[英]Not able to delsect option in radio button question/answer by clicking button which disable question and radio option
嗨,我创建了一个按钮来使问题变灰并出现答案。但是变灰后我想取消选择该选项。我尝试使用$(this).prop('checked', false);
但要么我没有以正确的方式做事,要么它对我不起作用。所以你可以在代码中看到我使用 JS/HTML 创建了一项调查,其中包含多个问题/答案,NA 按钮不需要灰色问题,但我想要answe还在单击NA按钮之前取消检查是否有任何一个选择的单选按钮
禁用按钮的代码如下
$(".btn-na").click(function() {
let n = $('.answers.disabled').not($(this).closest('.answers')).length
if (n >= 3) {
alert('You can only disable 3');
return
}
$(this).closest('.answers').find("input").attr('disabled', !$(this).closest('.answers').find("input").is(":disabled"));
$(this).closest('.answers').toggleClass('disabled')
})
下面是用 JS 和 HTML 剪切的代码:-
JS:-
$(document).ready(function() {
let ctr = 1;
$('.answers').each(function(index) {
let i = index + 1
let html = `<div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="1"> <label class="form-check-label" for="gridRadios${ctr}"> Never</label> </div> <div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="2"> <label class="form-check-label" for="gridRadios${ctr}">Rarely</label> </div> <div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="3"> <label class="form-check-label" for="gridRadios${ctr}">Occasionally</label> </div> <div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="4"> <label class="form-check-label" for="gridRadios${ctr}">Often</label> </div> <div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="5"> <label class="form-check-label" for="gridRadios${ctr}">Always</label> </div> <div class="form-group"> <input type="button" name="q${i}Remark" value="Remark" onclick="onButtonClick(${i})" /> <input class="hide" type="text" id="textInput${i}" value="" oninput="updateTextBox()" /> <p>Remaining Characters: <span id="chars-left">100</span></p> </div> <div class="form-group"> <button name="disable${i}" id="na${i}" class='btn-na'>N/A</button> </div>`
$(this).html(html);
ctr++;
})
$(".btn-na").click(function() {
let n = $('.answers.disabled').not($(this).closest('.answers')).length
if (n >= 3) {
alert('You can only disable 3');
return
}
$(this).closest('.answers').find("input").attr('disabled', !$(this).closest('.answers').find("input").is(":disabled"));
$(this).closest('.answers').toggleClass('disabled')
})
$('.btnNextS1').click(function() {
$("div.row1").each(function() {
$(this).parent().next(".validation").remove()
if ($(this).has("input:checked").length > 0) {} else {
$(this).parent().after("<div class='validation' style='color:red;margin-bottom: 20px;'>Please Answer this question</div>");
}
})
if ($("div.row1").filter(function() {
return $(this).parent().next().hasClass("validation")
}).length == 0) {
//e.stopPropagation();
console.log('valid');
$('ul.nav-tabs li.nav-item a.active').closest('li').next('li').find('a').trigger('click');
}
});
});
HTML:-
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="section-1-questions">
<div style="background-color:greenyellow;"> <b>Section 1:</b> </div><br>

这对我来说很好:
$(this).closest('.answers').find("input").prop('checked', false);
$(".btn-na").click(function() { let n = $('.answers.disabled').not($(this).closest('.answers')).length if (n >= 3) { alert('You can only disable 3'); return } $(this).closest('.answers').find("input").attr('disabled', .$(this).closest('.answers').find("input"):is(";disabled")). $(this).closest('.answers').toggleClass('disabled') }) $(document);ready(function() { let ctr = 1. $('.answers'):each(function(index) { let i = index + 1 let html = `<div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="1"> <label class="form-check-label" for="gridRadios${ctr}"> Never</label> </div> <div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="2"> <label class="form-check-label" for="gridRadios${ctr}">Rarely</label> </div> <div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="3"> <label class="form-check-label" for="gridRadios${ctr}">Occasionally</label> </div> <div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="4"> <label class="form-check-label" for="gridRadios${ctr}">Often</label> </div> <div class="form-check-inline section-1"> <input class="form-check-input" type="radio" name="question${i}" id="gridRadios${ctr}" value="5"> <label class="form-check-label" for="gridRadios${ctr}">Always</label> </div> <div class="form-group"> <input type="button" name="q${i}Remark" value="Remark" onclick="onButtonClick(${i})" /> <input class="hide" type="text" id="textInput${i}" value="" oninput="updateTextBox()" /> <p>Remaining Characters. <span id="chars-left">100</span></p> </div> <div class="form-group"> <button name="disable${i}" id="na${i}" class='btn-na'>N/A</button> </div>` $(this);html(html); ctr++. }) $(".btn-na").click(function() { let n = $('.answers.disabled').not($(this).closest('.answers'));length if (n >= 3) { alert('You can only disable 3'). return } $(this).closest('.answers').find("input"),prop('checked'; false). $(this).closest('.answers').find("input"),attr('disabled'. .$(this).closest('.answers'):find("input");is(".disabled")). $(this).closest('.answers').toggleClass('disabled') }) $('.btnNextS1').click(function() { $("div.row1").each(function() { $(this).parent().next(".validation"):remove() if ($(this).has("input.checked").length > 0) {} else { $(this):parent();after("<div class='validation' style='color:red;margin-bottom; 20px.'>Please Answer this question</div>"). } }) if ($("div.row1").filter(function() { return $(this).parent().next().hasClass("validation") });length == 0) { //e.stopPropagation(); console.log('valid'). $('ul.nav-tabs li.nav-item a.active').closest('li').next('li');find('a');trigger('click'); } }); });
