Getting selected radio button in JavaScript

I've tried lot's of solutions here before actually make this question but none of them has worked for me.
I've tried to use onclick handler, tried to get by input name, tried getElementId, tried elementClassName also i tried to loop them var i = 0, length = radios.length; i < length; i++ none has worked for me!
Logic
My radio buttons will append to view based on ajax action
I select any of this radio buttons
And i want get values of this selected radio button
Code
This is how my radios append I made it short to be clean and easy to read
success:function(data) {
$('.shipoptions').empty();
$('.shipoptionstitle').empty();
$('.shipoptionstitle').append('<h6>Select your preferred method</h6>');
$.each(data.data, function(key, value) {
$.each(value.costs, function(key2, value2) {
$.each(value2.cost, function(key3, value3) {
// number format
var number = value3['value'];
var nf = new Intl.NumberFormat('en-US', {
maximumFractionDigits:0,
minimumFractionDigits:0
});
var formattedNumber = nf.format(number);
// number format
$('.shipoptions').append('<ul class="list-form-inline"><li><label class="radio"><input type="radio" name="postchoose" data-code="'+value['code']+'" data-service="'+value2['service']+'" value="'+ value3['value'] +'"><span class="outer"><span class="inner"></span></span>'+ value['code'] + ' - ' + value2['service'] + ' - Rp ' + nf.format(number) + ' - ' + value3['etd'] +'</label></li></ul>');
});
});
});
} //success function ends here
Now I want to get selected radio button values of data-code ,
data-service and value
For the temporary please just help me to get those values in console, later I'll fix the printing part myself.
Any idea?

<input type="radio" name="postchoose" data-code="'DC11'" data-service="'DS22'" value="'V33">
var dataCode = $('input[name="postchoose"]:checked').data('code');
var dataService = $('input[name="postchoose"]:checked').data('service');
var selectedVal= $("input:radio[name=postchoose]:checked").val();

SOLVED
$(function() {
$(".shipoptions").on('change', function(){
var radioValue = $("input[name='postchoose']:checked");
if(radioValue){
var val = radioValue.val();
var code = radioValue.data('code');
var service = radioValue.data('service');
alert("Your are a - " + code + "- " +service+ "- " +val);
}
});
});
I needed to get a higher class of my radio buttons .shipoptions

Try this jQuery Method.
$("input[type='radio']").click(function() {
var radioValue = $("input[name='postchoose']:checked").val();
var dataCode = $("input[name='postchoose']:checked").attr('data-code');
var dataService = $("input[name='gender']:checked").attr('data-service');
console.log(dataCode);
console.log(dataService);
console.log(radioValue);
});

How do I change this Contact Form's Javascript so that IF a key is something else, perform different action?

I have a Contact Form that utilizes Google Scripts. It successfully sends the email and formats it decently to my inbox, but there are 2 problems:
-I need it so that IF var key is equal to 'Action', then do not display it in the email it sends. Because right now, "Action send_message" is getting included in the email and I don't like that.
For this, I have unsuccessfully tried things like:
for (var idx in order) {
var key = order[idx];
//Skip this entry into the email output if it is the Action
if( key === 'Action') {
continue
}
It seems to not react to this code at all.
-I also need it so that if a city is selected, e.g. Alachua, that the email says 'Alachua' instead of 'Florida_Alachua'. But I can't add a NAME to an option since apparently options don't have that property. I also can't do the quick fix of changing the VALUE of the <option> to resolve this step, because of other code I have that conflicts with this route.

finally, this is the extra code that would break if I simply tried changing the value of option to, e.g., 'Alachua' instead of 'Flordia_Alachua'. https://jsfiddle.net/hmatt843/504dgmqy/19/
Thanks for any and all help.

Try console.log(key) before if( key === 'Action'). I think you'll find that key never equals 'Action', exactly. Looks like you'll need if( key === 'action'), instead.
If you wish to remove part of string value, try the replace method: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace
It also looks like you're trying to work with elements[k].name when you mean to be working with elements[k].value.
I believe your code should look something like...
function(k) {
if(elements[k].value !== undefined) {
return elements[k].value.replace('Florida_', '');
// special case for Edge's html collection
} else if(elements[k].length > 0){
return elements[k].item(0).value.replace('Florida_', '');
}
}
... or something to that effect.
In the future, you may want to make it easier for folks trying to help you by posting only the portions of code your having trouble with, and breaking your questions into different posts. A lot to sift through up there.
Hope this helped.

The split() method splits a String object into an array of strings by separating the string into substrings, using a specified separator string to determine where to make each split.
Var splitValue = elements[k].item(0).value.split("");
splitValue[1] will give you a string of characters after the delimeter () in this case.

