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

I have a table like this
<table style="width:100%">
<tr>
<th>Downpayment (%)</th>
<th>Downpayment (₱)</th>
<th>Balance</th>
<th>Payment Period (Months)</th>
<th>MA 1 - XX</th>
<th>MA 1 - XX (VAT)</th>
</tr>
<tr>
<td class="dp-perce" data-perce="0">0%</td>
<td class="dp-peso"></td>
</tr>
<tr>
<td class="dp-perce" data-perce="15">15%</td>
<td class="dp-peso"></td>
</tr>
<tr>
<td class="dp-perce" data-perce="30">30%</td>
<td class="dp-peso"></td>
</tr>
<tr>
<td class="dp-perce" data-perce="50">50%</td>
<td class="dp-peso"></td>
</tr>
<tr>
<td class="dp-perce" data-perce="95">95%</td>
<td class="dp-peso"></td>
</tr>
</table>
whenever I use closest(), it is always returning null. what seems to be the problem?
here is my jquery:
<script>
$('#unit-type').on('change', function() {
$('.dp-peso').each(function(){
var percentage = $(this).closest('td').find('.dp-perce').data('perce');
$(this).text(percentage);
});
});
</script>
what this script is doing is to get the value of data-attribute of the closest dp-perce then display to class name dp-peso.
please let me know the bug. I've been stuck here for a long time/
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>

This method will give you the html of the required table.
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">

I have this code
<table>
<tr id="groupItem-12863">
<td>10</td>
<td class="selCost">34</td>
</tr>
<tr id="groupItem-12863">
<td>20</td>
<td class="selCost">5</td>
</tr>
<tr>
<td>14</td>
<td class="selCost">23</td>
</tr>
<tr id="groupItem-73632">
<td>28</td>
<td class="selCost">8</td>
</tr>
<tr id="groupItem-73632">
<td>54</td>
<td class="selCost">55</td>
</tr>
<tr id="groupItem-73632">
<td>13</td>
<td class="selCost">99</td>
</tr>
<tr>
<td>18</td>
<td class="selCost">55</td>
</tr>
<tr>
<td>99</td>
<td class="selCost">66</td>
</tr>
</table>
I want a jquery selector where I can loop over the group of id and fetch the value of td cell. Note: the tr id are generated dynamically and can have none or N rows for each group of id. For example (groupItem-12863 has 2 and groupItem-73632 has 3 rows)
Even if the following solution should do what you are expecting, I strongly suggest you to change the id to another attribute, a custom one like group-id or use CSS classes. By the way:
$(function() {
var groupedRows = {};
$.each($('tr[id^=groupItem]'), function() {
if (groupedRows[$(this).attr('id')]) {
groupedRows[$(this).attr('id')].push($(this));
}
else {
groupedRows[$(this).attr('id')] = [$(this)];
}
});
console.log(groupedRows);
});
HTML must not have same ids, it will be better to use class for your use-case.
After this you can get the elements with a given class and loop over them like
$(function(){
$('.groupItem-73632').each(function() {
console.log('grp');
$(this).find('td').each(function(){
console.log($(this).text());
})
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr class="groupItem-12863">
<td>10</td>
<td class="selCost">34</td>
</tr>
<tr class="groupItem-12863">
<td>20</td>
<td class="selCost">5</td>
</tr>
<tr>
<td>14</td>
<td class="selCost">23</td>
</tr>
<tr class="groupItem-73632">
<td>28</td>
<td class="selCost">8</td>
</tr>
<tr class="groupItem-73632">
<td>54</td>
<td class="selCost">55</td>
</tr>
<tr class="groupItem-73632">
<td>13</td>
<td class="selCost">99</td>
</tr>
<tr>
<td>18</td>
<td class="selCost">55</td>
</tr>
<tr>
<td>99</td>
<td class="selCost">66</td>
</tr>
</table>
I had to do bit of hack, I know the html was not ideal, we can't have same id's. But sometimes refactoring the older code is out of scope. Here is the solution, not ideal but works :
$('tr[id^=groupItem-]').each(function(){
var s = 0 ;
var text = $(this).attr('id');
var arr = text.split('-');
var elem = 'tr[id^=groupItem-' + arr[1] + ']';
$(elem).find("td.selCost").each(function(){
s += parseFloat($(this).text());
});
console.log($(this).attr('id')+ '=='+s);
});
You can use the wildcard selector like tr[id^=groupItem]. Check Attribute Selector for more example.
$(function() {
$('tr[id^=groupItem]').css({
'background-color': 'red'
});
});

In the above jquery function, list1 and list2 are horizontally connected to lqwasc10 and lqwasc11 respectively. Is there a way I can align list1 and list2 vertically along with existing td elements of Components and Properties in their respective orders.
I've tried a lot and couldn't get hold of the logic. It would be great if someone can answer.
I'm expecting data in the format as shown in the screenshot.
You can merely add the desired <td>s just after removing duplicates, like this:
var list1 = [1,2,3,4,5,6];
var list2 = [6,5,4,3,2,1];
$(document).ready(function(){
$('.comps + .comps').remove();
$('.myTable tr').each(function(i) {
if (i > 0) {
$(this)
.append('<td>' + list1[i - 1] + '</td>')
.append('<td>' + list2[i - 1] + '</td>');
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="serverSet">
<h2>JH Storefront servers</h2>
