jQuery: Check if button is clicked - javascript

I have two buttons in a form and want to check which one was clicked.
Everything works fine with radioButtons:
if($("input[#name='class']:checked").val() == 'A')
On simple submit button everything crash.
Thanks!

$('#submit1, #submit2').click(function () {
if (this.id == 'submit1') {
alert('Submit 1 clicked');
}
else if (this.id == 'submit2') {
alert('Submit 2 clicked');
}
});

You can use this:
$("#id").click(function()
{
$(this).data('clicked', true);
});
Now check it via an if statement:
if($("#id").data('clicked'))
{
// code here
}
For more information you can visit the jQuery website on the .data() function.

jQuery(':button').click(function () {
if (this.id == 'button1') {
alert('Button 1 was clicked');
}
else if (this.id == 'button2') {
alert('Button 2 was clicked');
}
});
EDIT:- This will work for all buttons.

$('input[type="button"]').click(function (e) {
if (e.target) {
alert(e.target.id + ' clicked');
}
});
you should tweak this a little (eg. use a name in stead of an id to alert), but this way you have more generic function.

$('#btn1, #btn2').click(function() {
let clickedButton = $(this).attr('id');
console.log(clickedButton);
});

try something like :
var focusout = false;
$("#Button1").click(function () {
if (focusout == true) {
focusout = false;
return;
}
else {
GetInfo();
}
});
$("#Text1").focusout(function () {
focusout = true;
GetInfo();
});

if and else part not working in query

i tried the if else statement in jquery but it is not working.here is my code.
jQuery(document).ready(function () {
jQuery(".checkboxes").hide();
//toggle the componenet with class msg_body
jQuery(".Select").click(function () {
jQuery(this).next(".checkboxes").slideToggle(500);
if ($(".select").text() == "+") {
alert('hi');
$(".select").html() == "-"
}
else {
$(".select").text() == "+";
}
return false;
});
});
any help will be appreciated.
I guess it is a typo.. Put capital "S" instead of "s" as in your click event.
try below code :-
if ($(".Select").text() == "+") {
alert('hi');
$(".Select").html("-");
}
else {
$(".Select").text() == "+";
}
or simply use $(this) as below:-
if ($(this).text().trim() == "+") {
$(this).html("-");
} else {
$(this).text("+");
}
You can't assign a value to a function call. Your code should throw an error like Uncaught ReferenceError: Invalid left-hand side in assignment
jQuery(function ($) {
$(".checkboxes").hide();
//toggle the componenet with class msg_body
$(".Select").click(function () {
$(this).next(".checkboxes").slideToggle(500);
$(this).text(function (i, txt) {
return txt.trim() == '+' ? '-' : '+'
})
return false;
});
});
First of all, you are using two different classes .Select and .select. I think problem lies here. And second thing, it should be html('-') not html() == '-' because it is a logical/conditional statement and it will return a boolean. It is not an assignment statement. So your code should be:
jQuery(document).ready(function () {
jQuery(".checkboxes").hide();
//toggle the componenet with class msg_body
jQuery(".select").click(function () {
jQuery(this).next(".checkboxes").slideToggle(500);
if ($(".select").text() == "+") {
alert('hi');
$(".select").html("-");
}
else {
$(".select").text("+");
}
return false;
});
});
I suppose that correct class is select as you have used it more than Select.
Check out this fiddle: JsFiddle
You should change your code to this while assigning it is $(".Select").html("-");
jQuery(document).ready(function () {
jQuery(".checkboxes").hide();
//toggle the componenet with class msg_body
jQuery(".Select").click(function () {
jQuery(this).next(".checkboxes").slideToggle(500);
if ($(".Select").text() == "+") {
alert('hi');
$(".Select").html("-");
}
else {
$(".Select").text("+");
}
return false;
});
});

