avoid reloading the page when you press the button - javascript

is precisely the problem when I click on the button the page is reloaded , the solution is to use preventDefault() but as' doing the input control is not performed correctly , or if the pattern is not satisfied does not appear any error
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
$('#go').click(function(event) {
//event.preventDefault();
var use = $('#Username').val();
var passwor = $('#Password').val();
alert("Hi);
// Ajax request here
});
</script>
<div class="container">
<div class="card"></div>
<div class="card">
<h1 class="title">Login</h1>
<form>
<div class="input-container">
<input type="text" id="Username" required="required" pattern=".{4,}" title="Devi inserire almeno 4 caratteri"/>
<label for="Username">Username</label>
<div class="bar"></div>
</div>
<div class="input-container">
<input type="password" id="Password" required="required" pattern=".{4,}" title="Devi inserire almeno 4 caratteri"/>
<label for="Password">Password</label>
<div class="bar"></div>
</div>
<div class="button-container">
<button id="go" ><span>Login</span></button>
</div>
</form>
</div>
</div>


remove the src="jquery-1.11.3.min.js" and it should work.
if you have to add jquery library give it a saperate scrip element.

Wrong use of <script> tag, you need to either load the script content use src, and not both.
<script src="jquery-1.11.3.min.js"></script>
<script>
$(function() { // wait for DOM to load
$('#go').click(function(event) {
//event.preventDefault();
var use = $('#Username').val();
var passwor = $('#Password').val();
alert("Hi");
});
});
<script>
You can either use event.preventDefault() (recommended) or add type="button" attribute to the #go button
<button id="go" type="button"><span>Login</span></button>


A script element can load a script from its text content or a URL specified by the src attribute, not both.
You are loading jQuery, but the content of the <script> never runs.
You need a separate <script> for each of your scripts.
Aside 1: You're generally better off using submit events on form elements than you are with click events on submit buttons.
Aside 2: Make sure your code runs after the HTML for the button is added to the DOM. Otherwise $('#go') won't match any elements.


Try returning false at the end of the click event function.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
$('#go').click(function(event) {
//event.preventDefault();
var use = $('#Username').val();
var passwor = $('#Password').val();
alert("Hi);
// Ajax request here
//Return false to prevent refresh
return false;
});
</script>

How to print a form value using jquery in html

Suppose I have a form with some input values(name, mobile_number, age and gender).
After fill up the form while I clicked submit button, I want to print the form values.
I have already tried with jQuery but not get the exact result.
Here is my result
But I want to print the form data like this
Name : Raff
Mobile Number : 016*******
Age : **
Gender : Male
Here is my form
<form action="{{url('/add-prescription')}}" method="post" id="new_prescription_form">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<div class="row clearfix">
<div class="col-lg-8 col-md-8 col-sm-12 col-xs-8">
<div class="card">
<div class="body">
<div class="row clearfix">
<div class="col-sm-6">
<div class="form-group">
<div class="form-line">

</div>
</div>
</form>
jQuery
function PrintElem()
{
var divToPrint=document.getElementById('new_prescription_form');
var newWin=window.open('','Print-Window');
newWin.document.open();
newWin.document.write('<html><body onload="window.print()">'+divToPrint.innerHTML+'</body></html>');
newWin.document.close();
setTimeout(function(){newWin.close();},10);
}
How to solve this ? Anybody help please.

You have to get the values of input fields and add those into the print HTML, this can be achieved using JavaScript , you don't need JQuery for this.
Update your PrintElem function with this and check
function PrintElem()
{
var name = document.getElementById('name').value;
var mobile_number = document.getElementById('mobile_number').value;
var age = document.getElementById('age').value;
var gender = document.getElementById('gender').value;
var divToPrint=document.getElementById('new_prescription_form');
var newWin=window.open('','Print-Window');
newWin.document.open();
newWin.document.write('<html><body onload="window.print()"><div><p><lable>Name :</lable><span>'+name+'</span></p><p><lable>Mobile Number :</lable><span>'+mobile_number+'</span></p><p><lable>Age:</lable><span>'+age+'</span></p><p><lable>Gender</lable><span>'+gender+'</span></p></div></body></html>');
newWin.document.close();
setTimeout(function(){newWin.close();},10);
}
Hope this works for you

