What i'm trying to do here is if the selection is equal to value 10 the click function to be available only if selection is equal to 10. But when i change to other ex. category with different value the radio click function is still available. ?
I have 6 radio boxes with value 1,2,3,4,5,6 so what i want to do if value == 4 to slidedown another div while i'm in category with value 10.(selection).
How can i fix this problem ? Here is my sample code.
$('#category').on('change', function () {
var selection = $(this).val();
$('#slidedown'+selection).slideDown(200);
if(selection == '10'){
$("input:radio[name='checkbox']").click(function() {
var radio = $(this).val();
if(radio == '4' && selection == '10') {
$('#slidedown'+selection).slideUp();
} else {
$('#slidedown'+selection).slideDown();
}
});
});
Thanks, any help will be appreciated.
EDIT : I want to slideUp the currect div which is slided down by the category value if radio box with value 4 is checked.
You should have another selection var inside the click callback:
$('#category').on('change', function () {
var selection = $(this).val();
$('#slidedown'+selection).slideDown(200);
});
$("input:radio[name='checkbox']").click(function() {
var selection = $('#category').val(); //This does the trick
var radio = $(this).val();
if(radio == '4' && selection == '10') {
$('#slidedown_another').slideUp();
} else {
$('#slidedown_another').slideDown();
}
});
Also, callbacks must be separated for not binding a new listener each time
Hope this helps. Cheers
Use the disabled property to enable and disable the radio buttons.
$('#category').change(function() {
var selection = $(this).val();
$('#slidedown'+selection).slideDown(200);
$('input:radio[name=checkbox]').prop('disabled', selection != '10');
});
$("input:radio[name='checkbox']").click(function() {
var radio = $(this).val();
if(radio == '4') {
$('#slidedown_another').slideUp();
} else {
$('#slidedown_another').slideDown();
}
});
Your code is adding a handler when the select has the correct value, but it never removes the handler when the select changes to a different value. Also, every time they select 10 it was adding another handler, so the handler would then run multiple times.

have 5 radio button(yes or no) and I want to do is whenever I select 'Yes' either those buttons my textarea will color red, and I've already done that. but the problem is whenever I've select only one 'Yes' and change it to No the color of the textarea still remains on red
$('.com_lease_checkbox').on("change", function() {
console.log($(this).val());
$(".com_lease_checkbox:checked").each(function(){
// Check if the value is Yes
if ($(this).is(':checked') && $(this).val() == 'Yes') {
// Set the color of text-area
$('.com_lease_desc_a').css("border-color","red");
}
});
});
Simple way to do this is to Count How many selected 'No's .. if it's Zero it's OK else Red
$('.com_lease_checkbox').on("change", function() {
//var selectedYesCheckBoxesCount = $(".com_lease_checkbox[value='Yes']:selected").length;
var selectedNoCheckBoxesCount = $(".com_lease_checkbox[value='No']:selected").length;
if(selectedNoCheckBoxesCount > 0) {
$('.com_lease_desc_a').css("border-color","red");
}
else {
$('.com_lease_desc_a').css("border-color","green");
}
});
I have a form with three select options:
Fit
Colour
Size
By default, the 'Fit' dropdown and 'Colour' dropdown are active with a default value selected (e.g. Regular Fit and Blue Colour).
There are three different 'Size' dropdowns, but only one is visible at any time depending on what is selected from the 'Fit' dropdown.
The Button is disabled if an option value="none".
Problem
The Button only becomes active if all three 'Size' dropdowns are altered so that their value is not "none" (this is done by selecting an initial size for Regular, and then selecting Petite and Long from the 'Fit' dropdown). Ideally, I only want the button to take into account the 'Size' dropdown that is active.

If we want to disable the button by combination of the drop down selected values. We can have a global variable to track the current selected values from three drop downs. Only we can have array of disbale combos. So whenever user select a value we cross check with disable combos and if it matches we can disable the button. Validate the combo can be done as below. Updated the jsfiddle link. JS FIDDLE UPDATED
function checkDisableCombo() {
return $.grep(disableComboVals, function(vals){
cnt = 0;
$.each(vals, function(key,val) {
console.log('comparing key val '+key+val);
if (val === '' || val === currentSelectedVals[key]) {
console.log('>>matched values');
cnt = cnt + 1;
}
});
if (cnt===3) {
return true;
}
return false;
});
Is it possible to identify if the value of radio button has not changed?
