Change submit button text based on radio-button value

How to change submit button text based on which radio-button is active?
Here is my code, but it does not work. It changes text only once.
I have two radio-buttons:
<input type="radio" name="build-team" class="choose" value="build" /> Yes
<input type="radio" name="build-team" class="choose" value="show" /> No
<button class="show-result" data-chooseyes="Yes" data-chooseno="No">Yes</button>
And I have script:
$(document).on('click', '.choose', function() {
var target = $('.show-result');
if ($(this).attr('checked') == 'checked') {
target.html(target.data('chooseyes'));
}
else {
target.html(target.data('chooseno'));
}
})
JSFiddle example

$(document).on('click', '.choose', function() {
var target = $('.show-result');
target.html($(this).val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="build-team" class="choose" value="Yes" /> Yes
<input type="radio" name="build-team" class="choose" value="No" /> No
<button class="show-result" data-chooseyes="Yes" data-chooseno="No">Yes</button>

$('.opt').click(function(){
$('#button').html($(this).val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input class="opt" name="opt" type="radio" value="Yes" checked="checked">Yes
<input class="opt" name="opt" type="radio" value="No">No
<button id="button" type="submit">Yes</button>
This is the easiest answer, no added attributes, only clean HTML + jQuery, it is also important to realize that there must always be a radio selected/checked by default, if not, you would have to validate the field and validating a radio is not cool haha :) have a nice day!

update textfield when radio button is selected and button is pressed Javascript

I have 4 radio buttons, when I select one, I want the default value of the quantity(addNumberOfItems) to be 1.
when a radio button is selected it should update a textfield that holds the quantity. Afterwards I have a button to add to the order. The problem is when I click addToOrderBtn and try and increase the quantity on the textfield(I replace the default 1 with 2 or 3) it always sets it back to 1.
My textfield that keep track of Total items(totalItems), should add what I input into addNumbersOfItems.
I tried to update the value of addNumberOfItems when the button is clicked. but its still set to default value.
Javascipt only please.
Thank you!
Code pen: http://codepen.io/anon/pen/LpJqgj
var addNumberOfItems = document.getElementById("numberOfItems");
var addToOrderBtn = document.getElementById("addToOrder");
var totalItems = document.getElementById("items");
var totalPrice = document.getElementById("total");
if (selected == "Classic" && foodOptionChecked1 == true) {
addNumberOfItems.value = 1;
};
addToOrderBtn.onclick = function() {
document.getElementById('numberOfItems').value = addNumberOfItems.value;
totalItems.value = addNumberOfItems.value;
totalPrice.value = foodClassic[0].smallPrice;
addNumberOfItems.value = "";
};
HTML
<fieldset class="form1 hide" id="choices">
<legend> your Choices </legend>
<p style="margin-left:25%">Which one would you like?</p>
<form style="float: right" id="selectSize">
<input type="radio" id="food1" name="size" value=""><label id="foodLabel1">food1</label>
<br>
<input type="radio" id="food2" name="size" value=""><label id="foodLabel2">food2</label>
<br>
<input type="radio" id="food3" name="size" value=""><label id="foodLabel3">food3</label>
<br>
<input type="radio" id="food4" name="size" value=""><label id="foodLabel4">food4</label>
<input type="text" id="numberOfItems" name="" value="">
<button type="button" id="addToOrder">Add to order</button>
<button type="button">Remove last item</button>
</form>
<p style="margin-top: 15%; margin-left:25%"> Extras! </p>
<p style="margin-top: 11%; margin-left:25%"> How many? </p>
</fieldset>
<fieldset class="form1 hide" id="orderStatus">
<legend> Order Status </legend>
<form>
Items<input type="text" name="" id="items">
Total<input type="text" name="" id="total">
<button type="button">Order Now</button>
<button type="button">Cancel</button>
</form>
</fieldset>

This is because inside getOrder() this line addNumberOfItems.value = 1; make quantity to 1 when you change quantity value
try following code in your getOrder() where you setting default value will solve you problem of quality reset
if (selected == "Classic" && foodOptionChecked1 == true) {
if(addNumberOfItems.value.length == 0)
addNumberOfItems.value = 1;
}
};
but sill i am unable to find why getOrder() call after changing the quality value might be because of code in your main.js

OnClick of RadioButton not working

I was trying to change the text of a submit button on change of radio button .My code for html part is :
<input type="radio" onclick="check()" name="radio-view" data-icon="segment-titlestyle-segonly" id="segment1" value="Yes"/>
<label for="segment1" id="controls">
<span class="ui-btn-text-controls">Yes</span>
</label>
<input type="radio" onclick="check()" name="radio-view" data-icon="segment-titlestyle-segonly" id="segment2" value="No" checked="checked"/>
<label for="segment2" id="controls">
<span class="ui-btn-text-controls">No</span>
</label>
<input type="submit" value="send" name="sendbutton" id="sendbutton"/>
My javascript code is as follow :
function check(){
var x;
x=document.f1.radio-view;
if(x[0].checked){
document.f1.sendbutton.value="PROCEED";
}
else if(x[1].checked){
document.f1.sendbutton.value="SEND";
}
}
But its not changing the test.What can be the reason for it?

If you decide to address elements directly, use their names properly:
var x = document.f1['radio-view'];
... as you cannot access with the dot syntax the properties which names are not valid identifiers. document.f1.radio-view is treated as document.f1.radio - view, which apparently makes no sense.
But actually, I'd rather skip this part completely: if radio-button is clicked, it's definitely set as checked. So this...
<input type="radio" onclick="check(this)" ... />
...
function check(button) {
document.f1.sendbutton.value = button.value === 'Yes' ? 'PROCEED' : 'SEND';
}
... should be quite enough, as this demo shows.

