jquery .prop('disabled', true) not working - javascript

I am attempting to toggle disabled = true|false on a <input type="text">, using a checkbox. I am able to get the value of the input, but I cannot set the input to disabled.
my jquery/js code
<script>
$(function () {
$('.date').datepicker();
$('body').on('change', '.housing', function () {
if ($(this).val() == 'dorms') {
$(this).parent().next(".dorms").show();
} else {
$(this).parent().siblings(".dorms").hide();
}
});
$('body').on('change', '.single', function () {
if ($(this).checked) {
$('#echo1').text($(this).prev(".roommate").val()); // this works
$(this).prev(".roommate").val(''); // does not empty the input
$(this).prev(".roommate").disabled = true; // does not set to disabled
$(this).prev(".roommate").prop('disabled', true); // does not set to disabled
$('#echo2').text($(this).prev(".roommate").prop('disabled')); // always says false
} else {
$('#echo1').text($(this).prev(".roommate").val()); // this works
$(this).prev(".roommate").disabled = false; // always stays false
$('#echo2').text($(this).prev(".roommate").prop('disabled')); // always says false
}
});
});
</script>
my html code
<div class="registration_housing particpant_0" data-sync="0">
<div>
<label class="particpant_0"></label>
</div>
<div>
<label>Off Campus (not included)</label>
<input type="radio" name="housing[0]" value="none" class="housing" />
</div>
<div>
<label>On Campus</label>
<input type="radio" name="housing[0]" value="dorms" class="housing" />
</div>
<div class="dorms" style="display:none;">
<div>
<label>Checkin:</label>
<input type="text" name="check_in[0]" class="date" />
</div>
<div>
<label>Checkout:</label>
<input type="text" name="check_out[0]" class="date" />
</div>
<div>
<label>Roommate:</label>
<input type="text" name="roommate[0]" class="roommate" />
<input type="checkbox" name="roommate_single[0]" value="single" class="single" />check for singe-occupancy</div>
</div>
<div class="line">
<hr size="1" />
</div>
</div>
<div>
<label id="echo1"></label>
</div>
<div>
<label id="echo2"></label>
</div>
you can see this at http://jsfiddle.net/78dQE/1/
Any idea why I can get the value of (".roommate") - ie. $(this).prev(".roommate").val()
but
$(this).prev(".roommate").disabled = true;
OR
$(this).prev(".roommate").prop('disabled', true);
will not set (".roommate") to disabled?

Your issue is mixing jquery with DOM element attributes
change if ($(this).checked) { to if (this.checked) {
With jquery you would do
$(this).is(':checked') // But you could just do this.checked
And
$(this).prev(".roommate").prop('disabled', false); // or $(this).prev(".roommate")[0].disabled = false;
instead of
$(this).prev(".roommate").disabled = false;
Fiddle
So you just probably need this:
$('body').on('change', '.single', function () {
$(this).prev(".roommate").prop('disabled', this.checked).val('');
});

