jquery auto print the row number - javascript

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++;
});
});

Edit/Print <input> field via Console

Here is what I have. Nothing has IDs, Names or Classes.
Is there anyway to enter a vaue in the input field under City using the Chrome Console and js? Alternatively is there a way I can print the value of said field also using js in the Chrome Console?
I assume it requires using the div City and traversing to next input.
Thanks ahead of time!

document.getElementsByTagName("table")[3].getElementsByTagName("input")[0].value="your value"

The boilerplate code
var tables = document.getElementsByTagName("table");
for (var i = 0; i < tables.length; i++) {
try {
var field = document.getElementsByTagName("table")[i].getElementsByTagName("div")[0].textContent;
if (field == "City") {
document.getElementsByTagName("table")[i + 1].getElementsByTagName("input")[0].value = "your values"
}
} catch (err) {}

Get text of specific element by index

I want to get the text of the second to last table row, so I tried to do this:
var tradeNumEl = $("td.trade-num").length - 2;
console.log($("td.trade-num")[tradeNumEl].text())
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tr>
<td class="trade-num">100</td>
</tr>
<tr>
<td class="trade-num">101</td>
</tr>
<tr>
<td class="trade-num">102</td>
</tr>
<tr>
<td class="trade-num">103</td>
</tr>
<tr>
<td class="trade-num">104</td>
</tr>
<tr>
<td class="trade-num">105</td>
</tr>
</table>
However it gives me:
Uncaught TypeError: $(...)[tradeNumEl].text is not a function
How can I fix this? Here's the fiddle: https://jsfiddle.net/45a9sc6k/4/

Accessing a jQuery object by index returns the Element object at that index of the collection. It does not return a jQuery object - hence your error. To fix this, use eq() instead:
console.log($("td.trade-num").eq(tradeNumEl).text());
var tradeNumEl = $("td.trade-num").length - 2;
console.log($("td.trade-num").eq(tradeNumEl).text());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tr>
<td class="trade-num">100</td>
</tr>
<tr>
<td class="trade-num">101</td>
</tr>
<tr>
<td class="trade-num">102</td>
</tr>
<tr>
<td class="trade-num">103</td>
</tr>
<tr>
<td class="trade-num">104</td>
</tr>
<tr>
<td class="trade-num">105</td>
</tr>
</table>

You have to use eq() with index no as parameter. .eq(index) Reduce the set of matched elements to the one at the specified index.
var tradeNumEl = $("td.trade-num").length - 2;
console.log($("td.trade-num").eq(tradeNumEl).text() )
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr>
<td class="trade-num">100</td>
</tr>
<tr>
<td class="trade-num">101</td>
</tr>
<tr>
<td class="trade-num">102</td>
</tr>
<tr>
<td class="trade-num">103</td>
</tr>
<tr>
<td class="trade-num">104</td>
</tr>
<tr>
<td class="trade-num">105</td>
</tr>
</table>

You also can create the object of the found element

console.log($($("td.trade-num")[tradeNumEl]).text(), tradeNumEl)

Javascript store table in a variable with conditions

This is how my page looks like:
<div class="bgSmTitle smTitle">Customer Addresses</div>
<table class="bgLtTable">
<tr>
<td class="bgLtRow1 padded">New York</td>
</tr>
<tr>
<td class="bgLtRow1 padded">Osaka</td>
</tr>
<tr>
<td class="bgLtRow1 padded">Los Angeles</td>
</tr>
</table>
<div class="bgSmTitle smTitle">Family Members</div>
<table class="bgLtTable">
<tr>
<td class="bgHeader1 padded" style="width:24%;">Name</td>
<td class="bgHeader2 padded" style="width:10%;">Relationship</td>
<td class="bgHeader1 padded" style="width:30%;">Age</td>
</tr>
<tr>
<td class="bgLtRow1 padded">Jordan</td>
<td class="bgLtRow2 padded">Father</td>
<td class="bgLtRow1 padded">58</td>
</tr>
</table>
I would like to store the tables with class name bgLtTable. These table can appear up to 3-4 times in this page. Is it possible to get the specific table using the div above it? Something like:
var tableAddress = div.innerHtml="Customer Addresses".table.bgLtTable;
var tableMembers = div.innerHtml="Family Members".table.bgLtTable;

Maybe try to use document.getElementsByTagName("TABLE");
This will give you an object that is accessible via index
You can then assign those elements to a variable and loop through it but look where the class attribute is equal to className for example
var element = document.getElementsByTagName("TABLE");
for (var i = 0; element.length > i; i++)
{
var elementClass = element[i].getAttribute('class');
}
I am not 100% sure this answers your question how I understand is you just want to get the class.
I hope this helps I am also pretty new to coding but always willing to help if I can.

var CustomerAddressesTable = $('div.smTitle:contains("Customer Addresses")').next('.bgLtTable');
console.log($("<div />").append($(CustomerAddressesTable).clone()).html());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr class="prnt">
<td>
<div class="bgSmTitle smTitle">Customer Addresses</div>
<table class="bgLtTable">
<tr>
<td class="bgLtRow1 padded">New York</td>
</tr>
<tr>
<td class="bgLtRow1 padded">Osaka</td>
</tr>
<tr>
<td class="bgLtRow1 padded">Los Angeles</td>
</tr>
</table>
</td>
</tr>
<tr class="prnt">
<td colspan="3">
<div class="bgSmTitle smTitle">Family Members</div>
<table class="bgLtTable">
<tr>
<td class="bgHeader1 padded" style="width:24%;">Name</td>
<td class="bgHeader2 padded" style="width:10%;">Relationship</td>
<td class="bgHeader1 padded" style="width:30%;">Age</td>
</tr>
<tr>
<td class="bgLtRow1 padded">Jordan</td>
<td class="bgLtRow2 padded">Father</td>
<td class="bgLtRow1 padded">58</td>
</tr>
</table>
</td>
</tr>
</table>
This method will give you the html of the required table.

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%;">
<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>

How to return the table with javascript or jquery by returning another table with all the rows that contains a td that doesn't have a colspan

How to return the table with javascript or jquery by returning another table with all the rows that contains a td that doesn't have a colspan
<table>
<tr>
<td> text1 </td>
<td> text2 </td>
</tr>
<tr>
<td colspan="2"></td>
</tr>
<tr>
<td colspan="2"></td>
</tr>
<tr>
<td> text3 </td>
<td> text4 </td>
</tr>
</table>
Thus I'm expecting
<table>
<tr>
<td> text1 </td>
<td> text2 </td>
</tr>
<tr>
<td> text3 </td>
<td> text4 </td>
</tr>
</table>

You can use a single line of jQuery for this with the :has selector:
$('table tr:has(td[colspan])').remove();
