Values not getting saved onsubmit of form using local storage

Values not getting saved onsubmit of form using local storage - javascript

I want to capture 2 values (product name and energy consumption)from a form and store it using local Storage.
OnClick I want to display the stored values on the side of the form.
What is working
local storage is getting set.
Issues (in the commented function compareSetup)
1) My guess is I am not getting the selected product nor the energy values from the form itself.
2) wrote the display logic but getting error on that line
Uncaught SyntaxError: Unexpected identifier.
I tried 2 different ways. I am newbie hence trying different syntax
3) Resources tab in Chrome shows
callAnnual as undefined
callProduct as 0
4) alerts inside function did not work
I missing something. either logically or syntaxwise or both.
Can some one guide me please. Thanks for your time.

Your scope access of '$' as undefined should be a dead give away as to why the remainder of the code is not working. Once you have called the '$' bit of code within the proper scope it will work.

How to match user input with array data in JavaScript

I'm new in learning HTML, JavaScript and CSS. I'm stuck at this JavaScript code.
I'm trying to match user input on the searchbar with some city array list I already prepared, when the search result match the script will change the display style of element into showing the result of their search value, but until now the result always showing false value.
Is there any better way to do this? Is there something wrong with my code?
function searchRespond() {
if (document.getElementById("myInput").value.match(cities))
{
document.getElementById("areaCovered").style.display = "block";
}
else {
document.getElementById("areaNotCovered").style.display = "block";
document.getElementById("searchResult").innerHTML = document.getElementById("myInput").value;
}
}
var cities = ["Banda Aceh", "Bandar Lampung", "Banyuwangi", "Bandung", "Bali", "Batam", "Batu", "Bekasi", "Bengkulu", "Binjai", "Blitar", "Bogor", "Bukittinggi", "Cimahi", "Cirebon", "Denpasar", "Depok", "Dumai", "Gunungsitoli", "Jakarta", "Jambi", "Kediri", "Langsa", "Lhokseumawe", "Lombok", "Lubuklinggau", "Madiun", "Magelang", "Malang", "Medan", "Metro", "Mojokerto", "Padang", "Padang Sidempuan", "Padangpanjang", "Pagar Alam", "Palembang", "Pangkal Pinang", "Pariaman", "Pasuruan", "Payakumbuh", "Pekalongan", "Pekanbaru", "Pematangsiantar", "Prabumulih", "Prigi", "Probolinggo", "Sabang", "Salatiga", "Sawahlunto", "Semarang", "Serang", "Sibolga", "Solo", "Subussalam", "Sukabumi", "Sumbawa", "Sungaipenuh", "Surabaya", "Surakarta", "Tangerang", "Tangerang Selatan", "Tanjungbalai", "Tanjungpinang", "Tasikmalaya", "Tebing Tinggi", "Tegal", "Yogyakarta"];

To do what you require you can use filter() to match the user's input to values in your array. You would be best to perform a case-insensitive match, which can be done by converting both values to the same case.
Note that this logic sets the notifications as hidden before the logic runs, so that the previous state of the search is removed.
In addition, I made a couple of improvements to the code. Firstly I stored the relevant elements in variables instead of accessing the DOM every time. This is slightly more performant, and makes the code a lot easier to read. I also used addEventListener() to bind events instead of inline event handlers in the HTML, which are bad practice and shouldn't be used. Lastly I converted the <h> elements to <h2 /> in this demo, as there is no <h> element in HTML.

You can use javascript includes().

console.log("Exists");

suggest to validate input by making first letter uppercase and rest lowercase to match the array values
with javascript indexOf function

var area2search = input.charAt(0).toUpperCase() + input.slice(1).toLowerCase(); /* make fist letter capital and rest lower case to match array */
if (cities.indexOf(area2search) > -1) {
document.getElementById("areaCovered").style.display = "block";
//In the array!
} else {
document.getElementById("areaNotCovered").style.display = "block";
document.getElementById("searchResult").innerHTML = document.getElementById("myInput").value;
}
}

I want to check the timezone value, and the two toggle on/off buttons and then output the alert "your settings have been saved to local storage. I know I have to save toggle buttons state as checked, and I researched similar questions on stack, but nothing seems to work.
The second paragraph of code is the one I am working one.

