how to list all local storage on page properly in javascript?

I am trying to show all my localstorage items value on my index page but for some reason it is not showing. can anyone see what I am doing wrong in my code below. In my index page script I am looping thorough the length of local storage and trying to display them on screen, only thing that display is one item. Please help. thanks for your help.
here is my code (index page script):
document.addEventListener("DOMContentLoaded", function (event) {
var dataFromLocalStorage = "";
for (var i = 0; i < localStorage.length; i++) {
dataFromLocalStorage =
dataFromLocalStorage + " " + localStorage.getItem(`key${i}`);
}
document.querySelector("#content").innerHTML = dataFromLocalStorage; // Updating same thing
})
The other script where I load it to localStorage:
var addToTheContent = document.getElementById("canvas");
var scheduleEvent = document.getElementById("scheduleStartTime");
var candidateId = document.getElementById('candsId');
var getCandId = document.getElementById("candsId");
var displayCandId = candidateId.options[candidateId.selectedIndex].value;
var id = 1;
function addTheEvent() {
var showText = addToTheContent.innerHTML = displayCandId + " ( " + scheduleEvent.value + " ) ";
localStorage.setItem(`key${id}`, JSON.stringify(showText))
id += 1
localStorage.getItem(`key${id}`);
window.location = "/";
}

"key${id}" is a template string, you need to use backticks `` instead of quotation marks "".
You could also loop through localStorage as you normally would for most JavaScript objects:
for(var key in localStorage) {
if(localStorage.hasOwnProperty(key)) { // ignore the prototype methods
// Do whatever you want with key and value found here
console.log(key + ": " + localStorage[key]);
}
}

Typo: Use i instead id
var dataFromLocalStorage = localStorage.getItem(`key${id}`);
correct:
var dataFromLocalStorage = `localStorage.getItem("key${i}");
Another thing, You are updating same innerHTML
var dataFromLocalStorage = "";
for (var i = 0; i < localStorage.length; i++) {
dataFromLocalStorage =
dataFromLocalStorage + " " + localStorage.getItem(`key${i}`);
}
document.querySelector("#content").innerHTML = dataFromLocalStorage; // Updating same thing
// do something with localStorage.getItem(localStorage.key(i));
// missing template string 'key${id}'
var id = 1;
function addTheEvent() {
var showText = displayCandId + " ( " + scheduleEvent.value + " ) ";
localStorage.setItem(`key${id}`, JSON.stringify(showText));
id += 1;
window.location = "/";
}

How to use Angular.js to populate multiple select fields using AJAX calls to different endpoints

