tr></table><br>");
});
});
//use event delegation
$("#sam").on('click', '.remove', function () {
//get the table which contains the button
var $tbl = $(this).closest('tr').remove();
//get the id of the table instead of the id variable
$("#" + $tbl.attr('id')).prop("disabled", false);
});
});
Note that the Id of an element must be unique, you have a table and a button with the same id... remove the id from the button

Javascript/jquery write each text value from :selected option to separate input

I'm retrieving some data from MySQL and write it in certain select tags, then i retrieve every selected option value and display it in a DIV, here is the javascript:
function main() {
$("select").change(function () {
var str = "";
$("select option:selected").each(function () {
str += $(this).text() + " ";
});
$("div#one").text(str);
})
.trigger('change');
}
So, i want each retrieved value to be written in separate input:
First value: <input type="text" id="test" />
Second value: <input type="text" id="test2" />
Third value: <input type="text" id="test3" />
How can i do that? Many thanks!

Simple select always have a selected value, so you can try something like this:
$(function() {
$("select").change(function() {
var str = "";
$("select").each(function() {
str += $(this).val()+"<br/>";
});
$("div#one").html(str);
});
});
You can see in action here: http://jsfiddle.net/vJdUt/

For adding the selected options in a "div" tag:
//empty div at start using .empty()
$("select").change(function () {
//get the selected option's text and store it in map
var map = $("select :selected").map(function () {
var txt = $(this).text();
//do not add the value to map[] if the chosen value begins with "Select"
return txt.indexOf("Select") === -1 ? txt + " , " : "";
}).get();
//add it to div
$("#one").html(map);
});
For adding the selected options in an "input" tag:
//empty textboxes at start using .val("")
$("select").change(function () {
var text = $(":selected", this).text() //this.value;
//get the index of the select box chosen
var index = $(this).index();
//get the correct text box corresponding to chosen select
var $input = $("input[type=text]").eq(index);
//set the value for the input
$input.val(function () {
//do not add the value to text box if the chosen value begins with "Select"
return text.indexOf("Select") === -1 ? text : "";
});
});
