this code for auto calculation for multiple choice quiz. only option "A" is correct for each 5 question other all options is incorrect. here is my requirements.
when user clicks on only option "correct" for any question number it adds point 1 to the total.
when user clicks on only option "incorrect" for any question will add point -1 to the total.
when user clicks on both option "correct" and "incorrect" for any question number it adds point -1 to the total. for example user clicks all checkbox for question 1 it should add only -1 to the total (in example above it is -2 which is = 1-1-1-1.) ie. if a user checked all the checkbox in the above example it will get total:-10. But my requirement is to show only -5. ie = -1-1-1-1-1.
thanks in advance..
I have created a fiddle for you at http://jsfiddle.net/DYduY/ It isn't the nicest solution but what I do is calculate the total per row. If it is lower than -1 e.g. -2 than I change the row value to -1. In this way the maximal negative value for a row is -1.
$(document).ready(function() {
$("input[type=checkbox]").click(function() {
var total = 0;
$("tr").each(function() {
var rowTotal = 0;
$(this).find("input[type=checkbox]:checked").each(
function() {
rowTotal += parseInt($(this).val());
});
if (rowTotal < -1) { rowTotal = -1 }
total += rowTotal;
});
$("#total").html("tatal:" + total);
});
});
Got it more improve solution. Here is the jquery code.
$(document).ready(function() {
$("input[type=checkbox]").click(function() {
var total = 0;
$("tr").each(function() {
var checked = $(this).find( "input:checked").length;
var values = $(this).find( "input[type=checkbox]").map(function() {
return parseInt($(this).val());
}).get();
var minimum = Math.min.apply( this, values );
var rowTotal = 0;
$(this).find("input[type=checkbox]:checked").each(
function() {
rowTotal += parseInt($(this).val());
});
if (checked > 1) { rowTotal = minimum }
total += rowTotal;
});
$("#total").html("tatal:" + total);
});
});

I'm working on a simple table that generates number of checkbox, and count the total of how many are checked.
when I unchecked, it will show how many are the remaining checked checkbox.
my problem is when I generate new rows the counter doesn't work anymore.
$('.items').keyup(function() {
var items = $(this).val();
$('span').text(items);
$('table tbody tr').remove();
for (var i = 1; i <= items; i++) {
$('table > tbody').append('<tr><td><input type="checkbox" checked></td></tr>');
}
});
$('input:checkbox').click(function() {
var count = $(this).closest('table').find('input:checkbox:checked').length;
$('span').text(count);
});

Use event delegation instead, so that you only need to apply a single listener to the container, otherwise you'll have to re-add listeners to each element every time:
$('.items').keyup(function() {
var items = $(this).val();
$('span').text(items);
$('table tbody tr').remove();
for (var i = 1; i <= items; i++) {
$('table > tbody').append('<tr><td><input type="checkbox" checked></td></tr>');
}
});
$('table').on('click', 'input', function() {
var count = $(this).closest('table').find('input:checkbox:checked').length;
$('span').text(count);
});

I'm trying to use/adapt an existing script to show/hide a hierarchical series of radio buttons, based on selection. Please see the code below. The problem is that the 2nd-level radio button disappears when a selection is made for the 3rd-level radio button. It seems that the culprit is, $(".opthide").not(targetBox).hide(); but I'm unsure how to restrict hiding to related elements.
$(document).ready(function() {
$('input[name="insv_sts5"]').click(function() {
var inputValue = $(this).attr("value");
var targetBox = $("." + inputValue);
$(".opthide").not(targetBox).hide();
$(targetBox).show();
});
});
$(document).ready(function() {
$('input[name="insv_sts6"]').click(function() {
var inputValue = $(this).attr("value");
var targetBox = $("." + inputValue);
$(".opthide").not(targetBox).hide();
$(targetBox).show();
});
});
$(document).ready(function() {
$('input[name="insv_sts9"]').click(function() {
var inputValue = $(this).attr("value");
var targetBox = $("." + inputValue);
$(".opthide").not(targetBox).hide();
$(targetBox).show();
});
});
.opthide {
display: none;

