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);
});
});

Prevent beforeunload function from executing if submit button is clicked

I have the following function that gives a warning to the user if they are exiting the page when the $('.article_div textarea') form field is populated.
$(window).on('beforeunload', function(event) {
var unsaved = "Are you sure you want to exit?";
var text = $('.article_div textarea').val();
if (text.length > 0){
return unsaved;
}
});
However, I would like to prevent this popup from executing when they click the submit button to the actual form.
How can I ammend the function to account for this? The element of the submit button is
$('button.submit_post').

You can create a boolean which gets positive when you click on submit Or remove the event of unload when clicked. The code will be as follows:
var isSubmitClicked = false;
$('button .submit_post').on("click",onClick);
function onClick(e){
isSubmitClicked = true;
}
$(window).on('beforeunload', function(event) {
if(isSubmitClicked){
isSubmitClicked = false;
return;
}
// Rest of your method.
}

How about binding a event handler to the submit event instead of the submit button element?
Maybe like this:
var submitted = false;
$('form').on("submit", function() {
submitted = true;
console.log('submitted');
});
$(window).on('beforeunload', function(event) {
if(submitted){
submitted = false;
console.log('aborted because of submit');
return;
}
console.log('rest of code');
// Rest of your method.
});

Changing required field dynamicly via JS in Contact Form 7

I need to write custom validated form in Wordpress. After the click on For-Author radio button some checkboxes group should be marked as not required. I tried to change "aria-required" attributes to "false" or remove and add class "wpcf7-validates-as-required" but it doesn't work. I also tried to reinit wpcf7 by
$('div.wpcf7 > form').wpcf7InitForm();
but it's also doesn't work.
This is a code sample:
$radio.button.click(function (event) {
isAuthor(event)
});
var isAuthor = function (event) {
if ($(event.target).attr('data-author') == 'true') {
authorClicked = true;
} else {
authorClicked = false;
}
fieldUpdate();
};
var fieldUpdate = function () {
var $text = $('[name=pres-title]');
if (authorClicked) {
$text.prop('disabled', false).attr('aria-required', true).addClass('wpcf7-validates-as-required').attr('aria-invalid', false)
$fieldRequired.each(function () {
$(this).prop('disabled', false).attr('aria-required', true).addClass('wpcf7-validates-as-required').attr('aria-invalid', false);
});
} else {
$text.prop('disabled', true).attr('aria-required', false).removeClass('wpcf7-validates-as-required').attr('aria-invalid', false);
$fieldRequired.each(function () {
$(this).prop('disabled', true).attr('aria-required', false).removeClass('wpcf7-validates-as-required').attr('aria-invalid', false);
});
}
}

A confirmation popup in JS

I am looking into making a confirmation menu in JavaScript to where it will run a set of code depending if you select yes or no.
Now I want it to happen on the window.onbeforeunload event but only when the individual presses "yes" do I want the rest of the code to work. If they press "no" I want the window.onbeforeunload to be cancelled outright. I am wondering if it is at all possible and how. Here is what I have so far. The reason why I want this is because when I run the script the popup shows up on return but before someone would get to choose to stay or leave. The click(); feature starts up erasing the information. I want the .click(); to start up after someone presses "yes" on the return and only if they press "yes".
var validNavigation = false;
function wireUpEvents() {
var dont_confirm_leave = 0;
var leave_message = document.getElementById("kioskform:broswerCloseSubmit");
var leave_safari = document.getElementById("kioskform:broswerCloseSafari");
function goodbye(e) {
if (!validNavigation) {
function disp_confirm()
{
var leaveMessage=confirm("Are you sure you want to leave")
if (leaveMessage==true)
{ if (dont_confirm_leave!==1) {
if(!e) e = window.event;
//for IE
e.cancelBubble = true;
e.returnValue = leave_message.click();
//e.stopPropagation works in Firefox.
if (e.stopPropagation) {
e.stopPropagation();
e.preventDefault();
}
//return works for Chrome and Safari
leave_safari.click();
return '';
//add the code to delete the kiosk information here.
// this is what is to be done.
}
}
else
{
Alert("Returning to the page.")
}
}
window.onbeforeunload=goodbye;
// Attach the event keypress to exclude the F5 refresh
jQuery('document').bind('keypress', function(e) {
if (e.keyCode == 116){
validNavigation = true;
}
});
// Attach the event click for all links in the page
jQuery("a").bind("click", function() {
validNavigation = true;
});
// Attach the event submit for all forms in the page
jQuery("form").bind("submit", function() {
validNavigation = true;
});
// Attach the event click for all inputs in the page
jQuery("input[type=submit]").bind("click", function() {
validNavigation = true;
});
}
// Wire up the events as soon as the DOM tree is ready
jQuery(document).ready(function() {
wireUpEvents();
});

