Is there any way to do that? Thanks in advance.I hope i will find out my answer through you guys.Thank you.
The jQuery .clone() method offers the option to also clone events. Please note that by default this option is not used. In order to clone events you need to use:
$(this).clone(true).insertAfter(this);
More detail at jQuery.clone()
I want to note that the .clone() method in jQuery only clones DOM elements. In order to clone JavaScript objects, you would do:
// Shallow copy
var newObject = jQuery.extend({}, oldObject);
// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);
More information can be found in the jQuery documentation.
I also want to note that the deep copy is actually much smarter than what is shown above – it's able to avoid many traps (trying to deep extend a DOM element, for example). It's used frequently in jQuery core and in plugins to great effect.

I'm trying to show a set of select option base on what is selected on another select option. I have some issue to understand the logic with the js script.
Example:
Any advice how to hide the other options which are not used
if TV show only value device, tsignal, blackscreen, other
If Radio show only the value: device, rsignal, other
$('#new').find('option').not('[value="device"]').remove();

<option value="tv">tv</option>
<option value="radio">radio</option>
</select>
</td>
</tr>
<tr>
<td height="50px" colspan="3"></td>

<tr>
<td>What is the problem?</td>

<select id="new" name="new">

<option value="rsignal">radio has no signal</option>

I guess that you meant to use .change so when #test dropdown changed you check what its value and based on that show / hide options, right?
$('#test').change(function() {
const options = $('#new').find('option').show();
if ($(this).val() === 'tv') {
options.not('[value="device"]').hide();
}
});

Notice Hide option is not cross browser
In a table, I have two columns and many rows. One column have drop down and other have input field of type number. When I change the value of drop down I want to assign that selected value to the input field which is present in next td. I hope I explained my problem okay.
Here is what I have tried,
$(document).ready(function() {
$('select.nameSelect').change(function() {
var id = $(this).children("option:selected").val();
$(this).closest('.tr').find('.StudentId').val(id);
});
});

</select>
</td>
<td>
<input type="number" class="StudentId" />
</td>
</tr>

Firstly, your HTML is invalid due to having multiple elements with the same id (id="StudentName").
But the reason your code isn't working is because you're doing closest('.tr') when it should be closest('tr') because it's an element, not a class.
Also, there is no need to find the selected value... just use this.value
$(document).ready(function() {
$('select.nameSelect').change(function() {
$(this).closest('tr').find('.StudentId').val(this.value);
});
});

Here create a dynamic table row when clicking on + button add a new row and click on - button remove row design like this,
Here subject drop-down display and also instructor drop-down display but the problem is when select subject maths instructor drop-down show and when select a science instructor drop-down hide but it's changing in all drop-down.

That happens because of duplicate identifiers, the id attribute must be unique in the same document.
That will be fixed by replacing the duplicate ones with common classes.
Then your selector could be simply :
$(this).closest('tr').find('.instructor_name');
$('body').on('change', '.course_topic', function() {
var topic_name = $(this).val();
var names = ['Registration', 'Lunch Break', 'Tea Break'];
var instructor_name = $(this).closest('tr').find('.instructor_name');
if ($.inArray(topic_name, names) != -1) {
instructor_name.hide();
} else {
instructor_name.show();
}
});

We are using Parsley JS for client side validation and I have following scenario which I need to validate.
The HTML part looks like this:
<form id="demo-form">
<table>
<tr>
<td>
Do you want to enter values:
<input type="radio" name="choice" value="yes"> Yes
<input type="radio" name="choice" value="no"> No
</td>
</tr>
<tr>
<td>
<table>
<tr>
<td>Select Year</td>
<td>
<select name="year" title="Select Year">
<option value="Year">Year</option>
<option value="2017">2017</option>
<option value="2018">2018</option>
<option value="2019">2019</option>
<option value="2020">2020</option>
</select>
</td>
<td>
<select name="year" title="Select Year">
<option value="Year">Year</option>
<option value="2017">2017</option>
<option value="2018">2018</option>
<option value="2019">2019</option>
<option value="2020">2020</option>
</select>
</td>
<td>
<select name="year" title="Select Year">
<option value="Year">Year</option>
<option value="2017">2017</option>
<option value="2018">2018</option>
<option value="2019">2019</option>
<option value="2020">2020</option>
</select>
</td>
</tr>
<tr>
<td>Enter Amount</td>
<td>
<input type="text" name="amount" size="3"/>
</td>
<td>
<input type="text" name="amount" size="3"/>
</td>
<td>
<input type="text" name="amount" size="3"/>
</td>
</tr>
</table>
</td>

Validation requirements are:
User has to choose "Yes" or "No" (Choice filed is required).
If user chooses "Yes" then at least one drop down year need to be
selected.
For any drop down whose year is selected needs to have some value.
(Amoount filed not empty)
If user chooses "No" then Year fields can be kept on default value and amount can be left blank.
I would like to know if this type of validation can be achieved easily and efficiently in Parsley? I have created working copy for testing at the following URL Working example - CodePen Link
I would really appreciate if somebody with better experience on Parsley JS, can comment on this.
So far i have a dropdown which each has a corresponding number which works just fine. Each number also has a corresponding trait also which will be placed in the 4th column. So what i'm trying to ask is can the dropdown have two values attached to it (a number and a trait) or should I break it up into two parts (1: dropwdown displays a number & 2: number displays a trait)? and how to do that please and thanks you.

You can bind additional values to your DOM elements using data attributes. Here is how you do that.
JS
$('#warmth').change(function () {
$('#warmthVal').val(this.value);
$('#warmthTrait').val($(this).data("trait"));
});
HTML
<table>
<tr>
<td><b>Factors</b></td>
<td><b>Sten Score</b></td>
<td><b>1-10</b></td>
<td><b>Personality Traits</b></td>
</tr>
<tr>
<td>Warmth (A)</td>
<td>
<select name="warmth" id="warmth">
<option value="">...</option>
<option data-trait="trait1" value="1">0-4</option> //trait1
<option data-trait="trait2" value="2">5-6</option> //trait2
<option data-trait="trait3" value="3">7-9</option> //trait3
<option data-trait="trait4" value="4">10-11</option> //trait4
<option data-trait="trait5" value="5">12-14</option> //trait5
...
</select>
</td>
<td>
<input type="text" id="warmthVal" name="sten" disabled size="1" />
</td>
<td>
<input type="text" id="warmthTrait" name="warmthTrait" disabled size="1" />
</td>
</tr>

Hope it helps.
