Can someone please explain why this code isn't working?
(it has been simplified for this example)
$(document).ready(function () {
var test = 'broken';
test = test.replace('broken','working');
console.log(test); // working
var field = $('[for="tournament_name"]').html();
console.log(field); // Tournament Name:
console.log(typeof field); // string
field = field.relpace(':',''); // Uncaught TypeError: undefined is not a function
});
I don't understand why it is saying replace() is undefined?
I did read through the docs, what am I missing here?

Maybe it's a typo:
relpace --> replace

const company = "Big Bucks co.";
let profit = 900;
let financeManager = "Richard";
if (profit < 1000) {
var richardFired = true;
var financeManager = "Fay";
}
console.log(company);
console.log(financeManager);
console.log(richardFired);
Hey, I'm practicing my code! I'm trying to figure out why I am getting
SyntaxError: Identifier 'financeManager' has already been declared
I want the console.log(financeManager); to log Fay, but it is logging Richard.
Thanks, in advance!
remove var inside if, you're declaring it again

I'm trying to make an alert, that prints the value of a variabile, here is my attempt.
var username = prompt("I'm LaunchBot, what's your name?");
var print = alert() ;
alert() is a function. It take a parameter between the parenthesis. So just insert your variable username between them:
var username = prompt("I'm LaunchBot, what's your name?");
alert(username) ;
As suggested in the comment alert() doesn't return anything so do not add a variable assignment before.

This is happening on an angular application I'm building. If a user enters 80 into an HTML input, it always seems to get this comparison wrong.
var x = '80';
var y = 150.9800;
/* Returns incorrect answer */
if (parceFloat(x) < y) {
return true;
} else {
return false;
}
You need to use ParseFloat() not parceFloat() ...
parceFloat is not an existing function.
parceFloat() is not a function, the function is parseFloat()
A simple typo is all the error there is.

var data = {};
data.info.id = "alpha";
This logs to the console: "TypeError: data.info is undefined".
Well that's great and all but I need to store a value in data.info.id. Isn't that what objects are supposed to do?
This should produce an object that looks like this:
data: {
info: {
id: "alpha"
}
}
Is data.info = {} really a necessary step?
In response to Patrick Evans - that's an unrelated question.
Well there is another way. That's putting the info-object directly in the data-object like this:
var data = {
info: {}
}
data.info.id = "alpha";
console.log(data);

This code should working, but I have no idea why it is not working at all.
HTML:
<p><input type="file" size="50"></p>
<p><input type="button" value="test" onclick="test()"></p>
JavaScript:
test = function() {
console.dir(document.querySelector('input[type="file"]').value);
var a = document.querySelector('input[type="file"]').vaule;
console.dir(a);
};
The first console.dir can successfully display the selected file filename
whereas I store it in var a is return undefined, whats happended?
fiddle: jsfiddle.net/eb5tuo7o
With the console log you're using .value but when you're storing it you've misspelled it as .vaule.
test = function() {
console.dir(document.querySelector('input[type="file"]').value);
var a = document.querySelector('input[type="file"]').value;
console.dir(a);
};
There is no such thing as "vaule"
You can access html elements value by using
document.querySelector('input[type="file"]').value;
And if you are using jquery it's even simpler
$("input[type=file]").val();
