Javascript uploading file alignment - javascript

In the above image the delete button need to align properly. in my code it get align based on file name length.
<script>
var filelist = new Array();
updateList = function () {
var input = document.getElementById('fileUploader');
var output = document.getElementById('divFiles');
var HTML = "<table>";
for (var i = 0; i < input.files.length; ++i) {
filelist[i]=input.files.item(i).name;
HTML += "<tr><td>" + filelist[i] + "</td><td> <button ></button></td></tr>";
}
HTML += "</table>";
output.innerHTML += HTML;
}
</script>

Please try this.
table {
border-collapse: separate;
border-spacing: 0 3px;
width: 600px;
}

Try this
table
{
table-layout: fixed;
width: 300px;
}
td
{
border: 1px solid green;
word-wrap:break-word;
}
try jsfiddle

<style>
table {
border-collapse: separate;
border-spacing: 0 2px;
width: 600px;
table-layout: fixed;
}
tr:nth-child(1n) {
border: 2px solid;
background-color: #eceff1;
color: Black;
}
tr:nth-child(2n) {
border: 2px solid;
color: Black;
}
td {
padding-top: .5em;
padding-left: .5em;
padding-right: .5em;
padding-bottom: .5em;
}
input[type="file"] {
display: none;
}
.label1 {
padding: 3px;
background: #fff;
display: table;
color:black;
}
button {
background-image: url('../../Images/delete.ico');
background-size: cover;
padding-right:0px;
background-color: Transparent;
cursor: pointer;
border: none;
width: 30px;
height: 30px;
}
</style>
<script>
$(document).ready(function () {
$(document).on('click', "button", function (e) {
$(this).closest('tr').remove();
});
});
</script>
<script>
var filelist = new Array();
updateList = function () {
var input = document.getElementById('fileUploader');
var output = document.getElementById('divFiles');
var HTML = "<table>";
for (var i = 0; i < input.files.length; ++i) {
filelist[i]=input.files.item(i).name;
HTML += "<tr><td>" + filelist[i] + "</td><td><button ></button></td></tr>";
}
HTML += "</table>";
output.innerHTML += HTML;
}
</script>
In the above script the delete button is showing in fixed order but i want the file name to be aligned at left and delete button need to at right side corner.

javascript on a webpage displaying text wrongly

I have JS code on a webpage that loads questions in from mysql db and displays the text . What happens is that it cuts off words at the end of the line and continues the word on the next line at the start. So all text across the screen starts/ends at the same point.
This seems to be the code where it displays the text.
For example the text will look like at the end of a line 'cont' and then on next line at the start 'inue'.
How do i fix this?
var questions = <?=$questions;?>;
// Initialize variables
//------------------------------------------------------------------
var tags;
var tagsClass = '';
var liTagsid = [];
var correctAns = 0;
var isscorrect = 0;
var quizPage = 1;
var currentIndex = 0;
var currentQuestion = questions[currentIndex];
var prevousQuestion;
var previousIndex = 0;
var ulTag = document.getElementsByClassName('ulclass')[0];
var button = document.getElementById('submit');
var questionTitle = document.getElementById('question');
//save class name so it can be reused easily
//if I want to change it, I have to change it one place
var classHighlight = 'selected';
// Display Answers and hightlight selected item
//------------------------------------------------------------------
function showQuestions (){
document.body.scrollTop = 0; // For Safari
document.documentElement.scrollTop = 0; // For Chrome, Firefox, IE and Opera
if (currentIndex != 0) {
// create again submit button only for next pages
ulTag.innerHTML ='';
button.innerHTML = 'Submit';
button.className = 'submit';
button.id = 'submit';
if(quizPage<=questions.length){
//update the number of questions displayed
document.getElementById('quizNumber').innerHTML = quizPage;
}
}
//Display Results in the final page
if (currentIndex == (questions.length)) {
ulTag.innerHTML = '';
document.getElementById('question').innerHTML = '';
if(button.id == 'submit'){
button.className = 'buttonload';
button.innerHTML = '<i class="fa fa-spinner fa-spin"></i>Loading';
}
showResults();
return
}
questionTitle.innerHTML = "Question No:" + quizPage + " "+currentQuestion.question.category_name +"<br/>"+ currentQuestion.question.text;
if(currentQuestion.question.filename !== ''){
var br = document.createElement('br');
questionTitle .appendChild(br);
var img = document.createElement('img');
img.src = currentQuestion.question.filename;
img.className = 'imagecenter';
img.width = 750;
img.height = 350;
questionTitle .appendChild(img);
}
// create a for loop to generate the options and display them in the page
for (var i = 0; i < currentQuestion.options.length; i++) {
// creating options
var newAns = document.createElement('li');
newAns.id = 'ans'+ (i+1);
newAns.className = "notSelected listyle";
var textAns = document.createTextNode(currentQuestion.options[i].optiontext);
newAns.appendChild(textAns);
if(currentQuestion.options[i].file !== ''){
var br = document.createElement('br');
newAns .appendChild(br);
var img1 = document.createElement('img');
img1.src = currentQuestion.options[i].file;
img1.className = 'optionimg';
img1.width = 250;
img1.height = 250;
newAns .appendChild(img1);
newAns .appendChild(br);
}
var addNewAnsHere = document.getElementById('options');
addNewAnsHere.appendChild(newAns);
}
//.click() will return the result of $('.notSelected')
var $liTags = $('.notSelected').click(function(list) {
list.preventDefault();
//run removeClass on every element
//if the elements are not static, you might want to rerun $('.notSelected')
//instead of the saved $litTags
$liTags.removeClass(classHighlight);
//add the class to the currently clicked element (this)
$(this).addClass(classHighlight);
//get id name of clicked answer
for (var i = 0; i < currentQuestion.options.length ; i++) {
// console.log(liTagsid[i]);
if($liTags[i].className == "notSelected listyle selected"){
//store information to check answer
tags = $liTags[i].id;
// tagsClass = $LiTags.className;
tagsClassName = $liTags[i];
}
}
});
//check answer once it has been submitted
button.onclick = function (){
if(button.id == 'submit'){
button.className = 'buttonload';
button.innerHTML = '<i class="fa fa-spinner fa-spin"></i>Loading';
}
setTimeout(function() { checkAnswer(); }, 100);
};
}
//self calling function
showQuestions();
The website is on my local now but i can upload a screenimage if need be and the whole code of the webpage. Or is the issue in html?
edit: here is html/css code

