How check and uncheck of a checkbox can show and hide a div

I have a checkbox with ID GlandularFever and on click (which checks it) I can get it to show another DIV with data-field name="GlandularDetails". Though on un-check, how do I get it to hide that div again? If data-field name="GlandularDetails hidden = true then show, else if data-field name="GlandularDetails hidden = false then hide.
<script>
$(document).ready(function(){
$("#GlandularFever").click(function(){
$(document.querySelectorAll('[data-field name="GlandularDetails"]')).show(100);
hidden = false;
});
});
</script>
<div class="col-md-12">
<div class="funkyradio">
<div class="funkyradio-primary col-md-4">
<input value="Yes" type="checkbox" name="GlandularFever" id="GlandularFever"/>
<label for="GlandularFever">Glandular Fever</label>
</div>
</div>
</div>
<div class="form-group col-md-12" data-field-name="GlandularDetails">
<label class="control-label">Details</label>
<textarea rows="3" id="GlandularDetails" name="GlandularDetails" maxlength="100" class="form-control" placeholder=""></textarea>
</div>
Thank you

Try this:
$(document).ready(function () {
$('#GlandularFever').click(function () {
if ($(this).prop('checked')) {
$('[data-field name="GlandularDetails"]').show(100);
} else {
$('[data-field name="GlandularDetails"]').hide(100);
}
});
});

You can use the JQuery method .toggle( [duration ] [, complete ] )
var glandularDetails = $('[data-field-name="GlandularDetails"]');
glandularDetails.hide();
$("#GlandularFever").click(function() {
glandularDetails.toggle(500);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="col-md-12">
<div class="funkyradio">
<div class="funkyradio-primary col-md-4">
<input value="Yes" type="checkbox" name="GlandularFever" id="GlandularFever" />
<label for="GlandularFever">Glandular Fever</label>
</div>
</div>
</div>
<div class="form-group col-md-12" data-field-name="GlandularDetails">
<label class="control-label">Details</label>
<textarea rows="3" id="GlandularDetails" name="GlandularDetails" maxlength="100" class="form-control" placeholder=""></textarea>
</div>

Use toggle to alternate between hidden and visible.
Also, avoid document.querySelectorAll when using jQuery. jQuery automatically handles that:
$("#GlandularFever").click(function() {
$('[data-field-name="GlandularDetails"]').toggle(100);
});
div.form-group {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="col-md-12">
<div class="funkyradio">
<div class="funkyradio-primary col-md-4">
<input value="Yes" type="checkbox" name="GlandularFever" id="GlandularFever" />
<label for="GlandularFever">Glandular Fever</label>
</div>
</div>
</div>
<div class="form-group col-md-12" data-field-name="GlandularDetails">
<label class="control-label">Details</label>
<textarea rows="3" id="GlandularDetails" name="GlandularDetails" maxlength="100" class="form-control" placeholder=""></textarea>
</div>

check this code and run
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("div[data-field-name=GlandularDetails]").hide();
$("#GlandularFever").click(function(){
if($(this).is(':checked'))
{
$("div[data-field-name=GlandularDetails]").show();
}
else
{
$("div[data-field-name=GlandularDetails]").hide();
}
});
});
</script>
<div class="col-md-12">
<div class="funkyradio">
<div class="funkyradio-primary col-md-4">
<input value="Yes" type="checkbox" name="GlandularFever" id="GlandularFever"/>
<label for="GlandularFever">Glandular Fever</label>

Show/Hide div using bootstrap checkbox - require inputs to be entered only if checkbox is checked

