How to enable disabled fields using jQuery?

function disableField()
{
var Count = $('#dataTable tr').length;
if (Count == 2){
$("input").not('.DeleteButton').prop('disabled', false);
}else{
$("input").prop('disabled', false);
}
}

$(document).on('click','.Buttons', function(addrow) {
var count = $('table tr:last input:text').filter((_,el) => el.value.trim() == "").length;
if(count || !$('.id_100 option[value=code]').attr('selected','selected')){
alert("Please fill the current row");
return false;

var $tr = $('#dataTable tbody tr:last');
var $clone = $tr.clone(true);

$clone.find(':input').not('select').not('.DeleteButton').val('').attr('disabled', true);
$clone.attr('id', 'id'+(cindex) ); //update row id if required

I have a table with a drop-down column in it. Whenever i change the values of drop-down my corresponding fields get enabled. The problem i am getting is if i change the values of my drop-down of previous row the columns of current row also get enabled.Any help will be appreciated. Thanks.
Edit:I have added 'Add Row' function too in my code.

I have added some changes in your disableField function. Pass parameter(this) disableField(this) in that function on chnage event.
function disableField(elem)
{
var Count = $('#dataTable tr').length;
if (Count == 2){
$(elem).closest('tr').find("input").not('.DeleteButton').prop('disabled', false);
}
else{
$(elem).closest('tr').find("input").prop('disabled', false);
}}

All in all there is to much extraneous code so the following answer has different code yet can be applied to the clunky code provided in question. I recommend that your code be more streamlined like the following demo provided in this answer.
Here's some suggestions:
If you are using multiple form controls (ex. <button>, <input>, <textarea>, <select>, etc), wrap everything into a <form>
If you have multiple tags (aka elements) that the user can click, submit, reset, change, input, etc register the events to the <form>
In order to find the exact form control that was clicked, changed, etc. use the Event.target property to find it or this keyword and the Event.data parameter.
$('form selector').on('event type', Event.data, callback function)
The #id and [name] attributes are unnecessary unless you are using certain Web APIs such as HTMLFormControlsCollection or HTMLFormElement
Never use event attributes (ex onchange="callback()") when using jQuery. Use the proper jQuery method or .on() method.
// jQuery method
$(selector).click(callback)
// .on() method
$(selector).on('click', callback)
Minor details:
The [type] attribute does not apply to the <select> tag.
Use <th> instead of <td> within <thead>
[maxlength] of 500 is ridiculous. Use <textarea> instead of <input>
Details are commented in demo
/*
Register form.io to the 'submit', 'click', and 'change' events
Note the callback function does not have `()` suffixed because it would be
interpreted as: "run function now"
The callback function doesn't run immediately it runs when a registered event is triggered.
*/
$('.io').on('submit click change', eventHandler);
// Define the counter
let counter = 0;
// Always pass the Event Object when defining a callback function
function eventHandler(event) {
// The Event Object has several properties...
// Get the type of event triggered (ie submit, change, or click)
let eType = event.type;
/*
Get the origin element of event
if 'submit' target will be <form>
if 'click' target will be <button>
if 'change' target will be <select>
*/
let eNode = event.target;
// Pass the event type through a switch() function...
switch (eType) {
// if type is 'submit'...
case 'submit':
// Create a deep clone of the first row
let clone = $('.grid tr:first-child').clone(true, true);
// Add clone as the last child of the <tbody>
$('.grid').append(clone);
// On .each() elment with class '.data' found within the clone...
clone.find('.data').each(function(i) {
// disable it
this.disabled = true;
// remove its value
this.value = '';
});
// Increment the counter by 1
counter++;
// Dereference the clone and assign id as row+counter
clone[0].id = `row${counter}`;
/*
Prevent default behavior:
Reset <form>
Send data to a server

event.stopPropagation();

