Manipulating rows and columns in HTML table with multi-row cells - javascript

I have an html table with cells that span multiple rows:
<table border="1" style=""><tbody id="x">
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td rowspan="3">**</td>
<td>AAAA</td>
<td> </td>
</tr>
<tr id="row2">
<td>BBBB</td>
<td> </td>
</tr>
<tr>
<td>CCCC</td>
<td> </td>
</tr>
<tr>
<td style=""> </td>
<td id="ee">EEEE</td>
<td> </td>
</tr>
<tr>
<td style=""> </td>
<td id="dd">DDDD</td>
<td> </td>
</tr>
</tbody></table>
<script type="text/javascript">
alert ("index of dd before delete =" + document.getElementById("dd").cellIndex);
document.getElementById("row2").style.display="none";
alert ("index of dd after delete =" + document.getElementById("dd").cellIndex);
</script>
I am trying to manipulate it in Javascript, eg hide row2.
When I do that, the multi-row cell containing "**" moves down, shifting all the cells in row 3 by 1 to the right. Evidently I have to reduce its rowSpan.
But it seems when I am looking at row 1, I have no way of knowing that there is a multi-row cell intersecting this row - it seems I have to scan all the rows above row2 for multi-row cells.
Is there a better/quicker way to find out what multi-row cells affect the hiding (or deleting) operation?

Try this using javascript... It is working properly.
Change the value of currRowToDelete for Range [1 to 6].
Refer for working code: http://jsfiddle.net/arunkumrsingh/cdS2D/1/
<table id="tbl" border="1" runat="server" >
<tr id="row1">
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr id="row2">
<td rowspan="3">**</td>
<td>AAAA</td>
<td> </td>
</tr>
<tr id="row3">
<td>BBBB</td>
<td> </td>
</tr>
<tr id="row4">
<td>CCCC</td>
<td> </td>
</tr>
<tr id="row5">
<td style=""> </td>
<td id="ee">EEEE</td>
<td> </td>
</tr>
<tr id="row6">
<td style=""> </td>
<td id="dd">DDDD</td>
<td> </td>
</tr>
</table>
<script type="text/javascript">
var trs = document.getElementById("tbl").getElementsByTagName("tr");
var tds;
var bDeleted = false;
var currRowToDelete = 3;
for(var i=0;i<currRowToDelete;i++)
{
tds = trs[i].getElementsByTagName('td');
for(var j=0;j<tds.length;j++)
{
var currRowSpan = tds[j].rowSpan;
if(currRowSpan > 1)
{
if(eval(i + 1) == currRowToDelete)
{
var cell = document.createElement("td");
cell.innerHTML = tds[j].innerHTML;
trs[i + 1].insertBefore(cell, trs[i + 1].getElementsByTagName('td')[0]);
document.getElementById("tbl").deleteRow(i);
bDeleted = true;
document.getElementById("tbl").rows[i].cells[0].rowSpan = eval(currRowSpan -1);
}
else
{
if(eval(currRowSpan + i) >= currRowToDelete)
document.getElementById("tbl").rows[i].cells[0].rowSpan = eval(currRowSpan -1);
}
}
}
}
if(bDeleted == false)
document.getElementById("tbl").deleteRow(currRowToDelete -1);
</script>

I have a solution, in which you don't have to calculate the Rowspan and Colspan.
Step 1: Get the content of HTML (As mentioned above) and save as EXCEL file.
Step 2: Delete the particular Row (ie Row 2).
Step 3: Save as HTML file and Read the HTML content.
You will get the HTML in correct format.

How to make rowspan add 1 and new row added last with javascript jquery?

