How to sort tables in HTML by number
By the way, I know there are questions like this on StackOverflow but none address my issue so please don't close my question with a response of a post with a similar title, but nothing to do with my issue
Context
I am creating a web application for a non-profit little league team. It simply displays the player info on the live stream when you select them in the web app. My client wanted it so it displays the players in order by their batting number, so I did this with the sorttable.js or whatever it is called but I'm having sorting issues
Issues
For example if this is the table
Name
Batting Order
Player 1
1
Player 2
10
Player 3
2
10 would go before 2 because it has a 1.
What I've tried
I've tried making 1 to 01 and 2 to 02 which did work. But I can't use this because the system to calculate whose next gets confused with 02.
What I want
I want to be able to sort my HTML table with javascript by number in the correct order without having 10 be before 2
Code
In case it's needed this is the code
<table class='table table-hover table-dark table-bordered sortable'>
<thead>
<tr>
<!-- <th>Picture</th> -->
<th>Name</th>
<th>Number</th>
<th>Batting Order</th>
<th>Action</th>
</tr>
</thead>
<tbody id="homes">
</tbody>

Something like this would do the job (without using any libraries):
const tb=document.getElementById("homes"),
trs=[...tb.children];
document.body.onclick=ev=>{
let col= ev.target.dataset?.col;
if(col){
trs.sort((a,b)=>a.children[col].textContent-b.children[col].textContent);
trs.forEach(tr=>tb.append(tr));
}
}

According to the documentation you simply need to add the "sortable" class to the table and add some css for their default style scheme like below. One step in troubleshooting is to remove all of the "fluff" and strip down your solution to the bare minimum. Below, for example, I've removed all of the other classes from the table as a test... it seems to be working fine and sorting appears to be giving the expected result.
To further debug your solution, add back those classes one at a time and see if/when the table stops working.
/* Sortable tables */
table.sortable thead {
background-color: #eee;
color: #666666;
font-weight: bold;
cursor: default;
}
<table class='sortable'>

According to the documentation again, if your table is created dynamically at some point after page load you can use the .makeSortable(); function to make it sortable like this.
// populate the table with data before unitializing it.
let playerstable = document.getElementById("playerstable");
sorttable.makeSortable(playerstable);

I am making a shopping list in my web page where I add the items which I store in localStorage.The items are displayed in a table.The problem is that for each new item added it is showing also the data previously stored again.
My html is:
<form class="market">
<label>Nume produs</label>
<input type="text" id="np">
<label>Cantitate</label>
<input type="text" id="cp">
<input type="button" onclick="addItem();" id="adauga" value="Adaugă" />
</form>
<table>
<tbody id="shopping">
<tr>
<th>Nr.</th>
<th>Name</th>
<th>Quantity</th>
</tr>
And this is the function called on every button click
class Produs{
constructor(id, nume, cantitate){
this.id = id;
this.nume = nume;
this.cantitate = cantitate;
}
}
function addItem(){
let nume = document.getElementById("np").value;
let cantitate = document.getElementById("cp").value;
let produse = localStorage.getItem('produse');
if(produse == null){
produse = [];
}
else{
produse = JSON.parse(produse);
}
produse = produse.map((p) => {
return new Produs(p.id, p.nume, p.cantitate);
});
let lastId = localStorage.getItem('lastId');
if(lastId == null)
{
lastId=1;
}
else{
lastId = JSON.parse(lastId);
}
let id = lastId;
produse.push(new Produs(id, nume, cantitate));
localStorage.setItem('produse',JSON.stringify(produse));
localStorage.setItem('lastId',JSON.stringify(lastId+1));
var jsonData = JSON.parse(localStorage.getItem('produse'));
console.log(jsonData);
for(var i=0; i<jsonData.length; i++)
{
document.getElementById("shopping").innerHTML +="<tr><td>"+jsonData[i].id +"</td><td>" + jsonData[i].nume +"</td><td>"+jsonData[i].cantitate+"</td></tr>";
}
}

$scope.getSelectedObject = function(object) {

return "";
};
$scope.selectObject = function(object, index){
$scope.selectedObject = object;
}
$scope.finalList = [];
$scope.theListB = [];
$scope.counter = 0;
$scope.priceOfProducts = 0;
$scope.buyIt = function(){
if ($scope.selectedProduct.unitsInStore>0){
$scope.selectedProduct.unitsInStore--;
$scope.theListB.push($scope.selectedProduct);
$scope.priceOfProducts += $scope.selectedProduct.pricePerUnit;
}else{
alert("The product ID:" + $scope.selectedProduct.productId +"\n" +
"With the name:" + $scope.selectedProduct.productName + "\n"
+"Is out of stock!");
}
$scope.showList();
}
$scope.showList=function(){
$scope.finalList = [];
angular.forEach($scope.theListB, function(productFromListB, key){
var go = true;
angular.forEach($scope.allSProducts, function(productFromStores, key){
if(productFromListB.productId == productFromStores.productId){
// if(go){
$scope.object.product = productFromListB;
$scope.object.unitsOutStore = productFromStores.unitsInStore - productFromListB.unitsInStore;
$scope.object.maxNumber = productFromStores.unitsInStore;
$scope.finalList.push($scope.object);
go = false;
// }
}
});
});
}
so in the end, i got the function $scope.showList()
there i have theListB filed with my 10 or more objects
that data i modify and add to finalList with this line:
$scope.finalList.push($scope.object);
but on the jsp page, it only shows the last added object in the table row
in ng-repeat...
any sugestions?