Js on change dropdown

I have a form that has a hidden text input that gets the user id called user_number_id and depending on the value the dropdown called departamento_drop gets an options filtered to retorno1. The problem is that when I open this form to edit something inside it, the selected option of this dropdown changes automatically and changes the real selected value. How can I keep the selected value selected and make sure the filter can understand that and have to respect it?
$("#user_number_id").val(function(){
var selecionado = $(this).val();
jQuery.get("<?php echo base_url().'departamentos/filter_departamento/'; ?>"+selecionado,
function(retorno1){
var ret1 = '<option value="0">------ N/A ------</option>' + retorno1;
var ret2 = retorno1 + '<option value="0">------ N/A ------</option>';
if($("#departamento_drop option:selected").val() > '0'){
jQuery("#departamento_drop").html(ret2);
}else{
jQuery("#departamento_drop").html(ret1);
}
});
});

after 9 hours of work on it, I done this solution but still I need to find how to remove the selected option from retorno1 to not be duplicated, and for sure if there is any other idea better please share. thank you
$("#user_number_id").val(function(){
var selecionado = $(this).val();
jQuery.get("<?php echo base_url().'departamentos/filter_departamento/'; ?>"+selecionado,
function(retorno1){
var i = 0;
var pre = retorno1 + '<option value="0">------ N/A ------</option>';
var count = $($.parseHTML(retorno1)).filter('option').length;
var dep_dr = $("#departamento_drop option:selected").val();
for(i=0; i < count; i++){
var val_drop = $($.parseHTML(retorno1)).filter("option[value*='" + i + "']").val();
var text_drop = $($.parseHTML(retorno1)).filter("option[value*='" + i + "']").text();
if (val_drop == dep_dr){
jQuery("#departamento_drop").html("<option value ='"+val_drop+"' selected='selected'>"+text_drop+"</option>"+pre);
}else if(dep_dr == '0'){
jQuery("#departamento_drop").html("<option value ='"+dep_dr+"' selected='selected'>------ N/A ------</option>"+pre);
}
}
});
});

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.

HTML5 Local Storage store form data for select box where multiple values are selected

I have a form which saves a users preferance in local storage, it can be seen in this fiddle or below.
With what I have so far there are 2 main problems.
On clicking the save button you are meant to empty the myStorage then append what you have just selected in there, so they can see the live result of what they have clicked. It only remembers if you re-run the fiddle.
My biggest problem is that what I have is great for select fields with one option but in this case the user can select multiple, so what do I need to add to it so that the user can save multiple values to local storage so next time they load the page there multiple selections will be saved?
<form name="Filter">
<select multiple="1" id="filter">
<option value="111">Andrew</option>
<option value="222">Bill</option>
<option value="333">Charles</option>
<option value="444">Dikembe</option>
<option value="555">Edward</option>
</select>
</form>
<div id="store">click to store</div>
<br>
<h3>People I have stored</h3>
<div id="myStorage"></div>
JS
var iSelectedTitle = localStorage.getItem('title');
var iSelectedVal = localStorage.getItem('value');
console.log("iSelectedTitle: " + iSelectedTitle);
console.log("iSelectedVal: " + iSelectedVal);
$("#filter option").each(function () {
if ($(this).val() == iSelectedVal) {
$(this).attr("selected", "selected");
}
});
$("#store").click(function () {
var mytitle = $("#filter option:selected").text();
var storedTitle = localStorage.setItem("title", mytitle);
console.log("mytitle: " + mytitle);
console.log("storedTitle: " + storedTitle);
var myValue = $("#filter option:selected").val();
var storedValue = localStorage.setItem("value", myValue);
console.log("myValue: " + myValue);
console.log("storedValue: " + storedValue);
if (iSelectedTitle != "undefined") {
$('#myStorage').empty().append(iSelectedTitle);
}
});
if (iSelectedTitle != "undefined") {
$('#myStorage').append(iSelectedTitle + ' - <a target= "_blank "href="http://www.example.com/' + iSelectedVal + '">View profile</a>');
}

You can add multiple options to an array using map of jQuery :
var optArray = $("#filter option:selected").map(function () {
return {
"title": this.innerHTML,
"value": this.value
}
}).get();
This will give you a nice array like this :
[
{ "title": "Andrew", "value": "111" },
{ "title": "Bill", "value": "222" },
{ "title": "Charles", "value": "333" }
]
For adding to localStorage :
$("#store").click(function () {
//get the selected options in the form of an array
var optArray = $("#filter option:selected").map(function () {
return {
"title": this.innerHTML,
"value": this.value
}
}).get();
console.log(optArray);
//set that to localStorage
localStorage["optArray"] = JSON.stringify(optArray);
//refresh myStorage
getFromStore();
});
For refreshing the myStorage container with your newly added people, you'll have to call this handler as the last event inside the `click event (above).
var getFromStore = function () {
//check if store values are null, if null, make store =[]
var store = [undefined, null].indexOf(localStorage["optArray"]) != -1 ? [] : JSON.parse(localStorage["optArray"]);
console.log(store);
//empty container before u put values
$('#myStorage').html('');
//check if store is empty
if (store.length != 0) {
//loop over store if it aint empty and append the content into myStorage div
for (var k in store) {
var str = '<div>' + store[k]["title"] + ' - <a target= "_blank" href="http://www.example.com/' + store[k]["value"] + '">View profile</a></div>';
console.log(store[k]);
$('#myStorage').append(str);
}
} else {
//do this if no data is found in localStorage
$("#myStorage").html("No people found in store");
}
}
Then, in DOM ready, call getFromStore to refresh myContainer on load of the page:
$(function() {
getFromStore();
})

EDIT
To select the checkboxes by default, add the folowing line in the getFromStore function :
$("[value=" + store[k]["value"] + "]","#filter").prop("selected", true); //find the option with the corresponding value and select it

You could save multiple values in an array,
var myValuesArr = ['one','two','three'];
The array would need to be serialized before it is saved to localStorage
var serialVals = JSON.stringify(myValuesArr);
localStorage.setItem('numbers',serialVals);
Likewise, the stored data will have to be unserialized after it is read back
var serialVals = localStorage.getItem('numbers');
var myValuesArr = JSON.parse(serialVals);