Here I want to add new row under name and age. The colspan of ApplyPeople will be added to 1.But I failed, here is my JS code:
$(document).ready(function()
{
$('#add').click(function () {
newrow = '<tr><td style="width:25%">John</td><td style="width:55%">20</td></tr>';
$('#apply').rowspan = $('#apply').rowspan + 1;
$('#staTable tr:xie').append(newrow);
});
}
Before click, html code:
<tr>
<td style="width:20%" rowspan=1 id="apply">
applyPeople<br />
<input type="button" id="add" value="add">
</td>
<td style="width:25%">name</td>
<td style="width:55%">age</td>
</tr>
<tr>
<td style="width:20%">zone</td>
<td style="width:80%" colspan=2>letter</td>
</tr>
After click, html code:
<tr>
<td style="width:20%" rowspan=2 id="apply">
apply<br />
<input type="button" id="add" value="add">
</td>
<td style="width:25%">name</td>
<td style="width:55%">age</td>
</tr>
<tr id="xie" >
<td style="width:25%">John</td>
<td style="width:55%">20</td>
</tr>
<tr>
<td style="width:20%">zone</td>
<td style="width:80%" colspan=2>letter</td>
</tr>
What is wrong with my code? Who can help me?
You can use jQuery's .attr() to achieve what you want:
Comments in code for js, - and also in your html, start your rowspan off as 2 (or the number of rows you start in your table) and get rid of the colspan in the second row - the rowspan handles the missing column
$('#addPeople').click(function () {
newrow = '<tr><td style="width:25%">John</td><td style="width:55%">20</td></tr>';
var rowspan = parseInt($('#appPeople').attr('rowspan')) + 1; // use attr to get the rowspan and parseInt to make it an int
$('#appPeople').attr('rowspan', rowspan); // use attr to set the rowspan
$('#staTable tr:eq(0)').after(newrow); // use after if you want to add it after the first row, eq(0) means get the first instance of
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="staTable">
<tr>
<td style="width:20%" rowspan=2 id="appPeople">
applyPeople<br />
<input type="button" id="addPeople" value="">

How to get a first td values of every table using JQuery?

I want to select all first td values using JQuery.
Here is my code:
<tr id="#ASPxGridView1_DXHeadersRow0">
<td id="ASPxGridView1_col0" class="dxgvHeader" onmousedown="ASPx.GHeaderMouseDown('ASPxGridView1', this, event);" style="border-top-width:0px;border-left-width:0px;">
<table style="width:100%;">
<tbody>
<tr>
<td>Status</td>
<td style="width:1px;text-align:right;"><span class="dx-vam"> </span></td>
</tr>
</tbody>
</table>
</td>
<td id="ASPxGridView1_col1" class="dxgvHeader" onmousedown="ASPx.GHeaderMouseDown('ASPxGridView1', this, event);" style="border-top-width:0px;border-left-width:0px;">
<table style="width:100%;">
<tbody>
<tr>
<td>Worksheet ID</td>
<td style="width:1px;text-align:right;"><span class="dx-vam"> </span></td>
</tr>
</tbody>
</table>
</td>
</tr>
I want to get only 2 td (Status.Worksheet ID) elements from my above code using JQuery
You can pass any valid CSS selector to JQuery, so all you need is:
$("td:first-child");
// This will find and group together all the `<td>` elements that are the first ones
// within their parent (<tr>).
var $results = $("td:first-child");
// You can loop over the set and work with the individual DOM elements...
$results.each(function(index, result){
// result is the DOM element we're looping over
console.log(result.textContent);
});
// Or, you can access a specific element by index:
console.log($results[0].textContent + ", " + $results[1].textContent);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<tr id="#ASPxGridView1_DXHeadersRow0">
<td id="ASPxGridView1_col0" class="dxgvHeader" onmousedown="ASPx.GHeaderMouseDown('ASPxGridView1', this, event);" style="border-top-width:0px;border-left-width:0px;"><table style="width:100%;">

