I could enable the textboxes as I click on the radio button using jquery. But I am not getting as to how to disable them if radio button is changed.

<tr class="jsRadioMasterSlaveContainer">

<input type="radio" name="radioMultiSelectCheckbox" class="jsRadioMaster" value=""> Upto N random selection count

<td style="padding: 3px;">
<input type="text" placeholder="Count" id="" style="width:80px" class="jsRadioSlave" disabled/>

<td style="padding: 3px;">
<input type="text" placeholder="Count" id="" style="width:80px" class="jsRadioSlave" disabled/>
</td>

Jquery
$(".jsRadioMaster").each(function() {
$(this).click(function() {
HandleMasterRadioChange($(this));
});
});
function HandleMasterRadioChange(masterRadio) {
$(masterRadio).closest(".jsRadioMasterSlaveContainer").find(".jsRadioSlave").each(function() {
$(this).attr("disabled", !$(masterRadio).is(':checked'));
});
}
You can use prop(propertyName, function) and return boolen based on radio in same row
$(".jsRadioMaster").change(function() {
$('.jsRadioSlave').prop('disabled',function(){
return !$(this).closest('tr').find('.jsRadioMaster').prop('checked')
})
});

I have the following dynamic table
I want to compare the value of submit Quantity textbox and Stock textbox together to check if Submit Quantity value is greater than stock value for all rows.
When submit Quantity textbox loses focus I want check, if Submit Quantity value is greater than stock, I want show an alert that "Not enough goods exist in stock" and Submit Quantity textbox must receive focus again.
My HTML and C#
<tbody>
#{ var i = 0;}
#foreach (var item in Model)
{
<tr>
<td></td>
<td>
<input type="text" name="[#i].GoodsName" readonly="readonly" asp-for="#item.GoodsName" class="form-control" />
</td>
<td>
<input type="text" name="[#i].BrandName" readonly="readonly" asp-for="#item.BrandName" class="form-control" />
</td>
<td>
<input type="text" name="[#i].Quantity" readonly="readonly" asp-for="#item.Quantity" class="form-control" />
</td>
<td>
<input type="number" onblur="compare()" id="submitQ" class="form-control" />
</td>
<td>
<input type="text" name="stock" id="stock" readonly="readonly" class="form-control" />
</td>
</tr>
}
I have no idea how to do that
Any help will be appreciated
Thanks in advance
Edit:
This is what I have done to achieve the result but it only works on first row Submit Quantity textbox not on second row
function compare() {
$('#submitQ').each(function () {
let submit = $('#submitQ').val();
let quantity = $('#stock').val();
if (submit > quantity) {
alert('Not enough goods!')
$('#submitQ').select();
return false
}
})
You cannot have mutliple elements with same ids instead use class selector .Then , just get value of submit quantity using $(this).val() and stock value using .closest('tr').find('.stock').. then simply compare these values .
Demo Code :
$('.submitQ').on("blur", function() {
//get value of submit qnty
let submit = $(this).val();
//get stock
let quantity = parseInt($(this).closest('tr').find('.stock').val());
if (submit > quantity) {
alert('Not enough goods!')
$(this).focus(); //show focus
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<th>No</th>
<th>Name</th>

Please check my fiddle.
Fiddle
When i enter any data in any rows in slab_range, i need to autofill all the other rows of 'Slab Range' with a value 'No Bid'. If i left blank, nothing has to be filled. Likewise if i enter any data in 'Part Number', all the other rows of 'Part Number' has to be filled with value '2'. The rows are coming from db, so i cant tell how many rows it will be, it should iterate all the rows.
<tr>
<td>
<input size="1" id="sl[0]" name="sl[0]" value="1" type="text">
</td>
<td>
<input size="9" data-validation="required" name="slab_range[]" id="slab_range[]" type="text">
</td>
<td>
<input size="9" name="item_partno[]" id="item_partno[]" type="text">
</td>
</tr>
There you go, now it's your task to refactoring the code because both methods are equals.
var ProcessTable = (function () {
var _slabs, _partsNumber;
var _init = function () {
_slabs = $('input[name^="slab_range"]');
_partsNumber = $('input[name^="item_partno"]');
_slabs.on('blur', _slabBlurHandler);
_partsNumber.on('blur', _partNumberBlurHandler);
};
var _slabBlurHandler = function (e) {
var value = $.trim($(this).val());
if (value !== '') {
_slabs.val('No bid');
} else {
_slabs.val('');
}
$(this).val(value); // Because the previous line override the original value
};
var _partNumberBlurHandler = function (e) {
var value = $.trim($(this).val());
if (value !== '') {
_partsNumber.val('2');
} else {
_partsNumber.val('');
}
$(this).val(value); // Because the previous line override the original value
};
return {
init: _init
}
})();
ProcessTable.init();

I have a Table in which I have checkboxes that onclick on checkboxes I want to know 2 things
ID of the checkbox
ID of the hidden field on same table row
So I do have a hidden field in each row and I want to know what that value is
My checkbox I can see from my Fiddle is GridView1__ctl3_chkOut but then I want jquery to find the value of the hidden field in same table row
I see that GridView1__ctl2_hndTxtId value is 3601 , but I will have many rows ...

