my html code-
<form method="post" name="editorform" id="editorform" onsubmit="return validate_editorform(this)" action="#">
<ol><li>
<label for="qtitle"><b>Title</b></label>
<input id="qtitle" name="qtitle" class="text"></textarea>
</li><li>
<label for="tag"><b>Tag</b></label>
<table border="0">
<tr>
<td><input type="radio" name="tag" value="art"/>Art & Living</td>
<td><input type="radio" name="tag" value="travel" class="rdbtn"/>Travel</td>
<td><input type="radio" name="tag" value="religion" class="rdbtn"/>religion</td>
</tr>
.....
my javascript-
function validate_editorform(editorform)
{
var qtitle = editorform.qtitle.value;
var tag = editorform.tag.value;
var question = editorform.question.value;
var nameRegex = /^[a-zA-Z]+(([\'\,\.\- ][a-zA-Z ])?[a-zA-Z]*)*$/;
if(qtitle == "") {
inlineMsg('qtitle','You must enter a Question title.',5);
return false;
}
if(editorform.tag.checked == "") {
inlineMsg('tag','You must Tag your question.',5);
return false;
}
if(question == "") {
inlineMsg('question','You must enter a your Question.',5);
return false;
}
}
For qtitle and question JavaScript is working fine but for radio button (tag) it isn't. Can anyone identify the problem?
Change
if(editorform.tag.checked == "") {
to
if(tag == "") {
if(editorform.tag[0].checked == False... and so on for tag[1]...)

I have a code with button Click. When i click text appears in textbox. It woks. But i have a problem to write anoter type of code. I want to fill the textbox using radio buttons but without button Click. So when I click in a radio I want to show text in textbox. Here is my code.
<script type="text/javascript">
function testResults (form) {
var TestVar1 = form.input[0].checked;
var TestVar2 = form.input[1].checked;
var TestVar3 = form.input[2].checked;
var TestVar4 = form.input[3].checked;
if (TestVar1 == true) {
form.textbox.value = "Earth is...";
} else if (TestVar2 == true){
form.textbox.value = "Mars is...";
} else if (TestVar3 == true){
form.textbox.value = "Jupiter is...";
} else if (TestVar4 == true){
form.textbox.value = "Saturn is...";
}
}
</script>
</head>
<body>
<center>
<h1>Our Universe</h1>
</center>
<form>
Select Planet<br />
<input type="radio" name="input" onclick='check_value(0)'/>Earth<p>
<input type="radio" name="input" onclick='check_value(1)'/>Mars<p>
<input type="radio" name="input" onclick='check_value(2)'/>Jupiter<p>
<input type="radio" name="input" onclick='check_value(3)'/>Saturn<p>
<input type="button" name="button" value="Click" onClick="testResults(this.form)"><p>
<textarea name="comments" id="textbox" rows="5" cols="50"></textarea>
</form>
</body>
To do that on clicking radio butttons a way could be this:
<input type="radio" name="input" onclick="check_value(this.value)" value="Earth" />Earth<p>
<input type="radio" name="input" onclick="check_value(this.value)" value="Mars"/>Mars<p>
<input type="radio" name="input" onclick="check_value(this.value)" value="Jupiter"/>Jupiter<p>
<input type="radio" name="input" onclick="check_value(this.value)" value="Saturn"/>Saturn<p>
and js:
function check_value(txt){
document.form.textbox.value = txt + " is...";
}
See if is this you want.
<script type="text/javascript">
function check_value (value,form) {
if (value == 0) {
form.textbox.value = "Earth is...";
} else if (value == 1){
form.textbox.value = "Mars is...";
} else if (value == 2){
form.textbox.value = "Jupiter is...";
} else if (value == 3){
form.textbox.value = "Saturn is...";
}
}
</script>

On button press the following code will display a message with values collected from all checkboxes. But I want to pass these values (returned by function) as hidden input on submit.