code not working without an alert() in javascript

my problem is the following code is not working without an alert().I am using a two level select/deselct all box. but the code is working for one level only. It is not being able to deselect the 'select all' checkbox on unchecking a single checkbox or vice-versa without the alert..
alert('17');
$('input.DataCheckAll').click(function() {
if ($('input.DataCheckAll').length == $('input.DataCheckAll:checked').length) {
$('input.CheckAll').prop('checked', true);
} else {
$('input.CheckAll').prop('checked', false);
}
});
if ($('input.CheckAll').length > 0) {
$('input.CheckAll').attr('checked', false);
$('input.CheckAll').click(function() {
if (this.checked) {
$('input.DataCheckAll').each(function() {
this.checked = true;
});
} else {
$('input.DataCheckAll').each(function() {
this.checked = false;
});
}
});
}
It's highly likely that you just need to wrap it in $(function() { /* code */ });. At present, your code is being stopped by the alert, which lets the document load in the background so by the time you close the alert, the page is ready for everything you're trying to do.
By just telling it to wait until the page has finished loading, you shouldn't need the alert any more.
$(function() {
// code
});
is exactly the same as
$(document).ready(function() {
// code
});
The code is probably running before the dom is ready, Try this:
$(function(){ //by passing jQuery a function instead of a selector
// it will call the function when the dom is ready
$('input.DataCheckAll').click(function() {
if ($('input.DataCheckAll').length == $('input.DataCheckAll:checked').length) {
$('input.CheckAll').prop('checked', true);
} else {
$('input.CheckAll').prop('checked', false);
}
});
if ($('input.CheckAll').length > 0) {
$('input.CheckAll').attr('checked', false);
$('input.CheckAll').click(function() {
if (this.checked) {
$('input.DataCheckAll').each(function() {
this.checked = true;
});
} else {
$('input.DataCheckAll').each(function() {
this.checked = false;
});
}
});
}
});
You should execute your jquery script after DOM is ready, so wrap it inside $(function(){});
NOTE - Also, you need not to iterate $('input.DataCheckAll') using .each(), to check / uncheck. You can simply use $('input.DataCheckAll').prop('checked',true);
$(function(){
$('input.DataCheckAll').click(function() {
if ($('input.DataCheckAll').length == $('input.DataCheckAll:checked').length) {
$('input.CheckAll').prop('checked', true);
} else {
$('input.CheckAll').prop('checked', false);
}
});
if ($('input.CheckAll').length > 0) {
$('input.CheckAll').attr('checked', false);
$('input.CheckAll').click(function() {
/*if (this.checked) {
$('input.DataCheckAll').each(function() {
this.checked = true;
});
} else {
$('input.DataCheckAll').each(function() {
this.checked = false;
});
}*/
// to select / deselect all data check boxes
$('input.DataCheckAll').prop('checked',this.checked);
});
}
});

Hide and show particular form items on checked and unchecked selectbox?

I am using the below given code to hide and show particular form items, but this doesn't work kindly let me know what I am missing in my code?
HTML:
<input id="id_code_col" type="checkbox" name="code_col"></input>
SCRIPT:
$(document).ready(function(){
var selectBox = jQuery('#id_code_col');
selectBox.change(function () {
if ($(this).val() == '1') {
$('#id_FullColumn').show();
$('#id_FirstColumn').hide();
$('#id_SecondColumn').hide();
}
else {
$('#id_FullColumn').hide();
$('#id_FirstColumn').show();
$('#id_SecondColumn').show();
}
});
});
N.B: I can not add or remove anything from html. What ever I have to do is to do it with script. Kindly help!
do like this:
if(this.checked)
{
// checked
}
else
{
// unchecked
}
for your case:
$(document).ready(function(){
var selectBox = jQuery('#id_code_col');
selectBox.change(function () {
if (this.checked) {
$('#id_FullColumn').show();
$('#id_FirstColumn').hide();
$('#id_SecondColumn').hide();
}
else {
$('#id_FullColumn').hide();
$('#id_FirstColumn').show();
$('#id_SecondColumn').show();
}
});
});
selectBox.change(function () {
if ($(this).is(':checked')) {
$('#id_FullColumn').show();
$('#id_FirstColumn').hide();
$('#id_SecondColumn').hide();
}
else {
$('#id_FullColumn').hide();
$('#id_FirstColumn').show();
$('#id_SecondColumn').show();
}
});
You can use .is() along with :checked selector to check whether your checkbox is checked or not, so try to use:
if ($(this).is(':checked')) {
or pure javascript using:
if(this.checked)
instead of:
if ($(this).val() == '1') {
Change this
if ($(this).val() == '1') {
to this
if (this.checked) {
Because you don't have to check for the value to 1, as your checkbox doesn't have any value set to 1.
So you have to check for the state of that checkbox with checked method.
$(document).ready(function () {
var selectBox = jQuery('#id_code_col');
selectBox.change(function () {
if (this.checked) {
alert("checked");
}
else {
alert("unchecked");
}
});
});
$(function(){
$('#id_code_col').change(function(){
if($(this.checked)){
alert('checked');
}else{
alert('unchecked');
}
});
});

