How do I do this in javascript where when a radio button is selected only certain fields show up to type in?? Please show work (preferably with JSFiddle) :)
<form action="inc/add_p_c_validate.php" method="post">
Professor<input type="radio" name="addType" value="Professor" />
Course<input type="radio" name="addType" value="Course" />
<br><br>Name: <input type="text" name="name" /><br>
Department: <select name="deptName"><option>Department 1</option> <option>Department 2</option></select>
Email: <input type="text" name="email" /><br>
<input type="submit" name="submit" />
</form>
set onclick event of your radiobuttons to call a function that will check radiobutton status and then will show or hide elements of your form inside specified div elements.
jsfiddle sample
<script language="javascript">
function ChangeForm()
{
if(document.getElementById('Professor').checked)
document.getElementById('fieldset1').style.display = "inline";
else
document.getElementById('fieldset1').style.display = "none";
if(document.getElementById('Course').checked)
document.getElementById('fieldset2').style.display = "inline";
else
document.getElementById('fieldset2').style.display = "none";
}
</script>
<form action="inc/add_p_c_validate.php" method="post">
Professor<input type="radio" name="group1" onclick="ChangeForm()" id="Professor" name="addType" value="Professor" />
Course<input type="radio" name="group1" onclick="ChangeForm()" name="Course" id="Course" value="Course" />
<br><br>
<div id="fieldset1">Name: <input type="text" name="name" /><br>
Department: <select name="deptName"><option>Department 1</option> <option>Department 2</option></select></div>
<div id="fieldset2">Email: <input type="text" name="email" /><br>
<input type="submit" name="submit" /> </div>

My html code like this :
<form>
<label for="name">* Name</label>
<input type="text" id="name" required><br>
<label for="name">* Address</label>
<input type="text" id="address" required><br>
<input type="submit" value="Submit">
</form>
I'm using required HTML5 attribute to validate fields.
If user does not input text, it will display HTML5 error.
I want to disable the submit button if any of the required fields are left empty.
How can I do it?
You can disable the pointer events on the button with CSS.
form:invalid>#submit {
pointer-events: none;
}
<form>
<label for="name">* Name</label>
<input type="text" id="name" required><br>
<label for="name">* Address</label>
<input type="text" id="address" required><br>
<input type="submit" value="Submit" id="submit">
</form>
You could also disable the button using Javascript.
function disableField() {
const invalidForm = document.querySelector('form:invalid');
const submitBtn = document.getElementById('submit');
if (invalidForm) {
submitBtn.setAttribute('disabled', true);
} else {
submitBtn.disabled = false;
}
}
disableField();
const inputs = document.getElementsByTagName("input");
for (let input of inputs) {
input.addEventListener('change', disableField);
}
<form>
<label for="name">* Name</label>
<input type="text" id="name" required><br>
<label for="name">* Address</label>
<input type="text" id="address" required><br>
<input type="submit" value="Submit" id="submit">
</form>
you can do it after true
$("#button").prop("disabled", true);
You can try something like this:
$(function() {
$("#input-text").keyup(function () {
if($("#input-text")[0].checkValidity()){
$('#submit-button').attr('disabled', 'disabled');
}else{
$('#submit-button').removeAttr('disabled');
}
});
})($);
<form id="newRecord">
<input type="text" required id="input-text"/>
<button form="newRecord" type="submit" id="submit-
button">Submit</button>
</form>
An more generic solution for multiple forms and supporting multiple inputs and buttons.
It detects the change event directly on forms individually, and then change the disabled attribute for all submit types
function disableFormSubmit(form) {
const buttons = form.querySelectorAll(
'button[type="submit"], input[type="submit"]'
);
const disableButtons = () =>
buttons.forEach(el => (el.disabled = form.matches(":invalid")));
form.addEventListener("change", disableButtons);
disableButtons();
}
document.querySelectorAll("form").forEach(disableFormSubmit);
<form action="/">
<legend>First form</legend>
<input type="text" required> <br>
<input type="Checkbox" required> required checkbox <br>
<input type="submit">
<button type="submit">Button submit</button>
</form>
<hr>
<form action="/">
<legend>Second form</legend>
<select required>
<option value="" disabled selected>Select one</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select> <br>
<input type="radio" required name="radio"> required radio <br>
<input type="submit">
<button type="submit">Button submit</button>
</form>
Personally i would go on an solution using only CSS as a visual cue, unless you need the disabled attribute
Why wont my popup window pop up?
My user should enter information for an appointment. Once Submit is hit a document window should pop up. The submit button appears to work. The clear button is working also. I programmed a function to handle the window and set the onSubmit to return the function.
< script type = "text/javascript" >
function popUpWindow() { //window should return user's name in a window
newWin = window.open('', 'NewWin', 'toolbar=no,status=no,width=500,height=200');
newWin.document.write("<body bgcolor='yellow'><h3>Appointment Confirmation</h3>);
newWin.document.write("
Your name is: " + document["
form "].name.value);
newWin.document.close();
}
</script>
<html>
<head>
<title>Project</title>
</head>
//this form should accept user's input
<body>
<form name="form" onSubmit="return popUpWindow();">
Please enter your name:
<input type="text" name="name" value="" size="50" />

