how to find out the cell values.i have tried the following code but it showing entire TD row
tbl.rows[i].cells[j].innerHTML);
alert(tbl.rows[i].cells[j].innerHTML);
Kindly help in finding the value.. thanks.
Table cells don't have values, only input elements do. You need to access the <input> element within the table cell.
Use:
tbl.rows[i].cells[j].getElementsByTagName("input")[0].value

I am looping through a grids datasource and when it gets to ToFactory not being empty I need to add a div into its td cell. Below is the code that I am using to get the td at index 18 of its row
var data = this.dataSource.view();
for(i=0;i<data.length;i++){
var dataItem = data[i];
var tr = $("#QuickEntryGrid").find("[data-uid='" + dataItem.uid + "']");
if(dataItem.ToFactory != ""){
let me = tr.find('td')[18];
me.innerHtml = "<div class='abc'>1234</div>"; // Doesn't work
console.log(me);
}
}
the variable me is
<td class role='gridcell'></td>
and what I would like to put in the td is
<div class='abc'>123</div>
and me should look like this
<td class role='gridcell'><div class='abc'>123</div></td>
but its not happening,
any idea's on why I am not getting this working? I have also tried
me.append("<div class='abc'>123</div>");
I have a table which looks essentially like this
<!DOCTYPE html>
<html lang="en">
<body>
<table class="ui table" id="items">
<tbody>
<tr data-toggle="fieldset-entry">
<td><input id="items-0-quantity" name="items-0-quantity" type="text" value=""></td>
<td><input id="items-0-description" name="items-0-description" type="text" value=""></td>
</tr>
</body>
</html>
Using javascript, I'd like to have a button which adds a new row to the table, and I'd like the inputs in that new row to have id="items-1-xxx", and name="items-1-xxx, i.e. where there's a 0 in the original row I'd like a 1 in the new row.
I can make a new table row by cloning the old one, but I have not figured out how to modify the name and id attributes of the input.
Here's a sketch of what I've tried:
function cloneRow() {
var table = document.getElementById("items");
var original_row = table.rows[table.rows.length - 1];
var new_row = original_row.cloneNode(true);
// We have a new row and now we need to modify it as
// described in the question. The only way I've found
// is to grab the inner HTML:
var cell_contents = original_row.cells[0].innerHTML;
// Now we could do a bunch of string parsing and manipulations
// to increment the 0 to a 1 and stuff the modified HTML into
// new_row, but it seems there must be a better way.
// Finally insert the new row into the table.
original_row.parentNode.insertBefore(new_row, original_row.nextSibling);
}
What is the right way to update the input elements' id and name?
You could just build a new <td> and assign document.querySelectorAll('#items tr').length as the x in items-x-...:
function addItem() {
var items = document.querySelector('#items')
, itemcount = items.querySelectorAll('tr').length
, newitemQuantityText = 'items-' + itemcount + '-quantity'
, newitemDescriptionText = 'items-' + itemcount + '-description'
, newitem = document.createElement('tr')
, newitemQuantity = document.createElement('td')
, newitemDescription = document.createElement('td')
, newitemQuantityInput = document.createElement('input')
, newitemDescriptionInput = document.createElement('input');
newitemQuantityInput.id = newitemQuantityText;
newitemQuantityInput.name = newitemQuantityText;
newitemQuantity.appendChild(newitemQuantityInput);
newitemDescriptionInput.id = newitemDescriptionText;
newitemDescriptionInput.name = newitemDescriptionText;
newitemDescription.appendChild(newitemDescriptionInput);
newitem.appendChild(newitemQuantity);
newitem.appendChild(newitemDescription);
document.querySelector('#items').appendChild(newitem);
}
document.querySelector('#add').addEventListener('click', addItem);
<button id="add">add item</button>
<table id="items"></table>
However using good old innerHTML reads way better:
function addItem() {
var items = document.querySelector('#items')
, itemcount = items.querySelectorAll('tr').length;
items.innerHTML += '<tr><td>' +
'<input id="item-' + itemcount + '-quantity" name="item-' + itemcount + '-quantity">' +
'</td><td>' +
'<input id="item-' + itemcount + '-description" name="item-' + itemcount + '-description">' +
'</td></tr>';
}
document.querySelector('#add').addEventListener('click', addItem);
<button id="add">add item</button>
<table id="items">
</table>
You can separately reconstruct the node itself by using
createAttribute()
createElement()

This is not the data oriented approach the question asks for, but a reasonably simple solution is
numRows = table.rows.length;
// Use a regexp so we can replace all instances of the number
// corresponding to what is currently the last table row.
