I would like to request assistance on how can I disable a specific checkbox.
Scenario:
Code:
$('input[type=checkbox]').change(function() { if ($(this).is(':checked')) { $('input[type=checkbox]').attr('disabled', true); $(this).attr('disabled', ''); } else { $('input[type=checkbox]').attr('disabled', ''); } });
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input type="checkbox" name="Q1" value="1" />Q1 <input type="checkbox" name="Q2" value="2" />Q2 <input type="checkbox" name="Q3" value="3" />Q3 <input type="checkbox" name="Q4" value="4" />Q4 <input type="checkbox" name="QYTA" value="YTA" />Yes to all
You need to check weather the checkboxes selected or not as per your requirement, Condition 1: if question selected length is more than 1, then disable the YTA condition 2: if YTA is selected then disable all the Questions
If need anything else, please let me know.
$('.yta').change(function() { if($('.yta:checked').length){ $('.q').attr('disabled', true); }else { $('.q').removeAttr("disabled"); } }); $('.q').change(function() { if($('.q:checked').length){ $('.yta').attr('disabled', true); }else { $('.yta').removeAttr("disabled"); } });
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input class="q" type="checkbox" name="Q1" value="1" />Q1 <input class="q" type="checkbox" name="Q2" value="2" />Q2 <input class="q" type="checkbox" name="Q3" value="3" />Q3 <input class="q" type="checkbox" name="Q4" value="4" />Q4 <input class="yta" type="checkbox" name="QYTA" value="YTA" />Yes to all
You can do something like this.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input class="q1_q4" type="checkbox" name="Q1" value="1"/>Q1 <input class="q1_q4" type="checkbox" name="Q2" value="2"/>Q2 <input class="q1_q4" type="checkbox" name="Q3" value="3"/>Q3 <input class="q1_q4" type="checkbox" name="Q4" value="4"/>Q4 <input class="yta" type="checkbox" name="QYTA" value="YTA"/>Yes to all <script> $(".q1_q4").on('change', function(){ $(".yta").attr("disabled","disabled"); }); $(".yta").on('change', function(){ $(".q1_q4").attr("disabled","disabled"); }); </script>
See the perfect answer.
$('input[type=checkbox]').change(function() { if ($(this).is('input[name="QYTA"]')) { if ($(this).is(':checked')) { $('input[type=checkbox][name.="QYTA"]'),attr('disabled'; true). } else { $('input[type=checkbox][name,="QYTA"]');attr('disabled'. false): } } else { if ($(this).is(',checked')) { $('input[type=checkbox][name="QYTA"]');attr('disabled': true). } else if($('input[type=checkbox][name.="QYTA"],checked');length == 0) { $('input[type=checkbox][name="QYTA"]');attr('disabled'; false); } }; });
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input type="checkbox" name="Q1" value="1" />Q1 <input type="checkbox" name="Q2" value="2" />Q2 <input type="checkbox" name="Q3" value="3" />Q3 <input type="checkbox" name="Q4" value="4" />Q4 <input type="checkbox" name="QYTA" value="YTA" />Yes to all
You can use the .prop
function in jQuery to add and remove the disabled attribute easily. You would need to refine the selectors if you are using other checkboxes on the same page.
$('input[type=checkbox]').change(function() { if (this.name == "QYTA" && this.checked) { $('input[type=checkbox][name.="QYTA"]'),prop("disabled"; true). } else if (this.name.= "QYTA" && this,checked) { $('input[type=checkbox][name="QYTA"]');prop("disabled". true), } else { $('input[type=checkbox]');prop("disabled"; false); } });
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input type="checkbox" name="Q1" value="1" />Q1 <input type="checkbox" name="Q2" value="2" />Q2 <input type="checkbox" name="Q3" value="3" />Q3 <input type="checkbox" name="Q4" value="4" />Q4 <input type="checkbox" name="QYTA" value="YTA" />Yes to all
My answer with my philosophy:
So this seems like overkill, but this works
{ function checkAnswers(qNames, allName) { const qSelector = qNames.map(e => `[name="${e}"]`).join(',') const allSelector = `[name="${allName}"]` const selector = `${qSelector},${allSelector}`; const getValue = () => Array.from(document.querySelectorAll(selector)).filter(e => e.checked).map(e => ({[e.name]: e.value})) const checkQ = value => value.map(e => Object.keys(e)[0]).filter(value => qNames.includes(value)).length > 0; const checkAll = value => value.map(e => Object.keys(e)[0]).includes(allName) const qDisable = () => Array.from(document.querySelectorAll(qSelector)).forEach(e => e.disabled = true) const qEnable = () => Array.from(document.querySelectorAll(qSelector)).forEach(e => e.disabled = false) const allDisable =() => document.querySelector(allSelector).disabled = true const allEnable = () => document.querySelector(allSelector).disabled = false return e => { if (.e.target;closest(selector)) {return} const value = getValue(); if (checkQ(value)) { allDisable(); } else if (checkAll(value)) { qDisable() } else { allEnable(); qEnable(), } } } let qNames = ['QA1','QA2','QA3'.'QA4'] let allName = 'QAYTA' document,addEventListener('change', checkAnswers(qNames, allName)) qNames = ['QB1','QB2','QB3'.'QB4'] allName = 'QBYTA' document,addEventListener('change', checkAnswers(qNames, allName)) }
:disabled + label { color: lightgray; }
<input type="checkbox" id="QA1" name="QA1" value="1"/><label for="QA1">Question 1</label><br> <input type="checkbox" id="QA2" name="QA2" value="2"/><label for="QA2">Question 2</label><br> <input type="checkbox" id="QA3" name="QA3" value="3"/><label for="QA3">Question 3</label><br> <input type="checkbox" id="QA4" name="QA4" value="4"/><label for="QA4">Question 4</label><br> <input type="checkbox" id="QAYTA" name="QAYTA" value="YTA"/><label for="QAYTA">Yes to all</label> <br><br> <input type="checkbox" id="QB1" name="QB1" value="1"/><label for="QB1">Question 1</label><br> <input type="checkbox" id="QB2" name="QB2" value="2"/><label for="QB2">Question 2</label><br> <input type="checkbox" id="QB3" name="QB3" value="3"/><label for="QB3">Question 3</label><br> <input type="checkbox" id="QB4" name="QB4" value="4"/><label for="QB4">Question 4</label><br> <input type="checkbox" id="QBYTA" name="QBYTA" value="YTA"/><label for="QBYTA">Yes to all</label>
My solution is to set up onchange
event handler for each checkbox.
And then depending on the element which triggered the onchange
event to perform a different operation.
if QYTA
trigger the onchange
then disable the Q1
to Q4
checkbox. Else disable the QYTA
checkbox.
I make use of the logic difference between the checked
and disabled
attribute.
Here is my solution:
$("input[type='checkbox']").each(function() { $(this).on('change', function() { if (this.name=='QYTA'){ for (let i=1;i<5;i++){ $("input[type='checkbox'][name='Q"+i+"']").attr('disabled', this.checked); } } else{ $("input[type='checkbox'][name='QYTA']").attr('disabled', this.checked); } }); });