I'm guessing that #question{ word-break: break-all; } is probably the culprit then? –
CB..yes that fixed it:)

Delete Row in table

My program basically displays books and other information about it. It also should be able to delete said book from the library and also the array in which it is stored. This is where my problem lies, I can't seem to delete that exact book from the display and the array. I tried using array.pop() and deleteRow(), but they only delete from the bottom. Thanks in advance for the help.
let myLibrary = [];
function book(name, author, pages, hasRead) {
this.name = name;
this.author = author;
this.pages = pages;
this.read = hasRead;
}

I would suggest a different approach. Instead of creating your new elements through string concatenation and .innerHTML (which has performance and security implications), use the DOM API to create your new elements and then just attach an event handler to the dynamically created cells that contain the X.
See additional comments inline below:
let headers = ["name", "author", "pages", "read"];
// Get your DOM references just once, not every time
// your event handlers execute and make sure to always
// reference the DOM element, rather than a property
// of the DOM element. That way, if you ever decide
// that you need a different property value, you won't
// have to scan the DOM for the element reference again.
let box = document.getElementById("box");
var btn = document.getElementById("new-book");
var modal = document.getElementById("myModal");
let closeModal = document.querySelector("span.close");
let name = document.getElementById('name');
let author = document.getElementById('author');
let pages = document.getElementById('pages');
let read = document.getElementById('dropdown');
var submit = document.getElementById("submit");
var modal = document.getElementById("myModal");
// DO NOT USE GETELEMENTSBYCLASSNAME and especially
// pass an idex to the first element within it:
// var span = document.getElementsByClassName("close")[0];
// Read this for details: https://stackoverflow.com/questions/54952088/how-to-modify-style-to-html-elements-styled-externally-with-css-using-js/54952474#54952474
// Instead, use .querySelector()
var span = document.querySelector(".close");
// Bind the "buttons" that show/hide the modal
// to a common function that does that.
btn.addEventListener('click', showHideModal);
closeModal.addEventListener('click', showHideModal);
function showHideModal(){
// No need for if/then. Just toggle the use of
// the .hidden CSS class
modal.classList.toggle("hidden");
}
submit.addEventListener('click', addBookToLibrary);
function book(name, author, pages, hasRead) {
this.name = name;
this.author = author;
this.pages = pages;
this.read = hasRead;

// No need to create variables to store new book references,

this in table.deleteRow(this) refers to a HTMLTableCellElement.
According to this doc : https://www.w3schools.com/jsreF/met_table_deleterow.asp
You'll need to pass an index instead.
Edit :
What about adding a data-row attribute to your rows where you put the index, and then getting this index by using element.dataset.row
E.G :
var html = "<table id=myTable1>";
html += "<tr data-row=" + $yourIndex + ">";
html += "<th class=top1>" + 'BOOK NAME'+ "</th>";
html += "<th class=top2>" + 'AUTHOR' + "</th>";
html += "<th class=top3>" + 'PAGES' + "</th>";
html += "<th class=top4>" + 'READ?' + "</th>";
html += "</tr>";
html += "</table>";
Use Splice to remove the element from the array. Use this link for your reference.
your way of explanation is a little bit vague to understand.