var re = new RegExp((numRows - 1).toString(), "g")
for (var i = 0; i <= originalRow.cells.length - 1; i++) {
var originalHTML = originalRow.cells[i].innerHTML;
var newHTML = originalHTML.replace(re, numRows.toString());
newRow.cells[i].innerHTML = newHTML;
}
Obviously this only works if the number we replace doesn't exist elsewhere in the HTML string, so this is not a particularly good solution.
However, we could use a more complex regexp.
This solution does have the advantage that we don't need to hard-code anything except the parts we want to replace into the regexp.
Therefore, if the HTML in the table were to acquire additional parts in future development this solution will still work, up to the quality of the regexp as already mentioned.
I have a table which looks like the following. The price normally comes from a database this is just for showing the problem I have.
$(document).ready(function() {
$(document).delegate('.amount input[type="text"]','keyup',(function() {
var $this = $(this);
var sub_total = $this.find('.sub_total');
var price = $this.find('.price').text();
var amount = $this.val();
alert(price);
}));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr>
<td><input type="text" name="tickets" id="tickets" class="amount" maxlength="2" autocomplete="off"></td>
<td>Ticket:</td>
<td class="price">20,50</td>
<td class="sub_total"></td>
</tr>
</table>
What I would like to do is: when the user types a number in the field tickets it should update the field sub_total. With the jQuery I have this is not working. When I alert(price) I get undefined. So I wonder how to make the sub_total field with auto updated values. It might also be interesting to know that I have more rows like this beneath this row. So the script should only update the field from one specific row at a time.
What I already tried but without success:
How to get a table cell value using jQuery;
How to get a table cell value using jQuery?;
How to get table cell values any where in the table using jquery
Thanks in advance.
You need to do traverse back up to the parent tr element before you try to find the .sub_title or .price elements.
$(document).ready(function() {
$(document).delegate('.amount input[type="text"]','keyup',(function() {
var $this = $(this);
var $tr = $this.closest("tr");
var sub_total = $tr.find('.sub_total');
var price = $tr.find('.price').text();
var amount = $this.val();
alert(price);
}));
});
Change you code like this
$(document).ready(function() {
$(document).on('input[type="text"].amount', 'keyup', (function() {
var $this = $(this);
var sub_total = $this.closest("tr").find('.sub_total');
var price = $this.closest("tr").find('.price').text();
var amount = $this.val();
alert(price);
}));
});
find() will search for the children. So you should get into the parent tr first before using find().
You can use closest("tr") to get the parent tr element
It's because price and sub_total are not children of the current element (as find is selecting):
var sub_total = $this.find('.sub_total');
var price = $this.find('.price').text();
they are siblings of its parent or more simply children of the container tr.
Try instead:
var sub_total = $this.closest('tr').find('.sub_total');
var price = $this.closest('tr').find('.price').text();
example for a
<table id="#myTable">
I write this:
function setCell( idTab, row, col, text) {
var idCel = idTab + " tbody tr:nth-child(" + row + ") td:nth-child(" + col + ")";
$(idCel).html(text);
}
function getCell( idTab, row, col ) {
var idCel =idTab + " tbody tr:nth-child(" + row + ") td:nth-child(" + col + ")";
return $(idCel).html();
}
setCell( "#myTab", 3, 4, "new value" );
alert( getCell("#myTab", 3, 4);
I have a table and assigned a id to it. Initially there is no content.i.e., just the table tag.
I am using this to clear the table contents
function emptyTable ( tableRef )
{
var resultCount = tableRef.rows.length;
for ( var i=0; i<resultCount; i++)
{
if ( tableRef.rows[tableRef.rows.length-1].cells[0].tagName == "TD" )
{
tableRef.deleteRow(tableRef.rows.length-1);
}
}
}
tableRef will have the table id. For first time i have clear the table and the rows are inserted.
var resultListRef = document.getElementById("showReferencesDet");
var row = resultListRef.insertRow(0);
var newCell = row.insertCell(0);
newCell.innerHTML = 'Select';
var newCell2 = row.insertCell(1);
newCell2.innerHTML = 'Reference Number';
var row = resultListRef.insertRow(resultListRef.rows.length);
var newCell = row.insertCell(0);
name="referenceId" value="' + id + '" />';
newCell.innerHTML = '<input type="checkbox" id="referenceId" name="referenceId" value="' + allVars + '" />';
var newCell2 = row.insertCell(1);
newCell2.innerHTML = RefNo;
It works for the first time but didn't works in the 2nd time.
