How to detect if the click event occurred using jQuery? - javascript

I have 2 buttons. I want to detect if the previous button clicked then on 2nd button click it should display some data otherwise if user is directly clicking on the second button, it should display an alert(please click the previous button first). I have tried to do so but not able to detect whether the 1st button is clicked or not :-(
HTML
<input type="button" id="btn1" value="button1"></input>
<input type="button" id="btn2" value="button2"></input>
JavaScript
$('#btn1').click(function(){
alert('Button 1 Clicked');
});
$('#btn2').click(function(event) {
var inputButton = document.getElementsByTagName('input');
var $target = $(event.target);
if( $target.is(inputButton[1]) ) {
alert("Please click the 1st Button first");
} else{
alert('Button 2 Clicked');
}
});

EDIT: I chose not to use a variable, because there's not really much reason to use one. Avoiding unnecessary scope pollution, and whatnot.
HTML
<button id="btn1">First Button</button>
<button id="btn2">Second Button</button
JavaScript
$(document).ready(function() {
$('#btn1').on('click', function() {
alert('Button 1 clicked');
$('#btn2').data('btn1-clicked', true);
});
$('#btn2').on('click', function() {
var el = $(this);
if (el.data('btn1-clicked')) {
alert('Button 2 clicked');
} else {
alert('Please click the 1st button first');
}
})
});

You could use this, creating a variable to store a true/false related to the first button:
var btn_clicked = false;
$('#btn1').click(function () {
btn_clicked = true;
alert('Button 1 Clicked');
});
$('#btn2').click(function (event) {
var inputButton = document.getElementsByTagName('input');
var $target = $(event.target);
if (!btn_clicked) {
alert("Please click the 1st Button first");
} else {
alert('Button 2 Clicked');
}
});
Demo here

Try this one define a global variable to track the click of first button
var buttonclicked=false;
$('#btn1').click(function(){
buttonclicked=true;
alert('Button 1 Clicked');
});
$('#btn2').click(function(event) {
if(!buttonclicked){
alert("please click button1 first")
}else{
var inputButton = document.getElementsByTagName('input');
var $target = $(event.target);
if( $target.is(inputButton[1]) ) {
alert("Please click the 1st Button first");
} else{
alert('Button 2 Clicked');
}
}
});

I think you can put the second button function in the first one.
$('#btn1').click(function(){
alert('Button 1 Clicked');
$('#btn2').click(function(event) {
var inputButton = document.getElementsByTagName('input');
var $target = $(event.target);
alert('Button 2 Clicked');
}
});
});
You then also won't need the check in the second button.

Try to set a flag
var firstButtonClicked;
$('#btn1').click(function(){
firstButtonClicked = true;
alert('Button 1 Clicked');
});
check firstButtonClicked in second button click.

Call a onkeyup function when click on other button jQuery

I have function which has keyup event on input field which is working fine.
I want to trigger this function also upon click on other button.
Here is my function
function validateChild(el) {
var validated = {};
console.log('Remove button clicked');
var dateOfBirthField = $(el).find('.date_of_birth');
$(dateOfBirthField).on("keyup", function () {
var dateOfBirthValue = $(el).find('.date_of_birth').val();
console.log('Check DoB');
if(validateDateOfBirth(dateOfBirthValue, dateOfBirthField)){
console.log('True');
validated.dateOfBirth = true;
} else {
validated.dateOfBirth = false;
}
validateButton(validated);
});
}
I'm calling this function on document load
function validateForms() {
$(document).find(".child-form").each(function () {
validateChild(this);
});
}
Here i have click event
.on('click', '.removeButton', function (event) {
validateForms();
});
When i click on this remove button it trigger but stop working after this
console.log('Remove button clicked');
How can i trigger keyup event also on this remove button, or there is better way to do this in javascript.
Can anyone help me with this?
Thanks
I have reviewed your three code blocks. Please try following three code blocks respectively.
Your function
function validateChild(dateOfBirthField) {
var validated = {};
var dateOfBirthValue = $(dateOfBirthField).val();
console.log('Check DoB');
if(validateDateOfBirth(dateOfBirthValue, dateOfBirthField)){
console.log('True');
validated.dateOfBirth = true;
} else {
validated.dateOfBirth = false;
}
validateButton(validated);
}
Call this function on document load
function validateForms() {
$('.child-form').on('keyup', '.date_of_birth', function() {
validateChild(this);
});
}
Click event
.on('click', '.removeButton', function() {
console.log('Remove button clicked');
$('.child-form .date_of_birth').each(function() {
validateChild(this);
});
});