Similarly you can do it for other form fields.
Also use angularjs to achieve same functionalities you can

Scrol down by pressing button in CSS

I have this html code:
<div class="get-start-area">
<input type="email" class="form-control email" placeholder="name#company.com">
<input type="submit" class="submit" value="Get Started">
</div>
and this js code:
(function() {
'use strict';
var btnScrollDown = document.querySelector('.submit');
function scrollDown() {
var windowCoords = document.documentElement.clientHeight;
(function scroll() {
if (window.pageYOffset < windowCoords) {
window.scrollBy(0, 10);
setTimeout(scroll, 10);
}
if (window.pageYOffset > windowCoords) {
window.scrollTo(0, windowCoords);
}
})();
}
btnScrollDown.addEventListener('click', scrollDown);
})();
After pressing Get Started I need to see contact area, but scroll goes just one second and I can see just nearest block of information. So, how can I change the values in the script to increase time of scroll in page?
And this is html of contact section:
<section class="footer-contact-area section_padding_100 clearfix" id="contact">
<div class="container">
<div class="row">
<div class="col-md-6">
<!-- Heading Text -->
<div class="section-heading">
<h2>Subscribe!</h2>
<div class="line-shape"></div>
</div>
<div class="footer-text">
<p>We`ll send you weekly news to make your app more convinient. Stay tune.</p>
</div>
</div>
<div class="col-md-6">
<!-- Form Start-->
<div class="contact_from">
<form action="#" method="post">
<!-- Message Input Area Start -->
<div class="contact_input_area">
<div class="row">
<!-- Single Input Area Start -->
<div class="col-md-12">
<div class="form-group">
<input type="text" class="form-control" name="name" id="name" placeholder="Your Name" required>
</div>
</div>
<!-- Single Input Area Start -->
<div class="col-md-12">
<div class="form-group">
<input type="email" class="form-control" name="email" id="email" placeholder="Your E-mail" required>
</div>
</div>
<!-- Single Input Area Start -->
<!--
<div class="col-12">
<div class="form-group">
<textarea name="message" class="form-control" id="message" cols="30" rows="4" placeholder="Your Message *" required></textarea>
</div>
</div>
-->
<!-- Single Input Area Start -->
<div class="col-12">
<button type="submit" class="btn submit-btn">Send Now</button>
</div>
</div>
</div>
<!-- Message Input Area End -->
</form>
</div>
</div>
</div>
</div>
</section>
So I can't understand why script doesn't work correctly.

Change this line of JS:
window.scrollBy(0, 10);
to this:
window.scrollBy(0, 1);
Edit:
Or any number lower than 10 for that matter

copy value with select() and copy

I'm trying select a input and then copy the text into input, but has trouble identifying the children.
$(".input-group .copyLink").click(function() {
$(this).parent().find('.htmlLink').select();
document.execCommand("copy");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="input-group">
<input type="text" class="htmlLink" value="http://google.cl">
<button class="copyLink">Copy</button>
</div>
<div class="input-group">
<input type="text" class="htmlLink" value="http://microsoft.com">
<button class="copyLink">Copy</button>
</div>
<div class="input-group">
<input type="text" class="htmlLink" value="http://apple.com">
<button class="copyLink">Copy</button>
</div>
Any suggestion?
Thanks!

You can shorten the code little bit since you have a div wrapper and only one sibling:
$(".input-group .copyLink").click(function() {
$(this).siblings().select();
document.execCommand("copy");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="input-group">
<input type="text" class="htmlLink" value="http://google.cl">
<button class="copyLink">Copy</button>
</div>
<div class="input-group">
<input type="text" class="htmlLink" value="http://microsoft.com">
<button class="copyLink">Copy</button>
</div>
<div class="input-group">
<input type="text" class="htmlLink" value="http://apple.com">
<button class="copyLink">Copy</button>
</div>

You need to bind event with your button, based on button event response, you need to find your input box using jquery DOM selector function like "prev". After this, execute your other task with input object.

Detect the name of required field and not validated when submit a form

I create a form in html5 like this example :
<form action="/my/url/insert.php" method="POST">
<div class="row">
name <input name="name" required/>
</div>
<div class="row">
type <input name="type" required/>
</div>
<div class="row">
year <input name="year" required/>
</div>
....
<div class="row">
album <input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save"/>
</div>
</form>
<script>
$('form').submit(function(){
console.log('test');
});
</script>
The problem :
I want to detect the name of the required field that are not validated when submiting and logging it.
for example : if I don't fill the input "album" when submit i detect it before the message "a field is required..."
is there a way to do this ?
thank you.