Currently I am trying to change the confirmation message of submit button on button changed, and do not want any message if the value has not changed. I have something like this now:
$('input[type="radio"]').change(function() {
var selected = $('input:checked[type="radio"]').val();
if(selected == 'true') {
$("#submit_button").data("confirm", "foo");
} else if(selected == 'false') {
$('#fee').hide();
$("#submit_button").data("confirm", "bar");
}
This will change confirm message to foo if button selected is true, and bar if button selected is false. However, what if I want to return nothing (no message), if radio button by default is true, and selected is true?
You can start a variable outside the event:
var radioChanged = 0;
And, in your event increase it:
$(':radio').change(function() {
radioChanged += 1;
// your code ...
});
Then, later on:
if (radioChanged > 0) {
alert('Change function occurred ' + radioChanged + ' times.');
} else {
alert('Radio button not changed.');
}
As i understand your expected behaviour, check if any radio has no more its default checked value:
$('form').on('submit', function() {
var anyRadioChanged = !!$(this).find('input[type="radio"]').filter(function() {
return $(this).is(':checked') != this.defaultChecked;
}).length; // '!!' to get boolean but it doesn't really matter here
if(anyRadioChanged) {
// show message(???)
}
})
you can hide message element just adding display: none to it or use jquery hide method
$('#someElementId').hide();
or
$('#someElementId').css("display","none")
I need to rewrite this section of a jQuery script so that it is triggered by selection of a radio button and not a dropdown.
var check_engraving = $('#attrib-2');
if (check_engraving.val() == 4) {
enable_engraving = true;
$('#individual_engraving_wrapper').show();
The new radio button that needs to trigger it is:
<span class="EngraveAttribute4"><input type="radio" name="id[2]" value="540" id="attrib-2-540" /><label class="attribsRadioButton zero" for="attrib-2-540">I would like different engraving on each of these items</label><br /></span>
It's obviously no good changing it to
var check_engraving = $('#attrib-2-540');
if (check_engraving.val() == 540) {
as the value is always 540 regardless of whether or not it is selected.
I tried to use
$('input:radio[name="id[2]"]').change(function () {
if ($(this).val() == '540') {
enable_engraving = true;
$('#individual_engraving_wrapper').show();
}
});
which I thought was working ok, but if I update the quantity I have to deselect then reselect the radio button for engraving to be true. The old dropdown system stayed as true when the quantity was updated.
I'm sure this can be done, but I'm stumped on it. Any suggestions appreciated.
try this
$('input[type=radio][name="id[2]"]').change(function () {
if ($(this).val() == '540') {
enable_engraving = true;
$('#individual_engraving_wrapper').show();
}
});
With the help of answers I found here, I try to disable submit button and send an alert message when clicked on it until there's not at least 2 checkboxes checked.
What I am doing wrong ?
var selected = $('#frmCompare :checkbox:checked').length;
function verifCompare() {
if (selected >= 2) {
//good
$('#frmCompare').submit();
} else {
//bad
alert('Veuillez selectionner au moins 2 produits à comparer...');
return false
}
}
$(document).ready(function () {
$('#btnCompare').attr('disabled', 'disabled');
$('#frmCompare :checkbox').change(function () {
//alert(selected);
if (selected >= 2) {
$('#btnCompare').attr('enabled');
}
});
});
At this point, only alert message works.
Fiddle
EDIT : added fiddle
There is no enabled attribute in HTML.
$('#btnCompare').prop('disabled', selected < 2);
You also need to recalculate the value of selected at every change, you can't just go with what it was set to at page load.
You initialize the count of checked checkboxes just once, when your script is first parsed. The count will not be recomputed later. This line:
var selected = $('#frmCompare :checkbox:checked').length;
should be inside the verification function, not outside.
You should change your code as
$('#frmCompare :checkbox').change(function(){
//update selected variable
selected = $('#frmCompare :checkbox:checked').length
if (selected >= 2) {
$('#btnCompare').attr('enabled');
}
});