Checking to see if a checkbox is selected before searching

I am having some trouble with my checkboxes. I am trying to get a returned true or false value out of event listeners on checkboxes and then passing it through an event listener on a button to confirm that at least one checkbox is selected. I'm sorry if this sounds confusing and I feel like there is an easier way to do this. I would like to solve this with pure JavaScript. Really appreciate the help. Below is the code.
<body>
<script src="racquetObjects.js"></script>
<div class="mainContainer">
<div class="selectors">
<form action="">
<div class="checkboxes">
<input type="checkbox" id="babolat" value="Babolat" />
<label for="babolat">Babolat</label>
<input type="checkbox" id="wilson" value="Wilson" />
<label for="wilson">Wilson</label>
<input type="checkbox" id="power" value="Power" />
<label for="power">Power</label>
<input type="checkbox" id="control" value="Control" />
<label for="control">Control</label>
<input type="checkbox" id="popular" value="Popular" />
<label for="popular">Popular</label>
</div>
<button type="button" id="find">Find</button>
</form>
</div>
<div class="racquetContainer"></div>
<div class="bench"></div>
</div>
<script src="racquetFinderCB.js"></script>
<script src="racquetFinder.js"></script>
</body>
const findButton = document.querySelector("#find");
const checkboxes = document.querySelectorAll(
".checkboxes input[type=checkbox]"
);
const checkboxesAreChecked = checkboxes.forEach((el) => {
el.addEventListener("click", (e) => {
if (e.target.checked) {
return true;
} else {
return false;
}
});
});
const beforeSubmit = () => {
if (checkboxesAreChecked === true) {
console.log("Time to search!");
} else {`enter code here`
console.log("You need to select an option");
}
};
In this example there is an event listener for the form submit. An array of the input elements is filtered, so only the checked will end up in checked.
The first e.preventDefault() is just for testing. If the form should submit (something was checked) then remove that line of code.
document.forms.find.addEventListener('submit', e => {
let inputs = e.target.querySelectorAll('input');
e.preventDefault(); // prevent default to test what happens
let checked = [...inputs].filter(input => input.checked);
if (checked.length > 0) {
console.log('at least one was checked');
} else {
e.preventDefault(); // prevent default to stop the form action
console.log('none was checked');
}
});
<div class="mainContainer">
<div class="selectors">
<form name="find" action="">
<div class="checkboxes">
<input type="checkbox" id="babolat" value="Babolat" />
<label for="babolat">Babolat</label>
<input type="checkbox" id="wilson" value="Wilson" />
<label for="wilson">Wilson</label>
<input type="checkbox" id="power" value="Power" />
<label for="power">Power</label>
<input type="checkbox" id="control" value="Control" />
<label for="control">Control</label>
<input type="checkbox" id="popular" value="Popular" />
<label for="popular">Popular</label>

jQuery: How to uncheck random checkboxes in div after checking all?

When onClick on link occurs, all checkboxes present in that div are checked.
function initSelectAll() {
$("form").find("a.selectAll").click(function() {
var cb = $(this).closest("div").find("input[type=checkbox]");
cb.not(":checked").click().length || cb.click();
//........WANT TO UNCHECK checkboxes with class="file" where link id is 'id="ninapaya"'; how to do that?......
return false;
});
}
initSelectAll();
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form>
<div>
Select
<span class="kukapaya">(alle)</span>
<br>
<input type="checkbox" class="document" name="check2">
<input type="checkbox" class="document" name="check2">
<br>
<input type="checkbox" class="File">
<input type="checkbox" class="File">
</div>
</form>
Requirement: We should not check the checkboxes with class="File".
JSFiddle: https://jsfiddle.net/k4d6zpay/
It could be simplified using .prop(.prop( propertyName, function )) and using :not selector
$("form").find("a.selectAll").click(function() {
$(this).closest("div").find("input[type='checkbox']:not('.File')").prop('checked', function() {
return !this.checked;
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<form>
<div>
Select
<span class="kukapaya">(alle)</span>
<br>
<input type="checkbox" class="document" name="check2">
<input type="checkbox" class="document" name="check2">
<br>
<input type="checkbox" class="File">
<input type="checkbox" class="File">
</div>
</form>
try this:
function initSelectAll() {
$("form").find("a.selectAll").click(function() {
var cb = $(this).closest("div").find("input[type=checkbox]");
cb.not(":checked").not('.File').click().length || cb.click();
return false;
});
}
initSelectAll();
Also update in your jsfiddle link: https://jsfiddle.net/k4d6zpay/1/
function initSelectAll() {
$("form").find("a.selectAll").click(function() {
var cb = $(this).closest("div").find("input[type=checkbox]:not(.File)");
cb.not(":checked").click().length || cb.click();
//........WANT TO UNCHECK checkboxes with class="file" where link id is 'id="ninapaya"';
$(this).closest("div").find("input[type=checkbox][id='ninapaya'].File").prop('checked',false);
return false;
});
}
initSelectAll();