welcome to SO,
Here are my 2 cents.
I made loop go through all radio buttons on click and act appropriately if the button is checked it shows target element, if it is not it clears checks on lower-level buttons and hide the element, this is needed to prevent elements showing even if a user changes mind and change some top-level checkbox.
Hope it helps, if you would have any questions or anyone would have different approach let me know.
Final would look like this.
$(document).ready(function() {
$('input[type="radio"]').click(function() {
$('input[type="radio"]').each(function () {
//iterate through all radio buttons
var $target = $(this).val() //get target class from value
if ($(this).prop('checked')) { //check if radio box is checked
$('.' + $target).show() //show target tr
} else {
//hide target tr and uncheck all radio buttons in child element
$('.' + $target).hide().find('input[type="radio"]').prop('checked', false);
}
})
});
});

display: none;

I have an issue with my code. How to substract checkbox value when combobox change. I hope anybody here can help me.
Here is my js code:
//javascript for adding checkbox value and display in text.
<script>
$(document).ready(function(){
$('input[type=checkbox]').click(function(e){
$('#txtInput').val($(this).val())
var total = 0;
var text;
$("input[type=checkbox]:checked").each(function(i,ch) {
total += parseFloat($(this).val());
});
$("#txtInput").val(total);
});
});
</script>
//javascript for substract checkbox value when combobox change
<script>
$(document).ready(function(){
$('.xyz').change(function(){
var tmp = $(this).closest('tr').find("input[type='checkbox']").attr('id');
var substract = 0;
$('#'+tmp+'').prop("checked",false)+(substract -= parseFloat($('#'+tmp+'').val()));
$("#txtInput").val(substract);
});
});
And here is my HTML code:
<table>
<tr>
<th>SELECTION</th>
<th>ACTION</th>
<th>FOOD NAME</th>
</tr>
<tr>
<td><select class="xyz" name="xyz1" id="xyz1"><option >Cancel</option>
<option>Take</option></select></td>
<td><input type="checkbox" name="check1" id="check1" value="1" /></td>
<td>French Fries</td>
</tr>
<tr>
<td><select class="xyz" name="xyz2" id="xyz2"><option >Cancel</option>
<option>Take</option></select></td>
<td><input type="checkbox" name="check2" id="check2" value="3" /></td>
<td>Pizza</td>
</tr>
<tr>
<td><select class="xyz" name="xyz3" id="xyz3"><option >Cancel</option>
<option>Take</option></select></td>
<td><input type="checkbox" name="check3" id="check3" value="5" /></td>
<td>Beef Burger</td>
</tr>
</table>
<input type="text" name="txtInput" id="txtInput" />
First, if I select "Take" in combobox and click checkbox the value will be shown into text.
Second, if I do it again the checkbox will be add the value and show the result into text.
Third, this my problem. If I change combobox into "Cancel" the checkbox only uncheck but can't decrease the value. I want if I change combobox into "Cancel" the value decrease according checkbox selection value and checkbox uncheck.
For any help, I really appreciate it. Thanks.
Make a common function which will read the state of the input elements and do the calculations accordingly.
.parents(selector) will traverse up and will returned matched element.
Try this:
var doCalc = function() {
var total = 0;
var text;
$("input[type=checkbox]:checked").each(function(i, ch) {
if ($(this).parents('tr').find('select option:selected').text() == 'Take') {
total += parseFloat($(this).val());
}
});
$("#txtInput").val(total);
}
$('input[type=checkbox]').change(doCalc);
$('.xyz').change(function() {
if ($(this).find('option:selected').text() == 'Cancel') {
$(this).parents('tr').find('input[type="checkbox"]').prop('checked', false);
}
doCalc();
});

Fiddle here
I have six columns with six checkboxes (or radio).
My intention is, that only one checkbox can be selected in the same row and the same column.
For example:
When I select the checkbox in column4 and row3', every checkbox in row3 and column4 have to be unselected immediately.
I tried it with radio buttons, but I simply can´t do it, because every single radio always to be in two different groups.

