How to insert a row in an HTML table body in JavaScript
(13 answers)
Closed 1 year ago.
I recently started to code and I'm trying to build an expense application using HTML, CSS, and JavaScript. I'm creating a replica of this photo
Here is my HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<link rel="stylesheet" type="text/css" href="css/style.css">
<title>Expense Tracker</title>
</head>
<body>
<h1>Expense Tracker</h1>
<div id="myDiv">
<label for="name">Name:</label>
<input type="text" name="myInput" id="myInput" placeholder="Name of expense" size="50"><br><br>
<label for="date">Date:</label>
<input type="date" id="myDate" name="myDate">
<label for="amount">Amount:</label>
<input type="text" name="myAmount" id="myAmount" placeholder="Dollar amount ($)"><br><br>
<span onclick="addRow()" class="addBtn">Add Expense</span>
</div>
<br>
<table id="myTable">
<tr>
<th>Name</th>
<th>Date</th>
<th>Amount</th>
<th>Delete</th>
</tr>
<tr>
<td>McDonald's</td>
<td>6/22/2017</td>
<td>$12.00</td>
<td><input type="button" value="Delete" onclick="deleteRow(this)"></td>
</tr>
</table>
<script src="script.js"></script>
</body>
</html>
Here is my JavaScript, so far:
function deleteRow(r) {
var i = r.parentNode.parentNode.rowIndex;
document.getElementById("myTable").deleteRow(i);
}
How do I add additional rows using JavaScript? I can delete rows, using the JavaScript code above, but I am having a hard time figuring out how to add new elements.
You will need to do this via DOM manipulation.
Something like this should work...
<button type="button" onclick="myFunction()">New row</button>
function myFunction() {
var table = document.getElementById("myTable");
var row = table.insertRow(0);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
cell1.innerHTML = "NEW CELL1";
cell2.innerHTML = "NEW CELL2";
}

What is DOM Event delegation?

Closed 4 years ago.
I have a table in which an input control calls a java script event
oninput="this.value=this.value.replace(/[^0-9]/g,'');
By Clicking on Add Row new Row is being inserted but i want to call this event on new row as well . This event is to stop except positive whole numbers
using the following code.

Try the following syntax to add event handler to newly created element:
element1.oninput = function() {
this.value = this.value.replace(/[^0-9]/g,'');
}

First let me start by saying I am very new to javascript. I am currently studying the subject as part of a course I am doing.
I have an assignment that requires me to put together image slices in a table built by javascript and place it in a on a HTML page.
I have had success with all of this except when i attempt to resize the table and div section with CSS the images separate leaving gaps in the image. Is there anyone out there who can see why i am getting this issue? Im pulling my hair out.
here is my code.

Any help here would be great thanks.
I am trying to get my variable I have saved to display on a table I have created on another page. I get the information from the user from a form, and have a button that is clicked and fires off to save the values into variables.

Local Storage is your best bet.
// Save data to the current local store
localStorage.setItem("username", "John");
// Access some stored data
alert( "username = " + localStorage.getItem("username"));

I am a beginner and I am trying to write a simple program that calculates a late fee based on a given previous invoice amount/payments. I am stumped in the early portion of this project and basically where I am trying to start is by taking the user inputted values and having them show in my table below, for some reason I cannot figure this out. You can check out what I have so far here: http://176.32.230.9/testingnicoledelarosa.com/
This is the code I have thus far:
<!doctype html>
<html>
<head>
<title>Late Fee Calculator</title>
<meta charset="utf-8" />
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<link rel="stylesheet" type="text/css" href="style.css">
<script>
function addRow() {
var table= document.getElementByID("results");
var row= document.createElement("tr");
var td1= document.createElement("td");
var td2= document.createElement("td");
var td3= document.createElement("td");
td1.innerHTML = document.getElementByID("invoiceAmount").value;
td2.innerHTML = document.getElementByID("previousBalance").value;
td3.innerHTML = document.getElementByID("paymentAdjustments").value;
row.appendChild(td1);
row.appendChild(td2);
row.appendChild(td3);
table.children[0].appendChild(row);
}
</script>
</head>
<body>
<div>
<form>
Invoice Amount:<br>
<input type="number" id="invoiceAmount">
<br>
<br>
Previous Balance:<br>
<input type="number" id="previousBalance">
<br>
<br>
Payments/Adjustments:<br>
<input type="number" id="paymentAdjustments">
<br>
<br>
<input type="submit" value="Submit" onclick="addRow()">
</form>
</div>
<br>
<div>
<table border="1" id="results">
<tr>
<th>Total Invoice Amount</th>
<td>data</td>
</tr>
<tr>
<th>Previous Balance</th>
<td>data</td>
</tr>
<tr>
<th>Payments/Adjustments</th>
<td>data</td>
</tr>
<tr>
<th>Late Fee</th>

<tr>
<th>Balance (Amount Due)</th>

</table>
</div>

Well, there are two reasons.
First, the "document.getElementByID" calls should be "document.getElementById" (lower-case d).
But, to prevent your form from actually submitting and reloading the page (and in your case clearing out the data in the table), you could add a 'return false;' at the end of your addRow() function. So it would look like this:
function addRow() {
var table= document.getElementById("results");
var row= document.createElement("tr");
var td1= document.createElement("td");
var td2= document.createElement("td");
var td3= document.createElement("td");
td1.innerHTML = document.getElementById("invoiceAmount").value;
td2.innerHTML = document.getElementById("previousBalance").value;
td3.innerHTML = document.getElementById("paymentAdjustments").value;
row.appendChild(td1);
row.appendChild(td2);
row.appendChild(td3);
table.children[0].appendChild(row);
return false;
}
And your input tag would then look like this:
<input type="submit" value="Submit" onclick="return addRow();">
Hope that helps!
I am working on a history search function.
I have managed to get a working code to save the value from the textbox but I do not know how to load them into a listbox.
I want a listbox with clickable items so that I can click on a previous search value and load that value as I do from the textbox.
Here is my code:
<!doctype html>
<html lang="en">
<head>
<title>Test</title>
<meta charset="utf-8>
<link rel="stylesheet" type="text/css" href="test.css">
<script src="jquery.js"></script>
<script src="j.js"></script>
</head>
<body>
<center>
<table>
<tr>
<td style="text-align: center">
<font size="22">Sök order</font>
</td>
</tr>
<tr>
<td>
<form action="test.php" method="post">
<input style="font-size: 44pt; text-align: center" size="9" type="text" name="txtSearch" id="txtSearch"/>
<input type="submit" id="submit" value="submit">
</form>
</td>
</tr>
</table>
</center>
</body>
</html>
And the j.js that handles the local storage function.
$(function () {
$("#submit").click(function () {
var txtSearch = $("#txtSearch").val();
localStorage.setItem('searchvalue',txtSearch);
});
});
And last my test.php that handles the post search request
<?php
$txtSearch = $_REQUEST['txtSearch'];
header('Location: '.'https://mywebsite.com/se/editor/order_info.php?webshop=23946&ordernr='.$txtSearch);
?>
How can I achieve this?
Thank you.
by js, you can
window.location = "https://mywebsite.com/se/editor/order_info.php?webshop=23946&ordernr="+localStorage.getItem('searchvalue');
to save in listbox or any other
document.getElementById("id").value=localStorage.getItem('searchvalue');
to save in array
var a = [];
a[0]=localStorage.getItem('searchvalue');
