Populate input boxes based on the clicked/scrolled row in table - javascript

I need your help.
With the help of existing javascript experts, I was able to create a table where a user could scoll to (using their up and down arrow keys) as well as to allow a user click on a row to select and highlight it.
Now comes time where i'd like to modify my existing function such that, whenever the user clicks on or uses their arrow keys to navigate to the selected row in the table, id like to pull the information (data) from the row and use it to populate the list of input boxes below. How could the javascript coding be modified so as to allow me to do this?

function test() {
var table = document.getElementById("mstrTable");
var thead = table.getElementsByTagName("thead")[0];

var td = e.target || e.srcElement
var row = td.parentNode;

You can write another function to populate necessary fields. Example:
function populateFields(row) {
el('firstname').value = row.cells[0].innerHTML;
el('lastname').value = row.cells[1].innerHTML;
el('age').value = row.cells[2].innerHTML;
el('total').value = row.cells[3].innerHTML;
el('discount').value = row.cells[4].innerHTML;
el('diff').value = row.cells[5].innerHTML;
}
// el() is shortcut for document.getElementById
Where you pass corresponding row to the function to get data from.

How to show temp data and delete in html table?

I have three input box and below one button
when I click that button I want input data should come into html table and sholud able to delete that record
Kindly help me out
advance thanks
I did the same with one input box. So making it for three shouldn't be an issue. You must be looking out for this code:
$("table").on("click", "tbody tr td a", function () {
$(this).closest("tr").remove();
return false;
});
You can either press Enter or click on the button to insert temp data. Okay, just heads up, as you didn't put enough code, you can do it this way:
$(function () {
$("#tempInsert").keyup(function (e) {
if (e.keyCode == 13)
insertRow();
});
$("#tempBtn").click(function () {
insertRow();
});
$("table").on("click", "tbody tr td a", function () {
$(this).closest("tr").remove();
return false;
});
});
function insertRow() {
if ($("#tempInsert").val().length > 0)
$("table tbody").append('<tr><td>' + $("#tempInsert").val() + '</td><td><a href="#">×</td></tr>');
$("#tempInsert").val("");
}