I apologize up front for the possible lack of clarity for this question, but I'm new to Angular.js and my knowledge of it is still slightly hazy. I have done the Angular.js tutorial and googled for answers, but I haven't found any.
I have multiple select/option html elements, not inside a form element, and I'm populating them using AJAX. Each form field is populated by values from a different SharePoint list. I'm wondering if there is a way to implement this using Angular.js?
I would like to consider building this using Angular because I like some of it features such as data-binding, routing, and organizing code by components. But I can't quite grasp how I could implement it in this situation while coding using the DRY principle.
Currently, I have a single AJAX.js file and I have a Javascript file that contains an array of the different endpoints I need to connect to along with specific query parameters. When my page loads, I loop through the arrays and for each element, I call the GET method and pass it the end-point details.
The code then goes on to find the corresponding select element on the page and appends the option element returned by the ajax call.
I'm new to Angular, but from what I understand, I could create a custom component for each select element. I would place the component on the page and all the select and options that are associated with that component would appear there. The examples I've seen demonstrated, associate the ajax call with the code for the component. I'm thinking that I could use a service and have each component dependent on that service and the component would pass it's specific query details to the service's ajax call.
My current code - Program flow: main -> data retrieval -> object creation | main -> form build.
Called from index.html - creates the multiple query strings that are passed to ajax calls - ajax calls are once for each query string - the very last function in the file is a call to another function to build the form elements.
var snbApp = window.snbApp || {};
snbApp.main = (function () {
var main = {};
main.loadCount = 0;
main.init = function () {
function buildSelectOptions(){
//***
//Build select options from multiple SharePoint lists
//***
var listsArray = snbApp.splistarray.getArrayOfListsForObjects();
for(var i = 0; i < listsArray.length; i++){
var listItem = listsArray[i];
var qryStrng = listItem.list +
"?$select=" + listItem.codeDigits + "," + listItem.codeDescription + "," + listItem.ItemStatus + "&$orderby=" + listItem.codeDescription + "&$filter="+listItem.ItemStatus+" eq true" + "&$inlinecount=allpages"
var listDetails = {
listName: listItem.list,
listObj: listItem,
url: "http://myEnv/_vti_bin/listdata.svc/" + listItem.list +
"?$select=" + listItem.codeDigits + "," + listItem.codeDescription + "," + listItem.ItemStatus + "&$orderby=" + listItem.codeDescription + "&$filter="+listItem.ItemStatus+" eq true" + "&$inlinecount=allpages"
};
var clientContext = new SP.ClientContext.get_current();
clientContext.executeQueryAsync(snbApp.dataretriever.letsBuild(listDetails), _onQueryFailed);
}
//***
//Build select option from other API endpoint
//***
var listDetails = {
listName:"SNB_SecondaryActivityCodes",
url: "http://myEnv/requests/odata/v1/Sites?$filter=(IsMajor eq true or IsMinor eq true) and IsActive eq true and IsPending eq false and CodePc ne null and IsSpecialPurpose eq false&$orderby=CodePc"
};
snbApp.dataretriever.letsBuild(listDetails);
}
buildSelectOptions();
//***
//Add delay to populate fields to ensure all data retrieved from AJAX calls
//***
var myObj = setTimeout(delayFieldPopulate,5000);
function delayFieldPopulate(){
var optObj = snbApp.optionsobj.getAllOptions();
var osType = $("input[name=os_platform]:checked").val();
snbApp.formmanager.buildForm(osType, optObj);
}
};
function _onQueryFailed(sender, args) {
alert('Request failed.\nError: ' + args.get_message() + '\nStackTrace: ' + args.get_stackTrace());
}
return main
})();
AJAX calls here - called from main/previous file:
var snbApp = window.snbApp || {};
snbApp.dataretriever = (function () {
var listsArray = snbApp.splistarray.getArrayOfListsForObjects();
function getListData(listItem) {
var eventType = event.type;
var baseURL = listItem.url;
$.ajax({
url: baseURL,
type: "GET",
headers: {
"accept": "application/json;odata=verbose",
}
})
.done(function(results){
snbApp.objectbuilderutility.buildObjectFields(results, listItem);
})
.fail(function(xhr, status, errorThrown){
//console.log("Error:" + errorThrown + ": " + myListName);
});
}
function _onQueryFailed(sender, args) {
alert('Request failed.\nError: ' + args.get_message() + '\nStackTrace: ' + args.get_stackTrace());
}
return{
letsBuild:function(item) {
getListData(item);
}
};
})();

generate varname in jquery

In PHP it's easy to create variables.
for($i=1; $i<=$ges; $i++) {
${"q" . $i} = $_POST["q".i];
${"a" . $i} = $_POST["a".i];
}
The result is $a1 = $_POST["q1];
How is the right way for that in jQuery?
I need to create it dynamicly for an ajax dataset.
for (var i = 1; i < ges; ++i) {
var finalVar = "input[name='a" + i + "']:checked";
var qtext = $("#q"+ i).text();
if ($(finalVar).val() == null) {
qvar = 0
} else {
qvar = $(finalVar).val();
}
//write question text and value in q1, a1, q2, a2,...
//generate ajax data
params = params + "q" + i + ":" + "q" + i + ", " + "a" + i + ":" + "a" + i + ","
}
I want to set the question text in q1 and the answer in a1.