<form action="script.php" method="post">
<input type="checkbox" name="chb1" value="html" />HTML<br/>
<input type="checkbox" name="chb2" value="css" />CSS<br/>
<input type="checkbox" name="chb3" value="javascript" />JavaScript<br/>
<input type="checkbox" name="chb4" value="php" />php<br/>
<input type="checkbox" name="chb5" value="python" />Python<br/>
<input type="checkbox" name="chb6" value="net" />Net<br/>
<input type="button" value="Click" id="btntest" />
</form>
<script type="text/javascript"><!--
function getSelectedChbox(frm) {
var selchbox = [];
var inpfields = frm.getElementsByTagName('input');
var nr_inpfields = inpfields.length;
for(var i=0; i<nr_inpfields; i++) {
if(inpfields[i].type == 'checkbox' && inpfields[i].checked == true) selchbox.push(inpfields[i].value);
}
return selchbox;
}
document.getElementById('btntest').onclick = function(){
var selchb = getSelectedChbox(this.form);
alert(selchb);

I've seen guys like you trying to code my router interface, so I'll help out.
give your form an id cause you'll need it later
<form action="script.php" method="post" id="the_form">
add the hidden input in the form
<input type="hidden" name="values" id="values" value="" />
the button in the form matures to a real submit (amazing)
<input type="submit" ...
your "getSelectedChbox()" function is amazing; don't change anything there, just wanted to give you congratulations for it, it's a great function
now, where it says document.getElementById('btntest').onclick - get rid of all that and add this code instead; this code will do the rest.
document.getElementById('the_form').onsubmit = function(){
var selchb = getSelectedChbox(this);
var values = selchb.join(', ');
if(!values.length){
alert('There was an error. You have to select some checkboxes. ');
return false;
}
document.getElementById('values').value = values;
if(!confirm(" Are you interested in submitting this form now? If not, click accordingly. "))
return false;
}
Or simply copy-paste this whole thing in a file called script.php:
<?php echo var_dump(isset($_POST['values']) ? $_POST['values'] : 'Submit first.'); ?>
<form action="script.php" method="post" id="the_form">
<input type="checkbox" name="chb1" value="html" />HTML<br/>
<input type="checkbox" name="chb2" value="css" />CSS<br/>
<input type="checkbox" name="chb3" value="javascript" />JavaScript<br/>
<input type="checkbox" name="chb4" value="php" />php<br/>
<input type="checkbox" name="chb5" value="python" />Python<br/>
<input type="checkbox" name="chb6" value="net" />Net<br/>
<input type="hidden" name="values" id="values" value="" />
<input type="submit" value="Click" id="btntest" />
</form>
<script type="text/javascript"><!--
function getSelectedChbox(frm) {
var selchbox = [];
var inpfields = frm.getElementsByTagName('input');
var nr_inpfields = inpfields.length;
for(var i=0; i<nr_inpfields; i++) {
if(inpfields[i].type == 'checkbox' && inpfields[i].checked == true)
selchbox.push(inpfields[i].value);
}
return selchbox;
}
document.getElementById('the_form').onsubmit = function(){
var selchb = getSelectedChbox(this);
var values = selchb.join(', ');
if(!values.length){
alert('There was an error. You have to select some checkboxes. ');
return false;
}
document.getElementById('values').value = values;
if(!confirm(" Are you interested in submitting this form now? If not, click accordingly. "))
return false;
}

Have fun.
I have 2 radio buttons. I need to give validations for radio button using javascript. Please tel me whats wrong with my code. Here is the code.
$(function() {
$("#XISubmit").click(function(){
var XIGender= document.forms["XIForm"]["XIGender"].value;
if (XIGender==null || XIGender=="") {
alert("Please select the gender");
return false;
}
document.getElementById("XIForm").submit();
});
Here is my HTML code:
<label>Gender </label>   
<input type='radio' name='XIGender' value='Male' id="XImale"/>Male
<input type='radio' name='XIGender' value='Female' id="XIfemale"/>Female</td>
One more here,
$(document).ready(function() {
$("#XISubmit").click(function () {
if($('input[name=XIGender]:checked').length<=0){
alert("Please select the gender");
return false;
}
$( "#XIForm" ).submit();
});
});
JSFiddle
Here is the code. You will have to create a form and validate it on submit.