How to show form fields on keyup

I've been working on this for weeks now and I can't seem to get the hang of this. I'm trying to show the hidden fields only when the previous fields are entered. Here's my example code:
HTML
<form>
<div id="group1">
<label>Field 1:</label>
<input type="text" class="field1" />
<br/>
<label>Field 2:</label>
<input type="text" class="field2" />
<br/>
<label>Field 3:</label>
<input type="text" class="field3" />
<br/>
</div>
<div id="group2">
<label>Field 4:</label>
<input type="text" class="field4" />
<br/>
<label>Field 5:</label>
<input type="text" class="field5" />
<br/>
<label>Field 6:</label>
<input type="text" class="field6" />
<br/>
</div>
<div id="group3">
<label>Field 7:</label>
<input type="text" class="field7" />
<br/>
<label>Field 8:</label>
<input type="text" class="field8" />
<br/>
<label>Field 9:</label>
<input type="text" class="field9" />
<br/>
<input type="submit" value="Submit">
</div>
</form>
CSS
#group2 {
visibility: hidden;
}
#group3 {
visibility: hidden;
}
Script
$(document).ready(function () {
$('#group1').find('input[type="text"]').keyup(function () {
CheckSubmit();
});
function CheckSubmit() {
var x = true;
$('#group1').find('input[type="text"]').keyup(function () {
if ($(this).val().length === 0) {
x = false;
return;
}
});
if (x) {
$('#group2').css('visibility', 'visible');
$('#group3').css('visibility', 'visible');
} else {
$('#group2').css('visibility', 'hidden');
$('#group3').css('visibility', 'hidden');
}
CheckSubmit();
});
I'm not sure what I'm doing wrong here. Can someone please assist?
I changed your code a bit. I stored the relevant selectors in variables, so you don't need to do a lot of re-querying every time something changes.
Here's the updated code:
JavaScript
var inputs = $('#group1').find('input[type="text"]');
var hidden = $('#group2, #group3');
inputs.keyup(function() {
var test = true;
inputs.each(function(key, value) {
if (!$(this).val().length) {
test = false;
return false;
}
});
hidden.css('visibility', ( test ? 'visible' : 'hidden' ) );
});
Demo
Try before buy
You can make this more dynamic by checking the inputs in the current div and if they all have a value, then show the next div (if there is one).
If they clear a value, then hide all the later divs.
$(document).ready(function() {
// you can restrict this to inputs in a specific div or just any input
$('#group1 input').on('keyup', function () {
var parentDiv = $(this).closest('div')
var hasValues = parentDiv.find('input').filter(function() {
return this.value == '';
}).length == 0;
if(hasValues) {
//parentDiv.next().css('visibility', 'visible'); // show just the next section
parentDiv.nextAll().css('visibility', 'visible'); // show all later sections
} else {
parentDiv.nextAll().css('visibility', 'hidden');
}
});
});
DEMO
I made a quick pen with a solution. It may not be the prettiest but it get's it done. Basically on every keyup event I check #group1's children for their value length and if they all have a length that's more than 0 I change a flag in an array. If all 3 flags are true I show #group2.
Here's the pen
$('#group2').hide();
$('#group3').hide();
$('#group1').keyup(function() {
var flags = {
0: false,
1: false,
2: false
}
$('#group1 > input').each(function(i, ele) {
if(ele.value.length !== 0)
{
flags[i] = true;
}
});
if(flags[0] && flags[1] && flags[2])
{
$('#group2').show();
}
});
$('#group2').keyup(function() {
var flags = {
0: false,
1: false,
2: false
}
$('#group2 > input').each(function(i, ele) {
if(ele.value.length !== 0)
{
flags[i] = true;
}
});
if(flags[0] && flags[1] && flags[2])
{
$('#group3').show();
}
});
Hope it helps :D
If I understand your question well, you want to show the fields in #group2/-3 if all the fields in the previous fields have a value. Using a few data-*-attributes (see MDN), you can create a handler like this (if you prefer: jsFiddle, containing a more complete example):
$('[data-nextgroup] [type=text]').on('keyup', function (e){
var fieldgroup = $(this.getAttribute('data-group'))
,fields = fieldgroup.find('[type=text]')
,canshow = fields.length ===
fields.filter( function (i,el) { return el.value.length; } ).length;
void( canshow && $(fieldgroup.attr('data-nextgroup')).fadeIn() );
});
[data-hidden] {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<div id="group1" data-nextgroup="#group2">
<label>Field 1:</label>
<input type="text" class="field1" data-group="#group1"/>
<br/>
<label>Field 2:</label>
<input type="text" class="field2" data-group="#group1"/>
<br/>
<label>Field 3:</label>
<input type="text" class="field3" data-group="#group1"/>
<br/>
</div>
<div id="group2" data-nextgroup="#group3" data-hidden>
<label>Field 4:</label>
<input type="text" class="field4" data-group="#group2"/>
<br/>
<label>Field 5:</label>
<input type="text" class="field5" data-group="#group2"/>
<br/>
<label>Field 6:</label>
<input type="text" class="field6" data-group="#group2"/>
<br/>
</div>
<div id="group3" data-groups data-hidden>
<label>Field 7:</label>
<input type="text" class="field7" />
<br/>
<label>Field 8:</label>
<input type="text" class="field8" />
<br/>
<label>Field 8:</label>
<input type="text" class="field9" />
<br/>
<input type="submit" value="Submit">
</div>

