jQuery group of checkbox issue

I have two group of checkbox newBuilding & oldBuilding.
Idea over here is I can select checkbox only one of the group.
In each group there is checkbox name other area, so I when click on it, it will show and hide textbox next to it.
Now to achieve first point, lets for example that already we have oldBuilding checkboxes are checked and I if I click one of the newBuilding checkbox then it will remove the check from oldBuilding group but newBuilding checkbox will not get checked but just get focus, I have to click again to check.
What I found out that above issue happen when I call trigger event. How can I overcome the issue
Code for other area
$("#chkOldBuildingOtherAreas").change(function () {
if ($("#chkOldBuildingOtherAreas").is(":checked"))
$("#txOldOtherAreas").show();
else
$("#txOldOtherAreas").hide();
});
$("#chkNewBuildingOtherAreas").change(function () {
if ($("#chkNewBuildingOtherAreas").is(":checked"))
$("#txNewOtherAreas").show();
else
$("#txNewOtherAreas").hide();
});
Code for removing check mark from other groups
$("input[name='oldBuilding']").change(function () {
if ($("input[name='newBuilding']:checked").length > 0) {
$("input[name='newBuilding']").removeAttr('checked');
$("#chkNewBuildingOtherAreas").trigger("change");
}
});
$("input[name='newBuilding']").change(function () {
if ($("input[name='oldBuilding']:checked").length > 0) {
$("input[name='oldBuilding']").removeAttr('checked');
$("#chkOldBuildingOtherAreas").trigger("change");
}
});
My jsfiddle
https://jsfiddle.net/milindsaraswala/wchrwjnx/

https://jsfiddle.net/1ny36nwL/4/
var groups = ['.oldGroup', '.newGroup'];
$(groups.join(',')).find('input[type=text]').hide();
function resetGroup(selector) {
//clear and hide texts
$('input[type=text]', selector).val('').hide();
//uncheck boxes
$('input[type=checkbox]', selector).removeAttr('checked');
}
$("input[name='oldBuilding']").change(function(e) {
if (this.id == 'chkOldBuildingOtherAreas') {
$("#txOldOtherAreas").toggle();
}
resetGroup('.newGroup');
});
$("input[name='newBuilding']").change(function(e) {
if (this.id == 'chkNewBuildingOtherAreas') {
$("#txNewOtherAreas").toggle();
}
resetGroup('.oldGroup');
});
as you can see I added groups var which can contain multiple groups (not only two), but code need to be changed a little more for that to work
you need to detect id/class of current group by something like $(this).closest('.form-group').id and reset every group except current group. in that way you can leave only one change function which will be universal
oh and you also need to add some class for checkbox that contain text input, and if that checkbox is clicked, trigger toggle for input. so it won't be if (this.id == 'chkNewBuildingOtherAreas') { but something like if ($(this).hasClass('has-input'))

Try replacing this in your code. It should work.
$("#txOldOtherAreas").hide();
$("#txNewOtherAreas").hide();
$("input[name='oldBuilding']").change(function (e) {
$("input[name='newBuilding']").removeAttr('checked');
e.target.checked = true;
if (e.target.id == "chkOldBuildingOtherAreas") {
$("#txOldOtherAreas").show();
$("#txNewOtherAreas").hide();
} else {
$("#txNewOtherAreas").hide();
}
});
$("input[name='newBuilding']").change(function (e) {
$("input[name='oldBuilding']").removeAttr('checked');
e.target.checked = true;
if (e.target.id == "chkNewBuildingOtherAreas") {
$("#txNewOtherAreas").show();
$("#txOldOtherAreas").hide();
} else {
$("#txOldOtherAreas").hide();
}
});

You can try following code to fix the problem (Tested in fiddle):
$('#txNewOtherAreas, #txOldOtherAreas').hide();
$('input[name="oldBuilding"]').on('click', function(){
if($('input[name="newBuilding"]').is(':checked')){
$('input[name="newBuilding"]').removeAttr('checked');
$('#txNewOtherAreas').hide();
}
});
$('input[name="newBuilding"]').on('click', function(){
if($('input[name="oldBuilding"]').is(':checked')){
$('input[name="oldBuilding"]').removeAttr('checked');
$('#txOldOtherAreas').hide();
}
});
$('#chkNewBuildingOtherAreas').on('click', function() {
if($(this).is(':checked')){
$('#txNewOtherAreas').show();
} else {
$('#txNewOtherAreas').hide();
}
});
$('#chkOldBuildingOtherAreas').on('click', function() {
if($(this).is(':checked')){
$('#txOldOtherAreas').show();
} else {
$('#txOldOtherAreas').hide();
}
});

JavaScript variable unset after the second click event time

I have this code which asks a question; askQuestion()
which runs as the page loads and runs again when a button with id wb_option_button is clicked.
But I noted that at the first click, its runs well, but the second click never never run. I want to know what is wrong with it (in case), and how to do it work.
var q_selected;
var q_number = 1;
var questionDiv = $('.wb_questions');
var optionDiv = $('div#wb_options');
function askQuestion()
{
questionDiv.html(questions[q_number]['question']);
optionDiv.html('<button class="wb_option_button" id="wb_option_button" title="click to answer">'+questions[q_number]['options'][0]+'</button>'+
'<button class="wb_option_button" id="wb_option_button" title="click to answer">'+questions[q_number]['options'][1]+'</button>'+
'<button class="wb_option_button" id="wb_option_button" title="click to answer">'+questions[q_number]['options'][2]+'</button>'+
'<button class="wb_option_button" id="wb_option_button" title="click to answer">'+questions[q_number]['options'][3]+'</button>'
);
}
function checkAnswer(q_answer)
{
if(q_selected === q_answer)
{
return true;
}
}
function isCheckpoint()
{
if(checkpoints[q_number]!=null)
{
return true;
}
else
{
return false;
}
}
askQuestion();
$('button.wb_option_button').click(function(){
q_selected = $(this).text();
if(checkAnswer(questions[q_number]['answer'])===true)
{
if(isCheckpoint()===true)
{
showRank(q_number);
}
else
{
q_number+=1;
//alert(q_number);
askQuestion();
// showStage();
return q_number;
}
}
else
{
alert("You failed");
}
});
var questions is an object, var checkpoints ia also an object.