Calculating sum of td classes using js or jQuery

I have a dropdown select menu with various options (i.e. 5, 10, 15, 20...) that represents # of computers. The default select menu value is 5. I am using some js to multiply the dropdown selection by an amount (i.e. 10) and populates a table td with a class of .price-1. So, for example if the user leaves the default selection of 5, the calculated value of .price-1 is 50.
This is working fine. 
However, I then need to sum .price-1 with a few other <td> classes (i.e. .price-2, .price-3, .price-4...) to get a grand total in $ values that shows in #result.
How can I use js or jQuery to sum these td classes to get the grand total?
Below is my html of my table I need to sum.
<table id="tableOrderTotal" class="table tableTotal">
<tbody>
<tr>
<td>Item1</td>
<td class="price-1">calculated amount populated here</td>
</tr>
<tr>
<td>Item2</td>
<td class="price-2">calculated amount populated here</td>
</tr>
<tr>
<td>Item3</td>
<td class="price-3">13</td>
</tr>
<tr>
<td>Item3</td>
<td class="price-4">30</td>
</tr>
<tr class="summary">
<td class="totalOrder">Total:</td>
<td id="result" class="totalAmount"> </td>
</tr>
</tbody>
</table>
Get all td elements either using attribute value contains selector or by second td element of tr using :nth-child(). Now iterate over them using each() method and get sum using the text inside.
var sum = 0;
$('td[class*="price-"]').each(function() {
sum += Number($(this).text()) || 0;
});
$('#result').text(sum);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="tableOrderTotal" class="table tableTotal">
<tbody>
<tr>
<td>Item1</td>
<td class="price-1">calculated amount populated here</td>
</tr>
<tr>
<td>Item2</td>
<td class="price-2">calculated amount populated here</td>
</tr>
<tr>
<td>Item3</td>
<td class="price-3">13</td>
</tr>
<tr>
<td>Item3</td>
<td class="price-4">30</td>
</tr>
<tr class="summary">
<td class="totalOrder">Total:</td>
<td id="result" class="totalAmount"></td>
</tr>
</tbody>
</table>
With Array#reduce method as #rayon suggested.
$('#result').text([].reduce.call($('td[class*="price-"]'), function(sum, ele) {
return sum + (Number($(ele).text()) || 0);
}, 0));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="tableOrderTotal" class="table tableTotal">
<tbody>
<tr>
<td>Item1</td>
<td class="price-1">calculated amount populated here</td>
</tr>
<tr>
<td>Item2</td>
<td class="price-2">calculated amount populated here</td>
</tr>
<tr>
<td>Item3</td>
<td class="price-3">13</td>
</tr>
<tr>
<td>Item3</td>
<td class="price-4">30</td>
</tr>
<tr class="summary">
<td class="totalOrder">Total:</td>
<td id="result" class="totalAmount"></td>
</tr>
</tbody>
</table>
jQuery Object has a direct attribute referring to the number of the matched elements.
var sum = $('td[class*="price-"]').length;
$('#result').text(sum);

Sorting tr elements alphabetically

I'm trying to sort tr but I've no luck by far.
Here is my tr structure.
<tr>
<td>
<a href="./BlueSky-TexasHealthResources/index.php" >Blue Sky-Texas</a>
</td>
<td>
View Data
</td>
<td id="blue_sky_texas">
</td>
</tr>
<tr>
<td id = 'bj'>
<a href="./BountyJobs/index.php" >Bounty Jobs</a>
</td>
<td>
View Data
</td>
</tr>
Here is Javascript that I've tried by far.
<script type="text/javascript">
var $tr = $("tr");
$(document).ready(function () {
var alphabeticallyOrderedTr = $tr.sort(function (a, b) {
return $(a).find("a:first").text().toLowerCase().localeCompare($(b).find("a:first").text().toLowerCase());
});
$("#container").html(alphabeticallyOrderedTr);
});
</script>
And below is the image for table (unsorted using above code :( ).
.sort() is Array.prototyope method, not jQuery method. Try adding .get() or .toArray() before .sort(function(){}) called ; e.g., $tr.get().sort(
$(document).ready(function() {
var $tr = $("tr");
var alphabeticallyOrderedTr = $tr.get().sort(function(a, b) {
return $(a).find("a:first").text().toLowerCase().localeCompare($(b).find("a:first").text().toLowerCase());
});
$("#container").append(alphabeticallyOrderedTr);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<table id="container">
<tr>
<td>
<a>Y Jobs</a>
</td>
</tr>
<tr>
<td>
<a>Z Jobs</a>
</td>
</tr>
<tr>
<td id='bj'>
Bounty Jobs
</td>
<td>
View Data
</td>
</tr>
<tr>
<td>
<a>X Jobs</a>
</td>
</tr>
<tr>
<td>
Blue Sky-Texas
</td>
<td>
View Data
</td>
<td id="blue_sky_texas">
</td>
</tr>