How do I enable a button when fields are filled in?

I'm trying to hide part of the form with the button disabled and have the user click on the button to show rest of form when previous fields are filled in. Can anyone help? Here's my code as an example:
HTML
<form>
<div id="group1">
<label>Field 1:</label>
<input type="text" class="field1"/><br/>
<label>Field 2:</label>
<input type="text" class="field2"/><br/>
<label>Field 3:</label>
<input type="text" class="field3"/><br/>
</div>
<div align="center">
<button id="show_form" onClick = "this.style.display= 'none'" disabled="disabled">
Enter Billing Info</button>
</div>
<div id="group2">
<label>Field 4:</label>
<input type="text" class="field4"/><br/>
<label>Field 5:</label>
<input type="text" class="field5"/><br/>
<label>Field 6:</label>
<input type="text" class="field6"/><br/>
</div>
</form>
JQUERY
<script>
$(document).ready(function () {
$('#group1').find('input[type="text"]').keyup(function () {
var flag = true;
$('#group1').find('input[type="text"]').each(function () {
if ($(this).val().length === 0) {
flag = false;
return;
}
});
if (flag) {
$("#show_form").prop("disabled", false);
} else {
$("#show_form").prop("disabled", true);
$("#group2").hide();
$("#show_form").show();
}
});
$("#group2").hide();
$("#show_form").click(function (){
$("#group2").show();
return false;
});
});
</script>
Try this jQuery:
$(document).ready(function () {
$('#group1').find('input[type="text"]').keyup(function () {
var flag = true;
$('#group1').find('input[type="text"]').each(function () {
if ($(this).val().length === 0) {
flag = false;
return;
}
});
if (flag) {
$("#show_form").prop("disabled", false);
} else {
/* This will hide the bottom form and disable the button again if
* any of the field above will be emptied.
* NOTE: This will just hide the form; it will not clear the fields.
*/
$("#show_form").prop("disabled", true);
$("#group2").hide();
}
});
$("#group2").hide();
$("#show_form").click(function (){
$("#group2").show();
return false;
});
});
This will enable the button when all the fields in the initial form are filled. Then the user will be able to click on the button to see the rest of the form.
You just need to loop through each input and check if a value is set when the button is clicked like this:
$('#show_form').click(function () {
var fields = $('.js-field');
var pass = true;
for (var i = 0; i < fields.length; i++) {
if (!$(fields[i]).val()) {
pass = false;
}
}
if (pass === true) {
$('#group2').show();
}
});
I also needed to add some classes to your html:
<form>
<div id="group1">
<label>Field 1:</label>
<input type="text" class="field1 js-field"/><br/>
<label>Field 2:</label>
<input type="text" class="field2 js-field"/><br/>
<label>Field 3:</label>
<input type="text" class="field3 js-field"/><br/>
</div>
<button type="button" id="show_form" value="Show_Form">Enter Billing
Info</button>
<div id="group2" style="display: none;">
<label>Field 4:</label>
<input type="text" class="field4"/><br/>
<label>Field 5:</label>
<input type="text" class="field5"/><br/>
<label>Field 6:</label>
<input type="text" class="field6"/><br/>
</div>
</form>
To see it in action visit this fiddle.
You can add some logic to the click event and check all the input fields to have a value like this
$("#show_form").click(function(){
var allFilled = true;
$('#group1').find('input').each(function(){
//if someone is empty allFilled will keep false
if(this.value === ''){
allFilled = false;
//this breaks the each
return false;
}
});
if(allFilled){
$("#group2").show();
}
});
Keep in mind the previous code only work with input fields.