jQuery doesn't display specific hidden content when I use the .show() command

Below is my HTML and jQuery code. jQuery displays the hidden elements, except for the #image4 and #video4 elements, which stay hidden with if I select image or video. All the other elements get displayed correctly.
Any idea why those two won't show?
JS:
$(document).ready(function(){
var fields = jQuery('#image_type');
var select = this.value;
fields.change(function () {
if ($(this).val() == 'image') {
alert($(this).val());
$('#images_pop_up').show();
$('#video1').hide();
$('#video2').hide();
$('#video3').hide();
$('#video4').hide();
$('#image1').show();
$('#image2').show();
$('#image3').show();
$('#image4').show();
$(' #image5').show();
}
else {
$('#images_pop_up').show();
$('#image1').hide();
$('#image2').hide();
$('#image3').hide();
$('#image4').hide();
$('#image5').hide();
$('#video1').show();
$('#video2').show();
$('#video3').show();
$('#video4').show();
$('#image5').show();
}
});
});
HTML:
<div id ="images_pop_up" style="display:none;">
<span id="image1" style="display:none;" ><img src="/uploads/commerce/images/large/easton-163135-wheeled-bag.jpg" border="0" alt="easton-163135-wheeled-bag.jpg" title=" easton-163135-wheeled-bag.jpg " class="productimage"><input type="hidden" name="products_previous_image_lrg" value="easton-163135-wheeled-bag.jpg"><br>Nice bag</span>

What sticks out most to me is that you're copy pasting when you could be putting CSS to work for you by giving them all the same class (or the appropriate groups of elements the same class at least) and then hiding and showing them based on that.
Your bug is probably caused by a slight typo somewhere in the selectors or the place where you're setting the ids in the markup.

try like this
$(document).ready(function () {
var fields = jQuery('#image_type');
var select = this.value;
$('#image_type').change(function () {
if ($(this).val() == 'image') {
alert($(this).val());
$("[id^=image]").show();
$("[id^=video]").hide();
} else {
$("[id^=video]").show();
$("[id^=image]").hide();
}
});
});

jQuery Validation - How to create a method using two or more fields?

I have several start and end dates in my system, in some cases I have several start and end dates in a screen. All of them are grouped in sets of two and have the same behaviour: the start date can't be greater than the end date and the difference between them can't be greater than a user-entered input.
I know that i have to create two methods, one for validating the first case and other for the second case. The problem is that I don't know how to reference the fields, for example:
// A custom method for validating the date range.
$.validator.addMethod("dateRange", function() {
var startDate = $("#startDate").val();
var endDate = $("#endDate").val();
return isDate(startDate) && isDate(endDate) ? Date.parse(startDate) <= Date.parse(endDate) : true;
});
The problem is: this way I hard-coded the input names. This would work if I had only one set of dates per screen, but when I have more than one this won't work. How do I create a method without hard-coding the IDs of the elements that I want to use so as to use it all around the system?
I've read the online documentation in http://jqueryvalidation.org/jQuery.validator.addMethod/ but does seem to handle my problem and I think using groups wouldn't be enough to handle all elements, I probably would have to copy/paste for each set of dates.
I believe if you help me with one of the cases the second will be resolved using the same logic.
EDIT: As requested, here's the HTML

I tend to do this using custom attributes, e.g.:
<input type="text" id="x" data-validate-date="true" data-validate-against="y" value="01/01/2000" />
<input type="text" id="y" value="1/1/2001" />
<input type="text" id="a" data-validate-date="true" data-validate-against="b" value="01/01/2000" />
<input type="text" id="b" value="4/4/2020" />
You can then define your validation rule something like:
$.validator.addMethod("dateRange", function() {
var allValid = true;
var results = [];
var datesToValidate = $("[data-validate-date]");
for(var i = 0; i < datesToValidate.length; i++) {
var d = datesToValidate[i];
var startDate = $(d).val();
var endDateSelector = "#" + $(d).attr("data-validate-against");
var endDate = $(endDateSelector).val();
results[i] = isDate(startDate) && isDate(endDate) && (Date.parse(startDate) <= Date.parse(endDate));
}
for(var j = 0; j < datesToValidate.length; j++) {
if(!(results[j] == true)) {
allValid = false;
}
}
return allValid;
});
I don't know if that's the best way to do it, but I think it could work for you.

I used the approach suggested by Blazemonger and created a method based on equalTo.
$.validator.addMethod("startDateCantBeGreaterThanEndDate", function(value, element, param) {
var target = $(param);
if (this.settings.onfocusout) {
target.unbind(".validate-startDateCantBeGreaterThanEndDate").bind("blur.validate-startDateCantBeGreaterThanEndDate", function() { $(element).valid(); });
}
value > target.val();
});
And used the method the same way equalTo does:
$("form").validate({
rules: {
"filtro.dataInicialSolicitacao": { startDateCantBeGreaterThanEndDate: "#dataFinalSolicitacao" },
},
messages: {
"filtro.dataInicialSolicitacao": { startDateCantBeGreaterThanEndDate: "Type your custom message." },
}
});