});
$('.yesno').on('change', function () {
$(this).closest('tr').find('.yesno').not(this).prop('checked', false);

You already got the ID of the checkbox. To get the value of the hidden input field of the row use the following code:
$('.yesno').on('change', function () {
$(this).closest('tr').find('input[type="hidden"]').val()
});
See this JSfiddle demo
You can find information about the selectors at : https://api.jquery.com/category/selectors/
Taking a part of your fiddle, it looks about:
$tr = $(this).closest('tr');
hidden = $tr.find('input[type="hidden"]');
console.log(hidden);
Use the find method as you are already using but with 'input[type=hidden]':
$('.out').on('change', function () {
var $tr = $(this).closest('tr');
$tr.find('.out').not(this).prop('checked', false);
console.log(this.id);
//what is the hidden field value in same row?
var hiddenVal = $tr.find('input[type=hidden]').val();
console.log(hiddenVal);
});
$('.yesno').on('change', function () {
var $tr = $(this).closest('tr');
$tr.find('.yesno').not(this).prop('checked', false);
//what is the hidden field value in same row?
var hiddenVal = $tr.find('input[type=hidden]').val();
console.log(hiddenVal);
});
Fiddle
You already have the id of the checkbox. You can get the id of the hidden input element using:
var hiddenID = $(this).closest('tr').find('input[type=hidden]').prop('id');
And you can get the value of the same field like so:
var hiddenVal = $(this).closest('tr').find('input[type=hidden]').val();
I have table structure like this below html code. Here i have a selectbox which is populated on page load from my database, i have given a inline function on the selectbox in order to call if user changes the selectbox value.. but its not calling the jquery function onChange of selectbox .. Please can you see why?

My jquery:
$(document).ready(function() {

Try using the jQuery .on('change') function:
$(document)ready(function() {
$('body').on('change', '#activity_option_id', function() {
alert('test');
});
});
Also see .on() jQuery Documentation
EDIT: In response to your comment: If you have multiple select boxes that you need ID's for, you can implement a class based solution:
<select id="your_id_here1" class="formSelect" />
<select id="your_id_here2" class="formSelect" />
$(document)ready(function() {
$('body').on('change', '.formSelect', function() {
var elementID = this.id;
alert(elementID);
});
});
With this solution, any select box with a .formSelect class will have the change event bound to it and the ID of the particular input element changed will be displayed in the alert box.

You can try this solution below.
Note that a full working example can be found at the end of this post.
Set the method method attribute of your <form> to GET or POST, and define its method attribute (= which specifies where to send the form's data)
Add an ID to each of your "Answer" checkboxes. You can provide them the following IDs, respectively: R1, R2, R3, R4, and R5. Provide different names to each input.
Disable your "Answer" checkboxes by adding the attribute disabled. Since you only want the responses to check / uncheck the checkboxes, we want to prevent the users from doing it.
Eg:
<input type="radio" value="1" name="R1" id="R1" disabled>
Add an the following events to each of your "Answer" text inputs:
onkeyup="toggle_checkbox(this, i);", where i should be the index related to the ID of the checkbox concerned (check the example below). The toggle_checkbox function is called every time we type something inside an "Answer" textbox, and checks, or unchecks, the checkbox associated to the text input we're typing in, depending on the latter's content:
if the content of the texbox is empty, the function unchecks the checkbox,
else, it checks it.
ondragstart="return false" which prevents to copy the content from a given textbox to another.
Eg:
<td width="161">
<input type="text" name="cb1" size="20" style="width:300px;" maxlength="100"
onkeyup="toggle_checkbox(this, 1);" ondragstart="return false"></td>
<td>
<input type="radio" value="1" name="R1" id="R1" disabled>
Answer
</td>
In the example above, i is equal to 1, which is related to the concerned checkbox's ID R1.
In your <head>, add the following JS functions:
function toggle_checkbox(el, index) {
var val = el.value;
if(val!="") {
document.getElementById("R"+index).checked = "checked";
}
else {
document.getElementById("R"+index).checked = "";
}
}
function validate() {
var isok = false;
var nb_checked = 0;
for(var i =1; i<6; i++) {
var el = document.getElementById("R"+i);
if(el.checked) {
nb_checked++;
}
}
if(nb_checked < 3) {
alert("Enter at least 3 responses!");
}
else {
isok = true;
}
return isok;
}
As you can see, there are two functions: one is toggle_checkbox and the other is validate.
As explained a little bit previously, the function toggle_checkbox is called every time we type something inside an "Answer" textbox. This checks / unchecks the associated checkbox according to whether the content of the corresponding textbox is empty or not.
The function validate is called when we submit the form. It counts the number of "Answer" checkboxes which are checked with the variable nb_checked. If this number is lower than 3, then we alert the message Enter at least 3 responses!. Otherwise, we set the output variable isok to true, which will allow the form to be processed and sent to the link provided in the action attribute of the <form>
Full working example:
<!DOCTYPE html>
<html>
<head>
<script>
function toggle_checkbox(el, index) {
var val = el.value;
if(val!="")
document.getElementById("R"+index).checked = "checked";
else document.getElementById("R"+index).checked = "";
}
function validate() {
var isok = false;
var nb_checked = 0;
for(var i =1; i<6; i++) {
var el = document.getElementById("R"+i);
if(el.checked)
nb_checked++;
}
if(nb_checked < 3) alert("Enter at least 3 responses!");
else
isok = true;
return isok;
}
</script>
<head>

PS: Change the action attribute of the form. I set google's url just to let you see the redirection when the form is valid.
Hope this helps. Let me know if you have any questions.