<input type="checkbox" />
<input type="checkbox" />
</div>
jquery
$('input[type="checkbox"]').on('change', function() {
// uncheck sibling checkboxes (checkboxes on the same row)
$(this).siblings().prop('checked', false);
// uncheck checkboxes in the same column
$('div').find('input[type="checkbox"]:eq(' + $(this).index() + ')').not(this).prop('checked', false);
});
Here's a fiddle
Here's another example using classes
I'm not sure if this is the best possible solution, but I think it does what you want.
$(":radio").change(function() {
// find column
var tdColumn = $(this).closest("td");
// find row
var trRow = tdColumn.closest("tr");
// uncheck all radios in current row, except the selected radio
trRow.find(":radio").not($(this)).prop("checked",false);
// index of current column
var i = tdColumn.index();
// uncheck all radios in current column, except the selected radio
trRow.siblings("tr").each(function(key, value) { $(value).find(":radio")[i].checked = false; } );
});

I created it by 3 columns and 5 rows BUT it works for N cols and M rows... just increase td and tr tags...
Try this...
Also you can test it live here ;)
Result

jQuery:
$(document).ready(function(){
var $table = $('#MyTable');
var $rowCount = $table.find('tr').length;
var $colCount = $($table.find('tr')[0]).find('td').length;
console.log($rowCount);
console.log($colCount);
$table.find('tr').each(function(i, e){
$tr=$(e);
console.log($tr);
});
});
$(".chBox").click(function() {
console.log('clicked');
$this=$(this);
$row=$this.parent().parent();
$table=$this.closest('table');
$row.find('.chBox').each(function(i, e){
$checkbox=$(e);
$checkbox.prop('checked',false);
console.log($checkbox);
});
$this.prop('checked',true);
var col = $this.parent().parent().children().index($this.parent());
var row = $this.parent().parent().parent().children().index($this.parent().parent());
console.log(col);