});

Set radio button value in javascript

I am trying to set the value of the radio button via javascript. But I am not being able to do so. What I tried to do was have 4 radio buttons one of which is already selected. If I select some other radio button and click on Refresh, default radio button should be selected.
http://jsfiddle.net/ds345/Un8XK/1/
HTML:
<fieldset data-role="controlgroup" data-type="vertical">
<input type="radio" name="radio" id="x" data-theme="a" />
<label for="x" style="color: White">X</label>
<input type="radio" name="radio" id="y" onclick="axisonoff(this)" data-theme="a" />
<label for="y" style="color: White">Y</label>
<input type="radio" name="radio" id="z" data-theme="a" />
<label for="z" >Z</label>
<input type="radio" name="radio" id="none" data-theme="a" />
<label for="none" style="color: White">None</label>
</fieldset>
<button id = "Refresh" value="Refresh">Refresh</button>
JS:
$(document).ready(function () {
$("#none").attr("checked", true).checkboxradio("refresh"); // if this line is not present initially then it works for the 1st refresh.
});
$("#Refresh").click(function(){
$("#x").attr("checked", false).checkboxradio("refresh");
$("#y").attr("checked", false).checkboxradio("refresh");
$("#z").attr("checked", false).checkboxradio("refresh");
$("#none").attr("checked", true).checkboxradio("refresh");
});
I am sure that I have missed something very small but not able to figure out why this approach is not working.

You should use prop over attr when dealing with boolean attributes.
.attr("checked", false) will add checked="false" to your element.In HTML, <input checked="false" .../> is the same as <input checked="true" .../> or simply <input checked .../> as the attribute simply needs to be present on the element for it to be active.
See this JSFiddle example.
Change your code to use .prop() instead:
$("#none").prop("checked", false)...
Here is a fixed version of your JSFiddle demo: http://jsfiddle.net/Un8XK/8/

What you have missed is that there is no need for script. Simply use a form with a reset button:
<form>
<input type="radio" name="radio" value="0" checked>0<br>
<input type="radio" name="radio" value="1">1<br>
<input type="radio" name="radio" value="2">2<br>
<input type="radio" name="radio" value="3">3<br>
<input type="reset">
</form>
If you really must use script, you can simply return the radio buttons to their default by adding a button to the form:
<input type="button" onclick="reset(this.form.radio);" value="Script reset">
and a function:
<script>
function reset(els) {
for (var i=0, iLen=els.length; i<iLen; i++) {
els[i].checked = els[i].defaultChecked;
}
}
</script>

Alert if ANY radio options are not checked

I have a form with 3 questions that have 3 radio options each. I want the form to send an alert if ANY of the questions are left blank. This code sends an alert only if ALL of the questions are left blank:
if (!$("input").is(':checked')) {
alert("You left one blank!");
}
So, for example, if I have only one question answered, I want the alert to send. Instead, it continues on with the code.

You have 3 radio groups, so there will be 3 checked inputs and 6 unchecked inputs, I suggest:
if ( $("input[type=radio]:checked").length < 3 ) {
alert('Please answer all of the questions');
}

Try this:
$(document).ready(function () {
$("#btn1").on("click", function () {
var count = 0;
var questions = $("div.question");
questions.each(function () {
if ($(this).find("input").filter('[type="radio"]').filter(":checked").length > 0) {
count++;
}
});
if (count >= questions.length) {
alert("all good");
} else {
alert("something not checked");
}
});
});
With the HTML:
<div class="question">
Question 1:
<input type="radio" name="radio1" />
<input type="radio" name="radio1" />
<input type="radio" name="radio1" />
</div>
<div class="question">
Question 2:
<input type="radio" name="radio2" />
<input type="radio" name="radio2" />
<input type="radio" name="radio2" />
</div>
<div class="question">
Question 3:
<input type="radio" name="radio3" />
<input type="radio" name="radio3" />
<input type="radio" name="radio3" />
</div>
<div>
<input type="button" id="btn1" value="Submit" />
</div>
http://jsfiddle.net/4yQHv/1/
You can change if (count >= questions.length) { to be === instead of >= to make sure exactly 1 radio button is chosen for every question. Otherwise, this allows for more than one radio button to be chosen (which isn't exactly possible when they're grouped by name attribute)...but just wanted to point that out.

<form>
<input type="radio" name="facepunch" class="facepunch" value="1" />
<input type="radio" name="facepunch" class="facepunch" value="2" />
<input type="radio" name="facepunch" class="facepunch" value="3" />
<br />
<input type="radio" name="stack" class="stack" value="1" />
<input type="radio" name="stack" class="stack" value="2" />
<input type="radio" name="stack" class="stack" value="3" />
<br />
<input id="button" type="button">
</form>
$(document).ready(function(){
$('#button').click(function(){
if(!$("input.facepunch:checked").val()) {
alert("Please select facepunch");
}
if(!$("input.stack:checked").val()) {
alert("Please select stack");
}
});
});
If you have only few groups of radios you can use this method, this is one way to validate user data.
I recommend you to check out one of the great jQuery Validation Plugins out there:
jzaefferer plugin, bassistance plugin
Also, Make sure you validate it on the server side as well! The user can send request to your server from somewhere else or even disable javascript on his browser

You can loop through all your radio buttons and see if any of them is unchecked:
$('input[type="radio"]').each(function () {
if( ! $(this).is(':checked') ) {
alert('You left one blank!');
return false; //exit function, so alert won't show multiple times
}
});