All of your buttons have the same ID. When you get an Element by id, it will only return the first element it finds with this id. If you want to get multiple elements you have to get them with another selector, ie. by className or any other means then by ID.
Edit : You are in fact selecting the buttons by className. The problem is that when you call askQuestion() again, the click listener is not added to the new buttons, so you might want to move the click event assignment inside askQuestion
Hope this helps.

After a little more digging, I arrived at this solution which works perfectly.
Thank you all for your help!!!
$('.wb_options').on('click','.wb_option_button',function(){
q_selected = $(this).text();
if(checkAnswer(questions[q_number]['answer'])===true)
{
if(isCheckpoint()===true)
{
showRank(q_number);
}
else
{
q_number+=1;
askQuestion();
alert(q_number);
// showStage();
//return q_number;
}
}
else
{
alert("You failed");
}
});

JavaScript Echo Var Within Double Quote

Okay,
Another novice type question.
I have this array within the head section on my website and want to use it inline JavaScript:
var MyVariable = {"chkboxid":"chkbox"}
chkboxid is a id of a checkbox input.
Now, while validating the checkbox input on form submit, neither this works
$("form#myform").submit(function () {
if ($(MyVariable.chkboxid).is(":checked")) {
} else {
alert(CommentsPlus.nochkboxmsg);
return false;
}
Nor This (check the double quote at the variable)
$("form#myform").submit(function () {
if ($("MyVariable.chkboxid").is(":checked")) {
} else {
alert(CommentsPlus.nochkboxmsg);
return false;
}
However, if I hardcode the checkbox input id, it works. I mean "input#chkbox" in place of MyVariable.chkboxid.
$("form#myform").submit(function () {
if ($("input#chkbox").is(":checked")) {
} else {
alert(CommentsPlus.nochkboxmsg);
return false;
}
How can I use that variable instead of hard coding the input id?

You are missing the "#" before the ID:
$("form#myform").submit(function () {
var element = $("#" + MyVariable.chkboxid)
if (element.is(":checked")) {
} else {
alert(CommentsPlus.nochkboxmsg);
return false;
}
}
Note however that chkboxid is the key, the actual ID of the checkbox should be the value:
var MyVariable = {"chkboxid": "real_id_here"}

please check below code.hope it will work
$("form#myform").submit(function () {
if ($("#chkboxid").is("checked")) {alert("checked");
} else {
alert("not checked");
}
});
thanks,Ripa Saha

Add class if one select's value is #

$(document).ready(function () {
$("#bcscan").submit(function (e) {
e.preventDefault();
if($("select").val() === '#') {
$(this).addClass("warning");
}
else {
ajaxPost();
}
});
});
I'm using following function, how can I modify it to add class warning, if one of select element's value = "#"?
Currently it's adding warning class to all selects

I think this may be what you want:
$('select').filter(function() {
return ($(this).val() === '#');
}).addClass('warning');
That selects all select elements, filters it down to those elements whose current value is equal to #, then adds the warning class to that subset.
I'll leave my original answer here, though given the changes to the question it's likely no longer relevant. This is my last stab at guessing what it is you want - if this is useful to you, great; if not, oh well.
$(document).ready(function () {
$("#bcscan").submit(function (e) {
e.preventDefault();
var doAjaxPost = true;
$('select').each(function() {
if($(this).val() === '#') {
doAjaxPost = false;
$(this).addClass('warning');
}
});
if(doAjaxPost) {
ajaxPost();
}
});
});
That checks all select elements when the form is submitted - if any of them have a value of # it adds the warning class to that select element. If none of them have a value of # it goes ahead and calls the ajaxPost() function.

$('select').change(function (event) {
if ($(this).val() === '#') $(this).addClass('warning');
});
this is populated with the element that fired the event. In this case the select.

Edit to match the question:
$(document).ready(function () {
$("#bcscan").submit(function (e) {
e.preventDefault();
var invalidCount = $('select').filter(function() {
return ($(this).val() === '#');
}).addClass('warning').length;
if (invalidCount == 0) {
alert('valid');
}
});
});
Demo: http://jsfiddle.net/TimWolla/QxBH9/

if($("select:selected").val() == '#') {
$("select").addClass("warning");
}

Javascript: Remove checked status from disabled input (already checked)

Im trying to make this function to check an element and if its checked, or not, add or remove respective className. Also, if the element is disabled but is checked, it should un-check it and remove the className('yes')
function init() {
$(document.body).select('input').each(function(element) {
if (!element.checked) {
element.up().removeClassName('yes');
} else {
element.up().addClassName('yes');
}
if (element.checked && element.disabled) {
element.checked = false;
element.up().removeClassName('yes')
}
});
}
Right now, the last part, is not working, no effect

Did you try element.checked = !element.checked in the last part instead of element.checked = false?