Select only one checkbox/radiobutton in the same row and column with Angular 7 and JavaScript
The Idea behind this is that with radio button we have name property which makes single select either by row or column but for both row and column. I placed the row in name and handled column with javascript whenever button will click.
This is HTML CODE
<section class="editor">
<strong>Editor</strong>
<div>
<label>Add option</label>
<button (click)="addOption()">+</button>
<div *ngFor="let option of options;let i = index">
<span>{{option.title +(i+1)}}</span><button (click)="deleteOption(i)"
*ngIf="options.length>2">X</button>
</div>
</div>
</section>
<hr>
<section>
<strong>Builder</strong>
<div class="builder">
<label>Question title goes here</label><br>
<div *ngFor="let option of options;let row_index = index">
<span>{{option.title +(row_index+1)}}</span>
<span *ngFor="let rank of options;let column_index=index">
<input type="radio" name="{{row_index}}" class="{{column_index}}"
(click)="check(column_index,$event)">
</span>
</div>
</div>
</section>
And this is my .ts file code where I Implemented with Javascript
export class AppComponent {
options = [{
title: "option",
rank: 0,
}, {
title: "option",
rank: 0
}]
constructor() {
}
ngOnInit(): void { }
addOption() {
this.options.push({
title: "option",
rank: 0
})
}
deleteOption(i) {
this.options.splice(i, 1);
}
check(column_index, event) {
Array.from(document.getElementsByClassName(column_index)).map(x=>x['checked']=false);
event.target.checked=true;
}
}
My task is what I have done but I am wondering about if the select box is not only three options... If they are 5 or 10 options so let's imagine that how the if else condition below can be...
More than that, after choosing another option, the others option's input will be returned to no value as my code.
Demo
HTML:
<table>
<tr><td>123</td></tr>
<tr><td>456</td></tr>
<tr><td>...</td></tr>
<tr>
<td>
<select id="select_vehicle">
<option value="company_vehicle">Company Vehicle</option>
<option value="hiring_vehicle">Hiring Vehicle</option>
<option value="taxi">Taxi</option>
</select>
</td>
</tr>
<tr id="company_vehicle">
<td>Company Vehicle</td>
<td>
<input type="text" />
</td>
<td>
<input type="radio" name="vehicle" value="bus" />Bus</td>
<td>
<input type="radio" name="vehicle" value="train" />Trolley Car</td>
</tr>
<tr id="hiring_vehicle">
<td>Hiring Vehicle</td>
<td>
<input type="radio" name="vehicle" value="bus" />Bus</td>
<td>
<input type="radio" name="vehicle" value="train" />Trolley Car</td>
<td>
<input type="text" />
</td>
</tr>
<tr id="taxi">
<td>Taxi</td>
<td>
<input type="checkbox" name="vehicle" value="Taxi" />Taxi
</td>
</tr>
<tr><td>...</td></tr>
<tr><td>123</td></tr>
<tr><td>456</td></tr>
</table>
Javascript:
var select_vehicle = $("#select_vehicle");
// Set selected item
var set_selected_item = $(select_vehicle).val("company_vehicle");
// Hide options "Hiring Vehicle" & "Taxi"
var company_vehicle = $("#company_vehicle"); // Get id "Company Vehicle"
var hiring_vehicle = $("#hiring_vehicle"); // Get id "Hiring Vehicle"
hiring_vehicle.hide();
var taxi = $("#taxi"); // Get id "Taxi"
taxi.hide();
$(select_vehicle).on('change', function (e) {
var optionSelected = $("option:selected", this);
var valueSelected = this.value;
if (valueSelected == "company_vehicle") {
company_vehicle.show();
hiring_vehicle.hide();
taxi.hide();
$("#taxi input").removeAttr('checked');
$("#hiring_vehicle input").removeAttr('checked').val("");
} else if (valueSelected == "hiring_vehicle") {
company_vehicle.hide();
hiring_vehicle.show();
taxi.hide();
$("#company_vehicle input").removeAttr('checked').val("");
$("#taxi input").removeAttr('checked');
} else {
company_vehicle.hide();
hiring_vehicle.hide();
taxi.show();
$("#company_vehicle input").removeAttr('checked').val("");
$("#hiring_vehicle input").removeAttr('checked').val("");
}
});
You can do:
$('#select_vehicle').change(function() {
var val = this.value;
$('#'+val).find('input[type="text"]').val('');
$('#'+val).find('input[type="radio"]').prop('checked',false);
$('#'+val).show().siblings('tr[id]').hide();
}).change();
Updated Fiddle
You can use the value of $("#select_vehicle") to dynamically get the id of the element to show. In the HTML add the class select_option to all of the tr's that are option holders like:
<tr id="company_vehicle" class="select_option">
<td>Company Vehicle</td>
<td>
<input type="text" />
</td>
<td>
<input type="radio" name="vehicle" value="bus" />Bus</td>
<td>
<input type="radio" name="vehicle" value="train" />Trolley Car</td>
</tr>
<tr id="hiring_vehicle" class="select_option">
<td>Hiring Vehicle</td>
<td>
<input type="radio" name="vehicle" value="bus" />Bus</td>
<td>
<input type="radio" name="vehicle" value="train" />Trolley Car</td>
<td>
<input type="text" />
</td>
</tr>
<tr id="taxi" class="select_option">
<td>Taxi</td>
<td>
<input type="checkbox" name="vehicle" value="Taxi" />Taxi</td>
</tr>
Javscipt:
$("#select_vehicle").on('change', function(){
var optionSelected = $("option:selected", this);
var valueSelected = this.value;
$('.select_option').hide();
$('.select_option input[type="text"]').val('');
$('.select_option input:checked').prop('checked', false);
$('#'+valueSelected).show();
}).trigger('change');
