Delete crossed and go to line below when clicking button - javascript

Every time you click on "Add grade" button, I want the next things that will appear to be in the line below that one.
And when I click on the button "-", I want everything in that line to be erased.
delete
nextline
Just try the code below and you'll see what I'm talking about.
input[type="number"]{
color : transparent;
text-shadow : 0 0 0 #000;
}
input[type="number"]:focus{
outline : none;
}
</style>
<button type="button" id="dugme1" onclick="javascript:dodajocenu();"> Add grade</button>
<br><br>
<div id="stranica">
</div>
<script>
var ocena = 0;
function removeElement(obrisi) {
var dugme = obrisi.target;
var input = dugme.previousSibling;
var brisi = dugme.parentElement;
brisi.removeChild(dugme);
brisi.removeChild(input);
}
function dodajocenu() {
ocena++;
//create textbox
var input = document.createElement('input');
input.type = "number";
input.setAttribute("max",5);
input.setAttribute("min",1);
var myParent = document.body;
//Create array of options to be added
var array = ["Volvo","Saab","Mercades","Audi"];
//Create and append select list
var selectList = document.createElement('select');
selectList.id = "mySelect";
myParent.appendChild(selectList);
//Create and append the options
for (var i = 0; i < array.length; i++) {
var option = document.createElement('option');
option.value = array[i];
option.text = array[i];
selectList.appendChild(option);
}
//create remove button
var remove = document.createElement('button');
remove.onclick = function(obrisiocenu) {
removeElement(obrisiocenu);
}
remove.setAttribute("type", "dugme");
remove.innerHTML = "-";
stranica.appendChild(input);
stranica.appendChild(selectList);
stranica.appendChild(remove);
}
</script>```

Try to run the following code, let me know if this is what you want to do.
var ocena = 0;
var stranica = document.querySelector("#stranica")
function removeElement(obrisi) {
var dugme = obrisi.target;
stranica.removeChild(dugme.parentElement)
}
function dodajocenu() {
ocena++;
//create textbox
var input = document.createElement('input');
input.type = "number";
input.setAttribute("max",5);
input.setAttribute("min",1);
var myParent = document.body;
//Create array of options to be added
var array = ["Volvo","Saab","Mercades","Audi"];
//Create and append select list
var selectList = document.createElement('select');
selectList.id = "mySelect";
myParent.appendChild(selectList);
//Create and append the options
for (var i = 0; i < array.length; i++) {
var option = document.createElement('option');
option.value = array[i];
option.text = array[i];
selectList.appendChild(option);
}
//create remove button
var remove = document.createElement('button');
remove.onclick = function(obrisiocenu) {
removeElement(obrisiocenu);
}
remove.setAttribute("type", "dugme");
remove.innerHTML = "-";
var item = document.createElement('div')
item.classList.add("item")
item.appendChild(input);
item.appendChild(selectList);
item.appendChild(remove);
stranica.appendChild(item)
}
input[type="number"]{
color : transparent;
text-shadow : 0 0 0 #000;
}
input[type="number"]:focus{

Why doesn't the selected value of my dynamically created select tag change?

Based on the length of the array fetched from the server as response, I am dynamically creating table rows, where each row will have one record. This is my code:
var array = ["I","I-S","II","III","IV","IV-S","V","VI","VI-S"];
const arr=JSON.parse(response);
for(var i=0;i<arr.length;i++){
var row=table.insertRow(table.rows.length);
var cell=row.insertCell(0);
var cell1=row.insertCell(1);
var cell2=row.insertCell(2);
var cell3=row.insertCell(3);
var input = document.createElement("input");
input.type = "text";
input.className="books";
input.value=arr[i][0];
input.style.textAlign="center";
var input1 = document.createElement("input");
input1.type = "text";
input1.className="pages";
input1.value=arr[i][1];
input1.style.textAlign="center";
var input2 = document.createElement("select");
input2.className="types";
input2.style.textAlign="center";
for (var i = 0; i < array.length; i++) {
var option = document.createElement("option");
option.value = array[i];
option.text = array[i];
input2.appendChild(option);
}
$(".types option[value*='"+arr[i][2] +"']").attr('selected', 'selected');
//The selected value should be the one that is in arr[i][2]
var input3 = document.createElement("input");
input3.type = "text";
input3.className="nos";
input3.value=arr[i][3];
input3.style.textAlign="center";
cell.appendChild(input);
cell1.appendChild(input1);
cell2.appendChild(input2);
cell3.appendChild(input3);
}
When I execute the above script, all the <select> tags have VI-S as the selected value. But it should be the one that is in arr[i][2]. How do I change the selected value?