How to insert a row in an HTML table body in JavaScript

I have an HTML table with a header and a footer:
<table id="myTable">
<thead>
<tr>
<th>My Header</th>
</tr>
</thead>
<tbody>
<tr>
<td>aaaaa</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>My footer</td>
</tr>
<tfoot>
</table>
I am trying to add a row in tbody with the following:
myTable.insertRow(myTable.rows.length - 1);
but the row is added in the tfoot section.
How do I insert tbody?
If you want to add a row into the tbody, get a reference to it and call its insertRow method.
var tbodyRef = document.getElementById('myTable').getElementsByTagName('tbody')[0];
// Insert a row at the end of table
var newRow = tbodyRef.insertRow();
// Insert a cell at the end of the row
var newCell = newRow.insertCell();
// Append a text node to the cell
var newText = document.createTextNode('new row');
newCell.appendChild(newText);
<table id="myTable">
<thead>
<tr>
<th>My Header</th>
</tr>
</thead>
<tbody>
<tr>
<td>initial row</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>My Footer</td>
</tr>
</tfoot>
</table>
(old demo on JSFiddle)
You can try the following snippet using jQuery:
$(table).find('tbody').append("<tr><td>aaaa</td></tr>");
Basic approach:
This should add HTML-formatted content and show the newly added row.
var myHtmlContent = "<h3>hello</h3>"
var tableRef = document.getElementById('myTable').getElementsByTagName('tbody')[0];
var newRow = tableRef.insertRow(tableRef.rows.length);
newRow.innerHTML = myHtmlContent;
I think this script is what exactly you need
var t = document.getElementById('myTable');
var r =document.createElement('TR');
t.tBodies[0].appendChild(r)
You're close. Just add the row to the tbody instead of table:
myTbody.insertRow();
Just get a reference to tBody (myTbody) before use. Notice that you don't need to pass the last position in a table; it's automatically positioned at the end when omitting argument.
A live demo is at jsFiddle.
Add rows:
<html>
<script>
function addRow() {
var table = document.getElementById('myTable');
//var row = document.getElementById("myTable");
var x = table.insertRow(0);
var e = table.rows.length-1;
var l = table.rows[e].cells.length;
//x.innerHTML = " ";
for (var c=0, m=l; c < m; c++) {
table.rows[0].insertCell(c);
table.rows[0].cells[c].innerHTML = " ";
}
}
function addColumn() {
var table = document.getElementById('myTable');
for (var r = 0, n = table.rows.length; r < n; r++) {
table.rows[r].insertCell(0);
table.rows[r].cells[0].innerHTML = " ";
}
}
function deleteRow() {
document.getElementById("myTable").deleteRow(0);
}
function deleteColumn() {
// var row = document.getElementById("myRow");
var table = document.getElementById('myTable');
for (var r = 0, n = table.rows.length; r < n; r++) {
table.rows[r].deleteCell(0); // var table handle
}
}
</script>
<body>
<input type="button" value="row +" onClick="addRow()" border=0 style='cursor:hand'>
<input type="button" value="row -" onClick='deleteRow()' border=0 style='cursor:hand'>
<input type="button" value="column +" onClick="addColumn()" border=0 style='cursor:hand'>
<input type="button" value="column -" onClick='deleteColumn()' border=0 style='cursor:hand'>
<table id='myTable' border=1 cellpadding=0 cellspacing=0>
<tr id='myRow'>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
</body>
</html>
And cells.
let myTable = document.getElementById('myTable').getElementsByTagName('tbody')[0];
let row = myTable.insertRow();
let cell1 = row.insertCell(0);
let cell2 = row.insertCell(1);
let cell3 = row.insertCell(2);
cell1.innerHTML = 1;
cell2.innerHTML = 'JAHID';
cell3.innerHTML = 23;
row = myTable.insertRow();
cell1 = row.insertCell(0);
cell2 = row.insertCell(1);
cell3 = row.insertCell(2);
cell1.innerHTML = 2;
cell2.innerHTML = 'HOSSAIIN';
cell3.innerHTML = 50;
table {
border-collapse: collapse;
}
td, th {
border: 1px solid #000;
padding: 10px;
}
<table id="myTable">
<thead>
<tr>

<th>NAME</th>

</tr>

<tbody></tbody>
</table>
Add Column, Add Row, Delete Column, Delete Row. Simplest way
function addColumn(myTable) {
var table = document.getElementById(myTable);
var row = table.getElementsByTagName('tr');
for(i=0;i<row.length;i++){
row[i].innerHTML = row[i].innerHTML + '<td></td>';
}
}
function deleterow(tblId)
{
var table = document.getElementById(tblId);
var row = table.getElementsByTagName('tr');
if(row.length!='1'){
row[row.length - 1].outerHTML='';
}
}
function deleteColumn(tblId)
{
var allRows = document.getElementById(tblId).rows;
for (var i=0; i<allRows.length; i++) {
if (allRows[i].cells.length > 1) {
allRows[i].deleteCell(-1);
}
}
}
function myFunction(myTable) {
var table = document.getElementById(myTable);
var row = table.getElementsByTagName('tr');
var row = row[row.length-1].outerHTML;
table.innerHTML = table.innerHTML + row;
var row = table.getElementsByTagName('tr');
var row = row[row.length-1].getElementsByTagName('td');
for(i=0;i<row.length;i++){
row[i].innerHTML = '';
}
}
table, td {
border: 1px solid black;
border-collapse:collapse;
}
td {
cursor:text;
padding:10px;
}
td:empty:after{
content:"Type here...";
color:#cccccc;
}