I want to clear all form input data after a submitting all input data to php file how can I clear this data by using jquery function?
You can listen to the submit event and then clear the values of each input like below:
$('#form').submit(function() {
$(this)[0].reset();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="form">
<input type="text" />
<input type="submit" />
</form>
This should work...
$('form').on('submit', function() {
var children = $(this).children()
children.each(function(i, el) {
if ($(el).attr('type') === 'checkbox') return $(el).removeAttr('checked')
$(el).val(null)
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type="text" />
<br>
<input type="text" />
<br>
<input type="checkbox" />iphone
<input type="checkbox" />Android
<br>
<input type="radio" name="gender" value="male" checked>Male
<br>
<input type="radio" name="gender" value="female">Female
<br>
<input type="radio" name="gender" value="other">Other
<br>
<select>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
<br>
<button type="submit"> submit </button>
</form>
try this
$(document).ready(function(){
$('#submit').click(function(){
$('#my_form').find("input[type=text]").val("");
});
});
document.querySelector(".name").value = "";
<form class="form">
<input type="text" class="name"/>
<input type="submit" value="Send" class="submit"/>
</form>
Then the input value will be always empty

You're executing your code before the document is rendered. Either:
Move your code to the end of the document before the closing body tag or
Put your code in a document ready handler in the head like:
$( document ).ready(function() {
// your code here
});
jsFiddle example
$("input[type='radio']").change() will fire for all inputs of type radio button. So, try with:
$("input[type='radio'][name='answer']").change()
I am kind of new to JQuery and Javascript and need your help on what I am missing here. I know the code works in jsfiddle.net but when I actually run it on my computer it's not doing anything. I want to keep the Object Oriented functions in "updated-formcheck.js" file separately.
I have a form validation HTML file with a jQuery function that calls my "updated-formcheck.js" file that checks all the empty fields and returns a msg. But when a submit button is clicked, nothing happens. Can you tell me why?
HTML file:
<script src="updated-formcheck.js" type="text/javascript"></script>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<form id="myform" method="post" action="#">
<fieldset>
<label for="attendee">I am a...<font color="red">*</font>:<br />
<br />
</label>
<select id="attendee" name="attendee" >
<option value="">-- Please Choose --</option>
<option value="RETURNING" >Returning Attendee</option>
<option value="FIRST_TIME" >First Time Attendee</option>
</select>
<label for="fullName"><br />
<br />
Full Name<font color="red">*</font>:</label>
<p><input type="text" id="fullName" name="fullName" value="" />
</p>
<p> </p>
<label for="address1">Street Address<font color="red">*</font>:</label>
<p>
<input type="text" id="address1" name="address1" value=""/>
</p>
<p>
<input type="text" id="address2" name="address2" value="" />
</p>
<label for="city"><br />
City<font color="red">*</font>:</label>
<p>
<input type="text" id="city" name="city" value="" />
</p>
<label for="stateProvince"><br />
State/County/Province:</label>
<p>
<input type="text" id="stateProvince" name="stateProvince" value="" />
</p>
<label for="zipPostalCode">ZIP/Postal Code:<br />
</label>
<p>
<input type="text" id="zipPostalCode" name="zipPostalCode" value="" />
</p>
<input type="hidden" name="submitted" value="true" />
<input type="submit" value="Submit" id="btnSubmit"/>
</fieldset>
</form>
<script type="text/javascript">
$(document).ready(function() {
$('#btnSubmit').click(function(e) {
validateNow(e);
});
});
</script>
In "updated-formcheck.js" file:
function validateNow(eventObj){
var isValid = true;
$('input[type="text"].required, textarea.required, select.required').each(function() {
if ($.trim($(this).val()) == '') {
isValid = false;
$(this).css({
"border": "1px solid red",
"background": "#FFCECE"
});
}
else {
$(this).css({
"border": "",
"background": ""
});
}
});
if (isValid == false) {
eventObj.preventDefault();
alert(this.e);
}else
this.s;
}
Because
$('input[type="text"].required, textarea.required, select.required')
in your code currently return an empty array, so each function is not called.
This is because you are looking for dom elements with a css class "required" that you doesn't have.
To get your code working I added a "required" class, which your js code is looking for, on the city element. I also updated the jQuery bind event to the form submit instead of a button click.