HTML:-
<form name="myForm" action="targetpage.asp" onsubmit="return validateForm();" method="post">
<label>Gender</label>  
<input type='radio' name='XIGender' value='Male' id="XImale" />Male
<input type='radio' name='XIGender' value='Female' id="XIfemale" />Female</td>
<input type="submit" value="submit" id="XISubmit" />
</form>
JS:-
function validateForm() {
if (validateRadio(document.forms["myForm"]["XIGender"])) {
alert('All good!');
return false;
}
else {
alert('Please select a value.');
return false;
}
}
function validateRadio(radios) {
for (i = 0; i < radios.length; ++i) {
if (radios[i].checked) return true;
}
return false;
}
Hope this will help you. :)
Enjoy coding.
<form name="formreg" enctype="multipart/form-data" method="post">
<input type="radio" value="male" name="gender" /> Male<br />
<input type="radio" value="female" name="gender" /> Female<br />
<input value="Submit" onclick="return inputval()" type="submit" />
</form>
JS:
<script type="text/javascript">
function inputval() {
var $XIForm = $('form[name=XIForm]');
if ($("form[name='formreg'] input[type='radio']:checked").length != 1) {
alert("Select at least male or female.");
return false;
}
else {
var gender = $("input").val();
//alert(gender);
$XIForm.submit();
alert(gender);
}
}
</script>
You can't get the value of the radio button like that. document.forms["XIForm"]["XIGender"] will return more than one node and you can't get the value property of a list of nodes. Since your using jQuery, this can be made much easier:
$("#XISubmit").click(function () {
var $XIForm = $('form[name=XIForm]');
var XIGender = $XIForm.find('input[name=XIGender]:checked').val();
if (XIGender == null || XIGender == "") {
alert("Please select the gender");
return false;
}
$XIForm.submit();
});
JSFiddle
Use the :checked selector as below
function() {
var len = $("input:checked").length;
if(len == 0) {
alert("Please select a gender");
return false;
}

I have read through lots of postings here and around the net, and I even have books covering this subjective, but I just can't get it to work. I just can't get the Function to pick up the value of the "RadioDrink" variable. I have tried all sorts of combinations Using DOM methods like below and here using a collection (this) and (form) with no luck.
Any help would be appreciated.
function ValDrink(form){
if (form.RadioDrink.value == "soup")
{
alert("Its soup OK!");
return true; // OK
}
======================here is my code.======================
<html>
<head>
<title>Test</title>
<script type="text/JavaScript">
<!--
function ValDrink()
{
if (document.forms.Drinks.RadioDrink.value == "soup")
{
alert("Its soup OK!");
return true; // soup
}
else
{
alert("OK");
return false; // not soup
}
}
//-->
</script>
</head>
<body>
<form method="post" id="Drinks" name="Drinks" onsubmit="return ValDrink()">
<input type="radio" checked name="RadioDrink" value="Tea">Tea<br>
<input type="radio" name="RadioDrink" value="Coffee">Coffee<br>
<input type="radio" name="RadioDrink" value="Soup">Soup<br>
<input type="checkbox" name="CheckMilk" value="Yes">Milk
<input type="checkbox" name="CheckSugar" value="Yes">Sugar
<br>
<input type="submit" name="OKButton" value="Vend">
</form>
</body>
</html>
This will give the value of "Soup" checkbox:
document.forms["Drinks"]["RadioDrink"][0].checked
you need to do this in a different way. first of all your DOM is showing undefined value. you can add different ids to the radio buttons. you can do it like below
<html>
<head>
<title>Test</title>
<script type="text/JavaScript">
<!--
function ValDrink()
{
if (document.getElementById("Rsoup").checked == true)
{
alert("its soup");
return true; // soup
}
else
{
alert("its not soup");
return false; // not soup
}
}
//-->
</script>
</head>
<body>
<form method="post" id="Drinks" name="Drinks" onsubmit="return ValDrink()">
<input type="radio" checked name="RadioDrink" value="Tea">Tea<br>
<input type="radio" name="RadioDrink" value="Coffee">Coffee<br>
<input type="radio" name="RadioDrink" id="Rsoup" value="Soup">Soup<br>
<input type="checkbox" name="CheckMilk" value="Yes">Milk
<input type="checkbox" name="CheckSugar" value="Yes">Sugar
<br>
<input type="submit" name="OKButton" value="Vend">
</form>
</body>
</html>
The problem is that this:
document.forms.Drinks.RadioDrink
returns an array-like reference to all three inputs with that name, it doesn't return a reference to the currently selected one. So you can't just test the value property.