jquery auto print the row number

i've a table with 10 row, is it possible to print the row number (from 1 to 9, the first row is NO&title, the second row should be 1) to the td with class "sno" based on the size of the table? here is the html:
<table width="100%" border="1">
<tr>
<td width="23%">No.</td>
<td width="77%">Title</td>
</tr>
<tr>
<td class="sno"> </td>
<td> </td>
</tr>
<tr>
<td class="sno"> </td>
<td> </td>
</tr>
<tr>
<td class="sno"> </td>
<td> </td>
</tr>
<tr>
<td class="sno"> </td>
<td> </td>
</tr>
<tr>
<td class="sno"> </td>
<td> </td>
</tr>
<tr>
<td class="sno"> </td>
<td> </td>
</tr>
<tr>
<td class="sno"> </td>
<td> </td>
</tr>
<tr>
<td class="sno"> </td>
<td> </td>
</tr>
<tr>
<td class="sno"> </td>
<td> </td>
</tr>
the result should be
<table width="100%" border="1">
<tr>
<td width="23%">No.</td>
<td width="77%">Title</td>
</tr>
<tr>
<td class="sno">1</td>
<td> </td>
</tr>
<tr>
<td class="sno">2</td>
<td> </td>
</tr>
<tr>
<td class="sno">3</td>
<td> </td>
</tr>
<tr>
<td class="sno">4</td>
<td> </td>
</tr>
<tr>
<td class="sno">5</td>
<td> </td>
</tr>
<tr>
<td class="sno">6</td>
<td> </td>
</tr>
<tr>
<td class="sno">7</td>
<td> </td>
</tr>
<tr>
<td class="sno">8</td>
<td> </td>
</tr>
<tr>
<td class="sno">9</td>
<td> </td>
</tr>
The question is not generate the table, it is print the right number to target
Try with the simpleone
$('table tbody tr').not(":first").each(function(idx){
$(this).children(":eq(0)").html(idx + 1);
});
Here is the jsfiddle example: http://jsfiddle.net/3BBEN/
$(document).ready(function(){
//use a special class name or id for the table
//using find I'm getting all tr elements in the table
//using not(':eq(0)') I'm ignoring the first tr element
//using each I'm iterating through the selected elements
$('table').find('tr').not(':eq(0)').each(function(i){
//using children('td:eq(0)') I'm getting the first td element inside the tr
$(this).children('td:eq(0)').addClass('sno').text(i+1);
});
});
Table row elements have a rowIndex property that is the zero–based sequence number for the table
section that they are in. So if you have a reference to a cell you can use:
var rowIndex = cell.parentNode.rowIndex;
If you have header rows in a table, you probably should put them in a thead table section, then
you can number the rows in tbody section easily, e.g.
<table>
<thead>
<tr>
<td>head<td>head
</tr>
</thead>
<tbody>
<tr>
<td class="sno"></td>
<td>...</td>
</tr>
<tr>
<td class="sno"></td>
<td>...</td>
</tr>
</tbody>
</table>
So now you can do something like:
window.onload = function() {
var table = document.getElementsByTagName('table')[0];
var rows = table.tBodies[0].rows;
for (var i=0, iLen=rows.length; i<iLen; i++) {
rows[i].cells[0].innerHTML = i + 1;
}
};
Of course you can get the rows some other way (e.g. class), but the above is independent of that.
Try this:
$(document).ready(function(){
$cells=$("table td.sno");
for(var i=0;i<$cells.length;i++)
{
// alert(i);
$cells.eq(i).text(i);
}
});
Check on fiddle http://jsfiddle.net/qcWec/1/
try this::
$(document).ready(function(){
var i=1;
$('.sno').each(function(){
$(this).text(i);
i++;
});
});