You can also use querySelector to select the tbody, then insert a new row at the end of it.
Use append to insert Node or DOMString objects to a new cell, which will then be inserted into the new row.
var myTbody = document.querySelector("#myTable>tbody");
var newRow = myTbody.insertRow();
newRow.insertCell().append("New data");
<table id="myTable">
<thead>
<tr>
<th>My Header</th>
</tr>
</thead>
<tbody>
<tr>
<td>Data</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>My footer</td>
</tr>
</tfoot>
</table>
I have tried this, and this is working for me:
var table = document.getElementById("myTable");
var row = table.insertRow(myTable.rows.length-2);
var cell1 = row.insertCell(0);
You can use the following example:
<table id="purches">
<thead>
<tr>
<th>ID</th>
<th>Transaction Date</th>
<th>Category</th>
<th>Transaction Amount</th>
<th>Offer</th>
</tr>
</thead>
<!-- <tr th:each="person: ${list}" >
<td><li th:each="person: ${list}" th:text="|${person.description}|"></li></td>
<td><li th:each="person: ${list}" th:text="|${person.price}|"></li></td>
<td><li th:each="person: ${list}" th:text="|${person.available}|"></li></td>
<td><li th:each="person: ${list}" th:text="|${person.from}|"></li></td>
</tr>
-->
<tbody id="feedback">
</tbody>
</table>
JavaScript file:
$.ajax({
type: "POST",
contentType: "application/json",
url: "/search",
data: JSON.stringify(search),
dataType: 'json',
cache: false,
timeout: 600000,
success: function (data) {

for (var i = 0; i < data.length; i++) {
//$("#feedback").append('<tr><td>' + data[i].accountNumber + '</td><td>' + data[i].category + '</td><td>' + data[i].ssn + '</td></tr>');
$('#feedback').append('<tr><td>' + data[i].accountNumber + '</td><td>' + data[i].category + '</td><td>' + data[i].ssn + '</td><td>' + data[i].ssn + '</td><td>' + data[i].ssn + '</td></tr>');
alert(data[i].accountNumber)

Cannot extract data from TD if there is span in front

I need your help.
Because of the way IE7 chooses to ignore the TD: whitespace: nowrap, I am forced to put and use spans in front of my TD's so here's the delema. When I click on a table row that has no spans in between the td's, the coding is able to extract the data and highlight the row.
However, when I introduce a span in between my td's and click to select a single cell in the table row with the spans's I get the following error: "cells.0 is null or not an object." I know that if I click a little bit off the side of the table cell it works, but I need to be able to also click on the <TD> and <SPAN> areas and have the code work.
Since I am making a table that will have all <span></span>'s in between all the <TD>'s how can the existing coding be reformatted to accomodate the difference from <td>data</td> to <td><span>data</span></td>?
No jQuery please.

Change this line:
var row = td.parentNode;
to:
var row = (td.tagName == "DIV") ? td.parentNode.parentNode : td.parentNode;
You can look at the elemet's tag name and determine whether the user has clicked on a TD or a SPAN, then adjust select the element's parent (the TD) if you have a span.
var td = e.target || e.srcElement
alert(td.tagName)
Alternately, you can add a CSS class name to all of your SPANS and then check to see if the selected element has that class name. If it does, it's a SPAN, if it doesn't, it's a TD.
I would also suggest using a DIV, not a SPAN.

Pure Javascript: onClick executes toggle rows -- need image swap

First post, long time looker. Stack Overflow ROCKS!
Need some help. I am primarily a Business Intelligence/Data Warehouse professional. I need to use a bit of Javascript to create a collapsing row report in a report writing tool where I cannot anticipate the ability to call JQuery (Internal LAN deployment). Therefore I need pure Javascript.
The premise is I need the report to open with rows only at the Manager/District level but have the ability to open the District clusters to see the assigned Sales Reps and their contribution.
I found code that does this (quite well actually by hiding the repeating District Manager's name) but it uses text objects ("+" and "--") to render the links behind the OnClick event. I really, really, really, really need to have it show alternating images.
I tried simply modifying these two sections but the code to render the image in the first block does not match the code for the second block, this causes the ternary operation to fail and the images to do not alternate as expected.
lnk.innerHTML =(lnk.innerHTML == "+")?"--":"+";
var link ='+';
The code below contains the working code with text for onClick action and below a simple onClick that switches the images. Essentially I need the Folder Icons to be in the first cell of the Manager/District grids. I forced the working collapse code into the main Javascript block just to save space.
Any help, insight, guidance, electric cattle prod shocks (ouch) would be appreciated.
Thanks in advance.
UPDATE: created a CodePen for this to make it easier to see what works right now:
