This function executes when a button is tapped. All the code works except for the first 'if' statement when I am trying to check if both 'dland' and 'advent' are checked off. See the bold code below. That if statement should execute function 'randomItinerary1' if both the 'dland' and 'advent' checkboxes are marked. The problem must lie with checking the booleans of two checkboxes in one if statement and I need a workaround. Thank you all in advance for your time and consideration.
$("#q1").on("tap", function(){
//var cv2 = $('#advent:checked').val();
navigation(page2, page4);
**if ((document.getElementById('dland').checked) && (document.getElementById('advent').checked))** {
randomItinerary1();
}
else if (document.getElementById('dland').checked) {
randomItinerary2();
}
else if (document.getElementById('advent').checked) {
randomItinerary3();
}
else {
alert("You didn't select and parks");
}
});
});
Check below code, it works for all condition
https://jsfiddle.net/nvdhuLum/
$("#q1").on("click", function(){
if ((document.getElementById('dland').checked) && (document.getElementById('advent').checked)) {
alert("both checked")
}
if (document.getElementById('dland').checked) {
alert("dland checked")
}
if (document.getElementById('advent').checked) {
alert("advent checked")
}
else {
alert("You didn't select and parks");
}
});

I am using if else condition in jQuery to handle check boxes.
My condition is that at least one check box is selected and after that alert if condition is running and not the other one. Here is my code
$(document).ready(function() {
$('#outer_menu').click(function() {
var $fields = $(this).find('input[name="mychoice"]:checked');
if (!$fields.length) {
alert('You must check at least one box!');
if(".a:checked "){
$(".language").find(".translate-language").toggleClass("translate-language translate-language_show");
} else if (".a_orignal:checked") {
$(".language").find(".orignal-language_hide").toggleClass("orignal-language_hide orignal-language");
} else {
alert('chose one');
}
return false;
}
});
});
our else if condition is not working when if condition false
I think what you are trying to do is to check whether the element with class a or a_original is checked, for that you need
if ($(".a").is(":checked ") {
$(".language").find(".translate-language").toggleClass("translate-language translate-language_show");
} else if (".a_orignal").is(":checked") {
$(".language").find(".orignal-language_hide").toggleClass("orignal-language_hide orignal-language");
} else {
alert('chose one');
}
use .is() to check whether the element satisfies the given selector
you need to fetch the jQuery object for the target element
Look at this line of code:
if(".a:checked ")
I believe it should be:
if ($(".a:checked "))
That might not be the end of your issues though, unless a is a class rather than you intending to select links.
Same problem here:
else if (".a_orignal:checked")
Change to:
if($(".a").is(":checked")){
and:
else if ($(".a_orignal").is(":checked")){
The .prop() method gets the property value for the first element in the matched set.
Write:
if(".a").prop("checked"){
$(".language").find(".translate-language").toggleClass("translate-language translate-language_show");
}
else if (".a_orignal").prop("checked"){
$(".language").find(".orignal-language_hide").toggleClass("orignal-language_hide orignal-language");
}
<script>
function no_email_confirm() {
if (document.getElementsByName("no_email")[0].checked == false) {
return true;
} else {
var box= confirm("Sure?");
if (box==true)
return true;
else
document.getElementsByName("no_email")[0].checked == false;
}
}
</script>
And here is my HTML for the checkbox:
<input type="checkbox" id="no_email" name="no_email" onchange="no_email_confirm()"></input>
For some reason, this gives me the confirm pop up the first time I check the box, but not for any click after that. Also, even if I click "Cancel" it still checks the check box. I've searched on here and for some reason, no matter what I try, I can't get it to work properly.
It should confirm if they really want to check the box, if they select "Yes" then it checks it, if not, then it doesn't check it. I can get it to work without the name no_email, but I can't change that..
Anyone have any ideas?