Ok, I've been having a really weird problem using a checkbox which collapses a hidden div using bootstrap.
if I have data-toggle="collapse" in the checkbox input attribute section, the Div Collapses but requires that every single one of the inputs inside it be filled out.
If data-toggle="collapse" is not there, the hidden div doesn't collapse, and if the checkbox is checked it requires the inputs to be entered and if it's left unchecked I can submit the form without the inputs being entered. (desired action, but the div doesn't hide or show when the checkbox is checked)
How do I hide/show the div when the checkbox is unchecked/checked AND only require the inputs if the box is checked?
I'm using this as the HTML:
<div class="col-md-1">
<input type="checkbox" onclick="ChangeShip()" href="#moreabout" data-toggle="collapse" aria-expanded="false" aria-controls="moreabout" class="form-control" id="chShipAdd" name="chShipAdd" value="no">
</div>
<label for="chShipAdd" class="col-md-3 control-label">Shipping Information?</label>
<div id="shipadddiv" style="visibility: hidden;">
<div class="collapse" id="moreabout" >
<div class="form-group">
<div class="col-md-12">
<br>
<input id="sStreet" name="sStreet" type="text" placeholder="Street Name (required)" class="form-control shipClass" required>
</div>
</div>
<div class="form-group">
<div class="col-md-4">
<input id="sCity" name="sCity" type="text" placeholder="City (required)" required class="form-control shipClass">
</div>
<div class="col-md-4">
<input id="sState" name="sState" type="text" placeholder="State (required)" required class="form-control shipClass">
</div>
<div class="hidden-lg hidden-md"> </div>
<div class="col-md-4">
<input id="sZipcode" name="sZipcode" type="text" placeholder="Zip (required)" required class="form-control shipClass">
</div>
</div>
</div>
</div>
and the javascript:
function ChangeShip() {
if (!(document.getElementById('chShipAdd').checked)) {
document.getElementById('shipadddiv').style.visibility="hidden";
$(".shipClass").prop("disabled",true);
}
else {
document.getElementById('shipadddiv').style.visibility="visible";
$(".shipClass").prop("disabled",false);
}
}
Any solution that WORKS will be acceptable. I've bashed my brain all day trying to do this simple action. I've tried .prop .attribute .setAttribute .removeAttribute, and much much more.
Any Advice?

You can use jquery to solve this quickly. You can wrap your inputs for change ship and give it and id. And let jquery do the rest.
var form = $('#myForm'),
checkbox = $('#changeShip'),
chShipBlock = $('#changeShipInputs');
chShipBlock.hide();
checkbox.on('click', function() {
if($(this).is(':checked')) {
chShipBlock.show();
chShipBlock.find('input').attr('required', true);
} else {
chShipBlock.hide();
chShipBlock.find('input').attr('required', false);
}
});
See this jsfiddle for your problem. This should help you.

your click event will toggle the display and the disabled, but when the form is loaded you will have hidden content that is not disabled.
simply call the function on document.ready
function ChangeShip() {
var show = $('#chShipAdd').prop('checked');
$('#shipadddiv').toggle(show);
$("#shipadddiv .shipClass").prop("disabled", !show);
}
$(ChangeShip); // call on document.ready
or simply add the disabled attribute to those elements so that the initial form state is valid
If the [required] attribute is still triggered on a [disabled] element you could juggle the attribute value
function ChangeShip() {
var show = $('#chShipAdd').prop('checked');
$('#shipadddiv').toggle(show);
$("#shipadddiv .shipClass").each(function(){
if (!('_required' in this))
this._required = this.required;
this.disabled = !show;
this.required = (show) ? this._required : false;
});
}

Try to do this :
HTML :
<div class="col-md-1">
<input type="checkbox" onclick="ChangeShip()" href="#moreabout" data-toggle="collapse" aria-expanded="false" aria-controls="moreabout" class="form-control" id="chShipAdd" name="chShipAdd" value="no">
</div>
<label for="chShipAdd" class="col-md-3 control-label">Shipping Information?</label>
<div id="shipadddiv" style="visibility: hidden;">
<div class="collapse" id="moreabout" >
<div class="form-group">
<div class="col-md-12">
<br>
<input id="sStreet" name="sStreet" type="text" placeholder="Street Name (required)" class="form-control shipClass" required>
</div>
</div>
<div class="form-group">
<div class="col-md-4">
<input id="sCity" name="sCity" type="text" placeholder="City (required)" required class="form-control shipClass">
</div>
<div class="col-md-4">
<input id="sState" name="sState" type="text" placeholder="State (required)" required class="form-control shipClass">
</div>
<div class="hidden-lg hidden-md"> </div>
<div class="col-md-4">
<input id="sZipcode" name="sZipcode" type="text" placeholder="Zip (required)" required class="form-control shipClass">
</div>
</div>
</div>
</div>
JQUERY :
$('#chShipAdd').change(function() {
if ($('#chShipAdd').prop('checked')) {
$('#shipadddiv').show();
} else {
$('#shipadddiv').hide();
}
});

