Newbie here...
How do I add a function on which I can delete a specific table row? In the last hours.. All I can do is making an output results that keeps deleting all the rows(not just 1 row.. Its like clearing all the inputs in the table) by using table.deleteRow() whether it is by creating html buttons and creating a delete functions.
Is there a way also I can delete the specific row by selecting it in a highlight function?
Thanks
var entryButton = document.getElementById('inputButton')
const tbodyEl = document.querySelector("tbody");
var row = 1;
entryButton.addEventListener('click', tableDisplay);
function tableDisplay (e) {
e.preventDefault()
var name = document.getElementById('inputName').value;
var amount = document.getElementById('inputAmount').value;
var date = document.getElementById('inputDate').value;
var remarks = document.getElementById('inputRemarks').value;
if(!name || !amount || !date || !remarks) {
alert("Please fill all the blanks")
return;
}
var table = document.getElementById('displayTable');
var newRow = table.insertRow(row);
var cell1 = newRow.insertCell(0);
var cell2 = newRow.insertCell(1);
var cell3 = newRow.insertCell(2);
var cell4 = newRow.insertCell(3);
cell1.innerHTML= name
cell2.innerHTML= date
cell3.innerHTML= amount
cell4.innerHTML= remarks
selectedRow()
deselectedRow()
row++;
}
//highlighting the row
function selectedRow(){
var table = document.getElementById('displayTable');
for (var i=0;i < table.rows.length;i++){
table.rows[i].onclick= function () {
if(!this.selected){
deselectedRow();
this.origColor=this.style.backgroundColor;
this.style.backgroundColor='#90EE90';
this.selected = true;
}
else{
this.style.backgroundColor=this.origColor;
this.selected = false;
}
}
}
}
function deselectedRow(){
var table = document.getElementById('displayTable');
for (var i=0;i < table.rows.length;i++){
var row = table.rows[i];
row.style.backgroundColor=this.origColor;
row.selected = false;
}

</html>You can use the following code, i've changed a bit yours by setting the class instead of background color on selected row, then deselectedRow was useless in your case.
So what's happening, on click i add to the row selected-row class and if you click it again that class will be remove, then on "deleteSelection" button i've added a click handler which execute the deleteSelections function, which will delete all the rows with the selected-row class.
Here is the code:
var entryButton = document.getElementById('inputButton')
const tbodyEl = document.querySelector("tbody");
var row = 1;
entryButton.addEventListener('click', tableDisplay);
function tableDisplay(e) {
e.preventDefault()
var name = document.getElementById('inputName').value;
var amount = document.getElementById('inputAmount').value;
var date = document.getElementById('inputDate').value;
var remarks = document.getElementById('inputRemarks').value;
if (!name || !amount || !date || !remarks) {
alert("Please fill all the blanks")
return;
}
var table = document.getElementById('displayTable');
var newRow = table.insertRow(row);
var cell1 = newRow.insertCell(0);
var cell2 = newRow.insertCell(1);
var cell3 = newRow.insertCell(2);
var cell4 = newRow.insertCell(3);
cell1.innerHTML = name
cell2.innerHTML = date
cell3.innerHTML = amount
cell4.innerHTML = remarks
selectedRow()
row++;
}
//highlighting the row
document.getElementById('deleteSelection').addEventListener('click', deleteSelections);
function deleteSelections() {
let selectedRows = document.getElementsByClassName("selected-row ");
while(selectedRows.length > 0){
selectedRows[0].parentNode.removeChild(selectedRows[0]);
}
}
function selectedRow() {
var table = document.getElementById('displayTable');
for (var i = 0; i < table.rows.length; i++) {
if (i > 0) {
table.rows[i].onclick = function() {
if (!this.selected) {
this.classList.add('selected-row')
this.selected = true;
} else {
this.classList.remove('selected-row')
this.selected = false;
}
}
}
}
}.selected-row {
background-color: #90EE90;
