jQuery in Brackets Live Preview not working

jQuery in Brackets Live Preview not working - javascript

I have the beginning of I note taking website I am making as an experiment. It was working fine in the live preview from brackets, but then I saved the files and now none of the jQuery works. I think it is my code by it could also be something with Brackets since it only happened once I saved. Here is my code:
$(document).ready(function() {
var notes = [];
$("#newNoteWrapper").hide();
$(".text").focus(function() {
$(this).stop
$(this).animate({
marginLeft: "+=3%"
});
});
$(".text").blur(function() {
$(this).stop
$(this).animate({
marginLeft: "-=3%"
});
});
$(".button").hover(function() {
$(this).stop();
$(this).animate({
backgroundColor: "#108cb1"
}, 200);
}, function() {
$(this).stop()
$(this).animate({
backgroundColor: "#2DBEEB"
}, 200);
});
$("#newNoteButton").click(function() {
newNote(true);
});
$("#doneButton").click(function() {
newNote(false);
});
});
var newNote = function(enter) {
if enter {
$("#newNoteWrapper").show();
} else {
$("#newNoteWrapper").hide();
notes.push({
title: $("#noteTitle").val(),
body: $("#noteBody").val(),
});
}
}

Is there something wrong with this or should I try a different editor?

Textarea typing then show star rating

I have this star rate form and wanted you to start typing in the text area and it will show you the star rate form right away, but if the text area is empty, it will hide.
I discovered the following code:
<HTML>
<input placeholder="Enter some text" name="name" />
<p id="values"></p>
<JS>
const input = document.querySelector('input');
const log = document.getElementById('values');
input.addEventListener('input', updateValue);
function updateValue(e) {
log.textContent = e.target.value;
}
How can I combine this code into mine? Because it only does that now when I click outside of the text area and then show the stars. Please advise me on this!

I have taken the liberty of rewriting your code to accomplish what you are trying to do.
Two tips I want to give you:
Decouple the data layer with the presentation layer. You are mixing CSS styles in stylesheets, HTML and JavaScript. You are also having JavaScript as strings in your HTML attributes. This gets confusing quite rapidly! We have gone a long way since HTML4 and the 90's!
If you use a library, then use it. For example, you are using jQuery, then use it as it should instead of adding event handlers directly to the HTML attributes; jQuery has $(element).on(event, handler), don't do <div onclick="something(this)"></div>.
$(function MyFunction() {
const textInput = $("#review").on('input', function () {
if (textInput.val().length) {
rateStar.show();
} else {
rateStar.hide();
}
});
const ratingInput = $('#rating_input');
const rateStar = $("#rateYo").rateYo({
onSet: function(rating, rateYoInstance) {
let inputValue = textInput.val();
ratingInput.val(Math.ceil(rating)); //setting up rating value to hidden field
console.log( rating, inputValue );
// window.location.href = 'mailto:your#gmail.com?subject=' + rating + ' of 5' + '&body=' + bod;
}
}).hide();
});

How to show text on an image? (code is in question)

I am trying to learn coding in my freetime and have run into an issue. I am trying to have 'contact info' to be a on hover on profile picture so that it shows a way to contact me via phone, email, and shows my name. I'm hoping someone can help with this please.
Cut most of the HTML code in the process to allow post
var infoDivs = document.getElementsByClassName ('infoDivs');
var contactInfoDiv = document.getElementById('contactInfo');
function displayInfo(index) {
for (var i = 0; i < infoDivs.length; i++) {
infoDivs[i].style.display = 'none';
}
infoDivs[index].style.display = 'block';
}
function showcontactInfo() {
contactInfoDiv.style.display = 'block'
}
function hidecontactInfo() {
contactInfoDiv.style.display = 'none'
}
//line 12-18 is what should be my issue? Otherwise line 2? //

Make selected text bold/unbold with jQuery

I'm trying to make a text editor that can bold, italic and underline text using jQuery without using any HTML
The problem is that I can't make a selected text bold, the console log outputs "execCommand is not a function", am I doing something wrong? How can I achieve what I'm trying to do?
Here is my code:
(function ($) {
$.fn.text_editor = function(options) {
this.each(function() {
var buttons = {
buttons: ['bold', 'italic', 'underline']
};
var parametres = $.extend(buttons, options);
// generated html
$("body").html("<div class=\"container\">");
$("body").append("<h1 style=\"padding-left:55px;\">text editor</h1>");
$("body").append("<textarea rows=\"10\" cols=\"50\"></textarea>");
$("body").append("<br>");
$("body").append("<div class=\"buttons\"");
$("body").append("<button id=\"bold\">gras</button>");
$("body").append("<button id=\"italic\">italic</button>");
$("body").append("<button id=\"barre\">underline</button>");
// js
$("bold").execCommand("bold");
$("italic").execCommand("italic");
$("underline").execCommand("underline");
console.log($("bold"));
});
};
})(jQuery);
$(document).ready(function() {
$("textarea").text_editor()
});