Detect the name of required field and not validated when submit a form

I create a form in html5 like this example :
<form action="/my/url/insert.php" method="POST">
<div class="row">
name <input name="name" required/>
</div>
<div class="row">
type <input name="type" required/>
</div>
<div class="row">
year <input name="year" required/>
</div>
....
<div class="row">
album <input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save"/>
</div>
</form>
<script>
$('form').submit(function(){
console.log('test');
});
</script>
The problem :
I want to detect the name of the required field that are not validated when submiting and logging it.
for example : if I don't fill the input "album" when submit i detect it before the message "a field is required..."
is there a way to do this ?
thank you.

Here you go.. Loop through each input:required field and get its name with .attr.
$('form').submit(function(e) {
e.preventDefault();
$(this).find('input:required').each(function(){
console.log($(this).attr('name'));
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="/my/url/insert.php" method="POST">
<div class="row">
name
<input name="name" required/>
</div>
<div class="row">
type
<input name="type" required/>
</div>
<div class="row">
year
<input name="year" required/>
</div>
....
<div class="row">
album
<input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save" />
</div>
</form>
Updated
$('form').submit(function(e) {
e.preventDefault();
$(this).find('input:required').each(function(){
if($(this).val()==""){ //check if its empty
console.log($(this).attr('name'));
}
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form novalidate action="/my/url/insert.php" method="POST">
<div class="row">
name
<input name="name" required/>
</div>
<div class="row">
type
<input name="type" required/>
</div>
<div class="row">
year
<input name="year" required/>
</div>
....
<div class="row">
album
<input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save" />
</div>
</form>
Assuming that only required will be the property for validation, above condition will hold good and yea, by default when you say required, browser will have its validation suppressing validation written by you. If you want your validation to work, add novalidate to form as said in one of the comments above..

Select them by property required:
$(function() {
$('form').submit(function(){
$("input:required", $(this)).each(function() {
console.log($(this).attr("name"));
});
});
});
To do a simple required check on your own make a simple "not empty" condition. But for this, your form need the novalidate class, otherwise submit callback will not be triggered and nothing ever happens.
$(function() {
$('form').submit(function(){
$("input:required", $(this)).each(function() {
if( $(this).val() != "" )
console.log($(this).attr("name"));
});
});
});
Full example here: https://jsfiddle.net/vvdh66rb/

You can also do like this:
<form action="/my/url/insert.php" method="POST" onSubmit="return myFunction()">
<div class="row">
<!--I am only giving id to one to show an exmaple you can give to differnt-->
name <input name="name" id="some" required/>
</div>
<div class="row">
type <input name="type" required/>
</div>
<div class="row">
year <input name="year" required/>
</div>
....
<div class="row">
album <input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save"/>
</div>
</form>
<script>
function myFunction() {
var x = document.getElementById('some').value;
if (x == "" || x == null) {
alert('sadsd');
return false;
//You can give anything else than alert
}
}

