Local storage add item - javascript

I am trying to build a little web app using local storage. I can add and delete items . I want to add new item to local storage but I always fail. When i try to add a new item it always show "no localStorage in window".
So I edit it (still not works) :
function addStorage() {
var key = document.getElementById('storageKey');
var data = document.getElementById('storageData');
var nic = document.getElementById('storageNic');
//localStorage setItem
if ("localStorage" in window) {
localStorage.setItem(key.value, data.value, nic.value);
location.reload();
} else {
alert("no localStorage in window");
}
function removeStorage() {
var key = document.getElementById('removeKey');
//localStorage removeItem
if ("localStorage" in window) {
if (localStorage.length > 0) {
localStorage.removeItem(key.value);
location.reload();
}
} else {
alert("no localStorage in window");
}
}
function clearStorage() {
//localStorage clear
if ("localStorage" in window) {
if (localStorage.length > 0) {
localStorage.clear();
location.reload();
}
} else {
alert("no localStorage in window");
}
}
window.onload = function () {
var localhtml = "";
//localStorage key and getItembr
for (var i = 0; i < localStorage.length; i++) {
localhtml += "<li>" + localStorage.key(i) + " " + localStorage.getItem(localStorage.key(i)) + "</li>";
}
document.getElementById('localStorageData').innerHTML = localhtml;
}
}
HTML:
<script>
function addTextTag(text){
document.getElementById('storageKey').value += text;
}
</script>
<input type="text" id="storageKey">
<input type="text" id="storageData">
<input type="text" id="storageNic">
<input type="button" id="save" value="SAVE" onclick="addStorage();return false;">
<input type="button" id="clear" value="Clear" onclick="clearStorage(); return false;">
<div id="localStorageData"></div>

Given that localStorage isn't defined in window, your browser probably doesn't support it. See Mozilla's browser compatibility matrix for reference.
I've concocted a jsFiddle for you try:
HTML
<input id="storageKey" value="key"></input>
<input id="storageData" value="value"></input>
<input id="storageNic" value="nic"></input>
<div id="localStorageData"></div>
JavaScript
function addStorage() {
console.log("Add storage");
var key = document.getElementById('storageKey');
var data = document.getElementById('storageData');
var nic = document.getElementById('storageNic');
//localStorage setItem
if ("localStorage" in window) {
console.log("Setting item " + key.value + " to " + data.value +
" in localStorage");
localStorage.setItem(key.value, data.value, data.
} else {
alert("no localStorage in window");
}
}
function removeStorage() {
var key = document.getElementById('removeKey');
//localStorage removeItem
if ("localStorage" in window) {
if (localStorage.length > 0) {
localStorage.removeItem(key.value);
location.reload();
}
} else {
alert("no localStorage in window");
}
}
window.onload = function () {
console.log("onLoad");
var localhtml = "";
addStorage();
//localStorage key and getItembr
for (var i = 0; i < localStorage.length; i++) {
localhtml += "<li>" + localStorage.key(i) + " " +
localStorage.getItem(localStorage.key(i)) + "</li>";
}
document.getElementById('localStorageData').innerHTML = localhtml;
};
If you try this fiddle, you should see a list of localStorage items. It works for me (Chrome 33.0.1750.117 m).

Dom Modification to clear Radio Button Info with Reset Button

So I have made a form that I can clear with a reset button. On this form, I have four radio buttons (that code is towards the top). When a button is selected, info comes up using "displayText".
<script type="text/javascript">
function textToDisplay (radioValue) {
console.log("textToDisplay + " + radioValue);
var displayText = "";
if (radioValue == "S") {
displayText = "Shortboards are under 7 ft in length.";
}
else if (radioValue == "L") {
displayText = "Longboards are usually between 8 and 10 ft.";
}
if (radioValue == "A") {
displayText = "Alternative boards defy easy aesthetic description.";
}
if (radioValue == "M") {
displayText = "Mid-Length surfboards are between 7 and 8 ft.";
}
return (displayText)
}
//DOM modification
function modifyDom(radioInput) {
console.log(radioInput.name + " + " + radioInput.value);
var displayText = textToDisplay(radioInput.value);
console.log(node);
var insertnode = document.getElementById("radioButtons");
var infonode = document.getElementById("info")
if (infonode === null) {
console.log("infonode does not yet exist");
var node = document.createElement("DIV");
node.setAttribute("id", "info");
node.className = "form-text infoText";
var textnode = document.createTextNode(displayText);
node.appendChild(textnode);
console.log(node);
insertnode.appendChild(node);
}
else {
console.log("infonode already exists");
infonode.innerHTML = displayText;
}
}
function checkboxesSelected (checkboxes, errorString) {
console.log("checkboxesSelected function");
var cbSelected = 0;
for (i=0; i<checkboxes.length; i++) {
if (checkboxes[i].checked) {
cbSelected += 1;
}
}
if (cbSelected < 2) {
return (errorString);
} else {
return "";
}
}
function validate (form) {
console.log("validate form");
var fail = "";
fail += checkboxesSelected(form.extras, "At least TWO fin setup needs
to be selected.\n")
if (fail == "") return true
else { alert(fail); return false }
}
</script>
When I reset my page using the button,
<input type="reset" name="reset" value="Reset">
the buttons themselves are cleared but the information that appeared from selecting the button is still visible. How can I reset the page so the displayText information is not visible? Thanks!
You can use an event listener for the reset event generated by clicking the reset button to execute cleanup code.
Here's a cut down example of the technique:
"use strict";
let myForm = document.getElementById("myForm");
let infoNode = document.getElementById("infonode");
let infoText = {
"S": "small board's are good",
"L": "large board's are good too"
};
myForm.addEventListener("change", function (event) {
if(event.target.name == "size") {
infoNode.innerHTML = infoText[ event.target.value];
}
}, false);
myForm.addEventListener("reset", function (event) {
infoNode.innerHTML = "";
}, false);
<form id="myForm">
<label> <input name="size" type="radio" value = "S"> Short</label><br>
<label> <input name="size" type="radio" value = "L"> Long</label><br>
<input type="reset" value="reset">
</form>
<div id="infonode"></div>
would suggest to remove the dynamically attached div#info:
document.getElementById("info").remove();
or blank it:
document.getElementById("info").innerHTML = "";