After some searching, I came acrossthis article.
and this code pen. https://codepen.io/souporserious/pen/xBpEj
hope this helps.
$('.wysiwyg-controls a').on('click', function(e) {
e.preventDefault();
document.execCommand($(this).data('role'), false);
});

<b>Let's make a statement!</b>
<br>
<i>This is an italicised sentence.</i>
<br>
<u>Very important information.</u>
</div>
</div>
NOTE: this is not my code.

execCommand is an experimental function, and its an function of document and not html elements. You can however call this function as below -
$("#bold").document.execCommand("bold");
$("#italic").document.execCommand("italic");
$("#underline").document.execCommand("underline");

Text editing with jquery

I am creating a simple product list. I want to implement the editing of a product.
When I double-click on the product, I will be able to edit it. But i dont understand how i can do this. I hope, that you understand me because english is not my primary language. My code is here:
<div class="container">
<h1>Product List</h1>
<input type="text" name="newProduct" id="newProduct" placeholder="Enter your product here"/>
<ul id="productList"></ul>
<input type="checkbox" id="selectAll"/><label for="Select all">Select all</label>
<button id="deleteDoneProducts">Delete Selected</button>
</div>
CSS
* {
box-sizing:border-box;
}
body {
font-family: Tahoma, sans-serif;
}
.container {
margin:0 auto;
width:600px;
}
h1, #newProduct {
text-align: center;
width:598px;
}
#newProduct {
border:1px solid #999;
padding: 20px;
font-size: 28px;
box-shadow: 0px 0px 3px #888;
}
#productList {
list-style: none;
padding-left:0;
background-color: #F2F2F2;
}
.product {
padding: 15px 0px 15px 40px;
margin: 10px;
position: relative;

background-position: 0 0;
width:30px;
height: 30px;
position: absolute;
right: 20px;
top:13px;
display: none;
}
.remove:hover {
background-position: -34px 0px;
}
.product:hover .remove {
display: block;
}
#deleteDoneProducts {
float: right;
background-color: #a3d5df;
color: #fff;
padding: 10px;
border: none;
text-transform: uppercase;
font-weight: 900;
}
#deleteDoneProducts:hover {
background-color: #5fb5c7;
cursor: pointer;
}
jquery
function addNewProduct(e) {
if(e.keyCode == 13) {
var toAdd = $('input[name=newProduct]').val();
$('#productList').append('<li class="product"> <input type="checkbox" class="doneProduct"/>'+toAdd+'<div class="remove"></div><li/>');
$('#newProduct').val('');
e.preventDefault();
}
};
function deleteProduct() {
$(this).parent().remove();
};
function productDone() {
if (!$(this).is(":checked")){
$(this).parent().css({'textDecoration': 'none', 'color': '#000'})
} else {
$(this).parent().css({'textDecoration': 'line-through', 'color': '#999'});
};
};
function deleteAllSelected() {
$(".doneProduct:checked").parent().remove();
$('input[type="checkbox"]').removeAttr("checked");
};
function selectAllProducts() {
if (!$(".doneProduct").is(":checked")) {
$(".doneProduct").prop('checked', this.checked);
$(".doneProduct").parent().css({'textDecoration': 'line-through', 'color': '#999'});
} else {
$(".doneProduct").parent().css({'textDecoration': 'none', 'color': '#000'});
$(".doneProduct").prop('checked', this.checked);
}
};
$(function() {
$("#newProduct").on('keypress', addNewProduct);
$(document).on('click', ".remove", deleteProduct);
$(document).on('change', ".doneProduct", productDone);
$("#deleteDoneProducts").on('click', deleteAllSelected);
$("#selectAll").on('click', selectAllProducts);
$(".product").on('dbclick', editProductName);
})
https://jsfiddle.net/qp3nnfc5/5/ - this is fiddle)

Try this fiddle:
Change your addnewPRoduct function to:
function addNewProduct(e) {
if(e.keyCode == 13) {
var toAdd = $('input[name=newProduct]').val();
$('#productList').append('<li class="product"> <input type="checkbox" class="doneProduct"/><span>'+toAdd+'</span><div class="remove"></div><li/>');
$('#newProduct').val('');
e.preventDefault();
};
};
and Add this to your JS:
$("#productList").on("dblclick","li",function(){
$(this).find('span').attr("contentEditable",true)
})
Update :
Updated fiddle
Add this to JS
$("#productList").on("keypress","li",function(e){
if(e.which == 13){
e.preventDefault()
$(this).find('span').attr("contenteditable",false)
return;
}
})