I think I declared the "Toaster" class wrong and IE isn't doesn't recognize it as an array. As such, when I call "PopUp(clientId)" on the toaster it fails becuase it doesn't traverse the array.
Additionally, FireFox populates the array correctly in the documents "ready" function...but I'm not sure IE is doing so.
Lastly, since I am still new to JavaScript it (obviously) could be HOW I am creating the classes (as well).
WHERE IT FAILS:
The code fails because the value of "target" is null. This variable is null because IE doesn't seem to traverse the Toaster (array).
this.PopUp = function(clientId) {
var target = null;
jQuery.each(this, function() {
// Hide previous
if (jQuery(this)[0].IsUp)
jQuery(this)[0].PopDown();
if (jQuery(this)[0].ClientId == clientId)
target = jQuery(this)[0];
});
// Show current
target.PopUp();
}
THE FULL CODE SET:
Thanks for the help...

I need help on the following:
<ul>
<li>
This works GREAT in FireFox
</li>
<li>
IE doesn't seem to recognize the Toaster class as being an array.
</li>
</ul>
<div style="width: 300;">
<label style="display:block;color: #660000;">INDIVIDUAL pieces of toast work fine in IE:</label>

<input type="button" value="Up (row 3)" onclick="myToast.PopUp();" />
</div>

HERE IS THE CORRECTED SOLUTION:
// CLASS DEFINITION:
function Toast(clientId, maxHeight, speed) {
// PROPERTIES
this.ClientId = clientId;
this.MaxHeight = maxHeight;
this.Speed = speed;
// METHODS
this.IsUp = function() {
return (jQuery('#' + this.ClientId).children().height() > 0) ? true : false;
}
this.PopUp = function() {
if (this.IsUp()) { return; }
var speed = this.Speed;
var action = '+=' + this.MaxHeight + "px";
// Border
jQuery('#' + this.ClientId).children('div.toastBorder').fadeIn('fast', function() {
jQuery(this).animate({ height: action }, speed, function() {
// Form
jQuery(this).children('div.toastForm').fadeIn('fast');
});
});
this.IsUp(true);
}
this.PopDown = function() {
if (!this.IsUp()) { return; }
var speed = this.Speed;
var action = '-=' + this.MaxHeight + "px";
// Form
jQuery('#' + this.ClientId).children('div.toastBorder').children('div.toastForm').fadeOut('fast');
// Border
jQuery('#' + this.ClientId).children('div.toastBorder').animate({ height: action }, speed, function() {
jQuery(this).fadeOut('fast');
});
this.IsUp(false);
}
}
// CLASS DEFINITION:
function Toaster() {
// PROPERTIES
this.Items = new Array();
// METHODS
this.PopUp = function(clientId) {
var target = null;
jQuery.each(this.Items, function() {
if (jQuery(this)[0].ClientId != clientId) {
if (jQuery(this)[0].IsUp()) {
jQuery(this)[0].PopDown(); // Hide previous
}
}
if (jQuery(this)[0].ClientId == clientId) {
target = jQuery(this)[0];
}
});
if (target != null) {
if (target.IsUp() == false)
target.PopUp();
}
}
this.PopDown = function(clientId) {
jQuery.each(this.Items, function() {
if (jQuery(this)[0].ClientId == clientId)
jQuery(this)[0].PopDown(); // Hide current
});
}
this.Add = function(toast) {
var found = false;
// No duplicates are allowed
jQuery.each(this.Items, function() {
if (jQuery(this.Items)[0].ClientId == toast.ClientId)
found = true;
});
if (!found)
this.Items.push(toast);
}
}
var myToaster;
var myToast;
// DOM EVENT: Document.Ready()
$j(document).ready(function() {
if (myToaster == null)
myToaster = new Toaster();
myToaster.Add(new Toast("row1", 125, 200));
myToaster.Add(new Toast("row2", 125, 200));
myToaster.Add(new Toast("row3", 125, 200));
myToaster.Add(new Toast("row4", 125, 200));
myToaster.Add(new Toast("row5", 125, 200));
});
</script>

The attempt to "subclass" Array by using it as the prototype object for your "Toaster" class is not going to work in IE, for whatever reason. If you debug the "Add" method, you'll notice that calls to "push" don't seem to fail, but they also don't change the length of the Toaster.
Trying to make Javascript act like a nice polite object-oriented language is fraught with peril, particularly when you try and treat the native types (like Array) as if they're implemented in Javascript too.
I'd just keep an array around as part of "Toaster" someplace.
