I get the following error: Uncaught SyntaxError: Unexpected end of input for line 1.
Here is the code:

$('<img src="./assets/'+selected+'.gif">').load(function() {

}
</script>

I don't understand what the issue is? Anyone know of the solution?
You are missing closing ) of your document-ready handler
Use
<script>
$( document ).ready(function() {
var array = [ 'body_bg_2','body_bg_3','body_bg_4','body_bg_5' ];
var selected = array[Math.floor(Math.random() * array.length)];
$('<img src="./assets/'+selected+'.gif">').load(function() {
$(this).appendTo('body');
});
}); //<== Here you have missed )
</script>
$(document).ready(function () {
var array = [ 'body_bg_2', 'body_bg_3', 'body_bg_4', 'body_bg_5' ];
var selected = array[Math.floor(Math.random() * array.length)];
$('<img src="./assets/' + selected + '.gif">').load(function () {
$(this).appendTo('body');
});
}); /* <--- this is your fail */

i think that the code 100% normal but why i got that Error????:
Uncaught TypeError: Cannot set property 'innerHTML' of null||
the code is:
<!DoCTYPE html>
<html lang="eng">
<head>
<meta charset ="utf-8">
<meta name="" content="">
<title></title>
<script>
function myAgeInDays() {
"use strict";
var myAge = 15;
return myAge * 365;
}
var daysCalc = myAgeInDays();
document.getElementById("test").innerHTML =
"Your Age In Days = "+ daysCalc+ " Day";
</script>
</head>
<body>
<button onclick="myinfo();">OK</button>
<h1 id="test">Ok</h1>
</body>
</html>
A few things can be done to improve this question:
Give some context, not the error the console prints out
Especially in the case of a very common js error. An example for your case could be "In form submission cannot select html element / selector is null in onclick function".
State some of the things you have tried
This will help you grow as a developer (the old teaching someone to fish story)
Some more tips here: https://stackoverflow.com/help/how-to-ask
In your case, the code you posted does not work (myinfo is not defined) and your code is in the <head> which is defined before the <p> is created. add it at the end of your body to ensure that all the elements are created. If you wanted to make a function handle the button click that contained the logic in your , you would write something like:
<body>
<button id="calcDays">OK</button>
<h1 id="test">Ok</h1>
<script type="text/javascript">
document.getElementById('calcDays')
.addEventListener('click', function () {
function myAgeInDays(days) {
return days * 365;
}
document.getElementById("test").textContent =
`Your Age In Days = ${myAgeInDays(15)} Days`;
});
</script>
</body>

I'm trying to make to do list but keep getting TypeError: Cannot read property 'addEventListener' of null. I moved my script file to the bottom of the body tag and still get the error. I also tried putting it at the top and using defer and that didn't work. I tried using If(todoBTN) { todoBTN.addEventListener('click', addTodo) and it got rid of the error but when I ran a console.log test I didnt't see it get logged.
const todoBTN = document.querySelector('addtodo-btn')
const inputTodo = document.querySelector('todo-input')
const todoList = document.querySelector('todo-list')
const form = document.querySelector('form')
todoBTN.addEventListener('click', addTodo)
form.addEventListener('submit' , event => {
event.preventDefault();
})
function addTodo() {
// Create Div
const divTodo = document.createElement('div')
divTodo.classList.add('itemsDiv')
// Create To Do Item
const todoItem = document.createElement('li')
todoItem.innerText = inputTodo.value;
divTodo.appendChild(todoItem)
todoList.appendChild(divTodo)
}

For class selector use . with in queryselector.See usage here
const todoBTN = document.querySelector('.addtodo-btn') // use . here for class
Same for others as well
const inputTodo = document.querySelector('.todo-input')
const todoList = document.querySelector('.todo-list')
const form = document.querySelector('.form')
You forget to add (.) in front of class name.

It says there is some problem in line 14
Where is your for loop for which you're an index i? If its removed intentionally then Tucson in your array has a space in the end. Use trim method.
Also language = "javascript" is wrong, its usually type="text/javascript"
The code should be like below:
enter code here
var cleanCities = ["Cheyenne ","Santa Fe ","Tucson ","Great Falls ","Honolulu"];
var cityToCheck = "Tucson";
for(var i=0; i<cleanCities.length; i++) {
if(cityToCheck === cleanCities[i].trim()){
alert('you are clean');
}
}

var discover = $filter("date")(new Date('08-24-2015'), "MM/dd/yyyy");
var occur = $filter("date")(new Date('06-07-2018'), "MM/dd/yyyy")
console.log(discover);
console.log(occur);
if (discover < occur) {
console.log('Discover less than occur');
} else {
console.log('No');
}
The result is always No to whatever value I assign to discover variable.
Did I compare it wrong?
I would advise you to use momentJS for date-time operations. It is much cleaner to implement.
To check if a certain time is before or after another time you could use their query functions
moment('2010-10-20').isBefore('2010-12-31', 'year'); // false
moment('2010-10-20').isBefore('2011-01-01', 'year'); // true
// Code goes here
var app = angular.module("app", []);
app.controller("BaseController", function($scope,$filter) {
var discover = $filter("date")(new Date('05-24-2015'), "MM/dd/yyyy");
var occur = $filter("date")(new Date('06-07-2018'), "MM/dd/yyyy")
console.log(discover);
console.log(occur);
if (discover < occur) {
console.log('Discover less than occur');
} else {
console.log('No');
}
});

I am trying to do a functionality like which happens on Twitter.
If I write #J in text box, a list should appear show with autocomplete starting names "Javascript", "Java", "JQuery".
When I select Jquery, it should display in a TextBox. I got the autocomplete code from Jquery. But I am unable to do this '#' functionality.
Below is the code which I have done till now:
<html lang="en">
<head>
<meta charset="utf-8">
<title>autocomplete demo</title>
<link rel="stylesheet" href="https://code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script src="https://code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
</head>
<body>
<label for="autocomplete">Select a programming language: </label>
<input id="autocomplete">
<script>
var tags = [ "Javascript", "Jquery", "Java" ];
document.getElementById('autocomplete').onkeypress = function (e) {
if (e.keyCode === 64 ) {
$( "#autocomplete" ).autocomplete({
source: function( request, response ) {
var matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( request.term ), "i" );
response( $.grep( tags, function( item ){
return matcher.test( item );
}) );
}
});
}
else
{
return false;
}
};
</script>
</body>
</html>
Try this:
http://jsfiddle.net/gtnf41co/5/
It checks input value starts with #:
if (this.value.search("#") == 0)
then takes out the # in the request term
request.term.replace("#", "")
You can do this with the autocomplete functionality by adding the # symbol to your tags:
<script>
var tags = [ "#Javascript", "#Jquery", "#Java" ];
$( "#autocomplete" ).autocomplete({
source: tags
});
</script>