Looks like you've got several errors in there, most notably using == when you probably meant =. Instead, add an event listener and make sure the assignment works:
var box = document.querySelector('#no_email');
box.addEventListener('change', function no_email_confirm() {
if (this.checked == false) {
return true;
} else {
var confirmation= confirm("This means that the VENDOR will NOT RECEIVE ANY communication!!!!");
if (confirmation)
return true;
else
box.checked = false;
}
});

I'm trying to add some validation to a form. I have a jQuery function that is doing exactly what I want:
jQuery('#post').submit(function() {
if (jQuery("#set-post-thumbnail").find('img').size() > 0) {
jQuery('#ajax-loading').hide();
jQuery('#publish').removeClass('button-primary-disabled');
return true;
}else{
alert("Please set a Featured Image!");
jQuery('#ajax-loading').hide();
jQuery('#publish').addClass('button-primary-disabled');
return false;
}
return false;
});
However, I want to change it so that this function only runs if a radio button elsewhere on the page is selected. So I tried this:
if (jQuery('#top').checked) {
jQuery('#post').submit(function() {
if (jQuery("#set-post-thumbnail").find('img').size() > 0) {
jQuery('#ajax-loading').hide();
jQuery('#publish').removeClass('button-primary-disabled');
return true;
}else{
alert("Please set a Featured Image!");
jQuery('#ajax-loading').hide();
jQuery('#publish').addClass('button-primary-disabled');
return false;
}
return false;
});
}
That doesn't work - the function doesn't get called even if #top is checked. Can anyone explain why? I'm used to PHP, and JavaScript often throws curveballs at me.
What does firebug or Chrome console tell you? You could try something like this:
$('#top').is(':checked')
as in (thanks RET):
jQuery('#post').submit(function() {
if ($('#top').is(':checked')) {
if (jQuery("#set-post-thumbnail").find('img').size() > 0) {
jQuery('#ajax-loading').hide();
jQuery('#publish').removeClass('button-primary-disabled');
return true;
}else{
alert("Please set a Featured Image!");
jQuery('#ajax-loading').hide();
jQuery('#publish').addClass('button-primary-disabled');
return false;
}
}
return false;
});
try
$('#top').is(':checked')
but the function submit only binds the function and calls it every time submit is clicked.
so you must put the checked check in the submit function
jQuery('#post').submit(function() {
if(!$('top').is(':checked')){ return };
if (jQuery("#set-post-thumbnail").find('img').size() > 0) {
jQuery('#ajax-loading').hide();
jQuery('#publish').removeClass('button-primary-disabled');
return true;
}
alert("Please set a Featured Image!");
jQuery('#ajax-loading').hide();
jQuery('#publish').addClass('button-primary-disabled');
return false;
});
Yeah, that logic won't quite do what you're hoping for. Try something like:
jQuery('#post').submit(function() {
if ($('#top').is(':checked')) {
// all your existing code
I could be wrong, but I don't think the answer given by #greener is going to work, because that will only declare the submit function if #top is checked at page create time.
I want to check a textarea whether it is empty or not. For this I write the following code:
function validateForm(theForm) {
var problem_desc = document.getElementById("problem_desc");
if (problem_desc.value == '') {
alert("Please Write Problem Description");
return false;
} else {
return true;
}
}
For the first time it is working fine. But If I remove the text from the textarea the above function is returning true value i.e., it is assuming the previous text I've entered into the textbox. Can anybody kindly tell me where is the problem?
I am getting it correctly. This is what I did.
Click on validate, it said Please Write Problem Description.
Write something and click. Nothing happened.
Remove the text. Click on validate, it said Please Write Problem Description.
Note: Use a trim function to eliminate empty spaces.
Code:
function validateForm(theForm) {
var problem_desc = document.getElementById("problem_desc");
if ($.trim(problem_desc.value) == '') {
alert("Please Write Problem Description");
return false;
} else {
return true;
}
}
Demo: http://jsfiddle.net/TZGPM/1/ (Checks for Whitespaces too!)
Do check for white space in the value like this
if (problem_desc.value.match (/\S/)) { ... }
or other way check for length
problem_desc.value.length == 0;
Remove spaces and calculate length of the value attribute.
function validateForm(theForm) {
var problem_desc = document.getElementById("problem_desc");
if (problem_desc.value.replace(/ /g,'').length) {
return true;
} else {
alert("Please Write Problem Description");
return false;
}
}
<textarea id="problem_desc"></textarea>
<button onclick="validateForm()">Validate</button>
If (acctRB.Checked == true)
{
Execute Business Code
}
Well, you don't need the == true:
if (acctRB.checked)
{
// It's checked
}
else
{
// It's not checked
}
So what you have is pretty much correct. Just remove the == true as it's not required.
Bear in mind that IE is case insensitive while other browsers aren't. Your sample code will work for IE....
Rather do
if (acctRB.checked) {
//Checked
} else {
//Unchecked
}
It works for both IE and other major browsers....Or, if if checkbox id is "acctRB" do,
if (document.getElementById("acctRB").checked) {
//Checked
} else {
//Unchecked
}