I would like to highlight a few things for this code:
In your code, the loop starts from 0, as table has first row as header row, it will not contain any "tr" elements. Hence your function is not working.
If we start loop from 1, you need to go through the input element to search the value. Existing approach wont work.
In case of loop starting from 1, your fullname variable will look like this:
May be you will have to modify your comparison logic by fetching the value of input fields.
Ok, here is a working version, but your algorithm is not perfect.
You can debug and fix the logic errors:
First problem:
onKeyUp="javascript:doSearch();"
JSFiddle
There was many semantical errors compare with yours, still not perfect:
(lass then 3 letters problem, and cases when it finds something)
If you type "course", it finds, but still keeps all visible (you have to fix it, it's easy.)
If you type less then 3 letters, do nothing, don't hide all.
function doSearch() {
var q = document.getElementById("q");
var v = q.value.toLowerCase();
var rows = document.getElementsByTagName("tr");
var on = 0;
for (var i = 0; i < rows.length; i++) {
var fullname = rows[i].getElementsByTagName("td");
if (fullname.length > 0) {
fullname = fullname[0].innerHTML.toLowerCase();
if (fullname) {
if (v.length == 0 || (v.length < 3 && fullname.indexOf(v) == 0) || (v.length >= 3 && fullname.indexOf(v) > -1)) {
rows[i].style.display = "";
on++;
} else {
rows[i].style.display = "none";
}
}
}
}
}
Is your html the way you wanted? You seem to want to create a table with rows, and then filter those rows based on the users input. The way your html is now, there is only one row.
After you fix that, I would recommend using jquery. Here is a fiddle to get you started: http://jsfiddle.net/SuRWn/11/
$(function () {
var q = $('#q'),
boxes = $('td input');
$('#q').on('keyup', function (e) {
var qterm = q.val();
if (qterm.length < 3) {
boxes.show();
} else {
boxes.each(function(i,o) {
var box = $(this);
box.toggle(box.val().indexOf(qterm) > -1);
});
}
});
});
edit: note that the fiddle is filtering your input boxes and now the rows (since there are no rows to filter)
What is the javascipt code that will edit a text on double click. The process is I have a text and if I double click it, a text box will appear, and if I press enter the word will change depends on what you've type.
Sample
This is sample text. $nbsp;$nbsp; --> if I double click it a textbox will appear.
<input type="text" value="This is sample text." name="" />
Sorry for asking this. I am a newbie in javascript
Here is a great example.
I'm going to paste in the script from that example so that it's preserved in case that link goes away, but you should follow the link -- the article does a great job of breaking the script down line by line and explaining what it does. A great learning opportunity for javascript.
var editing = false;
if (document.getElementById && document.createElement) {
var butt = document.createElement('BUTTON');
var buttext = document.createTextNode('Ready!');
butt.appendChild(buttext);
butt.onclick = saveEdit;
}
function catchIt(e) {
if (editing) return;
if (!document.getElementById || !document.createElement) return;
if (!e) var obj = window.event.srcElement;
else var obj = e.target;
while (obj.nodeType != 1) {
obj = obj.parentNode;
}
if (obj.tagName == 'TEXTAREA' || obj.tagName == 'A') return;
while (obj.nodeName != 'P' && obj.nodeName != 'HTML') {
obj = obj.parentNode;
}
if (obj.nodeName == 'HTML') return;
var x = obj.innerHTML;
var y = document.createElement('TEXTAREA');
var z = obj.parentNode;
z.insertBefore(y,obj);
z.insertBefore(butt,obj);
z.removeChild(obj);
y.value = x;
y.focus();
editing = true;
}
function saveEdit() {
var area = document.getElementsByTagName('TEXTAREA')[0];
var y = document.createElement('P');
var z = area.parentNode;
y.innerHTML = area.value;
z.insertBefore(y,area);
z.removeChild(area);
z.removeChild(document.getElementsByTagName('button')[0]);
editing = false;
}
document.onclick = catchIt;
I wanted to know how it works as I have seen it on many websites. And I build it using jQuery
$(document).dblclick(function(event) {
var id = event.target.id; //id
// var id = $(this).attr('id');
if (id == "") {
console.log("nope");
} else {
id = "#" + id + "";
console.log(typeof(id)); //concatenated with #
text = $(id).text().trim();
console.log(text); //asscociated text
$(id).html('<textarea name="" id="tex" cols="10" rows="1" onkeypress="myFunction(event)">' + text + '</textarea>');
// alert(id);
}
})
function myFunction(event) {
var x = event.code;
var id = $(this).attr('id');
parentId = event.path[1].id;
parentId = "#" + parentId + "";
if (x == 'Enter') {
name = $('#tex').val();
$(parentId).text(name);
}
}