button continually only fire once

If keep clicking the same buttons then only fire once. sample: https://jsfiddle.net/h4wgxofh/, For example, if click1 clicked then 2nd time or more times clicks should stop firing, the same as click2 however, if I click the same button, it always fires. Also I want links only trigger once but becomes available if other buttons being clicked. (considering if more buttons) Thanks
HTML
<div class="wrap">
Click1
Click2
</div>
Script
var clicked = false;
$('.wrap').on('click', 'a', function(){
var $this = $(this);
clicked = true;
if(clicked = true){
console.log($this.text());
clicked = false;
}
});
I'm probably missing something here, but why not just bind the event to every link in .wrap and unbind it on click like this :
$('.wrap a').on('click', function(){
console.log($(this).text());
$(this).unbind('click');
});
See this fiddle
Edit : after your comment on wanting one link to be rebound after cliking on another, even though it might not be the cleanest solution, this does the job :
var onclick = function(){
var $el = $(this);
console.log($el.text());
$('.wrap a').off('click', onclick);
$('.wrap a').each(function(id, link){
if($el.text() != $(link).text())
$(link).on('click', onclick);
});
}
$('.wrap a').on('click', onclick);
Fiddle again
See the following code
var clicked1 = false;
var clicked2 = false;
$('.wrap').on('click', 'a', function(){
var $this = $(this);
var clickOrigin = $(this).text();
if(clickOrigin == 'Click1' && clicked1==false){
console.log("Click 1 clicked");
clicked1 = true;
}
if(clickOrigin == 'Click2' && clicked2==false){
console.log("Click 2 clicked");
clicked2 = true;
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="wrap">
Click1
Click2
</div>
Also you can find the jsFiddle.
You need to Distinguish between two links(i used text here you may put whatever scenario ) see this example it may help:-
var clicked1 = 0;
var clicked2 = 0;
$('.wrap').on('click', 'a', function() {
var $this = $(this);
var $text = $(this).text();
//Click2
if ($text == 'Click1') {
clicked1 += 1;
if (clicked1 == 1) {
console.log($text);
} else {
return;
}
}
//Click2
if ($text == 'Click2') {
clicked2 += 1;
if (clicked2 == 1) {
console.log($text);
} else {
return;
}
}
});
Full Demo
To disable both buttons after first click, try:
var clicked = false;
$('.wrap').on('click', 'a', function(){
let $this = $(this);
if( !clicked ){
console.log($this.text());
clicked = true;
};
});
To disable each button after first click, try:
$('.wrap a').each(function() {
let $this = $(this);
$this.disabled = false;
$this.on('click', function() {
if ( !$this.disabled ) {
console.log($this.text());
$this.disabled = true;
};
});
});
Every time someone clicks one of the buttons, your script is setting clicked from false to true, checking if the value is true, then setting it to false again. You need to format it like this if you only want the buttons to fire once (obviously you'd have to duplicate this specifically for each button with different IDs):
var clicked = false;
$('.wrap').on('click', 'a', function(){
var $this = $(this);
if(clicked == false){
console.log($this.text());
clicked = true;
}
});
try this ,much simpler and this will be more useful if you have multiple click buttons
if you had implemented some other way ,this will worth a try
<div class="wrap">
Click1
Click2
</div>
$('.wrap').on('click', 'a', function(){
var $this = $(this);
if($this.attr("data-value") == ""){
console.log($this.text());
$this.attr("data-value","clicked")
}
else{
console.log("Already clicked")
}
});
Fiddle
Instead of putting code on click just on first click disable anchor tag this serve the same thing you wants just find below snippet for more information using this we can reduces round trips to the click functions as well
$('.wrap').on('click', 'a', function(){
$(this).addClass("disableClick");
});
.disableClick{
pointer-events: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="wrap">
Click1
Click2
</div>
I think you can disable anchor link after one click like this
<div class="wrap">
Click1
Click2
</div>
I think you can disable anchor link after one click like this
<div class="wrap">
Click1
Click2
</div>
$(function () {
$('#click1').on("click", function (e) {
$('#click1').on("click", function (e){
e.preventDefault();
e.preventDefault();
});
});
I think its help you.
Just use $(".wrap").one('click', ....
Read the jquery API documentation.