found console error on:

trying to get the value of a random number and put it in a specific div

I'm trying to display random number in a specific div or grid do i need to store number first i would like some advice on how i can achieve this. for example if random number is 4 i would like that value in div 4, then if my next random number is 10 place it in div 10
browser example
function lottoNumbers() {
var lottoNums = [];
for (var i = 0; i < 1; i++) {
var temp = Math.floor(Math.random() * 12);
if (lottoNums.indexOf(temp) == -1) {
`enter code here`
lottoNums.push(temp);
document.getElementById('square' + i).innerHTML = lottoNums[i];
} else {
i--;
}
}
}
<body bgcolor="lightblue">
<h1>
<center>GENERATE LOTTO NUMBERS</center>

<div class="divContainer">
<div id=square0 class=num></div>
</div>
</br>
<div class="hej">

Your number wasn't being placed on the right spot as You generated the temp variable which is the random number, but have addressed it to variable i which is the iterator of the for loop. This way, if You would generate 3 random numbers, they would be placed in the divs square0, square1, square2 when they actually should be placed in the divs 'square'+temp that correspond to the actual generated number. Please see my example:
document.getElementById ("btn").addEventListener ("click", lottoNumbers, false);
function lottoNumbers() {
var lottoNums = [];
for (var i = 0; i < 1; i++) {
var temp = Math.floor(Math.random() * 12) + 1;
lottoNums.push(temp);
document.getElementById('square' + temp).innerHTML = lottoNums[i];
document.getElementById('square0').innerHTML = lottoNums[i];
}
}
.num {
border: 1px solid;
width: 20px;
height: 20px;
margin: 2px;
}
.nums {
border: 1px solid;
width: 20px;
height: 20px;
margin: 2px;
float: left;
}
body {
background-color: lightblue;
}
.hej{

width: 120px;
height: 30px;
clear: both;
}
.hei{

clear: both;

width: 120px;
height: 30px;
clear: both;
}

<h1>

</div>
<div class="hej">

<div id="square11" class="nums"></div>
<div id="square12" class="nums"></div>
</div>
<input id="btn" class="knapp" type="button" value="lotto"">

You can just change
document.getElementById('square' + i).innerHTML = lottoNums[i];
to
document.getElementById('square' + lottoNums[i]).innerHTML = lottoNums[i];
to put each random number in the div matching that number.

Form to fill excel spreadsheet

I've been trying to build an application to submit form selections to an existing spreadsheet on a local machine. This is intended for a windows machine, but I am working on ubuntu, and don't have access to a windows development environment. With this, I'm trying to parse an excel document, find the bottom row, capture the 'ingredients' list, or other form values, then insert the value of the hash into the excel column and save the changes to the document. Any suggestions on where I should start would be great.
-- Thanks a million

Are you not looking at this from the wrong angle?
Rarely would you try to access an Excel document directly, since the quantity of 'irrelevant' data is huge (data needed by Excel to reconstruct the page itself, but not directly related to the data the user is storing - meta-data if you will; i.e. font used, size of font, etc.).
Usually you would output the data to a CSV and allow the user to import the data into any spreadsheet program, which gives you greater flexibility and is simpler to code.
In terms of adding the data, you could easily open the existing CSV and append new data, or search the file and insert the data where required. However, if others are to use the CSV then I'd save the data in a single-table database as well as in the CSV. Then you simply construct a new CSV each time, overwriting any existing file if necessary.
No code help here at present, and I might be wrong, but this is the approach I have used and seen used.

How do I make my iframe responsive for all devices?

I am not an expert in HTML, CSS, or JavaScript, but I have this website that needs to be responsive on all devices. However, it does not seem like it is working for some reason and instead creates major gaps of white space when I view the website on a mobile web browser:
Here is the code for it:

Looks like your iframe is injected by JavaScript so I personally suggest adding a setInterval() to your code to monitor the iframe element. Once the iframe element is available, get the body in the iframe and set it's margin to 0.
$(function() {
$('#test').append('<iframe src="http://www.w3schools.com"></iframe>');
var timer = setInterval(function() {
$('iframe').load( function() {
$('iframe').contents().find("head").append($("<style type='text/css'>body{margin:0;}</style>"));
clearInterval( timer ); // Clear the interval
});
}, 10);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="test">
</div>