onclick in one element show another element in javascript

i would like to click in plus ,then show the next field in every step but my code does not work in third step .is there any method to do these steps for unlimited time?tnx
<html>
<head>
<script>
function showfield(){
document.getElementById("hiddenfield").style.display="block";
}
</script>
</head>
<body>
<div class="form-group" >
<div class="rightbox"> <label for='phone'>Phone1</label></div>
<input type="tel" value="" />
<div class="plus" onClick="showfield()">+</div>
</div>
<div class="form-group" style="display:none;" id="hiddenfield">
<div class="rightbox"><label for='phone'>Phone2</label></div>
<input type="tel" value="" />
<div class="plus" onClick="showfield()">+</div></div>
</div>
<div class="form-group" style="display:none;" id="hiddenfield">
<div class="rightbox"><label for='phone'>Phone3</label></div>
<input type="tel" value="" />
<div class="plus" onClick="showfield()">+</div></div>
</div>
</body>
</html>

You can use unique id for each hidden field, then send current id to your function as parameter.
function showfield(id) {
document.getElementById(id).style.display="block";
}
Another option is jquery:
$('.plus').on('click', function() {
$(this).parent().next().show();
});
Check out jsfiddle.

As others noted, ID of an element must be unique, you can use class to group similar elements.
What you need to do is to show the first hidden field group,
function showfield() {
var el = document.querySelector(".hiddenfield");
if (el) {
el.classList.remove('hiddenfield')
}
}
.hiddenfield {
display: none;
}
<div class="form-group">
<div class="rightbox">
<label for='phone1'>Phone1</label>
</div>
<input type="tel" value="" />
<div class="plus" onClick="showfield()">+</div>
</div>
<div class="form-group hiddenfield">
<div class="rightbox">
<label for='phone2'>Phone2</label>
</div>
<input type="tel" value="" />
<div class="plus" onClick="showfield()">+</div>
</div>
<div class="form-group hiddenfield">
<div class="rightbox">
<label for='phone3'>Phone3</label>
</div>
<input type="tel" value="" />
<div class="plus" onClick="showfield()">+</div>
</div>
Supported in IE10+

Since you've tagged jquery, you could do away with all those (duplicate ids) and showField() and within doc load add this:
$('.plus').on('click', function() {
$(this).parent().next().show();
});
[Edit: Oh, here's the fiddle]
However, I'm not sure what you want to happen when the third + is clicked as there are no more divs to show.

Change id="hiddenfield" to class="hiddenfield" in all divs and change showfield as below :-
function showfield() {
document.getElementsByClassName("hiddenfield").style.display="block";
}
Note:- Supported Browsers IE9+, Chrome 4+, FF3+.

Change input to TinyMCE on click?

I'm displaying a list of input fields, which looks like the code below. What I want to do is change the input to a TinyMCE window on click() or hover(). To do this I wrote the javascript below, but that isn't working obviously since they're not <textarea's.
HTML
<div class="col-md-12">
<div class="col-md-3">
<input id="first" class="input-field" value="test1"/>
</div>
<div class="col-md-3">
<input id="second" class="input-field" value="test2"/>
</div>
<div class="col-md-3">
<input id="third" class="input-field" value="test3"/>
</div>
<div class="col-md-3">
<input id="fourth" class="input-field" value="test4"/>
</div>
<!--This continues for some time-->
<div class="col-md-3">
<input id="fiftyseventh" class="input-field" value="test57"/>
</div>
<div class="col-md-3">
<input id="fiftyeight" class="input-field" value="test58"/>
</div>
<div class="col-md-3">
<input id="fiftyninth" class="input-field" value="test59"/>
</div>
<div class="col-md-3">
<input id="sixtieth" class="input-field" value="test60"/>
</div>
</div>
javascript
$("body").on("click", "input.input-field" function() {
var id = $(this).attr("id");
tinymce.EditorManager.execCommand("mceRemoveEditor", true, id);
tinymce.EditorManager.execCommand("mceAddEditor", true, id);
});

I thing issue is in your javascript code.
Please check this line-
$("body").on("click", "input.input-field" function() {
there is no "," (comma) after adding input.input-field. i should be there.
$("body").on("click", "input.input-field", function() {
and i have checked your all code is working fine.
Here is a DEMO