Here you go.. Loop through each input:required field and get its name with .attr.
$('form').submit(function(e) {
e.preventDefault();
$(this).find('input:required').each(function(){
console.log($(this).attr('name'));
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="/my/url/insert.php" method="POST">
<div class="row">
name
<input name="name" required/>
</div>
<div class="row">
type
<input name="type" required/>
</div>
<div class="row">
year
<input name="year" required/>
</div>
....
<div class="row">
album
<input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save" />
</div>
</form>
Updated
$('form').submit(function(e) {
e.preventDefault();
$(this).find('input:required').each(function(){
if($(this).val()==""){ //check if its empty
console.log($(this).attr('name'));
}
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form novalidate action="/my/url/insert.php" method="POST">
<div class="row">
name
<input name="name" required/>
</div>
<div class="row">
type
<input name="type" required/>
</div>
<div class="row">
year
<input name="year" required/>
</div>
....
<div class="row">
album
<input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save" />
</div>
</form>
Assuming that only required will be the property for validation, above condition will hold good and yea, by default when you say required, browser will have its validation suppressing validation written by you. If you want your validation to work, add novalidate to form as said in one of the comments above..

Select them by property required:
$(function() {
$('form').submit(function(){
$("input:required", $(this)).each(function() {
console.log($(this).attr("name"));
});
});
});
To do a simple required check on your own make a simple "not empty" condition. But for this, your form need the novalidate class, otherwise submit callback will not be triggered and nothing ever happens.
$(function() {
$('form').submit(function(){
$("input:required", $(this)).each(function() {
if( $(this).val() != "" )
console.log($(this).attr("name"));
});
});
});
Full example here: https://jsfiddle.net/vvdh66rb/

You can also do like this:
<form action="/my/url/insert.php" method="POST" onSubmit="return myFunction()">
<div class="row">
<!--I am only giving id to one to show an exmaple you can give to differnt-->
name <input name="name" id="some" required/>
</div>
<div class="row">
type <input name="type" required/>
</div>
<div class="row">
year <input name="year" required/>
</div>
....
<div class="row">
album <input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save"/>
</div>
</form>
<script>
function myFunction() {
var x = document.getElementById('some').value;
if (x == "" || x == null) {
alert('sadsd');
return false;
//You can give anything else than alert
}
}

Disable form Button

I have the following form. The 'continue' button is meant to be disabled until all fields have been completed. I have tried this on jfiddle and the form works as intended, but on the actual .html file online it does not work. For example the button is always disabled even when the fields have been completed, any ideas?

Wrapping your code in document.ready might help.
$(document).ready(function(){
$('#username, #password, #password1, #email, #email1, #title, #firstname, #surname').bind('keyup', function() {
if(allFilled()) $('#continue').removeAttr('disabled');
});
function allFilled() {
var filled = true;
$('body input').each(function() {
if($(this).val() == '') filled = false;
});
return filled;

If it's WordPress, be aware that you can't use $ for jQuery. You have to use jQuery('body input') instead, or wrap you code in the following:
$(function(){
$(document).ready(function(){
$('#username, #password, #password1, #email, #email1, #title, #firstname, #surname').bind('keyup', function() {
if(allFilled()) $('#continue').removeAttr('disabled');
});
function allFilled() {
var filled = true;
$('body input').each(function() {
if($(this).val() == '') filled = false;
});
return filled;
}
});
})(jQuery);
Are you seeing any errors in the console?

Place your code in $(document).ready(function(){ // here }) function as below
$(document).ready(function(){
$('#username, #password, #password1, #email, #email1, #title, #firstname, #surname').bind('keyup', function() {
if(allFilled())
$('#continue').removeAttr('disabled');
});
function allFilled() {
var filled = true;
$('body input').each(function() {
if($(this).val() == '') filled = false;
});
return filled;
}
});

I would try:
$('#continue').prop('disabled',!allFilled());
instead of
if(allFilled()) $('#continue').removeAttr('disabled');
Users may fill out all fields, and then delete one.