Occur if 3 button are clicked and disable other button

I have in a html page 5 button named 1,2,3,4 and 5.If 3 button are clicked the other button must be disabled.
var clicking=0;
$(document).ready(function(){
$('button').click(function(){
clicking++;
$(this).toggleClass("active");
if(clicking==3){
$('button').click(function(){
$(this).toggleClass("nothing");
})
}
})
})
I tried with this script but it don't work because all the button can be clicked.The if is ignored.
i want that only 3 of this 5 button can be clicked and the other must become disabled.
EDIT: shortened the code
I think this is what you want? Count the number of buttons with .active. If it's three or more, disable all buttons that don't have .active.
JS:
$('button').on('click', function() {
$(this).toggleClass('active');
$('button').prop('disabled',false);
if ($('.active').length >= 3) {
$('button:not(.active)').prop('disabled',true);
}
});
Here's a fiddle.
You should do something like this :
var clicking=0;
$(document).ready(function(){
$('button').click(function(){
clicking++;
$(this).toggleClass("active");
if(clicking==3){
$('button').each(function(){
if(!$(this).hasClass("active")){
$(this).addClass("inactive");
}
});
}
});
});
I didn't try it, but I think you like for something similar.
Ok i am not a master of jquery but i came up with a simple logic to implement what you want to achieve, that is disabling all the other buttons that haven't been clicked after three clicks. Here's my working code:
var count = 0;
var ids = new Array();
$(document).ready(function(){
$('button').click(function(){
ids[count] = this.id;
count++;
if(count == 3){ //three buttons clicked, now time to disable the remaining buttons
for(var i=0; i<$('button').length; i++){ //we'll check for all buttons
var id = $('button')[i].id;
var flag = true;
for(var j=0; j<ids.length; j++){ //checking all the buttons against the buttons that got clicked
if(id == ids[j])
flag = false; //button has been clicked (won't be disabled)
}
if(flag){
$("#"+id).attr("disabled", true); //disabling button
}
}
}
})
})
It's very self explanatory and i added lots of comments but still what i did is:
save the ids of buttons that got clicked, then after three clicks, disabling all the buttons who's ids don't match with the saved ids. Pretty simple.. but im sure you can make the code better as i'm not too good at jquery.
See the Working DEMO here
My sugestion is to use an array so you know witch buttons were clicked.
$(document).ready(function(){
var clickedbuttons = [];
$('button').click(function(){
$(this).toggleClass("active");
var idx = jQuery.inArray($(this).attr("id"), clickedbuttons );
if(idx == -1)
clickedbuttons.push($(this).attr("id"));
else clickedbuttons.splice(idx,1);
if(clickedbuttons.length == 3) {
$('button').each(function() {
var index = jQuery.inArray($(this).attr("id"), clickedbuttons );
if(index == -1)
$(this).attr("disabled", "disabled");
});
}
else {
$('button').each(function() {
$(this).removeAttr("disabled");
});
}
});
})
I'm assuming each button has an id. This will work as you want but you have to have an id in every button.
If you do not want to reenable change accordingly
$(document).ready(function(){
var clickedbuttons = [];
$('button').click(function() {
var idx = jQuery.inArray($(this).attr("id"), clickedbuttons );
if(idx == -1) {
clickedbuttons.push($(this).attr("id"));
$(this).toggleClass("active");
}
if(clickedbuttons.length == 3) {
$('button').each(function() {
var index = jQuery.inArray($(this).attr("id"), clickedbuttons );
if(index == -1)
$(this).attr("disabled", "disabled");
});
}
else {
$('button').each(function() {
$(this).removeAttr("disabled");
});
}
});
})

change text on link when div is open

I have a button on my page
<button id="show1" class="morelinkblack">Find Out More</button>
When clicked it runs this code
$("#show1").click(function(){
$(".hidden-div1").slideToggle("slow");
});
Is there a way of changing the text to say "Close" instead of "find out more" while the div is visible?
You can do:
$("#show1").click(function(){
var that = $(this);
$(".hidden-div1").slideToggle("slow", function() {
if ($(this).is(":visible")) {
that.text("Close");
} else {
that.text("Find out more");
}
});
});
Based on the comments, the div could be opened or closed depending on where the user is directed from. A simple check in the DOM ready can set the text accordingly:
$(".hidden-div1").is(":visible") ? $("#show1").text("Close") : $("#show1").text("Find out more");
Maybe this :
$("#show1").click(function () {
var $div = $(this);
$(".hidden-div1").slideToggle("slow").promise().done(function () {
$div.text(function () {
return $(this).is(":visible") ? "Close" : "Find Out More"
});
});
});
Updated code
$("#show1").click(function() {
var el = $(this);
$(".hidden-div1").slideToggle("slow", function() {
if ($(this).css('display') == 'none') { // <- Updated here to check if div is close or open
el.text('Find Out More');
} else {
el.text('Hide More');
}
});
});
Update button text on document ready / page load
$(document).ready(function() {
if ($(".hidden-div1").css('display') == 'none') {
$("#show1").text('Find Out More');
} else {
$("#show1").text('Hide More');
}
});

jQuery: Check if button is clicked

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();
});
