So I was programming my search bar and I can't quite know why it's not working. I am wanting when a user types "forums" it says a message and when they click okay it sends them to the forums, but I was testing to see if it would display the alert it and I couldnt get it to say anything.

if(mySearchBar = "forums")
document.getElementById('submit');
alert("you have tried accessing forums")
else
alert("You have entered invalid text, try again.")
}
One obvious mistake is that you forgot curly braces in your if / else statement (and semicolons).
if(mySearchBar.value == "forums") {
document.getElementById('submit');
alert("you have tried accessing forums");
} else {
alert("You have entered invalid text, try again.");

I have a code to generate a normal date time picker, but it is throwing me this error Uncaught TypeError: jQuery(...).datetimepicker is not a function
Can anyone help me, i guess it is because of arrangment of links and bootstrap , but i don't have a clear picture of it.
below is my code
<html>
<head>

Press F11, open the Chrome debug, go to Network > JS tab and check if any of the included js libraries return a 404 status. Maybe you misspelled a script name or URL path.
You can also try to include the libraries directly from CDNs:

<script src="https://code.jquery.com/ui/1.13.1/jquery-ui.js"></script>
<script>
$( function() {
$('#datevalue').datetimepicker();
$('#completed').datetimepicker();
} );
</script>
</head>
I dont know whether your datetimepicker library is loading or not.
You can use following CDN.
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery-datetimepicker/2.5.4/build/jquery.datetimepicker.full.min.js"></script>
Following code will load todays date and will show datepicker on input click
<script>
$(document).on("click", "#datevalue" , function() {
$(this).datetimepicker({
timepicker:false, format:"d-m-Y","setDate": new Date(),
}).focus();
});
</script>
When text is written into the input box and then the button is clicked, I want the text (value) to be added to the array I have created for it (the array is called 'subject'). The text (value) from the input box is not being added... why?
var subject = [];
function addSubjects() {
namesInputted = document.getElementById('namesInputter').value;
subject.push(namesInputted);
console.log(subject);
}

Actually, You code is working. The input value is appending to the array. But the Issue is, You are using form. So when you click the button, It will submit the form right after add the value to array. So page will refresh and the array will become empty.
Just remove form tag, if you don't want to submit data.
var subject = [];
function addSubjects() {
namesInputted = document.getElementById('namesInputter').value;
subject.push(namesInputted);
console.log(subject);
}

If you want to use form submit with jQuery, you can use like this:
Html
<form>
<input type="text" id="namesInputter" value="">
<button type="submit">Add Player</button>
</form>
JavaScript
var subject = [];
function addSubjects(e) {
}
$("form").submit(function(e){
e.preventDefault();
namesInputted = document.getElementById('namesInputter').value;
subject.push(namesInputted);
console.log(subject);
});
I am using Google App Script to build a little web app. I'm just at the very start and the page charges well on both Chrome and Firefox but I can't get anything to happen on click of the log in button. I don't get any log to the logger, neither do I get the alert to pop up. Does anyone have any idea why?
This it the HTML of HTML_StockManagementLogInPage:

I tried earlier to break down my code with the fuction InsertHTMLScript that I have written in the code, inserting <?!= InsertHTMLScript("HTML_CSS"); ?> into the HTML code and it didn't work either. I don't known if it's related but I just resolve not to use it to make things easier.
Thank you in advance
You misspelled getElementById
You have:
document.getElementByID('LogInButton');
It should be:
document.getElementById('LogInButton');
Here is the official docs: https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementById
I have something like this for index.html
<!DOCTYPE html>
<html>
<head>
<title>Game</title>
<link rel="stylesheet" type="text/css" href="style.css"/>
<link rel="stylesheet" type="text/css" href="css/font-awesome.min.css" />
</head>
<body>
<h2 class= "question1">How many letters are in "hello" ?</h2>
<form class="answers">
<input type="submit" name="answer1" value="1" class="answer" onclick="wrongAnswer(this.name)">
</form>
</body>
<script src="JavaScript.js"> </script>
</html>
and this is the JavaScript.js
function wrongAnswer(name)
{
document.getElementsByName(name)[0].style.backgroundColor = "red";
}
when the button is pressed the background gets red but it doesn't last. It goes away in about 1 second. I want it to be changed as long as the page is not refreshed. How to do that ?
Thanks for your time
You are using a submit button input. When it is pressed, the browser tries to send the form's data to a server and this reloads the page. You can use a button element instead:
<h2 class= "question1">How many letters are in "hello" ?</h2>
<button name="1" onclick="wrongAnswer(this.name)">1</button>
Your form element is triggering a page refresh on submission of it's contents.
This is normal.
Typical practice is to intercept said form's onSubmit event and preventDefault().
See below for a practical example.
Note the handleSubmit() and onSubmit references in the respective JavaScript and HTML portions of the following code.
// Handle Submit.
function handleSubmit(event) {
event.preventDefault() // Prevent Default.
}
// Wrong Answer.
function wrongAnswer(name)
{
document.getElementsByName(name)[0].style.backgroundColor = "red";
}

I can't seem to find a way to get the javascript to take the inputted name I put in the box to make it appear where the paragraph is as output when the onblur event happens.

I want to know why my javascript is wrong and why it won't show my name when the onblur event happens.
This is quite easily done with JQuery
<input type="text" id="namebanner" name="namefield" />
<script>
$(function(){
$('#namebanner').blur(function(){
$('#p1').text( $(this).val() );
});
});
</script>
or in plain javascript
<script>
function showname(){
var x = document.getElementById("namebanner");
document.getElementById("p1").innerHTML = x.value;
}
</script>