How to change value of parent element to an element

I am trying to change the css property of the "node"-class by clicking on the div inside of it which got the class "expand".
When I click on the "expand" div inside the "note", I want to go to parent "note" for changing it size:
var text = document.getElementById("text");
var add = document.getElementById("add");
var notespace = document.getElementById("notespace");
var expand = document.getElementsByClassName("expand");
var notes = document.getElementsByClassName("note");
add.addEventListener("click", function () {
var textValue = text.value;
var p = document.createElement("p");
p.innerHTML = "<div class='note'>" + textValue +
"<br/><br/><div class='expand'> Expand </div></div>";
notespace.appendChild(p);
text.value = "";
for (var i = 0; i < expand.length; i++) {
expand[i].addEventListener("click", function () {
notes[i].style.size = "3000px";
})
}
})
You have to re-get the values of expand and notes, because after you add them to your html, the two variables expand and notes, dont know yet that you have added them and they don't contain them. ( you also have to removee the eventlistner otherwise you're gonna get a bugg at approximately twelve notes added :D because you will have too many eventListners on each element
var text = document.getElementById("text");
var add = document.getElementById("add");
var notespace = document.getElementById("notespace");
var expand = document.getElementsByClassName("expand");
var notes = document.getElementsByClassName("note");
add.addEventListener("click", function(){
var textValue = text.value;
var p = document.createElement("p");
p.innerHTML = "<div class='note'>" + textValue + "<br/><br/><div class='expand'> Expand </div></div>";
notespace.appendChild(p);
text.value = "";
for( var i = 0; i < expand.length; i++){
const note = notes[i];
expand[i].addEventListener("click", function() {
note.style.size = "3000px";
note.style.backgroundColor = "red";
});
}
})
#notespace {
width: 100%,
height: 100%,
background: grey,
}
<button type="button" id="add">add</button>
<input id="text"/>
<div id="notespace">
</div>
You can use the parentNode attribute :
for( var i = 0; i < expand.length; i++){
expand[i].addEventListener("click", function(){
this.parentNode.style.size = "3000px";
})
}
Or the closest() method :
for( var i = 0; i < expand.length; i++){
expand[i].addEventListener("click", function(){
this.closest(".note").style.size = "3000px";
})
}
Note that closest() is not supported on IE.

create `select` element using javascript

I have an html table that I am creating dynamically its populating everything Accept select element I tried all the methods but its not working please have a look.
My complete code for table:-
function getreferData(dataArray) {
let selectArray = ["Intvw Scheduled", "Selected", "Rejected", "On Hold"];
var ray = dataArray.splice(0, 1)
let table = document.getElementById('thead1');
var tableHeaderRow = document.createElement("tr");
table.appendChild(tableHeaderRow);
for (i = 0; i < ray[0].length; i++) {
var tableHeader = document.createElement("th");
tableHeaderRow.appendChild(tableHeader);
tableHeader.innerHTML = ray[0][i];
}
let tbody = document.getElementById('perf');
for (var i = 0; i < dataArray.length; i++) {
let row = document.createElement("tr")
for (var j = 0; j < dataArray[i].length; j++) {
if (j == 4) {
let col = document.createElement("td")
var a = document.createElement("a");
a.setAttribute("class", "light-blue-text text-light-blue")
a.href = dataArray[i][j];
var node = document.createTextNode("Click here")
a.appendChild(node)
col.appendChild(a)
row.appendChild(col)
} else if (j == 6) {
var col = document.createElement("td");
col.appendChild(createDropdown("status-" + dataArray[i]));
var lbl = document.createElement("label");
lbl.setAttribute("for", "status-" + dataArray[i]);
col.appendChild(lbl)
row.appendChild(col)
} else if (j == 7) {
let col = document.createElement("td")
var a2 = document.createElement("a");
a2.setAttribute("class", "btn blue-grey darken-3 waves-effect waves-light");
a2.setAttribute("onclick", "editrefrecord(\"" + dataArray[i] + "\")");
a2.setAttribute("style", "color: white");
var node2 = document.createTextNode("UPDATE");
a2.appendChild(node2);
col.appendChild(a2);
row.appendChild(col)
} else {
let col = document.createElement("td")
col.innerText = dataArray[i][j]
row.appendChild(col)
}
}
tbody.appendChild(row);
}
function createDropdown(id) {
//create a radio button
var fragment = document.createDocumentFragment();
var select = document.createElement('select');
select.setAttribute("id", id);
selectArray.forEach(function (r) {
select.options.add(new Option(r, r));
});
fragment.appendChild(select);
return fragment;
}
}
The only thing you would like to focus is:-
let selectArray = ["Intvw Scheduled", "Selected", "Rejected", "On Hold"];
else if (j == 6) {
var col = document.createElement("td");
col.appendChild(createDropdown("status-" + dataArray[i]));
var lbl = document.createElement("label");
lbl.setAttribute("for", "status-" + dataArray[i]);
col.appendChild(lbl)
row.appendChild(col)
}
and the function to create select element :-
function createDropdown(id) {
//create a radio button
var fragment = document.createDocumentFragment();
var select = document.createElement('select');
select.setAttribute("id", id);
selectArray.forEach(function (r) {
select.options.add(new Option(r, r));
});
fragment.appendChild(select);
return fragment;
}
Currently My Html table looks like this and If you will see Status is not populating select option:-
The Inspect Element shows its created but its invisible:-
You Missed adding options
let selectArray = ["Intvw Scheduled", "Selected", "Rejected", "On Hold"];
var selectList = document.createElement("select");
selectList.id = "mySelect";
myParent.appendChild(selectList);
//Create and append the options
for (var i = 0; i < selectArray.length; i++) {
var option = document.createElement("option");
option.value = selectArray[i];
option.text = selectArray[i];
selectList.appendChild(option);
}