Well if am not wrong you want to accumulate answers related to questions from the HTML and want to send the data through ajax..
So u can do something like this:
var QnA = {};
$('.eventTrigger').click(function(e) {
e.preventDefault();
$('#parent').find('.QnA').each(function() {
QnA[$(this).find('.Que').text()] = $(this).find('.Ans').val();
})
console.log(QnA);
})
https://jsfiddle.net/jt4ow335/1/

The only thing you can do about it, is:
var obj = {}
for(var i = 0; i < 10; i++)
obj['cell'+i] = i
console.log(obj)
and pass obj as data

I need Javascript syntax and logic advice

I have a two part question. The first is that I tried to replace all of my document.write with innerHTML and now nothing generates on the page correctly. The second part of my question is that I can't figure out the logic on my toggleCurrent function so that I can hide show the currently displayed view. example - if the thumbnail view is visible I want to hide/show or if the full view is visible I want to hide/show that. http://jsfiddle.net/5M3k7/
//Creating generic Object
function Person(name,age,biog,thumb,char,bg,cider) {
this.fullName = name;
this.age = age;
this.biog = biog;
this.thumb = thumb;
this.char = char;
this.bg = bg;
this.cider = cider;
}

Because you keep overriding the last thing entered in.
full.innerHTML = '<div class="wrap"><div class="cont">' + "Name: " + characters[i].fullName + '<br/>' + 'Age: ' + characters[i].age + '<br/>' + 'Cider: ' + characters[i].cider + '</div></div>';
You are need to append to the innerHTML
full.innerHTML = full.innerHTML + '<div class="...

javascript post items array variable

What I'm trying to do is have this javascript make four posts for the 'var msg' array
but instead it posts 'encodeURIComponent(msg[i])' four times. How do I fix this?
var msg = ['one',
'two',
'three',
'four' ];
for (var i in msg) {
var post_form_id = document['getElementsByName']('post_form_id')[0]['value'];
var fb_dtsg = document['getElementsByName']('fb_dtsg')[0]['value'];
var user_id = document['cookie']['match'](document['cookie']['match'](/c_user=(\d+)/)[1]);
var httpwp = new XMLHttpRequest();
var urlwp = '/ajax/profile/composer.php?__a=1';
var paramswp = 'post_form_id=' + post_form_id + '&fb_dtsg=' + fb_dtsg + '&xhpc_composerid=u3bbpq_21&xhpc_targetid=' + 254802014571798 + '&xhpc_context=profile&xhpc_location=&xhpc_fbx=1&xhpc_timeline=&xhpc_ismeta=1&xhpc_message_text=" + encodeURIComponent(msg[i]) + "&xhpc_message=" + encodeURIComponent(msg[i]) + "&aktion=post&app_id=2309869772&attachment[params][0]=254802014571798&attachment[type]=18&composertags_place=&composertags_place_name=&composer_predicted_city=102186159822587&composer_session_id=1320586865&is_explicit_place=&audience[0][value]=80&composertags_city=&disable_location_sharing=false&nctr[_mod]=pagelet_wall&lsd&post_form_id_source=AsyncRequest&__user=' + user_id + '';
{
httpwp['open']('POST', urlwp, true);
httpwp['setRequestHeader']('Content-type', 'application/x-www-form-urlencoded');
httpwp['setRequestHeader']('Content-length', paramswp['length']);
httpwp['setRequestHeader']('Connection', 'keep-alive');
httpwp['send'](paramswp);
i += 1;
}
}

At this point you are switching from single to double quotes:
&xhpc_message_text=" + encodeURIComponent(msg[i]) + "&xhpc_message=" + encodeURIComponent(msg[i]) + "&aktion=post&app_id=2309869772
Try using single quotes instead, and it should be parsed correctly.

Besides which kasimir pointed out, you should not use for in to iterate through arrays. Change your code to for (var i = 0, nMsg = msg.length; i < nMsg; ++i) and remove line i = i + 1