click multiple elements to hide or show something - jquery

here is my script. Now i can click one of these IDs and class "inputs" are visible. What i want is that I have to click on all elements.
$('#zwei,#sechs,#neun').bind('click', function() {
if( $(this).is(':checked')) {
$('.inputs').show();
} else {
$('.inputs').hide();
}
});
JSFiddle:
http://jsfiddle.net/CLYC6/20/
can you help me please? whats wrong?
FK
Use this:
$('#zwei,#sechs,#neun').bind('click', function() {
$('.inputs').show();
$('#zwei,#sechs,#neun').each(function (e) {
if (!$(this).is(':checked')) {
$('.inputs').hide();
return;
}
});
});
Here is a LIVE DEMO.
Because #Rastko is not happy with the current solution here is one more:
$('#zwei,#sechs,#neun').bind('click', function() {
var showInput = true;
$('#zwei,#sechs,#neun').each(function (e) {
if (!$(this).is(':checked')) {
showInput = false;
return;
}
});
if (showInput) {
$('.inputs').show();
} else {
$('.inputs').hide();
}
});
One more LIVE DEMO.
If statement should check whether all three are checked, and if input is not visible.
so:
if($('#zvei').is(':checked') && $('#neun').is(':checked') && $('#sechs').is(':checked') {
$('.inputs').show();
}

JQuery Check if input is empty not checking onload?

I am using this code to check if an inputbox is empty or not and it works fine but it only checks check a key is press not when the page loads.
It's does what it should but I also want it to check the status when the page loads.
Here is the current code:
$('#myID').on('keyup keydown keypress change paste', function() {
if ($(this).val() == '') {
$('#status').removeClass('required_ok').addClass('ok');
} else {
$('#status').addClass('required_ok').removeClass('not_ok');
}
});
Try the following:
$(function() {
var element = $('#myID');
var toggleClasses = function() {
if (element.val() == '') {
$('#status').removeClass('required_ok').addClass('ok');
} else {
$('#status').addClass('required_ok').removeClass('not_ok');
}
};
element.on('keyup keydown keypress change paste', function() {
toggleClasses(); // Still toggles the classes on any of the above events
});
toggleClasses(); // and also on document ready
});
The simplest way to do is trigger any of the keyup,keydown etc event on page load. It will then automatically call your specific handler
$(document).ready(function(){
$("#myID").trigger('keyup');
});
try checking the value on a doc ready:
$(function() {
if ($('#myID').val() == '') {
$('#status').removeClass('required_ok').addClass('ok');
} else {
$('#status').addClass('required_ok').removeClass('not_ok');
}
});
EDIT: just as an update to this answer, a nicer approach might be to use toggle class, set up in doc ready then trigger the event to run on page load.
function check() {
var $status = $('#status');
if ($(this).val()) {
$status.toggleClass('required_ok').toggleClass('ok');
} else {
$status.toggleClass('required_ok').toggleClass('not_ok');
}
}
$(function () {
$('#myID').on('keyup keydown keypress change paste', check);
$('#myID').trigger('change');
});
Well then why dont just check the field after the page is loaded?
$(document).ready(function(){
if ($('#myID').val() == '') {
$('#status').removeClass('required_ok').addClass('ok');
} else {
$('#status').addClass('required_ok').removeClass('not_ok');
}
});
$(document).ready(function(){
var checkVal = $("myID").val();
if(checkVal==''){
$('#status').removeClass('required_ok').addClass('ok');
}
else{
$('#status').addClass('required_ok').removeClass('not_ok');
}
});