Display Checkboxes on Click of a button

I have a button Resend , and on click of it , the checkboxes get enable against the following:
id="AlertSent"
id="AlertNotSent"
id="AlertInProgress"
Now the DIV Code for Above mentioned DIVS is as below
<div class="span9">
<div class="row-fluid">
<div id="enableCheckBox" class ="span12">
<input type="checkbox" id="checkbox1" name="checkbox1"/>
</div>
<div id="AlertSent" class="span12">
<label><spring:message code='alert.sent' />:</label>
</div>
</div>
<div class="row-fluid">
<div id="enableCheckBox" class ="span12">
<input type="checkbox" id="checkbox2" name="checkbox2"/>
</div>
<div id="AlertNotSent" class="span12">
<label><spring:message code='alert.not.sent'/>:</label>
</div>
</div>
<div class="row-fluid">
<div id="enableCheckBox" class ="span12">
<input type="checkbox" id="checkbox3" name="checkbox3" class="required" />
</div>
<div id="AlertInProgress" class="span12">
<label> <spring:message code='alert.in.progress' />:</label>
</div>
</div>
</div>
The button Code for Resend and Done is
<input type="button" value="button" id="resend"/>
<input type="button" value="button" id="done"/>
The JQuery Code is
var j$ = jQuery.noConflict();
j$(document).ready(function() {
var resendbtn = j$('#resend');
var allChkBox = j$('input[name="enableCheckBox"]');
var verifyChecked = function() {
if ! $('#resend').click {
allChkBox.attr('disabled', 'disabled');
} else {
allChkBox.removeAttr('disabled');
}
};
verifyChecked();
resendbtn.change(verifyChecked);
});
The requirement is on click of Resend, the checkboxes appear against above DIVS (AlertSent, AlertNotSent and AlertInProgress), and the Resend button Becomes Done, and if a User unchecks all the checkboxes then the Done Button becomes Resend again.
How do I write a JQuery/JavaScript code to achieve above?
Please suggest
It's hard to know exactly what you want here, but perhaps this will get you started:
http://jsfiddle.net/ZqH7B/
to handle showing the checkboxes:
$("#resend").on( 'click', function () {
$('.enableCheckBox').css('visibility', 'inherit');
$(this).hide().next().show();
$('input:checkbox').prop('checked', true);
});
to handle uncheck behavior:
$('input[type=checkbox]').on( 'change', function() {
var num = $('input:checked').length;
if ( num == 0 ) { $('#resend').show().next().hide(); }
});
Try following code:
HTML:
<input type="checkbox" class="chk">
<input type="button" value="Resend" class="toggle">
JS:
$(document).ready(function(){
$(".chk").prop("checked","checked");
$(".chk").css('display','none');
$(".toggle").click(function(){
$(".chk").css('display','block');
$(".chk").prop("checked","checked");
$(this).val("Done");
});
$(".chk").change(function(){
var all = $(".chk").length;
var chked = $(".chk").not(":checked").length;
if(all == chked){
$(".chk").css('display','none');
$(".toggle").val("Resend");
}
})
});