Why not just use window.confirm?

"Merge" LiveValidation with Jquery on a form

This is part of my jquery function that validades a form i have on my website:
/*
validates errors on all the fieldsets
records if the Form has errors in $('#formElem').data()
*/
function validateSteps(){
var FormErrors = false;
for(var i = 1; i < fieldsetCount; ++i){
var error = validateStep(i);
if(error == -1)
FormErrors = true;
}
$('#formElem').data('errors',FormErrors);
}
/*
validates one fieldset
and returns -1 if errors found, or 1 if not
*/
function validateStep(step){
if(step == fieldsetCount) return;
var error = 1;
var hasError = false;
$('#formElem').children(':nth-child('+ parseInt(step) +')').find(':input:not(button)').each(function(){
var $this = $(this);
var valueLength = jQuery.trim($this.val()).length;
if(valueLength == ''){
hasError = true;
$this.css('background-color','#FFEDEF');
}
else
$this.css('background-color','#A8FC9C'); /* Campo preenchido */
});
var $link = $('#navigation_form li:nth-child(' + parseInt(step) + ') a');
$link.parent().find('.error,.checked').remove();
var valclass = 'checked';
if(hasError){
error = -1;
valclass = 'error';
}
$('<span class="'+valclass+'"></span>').insertAfter($link);
return error;
}
/*
if there are errors don't allow the user to submit
*/
$('#enviar_candidatura').bind('click',function(){
var preenchimentoForm=true;
if($('#formElem').data('errors')){
preenchimentoForm=false;
dadosFormularios(preenchimentoForm);
//return false;
}
else{
dadosFormularios(preenchimentoForm);
}
});
});
However, i'm using too LiveValidation (http://livevalidation.com/) to validade fields client-side. Obiously, if the part validated by jquery is Ok, doesn't matter if there's errors on the LiveValidation part because the form is submitted.
So, what i want is to add an if clause or something like that inside this jquery code to verify if there are LV_invalid_fields. If 'yes' then block form from submitting like it's done with the jquery validation part, but i don't know how to do it neither where is the right place in the code above to put this verification. I would appreciate some help. Thanks!

//... live validation codes here
$("#myform").submit( function (event) ) {
event.preventDefault();
if ($(".LV_invalid").length > 0) {
//do not submit
}
else {
//do form submission here
}
}

First, you have to change the binding on the click to a binding on the submit action on the form.
And your function must return false on the submit action to stop the submitting action.
So, change your code like this :
$('#formElem').submit( function (event) ) {
var preenchimentoForm = true;
if ($('#formElem').data('errors')){
preenchimentoForm = false;
}
return preenchimentoForm;
}
You can read some explications about unobtrusive javascript here.

There is an option in the LiveValidation library which is not explained in the documentation http://livevalidation.com/documentation
To prevent LiveValidation's submission while still keeping its validation events, you may use the "afterValidation" option.
Example:
var prevent = function (e) {
e.preventDefault();
};
var yourValidation = new LiveValidation(
"inputID", {
//Your other options
afterValidation: prevent
}
);
yourValidation.add( Validate.Presence, { your options } );