Removing the corresponding textbox of the anchor tag

I have created a simple application in javascript. The application is that a value is selected from a dropdown list and if the button next to it is clicked then the specified number of texboxes selected in the dropdown are added to the DOM with a a to their right sides.
Here's the HTML:
<form>
<select style="width: 250px;" id="numMembers" <!--onchange="addMembers();" -->>
<option value="0">Add More Members...</option>
<script>
for (var i = 1; i <= 10; i++) {
document.write('<option value=' + i + '>' + i + '</option>');
};
</script>
</select>
<button onclick="addMembers();" type="button">Add</button>
<div style="margin-top: 10px; border: 1px solid #eee; padding: 10px;">
<input type="text" />
<br/>
<input type="text" />
<br/>
<input type="text" />
<br/>
</div>
<div id="extras"></div>
</form>
And here's the script:
function addMembers() {
var num = document.getElementById("numMembers").options["selectedIndex"];
for (var i = 0; i < num; i++) {
var lineBreak = document.createElement("br")
var txtInput = document.createElement("input");
txtInput.type = "text";
txtInput.style.display = "inline";
var removeHref = document.createElement("a");
removeHref.href = "#";
removeHref.innerHTML = "Remove(x)";
removeHref.style.marginLeft = "5px";
removeHref.style.display = "inline";
removeHref.onclick = function () {
document.removeChild(this);
};
document.getElementById("extras").appendChild(lineBreak);
document.getElementById("extras").appendChild(txtInput);
document.getElementById("extras").appendChild(removeHref);
}
}
How can I remove the textbox on the left of the anchor tag which is when clicked. For example:
[XXXXXXX] Remove(x)
[XXXXXXX] Remove(x)
If the last "Remove(x)" is clicked then the last textbox should be removed hence the one to the left of it.
How can I do it?
Note: No JQuery solutions please! I could do that even myself :P.
You can pass the id on anchorTag and can pass same id with some addition for input text, like
If you pass the id input1 for a then use the id input1Text for relative text box,
So you when you click on particular link, you will get a with input1 and get relative input text with 'input1Text'.
This would be apply for input2, input3, ... Something like this.
DEMO
function addMembers() {
var num = document.getElementById("numMembers").options["selectedIndex"];
for (var i = 0; i < num; i++) {
var lineBreak = document.createElement("br")
var txtInput = document.createElement("input");
txtInput.type = "text";
txtInput.id = "input"+i+"Text"; //give the id with Text
txtInput.style.display = "inline";
var removeHref = document.createElement("a");
removeHref.href = "#";
removeHref.innerHTML = "Remove(x)";
removeHref.style.marginLeft = "5px";
removeHref.style.display = "inline";
//when you click on this link you will get relative textbox by "input"+i+"Text";
removeHref.id = "input"+i;
removeHref.onclick = function () {
var removeNodeText = document.getElementById(this.id+"Text");
removeNodeText.parentNode.removeChild(removeNodeText);
var removeNodeLink = document.getElementById(this.id);
removeNodeLink.parentNode.removeChild(removeNodeLink);
};
document.getElementById("extras").appendChild(lineBreak);
document.getElementById("extras").appendChild(txtInput);
document.getElementById("extras").appendChild(removeHref);
}
}
Try This
function addMembers() {
var num = document.getElementById("numMembers").options["selectedIndex"];
for (var i = 0; i < num; i++) {
var lineBreak = document.createElement("br")
var txtInput = document.createElement("input");
txtInput.id = "text_"+i;
txtInput.type = "text";
txtInput.style.display = "inline";
var removeHref = document.createElement("a");
removeHref.href = "#";
removeHref.id = "href_"+i;
removeHref.innerHTML = "Remove(x)";
removeHref.style.marginLeft = "5px";
removeHref.style.display = "inline";
removeHref.onclick = function(){
var id= this.id.split('_')[1];
console.log(id)
document.getElementById("extras").removeChild(document.getElementById('text_'+id));
document.getElementById("extras").removeChild(this);
}
document.getElementById("extras").appendChild(lineBreak);
document.getElementById("extras").appendChild(txtInput);
document.getElementById("extras").appendChild(removeHref);
}
}