The easiest to explain way to achieve what you want to do is to give the radio buttons unique ids:
<input type="radio" checked name="RadioDrink" id="RadioDrinkTea" value="Tea">Tea<br>
<input type="radio" name="RadioDrink" id="RadioDrinkCoffee" value="Coffee">Coffee<br>
<input type="radio" name="RadioDrink" id="RadioDrinkSoup" value="Soup">Soup<br>
And then directly select the one you want to test:
if (document.getElementById("RadioDrinkSoup").checked) {
alert("It's soup OK!");
return true; // soup
} else {
alert("OK");
return false; // not soup
}
Try your coding like below... it will help you.....
<html>
<head>
<title>Test</title>
<script type="text/JavaScript">
<!--
function ValDrink() {
var radios = document.getElementsByName('RadioDrink');
var radioName;
for (var i = 0, length = radios.length; i < length; i++) {
if (radios[i].checked) {
radioName = radios[i].value;
}
}
if (radioName.toUpperCase() == "soup".toUpperCase())
{
alert("Its soup OK!");
return true; // soup
}
else
{
alert("OK");
return false; // not soup
}
}
//-->
</script>
</head>
<body>
<form method="post" id="Drinks" name="Drinks" onsubmit="return ValDrink()">
<input type="radio" checked name="RadioDrink" value="Tea">Tea<br>
<input type="radio" name="RadioDrink" value="Coffee">Coffee<br>
<input type="radio" name="RadioDrink" value="Soup">Soup<br>
<input type="checkbox" name="CheckMilk" value="Yes">Milk
<input type="checkbox" name="CheckSugar" value="Yes">Sugar
<br>
<input type="submit" name="OKButton" value="Vend">
</form>
You should check for each value in the radio group & use it instead. Something like :
function getCheckedRadio(radio_group) {
for (var i = 0; i < radio_group.length; i++) {
var button = radio_group[i];
if (button.checked) {
return button;
}
}
return undefined;
}
Call it to get selected value. So In your case :
getCheckedRadio(document.forms.Drinks.RadioDrink);
Not a right way to get radios value. Use the following function, also can check this question
function ValDrink()
{
var radios =document.forms.Drinks.RadioDrink;
for (var i = 0, length = radios.length; i < length; i++) {
if (radios[i].checked && radios[i].value==="Soup") {
alert("Its soup OK!"); // soup
return true;
}
}
alert("OK");
return false; // not soup
}
I have two radio buttons. Each one has one associated text box. If I click one radio button and then submit an alert box should be shown if the associated text box is empty. How can I achieve this?
<form action="#" name="form1" id="form1" method="post" onsubmit="return check_workorder()">
<input type="radio" name="click" id="click1" checked="checked" value="date"/>
<strong>Start Date
<input type="text" id="my_date_field" name="my_date_field" class="datepicker" style="width:80px;"/>
</strong>
<script language="JavaScript" type="text/javascript">
new Control.DatePicker('my_date_field', { icon: 'images/calendar.png' });
</script>
</br><br />
<input type="radio" name="click" id="click2" value="order" />
<strong>Work order no
<input type="text" name="workno" id="workno" style="width:100px;"/>
</strong><span class="submit">
<input type="submit" name="submit" value="submit" onclick="return check_workorder()"/>
the javascript is
function check_workorder() {
if (document.forms.form1.elements.click.value == "date") {
var dat = (form1.my_date_field.value);
if (dat == "") {
alert("please select date");
return false;
}
} else if (document.forms.form1.elements.click.value == "order") {
var wor = (form1.workno.value);
if (wor == "") {
alert("please enter work order no");
return false;
}
}
}
if (document.forms.form1.elements.click.value == "date") {
if (document.forms.form1.elements.click.checked) {
//the radio button is checked
}
}