Javascript Alert when no matching results from search query

I created a Chicago employee search index and wanted to create an alert when there are no matching records found, but can't seem to be able to find out what value I need to put in for when it's empty. Ideally, when the function get's submitted and no results are found, it would push an alert onto the screen indicating no matching records found.
The alert right now is located in the submit function in the last bit of code posted
ChicagoEmployeesQuery = function(searchKey) {
var url,
url =
"https://data.cityofchicago.org/api/views/xzkq-xp2w/rows.json" +
"?search=key_word&jsonp=?";
this.query = url.replace("key_word", searchKey);
}
ChicagoEmployeesQuery.prototype.getList = function(callBack) {
$.getJSON(this.query, function(response) {
var i, results;
results = [];
for (i = 0; i < response.data.length; i += 1) {
row = {
name: response.data[i][8],
title: response.data[i][9],
department: response.data[i][10],
salary: response.data[i][14]
}
results.push(row);
}
callBack(results);
})

You can use onclick event on radio buttons:
http://www.dyn-web.com/tutorials/forms/radio/onclick-onchange.php
You could modify your code to use Buttons instead RadioButtons.
It should resemble the following:
<button name="b1" onclick="f19_SetFormCookie('Baseball')">Baseball</button>
<button name="b2" onclick="f19_SetFormCookie('Basketball')">Basketball</button>
<button name="b3" onclick="f19_SetFormCookie('Soccer')">Soccer</button>
<button name="b4" onclick="f19_SetFormCookie('Fencing')">Fencing</button>
Then you'll have to modify SetFormCookie function to accept the argument - based on which cookie will be set.

Display Contacts in Phonegap

I have to call `myFunction()`, in this code. I dont know where to call this function. Help me

I cannot catch what you want exactly.
if you want to generating phonenumber checkbox list when your app starts,
just call myFunction() in end of onSuccess() callback.
if you want another time, you should define a event handler that you want like below.
$("#PhonenumberListButton" ).click( function() { myFunction(); } );
and your code can occur index exception during loop.
Let's think about below.
each contact has 1 name but has 1 or more phone numbers
your code pushes each name into ar1 and also pushes each phone numbers of contact into ar2
so ar2.length can be greater than ar1.length
your generating display code use ar2.length for loop. it should make exception if any contact has 2 or more phonenumbers.
This's a reason of stop your loop in onSuccess().
Fixed Code
function onSuccess(contacts) {
for ( var i = 0; i < contacts.length; i++) {
name = contacts[i].displayName;
ar1.push(name);
ar2[i] = []; // array for multiple phone#.
for ( var j = 0; j < contacts[i].phoneNumbers.length; j++) {
number = contacts[i].phoneNumbers[j].value;
ar2[i].push(number);
}
}
myFunction(); // display phone numbers
}
function myFunction() {
$("#checkall").click(function() {
if ($(this).is(':checked')) {
$(":checkbox").attr("checked", true);
} else {
$(":checkbox").attr("checked", false);
}
});
for ( var i = 0; i < ar2.length; i++) {
if ( ar2[i].length ) { // avoid none phone# exception
var newTextBoxDiv = $(document.createElement('div')).attr("id",
'TextBoxDiv' + counter);
newTextBoxDiv.after().html(
'<input type="checkbox" value="'
+ ar1[i] + '"/>'
+ ar1[i] + " " + " " + ar2[i][0] + '</br>');
newTextBoxDiv.appendTo("#TextBoxesGroup");
}
}
}