Inserting input field to chat popup

I am trying to learn by creating a chat bar. I have created a side nav bar with users and once I click the chat pop up box will open at the bottom. I want to add input field to that chatbox.
I tried to add the input field but I just got half success; it just gets added to the body not at the bottom of the chat box.

Interactive filter in HTML table multiselect

I am creating an HTML table dynamically from JSON objects. I am trying to create a filter for one of the table columns. It works fine but I cannot make it work with a multiselect function.
I tried adding this line:
$('.One1').multiselect();
in my script, in different places and it did not work.
var data = {"headers":["One","Two","Three","Four","Five","Six","Seven","Number1","Number2"],"rows":[["One1","Two1","Three1","Four1","Five1","Six1","Seven1",11,1000],["One1","Two1","Three2","Four1","Five1","Six1","Seven1", 22, 2000],["One2","Two1","Three1","Four2","Five1","Six1","Seven1", 77, 99]]};

When you declare your select, you can specify it is multiple:
var One = '<div class = "filter"><select class="One1" data-col="0"><option value="a">' + "One" + '</option>';
Change it to:
var One = '<div class = "filter"><select multiselect class="One1" data-col="0"><option value="a">' + "One" + '</option>';

For example if you want to filter "One1" in a table, you can simply use something like: $('td:contains("One1")').parent().hide(); and $('td:contains("One1")').parent().show(); as a filter.
If you want to filter specific column, combine something like this with your selector: $('table tr > td:nth-child(yourColumnNumberShouldBeFiltered), table tr > th:nth-child(yourColumnNumberShouldBeFiltered)'). These expressions may be used in a function binded to 'change' event of your multiselect.
UPDATE: Above method, because of using :contains(), filter all of "One1", "One12", and so on! For exact match filteration you can use something like this:
$('table tr > td:nth-child(yourColumnNumberShouldBeFiltered)').filter(function() {
return $(this).text() == "yourExactTextToFilter";
}).parent().hide();
$('table tr > td:nth-child(yourColumnNumberShouldBeFiltered)').filter(function() {
return $(this).text() == "yourExactTextToFilter";
}).parent().show();
or for better performance of getting exact matches, see this link: Select element by exact match of its content

Can't overwrite CSS property with jQuery, what's wrong with my code?

I'm working on the jQuery project in The Odin Project curriculum. I've managed to create a grid inside a container that changes the color of it's boxes but I want to be able to increase the amount of boxes without popping out of the container. I think I can manage if I overwrite the css properties of the boxes with jQuery but can't figure out why it's not working.
Here's my code:
$(document).ready(function grid(boxes)
{
//Declare how many boxes in the grid.
var boxes = prompt("Choose gridsize");
//Resize boxes assigning css.
var rcsize = Math.floor(400/boxes - 3);
$('.row').css('width: ' + rcsize + 'px');
$('.row').css('height: ' + rcsize + 'px');
//Create grid.
var $row = $('<div class="row"></div>');
var $col = $('<div class="col"></div>');
for (var i = 0; i < boxes; i++) {
$row.append($col.clone());
}
for (var i = 0; i < boxes; i++) {
$("#outerbox").append($row.clone());
}
$('.col').on('hover', function() {
$(this).addClass('colon');
});
//Add functionality to navbar buttons.
$("#g").click(function() {
prompt("Choose gridsize");
});
$("#r").click(function() {
alert("sup");
});
$("#c").click(function() {
prompt("Choose color: black, red or blue");
});
});
Here's my CSS:
.body {
width: 100%;
height: 100%;
background-color: #a79696;
position: absolute;
margin: 0 0 0 0;
overflow-x: hidden;

The hover is not working on jsfiddle but it works on my index file for some reason. Thank you in advance.
jsfiddle
use css function as below
$('.row').css('width' , rcsize + 'px');
$('.row').css('height' , rcsize + 'px');
For reference check this link http://api.jquery.com/css/
you have typo in class. right here
//create grid
var $row = $('<div clas="row"></div>');
it should be
//create grid
var $row = $('<div class="row"></div>');