Please help to solve it.
just change your for loop
function emptyTable ( tableRef )
{
document.getElementById(tableRef).innerHTML='';
}
Instead of:
var row = resultListRef.insertRow(resultListRef.rows.length);
you can do:
var row = resultListRef.insertRow(-1);
and the row will be inserted as the last row.
Removing the rows of a table doesn't necessarily remove all content, it may still contain empty text nodes, thead and tfoot elements, etc. Consider:
function emptyTable ( tableRef ) {
while (tableRef.firstChild) {
tableRef.removeChild(tableRef.firstChild);
}
}
That will clear everything from inside the table (but not properties and attributes of the table itself) as if you had <table ... ></table>.
However, you may want to keep header rows and footers. In that case, you just want to remove the tBody elements:
function emptyTableBodies ( tableRef ) {
var tBodies = tableRef.tBodies;
for (var i=tBodies.length; i;) {
tableRef.removeChild(tBodies[--i]);
}
}
so you can do:
<table id="t0">
<thead>
<tr><th>head
</thead>
<tr><td>0
<tr><td>0
<tr><td>0
<tr><td>0
</table>
<button onclick="emptyTableBodies(document.getElementById('t0'))">Empty table bodies</button>
Note that a table with no content is not valid, so fix that as soon as you can after the above.
I have created table dynamically using javascript, want to add a "href" link with the image to the table cell when table created dynamically and increase the width and height of the table cell.Please see "http://jsfiddle.net/c3X8Y/1/". In "Action" columnn of the table i want to display the href links and want to increase the width and height of the table cells.Below is the code.
HTML code:
<input type="file" name="fileUpload" size="50" id="fileUploadID" multiple/></td>
</tr><br>
</table>
</td></tr> <tr><td>
<br/> <table border="1" id="uploadTable" style="visibility:hidden">
<tr> <th>SNo</th><th>FileName</th><th>Action</th> </tr>
</table>
Javascript code:
<script>
var rowN = 1;var count = 1;var a=1;
document.getElementById("fileUploadID").onchange = function() {
document.getElementById("uploadTable").style.visibility="visible";
var fileNameIndex = document.getElementById('fileUploadID').value.lastIndexOf("\\");
var file_name = document.getElementById('fileUploadID').value.substring(fileNameIndex + 1);
// Get a reference to the table
var tableRef = document.getElementById('uploadTable');
// Insert a row in the table at row index 1
var newRow = tableRef.insertRow(rowN);
// Insert a cell in the row at index 0
var newCell = newRow.insertCell(0);
// Append a text node to the cell
var newText = document.createTextNode(rowN);
newCell.appendChild(newText);
// Insert a cell in the row at index 1
var newCell2 = newRow.insertCell(1);
// Append a text node to the cell
var newText2 = document.createTextNode(file_name);
newCell2.appendChild(newText2);
// Insert a cell in the row at index 2
var newCell2 = newRow.insertCell(2);
// Append a text node to the cell
var newText2 = document.createTextNode('delete');
newCell2.appendChild(newText2);
rowN++;
}
</script>
Instead of creating an html element, you're creating a textNode in the following code:
// Append a text node to the cell
var newText2 = document.createTextNode('delete' +'show');
newCell2.appendChild(newText2);
instead, you actually have to create html elements using createElement() function as follows:
// Append a text node to the cell
var newText2 = document.createElement('a'); //create actual HTML element
newText2.innerHTML='show'; // set the elements properties
newText2.href="#";
newCell2.appendChild(newText2);
JSFiddle
this is just for demo purpose, you can actually create the remaining anchor and set all of their properties as shown above...
Update
As for changing the size, simply specify it in css as follows:
td{
width:250px;
height:250px;
}
JSFiddle
Update
You can set the height and width of dynamically created elements as follows:
newCell.style.width ='250px';
newCell.style.height ='250px';
For displaying an image, instead of creating an <a> simply create <img> and set it's source and do your logic on it's click event.
